In line with those, there is a rapid growth of private vehicle ownership. The growth of private vehicles must be fulfilled by enough parking space so that it doesn’t cause parking problems later. This study aims to describe the conditions and evaluate the existing parking management in the case study area and design an effective parking space scenario. The object of this research is the on-street parking area on shopping area, Pemuda Street, Chinatown, Magelang. To obtain an overview of parking management in case study area, several surveys were conducted, including a parking inventory survey, occupancy survey, and parking duration survey. Secondary data collected by interview with the Local Transportation Department and the Local Public Works and Spatial Planning Department. The survey results show that existing parking requirements cannot be met by the existing parking area. However, the traffic conditions around the Chinatown have not shown congestion during peak hour. To further improve the effectiveness of parking management in Chinatown, parallel parking, parking meter implementation, the addition of parking space and the application of parking based on duration can be applied. For further research, research on parking using special transportation software can be done.

This has a huge impact on road users because it can interfere with driving comfort and safety, so it is necessary to analyze the road damage that has occurred, including the type of damage and an assessment of road conditions. The Bina Marga method and a light-weight deflectometer (LWD) can be used to assess road deflection in order to assess road condition. The results of this study obtained priority order values for each segment that were in the range 5-11. The greater the value of the Order of Priority obtained, the better the road condition, whereas the smaller the value of the Order of Priority obtained, the worse the road condition. It was also found that the Bina Marga method and the Light Weight Deflectometer (LWD) tool had a poor correlation, so a comparison between the two could not be made for assessing the condition of the road surface layer.

These potential dams here to be constructed within 5 (five) years in order to overcome the problem of water shortage in the district. However, the government has limited funding source. It is necessary to select the more urgent small dams to be constructed within the limited budget. The purpose of the research is determining the priority of small dams construction in Semarang District. The method used to determine the priority in this study is cluster analysis, AHP and weighted average method. The criteria used to determine the priority in this study consist of: vegetation in the inundated area, volume of embankment, land acquisition area, useful storage, recervoir life time, water cost/m³, access road to the dam site, land status at abutment and inundated area, construction cost, operation and maintenance cost, irrigation service area and raw water benefit. Based on results of cluster analysis, AHP and weighted average method can be conclude that the priority of small dams construction is 1) Mluweh Small Dam (0.165), 2) Pakis Small Dam (0.142), 3) Lebak Small Dam (0.134), 4) Dadapayam Small Dam (0.128), 5) Gogodalem Small Dam (0.119), 6) Kandangan Small Dam (0.114), 7) Ngrawan Small Dam (0.102) and 8) Jatikurung Small Dam (0.096). Based on analysis of the order of priority of 3 (three) method showed that method is more detail than cluster analysis method and weighted average method, because the result of AHP method is closer to the conditions of each dam in the field.

Research methods include sample preparation, manufacture of cement with 0%, 5%, 8%, 12%, and 15% fly ash variations, chemical and physical properties of cement. The parameters measured were the level of chemical composition (%) using X-Ray Fluorescence Spectroscopy (XRF) ARL 9800 OASIS, free lime content (%) by volumetry, insoluble residue level (%) by gravimetry, compressive strength (kg/cm2), and smoothness cement (cm2/g). The results showed that the addition of fly ash increased the SiO2 content of cement, thereby increasing C3S and C2S compounds which are compressive strength components of a cement. Besides, the addition of fly ash is directly proportional to IR levels, compressive strength, smoothness, and inversely proportional to free lime levels. So the addition of fly ash can improve the quality of cement by increasing chemical components, increasing compressive strength, and reducing cracking or expansion of cement.

Lacking in road connetion services, can cause high expense economics which finally encumber society as a whole.  In the last decade, government find difficulties to increase road connection service, either from capacities or also from its qualiaty side. Recent years, the maintenance cost allocation seems to short to fulfill the requirement standard of maintenance. Therefore the toll road constructed by private sector should be mobilize as one of the society participation form in the infrastructure development, besides reduce the monetary burden to government. It is need to learn furthermore, whether the toll road construction oppose against the principle of environment conservation. Principles of sustainable development also consider to the economics aspect. Both aspects, economic and environment have to be considered and in line together. In evaluating a big project, there are some method which could direct or indirectly calculate its cost benefit. Its should be recognized whether the toll road construction comply with the financial, economics and social aspects. In the view of economics, toll road construction investment could mobilized a big amount of money and offering many vacancies. While in economics critism which produce a high unemployment, it should stimulate the growth of economics in a broad way. Meanwhile government should not be encumbered to make such road improvement, which is very difficult to fulfill nowadays.Keywords: toll road investment, community participation, sustainable developmentPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3939[How to cite: Riyanto, B., 2006, Pengembangan Jaringan Jalan Tol antar Kota dalam Perspektif Sistem Transportasi Berkelanjutan, Jurnal Media Komunikasi Teknik Sipil, Volume 14, Nomor 1, pp. 95-105]

Accurate forecasting is critical to the overall success of an airline. An important element in forecasting is passenger volume estimation. The goal is to predict the number of passengers expected between two cities for a given time interval. Based on this forecast, airlines can make decisions about new routes or additional flights on existing routes. Starting January 2020, all flights to Yogyakarta have landed at Yogyakarta International Airport (YIA) except for flights using propeller aircraft such as ATR which can still use Adisutjipto International Airport (JOG). Adisutjipto International Airport currently only serves 3 routes, namely Yogyakarta (JOG) - Jakarta (HLP) RT., Yogyakarta (JOG) - Bandung (BDO) RT., and Yogyakarta (JOG) - Surabaya (SUB) RT.. The opening of Adisutjipto International Airport to propeller aircraft makes it possible to increase flight frequencies or new routes. For that, it is necessary to estimate the volume of aircraft passengers at Adisutjipto International Airport using the gravity model. The most accurate model is Model 5, where the attraction force is separated into the number of residents of the origin and destination zones and the GRDP of the origin and destination zones, as well as the distance impedance factor and ticket rates are also separated.

Soft soil was less well used as the subgrade for construction. The aim is to determine the increase in the unconfined compressive strength and bearing capacity of the foundation due to the addition of lime and volcanic ash on soft soil. Soft soil has undrained shear strength < 25 kPa based on the unconfined compressive strength test. The unconfined compressive strength test has been conducted on the soil-lime mixture and soil-volcanic ash mixture of 3-12% respectively to the weight of dry soil. The highest unconfined compressive strength values were found in soils with 6% of lime and 9% of volcanic ash. The bearing capacity of the foundation on soil stabilized with 6% lime increased 13.7 times, while the bearing capacity of the foundation on the soil with the addition of 9% volcanic ash increased the ultimate bearing capacity of 8.7 times the bearing capacity of the foundation on soft soil. The bearing capacity of the foundation on lime stabilized soil is higher than the bearing capacity of the foundation on volcanic ash stabilized soil.

This research was conducted to evaluate the behavior of beams with stirrup reinforcement of WWF M4 grid. A total of nine beam specimens with dimensions of 330mm x 180mm x 1500mm were made and tested under monotonic loading until failure loads with three variations of stirrup, where each variation was made of three beam specimens and four concrete cylinders. The concrete was a ready mix concrete with an average compressive strength of 22,875 kN at 28 days. Beams were tested on simply supported with two concentrated loads at a distance of 500 mm from each support. The loads was applied incrementally and the middle span deflections were recorded for each increase in loads. The test results show that the stirrups of WWF M4 grid on beam specimens can increase the shear capacity, stiffness and control the occurrence of the first inclined crack. When compared to conventional stirrups (BJTP ∅ 6mm), beams with WWF M4 stirrups show better behavior.

The existing concrete structure must be evaluated on a regular basis as part of the bridge's health inspection. The concrete structure of the Kalikuto Bridge, which is part of the Batang Semarang Toll Road, is evaluated and analyzed in this study. The combination of destructive and non-destructive tests (DT and NDT), such as mapping concrete strength using a core drill and hammer test, concrete density with Ultrasonic Pulse Velocity (UPV), and reinforcement configuration using a rebar scanner. Meanwhile, the carbonation and corrosion of concrete materials were also evaluated. The finite element method software was used to analyze the concrete tensile strength against anchor pullout. Overall, the structural condition of the Kalikuto Bridge is still very good for land transportation routes until the building's design service life, i.e. compressive strength according to specifications, concrete density about 4356.67 – 5275.33 m/s, rebar configuration according to as built drawing, no carbonation and no corrosion in more than 90% of the structure. Anchor pullout will not occur since the tensile force does not exceed simulation results. Periodic maintenance is required to protect the bridge structure from things that can reduce the concrete strength.

This study aims to analyze previous research related to various sampling methods and laboratory tests to understand the characteristics and properties of disturbed soil samples and their test results. Additionally, it seeks to understand developments in mitigating these disturbances, thereby encouraging researchers to continue developing methods and testing equipment that minimize sample disturbance. The methodology involves a literature review spanning the last 70 years, leading to several key conclusions: First, sample disturbance can occur during sampling and laboratory testing, including sampling methods, sample size, testing techniques, and equipment. Second, the most crucial impact of sample disturbance is the alteration in shear strength under both static and dynamic conditions, as well as changes in soil compressibility. To address these issues, this research proposes using a combination of laboratory tests and in-situ testing as an effective alternative to minimize disturbances and validate laboratory test results.

In Semarang, factors like clogged channels, sedimentation, land subsidence, and tidal flooding further complicate drainage management. The Organisation for Economic Co‑Operation and Development (OECD) Water Governance approach, with its emphasis on effectiveness, efficiency, and stakeholder engagement, provides a promising framework for improving water governance. However, its application in Indonesia, particularly in Semarang, remains underexplored. This study evaluates the implementation of OECD Water Governance principles in managing the Tenggang River drainage system to promote sustainable water governance. Using the OECD Water Governance Indicator Framework, the research assesses the application of 12 principles through a combination of literature review, questionnaires, and interviews with government officials and community representatives. A descriptive analysis supported by interview findings reveals that the principles are moderately well implemented, though discrepancies exist between government and community evaluations. Government respondents provided higher scores for the dimensions of effectiveness (4.70), efficiency (4.73), and trust & engagement (4.88), compared to the community’s scores of 4.30, 4.07, and 4.40, respectively. Nonetheless, both groups rated the trust & engagement dimension the highest among all.

Using an experimental study, this paper  explains  the effect of crossties which was installed in compression zone of the beam. The model was a simplification of the plastic hinge of the beam. The beam was enlarged in the center of the span and would be loaded with a cyclic of point load, so as to produced the largest moment and shear fields in the face beam of the column. Moreover, the loading was provided by the displacement control system to achieve the ultimate condition. The results show that the crossties significantly increases the displacement and curvature ductility of the beams of 58.7% and 78.2%, respectively, compared to the beam without confinement. In addition, the load cycle formed by cyclic loading increases to 43 cycles in beam with crossties, meanwhile the beam without confinement can only survive up to 33 cycles. The crossties could also increase the cumulative value of inelastic displacement that occurs up to 98%, whereas its  energy dissipation value is six times than the beam without confinement. On the other hand, the maximum load and capacity moment only increase about 6.5%.

This research was conducted using PLAXIS 2D with Mohr-Coulomb (MC) and Soft Soil (SS) material models. The results showed that the combination of PVD and SC methods provides the advantage that PVD can accelerate the consolidation time and SC can reduce the settlement that occurs in the soil. The use of SS model is greater settlement compared to using Mohr-Coulomb material model with a settlement of 1,641 m for Soft Soil and 0.463 m for Mohr-Coulomb. SC depth variation affects the settlement and settlement time, the longer the SC the smaller settlement and the shorter time, while PVD only affects the time. Combining PVD and SC results in better settlement and settlement time compared to PVD or SC alone. Variations in construction methods result in slight differences for MC material models, whereas for SS material models, construction methods 2 are greater in settlement and shorter time.

The value of R is affected by the size of fine aggregat grain, the density of the concrete beam and the water-cement ratio. The unit of R is MPa expressing the tensile strength of the concrete beam without reinforcement to withstand a buckling failure. The distance between the supports of the concrete beam should not be less than three times of the height of the beam. In this research the size of the concrete beam speciment was 100 mm x 100 mm x 350 mm, the maximum fine aggregate size was varied (300 µm, 425 µm, and 600 µm) and the water-cement ratio was also varied (0.25, 0.22 and 0,20). All speciments were cured by steam curing and were tested after seven days. The results show that the larger the size of the fine aggregat grain and the higher the water-cement ratio, the smaller the R.

The reservoir operation  policy which is able to anticipate those conditions will result in more efficient use of water throughout the whole year season, i.e., minimising spillage during wet (flood) season and yet conserving water during dry season. When the dry season is incoming, the operation policy will direct to release less water than during the normal condition, thus conserving water. When the wet (flood) season is coming, the operation policy will direct to release more water to give attenuation volume in the reservoir such that during the rainstorm it can store the excess weter. The operation policy which has capability to anticipate the incoming condition is developed by employing Stochastic Dynamic Progamming (SDP) imbedded with fuzzy infrencing technique. The performance of the generated operating policy from SDP is evaluated by simulating the reservoir operation inplementing the generated operation policy under three conditions, i.e., normal, dry and wet (flood) conditions. It shows that the use of fuzzy inferencing embedded within the SDP program and in the simulation program can result in more flexible operation policy.Keywords: Pengoperasian Waduk, Optimasi, Fuzzy InferencingPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3897[How to cite: Suharyanto, 2005, Pengoperasian Waduk dalam Rangka Penanganan Bahaya Kekeringan dan Banjir, Jurnal Media Komunikasi Teknik Sipil, Volume 13, Nomor 1, pp. 60-70]

The aim of this research is to find the relationship model between speed, density and volume on Belmera toll road based on a traffic study. The traffic study which embodies volume study and the speed of vehicles were divided into 5 vehicle classification, into 2 traffic lines (Entrance and Exit Tanjung Morawa’s toll gates), was conducted on Friday and Saturday around the peak hour on each traffic current. The study concluded that Greenberg model is the best approach for traffic current on Belmera toll road. According to Greenberg model we acquire a mathematical equation of the relationship between speed-density, volume-density, and volume-speed of Exit Tanjung Morawa’s toll gates as: S=98,100-6,700LnD, V=98,100D–16,700DLnD, V=355,758Se-0,059S and the Entrance as: S=99,312–17,442LnD, V=99,312D–17,442DLnD, V=297,033 Se-0,057S. Based on the observation and application of Greenberg model, traffic indicator (v/c, flow, density) of both current revealed that the level of service of Belmera toll road is C and it’s a fine traffic performance so far. The speed rate (km/hour) and density (pcu/km) revealed that the acquired rate from the observation is smaller than the application of Greenberg model.

The availability of earthquake maps is very useful in spatial planning. The need for spatial planning today is micro spatial planning. Therefore, the 2017 national earthquake map needs to be detailed into a micro zonation map at the district or city scale. The ground acceleration presented in the national earthquake map was the acceleration at bedrock, while in spatial planning it is the necessary acceleration at the surface. Therefore, the purpose of this research was to obtain a map of the earthquake at the surface with a micro-scale. Determination of the acceleration value at the surface was carried out by two models. Model-1, the surface acceleration was obtained by multiplying the results of the PSHA analysis at bedrock by the amplification factor based on SNI-1726. While Model-2, the acceleration value at the surface was directly obtained from the results of PSHA analysis using the average surface shear wave velocity (Vs30) based on data from the USGS. The result of this study showed that from the 2 analytical models used, Model-2 has a higher surface acceleration value than Model-1. Riau Province has 12 districts. in general, the 12 districts were included in the low to moderate risk index class, but there was one district that was close to the high index class, namely Rokan Hulu district.

The study aims to compare the wave height and period of the Sverdrup-Munk-Bretschneide (SMB), Finite Water Depth (FWD), and Joint North Sea Wave Project (JONSWAP) hindcasting methods with field measurement results. Wind data is sourced from NASA Prediction of Worldwide Energy Resources (POWER) Data Access Viewer (DAV) v2.4.9 for 2015-2024. The analysis results show that the wave height of the JONSWAP method is greater than the SMB and FWD methods. The wave height and period of the SMB and FWD methods have almost the same values. The difference between the three hindcasting methods is because the parameters used to calculate the wave height and period are different, the SMB method only uses the effective fetch length parameter (Feff), the FWD method uses the effective fetch parameter (Feff) and water depth (d), while the JONSWAP method uses the effective fetch parameter (Feff) and wind speed (UA). The wind speed (UA) parameter in the JONSWAP method has a very significant effect on wave height and period. For coastal structure planning, the JONSWAP method is more recommended, because the resulting wave height can function as a safety factor.

This research aims to find out the performance of asphalt mixtures AC-WC (Asphaltic Concrete Wearing Course) and HRS-WC (Hot Rolled Sheet Wearing Course) using bitumen results from full extraction of asbuton. The research was done by experimental methods through laboratory tests then its performance was compared to convensional mixtures using asphalt oil with penetration grade of 60. The results obtained showed that the bitumen of asbuton did not meet the specification of bitumen based on penetration grade. Characteristics of hot mixture asphalt using bitumen of asbuton showed better performance in terms of the Marshall stability namely 1871 kg higher than the convensional hotmixture of asphalt, with 1100 kg for AC-WC and 1241.9 kg compared with 1094 kg for HRS-WC. In addition, the results of deformation resistance tests showed asphalt mix with pure asbuton  more resistant to rutting shown by higher dynamic stability value namely 4200 track/mm compared with 492 track/mm for AC-WC and 2739 track/mm compared with 325 track/mm. The modulus resilient value of mix with pure asbuton is also higher at temperature of 25°C and relatively the sameat temperatures of 35°C and 45°C. While the resistance of  fatigue for AC-WC and HRS-WC on the test tensile strain of 150 µs were relatively the same as hotmix asphalt using asphalt oil penetration grade of 60, but on test of  a larger tensile strain has worse fatigue resistance, especially for AC-WC.

Several methods have been used to estimate the PCE value, but based on the literature review, it is stated that the occupancy time method and the speed method are the most applicable for the unsignalized intersection conditions. This study aims to determine the most appropriate PCE value by comparing the occupancy time method and the speed method. To determine the most appropriate method in calculating the PCE of the unsignalized intersection, the calculation of the value of capacity and degree of saturation based on the method of speed and occupancy time is compared with the PCE value of MKJI. The result shows that the most suitable PCE value for unsigned intersections is the speed method. The recommended changes in the value of PCE are unmotorized vehicle PCE = 0.45, motorcycle PCE = 0.17, and large vehicle PCE = 2.2. Determining the correct PCE value is expected to provide accurate intersection performance results and determination of intersection problems.

Previous research indicated that the land conversion rate reaches about 5% per year, so this issue needs a right counter measure. Hence, solution alternatives are needed to select the right measure to utilize tidal lowland reclamation in an optimum way. The main issue is the condition that the farmers in tidal lowland reclamation only consider economic factor without considering the other important factors in utilizing the lowland reclamation, thus it motivates uncontrolled land conversion from tidal agriculture into palm oil plantations. Therefore the other important factors have to be included into consideration. In this case, Analytical Hierarchy Process (AHP) method can be used as an analytical tool in identifying the most precise alternative to achieve the goal. Based on previous studies in several provinces in Indonesia, it was known that the other important factors regarding the issues were very influential. The priority value of each proposed alternative was obtained by using AHP method. The priority value of the first alternative (to stop the land conversion) is 45,66%. The value of the second alternative (to slow the land conversion) is 24,70%. The last alternative (to keep land conversion with or without extensification) is 29,64%. Based on the values, the most precise alternative is to stop the land conversion that occurred recently. Keywords: Land conversion, land use optimalitation, AHP Method ABSTRAK Alih fungsi lahan pertanian yang terjadi pada lahan reklamasi rawa pasang surut saat ini sangat pesat. Berdasarkan hasil penelitian sebelumnya menunjukkan bahwa  kecepatannya mendekati 5% per tahun, sehingga berlangsungnya alih fungsi lahan merupakan sebuah permasalahan yang memerlukan suatu penanganan yang baik. Untuk itu diperlukan alternatif solusi guna memperoleh pilihan tindakan yang tepat dalam mencapai pemanfaatan lahan reklamasi yang optimal. Permasalahan utama saat ini bahwa masyarakat petani dilahan rawa hanya melihat dari satu faktor saja yaitu faktor ekonomi tanpa mempertimbangkan faktor-faktor penting yang lain dalam pemanfaatan lahan reklamasi, akibatnya terjadi alih fungsi lahan pertanian rawa pasang surut dari sawah menjadi perkebunan sawit tanpa kendali. Oleh sebab itu perlu dianalisis apakah keputusan itu telah tepat bila juga ditinjau faktor-faktor yang penting lainnya. Dalam hal ini metode Analytical Hierarchy Process (AHP) dapat digunakan untuk menganalisis dalam mencari alternatif yang baik guna mencapai tujuan tersebut. Dari hasil studi sebelumnya di beberapa provinsi pengembangan lahan reklamasi rawa di Indonesia, telah dapat diketahui bahwa faktor-faktor penting lainnya yang berkaitan dengan tujuan dan permasalahan alih fungsi lahan ternyata sangat berpengaruh. Pada perhitungan dengan AHP telah diperoleh suatu nilai pilihan prioritas dari tiap alternatif yang diusulkan, yaitu alternatif 1 (alih fungsi lahan dihentikan) sebesar 45,66%, alternatif 2 (alih fungsi lahan diperlambat) sebesar 24,70%, dan alternatif 3 (alih fungsi lahan tetap berjalan, tanpa atau dengan ekstensifikasi) sebesar 29,64%. Oleh karena itu alternatif yang dinilai lebih tepat untuk pemanfaatan lahan rawa pasang surut adalah menghentikan alih fungsi lahan yang terjadi saat ini. Kata kunci: Alih fungsi lahan, optimalisasi pemanfaatan lahan, Metode AHP.

Connections between LVL Sengon and concrete on this composite floor system are the weakest part so that a majority of structural damages are concentrated at these joints. This study discusses the lateral resistance of lag screw joints in a composite system of LVL Sengon and precast concrete. The lateral joint resistance was evaluated through quasi-static loading upon double shear test specimens having two screws at every single shear. Variation of the specimens includes precast concrete compressive strength of 20.71 MPa and 25.29 MPa, screw diameter of 6 mm length 101.6 mm and 8 mm length 101.6 mm and 127 mm, and angle of lag screw axis against the wood fiber of 60° and 90°. The result shows that lateral resistance of the test is greater than that of EYM, SNI, and EC5 predictions. Joint failure in this experiment is due to failure in wood fiber along with the occurrence of one up to two plastic hinges in the screw.

Akan tetapi pemakaiannya kebanyakan hanya pada jalan-jalan perumahan yang tidak mempunyai beban kendaraan yang cukup berat. Hal ini disebabkan adanya pengertian bahwa perkerasan dengan paving block tidak mempunyai nilai struktur dan oleh karenanya jalan akan mudah mengalami penurunan jika dipakai untuk jalan dengan beban yang berat. Pada tahun 1976 dilakukan percobaan pembebanan terhadap paving block oleh J. Knapton, seorang pakar dari Cement and Concrete Association dari Inggris. Terbukti bahwa lapis perkerasan jalan dengan paving block mampu menyebarkan tegangan vertical yang timbul akibat beban lapisan lalu-lintas ke lapisan perkerasan di bawahnya dengan baik. Pengalaman di negara-negara yang telah lama menggunakan paving block seperti Belanda, dengan menggunakan bahan lapis pondasi atas maupun bawah (base dan sub-base) serta tanah dasar yang memadai dan memenuhi syarat perkerasan, paving block dapat pula dipakai di jalan-jalan raya dengan beban kendaraan yang berat dengan tidak mengalami penurunan yang berarti.Keywords: Small element (concrete paving block) as a pavement surface layerPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3888[How to cite: Rusbintardjo, G., 2004, Small Element Pavement Structure and Its Deformation Behaviour, Jurnal Media Komunikasi Teknik Sipil, Volume 12, Nomor 3, pp. 60-74]

The highest water loss occurred in January of 46.85% and the lowest in May of 33.43%. This is still very far from the standard 20%. The current condition of the Pasuruan City PDAM distribution pipeline network is that all systems are connected to each other, so that there are no separate systems. Efforts that can be made by PDAM Kota Pasuruan to reduce water loss and interconnection networks are to isolate the piping network by establishing a DMA (District Area Meter). Formation of DMA requires hydrolysis modeling simulation of distribution pipeline network using Epanet 2.2 software. Besides using Epanet 2.2 software, Quantum GIS 3.16.16 software is needed to create a pipeline. The validity test in the field uses the discharge parameter with a correlation coefficient between EPANET and field discharge data obtained at 0.61. The formation of DMA with good results to reduce air loss is by reducing air pressure, if the air pressure decreases, the air loss will be lower.

Fly ashes at power plants overload the landfills and requires complete handling solution. The utilization of fly ash in Indonesia are facing the issues, one of these is the categorization of fly ash as a hazardous waste. As a result, its utilization requires permissions from the ministry of environment and forestry. In this paper, a comparative study of fly ash classification as hazardous waste in India, United States of America, China and Vietnam was conducted. India and China are the coal importer from Indonesia. US regulation was once referred when drafting PP number 101. Vietnam is chosen as comparison in Southeast Asia. The Toxicity Characteristic Leaching Procedure (TCLP) results of fly ashes from 16 Indonesian power plants proved that their toxic content was lower than the TCLP parameters in the regulation. Acute Oral Toxicity Test (LD50) results showed that fly ash and bottom ash with dosage up to 7000 mg/kg did not cause fatalities. This study is a reference for the Indonesian government to verify the status of fly ash to be utilized as much as possible in various fields.

The provinces of Aceh, Central Kalimantan, and Maluku are three regions representing parts of Indonesia that have a variety of rainfall distribution and climatic conditions. This research was conducted to determine the influence of the El Nino and La Nina climate anomalies on these three regions by looking at the areas that have a dominant influence due to these climate anomalies. The research used BMKG Indonesia rainfall data with a total of 16 rainfall stations and a data range of 22 years. The methods used for modeling are the Fast Fourier Transform (FFT) and Lomb Periodogram to obtain rainfall spectrum data. Then, the amplitude value was obtained, and a comparison of the data from the two methods was carried out to determine the recurrence value and the area with the highest impact due to climate anomalies. The results of data analysis according to the FFT and Lomb Periodogram showed that the highest affected area was the eastern part of Indonesia, namely Maluku Province, with the dominant frequency according to the FFT method being 5.61 years with a PSD of 7.67 mm2 and the Lomb Periodogram 6.06 years with a PSD of 18.64 mm2. Based on the average PSD value, using both FFT and Lomb Periodograms, it also shows that the influence of El Nino and La Nina is greatest in the eastern part of Indonesia; as you move towards the west, this influence decreases. The smallest influence occurred in western Indonesia. This shows that the influence of ENSO is more dominant than the influence of IODM.

We conducted paired comparisons of ayu distribution between the upper and lower sections of a test watercourse using several velocity conditions (10, 30, and 40 cm/s for juveniles; 20, 30, 50, 70, and 90 cm/s for adults). In upper watercourse sections, juvenile ayu preferred velocities of 30 cm/s and 40 cm/s, and adults preferred a velocity of 50 cm/s. Even when a highly preferred illumination condition of 4000 lux was present in the lower section, fish maintained a higher distribution in the upper section. We design a procedure to calculate rheotaxis preference and built it into our fish behavior simulation model on geographic information system (GIS) software. The model successfully predicted natural migration behavior of fish.

Pile reinforcement is an alternative to stabilize and increase the bearing capacity of soft clay soils. This study is expected to determine the capacity of the pile group from observations through a small-scale laboratory model and its comparison with the results of the analysis. Reinforcement of the piles used are concrete piles and wooden piles. The research was conducted through model testing on single piles and group piles in soft clay soil. The piles have a length of 20 cm and a diameter of 2 cm with the number of 1, 2, 4, and 9 piles. The study results show that the overall bearing capacity of the observed results is not much different from the results of the analysis. The average bearing capacity of the wooden and concrete piles is 20% and 18% greater than the analysis. The increase in pile capacity for each additional number of piles from the observations is not as high as the analysis. There is a tendency for the soil in the pile group to move down together, so that the capacity value of the pile group on soft clay is smaller than the single pile capacity value multiplied by the number of piles in the pile group.

This study investigates the dynamic responses of both structures under wave excitation. The floating wind turbine is modeled as a cantilever column with a lumped mass at the top, while the floating house is idealized as a single-story portal frame. Both structures are supported by pontoons, which are represented as beams on elastic foundations using the Winkler foundation theory. Wave loads are modeled based on linear wave theory and Froude-Krylov forces. The analysis is conducted in the time domain using the Finite Element Method and Newmark-Beta integration scheme. The results show that the floating wind turbine experiences a maximum drift of 61.986 mm, heave of 104.310 mm, and pitch of 0.141°, whereas the floating house experiences a maximum drift of 35.587 mm, heave of 60.621 mm, and pitch of 0.408°. The highest internal forces occur in the pontoon section of both structures, indicating that the pontoon plays a significant role in resisting wave loads. This study contributes to a better understanding of the dynamic behavior of floating structures and demonstrates that a simplified 2D modeling approach can be effectively used as an initial step in designing stable and efficient floating systems.

So it is important to know the correlation between the various land use changes to the discharge within a watershed. This study is a preliminary study in an attempt to assess the correlation between land cover index and peak discharge, with case studies in the Beringin River Basin.The peak discharge with the return period of 2, 5, 10, 20, 50 and 100 years are computed with HEC-HMS software, developed by Hydrologic Engineering Centre (HEC) and US Army Corps of Engineers which computes the runoff discharge from the precipitation. As for land covered index (LCI), it is defined as the sum of the land-use index (LUI). The result of the case study shows the strong correlation between the land covered index with the the runoff discharge with such relation : Q100 = -22.42LCI2 + 214.30LCI - 10.62, Q50 = -18.33LCI2 + 181.87LCI - 20.19, Q20 = -14.30LCI2 + 145.27LCI - 15.61, Q10 = -11.36LCI2 + 118.41LCI - 12.29, Q5 = -8.42LCI2 + 91.27LCI - 8.9 and Q2 = -4.44LCI2 + 53.54LCI - 4.5.

Water in the face of this earth are not directly derived from the rain. All living things need water to survive. Water management should be done as quickly as possible so that its availability is maintained. Along with the development of the times and increasing daily population in Indonesia, the demand for water continues to increase. Indonesia has a tropical climate with two seasons, the dry season and the rainy season. During the dry season of drought, while in the rainy season floods. One reason is the change in land use that result in water catchment areas disappear and be replaced by buildings some hydrological model was developed to determine the water balance, such as infiltration models. Infiltration models are used to determine how much of the surface runoff or inundation (ponding) which can be infiltrated. The purpose of this study is to analyze the model's ability to absorb water in a simple infiltration runoff, infiltration simple models to analyze the influence of the flow between, to analyze the efficiency of a simple infiltration models to infiltration, and a simple model to analyze the influence of water turbidity in a state of unsaturated and saturated water. The results showed that the soil with plants media can reduce runoff and improve water quality due to rain than vacant land.

This research aims to determine the effect of sea water on geopolymer concrete using fly ash and white soil as cement substitutes with testing parameters for compressive strength, permeability and microstructure. The test objects used were cylindrical in shape measuring 150x300 mm and 100x200 mm. The ratio of fly ash and white soil used was 85%:15% and the activator used was NaOH 8M and Na2SiO3 with a ratio of 1:2,5. The mixture proportion using a ratio of 1 fly ash: 1,497 sand: 2 split: 0,451 alkali activator with a mutual plan is 35 MPa. Tests were carried out after the concrete had gone through a curing process for 56 days, then the concrete was conditioned without soaking and with soaking for 28 days. Tests were carried out at concrete ages of 56 and 87 days. The test results show that geopolymer concrete with the influence of sea water has a higher compressive strength value and a smaller permeability coefficient compared to concrete without the influence of sea water. Microstructural testing of geopolymer concrete under the influence of sea air produces a matrix-shaped structure morphology that is denser with fewer pores compared to concrete without the influence of sea air.

One of the most common damages is potholes. The cyclic load is the repetitive load caused by the wheels of a vehicle. Stabilization of the subgrade needs to be done to overcome this problem, namely by adding lime. The lime used is quicklime from Sampang, Madura. The research was conducted to obtain the optimum lime mixture in the soil. CBR test was conducted on the soil with 3%, 5%, and 7% lime mixture. After that, cyclic loading was applied to analyze its effect on the CBR value. The original soil had a CBR value of 11.36% which then decreased to 5.79% after cyclic loading. The CBR values of 3%, 5%, and 7% lime-stabilized soil were 31.96%, 35.22%, and 34.48%, respectively. The optimum lime mixture in this study is 7% with a CBR value of 34.48% and a decrease in CBR value due to cyclic loading to 30.74%. Stabilization with lime can increase the CBR value up to 5% lime mixture. The addition of excess lime will reduce the CBR value. In addition, the decrease in CBR value due to cyclic loading decreases with the addition of lime. This is because the absorption and flocculation reactions by lime cause changes in the distribution of soil grain gradation.

A foundation with a lateral load is due to overturning force relying on good contact between the pile and the soil. This research is about a wll foundation or a rigid pile due to lateral loads on clay, using a cylinder pile model 85 mm diameter with various ratio length of pile (L/D) = 4 to 5 and ratio lies of load (e/L)=1,2 and 4. The results are: (1) Increasing ratio lies of load (e/L) so decreasing maximum lateral load (Pmax) can be supported by pile foundation, and the increasing maximum displacement and maximum moment. (2) Maximum deflection occur at surface soil with rotation point at average L/3 from bottom of pile, and maximum moment occur at L/3 from surface soil. (3) The maximum moment of result laboratory test are smaller than the maximum moments of result numeric analysis with consideration value between 1 to 1.5. These differences are caused by the influence of soil processing during laboratory test so they can influence the value of soil parameters. Based on consideration value, the prediction of maximum moment capacity by curve p-y method can be used in the design of pile foundation by considering the use of safety factor=2.

This slab measures 2000 x 850 x 150 mm3 of regular reinforced concrete (old production) or prestressed concrete (new production) quality K-500. After several times of use, damage occurs mainly at the end of the slab in the form of spalling. The objectives of the study and evaluation were: (1) observing damage; (2) material quality data; (3) numerical modeling by taking into account material properties, loading and soil conditions; and (4) providing slab design recommendations including materials and geometrics. The method of study and evaluation of slab damage was done by observing the damage, taking concrete core-case and testing it in the laboratory, and modeling the slab structure with various parameters (soil data, concrete quality and slab geometry). Field observations and analysis results show that concrete slab spalling occurs initially at the edge (850 mm wide) which in turn causes the effectiveness of the pre-tension force to be suboptimal and finally the concrete spalling volume increases. Apart from the frequency of collisions during installation and slab deformation when supporting vehicle loads. Concrete spalling problems also due to inappropriate concrete quality.

The site investigation data and geophysical measurements on 7 sites in northern Thailand were collected. The multi-springs element model was implemented in finite element ground response analysis. Several parameters, such as peak ground acceleration, peak ground velocity, amplification factor, excess pore pressure ratio, were observed. Furthermore, the correlation from the ground motion parameters was generated to estimate liquefaction potential, which was represented by excess pore pressure ratio. The result showed that the excess pore pressure ratio was relatively well correlated with several ground parameters, such as amplification factor, velocity-acceleration ratio, and factor of safety against liquefaction. The results could be also used for the engineering practice in predicting liquefaction potential in Northern Thailand.

However, variability in compressive strength due to material composition poses challenges to its broader adoption. Traditional evaluation methods are often time-consuming and resource-intensive, necessitating the development of precise and efficient predictive tools. This study introduces the optimized least squares moment balanced machine with feature selection (OLSMBM-FS), an advanced AI-based model for accurately predicting GPC compressive strength. The model incorporates backpropagation neural networks (BPNN) for weight assignment, least squares support vector machines (LSSVM) for hyperplane optimization, and the optical microscope algorithm (OMA) for hyperparameter tuning. The study employs a systematic dataset, implementing normalization and feature selection techniques to improve the accuracy and efficiency of the model training process. The OLSMBM-FS was validated using 10-fold cross-validation and demonstrated superior performance compared to other machine learning models. It achieved the lowest RMSE (4.279), MAE (2.291), and MAPE (6.59%), alongside the highest R (0.901) and R² (0.813), confirming its robustness and predictive accuracy. These findings highlight the potential of OLSMBM-FS as a reliable tool for predicting GPC compressive strength, supporting its broader application in sustainable construction practices.

One of the advantages of genetic algorithms is that they have the ability to solve complex optimization problems in a simple way. By using genetic algorithms, the near global optimum can be achieved easily. Although in the early development, binary coded genetic algorithms are more popular, recently real coded genetic algorithms are widely used to solve engineering problem’s optimization. The advantage of using real coded genetic algorithms is the ability of the crossover operator to explore a larger domain of interest. As a result the use of crossover in real coded genetic algorithms may have a detrimental effect, as it can explore the domain that is very far from the expected domain. In the civil engineering area, most variables are positive. Therefore, it is needed to develop a crossover operator that can produce positive-only offspring. In this paper an asymmetric crossover is proposed to solve this problem. It is shown in the experiments that this crossover has a good performance in achieving optimum results.

One example of non-engineered brick walls building is Bendung Village Head Office in Serang, Banten, which was damaged by the 2019 Pandeglang earthquake. This building was built without reinforced concrete beams and columns known as unconfined masonry buildings. In this study, the building will be redesigned with ETABS software to determine the similarities between the structural weaknesses from ETABS and the actual damage. The results of the structural analysis give a time period of 0.814 seconds, a base shear force of 195.5 kN, and a stress on the wall that is 50% similar to the real damage. Then, the same building was designed following the rules and regulations for earthquake resistant buildings in Indonesia so that it became a confined masonry building. The result is a time period of 1.586 seconds, a base shear force of 114.2 kN, and a brick wall that is not damaged when exposed to earthquake loads. However, the dimensions and reinforcement of beams and columns that comply with the minimum requirements for earthquake resistant buildings in Indonesia need to be enlarged because their strength capacity is exceeded by the working load.

Capacity-based approaches often exacerbate these conditions, highlighting the need for a sustainable transportation concept. The government has designated the development of public transportation as a national priority program, one of which is through bus rapid transit (BRT). To ensure the efficiency, reliability, and attractiveness of BRT, the implementation of bus signal priority (BSP) is essential. This study aims to evaluate the performance of passive and active BSP strategies at signalized intersections within a BRT system using VISSIM microscopic simulation. The strategies analyzed include cycle time adjustment, phase splitting, red truncation, green extension, and phase insertion. The simulation results indicate that the most effective strategies are cycle time adjustment with the early cut off concept for passive BSP and phase insertion for active BSP. The performance of BSP strategies is influenced by the number of phases, traffic movement patterns, and bus service frequency, which vary according to the applied strategy. This study recommends selecting BSP strategies through comprehensive simulation study to achieve both effective performance and cost efficiency before implementation.

The strength of stud shear connector specified on SNI 03-1729-2013 only considers the effect of stud diameter, however the length of a stud may influence its behavior and strength. This research observes the effects of length and diameter (𝓁/𝒹) of shear connectors on the strength. This research was conducted using the push out method explain in AS-4347- Part I. The test specimens observed in this research were concrete and steel composites, composing IWF 350x175x11x14 mm and concrete blocks of size 450x225x160 mm. The studs were made of steel reinforcements with diameter (𝒹) of 10, 16 and 22 mm, were welded on IWF with 5 mm weld thickness. The length of studs for each stud diameter were 4d, 5d, and 6d. The results indicate that the increase in stud diameter will increase the load capacity of stud. The length of studs effect its load capacity. A slim stud experiences large bending moment at the base of the shear connector. The results show that the highest value of load capacity is measured at specimens with 𝓁/𝒹 ratio of 5.

The Bar Chart is usually completed with S Curve, that present the cumulative earned of work from time to time. The S Curve can be used to controlled the progress of work in any time. The analysis of Earned Value Concept, that analyze cost and time consumed of work simultaneously, is based on S Curve either. In many cases, the shape of S Curve is formed unless reffered to certain rule, so that the shape of letter “S” some times too steep or too slope slightly. To improve the shape of S Curve, Miller introduced the concept of S Curve that composed from three mathematic’s formulas. The three formulas that form three parts of  the curve are y = 0,0225 x2, y = 1,5 x – 25 , and y = - 125 + 4,5 x – 0,0225 x2  respectively. This curve is ideal, whereas the earned of the work in a certain unit time changes gradually, therefore meet the concept of resources levelling. Miller divided the duration of project excecution in three parts. Each part has a same length of  periode. The study of different length of periode for three parts shows that S Curve is not ideal, proved by the fluctuation of earned of work in significant value.                Keywords : S Curve, Earned of Work, Resources LevellingPermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3661[How to cite: Sumarningsih, T.

The check dam has more deposited coarse sediment load than fine sediment load. Fine sediment that escapes the check dam will flow further and eventually enter the reservoir pond. Therefore it is necessary to build a building that can capture fine sediments. Construction is planned as a system of sediment trap in irrigation channels. The purpose of this study is to analyze the possibility of applying the sediment trap in the river to deposit sediments that escape the check dam. The analysis begins with the selection of the location of the sediment trap, then calculate the dimensions of the sediment trap and the amount of sediment that has settled. Based on the analysis of the selected dimensions with several combinations of gradation of sediment grains, sediment deposition that occurs ranges from 42 - 68%. So it can be concluded making the sediment trap in the river can be done. However, for the application of these sediment traps further research is needed regarding the dimensions of sediment traps that are most optimal for sediment deposition.

The dimension of surge tank is designed based on water mass oscillation result in minimum hydrodynamic pressure, such that it can determine form, type, and configuration of the tank. The sudden increase in hydrodynamic pressure (positive water hammer) is caused by abrupt decrease in water discharge to the turbine to reduce load to the generator. This positive water hammer is dependent on the discharge and time of closure of the valve. Mathematical equation that describes mass oscillation in the reservoir-pipe channel-surge tank is dynamic and solution can be easily using numerical techniques. This paper demonstrates the water hammer oscillation in a surge tank. The result shares that, 1) when the ratio between surge tank area (As) to the pipe area (AT), As/AT below 5, the maximum increase in water pressure is significant, ii) when the ratio As/AT greater than 5, the increase in water pressure is not significant and tends to have slight differences.

In Indonesia, clay soils are quite common and tend to have low bearing capacity. To increase the bearing capacity of clay soils, it is necessary to carry out soil improvement and stabilization measures. Soil stabilization can be done by adding stabilizing materials such as lime and marble powder. Before stabilizing the soil, it is necessary to test soil characteristics such as testing water content, unit weight, Atterberg limit, specific gravity, sieve analysis and hydrometer. This research was carried out to obtain the most optimum composition of the stabilization mixture. This research used lime additives with compositions of 1.5% and 3%, respectively, marble powder was added with compositions of 3%, 6% and 9%. After that, a compaction test is carried out to determine the optimum water content and maximum dry weight. After getting the results from the compaction test, the soil bearing capacity can be analyzed using the Unconfined Compression Test. The test results showed that the addition of 3% lime and 9% marble powder resulted in a significant increase in compressive strength and shear strength values in clay soil. Closed-molded test specimens show an increasing trend in compressive strength values better than open-molded specimens.

Titab Dam is one of the dams in Indonesia that has multifunction as irrigationwater, raw water and hydropower. This dam is a type of rock fill dam with an upright core which has a peaklength of 210 m, a width of 12 m, and a height of 78 m from the deepest foundation. This dam was built withrelatively complex geological conditions and landslides occurred on the spillway walls and springs were foundin the landslides so it was necessary to analyze the potential for piping due to the presence of springs. Thisstudy examines the potential for piping due to the influence of springs near the dam. The study was conductedbased on instrument observations during the inundation period from 2016 to 2019. The analysis was carriedout by calculating the acceptance criteria (KP) for seepage and seepage index (Qi) to determine seepagebehavior in the dam body and a safety factor analysis (FK) for piping hazards was carried out by comparingthe hydraulic gradient based on piezometer instrumentation readings and the hydraulic gradient of the dambody core material. Based on the calculation of the seepage acceptance criteria and the seepage index, theseepage that occurs in the Titab Dam is not safe because it exceeds the requirements, the average seepageoccurs is 6.350 > 0.56 liter/minute/m and Qi > 1. However, the analysis of the safety factor of piping hazardis still safe that is equal to 8,390 > 4.

It was shown during flood that occured on January 1990, which in that time flood water overtopped of the dikes and caused dikes collapsed in some places and flood was ocurred around Simongan area. This research was  made because there was  a plan to change the Simongan Weir into barrage, in order to make flood water level of  the Garang River  lower during flood. The crest of the Simongan Fixed Weir would be cutted in 3.7 m height  in order to make flood water level lower, and to keep the water level remain the same during normal condition, some gates would be installed above the cutted weir crest as barrages. This situation would change river morphology of the Garang River and  West Flood Way.

This research examines the potential of pineapple leaf ash as a partial cement substitution material to produce more environmentally friendly concrete. An experimental study was conducted with seven variation percentages of pineapple leaf ash substitution (0%, 7.5%, 10%, 12.5%, 15%, 17.5%, and 20%) by cement weight, using 150x300 mm cylindrical specimens. Testing included workability, density, and concrete compressive strength at 28 days. The results showed that slump values decreased with increasing percentages of pineapple leaf ash, from 9.5 cm in normal concrete to 3.0 cm at 20% substitution. Concrete density increased from 2250 kg/m³ in normal concrete to a maximum value of 2335 kg/m³ at 12.5% substitution, then decreased at higher percentages. Optimal compressive strength was achieved at 12.5% substitution with a value of 34.70 MPa, increasing 22.79% compared to normal concrete (28.26 MPa). This research concludes that the optimal pineapple leaf ash substitution is at 12.5%, resulting in significant improvements in concrete density and compressive strength, although with a decrease in workability that must be considered in its application.

In fact, these delays can also be caused by factors that actually are the responsibility of the owner, resulting in project completion exceeding the contract target date. As a result, the contractors can be affected and suffer losses due to delays that are not actually their responsibility. This study intends to evaluate project delays caused by the owner and the delay claims submitted by the contractor. This research is exploratory and uses a mixed method of quantitative and qualitative approach. Data was collected through interviews and questionnaires with 80 respondents of the construction industry. The study found five main factors causing delays caused by the owner, including: land acquisition problems, changes in design and work instructions, payment problems, and unclear drawings in the contract documents. Of these delays, the majority (93%) were claimed by contractors, with an average claim success rate of 53%, and the compensation generally in the form of extension of project completion time (63%). The most frequently chosen claim dispute settlement method (93%) is non-litigation settlement through negotiation. This research has provided a comprehensive overview of delays due to owners and the contractor claims, and gives valuable lessons for the construction industry stakeholders to cope with delays in the future.

Tujuan dilakukan penelitian ini adalah untuk mengetahui besarnya pengaruh variabel pergerakan memutar (waktu pergerakan memutar dan waktu antara dan kepadatan) di Jalan Brigjen M. Yoenoes pada tingkat keadaan terutama kecepatan rata-rata ruang kendaraan. Data yang digunakan dalam analisis ini diperoleh dari hasil survey dalam 3 hari mulai dari Pukul 07.00-18.00 WITA pada jam puncak. Dari hasil analisis dengan program SPSS 11,5 For Window diperoleh persamaan regresi untuk setiap arah lalu lintas.Untuk arah Pasar Baru-Kota :Y=31,506 + 0,380 X1 + 0.092 X2 Untuk arah Kota-Pasar Baru :Y=44,063 – 0.189 X1 + 0.97 X2. Dari nilai ini kita dapat mengetahui besarnya pengaruh yang diperoleh dari variable bebas untuk kecepatan rata-rata ruang pada arus lalu lintas menurun. Kata Kunci: Waktu pergerakan memutar, waktu antara, kepadatan

The Aesesa watershed consists of 13 sub-watersheds with varying shapes and complex characteristics. This makes the Aesesa watershed potentially prone to flooding. The purpose of this study is to identify the potential for flooding from sub-watersheds in the Aesesa watershed using the Cendana method. The data used include morphometry data, watersheds, and maps. In using the Cendana method, the input parameters taken into account are watershed area (A), main river length (L), annual maximum daily rainfall, watershed shape, river density (D), river slope (s), Nakayasu α value, channel roughness (n), curve number value (CN), and land cover. Then from the calculation of the data, value weighting will be carried out to identify flood vulnerability. The results of this study show that the weighting for 13 sub-watersheds in the Aesesa watershed is on average in the high category with a range value of 2.30 – 2.70. From this result, it is expected that mitigation and adjustment efforts can be made, especially in sub-watersheds that are already high with a weight value of 2.70 to reduce the magnitude of losses due to flooding.

The objective of this study is to analyse the affect of land use changes in the Jatigede Reservoir watershed to the inflow and sediment to the reservoir. SCS Curve Number method and HEC-HMS modeling system are used to discharge analysis. Flood discharges in the reach of Cimanuk River close to the reservoir using data of 2009 are Q2=1,751.5 m3/sec, Q5=2,280 m3/sec, Q25=3,064.5 m3/sec, Q50=3,589 m3/sec. Flood discharges in the reach of Cimanuk River close to the reservoir using data of 2018 are Q2=2,053.8 m3/sec, Q5= 2,616.7 m3/sec, Q25 = 3,439.2 m3/sec, Q50=3,984.9 m3/sec. Discharges increase in 10 years (based on 2009 data and 2018 data). For example discharge increment for Q25 is 375 m3/sec. The increment is due to the increment of CN number as the consequences of land use changes. In other words along with the time, flood discharge in the rainy season increases, however discharge in the drought season decreases.

The interaction between wind and structure in long span bridges can be investigated by numerical simulation. In this study, an aeroelastic simulation was performed on a 2 DoFs sectional model of a long-span bridge deck with free vibration techniques to analyze flutter speed and determine the effect of deck shape on flutter instability characteristics using ANSYS software. The simulation result data was then extracted using the Modified Ibrahim Time-Domain Method (MITD) identification method to obtain the damping ratio and flutter derivatives coefficients. The damping ratio value is used to determine the critical flutter speed, whereas the coefficient flutter derivatives is used to determine the characteristics of flutter instability and the flutter mechanism that occurs in the bridge. The results showed that the rectangular shape (bluff body) is more susceptible to flutter instability than the streamlined shape, and has a lower flutter speed value than the other shapes. The flutter mechanism that occurs is torsional flutter, whereas in the streamline body is coupling flutter.

Statistical validation was conducted using the Pearson Correlation Coefficient, the ratio of standard deviation of observations to RMSE (RSR), Percent Bias (PBIAS), and Mean Absolute Percentage Error (MAPE). The results show that GPM has a strong correlation with ARR (r = 0.875) and a low RSR value (RSR= 0.256), yet it exhibits a notable negative bias (PBIAS = –24.41%), indicating an underestimation of rainfall values. In contrast, simulations using ARR rainfall patterns produce peak discharges that closely match actual discharge records at the Jatigede Dam outlet, with an average deviation of less than 3% and a MAPE of 1.17%, categorized as very good. The GPM simulation produces peak discharges 13–16% higher than actual observations, with a MAPE of 14.53%, which still falls into the good category. These results suggest that while ARR provides higher accuracy, GPM remains a viable alternative source, especially in data-scarce areas, provided that appropriate calibration methods such as bias correction are applied. This study supports future research in satellite data calibration using machine learning and multivariate statistical approaches.

These volumetric changes cause swell and shrink movement in soils, which in turn will inflict severe damage to structures built above them. A Proper understanding of how the expansive soil behaves during the wetting/drying process is essential for assessing the mitigation action of expansive soil hazard and design suitable foundation. The structures that build above expansive soil bed are susceptible to heave and to withstand swell pressure, thus the swell pressure must be considered in the design. This study focuses on swelling properties of two expansive clay from Ngawi, East Java and Wates, Yogyakarta. Laboratory test on disturbed samples is used to identified and to measured swelling properties. A series of swelling test was performed under constant soil dry density. The influence of initial water content and surcharge pressure on swelling properties (i.e swell percent and swell pressure) of compacted samples were investigated. The swelling properties test used ASTM standard 4546-03 method B. It was found that the lower initial water content the higher the swell percent, but the swell pressure seems not to be affected by initial water content. At the same initial water content, swell percent decrease with the increase of surcharge pressure, but swell pressure remains unchanged.

The results were compared to other researchers’ results that conducted laboratory test and used SAP programs. The results of analysis using SAP show that the proposed model that subjected to load up to the maximum limit show similar behavior to the laboratory tests results in which parameters such as secant modulus for concrete and wall materials based on graphs of stress-strain relationships and a reduction in moment of inertia due to the crack of beam-column are taken into account. The model using LUSAS did not adopt this method instead applied plastic elastic material and non-linear analysis. The results of the analysis are still not in proportional to the magnitude of the laboratory test results, but the behavior of the load and deflection indicates similar form. The analysis models show the maximum stress points that occur on the wall similar to that with the pattern of failure in laboratory testing. The maximum stress occurs at the opening corner and the beam column joint corner that is in line with the results of laboratory testing.

Silty sand  is one of the problematic soils and often encountered in the field where the fine gradation contained in the soil allows the soil to easily deform under pressure and lateral forces. In this study, silty sand was mixed with three variations of crumb rubber content (5, 10, and 15% based on soil weight), 6% cement (based on soil weight), and 0.05% graphene oxide (based on cement weight) to measurement and analysis of physical and mechanical properties. Soil Consistency limits, compaction testing using the Proctor Apparatus, and direct shear test were carried out for each mixed variable. The test results showed that the consistency limits and dry density decreases with increasing rubber content in the soil-cement matrix containing graphene oxide. Substitution of graphene oxide into the soil-cement matrix was able to increase in the stress and shear strength of the soil at each in variation in rubber content.

The evidence is apparent in the water and soil quality exceeding water quality standard. Consequently, conflicts have arisen in the community due to failed harvests of rice and corn, impacting crops failed. The aim of this research is to restore the health of the contaminated watershed, addressing both agricultural land and water quality. The methodology in this research involves a micro watershed management approach, which includes discussion activities with the community and other parties, remediation efforts, field schools and monitoring and evaluation. The study findings suggest that the addition of organic fertilizers to restore soil fertility, particularly enhancing soil organic carbon, is crucial. This is achieved by applying 29.58 tons/ha to 30.14 tons/ha of fertilizer on the affected land. Post-remediation water quality shows values below the threshold, indicating the health of the Nglobo river basin. The results of the planting test evaluation showed that rice and corn were in good condition, as evidenced by the absence of crop failure, and the fertility of agricultural land could be restored.  Micro watershed management approach, of measurable, with real action together with the affected communities and related parties, can resolve social conflicts that occur due to pollution of community agricultural land.

However, the assessment of flexural strength in concrete frequently relies solely on a mathematical approach that several previous researchers have found. Concrete structures continue to evolve, particularly in the use of more diverse and sustainable constituent materials. Meanwhile, the generated equations use conventional concrete without adding cementitious or replacement components. Therefore, it is necessary to investigate whether these equations can accurately predict the flexural strength of concrete with diverse constituent materials. This investigation was undertaken by reviewing 72 data sets derived from the experiment by previous researchers. Each set of test data will be compared to various formulas and will also be compared to the analysis performed using Response-2000. The results show that the correlation between Response-2000 and the experiment was 0.8207 with the linear regression equation y = 1.1326x + 1.0016. The flexural strength analysis using various approach formulas resulted in an average correlation R² of 0.8246, or 82.46% correlated to the results of the flexural strength of laboratory tests.

On the other hand, the fast growing development has altered the pervious land surface of recharge area to impervious surface that reduces natural recharge. The groundwater is therefore inbalance the discharge greater than the recharge. As conssequence there is groundwater defisit, and the groundwater piezometric pressure goes down. The further impact of the lowering ground water is landsubsidence. The awareness towards the use of artificial recharge to augment ground water supplies have to be activated. Artificial recharge by using recharge wells is one of the possible measures to replenish an aquifer. The technology of recharge wells is generally well understood by both the technicians and the general population, and no special tools are needed to dig drainage wells. This research is aimed to determine and formulate the capacity of the recharge wells, both shallow and deep wells, by setting up a psysical model. The result indicated that depression curve of water table and/or piezometric pressure was logaritmic function both for shallow and deep wells. The capacity of the depends on the head, permeability, the aquifer thickness, and type of well. The capacity of the wall recharge well is higher than the last. The obtained formula gives the higher capacity value than that of dupuit. It may happen due to the deviation of the soil permeability between the measured and the actual in the test preparation

Concrete production as a construction material that commonly used in infrastructure development is one contributor to carbon dioxide (CO2) emissions. CO2 is produced from the calcination process in the manufacture of cement, burning of fossil fuels, and electrical energy used. More specifically by reviewing the calcination process on cement making, it has evaluated the consumption of cement in concrete production. The Life Cycle Assessment (LCA) is an environmental impact evaluation in terms of the life cycle of a product, wherein this paper, using the cradle-to-cradle scope, LCA is used as a method to evaluate cement consumption in concrete production to concrete waste management by taking concrete waste at Construction Laboratory and Materials Diponegoro University, Semarang for the case study. The results of the evaluation stated that the use of geopolymer concrete with fly ash as a substitute for cement could reduce up to 80% CO2 emissions with concrete strength 75% larger than conventional concrete. And for the concrete waste management, Construction Laboratory and Materials Diponegoro University reused concrete cylinder waste as a substitute material to build the retaining wall.

Alternative materials that can be used are the bamboo pile or wooden pile. The purpose of this study is to find out how much the bearing capacity of the pile is compared to concrete pile. The research was conducted using physical model tests in the laboratory. Piles with a diameter of 2 cm with different lengths are driven into the soft clay and then tested using load plates. Single pile capacity is determined from the relationship between the load and the settlement. The results showed that the capacities of bamboo and wooden piles were 1.193 and 1.086 times higher than the capacity of concrete pile, respectively. This can be caused because concrete pile has a greater weight than bamboo pile and wooden pile. The weight of the concrete increases the load, so the settlement is higher and the pile capacity is lower. Pile lengths that produce more effective capacities are obtained for piles with a minimum depth of 3/5 of the thickness of the soft clay.

Flood events occurred in 2017 at Brawijaya University campus caused by high intensity and landuse change in campus's internal and external environment. The study aims to examine performance of several empirical  formulas  in estimating rainfall intensity, investigating characteristic of each empirical formula’s contant due to varying return period (Tr), and determining appropriate Intensity Duration Frequency (IDF) curve. The formula of Sherman, Talbot, and Ishiguro was employed to obtain empirical intensity, while intensity on varying return period was calculated using Log Pearson Type III. The proposed rainfall intensity formula was selected through comparison between empirical intensity with those from observation according to criteria of relative error (KR), Nash Sutcliffe Efficiency (NSE), and Peak Weight Root Mean Square Error (PWRMSE). The Sherman formula showed best performance in estimating rainfall intensity as indicated by low value of KR and PWRMSE, followed by NSE close to one. The constant of empirical formula “a” was directly proportional with increasing of Tr; conversely, constant “b” and “n” were inverse with Tr. The validation result of Sherman formula demonstrated that the formula showed good reliability, thus recommended to estimate intensity and IDF curve in the study area.

National Road segments passing the area often experience slope failure, which causes distraction to the transportation of people and goods. Past observations showed that slope failures are related to frequent and prolonged rainfall. This paper presents the results of a numerical study on the mechanism of rainfall-induced slope failures in Pagar Alam. The study aimed to identify the critical rainfall scenario triggering slope failures. Data observation indicates that even though wet season started in October, most slope failures occurred between January and April. Thus, initial moisture is required to start the mechanism of failure. The transient pore-water pressure was assessed using SEEP/W while the slope stability was evaluated using Slope/W. The analysis showed that the critical rainfall scenario is a combination of antecedent and major rainfall. The duration of the antecedent rainfall is influenced by the slope angle.

Some opimisation may be possible in order to gain the maximum utilization of steel from one standard I- steel beam  dimension, allowing small losses due to cutting operation. In many ways, genetic algorithms, and the extension of genetic programming, offer an outstanding combination of flexibility, robustness, and simplicity. The following discussion highlights some of the key features of genetic algorithms (GAs), and illustrates an application of a particular GA in the search and estimation of global optima. Optimization may take the form of a minimization or maximization procedure. Throughout this article, optimization will refer to maximize web-opening wHile increasingthe strength and stiffness. The preference for maximization is simply intuitive: Genetic algorithms are based on evolutionary processes and Darwin's concept of natural selection. In a GA context, the objective function is usually referred to as a fitness function, and the phrase survival of the fittest implies a maximization procedure.

This study aimed to evaluate the use of xanthan gum (XG), polyvinyl alcohol (PVA), and their combination to improve the shear strength parameters of clay shale. A series of experiments were performed, starting from physical property tests, including specific gravity, gradation, and Atterberg limits, and mechanical property tests using the direct shear test to evaluate the effect of the addition of Xanthan Gum and polyvinyl alcohol or their combination on the soil parameters. Xanthan gum and polyvinyl alcohol were mixed with clay shale using dry and wet mixing methods. The study results show that adding xanthan gum and polyvinyl alcohol, and their combination, improves the plasticity index by 156%, 98%, and 6%, respectively. The modification of XG using polyvinyl alcohol was also reported to increase the cohesion and internal friction angle by 200% and 103%, respectively.

When dry season comes, farmers got the hardest hit by the limited amount of water, to where it becomes very valuable. There are two ways to solve the deficit of water during dry season. The first way is to carry out an appropriate water management, and the second one is to initiate the efficient use of water. There are other problem involving water irrigation distribution in areas that comprise several regencies, especially in down stream areas where shortage of supply of irrigation water happens. Thus, it is imperative to manage water resources and water irrigation distribution system. For example, farmer community has to hold a meeting to set a plan of water distribution. Distribution of irrigation water can be accurately determined using coefficient value of K. When K value is less than 0,50, distribution of irrigation water should be implemented using on-off (intermittent) system.Keywords: Dry season, Civilian, Farmers, Water managementPermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3418[How to cite: Supadi (2009).

The topographical condition of the Bintan is flat, which is difficult to convey water gravitate. Therefore the water management requires a storage. Fortunately some lakes were formed due to the boxit mining In Bintan. The lake area is about of  5 hectares and with 20 depth can be used as a storage for  water drinking and then distributes water using pump.  There were  two lakes identified as storage to fulfill water requirement for the west part of Bintan island. The total area of lakes is about 12 hectares and 20 m depth in average. Hydraulic structures, such as canal and water intake were design with method of “Bernoulli”. Analysis showed that the two lakes can be operated with 1 million m3 live storage and will serve 40.000 of people. Hydrological analysis showed that the dry month were occurred on February, March, Augustus and September.  Futher more those two lakes had potentially operated volume about 7 million m3 per year. As conclusion the two lakes can be used to fulfill the water requirement for the west part of Bintan Island. The location of water intake was proposed on Jago river and convey the water gravitate to the two identified lakes. Keywords: Bernoulli, Bintan Island ABSTRAK Pulau Bintan yang terletak di Propinsi Kepulauan Riau menghadapi kendala penyediaan air baku karena kondisi topografi Pulau Bintan relatif datar sehingga tidak memungkinkan pembuatan waduk yang dapat mengalirkan air secara gravitasi.  Sedangkan pemanfaatan air permukaan atau air hujan harus ditampung untuk menjamin ketersediaan air setiap saat.  Di P. Bintan terdapat beberapa danau buatan yang masing-masing luasnya dapat mencapai puluhan hektar dengan kedalaman mencapai 25 meter.  Danau tersebut dapat dipergunakan untuk menampung air yang tentu pengalirannya ke pemukiman harus menggunakan pompa. Untuk merencanakan penampungan air yang paling memungkinkan ditinjau dari aspek teknis, e.konomis maka dilakukan penelitian dan perencanaan. Terdapat dua danau di P. Bintan bagian barat yang sangat sesuai untuk tampungan air untuk penyediaan air baku Kecamatan Bintan Utara. Kedua danau tersebut yang masing masing mempunyai luas masing masning lebih kurang 10 hektar dengan kedalaman 20 m dapat disuplai dari Sungai Jago. Metodologi perhitungan pengaliran air dari sungai Jago ke kedua danau tersebut dihitung menggunakan rumus hidrolika “Bernoulli”. Hasil perhitungan menunjukan bahwa potensi kedua waduk tersebut dapat menampung lebih dari satu juta m3, yang dapat memenuhi kebutuhan air baku kecamatan Bintan Utara dengan penduduk sebanyak lebih kurang 40.000 jiwa, selama dua bulan kering yaitu bulan Februari, Maret, Agustus dan September. Hasil kajian juga menunjukkan bahwa potensi air dalam setahun lebih kurang sebesar 7 juta m3. Kesimpulan pemenuhan kebutuhan air baku untuk Pulau Bintan bagian barat dapat dipenuhi dengan memanfaatkan dua buah waduk untuk menampung air dari sungai Jago dan untuk mengalirkan air dari sungai Jago ke dua waduk tersebut dapat dilakukan dengan cara gravitasi.

Lateral torsional buckling could result in lateral deformation and torsion of section. In the AISC 360-16 Spesification, an equation is provided to calculate lateral-torsional buckling critical moment of prismatic I section beam. For cellular beams (I section beam with circular openings), AISC Design Guide 31 states that the lateral-torsional buckling critical moment should be checked in accordance with AISC Specification using gross section properties. With this assumption, thus, the design guide ignores the existence of circular opening on the web, which can cause a reduction of lateral-torsional buckling critical moment. In this study, lateral-torsional buckling analysis on cellular beam with simple support loaded by distributed transversal load has been done - the analysis utilized finite element based software. From the analysis, the critical moment is lower than AISC 360-16 critical moment with the assumption of prismatic I section beam, with the maximum difference percentage of 43,58%. Based on this study, a correction factor has been obtained to estimate the critical moment of cellular beams by using equation on AISC 360-16.

Coastal areas in Indonesia generally have drinking water problems because the well water is dry due to the dry season and the water is brackish, as is the case in Sawojajar Village in Brebes Regency, Central Java. On the other hand, the potential for rainwater in Sawojajar Village is quite good. The Brebes Regency Government is planning and implementing a rain harvesting (Gama Rain Filter) with an individual type for people who want to install rainwater harvestings in their homes, and a communal type for people who still want communal rainwater harvestings. This applied research aims to compare the two types. The individual type planning method for harvesting rain is carried out in each house and the communal type planning method is carried out in groups of houses. The planning carried out includes checking the quality and quantity of rainwater, calculating the dimensions of the storage tank, design drawings, and planning and implementation budget plans. The results of this applied research are the quality and quantity of rainwater, the design of individual and communal type rainwater harvestings, and the planning costs and implementation costs required. This research resulted in the conclusion that the individual type rain harvesting is more recommended than the communal type because the individual type costs less to plan and construct, is more flexible in placement, easier to manufacture, and maintains operations more securely.

Improper slope design and external factors such as heavy equipment loads, blasting vibrations, and groundwater may trigger instability. This study examines the stability of a disposal slope adjacent to the blasting zone at PT X Coal Mine in East Kalimantan, Indonesia. The research uses secondary data from PT X. including geotechnical parameters and operational details, Slope stability was evaluated via the Limit Equilibrium Method (Bishop and Morgenstern-Price) and Finite Element Method (FEM). Initial analyses revealed critical safety factors (FoS) of 0.853 (Bishop, Morgenstern-Price) and 0.520 (FEM), indicating high instability under combined dynamic and hydrogeological stresses. A slope redesign was proposed, improving FoS to 3.932 (dry) and 3.523 (wet) via Limit Equilibrium, and 1.570 (dry) and 1.370 (wet) via FEM. These value;s comply with the safety threshold (FoS ≥ 1.1) specified in KEPMEN ESDM No. 1827 K/30/MEM/2018, ensuring operational safety. The study underscores the necessity of integrating geotechnical and operational constraints in slope design to mitigate landslide risks in open-pit mining.

In this method, loads and stresses are calculated  based on linier elastic material and then compare them to the allowable loads and stresses. Recently, Load and Resistance Factor Design specification adopted in API RP2A – LRFD have been developed from the API RP2A – WSD using reliability based calibration. General industry practices recognise that older, existing offshore structures may not meet current design standards. However, many of these platforms that are in acceptable condition can be shown to be structutrally adequate using a risk based assesment criteria that considers platform use, location, and the consequences of failure. In this paper, a comparison study on WSD and LRFD methods in structural analysis of offshore platform is carried out by using a monopod offshore platform model. Structural analysis and unity check are performed by using SACS version 5.1 software. Keywords: working stress design, load and resistance factor design,  offshore structures

It was carried out through experimental approach and numerical analysis on six specimens of FJLB beams having a cross-section of 100 mm by 150 mm and a length of 2850 mm. The experiment was consisted of small specimen tests (BS-373:1957) and four-point bending test (EN-408) with two different cross-sectional orientations (flatwise and edgewise). The numerical analysis was performed by conducting 2-D finite element analysis developed in MATLAB program based on plane stress assumption. It was found that the average flexural capacity of beams tested under edgewise orientation was 24.6 kN, which is higher than that of the beams tested under flatwise orientation, 19.7 kN. However, the flexural stress (modulus of rupture) of those beams was about the same. All the beams experienced brittle failure caused by glueline failure between laminas or at finger joints. The results of strain measurement at mid-span of the beams throughout the test showed that the FJLB beams failed within elastic response. This finding was confirmed by the numerical analysis results.

In this study, the columns were modeled as discrete elements using ANSYS nonlinear finite element software. Concrete was modeled with 8-noded SOLID65 elements that can translate either in the x-, y-, or z-axis directions from ANSYS element library. Longitudinal and transverse steels were modeled as discrete elements using 3D-LINK8 bar elements available in the ANSYS element library. The nonlinear constitutive law of each material was also implemented in the model. The results indicate that the stress-strain relationships obtained from the analytical model using ANSYS are in good agreement with the experimental data. This has been confirmed with the insignificant difference between the analytical and experimental, i.e. 1.011 and 1.306 percent for the peak stress and the strain at the peak stress, respectively. The comparison shows that the ANSYS nonlinear finite element program is capable of modeling and predicting the actual nonlinear behavior of confined concrete column under axial loading. The actual stress-strain relationship, the strength gain and ductility improvement have also been confirmed to be satisfactorily.

Albeit the road section's slope has previously been strengthened with bored pile reinforcement, the slope continues to move. This study's objective is to examine slope stability by considering earthquake loads and to suggest improvements for efficient slope reinforcement. Slope stability analysis utilizing PLAXIS 2D program based on the finite element method and DMT-KD Method which is the result of field testing using the Flat Dilatometer Test (DMT)). PLAXIS modeling results show that the slope failure line is deeper below the bored pile reinforcement. The results of the analysis using DMT-KD method showed similar slope failure, the conclusion is DMT-KD method can be the initial basis for slope stability analysis on mudstone. The PLAXIS modeling results obtained a static safety factor of 1.113 and a safety factor due to an earthquake of <1, both of which fall short of the requirements of minimum of 1.5 for static loads and 1.4 for earthquake loads. The body of the road develops cracked as a result of this issue. Additional reinforcement modeling is carried out using bored piles and gabions. As shown in the results of additional reinforcement modeling, bored pile reinforcement that reaches below the slope failure line is more successful than gabion reinforcement at the slope's base in raising the safety factor.

This mixture containing Reclaimed Asphalt Pavement (RAP) and Reclaimed Aggregate Materials (RAM) and stabilized with portland cement as pavement structural base layer. This technique has been applied in the field in some pavement major rehabilitationand reconstruction projects successfully. However, identical to other cementitious stabilized materials, this CTRB material is prone to cracks during service. For that reason, the use of cement as a stabilized material in CTRB has to be reviewed thoroughly before implementation in the field. The use of recyclable materials in pavement applications is not only environmentally friendly, but also can reduce the cost of materials in a particular project. In addition, a reduction in the use of cement in the CTRB material has a potential to reduce anticipated cracks that influence the physical characteristic of the mixtures. In this research project, the Indirect Tensile Strength (ITS) Test was conducted to review the influence of partial cement replacement with natural pozzolan (trass) to the mechanical properties of the CTRB to withstand tensile stress. A lower ITS value correlates to the shrinkage cracking tendency of the material. The results show that the increase in the percentage of cement replacement correlates well to the increase of the ITS values. Direct correlations exist for 15% and 30% cement replacement of the 4% to 6% CTRB cement content with 40% RAP-60% RAM and 60% RAP – 40% RAM combinations.

The Pemali-Juana River Basin Center has planned the construction of a rubber weir which will be built in 2022-2024 to overcome this problem. It is hoped that this rubber weir will be a solution for controlling floods and as a water storage system during the dry season. This research aims to model the hydraulic characteristics of the flow in Karet Juwana Dam under flood conditions (Q10, 20, 25, 50, and 100 years). Modeling of flow hydraulic characteristics using HEC-RAS 5.0.3 software. The modeling results show that when the rubber weir expands, maximum backwater occurs for 2.26 km upstream of the weir. The water level above the rubber weir is 1.0 meters with flow speeds upstream and downstream of the weir threshold of 0.40 m/s and 0.66 m/s respectively. Controlling flood levels against overtopping can be optimal if the water level is 0.60 meters above the crest. Hydraulically, the simulation results show that a deflation speed of 0.2 meters/minute can control overtopping optimally.

The prestressed concrete dimension cross sections normally are fixed, provided by the factory based on their experience for every span length. However, this size aspect can be developed to make better improvement. In this study, I and box girder shapes were modified with the same total cross-sectional area. Three types of modification have been made for each girder shape by giving the space on the middle for I girder and changing form from trapezoidal to rectangular section for box girder. The number of steel tendons for this research was made typically and same so that the stress and displacement can be compared fairly. Manual calculation was performed for all samples and was completed under three circumstances namely initial condition, loading condition, and final condition. Also, the manual calculation is according to Indonesian provisions, which are SNI 2833-2016 for the earthquake load and SNI 1725-2016 for normal loading on bridges. From the result, it is known that one shape for each girder shape has met the criteria for the smallest stress and displacement.

Berbagai serat sebagai bahan dasarnya telah dikembangkan seperti serat karbon, serat gelass dan serat aramid. Diantara sekian jenis FRP, salah satu yang memiliki sifat-sifat mekanis yang baik adalah FRP dengan bahan dasar serat karbon yang dikenal dengna nama Carbon Fiber Reinforced Plastics (CFRP). Saat ini ada berbagai jenis CFRP yang telah di produksi. Berdasarkan serangkaian pengujian, kegagalan suatu material CFRP dimulai dari terjadinya kegagalan geser (slip) antara serat dengan bahan plastiknya (bahan polimer) sehingga menimbulkan retakan-retakan mikro yang pada akhirnya menyebabkan konsentrasi tegangan. Untuk meningkatkan kapasitas geser (rekatan), maka telah dikembangkan CFRP yang dalam proses produksinya terlebih dahulu diberi tegangan awal (initial force). Hasil analisa menunjukkan bahwa dengan mentrasfer tegangan awal yang diberikan menyebabkan timbulnya tegangan radial disepanjang batang CFRP yang dapat meningkatkan kapasitas rekatan geser antara serat-serat dengan bahan plastic (resin matriks).Keywords: CFRP, radial stress, reinforcement, stress, concrete structurePermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3936[How to cite: Djamaluddin, R. 2006, Analitycal Study of the Radially Stress Due to Initial Tensile Force in Manufacturing of CFRP, Jurnal Media Komunikasi Teknik Sipil, Volume 14, Nomor 1, pp. 73-77]

The high sulfate content in these environments poses a threat to the durability and compressive strength of concrete. The impact of sulfate attack on concrete can result in degradation and a decrease in concrete quality. Several methods have been used to maintain the durability of concrete, such as applying coatings to the surface of the concrete or using pozzolanic materials in the concrete mixture. In this study, Fly Ash was used as a pozzolanic material to reduce the impact of sulfate attack on concrete. The experiment involved adding Fly Ash to the concrete mixture in proportions of 0%, 10%, 20%, 30%, 40%, and 50% by weight of cement. Three test specimens were made for each variation in diameter and height of 10 cm and 20 cm, respectively. The durability test of the concrete used a magnesium sulfate (MgSO4) solution with a dry-wet cycle method according to SNI 3407-2008, which was conducted after curing in water for 28 days. The results of the test showed that adding Fly Ash to the concrete mixture has been proven to reduce damage and minimize the degradation of concrete quality due to sulfate attack compared to normal concrete without the use of Fly Ash. The use of Fly Ash also increased the compressive strength of all test specimens compared to normal concrete without Fly Ash.

This is due to the rural characteristics of the area, where land has been converted from forest to agricultural land and settlements. This condition causes rainwater cannot infiltrate into the ground, thereby increasing runoff and reducing groundwater reserves. Therefore, the concept of Water Sensitive Urban Design (WSUD) is applied to this location to reduce the risk of water disasters. One of the WSUD technologies that can be applied is the permeable paving block system. This system can help infiltrate water to the ground thereby reducing runoff that causes flooding and storing water to replenish groundwater reserves. The design is planned in the pilot area of Jotangan and Krikilan Villages, Bayat District by applying a partial exfiltration pavement system. The structural design of the pavement layers is in the form of a permeable paving block with a compressive strength of 21.29 MPa with a thickness of 10 cm, a bedding layer of 6 cm, an open-graded base of 18 cm, and a drain pipe with a capacity of 3,78 mm/hour. The permeable paving block system in the WSUD pilot area can reduce runoff by 62.64%.

Indeed, natural damage to road construction is unavoidable but it becomes a problem if the damage occurs not long after the road product is handed over to the road manager or the government. Then the next question can arise whether the phenomenon of early pavement damage will cause harm to both road users and the government.This study aims to show the thinking framework of financial consequences and apply it through a model due to the occurrence of premature damage. Referring to the concept of benefit value that is represented by road conditions over the life of the service, then roads that have been damaged before their construction ends will result in losses due to loss of benefits. Based on this concept, a simulation was conducted using a national road data. Simulation results show that there is an estimated financial loss due to the occurrence of early damage. For early damage with a condition value of loss of 36 then the estimated loss is Rp 458,257,899.41 per kilometer. Estimated average loss per kilometer for each loss of one unit of condition value is Rp 12,72,386.09. The results of this study also show that roads that do not suffer early damage do not cause losses or losses are zero.

Hal ini untuk melihat apakah perilaku deformasi sesuai dengan kondisi yang ada di lapangan, sehingga penelitian ini mengambil judul analisa balik kelongsoran. Bidang longsor dari hasil analisa dengan Plaxis menunjukkan saat tidak hujan (muka air tanah) jauh dari permukaan bidang tanah angka keamanan (Safety factor) nya lebih dari satu yaitu SF = 1.063, tetapi harga ini mengindikasikan bahwa kondisi tanah yang ada sudah kritis, dengan memperhatikan SF nya yang mendekati nilai 1, ketika muka air tanah naik dengan anggapan terjadi hujan yang mengakibatkan kondisi tanah menjadi semakin jenuh safety factor nya berkurang, SF = 0.873 yang mengakibatkan terjadi longsor. Terlihat juga bahwa tanah yang cenderung longsor adalah tanah pada Lapisan 1 (dengan bidang longsor antara lapisan 1 dan lapisan 2) yaitu lapisan tanah yang mengalami pelapukan (tanah residual), sedang lapisan 2 maupun lapisan 3 tidak terdeformasi. Kesimpulan yang dapat diambil dari penelitian ini adalah: Model deformasi yang di dapatkan dari hasil Plaxis, mempunyai kecenderungan yang sama dengan kondisi deformasi yang terjadi di lapangan sedangkan letak bidang longsor dengan Plaxis, menunjukkan bidang longsor yang menyerupai kondisi di lapangan. Kondisi semua lapisan tanah yang jenuh oleh air tanah pada lokasi, terancam longsor.

Damage can be in the form of change on the concrete surface or loss of concrete quality. To be able to identify the concrete damage condition on a building, inspection and assessment is required. Visual assessment is a method that can be a good first step to identifying the concrete damage condition on a building structure. Visual assessment is limited to concrete surface that can be accessed with visual senses. The goal of the research is to develop the concrete damage assessment method on a building visually that can be accepted by construction industry users in Indonesia with the Soft System Methodology (SSM) approach. Application of the SSM approach in this research uses the Root Definition component, CATWOE analysis, Rich Picture, and Conceptual Model. Result that is obtained from research, is the development concept for a visual method of building damage assessment, based on the seven steps according to SSM.

Consequently, the bamboo reinforcement and concrete used to have slip and failure to composited, this make the concrete and bamboo working independently to sustain the given loading and the bond failure become the main issue than the beam failure. This research studied about the role of the pivot hooks that capable to enhance the loading capacity higher than the beams without the pivot hooks. Experimental test performed in order to identify the effect of the pivot hooks presence which added to the flexural reinforcement which made by bamboo materials to avoid the bond slip failure that mostly occur in the bamboo reinforced concrete beams. The experimental test which verified by the numerical analysis by FEA NX commercial software proof that the pivot hooks are able to increase the loading capacity of a concrete beam 33% - 40% higher than the bamboo reinforcement without the pivot hooks. Architectural façade and budget efficiency caused the bamboo become unavoidable material in construction, by adding the structure modification such as the pivot hooks for the bamboo reinforcement, the failure can be reduced, then the entanglement of bamboo in construction become more functional.

Building protective beaches that can meet these objectives include low threshold breakwaters (submerged breakwater). Some of the excessuse of low threshold breakwaters are: 1. No disturbing beauty of the beach; 2. because construction is under water, then when the wave comes partially absorbed wave energy, will be partially reflected, and the rest will be transmitted; 3. can become breeding grounds for fish, because the construction is hollow. The disadvantages are: 1. requires a large stone with a large number, 2. in the assembly requires a supporting infrastructure such as transport  equipment, long bridge, lifting equipment etc, thus requiring a lot of cost. Based on that research conducted by the title of the transmission and reflection of waves on double sumerged breakwater. Methodology of research, conducted with with physical models, and then continued with theoretical studies in order to obtain the equation for calculating the coefficient of wave  transmission and wave reflection coefficient. The results showed that to calculate the magnitude of the coefficient of wave transmission and wave reflection coefficient can be approximated by the following equation: , .

Considering its short planting years and sustainable production, Sengon wood is very potential to be used as construction materials of low-rise houses to support the housing needs in Indonesia. Creep behaviour of LVL Sengon material is one of the mechanical properties that needs to be considered. This article evaluated value of creep factor of the open web truss joist (OWTJ) LVL Sengon test and compared this experimental creep factor with the numerical results developed by FE model taking into account the viscoelastic parameters of authors' previous study. The viscoelastic parameters were based on a 217-day creep test of compression and tension parallel to the grain of LVL Sengon at 20 % of stress level that were further modeled using Prony series creep model having n equals to 3. The reduction in the modulus of elasticity over time resulted in creep deflection and creep factor values at 217 days of testing results and FE numerical analysis of the OWTJ LVL Sengon ranging from 1.50–1.54; while the predicted creep factor at 25 years of service life is 1.57 or greater than the creep factor value provided in SNI 7973: 2013 of 1.5.

In Indonesia, usually it is very difficult to get a complete and appropriate data on hydrology at certain locations. To cope with the constrains and lack of data on hydrology as is mentioned above, experts on hydrology tend to solve the problems with the following methods: Stochastic analysis, Correlation and regressions analysis, and Simulation analysis on the watershed. In this paper, the phenomenon of the distribution of annual rainfall to monthly rainfall will be discussed utilizing stochastic analysis (i.e. temporal disagregation model), by presserving their statistical characteristics. The output of this model, which is quite reliable and can be use, among other, as a sound base for development of water resources and flood control.Permalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3926[How to cite: Wahyuni, S.E., 2005, Distribusi Data Tahunan Menjadi Data Bulanan, Jurnal Media Komunikasi Teknik Sipil, Volume 13, Nomor 3, pp. 106-116]

Similar with other types of cement-based materials, SCC also has a brittle characteristic. This problem can be encountered by adding fibers in to the concrete mix. Unlike its effects to hardened concrete, the presence of fibers in concrete mixes can cause significant deterioration to the concrete workability. This research was conducted to investigate effects of polypropylene fiber addition on four key characteristics of SCC in the fresh state. In this research, concrete mixes were prepared containing 0, 0.05, 0.10, and 0.15 percent volume fraction of polypropylene fibers. Fresh properties were evaluated based on its passing ability, flowability, viscosity, and segregation resistance using J-ring, Slump flow, and Sieve Segregation Resistance tests. Test results indicate polypropylene fibers reduce flowability and passing ability but will increase viscosity and segregation ratio of SCC. Furthermore, it can be concluded that polypropylene fiber reduce deformability of SCC in the fresh state. It can be suggested that polypropylene fibers allowed to be added into SCC mixes up to 0.10 percent by volume of concrete.

This experiment of the Kübler wood connector is done to the three types of the hard wood such as Bangkirai (Shorea Lacvifolia Endert), Simantok (Shorea spec.div) and Merbau (Intsia spec.div), and also the wood that will be connected as the tested supporting specimen is Ulin wood (Eusyderoxylon Zwageri). Every tested specimen is applied the centric compressive axial load in the straight joint, connection with an angle of 120° and connection with an angle of 90° until the connection reaches the failure strength. From the experimental result, it is obtained that on the straight joint, Merbau wood (Class II) having average and characteristic failure strength more than of its Simantok wood (Class II)  and  Bangkirai wood (Class I). For the angle connection using Simantok  wood, the value of its characteristic failure strength is getting higher if the angle of the connection more than 90o, but not for the shifting. Compare with the theoretical value, actually the characteristic failure strength value of Merbau wood is more than the permissible strength, but not for its of  Bangkirai and Simantok  wood.Keywords: Kübler wood  connector, wood connectionPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3894[How to cite: Tjitradi, D., 2005, Pasak Kayu Kubler Sebagai Alternatif Alat Penyambung pada Konstruksi Kayu di Kalimantan Selatan, Jurnal Media Komunikasi Teknik Sipil, Volume 13, Nomor 1, pp. 27-38]

The effort to overcome the problem has been carried out, amongst other is to cover with blanket namely fire proofing. This research is to conduct the characteristics of concrete slabs under fire exposure. Eight samples were cast with concrete having compressive strength of 52,68 MPa and were reinforced with high-strength steel having yield stress of 600 MPa. The samples which were of 60 mm thick, 600 mm wide and 1200 mm long, were equipped with reinforcement at 10 mm deep. Eight of samples were grouped into 2 samples each to represent 4 group. Each group represents the reference (type I), the ones with thicker concrete cover (type II), the ones with additional mortar cover (type III), and the ones with fire proofing product (type IV).  Fire tests were conducted through all groups. and the test procedure follows the ASTM E119-88.  The fire exposure was done in 30 minutes and the equivalent live load of 345 kg/m² was provided during the fire tests. Three thermocouples were also employed at different levels of depth of concrete to monitor the heat transfer in the high strength concrete and one thermocouple was used for monitoring furnace temperature. The experiment shows that the application of fire proofing product is much more efficient in reducing heat of concrete surfases. The reductions of temperature for slab type II, III, and IV are of 56,44%, 68,145%, and 85,14%. respectively. Crack spreads more evenly in the slab of  type I and II. Explosive spalling happens more at the reference slab in comparison to the slab with thicker concrete cover. The deflections of slab of type I, II, III, and IV after fire exposure are of 315,92%, 319,52%, 240,84% and 73,96% in comparison to maksimum deflections.Keywords: crack, spalling, high-strength concrete, fire proofingPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3917[How to cite: Sulistyawati, R., 2005, Pengaruh Fire Proofing pada Perilaku Pelat  Beton Mutu Tinggi Saat Terbakar, Jurnal Media Komunikasi Teknik Sipil, Volume 13, Nomor 3, pp. 1-12]

Based on data from KAI DAOP 4 Semarang, there were 12 accidents at level crossingsin 2023, while in 2024, the number increased to 26, indicating a rise in accident rates. One accident that wentviral on social media occurred in Semarang in 2023, involving a low-bed trailer that got stuck at a levelcrossing. The objective of this study is to analyze and evaluate level crossings, assess their compliance withregulations, and provide recommendations for improvements. This research employs the triangulation method,utilizing data obtained from geometric surveys and an inventory of crossing equipment. The study focuses onlevel-crossing locations JPL 6 Madukoro and JPL 5 Kaligawe in Semarang City. The findings indicate that theexisting conditions do not fully comply with regulatory requirements in terms of facilities and geometricspecifications. Specifically, the Madukoro crossing is constructed at a higher elevation than the surroundingtopography, creating a hump with a height of 86 cm above the road surface and a grade of 12.8%. Thiscondition increases the risk of long vehicles, such as low-bed trailers, getting stuck, potentially leading tosevere accidents. Therefore, it is recommended that regulations concerning level crossings be reviewed andrevised.

One such parameter is the variation of wave period. The influence of wave period variations on the performance of physical model of the wave energy converters have been investigated at the Hydraulics Laboratory, Department of Civil Engineering, Hasanuddin University Indonesia. This WEC physical model was fabricated and assembled at Politeknik ATI Makassar Indonesia. The investigation steps consists of physical model development, physical model investigation at wave flume prior to the wave period  variation, measuring input output parameters of the physical model under test and empirical model formulation based on observed data analysis. Physical model test carried out on the wave flume at the Hydraulics Laboratory of the Department of Civil Hasanuddin University, at a water depth of 25 cm, wave height between 5-9 cm and wave period between 1.2 - 2.2 seconds. Investigation result based on flywheel radial speed (RPM) and torque (Nm) indicated that calculated harvested power was inversely proportional with the wave period. The longer the period of the waves, the energy produced is getting smaller. The derived empirical formula was y = -85.598x + 208.53 and R² = 0.8881. Y is energy produced (Watt) and X is the wave period (Second). Formulations generated from this study could be used as a reference for future research in dealing with wave period variations on a design one way gear wave energy converter as a source of renewable energy.

Kosambi District in Tangerang Regency is one of the rapidly growing coastal regions due to its proximity to Soekarno–Hatta International Airport. However, the area is predominantly underlain by soft marine clay soils with low bearing capacity and high compressibility, which pose challenges for infrastructure development. To improve soil stability, soil stabilization methods are required to enhance unconfined compressive strength and undrained shear strength. This study aims to analyze the effect of cockle shell powder addition on the unconfined compressive strength and undrained shear strength of soft marine clay. Laboratory tests were conducted on untreated soil and soil stabilized with 5%, 10%, 15%, and 20% cockle shell powder by dry weight of soil. The results indicate that the optimum performance was achieved at a 10% addition, resulting in a 24.86% increase in unconfined compressive strength compared to untreated soil. In addition to improving strength, the addition of cockle shell powder reduced water content and enhanced interparticle bonding, thereby improving soil stability. These findings demonstrate that cockle shell powder has strong potential as an effective stabilizing material for soft coastal clay soils.

Therefore, this research is conducted to determine the stability of river bank due to tides with numerical analysis. The numerical analysis method was done by 2D Plaxis Software that using the Finite Element Method. The analysis was conducted on a homogeneous slope with 2 (two) different soil permeability coefficient values, there are low permeability and high permeability. The analysis is modeled by fully coupled analysis between deformation and ground water flow analysis. The results of the analysis indicate that a tidal are influence the stability of the slope based on the safety factor value. The highest of safety factor value are shown in high tide condition, and the lowest occur at low tide condition. This happens because the high tide condition occur the addition of hydraulic pressure from the water that will resist the sliding, while the low tide condition will reduce the hydraulic pressure. This can be a concern to the stability of river bank with tidal condition in order to avoid the erosion during the low tide conditions. The comparison of safety factors between two different types of soil permeability are not significant, the difference are only 3%.

However, many empirical equations used to predict properties of concrete or design structure members are based on test using concrete with compressive strength less than 41 MPa. Applicability of this design equation for high strength concrete structures may lead to conservative or even unsafe design. One such example is the provision for calculating development length of reinforcing bars which is developed based on bond capacity of steel bars embedded in concrete.The research study was motivated by the lack of test data on bond performance of reinforcing bars embedded in high strength concrete especially those related to high-strength fly-ash concrete. More than 35 specimens with various concrete compressive strength fc¢ and bar diameter (deformed and smooth bar) were tested. The result of this experimental shows that bond equation from ACI is too conservative for high strength concrete structures.

Reducing cement in construction is believed to be the solution for better environment. Portland pozzolan cement (PPC) is known as a more environmentally friendly cement which substitutes some portion of cement clinkers with pozzolanic materials such as fly ash. Another material which is considered as green material is Geopolymer. The purpose of this study is to investigate the durability of mortars made of PPC and geopolymer in the corrosive environment. The geopolymer mortar was made of fly ash with 25% white soil substitution, and also 8M NaOH and Na2SiO3 as activators. The corrosive condition was simulated by Sulfuric Acid solution (H2SO4) with a pH of 4. The durability of the two types of mortar was investigated by testing their compressive strength, direct tensile strength, porosity, density and the changes of mass and physical shapes after immersion. The results show that the immersion of the mortars in a solution of pH 4 sulfuric acid does not make any major effects on the performance of the PPC mortar. However, the performance of geopolymer mortar with 25% white soil substitution decreases after being immersed in sulfuric acid solution.

Keywords : Hydrologic area,Drainage, Topographic, Hydrology analysis, Flood discharge .   Abstrak   Masalah banjir merupakan masalah kompleks. Dalam pengamanan banjir, harus memperhatikan aliran air sebagai satu sistem wilayah hidrologis. Banjir di Jakarta selalu terjadi setiap musim hujan pada bulan Januari sampai Maret. Kota Administrasi Jakarta Barat yang merupakan salah satu dari lima kota administrasi di wilayah DKI Jakarta, juga sering dilanda banjir, dibeberapa kawasan tinggi genangan banjir mencapai 1-3 meter. Dari hasil kajian tata air kawasan Rawa Buaya, disimpulkan masalah tata air di Rawa Buata yaitu kurang adanya kesinergisan antara saluran makro dengan saluran sub makro dan mikro yang masing-masing kewenangannya berbeda. Kondisi drainase kawasan rawa Buaya sebagian besar secara konstruksi dalam kondisi cukup baik. Permasalahannya adalah banyak terdapat sampah, sedimentasi, kondisi pintu air yang tidak berfungsi dengan baik dan ada beberapa saluran yang terputus, serta kondisi tata guna lahan yang belum sesuai dengan RTRW2010. Hal yang berpengaruh besar adalah kondisi topografi kawasan Rawa Buaya yang rata-rata pada topografi rendah.

Up to the moment the solution of this problem is by doing trade-off between the time and the cost. With this procedure, usually the completion time can be accelerated, but the increase in construction cost is unavoidable. It is described in this paper a method to accelerate the completion time of activities in the critical patch, so that the completion time can be kept as planned, but the construction cost does not increase. One of the efforts carried out here is by developing the fast-track method on critical activities with a modification of CPM model scheduling, and it is for case of construction of middle-class housing in Malang, East Java. The methods applied were site observation in the construction time and cost of the critical activities, and interview with the site manager as well as the supervisor. The data was processed non-statistically. The results obtained prove that the developed fast-track method here gives an advantage in time saving of 34% from the completion time in general and cost saving of 2.45%. Keywords: Time saving, cost reduction, CPM model, fast-track, middle-class housing. ABSTRAK Biaya pembangunan rumah menengah di Indonesia cenderung membengkak, terutama jika terjadi keterlambatan waktu penyelesaian aktifitas-aktifitas pada lintasan kritis. Hingga kini cara yang digunakan untuk mengatasi masalah ini adalah dengan melakukan trade-off antara waktu dan biaya. Dengan cara itu, umumnya percepatan waktu penyelesaian dapat dilakukan, tetapi pembengkakan biaya pembangunan tidak terelakkan. Diuraikan dalam tulisan ini cara percepatan waktu pelaksanaan pada aktifitas di lintasan kritis agar waktu penyelesaian dapat dicapai sesuai rencana, tetapi biaya pembangunan tidak membengkak. Salah satu upaya yang dilakukan di sini adalah melakukan pengembangan metode fast-track pada aktifitas di lintasan kritis dengan modifikasi penjadwalan model CPM, dan untuk kasusnya adalah pada pembangunan rumah menengah di Malang, Jawa Timur. Metode yang digunakan adalah observasi lapangan terhadap waktu dan biaya pelaksanaan aktifitas pada lintasan kritis, dan wawancara dengan Site Manager serta Pengawas Lapangan. Data diolah secara non-statistik. Hasil yang diperoleh membuktikan bahwa pengembangan metode fast-track seperti ini memberikan keuntungan berupa penghematan waktu sebesar 34% dari waktu yang umumnya dibutuhkan dan penghematan biaya sebesar 2,45%.

The purpose of this research is to assess the extent of the influence of jute fiber as a reinforcing material in enhancing the cohesive and tensile strength of asphalt concrete mixtures, particularly in response to temperature changes. This research was conducted using an experimental method in the laboratory, employing jute fiber based on an optimum percentage of 0.6%, with a length of 8 mm, and tested under various temperature conditions. The test results indicate that asphalt concrete mixture reinforced with jute fiber (DP) has a total deformation of 1.09 mm at a testing temperature of 40°C. Its deformation rate is 0.0033 mm/minute, which is smaller compared to the asphalt concrete mixture without jute fiber (TS) with a total deformation of 1.19 mm and a deformation rate of 0.0040 mm/minute at the same temperature. At 60°C, the asphalt concrete mixture with jute fiber (DP) shows a total deformation of 1.83 mm with a deformation rate of 0.0107 mm/minute, while without jute fiber, the total deformation is 2.00 mm with a deformation rate of 0.0113 mm/minute. In the results, the indirect tensile strength of the asphalt concrete mixture without using palm fiber was lower, the stiffness of the mixture was lower than that of using palm fiber and decreased linearly with increasing temperature.

Penanggulangan yang telah ditempuh selama ini adalah dengan cara membangun bangunan pengendali sediment atau bangunan sabo yang ditujukan untuk mengurangi besarnya daya perusak tersebut dengan cara menahan laju aliran sediment yang mengalir ke hilir. Dalam hal suplai sedimen dari gunung berapi tersebut relative besar maka kehadiran bangunan sabo terlihat nyata manfaatnya. Namun pada saat dimana suplai sedimen berkurang, maka kehadiran bangunan sabo sering dinilai sebagai penyebab utama terjadinya degradasai dasar sungai di ruas-ruas sungai sebelah hilir bangunan sabo. Paper ini membahas hasil studi tentang efektivitas suatu bangunan pengalihan sedimen (sediment bypass), dalam rangka mengurangi besarnya suplai sedimen yang masuk pada suatu sungai,  yang kemudian dialihkan pada sungai yang lain. Studi dilakukan dengan mengambil kasus Kali Boyong dan Kali Kuning yang berhulu di puncak Gunung Merapi, Daerah Istimewa Yogyakarta. Teori pendekatan imbangan sedimen diaplikasikan pada suatu geometri bangunan pengalihan, yang selanjutnya diperbandingkan dengan hasil pengujian model fisik. Hasil studi menunjukkan bahwa aplikasi persamaan imbangan air (konservasi massa) pada bangunan pengalihan sedimen mempunyai nilai yang mendekati dengan hasil yang diperoleh dari pengujian model fisik.

In addition, engineering behaviour of bagasse ash can be improved by addition of cement containing high calcium. Recently, research about cement stabilized soil is continuously in progress. In this paper, a set of experiment programs were done to investigate the randomly oriented polyester fibre  inclusion in bagasse ash-cement stabilized soil.  Bagasse ash was mixed with clay in different proportions. To get the optimum curing period,  it was done light compaction test of soil with 8% cement cured with 7, 14, 21, 28 and 36 days curing period,  that was found on 28 days. The next experiment was compaction test on soil + 8% cement + 3,6,9 and 12% bagasse ash to obtain optimum bagasse ash proportion. The result indicated that optimum bagasse ash content was 9%. To ensure this result, unconfined compression test was done on the same sample. Finally, light compaction, unconfined compression and direct shear tests were done on : soil + 8% cement + 9% bagasse ash +  polyester fibre with 28 days curing period. The results showed that maximum dry density and optimum moisture content was not influenced by fibre inclusion, whereas the increase of shear strength of stabilized soil with fibre inclusion  was mainly due to improvement of internal friction angle. In unconfined compression test, the unconfined compression strength of stabilized soil was significantly improved by fibre inclusion.

This paper aim is to analyze the model of compressive stress-strain curve of recycled aggregate concretes based on the literature review using the statistical approach. Database of existing experimental tests from different researchers consists 124 test specimens that come from 25 previous published journal articles. The specimens was selected based on the proportion of RCA mixtures that been used which are 50% and 100% of the concrete aggregates. This research was using simple linear regression analysis method with Statistical Package for The Social Sciences (SPSS) software. The data of the specimen analysis was differentiated into three stages of analysis, namely the analysis for the whole group data specimens, the group of concrete specimens without any additives, and specimens that use additives. The results show that the significant value from the data analysis was lower than 0.05, which are the limit values for significant value of the data analysis. This means that the water-cement ratio has the influence to the compressive strength of RCA concrete mix.

The erosion index is defined as the total soil loss divided by the tolerable soil loss. The life of a reservoir is affected by the amount of sediment flowing into the reservoir and sediment trap, which is a function of the effective capacity of the reservoir and the inflowing water. Soil and Water Assessment Tool (SWAT) version 2005 model was incorporated into this study to simulate hydrological processes taking place in the catchment. ArcSWAT (ArcGIS Interface for SWAT 2005) program was used as a preprocessing tool to write in input files to be executed by SWAT.SWAT model involves a great number of parameters. Hence, its reliability depends so much on the data availability and some parameter adjustments. From the calibration and validation results on annual data, the model is considerably of good performance. This was proven from the coefficient of correlation (r), coefficient of determination (R2), model efficiency (ME), and index of agreement (IA) which are close to 1 except for the sediment inflow. The difference between the observed and simulated sediment inflow resulted because the SWAT model accounts for the annual variation in precipitation and mean inflow discharge which is not manifested in the observed data. The modeling results revealed that the average inflowing sediment into the reservoir is 5,102,000 ton/year resulting in 46.18 year effective life of the reservoir which corresponds to the critical degree of 1.15. The graph plotting the values of the sediment inflow and the critical degree of the reservoir life reveals a linear relationship.

One of the most popular reinforcement methods today is using a corrosion resistant Glass Fiber Reinforced Polymer (GFRP) material. This study was conducted to investigate the behavior of GFRP-S rectifying capacity in reinforced concrete beam reinforcement in 1, 3, 6, and 12 months. The test specimens consist of 10 reinforced beams with dimensions (15x20x330) cm that has been reinforced with GFRP-S in the bending area. Beams without immersion symbolized B0, immersion 1, 3, 6, and 12 months each given symbols B1, B3, B6 and B12. The test specimen is loaded statically until it fails. To record the data when testing is installed strain gauge and LVDT. From the result of the research, it can be seen that there is a decrease of GFRP-S rectification capacity in the test specimen after soaking in seawater. The value of the decrease in the capacity of the bonding can be predicted by using the equation

Umumnya plastik berbentuk pelet sehingga untuk mencampur dengan aspal diperlukan tambahan alat. Peralatan ini tidak selalu tersedia disetiap kota atau Unit Pencampur Aspal. Oleh karena itu perlu dicari solusinya yaitu bagaimana menambahkan polimer tanpa tambahan peralatan. Penambahan polimer untuk menaikkan mutu campuran beraspal ada dua cara, yaitu cara basah (wet process) dimana plastik ditambahkan ke dalam aspal panas dan dicampur hingga homogen dan cara kering dimana plastik ditambahkan ke dalam agregat panas. Tujuan dari penelitian ini adalah untuk membandingkan pengaruh kedua cara pencampuran plastik mutu rendah jenis LDPE terhadap kinerja campuran beraspal pada kadar aspal optimum, yang sama dengan kadar aspal optimum hasil pengujian Marshall aspal pen 60 sebagai pembanding (balnko), sedangkan kadar plastik adalah 3,5% terhadap berat aspal yang diambil dari hasil pengujian variasi kadar plastik terhadap mutu aspal yang telah dimodifikasi dengan plastik (cara basah). Pada cara kering plastik dengan kadar sama dengan cara basah ditambahkan kedalam agregat panas (pada temperatur campuran) dan diaduk selama 30-45 detik. Dari hasil yang diperoleh di laboratorium menunjukkan cara kering menghasilkan karakteristik Marshall, Stabilitas Dinamis dan Resilien Modulus lebih besar dari aspal pen 60, namun lebih rendah dari cara basah. Dari segi ekonomi cara kering diperkirakan lebih murah karena waktu pencampuran lebih cepat,  tidak memerlukan alat pengaduk (mixer) dan lebih mudah di handle dari pada cara basah.Kata kunci: Aspal, cara kering, cara basah, Kadar aspal optimum, polimer, kinerja campuran beraspalPermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3695[How to cite: Suroso, T.W.

The problem is that many travelers prefer to use private vehicles rather than public transportation. This study aims to analyze the sensitivity of the mode selection model which explains the probability of choosing a BRT against aprivate vehicles if a BRT is presented in the Central Business District of Pontianak City. The mode selection method uses the Stated Preferences Technique in the form of a quetionnaire which is analyzed by multiple linear regression to obtain a utility equation. Based on the results of the sensitivity analysis of the mode selection model, the probability value of selecting BRT is 21,7%, if it is in conditions where the difference in the attributes offacilities and comfort (X1) is -10, this means that there are no facilities and conveniences of BRTsuch as private vehicles, thesecond is the difference in  thewaiting time attribute (X2) which is 15 minutes, the third condition is the difference in travel costs attribute (X3) namely Rp 0,- and the fourth condition is the difference in travel time attribute (X4), which is 10 minutes To increase the probability of choosing a BRT to 60%, it can be done by increasing the difference between the facilities and comfort attributes to 0 (zero), which means there is no difference in facilities and comfort that BRT has with private vehicles such as the availability of air conditioning, free WIFI, clean, fragrant, having a bag storage area  and others. This is because the most sensitive attributes compared to other attributes are facilities and comfort attributes.

Hydropower might be promising; however, its production is highly affected by seasonal variability. Matenggeng dam is designed as multipurpose dam, namely for supplying the irrigation system, flood control, and utilization in a hydropower system. Based on its design report, the Matenggeng Dam is planned to produce power of about 11.74 MWac at water elevation of +194 m. Due to seasonal variability, the power production decreases to 5.74 MWac at the lowest water elevation. Solar energy, on the other hand, has a great potential in Indonesia, this study is aimed to optimize the decrease in existing electricity production in Matenggeng Dam by hybridization of hydropower with floating solar power plants. According to the regulation of Indonesia’s public affair only 20% of the water surface area at normal condition can be used. By taking into account the reservoir operation pattern and the reservoir various conditions, the optimum water surface area that can be used for FPV installation is 295.7 hectare. The result showed that, the solar power plant successfully produces 14 GWh of energy annually, where the monthly generation is stable at 1,200 MWh per month.

An effective supply chain management has a significant role in preventing this type of delay. The aim of this research is develop risk simulation model of construction supply chain in buildings. The materials include steel bars, steel profiles, formwork, and precast concrete, as they are considered the main building material. The supply chain risks are classified from supply, control, process, and demand sides. Monte Carlo simulation has been performed using Cristal Ball software. Risk identification was done through literature review, site observation, and interviews with 29 contractor personnel  working for nine building projects. The simulation results show that the minimum, maximum, and most frequent delays (in days), as follows: steel bars (2.20. 17.05, 11.24); steel profiles (2.12, 15.10, 9.75), formwork (1.79, 16.04, 10.45), precast concrete (1.76, 15.61, 10.24).  The sensitivity analysis shows that delay due to change order from client is the most sensitive for  steel bars, steel profiles, and formwork of 25.5%, 37.4%, dan 17%, respectively. The results of this research is useful for contractors and owners who can use them as a guidance in identifying, predicting, and mitigating supply chain risks for a successful project.

Several studies related to the effectiveness of providing pedestrian bridges in Indonesia have shown a low level of utilization of pedestrian bridges. This study aims to determine the efficacy of providing an environmentally friendly pedestrian bridge prototype that was built by considering user needs from planning, design, and aesthetic criteria. Data were obtained through field surveys to get information on traffic conditions and bridge users and interviews to obtain information about crossing purposes and perceptions of needs. Statistical analysis of the average difference test was carried out to prevent bias in traffic conditions. Furthermore, descriptive statistical analysis was carried out to determine the effectiveness of providing pedestrian bridges obtained from comparing data processing results with the evaluation table. The results showed that the environmentally friendly Pedestrian Bridge prototype did not guarantee an increase in the number of users. Coercion through law enforcement and the installation of dividing lanes on the lanes can be seen as a solution. However, aesthetic and sustainable design is a necessity.

Styrene Butadiene Styrene (SBS) is a polymer that has proven its performance in heavy traffic, but it must be imported and expensive. Crumb rubber have high potential to be used as an asphalt modifier. Asphalt modified crumb rubber has high viscosity and is not homogeneous, so that the utilization cannot be delayed. This reduces workability in the field. This study aims to obtain asphalt modified crumb rubber which is easier to use by adding materials that do not affect its performance. RejIRE is a low viscosity additive to restore the properties of bitumen on crumb rubber modified. Experiments were carried out by adding variations in RejIRE levels to crumb rubber modified asphalt to determine its characteristics. Continued investigation of the performance of hot paved mixtures for wearing courses compared to asphalt mixtures with Pen 60/70 asphalt and SBS modified asphalt mixtures. The result is the addition of 0.75% RejIRE on asphalt crumb rubber modification have high workability. Overall the performance of the mix with SBS modified asphalt is better, but the mixture of hot paved with modified asphalt crumb rubber has a resistance to permanent deformation superior to the other paved mixtures.

Two approaches in predicting the magnitude and duration of impact loading, namely half-space approach and interaction approach, were studied in this paper. This study showed that load and structure response from both approaches were very different. Since the interaction approach considered the effect of structure flexibility on the load and response history, this approach showed more realistic results than the half-space approach.Keyword: impact, dynamic, plate, time historyPermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3667[How to cite: Nurhuda, I.

Environmentally friendly materials that can completely replace cement are geopolymer materials. This study compared the mechanical properties of PPC mortar and geopolymer mortar with and without white soil under seawater bath conditions. The test object is a 5x5x5 cm mortar cube with fly ash, white soil, sand, water, alkaline activator NaOH 8M, and PPC cement. Mortar variations include PPC mortar, geopolymer mortar without white soil substitution (TTP), and 15% white soil substitution mortar (TP15%). Tests include compressive strength, tensile strength, porosity, density, and absorption for all three variations. Microstructure testing of the influence of the bath is carried out on the TP15% mortar. The test results showed that PPC mortar has better resistance compared to both variations of geopolymer mortar in terms of its compressive and tensile strength at a bath life of 28 days, namely 32,427 MPa and 2,318 MPa, while the geopolymer mortar produced maximum compressive and tensile strength values of 14,373 MPa and 0.993 MPa. TTP mortar has better resistance than TP15% mortar. Microstructure testing showed mortar with baths had a denser matrix.

This paper presents results of the study on Wonogiri Reservoir operation during flood period after dike construction. The study followed a two-step calculation. It updated the design flood by employing rainfall data frequency analysis and Collins unit hydrograph. Flood routing was subsequently done by applying level pool method. Two conditions were considered, namely existing condition whose initial water level was +135.3 meters and new condition whose initial water level was +136.3 meters. The study reveals an increase of the flood discharge to Wonogiri reservoir by 7.7% and 3.6% for the 60 year and 500 year floods, respectively, as compared to the previous study of Pradipta (2014). The study shows that Wonogiri reservoir is prone to overtopping under 500 year flood. It is recommended to lower the control water level of the new spillway.

Consequently, the development of national and provincial roads should be based on tight implementation of quality standard for achieving stable road pavement. However, in current practices, there are evidences indicating no correlation between increased investment on national and provincial roads with the improved road quality in various regions though the road development uses an identical standard of quality manual. It is, therefore, very important to study performance of the quality manual standard implementation on road maintenance and betterment. The objectives of the research are to identify underlying problems and inappropriate practices of implementation procedure of pavement quality standard and to understand root causes of road deterioration occurred before the expected period of its life service. The research used a questionnaire survey completed objectively by respondents as with their expertise and experiences on road engineering. The respondents consist of 251 practitioners and experts selected through purposive method from 28 provinces representing the government staff of Public Work Department, supervision and consulting engineers, contractors and academic staff of universities. Furthermore, the questionnaires were compiled and analyzed by using descriptive statistical method. Findings of the research show that the underlying problems of the implementation of quality manual standards are predominated by low quality of human resources, inadequate utilization of testing instrument, and insufficient understanding of quality standards as well as poor coordination between implementation and supervision institutions. The substandard quality of road pavement mainly occurred due to low quality of the materials, inappropriate method of quality testing, improper construction method and insufficient field supervision. It was found that pavement deterioration in the beginning of road operation period is not caused by overloaded traffic but mainly due to inappropriate implementation of quality standards. This is regarded as no proper socialization of quality standards by government institutions for engineers, contractors and supervisors and their understanding on the road development is only focused on contract documents. Keywords: quality standard, implementation, road pavement, road maintenance, road betterment ABSTRAK Penanganan jalan nasional dan propinsi tidak terlepas dari penerapan standar mutu untuk mencapai kualitas perkerasan jalan yang mantap. Jalan nasional dan propinsi memiliki peranan yang amat penting terhadap peningkatan ekonomi wilayah karena berfungsi menyediakan mobilitas dan aksesibilitas antar simpul wilayah yang lebih luas daripada jalan kabupaten. Pada saat ini,  fakta mengindikasikan tidak adanya korelasi antara peningkatan investasi penanganan jalan nasional dan propinsi dengan peningkatan kemantapan perkerasan jalan meskipun standar mutu perkerasan yang digunakan sama, sehingga perlu dilakukan penelitian kinerja pemberlakuan standar mutu perkerasan pada peningkatan dan pemeliharaan jalan. Tujuan penelitian adalah mendeskripsiskan kendala dan penyimpangan pemberlakuan standar mutu perkerasan jalan serta penyebab kerusakan jalan yang sering terjadi di bawah umur pelayanan. Instrumen penelitian berupa formulir survai (kuesioner) yang harus diisi secara obyektif dengan memepertimbangkan kepakaran dan pengalaman responden  di bidang teknik jalan. Responden terdiri dari para pakar (expert) yang ditentukan secara purposive yang tersebar di 28 propinsi pada instansi kantor P2JJ dan litbang, kantor dinas pekerjaan umum, konsultan supervisi, kontraktor dan perguruan tinggi. Selanjutnya data terkumpul dikompilasi dan dianalisis secara statistik deskriptif. Jumlah responden (pakar) yang mengisi formulir survai sebanyak 251 orang. Hasil penelitian menunjukkan bahwa kendala implementasi standar mutu didominasi oleh kekurangan kualitas SDM, keterbatasan utilisasi alat uji, kesulitan memahami substansi standar mutu, dan lemahnya koordinasi antara pelaksana pekerjaan dan pengawas mutu. Selain itu disimpulkan penyimpangan mutu perkerasan yang sering terjadi adalah: (i) mutu material kurang tepat; (ii) metode pengujian mutu kurang tepat; dan (iii) prosedur implementasi metode pelaksanaan dan pengawasan di lapangan tidak tepat. Penyebab kerusakan perkerasan jalan pada awal operasional, tidak semata-mata disebabkan oleh kendaraan overloading tetapi lebih didominasi tidak tercapainya pemberlakuan (implementasi) standar mutu yang tepat di lapangan. Permasalahan lainnya adalah kurangnya sosialisasi standar mutu yang dilakukan oleh instansi pembina terhadap pelaksana dan pengawas mutu di daerah dan pemahaman mereka terbatas pada dokumen kontrak.Kata kunci: standar mutu, pemberlakuan, perkerasan jalan, pemeliharaan jalan, peningkatan jalanPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3956[How to cite: Mulyono, A.T., 2006, Kinerja Pemberlakuan Standar Mutu Perkerasan pada Peningkatan dan Pemeliharaan Jalan Nasional – Propinsi, Jurnal Media Komunikasi Teknik Sipil, Volume 14, Nomor 3, pp. 309-328]

Three-dimensional finite element analyses under cyclic loading were conducted to assess the influence of cover plates on different RBS geometries, including radius cut (RBSCP-RC), straight cut (RBSCP-SC), tapered cut (RBSCP-TC), and drilled flange (RBSCP-DF). The objective of this study is to investigate the effects of geometric variation on seismic response, moment capacity, and ductility of hybrid RBS–cover plate (RBSCP) connections. The novelty of this research lies in the systematic development and evaluation of a hybrid RBS–cover plate connection that combines the energy dissipation capability of RBS with the strengthening function of cover plates. This configuration is intended to shift plastic hinge formation away from the column face, reduce the risk of premature weld failure, and improve connection strength and energy dissipation. The numerical results indicate that the incorporation of cover plates significantly enhances the seismic performance of RBS connections, with the radius-cut configuration demonstrating the most stable hysteretic behavior and the highest energy dissipation capacity. These findings emphasize the importance of geometric optimization in hybrid RBS–cover plate designs and provide valuable guidance for improving the seismic resilience of steel moment-resisting frames.

The embankment can be built on peat soil, but it needs reinforcement that can contribute to increasing the stability of the embankment. The nailed slab system, as reinforcement, is expected to reduce settlement and increase the stability of peat soil. The aim of this paper is to study the effect of pile length and distance on the reduction of settlement in both monolithic and non-monolithic piles. The embankment load test was conducted on 70 cm x 120 cm plates, which were reinforced pile with different lengths and distances in the peat soil layer. The analysis was conducted on the reduction settlement of monolithic and non-monolith pile. The results showed that the length and distance of the pile had an effect on the reduction settlement. Changes in pile length are more dominant reducing settlement compared to changes in pile distance. Pile connection with slab has a significant effect on different lengths of piles than different distances piles.

This road is a provincial road with hilly terrain, lots of sharp turns, and long ascents and descents, which are potential for traffic accidents. Police data records that in February 2022 there was an accident on this road with 13 deaths and 33 injuries. Therefore, this study aims to evaluate road geometric, both horizontal and vertical alignments on Imogiri - Dlingo road based on Guidelines for Road Geometric Design number 13/P/BM /2021. To do so, road geometric analysis is conducted by employing road safety inspection data, which is then modeled using AutoCAD Civil 3D software. Based on the survey on road geometric, it is known that the number and width of lanes and shoulders are in accordance with Guidelines. Meanwhile, the analysis results using computer program show that this road has 24 horizontal and 6 vertical alignments. Nevertheless, 87% of bend radius, 67% of curve length, 58% of bend angle, 43% of slope, 57% of critical length, and 67% of control design (K) are not fulfilled the requirements. Therefore, Imogiri - Dlingo road is dangerous road and is potentially causing fatal accidents.

The increase in number of vehicles and high mobility make intersections as the points with the highest risk of accidents. The Special Region of Yogyakarta (DIY), as a province with dynamic tourism and economic activities, has a significant accident rate, with Sleman Regency contributing approximately 34.8% of the total 4,730 accident cases in DIY in 2018. This condition emphasizes the need for a comprehensive traffic safety analysis in this region. This study aims to analyze the safety level of intersections on primary arterial roads in Sleman Regency using the Swedish Traffic Conflict Technique (TCT). The approach was conducted by ranking road sections using the Accident Equivalent Number (AEK) and observing traffic conflicts using the TCT method. The results of the study show that all intersections observed have a high-level of conflict with a Time to Accident (TA) value that is close to or exceeds the critical threshold. Speed has been proven to be the main determinant of increased risk and severity of conflict. Therefore, this study emphasizes the need to calibrate the Swedish TCT threshold based on vehicle type so that the analysis results remain contextual to Indonesian traffic conditions. Technical recommendations focus on speed limits and the implementation of traffic engineering interventions.

There are several methods to overcome the damage caused by expansive soil, such as by mixing the soil with additives. Some researchers have conducted research by mixing additives into expansive soil (cement, lime, fly ash etc), which work to increase soil strength and reduce swelling. Considering that the people in Buraen Village of Kabupaten Kupang use white soil as a substitute for cement, where the white soil has chemical constituents almost the same as those owned by cement, and contain CaO as it has lime, it is necessary to do research to determine the effect of white soil on physical and mechanical properties of expansive soil, so it can be used as an additive. This research was conducted at Soil Mechanics Laboratory, Civil Engineering Department, Engineering Faculty, Diponegoro University, Semarang.with soil sample from Godong, Central Java and white soil in Buraen Village of Kupang Regency, which purpose to find out the change of physical and mechanical properties of expansive soil that have been given some variation of mixture of white soil  to the dry weight of the soil, with optimum moisture content from standard Proctor test results. The results of this study indicate that white soil can be used as an additive and the use of OMC for mixing is the OMC of expansive soil.

The ability of the building to endure all of the load during operation should be considered in design process. The irregularities in the building cause to impair stiffness and performance of the structure, particularly during the earthquake. Therefore, it is necessary to evaluate the effects of vertical irregularities on building, especially high-rise buildings. This study employs an S-Shaped structure with five vertical irregularities. Numerical analysis was used by using STEDA 3D software. The dynamic load used is based on time history data from the previous earthquakes, including the El-Centro, Kobe, and Parkfield. The seismic behavior evaluated in this study consist of shear force, lateral deformation, structural stiffness, the relationship between base shear and top displacement, drift ratio, maximum acceleration response, capacity curve, and top orbit of the building. Based on the numerical analysis results, it can be concluded that each model has a different seismic performance even though it is given the same earthquake load and material properties. The vertical irregularity of the building greatly affects the behavior of the structure due to seismic analysis.

Based on drilling data, it is recognized that the groundwater level is high and that the slope under the bridge has soil with a low standard penetration tests value (N-SPT) of less than 10. Hence, the stability of the slope is called into doubt. In order to strengthen slope stability under the bridge, this research will investigate slope stability while taking seismic loads into account and offer options for efficient slope reinforcement. By using the PLAXIS 2D software, the finite element method was used to analyze slope stability. The outcomes of the modelling suggest that the slope may not be stable, since it does not fulfill the design slope criteria, which are 1.8 for static conditions and 1.5 for earthquake situations. Respectively, the safety factor value is 1.396 for static condition and 1.068 when given an earthquake load. The design reinforcement model's results highlight that the subdrain reinforcement in combination with bored piles and ground anchors can fulfill the criteria for the slope of the bridge plan.

This is exacerbated by speeding driving behaviour of some road users.This research aims to identify the factors that cause traffic accidents and drivers’ behaviour at the curve; to review curve geometric design; and to develop a relationship among speed, curve geometric condition and the accident at the curve. This study simply reviewed three hairpin curves that were prone to be blackspots in Batang. The dominant factors that cause accidents were human error and road condition. The driver’s speeding behaviour was indicated by the speed that was lessen when entering and increase when leaving the curve. There were speed variations among vehicles in research location that could increase the number of accident. The results of the geometric review showed that the radius of all curves evaluated did not meet the standard, i.e. less than the minimum radius. Another result of this study was relationships among speed, geometric condition and accident number, as shown by the following formula: Speed = 0.095 Radius + 42.889, No. of accident = - 0.785 Radius + 0.008 Speed - 284.301, and EAN = 0.028 Speed  - 1108.689.

One of the important properties of concrete is ductility. Low ductility of concrete is presented by stress-strain curve, which has fast decrease of compressive strength in post peak load area, so collapse happen in relatively immediate. Nylon fiber has lower modulus of elasticity than concrete. The using of fiber is expected able to produce concrete more ductile. The objective of this research is to explore the effect of one kind polymeric fiber, nylon, in normal concrete (fc’= 30 MPa). The result shows that there is no significance difference in compressive and flexural strength in concrete with varied nylon fiber content, but there is significance difference in compressive strength among varied age of concrete. There is significance difference in modulus of elasticity of concrete. The modulus of elasticity will increase in line with the decrease of nylon fiber content.  This research show that higher fibre content added to the concrete, the concrete will show higher strength in cyclic loading.Key words: nylon, fibre, normal concrete, compressive strength, flexural strength, modulus of elasticity.

If the driving force at the slope is bigger than the resisting force, it can inflict a landslide. Gabions are one of the slope reinforcements structures that can be used to prevent landslides. Gabion has woven wire and has tensile strength.  This study aims to examine the effect of modeling of tensile strength on gabion wire using Plaxis 3D, as well as the effectiveness of variations in height, variations in tensile strength, variations in gabion reinforcement patterns on slopes. The soil is modeled as homogeneous loamy sand with a geometry of 10m high and 1:1 slope. Modeling the tensile strength of gabions can increase the value of the safety factor by 9.5% compared to without modeling the tensile strength of gabions. The optimal gabion height that increasing the safety factor is 6m. The value of the tensile strength of gabion wire does not have a significant effect on the safety factor of the slope.

To reduce the impact of losses resulting from dam collapses, it is necessary to analyze flood inundation patterns in the context of disaster mitigation. The dam failure analysis was modeled using HEC-RAS software with failure conditions due to overtopping and due to piping. The input in this modeling is the PMF plan discharge which is generated using HEC-HMS modeling with the HSS SCS method. The data required for HEC-HMS modeling are raster maps, land use maps, soil type maps and Hersfield method PMP rainfall plans. From the analysis results, it was found that the PMF planned flood was 115.54 m3/sec. The area of the flood inundation due to the collapse of the Tempuran Dam, the bottom piping condition was 2.61 km2 and the depth of the flood varied between 0 m to 3 m, where the area most deeply affected by the inundation was Purwosari Village, Blora Kota District. From the mapping results, the areas affected by flood inundation due to the collapse of the Tempuran Dam are Tempuran Village, Sendangharjo Village, Ngadipurwo Village, Purwosari Village, Patalan Village and Tempurejo Village. Where the fastest flood travel time is 48 minutes to Tempuran Village and the longest flood travel time is 5.25 hours to Tempurejo Village.

Although this method is well known in its implementation, the long procurement period often results in the slow procurement of infrastructure projects. As an alternative to the procurement method is the Design Build method. This method is believed providing many advantages compared to traditional methods. However, in practice there are obstacles that can hinder the application of this method. The purpose of this study is to analyze the herarchy of the obstacles to applying the Design Build method and formulate efforts to overcome these obstacles. A two-round paired matrix questionnaire survey using the Delphi technique was distributed to obtain consensus from the stakeholders involved in the infrastructure project procurement process. Subsequently, an Interpretive Structural Model (ISM) analysis is carried out to obtainthe hierarchy and the relationship between the constraints that can hinder the implementation of the Design Build method. Fourteen constraints were identified, which form a six-level framework that needs to be addressed in implementation.

The design of a reservoir needs to consider several aspects of soil embankment such as variations in water content and changes in shear soil shear strength and also the influence of water level in reservoir. The purpose of this research is to analyze these three aspects in the design of a reservoir. This research was begun by taking soil samples for embankment and conducting soil tests to obtain soil characteristics at the initial condition. The further laboratory tests were conducted to determine the effect of changes in water content on the shear strength of the soil. The variation of soil embankment characteristic was then modeled by Plaxis 2D program to obtain the effect of changes in soil embankment characteristic and fluctuation of the water level in the reservoir. The results showed that the increase in water content significantly decrease the shear strength of the soil. The changes of soil shear strength affect the pattern of slope failure and safety factor. In addition, the pattern and direction of the slope failure were also influenced by the water level of the reservoir.

The result of the study show that the addition geotextile-reinforcement increase soils bearing capacity up to 3 times of the soils without reinforcement. This increasing equivalent with increasing of geotextile-reinforcement dimensions and reduce with increasing of the depth of geotextile-reinforcement layer. qu and su of peat soil at the research has a different value, range 30 – 42 kPa for qu and 8 – 11 kPa for su. This difference show that peat soil has the ability to return to the condition before it compressed in the short time. Keywords: Peat soil, geotextile, reinforcement, bearing capacity, square footing. ABSTRAK Pembangunan konstruksi di atas tanah gambut menimbulkan banyak masalah, untuk itu perlu dilakukan penelitian mengenai perbaikan tanah gambut agar diperoleh daya dukung yang cukup. Dalam penelitian ini diteliti pengaruh penggunaan geotekstil untuk perkuatan tanah gambut pada bangunan dengan pondasi dangkal dengan memvariasikan kedalaman dan lebar, serta bagaimana pengaruh sudut penyebaran tegangannya. Dari penelitian yang dilakukan diperoleh hasil bahwa penambahan lapisan geotekstil akan meningkatkan daya dukung hingga 3 kali lipat tanah tanpa perkuatan. Peningkatan daya dukung sebanding dengan penambahan dimensi perkuatan yang digunakan dan berbanding terbalik dengan penambahan kedalaman. Nilai qu berkisar antara 30 – 42 kPa sedangkan su memiliki nilai antara 8 – 11 kPa. Perbedaan nilai ini menunjukkan bahwa tanah gambut memiliki kemampuan untuk kembali mengembang (unloading) dalam waktu yang singkat. Kata kunci : tanah gambut, geotekstil, perkuatan, daya dukung, pondasi bujur sangkar.

With changes in the Construction Services Law, there are differences in the form of revisions, additions, and reductions. These differences and changes are analyzed with the aim of developing a better Construction Services Law in the future. The method used in this research is a literature study method and questionnaire survey method. Questionnaire questions were formed based on literature studies from previous research and Construction Services Law discussed in this study. Data obtained from respondents were entered into the IBM SPSS Statistics 23 program and then conducted a validity test, reliability test, correlation test, and regression analysis. The analysis shows that there are several Construction Services Law’s regulations which cannot be a good guide for construction service providers and users yet, due to: the provisions regarding building failures are not well explained, the general lack of provisions governing the selection of expert assessors, the lack of clarity governing labor standards construction work and unclear regulations regarding sanctions for parties involved in construction work.

This study aims to determine the effect of the screw spacing to the bending capacity and behaviour of the cold-formed steel built-up box section which made from lipped-channel (1.0 mm thick, 81 mm web height, 8.5 mm lip height, upper and lower wing width 38 mm and 40 mm). A total of 19 beams with a length of 1200 mm each are subjected to pure bending moments by applying two point loads spaced 600 mm in the midspan. The screw spacing variations in the moment span are 100 mm, 150 mm, 200 mm, 250 mm, 300 mm, 328 mm, and 350 mm. The test results show the average of bending capacity of the beam test is increasing with the reduction in screw spacing while the screw configuration also affects the beam capacity. Analysis of the bending capacity using the effective width method and the direct strength method based on AISI S100-16 gives very conservative results. The failure mode of the built-up box sections were observed in the form of local buckling, distortion, and lateral-torsional buckling.

An alternative method is approached by modelling the lag screw as a beam element, with the limitations of modelling the contact interaction between the lag screw and timber members. In this study, diameter variations were also modelled to investigate joint behavior. To validate the model accuracy, a modelling was also performed in which the connectors and timber members were all modelled as solid elements and performed theoretical calculations. Numerical analysis was carried out by modelling the connection specimens using the finite element method in the ABAQUS software. The results showed that the connection capacity between solid element and beam element modelling are quite similar. The accuracy of modelling the lag screw as a beam element is lower at larger diameters and requires a method to correct the results.

Calcite was found in significant quantities in the ESP. The soil consistency limits are commonly used to evaluate the workability and estimate the mechanical properties of stabilized soil. The pH test was used to determine the initial Consumption of Lime (ICL), which was 8%. Several test variations were performed to investigate the effect of ESP replacement on the consistency limits of soil-lime stabilization soil, substituting ESP for a portion or all of the lime content required for stabilization. Soil-lime stabilization decreases the liquid limit, plasticity index, and linear shrinkage of the soil. With lime stabilization, the plasticity index reduced by 60% - 55%. The more lime content was substituted with ESP The greater the plasticity index. However, when all lime content was replaced with ESP, the soil plasticity index reduced by 29% compared to untreated soil. The shrinkage limit of untreated soil was 10.43%; after stabilization with 8% eggshell powder, the shrinkage limit increased by 26% to 13.22%. The shrinkage ratio, volumetric shrinkage, and linear shrinkage, on the other hand, are not significantly reduced. Lime types (hydrated lime and quicklime) have nearly identical behavior in terms of changes in soil plasticity. The eggshell powder can be used for soil stabilization and can affect soil plasticity. However, the changes in plasticity are not as significant as those seen with lime stabilization.

It is necessary to assess the resistance of the building in seismic performance in order to reduce and prevent earthquake-related damage and building collapse. With this evaluation, it is possible to predict the probability of building damage in the event of an earthquake. This study evaluates the performance of mosque buildings using the fragility curve to determine the probability level of damage. As one of the nations with the largest number of mosques in the world, Indonesia faces the challenge of overcoming the possibility of earthquake damage to the mosque buildings. In addition, many mosque buildings were built based on mutual cooperation without using detailed technical calculations. Therefore, an evaluation of the mosque structure is essential. This study employs a STERA 3D numerical simulation utilizing earthquake time history data. In this study variation, five types of earthquake time history data are utilized. Additionally, the irregular shape of the building is one of the factors under investigation. By performing a pushover analysis, the output of the capacity curve for calculations using the HAZUS method is obtained, allowing for the generation of a seismic fragility curve. The evaluation results show that different variations of time history data produce different levels of probability of damage.

The asphalt within the RAP generally had become stiffer due to ageing, therefore it needs to be mixed with a rejuvenating agent. An alternative organic oil-based refining agent that can be used for rejuvenating rigid asphalt is Waste Cooking Oil (WCO). The purpose of this study is to analyze the characteristics of asphalt mixtures at Optimum Bitumen Content (OBC) and at best WCO content. The asphalt mixture manufacturing method used was Marshall Method. The variation of RAP materials was 25% and 50%, with added aggregate material to meet the ideal mid gradation. For each variation of RAP content, was produced mixtures with variation of of 2%, 4%, 6%, 8%, and 10% (by weight of total asphalt) where for each of those variation of RAP with variations of WCO rejuvinating materials, were made asphalt content variation of 5%; 5.5%; 6%; 6.5%; and 7%, then the OBC was determined. For the mixture with 50% RAP, the OBC was 6.3%, with best result on 8% WCO. On misture with 25% RAP the  OBC was 6.2%, with best result on 4% WCO. The Marshall characteristics met the specifications. The mixture of 50% RAP with 8% WCO has lower stiffness and deformation resistance, however the performance of this mixtre was good enough on fatigue test.

All site factors used by SNI 1726:2012 are adopted from ASCE/SEI 7-10.  In 2013 Stewart and Seyhan proposed new and different site factors compared to ASCE/SEI 7-10. These site factors are then used for developing ASCE/SEI 7-16 with minor improvement for site class SE (soft soil). ASCE/SEI 7-16 states that the site factors for site class SE with SS greater than 1g or S1 greater than 0.2g, shall be calculated using Site Specific Analysis (SSA). The SSA method used for calculating site factor is difficult for ASCE/SEI 7-16 to be implemented in Indonesia. This paper describes the result of SMS and SM1 study at five cities (Jakarta, Bandung, Semarang, Yogyakarta and Surabaya) for site class SC, SD and SE using site factors proposed by Stewart and Seyhan and site factor SNI 1726:2012. The SMS and SM1 at five cities calculated using site factors proposed by Stewart and Seyhan are ±15% differences compared to SMS and SM1 calculated usingSNI 1726:2012 site factors.

This condition was experienced by the construction of Pasundan University’s new campus building within a narrow and congested location. This research carried out a productivity evaluation on the steel beam installation based on Time Studies, MPDM, Work Sampling and 5-Minutes Rating. Productivity analysis uses the MPDM, Cycle Chart, Process and Crew Balance Chart. The evaluation of the overall productivity of steel beam installation operations shows a comparison of the percentage of work execution versus delay of 62% versus 38%. This result is quite good considering that the proportion of construction worker productivity is in the range of 40-70% compared to 62% on this project. Improvement of productivity can still be done by preventing delays due to equipment; efficiency of the number of workers; as well as optimizing the duration of each task by referring to the best cycle duration. Thus, the productivity can increase from 10.36 minutes/unit to 6.25 minutes/unit. It is hoped that these results will attract similar research with objects to produce productivity data on construction operations in Indonesia and encourage an improvement in the construction sector.

The use of polypropylene fibers could prevent structure explosion by forming canals due to melted fibers during fire, thus release its thermal stress. This study aims to determine the effect of polypropylene fibers on compressive strength of high-strength concrete after combustion at 400ºC for five hours. High-strength concrete was made by w/c-ratio 0.3 with cement amount 550 kg/m3 and added with silica fume 8% and superplasticizer 4% by cement weight. The variations of polypropylene fibers were 0%, 0.2% and 0.4% of concrete volume. The compression test was carried out on standard cylinders Ø15/30 cm of combustion and without combustion specimens at 7 and 28 days. The results showed that compressive strength of high-strength concretes without using polypropylene fibers decreased in post-combustion compared with specimens without combustion, i.e., 0.81% at 7 days and 23.42% at 28 days. Conversely, the use of polypropylene fibers can increase post-combustion compressive strength with a maximum value resulted in adding 0.2% which are 25.52% and 10.44% at 7 and 28 days respectively. It can be concluded that the use of polypropylene fibers is effective to prevent reduction of high-strength concrete compressive strength that are burned at high temperatures.

SCC concrete can flow freely with its weight and is capable of filling a mold well, ensuring perfect compaction without vibration. In 1988, in order to eliminate or reduce the need for vibration to achieve density and thereby reduce the labor required for concrete placement, SCC was developed in Japan. In this research, the production of SCC was investigated by replacing the fine aggregate in the SCC mixture by 3%, 7% and 11% of zeolite material and by adding 0.005% of agave sisalana fiber of cement weight. The 15/30 cm concrete cylinders were used in 16 samples for compressive strength.  It is shown that the values of flowability, filling capacity, and permeability decrease with increasing use of zeolite content based on the results of the research conducted. The results of the compressive strength test show that the variation of 7% zeolite + 0.005% sisalana fiber has the highest value of compressive strength at FAS 0.43, with an average of 38.46 MPa, and the highest value of compressive strength at FAS 0.45, with an average of 37.07 MPa.

Despite its widespread use, CTRB is susceptible to shrinkage cracking, which can lead to reflective cracking in the surface layer and reduce pavement service life. This study investigates the performance of CTRB and a modified mixture incorporating emulsified asphalt—designated as IRBCAE (In-place Recycling with Cement and Asphalt Emulsion)—to mitigate shrinkage-induced cracking. Both mixtures were prepared using recycled aggregates containing 5.34% residual asphalt, with a composition of 49% surface course and 51% base course aggregates. Resilient modulus testing was conducted to evaluate mechanical behavior, and pavement structural responses were analyzed using KENPAVE software. The results indicate that IRBCAE exhibits viscoelastic characteristics with superior fatigue cracking resistance, whereas CTRB demonstrates higher stiffness and greater resistance to permanent deformation. In practical application, CTRB requires a thicker asphalt overlay to prevent reflective cracking, while IRBCAE enables the use of a thinner asphalt layer. The differences in structural performance between the two mixtures provide a basis for selecting suitable stabilization methods for recycled base layers.

Observation discharge data obtained from Pos Duga Air Sungai Temef is less reliable because the measurement of water level data for the last few years has been carried out by direct observation without using a discharge measuring device. Obtain river discharge data, it can be done by simulating rainfall data into discharge data, one of them is NRECA Model. In NRECA Model, there are several parameters, namely index soil moisture capacity (nominal), Percent Sub Surface (PSUB), Ground Water Flow (GWF), and crop coefficient (kc). Determination of the parameters NRECA Model was obtained by trial and error based on the value limit so that the coefficient correlation (r) between observation discharge and simulation discharge was close to 1. The values used for the index soil moisture capacity (nominal), percent sub surface (PSUB), ground water flow (GWF), and crop coefficient (kc) are 0,20; 0,85; 0,50; and 0,60.

This load is then distributed to the subgrade layer through pile of gravel under the ballast. Most of the design about the gravel layer (ballast) doesn’t take into account the effect of flood overflow on the rail, which is very likely to occur during rainy season. The Flood flows above the rail will reduce the ballast stability and then eroded. Part or most of the gravel were flushed out, thus resulting the ballast to be weak and may collapse, which is vey dangerous to the train traffic. Its therefore requires to investigate stability of the ballast under flood flow above the rail condition and any measure or improvement required by Hydraulic Modeling. The research is conducted at Hydraulic Laboratory, Diponegoro University. The model prototype is refer a tract rail at Mangkang-Semarang KM.12, with scale of 1:5. Its shown that the ballast  without a safety structure will start to scour when water level h1 = 15 cm , meanwhile with the structures Type 1 and Type 1 + 1 its start scour h1 = 17 and 19 cm respectively. The safety structure is able to scouring decrease , ie at the variation of h1 = 19 cm , there are 68.50 cm without structure, and with structure Type 1 and Type 2 are  29 and  26 cm respectively. This research shown that it needs to installing safety structure (sill) to reduce the danger cause of flood flow over the rail, especially at the flood prone area. The Management of train traffic could adopt this result how to protect of ballast scour cause of flood.

Criteria related to strength such as component plastic rotation capacity, lateral displacement as well as criteria related to damage of elements in the structures were used to evaluate the seismic performance of the buildings. Assessment to the moment and curvature capacities of the cross sections of beams and columns were done using XTRACT. The global seismic performance of the structures depends on the seismic performance of components in the structures. In nonlinear model of the structures, the degrading strength of the components were modeled to take into account the gradual reduction of the contributed components to the resistance of the structures. PERFORM-3D is one of the software that can be used to generate nonlinear model of structures. Seismic performance level of structures can be obtained from the results of the nonlinear dynamic analysis using PERFORM-3D. The Seismic performance level can be utilized for: (1) detecting any weaker part in the structures, and (2) evaluating the improved design of the structures for enhancing the seismic performance of structures.

Karena masa jenis beton slag juga meningkat, maka perlu diadakan penelitian lanjut tentang kemungkinan penggunaan beton-slag ini sebagai komponen struktural. Peningkatan kuat tekan beton yang seiring dengan peningkatan massa jenisnya membuka peluang penggunaan bahan ini sebagai elemen struktur yang tertumpu pada tanah, seperti misalnya balok basement, balok tie-beam dan rigid pavement. Namun demikian perilaku beton-slag terhadap respons geser (shear) belum diketahui dengan pasti. Uji laboratorium ini meneliti perilaku geser balok beton-slag yang diberi tulangan tunggal sedemikian sehingga pola kehancuran balok dipengaruhi oleh kehancuran gesernya. Hasil pengujian dibandingkan terhadap balok identik dengan agregat Pudak Payung sebagai elemen kontrol. Pengamatan terhadap balok-balok ini menunjukkan bahwa penggunaan slag meningkatkan kapasitas geser beton sebesar 11%, serta tidak terjadi pergeseran pada pola kehancuran. Kata kunci: Slag, Agregat Kasar, Kuat Tekan, Kapasitas Geser. ABSTRACT The use of steel slag as a substitute to natural aggregates for concrete increases the compression strength and workability of fresh concrete mixes. Furthermore, by solidification in the cement matrix, the pollution of heavy metals into soil and groundwater can be reduced significantly. The utilization of slag-concrete to be used as structural components need to be conducted especially since mass density increases as a function of slag percentage. Possible aspects are among others, basement components, tie-beams and rigid pavement elements. All these structures rest directly on supporting under layers, reducing their negative high mass-density effect. While compression and tensile behavior have been explored, the shear capacity of slag-concrete has yet to be investigated. This experimental work covers the behavior of singly reinforced concrete beams failing under shear mode. The result is compared to the controlling element, identical to the concrete-slag beam. The controlling beam uses Pudak Payung aggregates. The experimental research shows that the slag-concrete’s shear capacity increases 11% to the Pudak Payung concrete. The mode of failure however, remains the same.Keywords: Slag, Coarse Aggregates, Compression and Shear StrengthPermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3696[How to cite: Han A.Y. dan Narayudha, M.

Repair efforts are needed if the existing land has a fairly low CBR (California Bearing Ratio) value. Stabilization materials for soil improvement can use waste in the form of marble ash, and as a comparison in this research improvements were also conducted using the biogrouting method. The aim of this research is to obtain the effect of marble ash stabilization and biogrouting on the CBR value. The research was carried out through CBR tests on a physical model of soil stabilized with 3-6% marble ash and soil improved using the bacteria bacillus subtilis and bacillus amyloliquefaciens. Tests are differentiated based on the thickness of the stabilized soil, which is 10–30 cm. The research results showed that marble ash-stabilized soil resulted in a better increase in CBR values compared to soil improved using the biogrouting method. CBR values that meet standards for road construction base soils are obtained on soil stabilized with 6% marble ash with a minimum stabilized soil layer thickness of 20 cm.

Flood is a type of unsteady non-uniform flow, that can be simulated using HEC-RAS. HEC-RAS software is often used for flood modeling with a one-dimensional flow method. Unsteady flow modeling results in HEC-RAS sometimes refer to error and warning due to unstable analysis program. The stability program among others influenced bend in the river flow, the steep slope of the river bottom, and changes in cross-section shape. Because the flood handling required maximum discharge and maximum flood water level, then a steady flow is often used as an alternative to simulate the flood flow. This study aimed to determine the advantages and disadvantages of modeling unsteady non-uniform and steady non-uniform flow. The research location in the Kanal Banjir Barat, in the Semarang City. Hydraulics modeling uses HEC-RAS 4.1 and for discharge the plan is obtained from the HEC-HMS 3.5. Results of the comparison modeling hydraulics the modeling of steady non-uniform flow has a tendency water level is higher and modeling of unsteady non-uniform flow takes longer to analyze. Results of the comparison the average flood water level maximun is less than 15%  (± 0,3 meters), that is 0.27 meters (13.16%) for Q50, 0.25 meters (11.56%) for Q100, dan 0.16 meters (4.73%) for Q200. So the modeling steady non-uniform flow can still be used as a companion version the modeling unsteady non-uniform flow.

One of the road maintenance contract, i.e. performanced based contract (PBC), allows the contractor to design, build, and maintain the road and use performance measures as payment requirement. While many researches state that the PBC implementation on road maintenance may lead to cost efficiency, in Indonesia the cost efficiency is still questionable. This research is trying to answer the question by comparing actual road maintenance cost of two roads with same characteristics, while one is PBC and the other is traditional contract. The result shows that in one case PBC is cheaper than traditional contract, while the other case shows the opposite.

Therefore, traffic surveys conducted for a full year to obtain the Average Annual Daily Traffic (AADT) value used in road planning and design are difficult to obtain. To overcome these obstacles, the government has set the number of survey days for two days and seven days depending on its designation. This study aims to determine the error in estimating the Average Daily Traffic (ADT) based on the number of survey days. Data were obtained through field surveys using an automatic vehicle counter with a tool error value of 10%. The errors calculated include MAE, MAPE, RMSE, and Bias. The results of the study show that the number of survey days affects the magnitude of the error and the range of ADT Bias in predicting the AADT value. The number of survey days for two days, three days, and seven days showed good predictions. The Bias Range as a correction factor for the estimated AADT value is influenced by traffic conditions during the year. The correction factor with 95% CI based on the recommended research results for Road Type 4/2T or 2/1 is in the interval (1.40;-1.59) for a 2-day survey, and (3.92;1.17) for a 7-day survey.

The Indonesian government has built centralized domestic waste water infrastructure in 13 cities until 2014. According to USAID (2006) and AusAID (2013), idle capacity and cost recovery in the centralized domestic waste water system is still a major problem. Therefore, it needs to be done assessment management criteria of centralized domestic waste water management. This research is done by three-stage, that is construction models of a relationship of interdependence between management criteria; assessment of model suitability that has been constructed using SEM method; and calculate the weight of each management criteria using ANP method. The management criteria used on this study consist of: performance management, technical, institutional, regulatory, financing, and public participation. The weight of each criteria using models that have been assessment for their suitability, are: performance management (75.37%), financing (8.83%), public participation (8.39%), technical (3.56%), regulatory (2.36%) and institutional (1:49%). The global weight of sub criteria with most critical weight and should be a priority concern are sustainability (48.20%), public acceptance (14.90% 0, reliability (9.30%), willingness to pay (5.20%), and cost recovery (4.62%).

This structural system is better known as a flat slab. The flat slab structure is supported by column heads and drop panels, or without drop panels, or without column heads. Several building codes such as IS 456: 2000, ACI 318-08, ACI 318-19, EC 2:2004, and NZS 3101 (Part 1):2006 provide guidance for designing flat slab systems under gravity loads only. However, many flat slab buildings are also built in areas with high earthquakes which can cause the collapse of buildings due to earthquake loads. In this paper the 10-level flat slab building structure design results are analyzed using nonlinear time history response analysis with the help of OpenSees Navigator software using several earthquake records, namely Kobe (Japan, 1995), Imperial Valley (California, 1979) and Tabas (Iran, 1978) which has been adjusted to the design spectra of the city of Yogyakarta. From the results of the analysis using OpenSees Navigator, it was found that the story drift that occurred was still within the limits required in the regulations, so that the building being reviewed was still within the limits of life safety design.

Adequacy of funding for management can be planned based on the principle of full cost recovery or O & M cost recovery. One source of funding for the management of water resources as regulated in article 77, UU.RI Number 7, 2004 are the beneficiaries of which are service fees for water resources management (BJP-SDA). In order to realize the management of water resources with the principle of demand-side management and increase service fees for water resources management, it is necessary to analysis the correlation between the cost of management services to beneficiaries in accordance with existing regulations, commitment, and the contribution fee to be determined need to obtain agreement from interested parties (stakeholders) with the criteria that must be met. Important factors for the realization of cost recovery for water resources management in a basin area are: recovery policy management costs that will be done whether on the principle of full cost recovery or the O& M cost recovery, user groups according to water rights and the economic benefits derived each group of beneficiaries of development and management of water resources. Cost recovery model should be built at least with respect to these important factors. Keywords : cost recovery, users   Abstrak   Untuk menjamin kelestarian manfaat sumber daya air serta sarana dan prasarana keairan maka dana untuk pengelolaannya perlu disediakan secara memadai. Kecukupan dana  untuk pengelolaan dapat direncanakan berdasarkan prinsip full cost recovery maupun O&M cost recovery. Salah satu sumber dana untuk pengelolaan sumber daya air sebagaimana diatur dalam pasal 77, UU Nomor 7 tahun 2004  adalah dari para penerima manfaat yang merupakan biaya jasa pengelolaan sumber daya air (BJP-SDA).

Where buildings are built based on practical experience without structural calculations. One form of damage to non-structural components and structures is the relationship between columns and brick walls, where cracks and separation between columns and walls occur due to lack of anchors (cuttings). To find out how much an earthquake load can make a test object that uses anchor has been destroyed, a pushover analysis is carried out numerically and experimentally. From the numerical results it is obtained a pushover of 7490 kg and a displacement of 16.7 mm, while the experimental results obtained a pushover 7,540 kg and 56.5 mm displacement. Numerical results and experiments are very close at 99.34%.

Hydrograph data are the output of the catchment. It means that all the catchment behaviors are represented in the runoff data. The effect of temporal and the spatial variability of rainfall and the initial soil moisture condition has been represented in the runoff data. Hence, it’s necessary research about of design flood used on hydrograph. The research uses 16 flood events collected from Bojongloa sub-river basin and 10 data from Leuwigoong sub-river, which all included Cimanuk river basin in West Java. The filter separation autoregressive method is selected to separate the hydrograph to become baseflow and direct runoff components. The resulted direct runoff is then used for deriving the effective rainfall using inversely estimated rainfall (IER) method. The result of IER rainfall and IER pattern is used in design flood analysis using unit hydrograph IER method. And the observed rainfall are used as comparisons. The result show that design flood with hydrograph IER method is relatively similar with the observed rainfall. The result design flood with hydrograph IER method give accuracy between design flood the result of frequency analysis.Keywords : hydrograph, inversely estimated rainfalls, unit hydrographPermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3668[How to cite: Widyasari, T.

Understanding the implementation of construction work in atraditional area, especially those related to local wisdom, is one of the risk knowledge which is the first step inrisk conceptualization and is the aim of this research. A qualitative approach, which will elaborate on socialand cultural meanings to explain one of the phenomena that occurs in the world of construction in Papua, anddescriptive methods, are used in analyzing research data. The characteristics of the traditional territory wherethe project location is located also influence the construction risk value of a project. Based on the topographiccharacteristics of the region, there are four large groups of Papuan indigenous people, so there are differencesin the construction risk values faced according to the socio-cultural characteristics of each traditionalcommunity. Urban areas have a high construction risk and rural areas have a lower risk. The risk value ofconstruction projects in Papua is also influenced by the type of construction project which will be related tothe required land pattern.

Infrastructure projects have been the priorities in the past five years consistent with RPJMN (National Medium Term Development Plan). It’s evident in the percentage of contribution of the construction industry, i.e. 10.2%, to Gross Domestic Product (PDB) and 6.34 million employments (5.3% national labors). However, it isn’t followed by efficiency of the construction industry. Increased cost, implementation, delay, conflict and dispute are some problems which arise from fragmentation and causes the construction industry to be known as an inefficient industry. A possible approach to solve fragment problem is studying the supply chain of the construction industry. The present study aimed to measure supply chain performance of construction using SCOR (supply chain) method, the impact and mitigation. The result was that the handling performed in TSM Bali project resulted in 5.56% of indirect waste, 8.63% of direct waste, and 443,711 tonCO2 of carbon footprint

The success of the adoption of disaster insurance for public infrastructure is inevitably dependent on the acceptance of stakeholders. The aim of this study is to analyse the power and interest of stakeholders towards the use of disaster insurance for public infrastructure in Semarang. Data was collected via interviews and focussed group discussions with stakeholders of Semarang government officials, asset managers, users, etc. The power-interest grid of stakeholders divides the stakeholders based on their levels of power and interests, resulting in four categories, i.e. players, subjects, crowds, and context setters. This research identified the players are the Mayor, Regional Disaster Management Authority, and Regional Financial and Asset Management Authority (5.5%); the subjects category includes The Public Works Department of Human Settlements and Highways, Public Works Department, Trade Department, majority Public Health Center (40.7%); the crowds are Education Department and majority public schools (53.7%); and no context setters (0%). This study found that low trust in the insurer is a major factor causing a lack of interest in the use of insurance. The results of this study are valuable to understand the stakeholder map of Semarang city based on power and interest aspects, and serve as a basis for developing disaster insurance adoption strategies for public infrastructure.

This study aims to evaluate the effect of waste rubber tire replacement on bulk density, flexural strength, and sound absorption coefficient, while identifying the optimal percentage for the desired characteristics. The experiment varied the rubber tire content (5%, 10%, 15%, 20%, and 25%) as the independent variable, with specific gravity, flexural strength, and sound absorption as the dependent variables. The results show that increasing the percentage of waste rubber tires will decrease the concrete density, with a minimum concrete density of 1311.63 kg/m³ at 25% replacement. However, higher tire content will weaken the flexural strength, which peaks at 3.02 N/mm² at 5% replacement. On the other hand, the acoustic performance improves with more rubber content, reaching optimal sound absorption at 15% replacement, with a maximum coefficient of 0.22324 at 974 Hz.

Flood water level in the East Flood Way is affected by the discharge of storm water runoff and tide (rob). Facts on the ground indicate that the flood water level in the canal tends to increase from year to year. One possible reason is the increased flood discharge associated with climate change, besides the impacts of land use changes. This study aims to analyze the impacts of climate change on rainfall characteristics and their effects on flood hydrograph in the East Flood Way. The study begins with the collection and analysis of historical rainfall data to get a change of rainfall characteristics over time. The flood hydrograph was then analysed by HEC HMS. The results showed that in the period of last 30 years annual rainfall and maximum daily rainfall tended to increase of 22.64 mm / year and 2.56 mm / year consecutively, while the number of rainy days tend to decrease of 4 days / year. As a result of changes in the characteristics of the rainfall, the flood discharge of East Flood Way is expected to increase in the range between the 15.10 m3/s (31.5%) for 2-year return period up to 32.28 m3/s (25.5 %) for 200-year return period.

The wall structure used corrugated wall modules with bolted connections. The storage capacity of the observed silo is 4,650 tons of wheat grains with a diameter of 19 m and a height of 20.875 m. Numerical analysis was performed using the finite element method. The condition of the bolt connection is directly measured using a torque wrench. Measurement and analysis is carried out when the silo is full or empty. The measurement results show that the bolt tightening torque in the full capacity loading of grain is about 2 times than that of when empty. This indicates that the silo walls are subjected shear stress of bolts on the overlap area between wall modules. The asymmetrical inflating pattern of the silo wall during loading is caused by the variation of the bolt tightness torque at the connection between the wall modules. The calculation results show that the minimum bolt tightness torque to produce friction stress (in the overlap area between wall modules) which is equal to the grain pressure stress is 47.36 Nm.

Caused by this conditions, the radial roads are very crouwded especially in morning and afternoon peak hours. This crouwded traffic could be reduced by introducing the peripheral roads which connected some radial roads. Analysis method is making simulation model  by EMME/2  software. The as-built model is then calibrated by existing secondary and primary data for its significancy. After the model was built, it is conducted scenarios of the management of traffic flow on road network system by existing road network model. The optimum performance of road network system is benefit of this study. The study will give wider vision to macro movement efficiently without conducting costly field experiment. The improvement on road capacity and management implementation of traffic direction is possibly to conducted that simulation tool has accomodated the characteristics of movement and rute preference in natural way. There are 5 scenarios such as alternative 1 (one way direction), alternative 2 (road capacity improvement), alternative 3 (two way direction), alternative 4 (road capacity improvement and policy of one way direction) and alternative 5 (road capacity improvement and policy of two way direction). The study concluded that alternative 2 (road capacity improvement) and alternative 5 (policy of 2-way direction and road capacity improvement) will increase road performance. Keywords : road network, simulation, road performance, EMME/2. ABSTRAK Kota Semarang mempunyai sistem jaringan jalan dengan pola radial sehingga ruas-ruas jalan dengan arah menuju ke pusat kota menanggung beban lalulintas yang berat. Akibatnya, sering timbul kesemrawutan pada puncak pagi maupun sore hari, dan perlu dipikirkan pengembangan ruas jalan periferal yang menghubungkan ruas-ruas jalan radial. Metode analisis dilakukan dengan pembuatan model simulasi dibantu perangkat lunak EMME/2. Model yang terbangun dikalibrasi dengan data sekunder dan primer untuk menjadikan model yang signifikan kemudian dilakukan skenario penanganan manajemen arus lalulintas pada sistem jaringan jalan pada model jaringan jalan yang ada. Kinerja sistem jaringan jalan yang optimum merupakan manfaat dari studi ini dan hal ini akan dapat memberikan gambaran yang lebih luas mengenai efisiensi pergerakan secara makro tanpa harus melakukan ujicoba di lapangan karena biayanya cukup mahal. Peningkatan kapasitas jalan dan penerapan manajemen arah arus lalulintas dimungkinkan dapat dilaksanakan mengingat alat simulasi yang digunakan sudah mengakomodasi karakteristik pergerakan dan perilaku pemilihan rute secara wajar. Dalam studi ini dibuat 5 skenario yaitu alternatif 1 (satu arah), alternatif 2 (peningkatan kapasitas jalan), alternatif 3 (dua arah), alternatif 4 (peningkatan kapasitas jalan dan pemberlakuan jalan satu arah) dan alternatif 5 (peningkatan kapasitas jalan dan pemberlakuan jalan dua arah). Hasil analisis menyimpulkan bahwa alternatif 2 dan alternatif 5 dapat meningkatkan kinerja jalan.Kata Kunci: jaringan jalan, simulasi, kinerja jalan, EMME/2Permalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/Metadata/4183[How to cite: Yulipriyono, E. dan Basuki, K.H., 2009, Manajemen Arus Lalulintas pada Sistem Jaringan Jalan Kota Semarang Menggunakan Perangkat Lunak EMME2, Jurnal Media Komunikasi Teknik Sipil, Tahun 17, Nomor 3, pp. 257-271]

For this reason, it is necessary to develop a reservoir maintenance model based on multicriteria analysis relating to the type of maintenance. The method used Structural Equation Model (SEM) with the WarpPLS approach. The criteria used Structural Stability, Economy / Finance, and Physical & Environmental. The findings obtained variable structural stability has a very significant effect on the maintenance of irrigation ponds (r <0.01 and β = 0.73). Economic / financial variables have not significant effect on reservoir maintenance where r = 0.3 and β = 0.03. Physical and environmental variables also did not directly influence the maintenance of ponds with r = 0.29 and β = 0.03. However, the physical & environmental variables significantly influenced structural stability with r <0.01 and β = 0.32. Physical and environmental variables also significantly influenced economic/financial where r <0.01, and β = 0.45. This finding supported various previous studies for structural stability variable but different for economic/financial variables that did not significantly affect by the determination of reservoir types.

Among these materials is Ground Granulated Blast Furnace Slag (GGBFS), often referred to as slag-cement. The material is a residue produced during the steel refining process. The cementitious nature of the product makes it most suitable for ordinary Portland cement (PC) substitution. However, the behavior of this slag-cement in terms of development time and strength has not been defined in great details. In the construction industry, time is of major importance, a prolonged hydration process could delay the overall process. This research work focused on the setting time and strength response of slag-cement in mortar. The ratio of mortar constituent of cement-to-sand was 1 : 3. The percentage of slag-cement substitute to PC was 0%, 25%, 50% and 75% to the cement weight. The compressive strength was tested at the age of 14 days and 28 days. The results of the analysis showed that at a 25% slag-cement substitution a very significant increase in strength was shown. The increase was more pronounced at the age of 28 days when compared to 14 days and recorded to be 31.90%. As for the 50% and 75% slag-cement substitution, no significant increase in strength improvement was noticed. The test results showed a 2.66% enhancement for the 50% slag- cement substitution and a 2.45% increase for a 75% slag-cement replacement. The study also showed that slag-cement required a higher water-cement factor for the normal consistency

This study aims to analyze traffic performance at level crossings using a microsimulation approach with the PTV VISSIM software. The model is designed to explicitly simulate the interaction between trains and vehicles by utilizing features such as priority rules, public transport lines, and reduced speed areas, and calibrating it based on field data. This research takes a case study of the level crossing at Jalan Abdul Rahman Saleh – Nurtanio, Bandung City. Data collection was conducted through direct observation via field surveys and data from supporting literature documents. The analysis results indicate that the existing traffic performance is at a Level of Service F, with an average intersection delay exceeding 60 seconds per vehicle.

Numerical method is the most common method used in solving DE. Numerical methods that popular today are finite difference method (FDM), finite element method (FEM) dan discontinuous Galerkin method (DGM), which the method includes mesh based. Lately, the developing methods, that are not based on a mesh, which the nodes directly spread in domain, called meshfree or meshless. Element free Galerkin method (EFG), Petrov-Galerkin meshless (MLPG), reproducing kernel particle method (RKPM) and radial basis function (RBF) fall into the category meshless or meshfree. Time integration generally use an explicit Runge Kutta 4th order, Newmark- , HHT- , Wilson-  dll. This research was carried out numerical simulations DE, by combining the EFG method to solve the domain space and time integration with DGM methods. EFG using the complete order polynomial 1, and DGM used polynomial order 1. The equation used advection equation in one dimension. EFG-DGM comparison with analytical results also performed. The simulation results show the method EFG-DGM match the one-dimensional advection equations well.

In this study, the replacement of Portland cement using ground granulated ferronickel slag (GFNS) activated by the combination of sodium hydroxide (NaOH) dan sodium silicate (Na2SiO3) was utilized for producing alkali-activated mortar (AAM) as construction material. Four different mortar mixtures were prepared in this experimental work. There were three mixtures of ferronickel slag-based alkali activated mortar (FAM) with the variations of NaOH molarity of 6, 8, and 10M and cement-based mortar mixture (PCM) with water-to-cement ratio (w/c) of 0.5 was used as the control specimens. Overall, the flow and workability of the FAM specimen was lower than the PCM specimen due to the presence of silicate caused a sticky characteristic on the paste. On the other hand, the unit weight of FAM mortar was higher than the PCM specimen. Among all FAM mixtures, the most effective compressive strength and splitting tensile strength results were achieved by the FAM8 mixture, with a compressive strength at 28 days of 33.72 MPa and the splitting tensile strength at 28 days of 2.65 MPa, which had both good workability and chemical reaction of the material.

A quantitative descriptive–explanatory approach was employed using a questionnaire based on the ten core subjects outlined in ISO 21500:2021 Clause 7, which was distributed to 20 project personnel through a saturated sampling method, with data analyzed using descriptive statistics, validity and reliability tests, assumption testing, and multiple linear regression. The results indicate that the overall implementation level falls into the “Fairly Good” category, with an average score of 19.795, and the instrument demonstrates strong reliability, as evidenced by a Cronbach’s Alpha value of 0.938. Furthermore, regression analysis shows that information and documentation management has the most significant positive influence on system implementation, while procurement and lessons learned contribute negatively due to challenges in process optimization and organizational knowledge retention, with an adjusted R² value of 69.7% indicating a moderately strong model fit in explaining the variation in implementation levels. These findings highlight the need for improved procurement systems, stronger institutional learning mechanisms, and enhanced integration of ISO 21500:2021 practices to strengthen project delivery performance within the oil and gas construction sector.

One of the ways to improve workers’ productivity is using training and worker certification. Therefore, there is a need to analyze the effects of training and certification on worker productivity with case study lightweight brick and steel rods workers in some projects in Palembang. This study aims to analyze the productivity value of workers between certified trained workers (TS) and untrained noncertified workers (BTBS) in the field. Furthermore, comparisons were also conducted on productivity based on field survey and Indonesian National Standard (SNI). This paper also analyzed the significant factors that affect workers productivity in the field. This productivity appraisal used field observation methods and questionnaire. From the results of the study, it was concluded that the training and certification of the workforce greatly affected the worker’s productivity; but some of workers’ productivity of trained workers (TS) and untrained noncertified (BTBS) met the standards of SNI, some did not. This was due to the influence of other factors beyond training and certification of the productivity value of handyman. Furthermore, based on t test results, the factors that significantly affect the productivity of workers were the skills of labor (X1), work motivation (X2) and management (X4). Thus the available regression equation was Y =0,024 +0,332 X1 + 0,676X2 -  0,039X4 + e.

Although this segment geometrically can be considered quite good because it provides adequate stopping distance, the accident data from PT. Trans Marga Jateng showed that this segment is prone to accidents. This studyevaluated this segment's slope and slope length and their relationship to the potential for accidents. This segment was divided into three sections based on the slope and two vehicle types: light vehicles (LV) and heavy vehicles (HV). The results showed that the speed of LV was not significantly affected by slope and slope length variations, but this was not the case for HV. This condition results in a significant speed gap with great potential for accidents, especially at 00.00 – 06.00 and 12.00 – 18.00 when the driver is drowsy or fatigued. Therefore, an in-depth evaluation is recommended on the regulations allowing HVs to operate on toll roads, taking into account the weight-to-power ratio (PWR) and the maximum weight of the HV.

In order to appeal people to use this bus, the local government provides subsidy and applies the free fare, until today. It is expected that, when the subsidy is revoked in a few years ahead, people will get accustomed to use this bus. This research was conducted to observe public perceptions on the desired fare through ability to pay (ATP) and willingness to pay (WTP) analysis. Primary data was collected by doing survey over distributing questionnaires to the citizen. The bus corridors observed were on corridors I, III, and IV. The results showed that, the ATP-WTP of students were above the operator’s proposed tariff for all corridors. However, to attract those students to use the bus, it is recommended that the operator's proposed tariff (IDR 2,000 for each corridor) should be applied. For the general public category (PNS/TNI/Polri, Private Employees, Housewives, and other communities), the proposed tariff for each corridors were in between the average value of ATP-WTP. In that sense, tariff determination can be applied based on the average WTP value. However, the operator's proposed tariff for the public is still also feasible, subject to improving the level of services.

Therefore, the industry must be able to pay attention to human resources which are a valuable asset. One of them is related to the mental health of construction workers. Even though the construction industry is known for its stressful environment, not much research has been conducted regarding the fulfillment of mental health aspects of construction workers, especially in Indonesia. In fact, various mental health disorders such as depression and anxiety can have an impact on the performance of construction workers and industry. This research aims to identify various factors related to mental health that influence construction workers through an integrative literature study. The results of the analysis succeeded in finding 68 factors related to mental health in the construction industry which were grouped into four domains, namely types, causes, impacts and solutions to overcome mental health disorders in the construction industry. Identification of these factors and domains is important as a means of understanding mental health aspects so that they can become a reference for stakeholders, especially the government and construction project organizations, in an effort to increase awareness on the importance of mental health in the construction work environment. In this way, the government and construction project organizations can be proactively involved in realizing the achievement of sustainable development goals, namely good health and well-being.

One of several methods to accelerated a schedule is applying overtime work. Overtime work achieves schedule acceleration by increasing the amount of hours worked by labor beyond the typical 8 hours worked per day and 40 hours worked per week. Although there may be positive short-term benefits to working an overtime schedule, the long-term consequences are typically viewed as detrimental, such as fatigue, reduced productivity and safety, and increased absenteeism. The objective of this research is to present the effects of schedule overtime on construction labor productivity, and the impact of loss labor productivity to the labor costs. Overtime in this research is defined as the hours worked beyond the normal straight time hour (08.00 – 16.00). The data were collected by field observation and interview with the foremen. Field observation held in four weeks, with 28 labors included. The result of this research show a decrease labor productivity by 8,87% - 11,84%, and increase labor costs by 58,63% - 79,31%.

Digital Image Correlation (DIC) is non-contact technique in which digital images of the surface of a test object are captured using high-resolution cameras.  This study conducted measurements of strain distribution on the specimen's surface using the DIC method throughout the entire tensile testing process. The study particularly focuses on examining changes in strain distribution during the melting phase and the local deformation phase leading to fracture. In this research, a comparison will be made between the load-displacement curves obtained from experimental laboratory testing and the results analyzed using the DIC method for SS400-grade steel material. Based on the results of the tensile test and DIC analysis that have been conducted, conclusions have been drawn in the research. The tensile test results of SS400 steel material with a thickness of 6 mm, 8 mm, 10 mm, and 12 mm meet the quality requirements in the tested specification standards, and the results of the force-displacement curve between the experimental test results and the DIC method obtained a minimum deviation with a value below 10%,. Therefore, it can be concluded that the DIC method exhibits a reasonably good level of accuracy, making it suitable for validating the results of experimental tests.

Never the less most of the developments were limited on working process and lack in people empowerment. Toyota Way which integrate working process optimization and people empowerment, was developed as a lean construction frame works. This paper aimed to assess the implementation of Toyota Way principles in project delivery system by observing project’s delivery current state (status quo). The assessment began by conducting a questionnaire survey about Toyota Way implementation which then validated by interview with involved stakeholders and field observation. The assessment showed that project’s stakeholders were still unfamiliar with Toyota Way concept. Although some Toyota Way guidelines have been used in projects completion process such as visual management and training program, it found that those guidelines had not fully implemented. The project delivery system was lack of process focus and concerns more on relationship inter-parties. It also found thatToyota Way implementation will constrained by the difficulties to change the status quo of project delivery. Moreover, it seems that construction projects need practical guidelines to simplify the Toyota Way implementation in project delivery system such as project flow evaluation and system of reflection.

Jalan MT. Haryono is one of the roads in Kendari City which often experiences traffic jams, especially during rush hours, where on this road section there are two signalized intersections close to each other, namely the Pasar Baru intersection and the GMT intersection, which are separated by a distance of 500 m. The aim of this research is to determine the optimal cycle time in implementing a coordinated signal system at an intersection. With the implementation of coordinated cycle times, the degree of saturation decreases and intersection performance increases because queue lengths and delays are successfully reduced. On weekdays, queue lengths drop to 122 m in the east and 76 m in the west, with delays reducing to 108 seconds in the east and 80 seconds in the west. Meanwhile, on holidays, queue length drops to 94 m in the east and 88 m in the west, with delays reduced to 85 seconds in the east and 76 seconds in the west.

Runoff occurred when rainfall cannot be infiltrated and flowed on the ground surface. Cidanau watershed has quite high rainfall average (2573 mm/year) so it has high runoff potential. Zero Runoff System (ZROS) is one of water conservation way which can infiltrate runoff to the ground using permeation structures. ZROS’s successful parameter in order to decreasing runoff rate can be observed by the soil water content differences before and after ZROS application. Soil water content estimation was conducted by water balance model with and without runoff and then it is compared with soil water content from measuring. The simulation results indicated that soil water content in the research field before and after ZROS application is 0.476 and 0.569 m3/m3 respectively. The simulation is also conducted for past 10 years (2004-2013) and resulted higher soil water content if ZROS were applied. This results indicates that ZROS capable to decrease and permeate runoff to the ground and then increase soil water content level. Water balance model with and without runoff has coefficient of determination (R2) 0.606. It means that this model could simulate the soil water content differences before and after ZROS application valid relatively.

Generally in calculation, the upper structure is considered separate from the lower structure. If long term consolidation is included, the problem will occur when a relatively very rigid structure (on shallow foundation) is assumed to cause relatively uniform settlement, so as to assume no differential settlement. Whereas, uniform consolidation settlement is induced only by non-uniform soil reaction, so that this problem can never be solved with the assumption of separate upper-lower structures. In this paper, a method of structural calculation is suggested so that building may undergo uniform settlement as long as the soil consolidation occurs, without causing any damage to the building. The calculation is performed using special program with assumption that the induced soil reaction is always to cause uniform settlement. From this method, a procedure of soil –structure interaction is proposed that building on soft soil may experience large settlement without damage.

The land area affected by tidal floods is getting wider and wider, so there needs to be an analysis of the level of vulnerability of tidal flooding so that the handling and prevention efforts can be on target. Determination of zonation with the level of tidal flood hazard involves various criteria, for this reason the AHP and GIS integration method is used to make rational decisions from several criteria and draw them on a zoning map. The results obtained in the North Medan area showed that 30.91 ha (0.33%) had very high levels, 1,515.98 ha (16.09%) had high levels, 4,411.92 ha (46.83%) had moderate levels, 3,176.83 ha (33.72%) had low levels, 284.81 ha (3.02%) had very low levels of vulnerability to tidal flooding.

This allows it to serve as an alternative source of electricity for the building above it. The goal of this technology is to help achieve sustainable infrastructure targets by minimizing the use of fossil fuels from a geotechnical perspective. This study aims to analyze the thermal effect on foundation deformation using the Finite Element Method approach. The modelling is done using PLAXIS software with element meshes to provide comprehensive deformation results. Additionally, the model is used to vary the thermal parameters of the soil and the quality of the foundation concrete. The analysis results indicate that variations in thermal conductivity values lead to a 34.112% decrease in deformation due to reduced thermal conductivity, while variations in the quality of concrete used in the foundation show a relatively small or insignificant effect on the deformation.

Karimunjawa Islands which is located on Java Sea, 90 kilometers North of Jepara and which has been becoming a developing tourism site, needs concrete building for infrastructure. Karimunjawa sand is not eligible for building structure, so a qualified guarantied concrete is very expensive because must use Java sand which must be brought up by ship. It is necessary to use some local material in large quantities for getting an economic concrete price. This research attempts to substitute Muntilan sand by gradual increasing in composition to get a qualified –economic concrete, and will find its relation to the cost. The substitution values starts from 0% to 100%. The mix-composition is 1:1.5:2.5, wcf 0.5, cement from Gresik company, and coarse aggregate from Karimunjawa (local) and from Jepara. Water from Karimunjawa. The price of material and labour wage are prevailed when research is being done. The result are: there is a relation between improvement of sand gradation with both of quality and cost of concrete. The larger the composition of substitution, the higher quality and the more expensive its cost becames. In the quality from fc’ 8.4 MPa tp 14.1 MPa, concrete using local crushed stone was 8.43% cheaper than concrete using Jepara crushed stone.

Such destructions were due primarily to the fact that such structures were not designed to withstand a tsunami. Those which were designed to withstand tsunami force may also have been destroyed due to some damaging factors which were not included in the design. The damage of the coastal structures is one of the important factors that have caused casualties. Especially, when the destroyed structures were originally aimed to mitigate the area against tsunami, they may cause higher fatalities. Examples of such structures are sea walls in many parts of Japan which were destroyed by the 2011 tsunami. This paper discusses the important factors relevant to the damage of seawall as tsunami mitigation structure such as impact force due to tsunami front, hydrostatic force, and hydrodynamic force, debris force and scour due tsunami. The study was carried out based on literature about the damages of seawall as tsunami protection structures and laboratory experiment reports. The destructions to the structures were divided into three classifications namely instantaneous direct destruction due to impact and drag forces, slowly direct destruction due to drag force, and slowly indirect destruction due to scour. Finally, important aspects to be considered in the design of seawall as tsunamis protection were proposed.

The acceleration of assemblying – deassemblying – reassemblying and re-use of formwork become one of the alternatif selection for the type of formwork. Analysis of the formwork subject to service load (self weight and impact load) is compulsory to avoid unexpected failure. Selection of the best construction method and site conditioning according to the design, especially for pouring the concrete in a sloping area, is very crucial since it does not only influence time construction, but also type of material, equipment, and service load during the construction.

The dam rehabilitation requires a desk-study for the potential agriculture and raw water produced. The study methodology includes: monitoring the existing dam; monitoring results analysis consisting of hydrological, geographical analysis and river basin simulation; recommendations for the axis location of the dam with its optimal and effective storage capacity. The results of the geographical analysis and simulation, show that the location of the main dam axis needs to be shifted upstream at the axis position from 10029'41.86"LS and 121056'37.39"BT to 10029'47.29"LS and 121056'41.87"BT. The rainwater catchment area obtained from this analysis is 415,5 ha. With a simulation of a 9,0 m embankment height, it will provide a reservoir storage volume of 1,100 MCM. As a conclusion, it can be written that this dam analysis desk-study is faster and more cost-effective in finding the optimal reservoir capacity and effective dam height. This study needs to be continued by conducting a field survey and detailed analysis.

It is a signalized intersection which shaped roundabout. It lies on the truck track from west to east of Java Island, which is crossed over by Flyover Yos Sudarso – Siliwangi and Flyover Sudirman – Siliwangi. Formerly, the flyover is designed for Siliwangi – Yos Sudarso vice versa. The flyover could decrease truck volume from east to west, on the contrary heavy vehicle movement is still overburden Kalibanteng Intersection capacity. On 2018, it is planned that Ahmad Yani Airport access road will be diverted. Thus, it is important to increase Kalibanteng Intersection performance, and accommodate the airport access divertion plan at a time. This research is aimed to identify the existing movement pattern at Kalibanteng Intersection, to evaluate the existing signalized intersection performance, to develop a simulation of two way management on Kalibanteng Flyover, to analyze the movement pattern due to the implementation of two way management on the flyover, and to analyze the signalized intersection due to this management. The results show that the highest movements in Kalibanteng Intersection are the movement from Siliwangi to Yos Sudarso (which is dominated by heavy vehicle) and from Siliwangi to Sudirman (which isi dominated by light vehicle and motorcycle), and will keep on increasing in the future. These movement greatly contribute on intersection performance. This shows that the utilization of the flyover for two-way movement can be considered with mode type limitation. Using two-way flyover, the performance of Kalibanteng signalized intersection will increase.

It is known that such SUH methods are still empirical, thus making it difficult for users to determine a representative method. Meanwhile, the hydrodynamic approach such as the SWE numerical model can achieve more accurate results in predicting the direct runoff compared to the SUH methods, because the model itself is derived mathematically based on the physical processes. The findings indicate that the direct runoff predicted using the SWE numerical model (HEC-RAS 5.0.7) produced more accurate results for the peak discharge with an average error of -0.07%, the peak time with an average error of 19.77%, and the shape of the hydrograph with the smallest Root Mean Square Error (RMSE) from all the cases tested. Therefore, it can be concluded that in the future the use of a hydrodynamic approach is highly recommended for the direct runoff prediction. This paper was also aimed to be used as a reference in the development of new, more accurate SUH method in the future.

This layer is recognized as the ITZ (Interfacial Transition Zone) and considered the “weak link”, since micro cracks are commonly initiated in this area. The properties of this ITZ are jet to be investigated. SEM (Scanning Electron Microscope) images only provide qualitative information such as formation, type and relative amount of crystals. Therefore, other means are required to represent a better understanding to the behavior of the ITZ. The mechanical and physical properties of the ITZ are highly influenced by the differentiation in porosity and strength. A mathematical or FEM (Finite Element Model) can be used to bridge this lack of information. This paper deals with the the modeling approach of ITZ as well as the concept of laboratory testing for validation of the model.

DAM is the method that is featured by AISC. Based on DAM, Rafael Sabelli proposed another method called Indirect Analysis Method (IAM). IAM is a new method that has not generally been used, and also has not been included in the AISC Specification. This research is conducted in order to study IAM and compares the analysis results of IAM with those of DAM. Using a nonlinear structural analysis software, design and analysis were conducted for stability design of an eight-story building loaded with dead load, live load, and wind load. IAM provides a simple amplifier approach which is called B3 to address the member inelasticity, member imperfections, and uncertainty in member stiffness. From the study that has been conducted, the analysis results using IAM show close values with those of DAM, in terms of demand-to-capacity ratios, with IAM is more conservative than DAM. The use of IAM simplifies the design process without affecting the economy of the design.

However, each construction project has different risks, becaused the environmental conditions of the project, so that it requires handling different methods of project implementation. This study aims to: 1) analyze the risks that could potentially occur during the construction of the log dock extension; 2) Appropriate Handling Methods for the Implementation of the Log Dock Extension Work. The research method is done by identifying the risks that occur in the field and with the interview method about the possibility of possible risks that occur. The results of the study indicate five high-risk categories according to the perception of service providers that most influence on project delays. These risks include unpredictable external phenomena, such as tidal elevations that exceed plan, resulting in changes in design and method of implementation. The conclusions of this study include that the application of risk management to the implementation of the log dock extension project at the port of Tanjung Emas Semarang needs to be applied to minimize delays and reduce unexpected costs.

This paper discusses some causes of plastic deformation occurred in the field and some factors that effect occurring plastic deformation. Plastic deformation found in the field is effect of bad design gradation and of high bitumen content as caused mix design without void in mix at refusal density. Plastic deformation with rut depth is less than 20 mm, displacement or shear occurred on the wearing course (ACWC). In spite of rut depth is more than 20 mm, displacement or shear also occurred on the second layer or binder course (ACBC). Base on rut depth above, so we can used as a guide for determining of asphalt layer is should be scraped or repaired. Giving attention for example to consider void in mix at refusal density on mix design and the uses of asphalt mixtures which relatively high stiffness can reduce plastic deformation.Keywords: flexible pavement, plastic deformationPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3896[How to cite: Nono dan Yamin, R.A., 2005, Study Kasus Deformasi Plastis, Jurnal Media Komunikasi Teknik Sipil, Volume 13, Nomor 1, pp. 48-59]

This study began with field investigations at six points. Seismic response analysis was built using a one-dimensional wave propagation model with linear and non-linear equivalent methods. The 2007 Bengkulu-Mentawai earthquake wave was applied as the input wave. This study compares PGA, spectral response acceleration, and amplification factors produced by the two methods. The PGA value created by the linear equivalent method is approximately 5%-30 % greater than the non-linear method. The amplification factor produced by the linear equivalent method experiences a greater amplification of roughly 3%-30 % than the non-linear method. Spectral acceleration has generally exceeded the seismic design applicable in the short period, with a value of 1.2g - 2.1g for the linear equivalent method and 1.1g - 1.6g for the non-linear method. Therefore, updating the seismic design for building planning in the Selebar District, Bengkulu City, is necessary.

Therefore, company should pay attention to labor wages. Unfortunately, existing data about construction labor wages in Indonesian are only showed as daily wages (for labor) and monthly wages (for employee/permanent staff), while there’s no information about their labor burden. Therefore, objectives of this study are to identify the component and structure of construction labor burden and wages in Indonesia and also to identify all factors related. Research method used int this study are empirical and inductive methods. After all data has been collected from field survey, description of the construction labor burden and wages model was compiled into its components. Moreover, comparison analysis used to identify factors related to construction labor burden and wages. Results of data processing and analysis shows that: 1) Construction labor burden in Indonesia for both employee/permanent staff and labor commonly consist of direct and indirect payment, and conditional and lumpsum payment, but there are different distributions between each kind of labor. 2) Construction labor burden and wages in Indonesia commonly depend on company profile, project profile, and labor profile.

This study was conducted to determine the potential for liquefaction based on soil grain size distribution and CPT data in the UII Hospital area in Wijirejo Village, Bantul, DIY. Based on its geographical location, the Bantul district has a high earthquake potential because it is near an opak fault and is located in a subduction zone between the Indo-Australian Plate and the Eurasian plate. Along with this, there is urgency for this research. Analysis based on the grain size distribution of the soil was evaluated using the Tsuchida curve (1970). Analysis based on CPT data was evaluated using the Seed & Idris (1971) and IM Idriss & RW Boulanger (2008) equations to obtain a soil layer safety value, which was then used to predict the level of potential liquefaction with the LPI value using the Luna & Frost (1998) equation. Based on the grain size distribution using the Tsuchida curve (1970) in Wijirejo Village, the soil layer at a depth of 1 meter is dominated by sandy soil and silt, which has liquefaction potential. Based on CPT data, all sondir points have a very high liquefaction potential with consecutive LPI values 48,405; 52,160; 57,498; and 46,942 with a potential liquefaction zone depth of 0.20 to 13.20 meters from the ground level.

The liquefaction Severity Index (LSI) method can be applied to determine the liquefaction vulnerability level. This paper presents a study of liquefaction using LSI method to compose the liquefaction vulnerability map in a coastal area of Bengkulu City i.e., Lempuing Subdistrict. This study was conducted by analyzing CPT data in Lempuing Subdistrict to obtain the Factor of Safety and the probability of liquefaction. Peak Ground Acceleration (PGA) was assumed as 0.5g, which refers to SNI 03-1726-2012. Furthermore, the value of liquefaction probability and factor of safety obtained was analyzed to obtain LSI index and adjusted to the specific categories i.e., very low (0<LSI<15), low (15<LSI<35), moderate (35<LSI<65), high (65<LSI<85), and very high (85<LSI<100). Based on the analysis result, Lempuing Subdistrict was categorized as a very high to the very low susceptible area to liquefaction. The very high susceptible area was located on the eastern Lempuing Subdistrict bordering to the Gading Cempaka Subdistrict. The high susceptible area was located on the northern Lempuing Subdistrict bordering the Tanah Patah Subdistrict. Moderate to very low susceptible areas were located in the middle, west, and south of Lempuing Subdistrict.

POFA contains pozzolanic properties such as those contained in cement so it has the possible to be used as a mineral in concrete mixtures. Therefore, the use of POFA and seawater in concrete mixtures have the potential to be implemented, but it is obligatory to pay awareness to the potential for corrosion that also follows. This study aims to evaluate the use of POFA up to 20% as a replacement for cement and the effect of mixing seawater on the strength and corrosion of reinforcing bar in concrete. The compressive strength of concrete was evaluated by carrying out a compressive test on a cylindrical specimen with 100 mm in diameter and 200 mm in height at 7 days and 28 days of age. Furthermore, a concrete cylinder specimen with a diameter of 10 mm reinforcement was used to evaluate the potential for corrosion. Measurement of corrosion estimation using the half-cell potential (HCP) method based on ASTM C876-15. Test results show the use of up to 10% POFA to replace cement by mixing seawater and treated with fresh water has a high strength that is almost the same as normal concrete. The risk of corrosion is also not detected and proven by actual measurements of corrosion. Furthermore, HCP values more negative than -400 mV are predicted to experience corrosion in the reinforcement area above 10%.

This study aimed to determine the application of continuous improvement in construction projects according to kaizen philosophy. The research was conducted using descriptive analysis to describe the process of continuous improvement in a construction project. Data were collected using a questionnaire method on 24 building and road projects and interviews with two contractors. This study's results indicate that the application of the kaizen principle in construction projects is still limited. The research reveals that project planning has been carried out but not entirely following field conditions, standardization of work methods already exists but not detailed, all parties in the project have been involved in the construction process, but initiatives to make improvements have not been seen because it is still focused on corrective evaluation and work completion. The challenges in implementing continuous improvement are the lack of a quality management system, lack of working time, lack of consistency in the implementation of quality, and lack of worker’s skill in carrying out work. Some improvements required to support continuous improvement are to encourage top management's role in the application of quality management systems and internalization of the kaizen principle to all workers. The involvement of all production elements in maintaining product's quality in the internal system also needs to be improved.

Fatigue analysis is usually carried out to predict the service life of structure due to fatigue on its joints. Fatigue damage is also depent on Stress Concentration Factor (SCF). SCF is the ratio of hotspot stress at joint to nominal stress on member. Hotspot stress is extreme stress occur at intersection of the joint. In this paper, the calculation of SCF at joint T is carried out by using Finite Element Method that available in ProEngineer Software.  The resulted SCF based on Finite Element Method will be compared to calculated SCF based on empirical formula. In addition, SCF on joint T will also be compared to SCF on joint with tubular stiffener.Keywords: fatigue, failure mode, offshore structures, stress concentration factorPermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3910[How to cite: Tawekal, R.L., 2005, Perhitungan SCF Untuk Analisa Fatigue pada Sambungan Struktur Anjungan Lepas Pantai, Jurnal Media Komunikasi Teknik Sipil, Volume 13, Nomor 2, pp. 63-74]

However, The HSS method generally has shortcomings, including difficulties in explaining the origin of peak discharge formulas and inaccuracies in comparing hydrograph volumes with effective rainfall. Additionally, there are challenges in adapting the method for different rainfall durations, and only a few methods can be calibrated. To overcome these challenges, the ITB SUH method has been developed with several innovative features. This method follows the mass conservation principle and simplifies the process of deriving peak discharge formulas, making it an effective educational tool. The ITB method combines exact and numerical approaches in calculating the Peak Discharge Factor (Kp), improving the accuracy of peak discharge estimation, which is very important in flood management. This method also introduces the Normalized Unit Rainfall Duration (Tn), a dimensionless factor that provides flexibility in adjusting the hydrograph duration, making it easier to convert to shorter durations. In addition, the ITB method includes a calibration mechanism that allows users to adjust the hydrograph with measurement values. The ITB SUH method's innovative features have been successfully demonstrated in various cases, yielding highly positive outcomes.

Both types of contracts have their own risks. Therefore, it is necessary to measure which type of contracts is more risky between traditional contract and performance-based contract from the perspective of the contractor using Analytical Hierarchy Process. Analytical Hierarchy Process (AHP) is a method used to find a weight where the intensity of the risks using traditional contract and performance-based contract can be measured and analyzed. This research took sample for project with a traditional contract is Kendal – Semarang Road Project. While the samples for the project with a performance based contract is Semarang – Bawen Road Project. The results of the calculation by the alternative assessment, are the higher rank is performance based contract which is 0.56 (56%), while traditional contract is the second with the total score 0.44 (44%). The mean is performance based contract more risky than traditional contract from the perspective of the contractor.

However, the use of slender beams in a structure is susceptible to overturning and torsion occurrence. Therefore, lateral bracing is usually placed in several points of the beam to prevent lateral-torsional buckling. In this study, a three-point bending test was conducted to evaluate the capacity of 250 mm x 50 mm x 2500 mm Laminated Veneer Lumber (LVL) beams made from Sengon. Two lateral supports were placed at both ends to prevent the beam's lateral displacement. The bending test result shows that the ultimate load of the LVL beam reach 27.88 kN before failure. Furthermore, the LVL beams' bending capacity was calculated using the mechanical properties provided by several previous studies. The LVL beam's capacity was predicted using manual calculation (based on SNI 7973: 2013) and numerical analysis. Numerical analysis was performed using ABAQUS software, and the results were evaluated using the Tsai-Hill and maximum strain failure criterion. The results showed that the maximum strain criterion provides a better prediction of the LVL beam's capacity than Tsai-Hill failure criterion.

The groundwater contribution to fulfil raw water requirements in metropolitan bandung is realatively decreasing, The Cikapundung River, is an alternative source for raw water, is being used as primary raw water for several decades in Bandung. Using statistical method, research has shown that the distribution of minimum flow of the three flow stations could not meet the total demand in dry months. Station Cigulung-Maribaya, Station Cikapundung-Maribaya, and Cikapundung-Gandok usually experienced an extreme dry condition in September. The minimum flows for those three stations for a 20 years repeating period are 0.226 m3/sec, 0.893 m3/sec and 0.336 m3/sec, respectively. The dam that has been constructed up stream of The Cikapundung River is expected to increase the capacity of Station Maribaya up to 0.608 m3/sec, which could then impact the total raw water supply for Pakar Water Treatment Plant. Concurrently, the construction of dam at Station Gandok is targeted to increase the raw water supply up to 0.604 m3/sec. Those means giving solution for migrating groundwater to surface water utilization.Keywords: daily minimum flow, monthly minimum flow, reservoirPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3944[How to cite: Sabar, A., 2006, Prospek  Kontribusi  DAS Cikapundung  Memenuhi Laju  Permintaan Sumber  Air Baku  Metropolitan Bandung, Jurnal Media Komunikasi Teknik Sipil, Volume 14, Nomor 2, pp. 169-178]

To better understand their behavior and to find improvement to the current practice, experimental studies have been conducted using full-scale (3m × 3m) wall specimens, which represent simple housing wall panels. In this research, the performance of plastered confined masonry walls in resisting lateral loads was studied experimentally. Three wall specimens were constructed following general construction practice in Indonesia. All specimens were plastered on both sides. Model 1 was constructed without continuous anchorage, Model 2 with two continuous anchorages with 1m spacing, and Model 3 with two continuous anchorages with 0.5m spacing. The specimens were subjected to cyclic in-plane lateral loads. The parameters evaluated were damage pattern and failure mechanism, load capacity, stiffness, ductility, and energy dissipation. The study revealed that adding plaster improved the wall’s lateral capacity. The continuous anchorage shows less significant improvement on plastered walls compared to non-plastered walls, but still increased stiffness, ductility, and energy dissipation. The study verifies that having plaster and continuous anchorage improve structural performance while delaying damage. Analytical study reveals that all models have adequate capacity to resist the design seismic load based on the current code.

In this study, the analysis is performed using RANS, a computational fluid dynamics (CFD) simulation with faster computation time compared to other methods. OpenFOAM, an open-source software, is used to run the simulations. This study used a structured mesh with standard RANS k − ε turbulence model. Four symmetrical buildings with a scale of 1: 420 are used as the model of this study. Numerical modelling of different computational domain size and different degrees of fineness of the meshing is simulated to determine margin of errors. The result indicates that changes in computational domain has a significant effect on CFD analysis in lowering the error value in area with high flow speed ratio (U/U0> 1) to reach the acceptable error limit. Contrastingly, changes in the degree of fineness of the meshing do not give a significant change in error value. A relatively coarse meshing with fast computation time could give a similar result as A fine meshing model with longer computation time.

It is analyzed by linear elastic method so that it can’t describe the seismic behaviour of the structures. For that reason, the design of structure needs to consider performance based design. Irregularity of structure play important role for the results of Structure Performance. This paper uses five models of 20 storey reinforced concrete building with same height(76 m) and areas(750m2) with different plan configurations: rectangular, T, L, U, and H-shaped. Non linear time history method is used  to investigate the seismic behaviour of the structures, using finite model with ETABS2016. Dimension of structures are column (600 x1000 mm), shear wall (400mm), couple-beam (400x900 mm), slab (140mm). Recorded accelorogram used in this paper are Altadena, Array, Corralit, LACC, and Yermo because it has almost same earthquake mechanism, magnitude, and epicentrum distance, so that they are used as an artificial accelorogram that is synthesized using Wavelet Function according to SNI 1726-2012.Result shows that the story drift and plastic hinges for collapse prevention (CP) are: rectangular (story drift is 0.59% and amount of CP hinges are 8), H-shaped (1.58%/23), L-shaped (2.41%/30), U-shaped (4.59%/35), T-shaped (5.8%/58).

The compressibility rate of this soil is very height, with the depth of the soft soil of more than 30 meters from its surface. Based on “the worst case scenario” without any soil stabilization treatment, it was estimated that the soil consolidation rate would be 1.7 metre within 20 years period of settlement. In order to speed up consolidation process, the vertical drain method was applied. Design of pre loading technique as well as the calculation of distance between vertical drains is then demonstrated in this paper. It was estimated that the depth of vertical drain would be 18 metres, with the distance between vertical drains is 1.2 metres each; height of pre loading is 4.5 metres. With these design parameters, it was expected that the settlement process would be accelerated by 40 folds (235 months to become 6 months period). Keywords: Vertical Drain, Pre-Loading, Settlement, Consolidation, Sub-Grade. ABSTRAK Perbaikan sub-grade untuk menopang perkerasan lentur runway bandara Tampuling di Tembilahan, Propinsi Riau perlu dilakukan karena sub-grade nya terdiri atas lapisan tanah gambut dan tanah lunak. Tanah ini mempunyai kriteria sebagai tanah dengan tingkat kompresibilitas tinggi mencapai kedalaman 30 m. Berdasarkan skenario terburuk, setelmen konsolidasi tanpa ada perbaikan tanah (sub-grade) akan terjadi sebesar 1,7 meter dalam 20 tahun (235 bulan). Upaya untuk mempercepat konsolidasi dilakukan dengan memasang drainase vertikal (vertical drain). Perencanaan tinggi pre-loading, dan spasi drainase vertikal berikut kedalamannya mempengaruhi proses kecepatan konsolidasi dianalisa. Hasil perencanaan yang diusulkan adalah sebagai berikut; (i) kedalaman drainase vertikal = 18 m;(ii) spasi antar drainase = 1,2 m; dan (iii) tinggi preloading = 4,5 m. Setelmen yang direncanakan dapat dipercepat sebesar 40 kali dari semula 235 bulan menjadi sekitar 6 bulan.Kata Kunci : Drainase Vertikal, Preloading,  Setelmen, Konsolidasi, Tanah Dasar/Sub-gradePermalink: http://ejournal.undip.ac.id/index.php/mkts/article/view/3697[How to cite: Sandhyavitri, A., Wibisono, G., Juniati, S. dan Rioputra, M.D. (2008), Analisa Perbaikan Sub-Grade Runway Lapangan Terbang dengan Metode Vertical Drain (Studi Kasus Bandara Tempuling  di Tembilahan, Propinsi Riau), Jurnal Media Komunikasi Teknik Sipil, Tahun 16, Nomor 3, pp. 231-242]

Selain mendorong investasi swasta, strategi ini akan memperbaiki kualitas udara di pusat kota dan pemanfaatan kapasitas jaringan jalan. Jumlah pejalan kaki, kendaraan tidak bermotor dan angkutan umum akan mengurangi emisi dan konsumsi energi. Penelitian dilakukan pada proses evaluasi rencana perubahan jalur satu arah menjadi dua arah dan uji coba pedestrianisasi dengan piranti lunak EMME/2. Pengenalan lalulintas dua arah di jalan Abubakar Ali – Pasar Kembang serta segmen pejalan kaki di pusat kota akan mengurangi lalulintas menerus dan memindah lalulintas ke sistem loop yang dikenalkan sekitar pusat kota. Skenario tersebut mengurangi 20% kendaraan-km dan 13% kendaraan-jam. Meskipun kecepatan kendaraan berkurang dari 25,5 km/jam menjadi 23,5 km/jam, skema ini tetap menunjukkan penghematan BBM tahunan sebesar 251.892 liter  atau setara Rp 453.266.302,00 dengan tingkat harga BBM saat ini. Skema ini akan mengurangi polusi udara di wilayah penelitian sebesar 13,04% - 15,69% serta peningkatan kondisi transportasi tidak bermotor.

Implementation of early release on reservoir routing requires an initial elevation that is different from the initial elevation in general. The aim of this research is to determine the new initial elevation to support early release operations for the Sadawarna Reservoir. This research was conducted by calculating return flood discharge and flood routing in reservoir with 3 (three) scenarios of initial elevation. The method used for analysis of return flood discharge is SCS (Soil Conservation Service). The reservoir routing method uses level pool routing with the HEC-HMS application. Initial elevation is determined by 3 (three) scenarios that started from initial elevation +75,25 masl, +77,00 masl, and +78,50 masl. The results of 3 (three) scenarios showed that the optimal initial elevation that can be used in early release operations is at an elevation of +77,00 masl. The results of the reservoir flood routing simulation with initial elevation resulted reduction flood discharge up to return period of 50 years and resulted in the fastest reservoir water level recovery

To overcome this problem, Semarang Government has implemented “One Way System” on the Indraprasta Street section without providing road partner. This study is intended to identify the effectiveness of this policy. The following streets were reviewed: Indraprasta, Imam Bonjol, Mgr. Soegiyopranoto, and Pierre Tendean. Further, the intersections which studied are Indraprasta-Imam Bonjol-Pierre Tendean and Tugu Muda. Traffic survey data were collected in the morning and afternoon peak hours. Manual Kapasitas Jalan Indonesia 1997 was used in the data analysis procedure. This short-term study was conducted by simulating the proposed scenario and compared with the existing situations.In conclusion, “One Way System” on Indraprasta Street section is assessed not effective due to its relatively small degree of saturation, while Mgr. Soegiyopranoto Street has a large degree of saturation. Therefore, the one-way system to Imam Bonjol Street and Mgr. Soegiyopranoto Street also needed to implement and form a “rotary link“. In addition, enacting contraflow for public transport on Soegiyopranoto Street and Imam Bonjol Street is necessary, also the arrangement of signals and geometric in the intersection that linked those three streets.

Sedimentation that occurs in each of the reservoirs would form a specific reservoir sedimentation pattern that is supposed to be similar because the hydrology and physiography conditions of the reservoir's catchment area are similar. This study aims to determine the dynamics of sedimentation patterns that occur in the dead storage for reviewing the characteristics/sedimentation regime of the two reservoirs. The analysis was carried out by processing bathymetrical data which were processed into a digital terrain model (DTM) using ArcGIS. Furthermore, the storage volume, sedimentation volume, storage percentage, and specific reservoir sedimentation rate are calculated. The results showed that the two reservoirs showed an increase in sedimentation volume each year so that the reservoir characteristic curve shifted from the plan graph. The dead storage capacity of Kedungombo Reservoir is 100% in 1989 to 43% in 2016 and 100% of Sermo Reservoir in 1997 to 58% in 2011. The specific reservoir sedimentation rate, i.e. 0.0031 and 0.0042 million m3/year/km2 for the Kedungombo Reservoir (between 1989 and 2016) and the Sermo Reservoir (between 1997 and 2011) respectively, indicating that the two reservoirs are in the same regime

Due to its high risk of structural failure, Bili-Bili Dam is classified as Class IV (Extreme). Recent developments have shown a decline in dam body stability due to seepage issues. If left unaddressed, this could trigger piping or even structural failure, posing a threat to the sustainability of the reservoir's functions. The objective of this study is to evaluate the safety factor (SF) of the main dam, right wing dam, and left wing dam as an integrated structural system of Bili-Bili Dam. The approach combines both qualitative and quantitative methods, including engineering geological assessments and Geostudio SEEP/W to analyze seepage rates and SLOPE/W to evaluate landslide potential. The analysis results indicate that seepage discharge remains within acceptable limits, and the dam’s stability under Operating Basis Earthquake (OBE) conditions is considered safe. However, under Maximum Design Earthquake (MDE) conditions, the slope safety factor does not meet the minimum standard required by SNI 8064:2016. Therefore, remedial actions such as reinforcement or retrofitting of the dam body are necessary.

These weaknesses can be avoided through the use of concrete block material as a positive contribution for this research. This article provides the efficiency in the use of concrete blocks instead of rubble stones in shallow foundation work, by highlighting work productivity and total cost of work for both materials. Data is collected on a wall fence foundation work which implemented both materials successfully in Grogolan, Umbulmartani, Ngemplak, Sleman Yogyakarta Province. This research has revealed that the average productivity on concrete blocks and rubble stones is 0.799 m3/h and 0.590 m3/h respectively, in which there is a time efficiency that concrete block construction is 35,44% faster than that of rubble stone. Total cost of concrete block will be more expensive than rubble stone if the work volume is small, nevertheless it reaches a break-even-point at work volume of 11 m3, meaning that a cost efficiency of concrete block construction occurs if the work volume is more than 11 m3. Moreover, the implementation of concrete block has 4 intangible benefits i.e. saving space usage, minimum waste, ease of work, and more precise product.

Maximum grade and critical length by AASHTO and Bina Marga, the vehicle standard is not equal with heavy vehicle operating in Indonesia. The goal of research is to analysis the mulberry of maximum grade and critical length that are definite in the regulation and arranged by Bina Marga, to definite critical length for descend lane and ideal transition grade. From the velocity data when antrance and finished the slanting upward and the heavy of vehicle, it can calculate the critical length. While critical length of descend lane, it can calculate from the amount of maximum braking performed by vehicle, until no happen system braking is damaged. The transition length is definite from distance that’s needed by vehicle from the speed at the end of upward grade, until vehicle speed return to recovery. The results of this research denotes that critical length is relatively smallest than critical length that recommendation by Bina Marga. As consequency of this case, the maximum grade that’s recommended by Bina Marga should be decrease. The limitation of critical length descend lane is needed to avoid damaging of braking system of vehicle. The definition of minimum transition length is recommended to recover vehicle speed design from decrease speed because upward lane, in order to avoid traffic jam. Keywords : Vertical alignment, Critical length, Maximum grade, Transition grade, Heavy vehicle.   Abstrak   Dalam perancangan alinyemen vertikal dikenal istilah “kelandaian maksimum” dan “panjang kritis”. Dalam menentukan besaran landai maksimum dan panjang kritis oleh AASHTO dan Bina Mrga, kendaraan yang dipakai tidak sama dengan kondisi kendaraan berat beroperasi di Indonesia sekarang. Tujuan dari penelitian ini adalah untuk mengkaji besarnya landai maksimum dan panjang kritis yang telah ditentukan oleh peraturan dan tata cara yang telah dikeluarkan oleh Bina Marga, menentukan panjang kritis untuk jalur jalan yang menurun dan menentukan panjang landai peralihan yang ideal. Dari data kecepatan sebelum memasuki tanjakan dan sebelum akhir tanjakan yang diperoleh dari survai setat berat kendaraan kendaraan dapat dihitung panjang kritis. Sedangkan panjang kritis untuk turunan dapat dihitung dari banyaknya pengereman maksimum yang dilakukan oleh kendaraan sehingga tidak terjadi kerusakan sistem rem. Panjang landai peralihan ditentukan dari jarak yang diperlukan kendaraan dari kecepatan pada akhir tanjakan hingga kecepatan kendaraan kembali seperti kecepatan rencana. Hasil penelitian ini menunjukkan panjang kritis yang relatif lebih pendek dibandingkan panjang kritis yang disarankan oleh Bina Marga. Sebagai konsekuensi dari panjang kritis yang relatif pendek, maka landai maksimum yang ditetapkan Bina Marga juga harus diturunkan. Pembatasan panjang kritis untuk turunan juga diperlukan untuk menghindari kerusakan sistem rem pada kendaraan. Penentuan panjang landai peralihan minimum disarankan untuk mengembalikan kecepatan kendaraan yang telah berkurang akibat tanjakan menjadi kecepatan rencana aga tidak terjadi gangguan arus lau lintas. Kata kunci: alinyemen vertical, panjang kritis, landai maksimum, landai peralihan, kendaraan berat.

Groin will shift away flow. Area just downstream of groin structure will be occupied by low velocity flow hence there will be sediment deposition. Turbulence mechanism between primary flow region and groin field having important role in sediment exchange needs to be investigated. Instantaneous flow measurement was conducted in order to investigate turbulence relation between series groin under various groin spacing. Laboratory experiment employed turbulence flow having Reynolds number range between 31,935-32,500 and Froude number range between 0.051-0.053. A MicroADV 16-MHz was used to measure 3D instantaneous velocity. The experiment findings expressed that Reynolds stress involving vertical velocity  and    did not show any specific distributions except at the lowest measurement elevation, while Reynolds stress    showed specific distributions. Turbulence value difference between groin field and primary flow region at upstream of the groin field was significant. As the area was getting downstream, area containing high turbulence was wider. This work indicated that bed shear stress value  tended to grow at downstream area of groin field. High difference bed shear stress value  between primary flow region and groin field seized second groin field and third groin field.

Dalam studi ini, untuk mengukur kinerja dari campuran beraspal digunakan beberapa parameter Marshall, seperti Marshall stability, flow, Marshall Quotient (MQ), Void Filled with Asphalt (VFA), Void in the Mix (VIM) dan Void in Mineral Aggregate (VMA). Sedangkan untuk mengukur durabilitas campuran beraspal digunakan parameter Marshall Retained Stability. Campuran beraspal dibuat dengan mengacu pada 2 (dua) standard, yaitu yang pertama, SKBI – 2.4.26.1987 UDC : 625.75 (02), dimana campuran beraspal dipadatkan sebanyak 150 kali (75 kali per muka), untuk mendapatkan apa yang dinamakan campuran beton aspal (asphalt concrete/AC). Standard kedua yaitu standard baru Bina Marga (2001), dimana campuran beraspal dipadatkan sebanyak 2 (dua) fase, yaitu fase 1 dengan jumlah pemadatan sebanyak 150 kali dan fase 2 dengan jumlah pemadatan 400 kali. Hasil dari proses pemadatan dua fase ini adalah campuran beraspal hot mixture asphalt – percentage refusal density (HMA – PRD). Sesudah proses pemadatan, campuran beraspal kemudian disimulasikan dengan beberapa periode curing dan dua kondisi curing yang berbeda, yaitu curing di dalam dan di luar ruangan, dengan beberapa tingkatan suhu dan kelembaban. Hasil yang diperoleh dari studi ini mengindikasikan bahwa periode curing mempunyai pengaruh yang dominan terhadap kekuatan campuran. Sebenarnya faktor suhu dan kelembaban juga mempunyai kontribusi terhadap bertambah atau berkurangnya kekuatan campuran, namun hal ini tergantung dari lokasi dimana proses curing dilakukan dan tergantung juga pada pengaruh cuaca, terutama pada saat proses curing dilakukan di luar ruangan. Pengujian durabilitas campuran beraspal memberikan hasil bahwa semakin panjang periode curing dan semakin tinggi suhu di lokasi curing, maka campuran beraspal akan semakin awet (durable). Hasil lain yang diperoleh dari studi ini adalah campuran beraspal HMA-PRD menunjukan kinerja dan durabilitas yang lebih superior dibandingkan dengan kinerja dan durabilitas campuran beton aspal (AC).   ABSTRACT  The aim of this study was to provide up-to-date information about the influence of curing period and environmental factors, that are temperature and humidity, towards the performance and durability of asphalt mixtures. To measure the performance of the  mixture, several Marshall characteristics, such as Marshall stability, flow, Marshall Quotient (MQ), Void Filled with Asphalt (VFA), Void in the Mix (VIM) and Void in Mineral Aggregate (VMA) are used in this study, whereas Marshall Retained Stability is used to measure the durability characteristic of the mixtures. The mixtures are developed according to two standard specifications, that is, SKBI – 2.4.26.1987 UDC : 625.75 (02), the old specification, on which the mixtures, AC mixture, is compacted as many as 150 blows (75 times per face). Another specification used in this study is the new specification for hot mixture proposed by Department of Public Work (2001), on which asphalt mixture, named HMA-PRD, is compacted in two phases, that is, phase 1 and 2 with total 150 blows and 400 blows, respectively. After the compaction, the mixture then is cured in different curing period and in several conditions, that is, indoor and outdoor conditions with different levels of temperature and humidity.  The result indicates that curing period has dominant effect on the mixtures stiffness. Actually, temperature and humidity factors also contribute to the results; however, it depends on the location of the mixtures cured and also the climates. The durability test results that the longer the curing period and the higher the temperature are, the more durable the mixtures will be. Another result of this study is the new-specification mixture, HMA-PRD, is more superior than the old-specification mixture in stiffness and durability parameters.

Because of the importance of this function, it is necessary to collect accurate sign data in a spatial database. Currently, there have been many database developments for the management of traffic signs, but data collection is still done manually, by means of surveyors recording groups of traffic signs and entering them into the database. The difficulty faced is the time and accuracy of the surveyors when it comes to selecting groups of signs, this is due to the large number of groups/sub-groups of signs. This problem needs to be solved with the help of a sign group detection tool with an image recognition approach. This study aims to develop an image recognition method to extract photo geotagging information on traffic signs into spatial data and attributes of traffic sign groups. The object of the signs that are sampled are signs that are on roads with the status of provincial roads in the Special Region of Yogyakarta. The results showed that the machine learning-based image recognition accuracy reached 88.66%, further research is needed to improve accuracy by paying attention to the geotagging photo capture variable.

This research main aim was to analyze the characteristic of the PCP. PCP Super Cold Mix Asphalt was used for the experiment. The mixtures were compacted Marshall hummer in lab using, and plate compactor on site. It was obtained that: compaction temperature variation significantly affected the characteristic of the mixture. Compaction at 100°C and 150°C, met stability, porosity and VMA specification, but not for the VFB. It required more compaction energy. The stability of cold compacted mixture at the age of 1 hour gave 844.74 kg (min. 500 kg). Towards this value, at the age of 48 hours; 96 hours; 192 hours; 384 hours, respectively gave increase of stability of 102%; 140%; 183%; 187% and then constant. Cold compaction on site gave less performance with porosity values in a range of 4.585-8.22% (spec. 4% -10%), therefore the VFB is less than minimum 65% of VMA; the stability obtained was 1422.72 kg (>min 500kg) or 58% stability of the samples compacted in lab at the same 16 days of age where stability had become maximum (constant). Cantabro test result of the cold mix gave 100% weight loss (the sample disintegrated), meanwhile the hot mix only lost 7.56% from 16% max loss.

One of the most frequently employed methods to estimate the flood discharge in the ungauged basin is NRCS-CN. This study is aimed to determine the CN value with/without soil drainage capacity from the soil information in SPT Indonesia. The location used is Pataruman watershed by calibrating the simulation discharge results with the observed discharge. Soil conditions in the Pataruman watershed show that the soil texture has a fine texture (HSG D), a slightly fine texture (HSG C), and a slightly coarse texture (HSG A). The average composite CN in the Pataruman watershed without soil drainage capacity was 85.58 while soil drainage capacity was 81.01. The results of the analysis show that with/without taking into account the soil drainage capacity in the Pataruman watershed there is no significant difference in discharge with a relation coefficient of 0.734 (without soil drainage capacity) and 0.732 (with soil drainage capacity). CN calculations with/without soil drainage capacity are recommended for small watersheds.

In the last decade, Indonesia built above 50 dams. These dams majorly are built from geomaterial fill, including random materials. Random materials are very economical and have a low environmental bad impact, so their use tends to be maximized. Zones of random material often affect dam stability. Unfortunately, the evaluation of random material shear strength, a crucial parameter for dam stability analysis, is challenging. The large particles in random materials become an obstacle in shear strength tests using regular size apparatus. In Indonesia, there are several large-scale direct shear test facilities in laboratory and field to reliably test random material shear strength. Each laboratory test facility is owned by Technical Implementation Unit for Hydraulics and Water Geotechnics, PT. Indra Karya (Persero), and River Basin Organization for Bengawan Solo. The field test facility, called ILSDS, was devised by the Indonesian Geotechnical Inztitute in cooperation with Institut Teknologi Bandung and Universiti Teknologi Malaysia. This paper introduces these facilities and presents the results of ILSDS tests on random materials in Rukoh Dam, Aceh. The test results showed variability in shear strength as well as a unique behavior in the stress- strain relationship related to the random material content itself, such as large-grain rich or fine-grain rich materials. This large-scale testing is cost-effective, simple, and reliable. It is greatly recommended as a regular practice in a dam construction.

Nowadays, WPC board already been produced in Indonesia using Sengon sawdust and recycle HDPE plastic. Sengon sawdust was used as WPC since its availability from plywood production waste, moreover HDPE plastic considered had higher strength and more rigid than PET plastic. WPC occasionally being used as non structural material, moreover from previous study about mechanical properties of WPC, it was found that WPC Sengon has high shear strength around 25 – 30 MPa. These lead that WPC Sengon had a potential used as shear wall sheathing, thus additional research need to be conducted in order to study the type of bolt and diameter of the bolt can be used for these shear wall. This study aimed to investigate the dowel bearing of bolt using full hole method based on ASTM D5764 with type and bolt diameter as specimen variation. Two types of bolt were used in this study; stainless bolt and standard bolt with diameter each of 6 mm, 8 mm, 10 mm and 12 mm. According to ANOVA, there was insignificant result between stainless bolt and standard one, but there was significant result based on diameter of the bolt.

This situation requires an infiltration-based control system in accordance with the Low Impact Development (LID) concept. The infiltration box model is one solution to reduce inundation around road medians. This study aims to realize the infiltration box model, analyze the flow behavior of the model in the road median, and compare the model's performance under saturated and unsaturated soil conditions. The research method was carried out experimentally using flow in a laboratory flume channel. Based on the road area and return rainfall for a 2-year period, a discharge model of 0.109 l/s was used. The parameters analyzed included runoff discharge, infiltration discharge, and the volume of the box reservoir. The results showed that under saturated soil conditions, runoff reached 74.69% of the rainfall discharge, while infiltration and reservoir were only 11.20% and 5.89%, respectively. Under unsaturated soil conditions, runoff decreased to 46.65%, while infiltration increased to 30.43% and the box reservoir to 12.78%. Infiltration discharge in unsaturated soil was recorded at approximately 2.7 times greater than in saturated soil. These results demonstrate the influence of soil water content on the infiltration box performance model. Infiltration boxes should be integrated with other road drainage systems, including water pipes running under the road to the roadside drains.

When the negative impact comes to larger scale, macro decisions such policies supported by political issues should be intervented to minimize negative impacts and to develop a better transportation or a sustainable transportation in the future. It is an irony that most of professionals, technocrats, and scientiests related transportation in developing countries are still interested and focused in local issues of transportation phenomenon, model development for transportation planning and technical issues related to operational management analysis. Only a small group of them are interested in transportation impact studies for both local and larger area. It will be a rational justification to construct models to support decision making process in order to have a policy within line with sustainable environment which is not only useful for both local scale, but also larger scale (national and the earth).

This research will study the possibility of steel pipe pile as a replacement of massive reinforced concrete piles if there are available enough steel pipe piles. This research is aimed to study the behavior of single steel pipe pile Nailed-slab System on soft clay and the influence of pile length due to slab deflection and soil stresses. It was used the data from Puri (2015a) for a single massive reinforced concrete pile Nailed-slab. This massive reinforced concrete pile was replaced by a single steel pipe pile with similar and varied diameter which analyzed by the 2D finite element method. Results show that the steel pipe pile can be used as a “nail” at the Nailed-slab pavement system but by a larger dimension compared to the massive reinforced concrete pile. The maximum effective shear stress in soil did not reach undrained shear strength under a standard wheel load 40 kN. Generally, the soil was not failure.

But this method is not highly effective considering rainfall intensity is very high in the project location. Therefore, optimization needs to be done to obtain the most effective method in terms of cost and timely accomplishment of the access road. The optimization method is done by making a comparison matrix of the output results of the running simulation schedule on software. From the several methods proposed, the duration of completion, completion costs, and resource requirements are compared and scored to get the most optimized method. Other than that, carbon emissions resulting from each method are also compared. The optimization result concluded that boulder stone layer addition with optimum quantity in the embankment is the most optimal method considering the remaining time and encountering intensive rainfall. This optimized method can result in an accelerated construction duration of 140 days, cost efficiency of 11.46%, and a reduction in carbon emissions of 44% compared to the initial method. This optimization method is expected can be applied to access road embankment projects of soft soil areas in other locations, especially in the Kalimantan region.

However, the implementation of rigid pavement takes a longer time to reach its concrete strength until the road operation. Some industries have developed pavement from precast concrete panels to reduce construction time. This paper discusses the comparison of rigid pavement between precast concrete and conventional concrete. Two road sections are Jalan Margomulyo Surabaya using precast-concrete-pavement and Jalan Semarang-Jambu using conventional-concrete-pavement chosen as research objects. Cost, construction time, serviceability, and traffic performance are the four variables reviewed in this study analyzed using the Analytical Hierarchy Process (AHP) method with considers 15 competent experts as respondents. Based on the analysis shows that a road improvement project by using precast-pavement is more effective and efficient with a score of 58.42 %, while the score of conventional concrete is 41.58 %.

This rotational deformation occurs as an accumulation of bending deformation in beams and columns as well as shear deformation in the panel zone. The goal of this study is to analyze how cyclic non-linear deformation occurs in beam elements and zone panels. The 8-story steel moment resisting frame built on class D soil and designed for seismic design category D were used as model. Incremental nonlinear dynamic analysis was carried out using 20 earthquake ground motions that contained with and without pulse effects. This was done so in order to identify the median value and standard of deviation of the LS, CP, and collapse boundary conditions. Nonlinear flexure and shear deformations that occur in beam element and panel zone were explored. The results obtained show that the rotational deformation of the beam due to actual flexure is greater when compared to the rotational deformation at IDRmax reaches the first time LS and CP boundary conditions. The similar trend occurs in shear deformation of the panel zone.

Likewise, as the coastal city of Semarang in Indonesia has built some of the polder which has been in operation or under construction. To assess the success of the polder management, necessary for a study to determine the performance of the system in controlling the flood in Semarang. Assessment of performance of the system as a whole polder in this study used the concept of the Balanced Scorecard (BSC). The results of this study demonstrate the performance of the polder in Semarang is an ideal: Polder Tanah Mas (73.81 / 100), then Polder Banger (67.21 / 100), Polder Kali Semarang (58.70/100) and the Polder Tawang (58.65/100). The performance of the Polder system above can not be separated from the existence of an independent governing body and had been prepared much earlier. So the presence of the governing body needs to be prepared in the polder system development. To improve performance, the polder-existing polder in Semarang needs to be improved its performance by improving the performance indicators is still less based on this research primarily on indicators: financial, management agencies and learning and development.

This concrete is suitable for solving the concrete pouring in the narrow and congested reinforcement. Beams made of both self-compacting concrete and normal high-strength concrete are analyzed by MSC Marc / Mentat software. Steel is modeled by being embedded in concrete. The failure criterion of Linear Mohr-Coulomb is used for concrete and Von Mises for reinforcing steel, respectively. Concrete and the plate support are modelled by 3D solid elements. For the steel, the truss element is used. The contact analysis is implemented between beam and both steel plate and steel supports. The load-deflection curve for both concrete are almost the same as the results of the experimental curve. The results of the contact analysis also showed that there were contact and separation in the contact area. The shear retention factor value close to one meaning will restrain greater loads. The results of the study on the reinforcement ratio also showed a reduction of 70% and an increase of 70% when using minimum and maximum reinforcement, respectively. The larger concrete cover also reduces the load that the beams can restrain.

An important feature of quality assessment of a pavement management system is the ability to determine the current condition and to predict future condition of the pavement. In order to establish the structural capacity of the existing roads, accurate information of the layer elastic moduli and thicknesses are needed. The aim of this paper is to describe the potential technique of the Spectral Analysis of Surface Wave (SASW) method for assessing the dynamic stiffness of constructed pavements. The SASW is a non-destructive in situ seismic technique which is based on the dispersion phenomena of Rayleigh waves in layered media. A set of transient impact source is used to generate Rayleigh wave energy that propagates horizontally near the surface layer of the pavement. Through two vertical accelerometers, the motion of the wave at the range of each frequency is recorded. The phases differences from the cross-power spectrum is then unwrapped and the dispersion curve of the phase wave velocity versus wavelength are then generated. An inversion process is iteratively employed to confirm the experimental dispersion curve from the theoretical model established. The SASW field test in this study was utilized to collect data on flexible and rigid pavement. The wave velocity profiles had shown that the SASW method is able to detect all the distinct layers of pavement units. The dynamic elastic modulus of obtained were found to be useful in the assessment of Indonesian pavement system.Keywords: SASW, dynamic stiffness, flexible and rigid pavement systemPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3949[How to cite: Rosyidi, S.A.P, 2006, Kajian Metode Analisis Gelombang Seismik Permukaan (SASW) untuk Pengembangan Teknik Evaluasi Perkerasan Lentur dan Kaku di Indonesia, Jurnal Media Komunikasi Teknik Sipil, Volume 14, Nomor 3, pp. 224-239]

The smooth disbursement of advance payments greatly influences financial management, particularly cash flow and construction project performance. Research on the impact of advance payments on cash flow and project performance remains limited. Therefore, this study aims to fill that gap. This research identifies the factors that influence the smooth disbursement of advance payments and examines their impact on cash flow and project performance, based on previous literature. Data were collected through questionnaires using a Likert scale. The study employs a quantitative analysis approach using Partial Least Squares–Structural Equation Modeling (PLS-SEM) with the SMART PLS 3 software to evaluate the outer and inner models as well as the overall model fit. The findings indicate that the factors influencing the smooth disbursement of advance payments include the client’s financial strength, clarity of contractual agreements, and the contractor’s reputation. The impact of advance payments on cash flow involves ensuring timely payment for materials, labor, and equipment mobilization. Meanwhile, the impact on project performance includes efficient equipment mobilization, adherence to equipment specifications, and the reduction of cost overruns caused by fluctuations in material prices.

The crucial aspects are related to the decreasing reliability of supply to Situ Gede and increasing sedimentation accumulation. The research concerns with various aspects due to the Situ Gede conservation and restoration that is aimed to increase the potential uses, based on the quantitative and qualitative model by using optimization technique and Analitic Hierarchy Process (AHP). The optimization technique is applied in order to evaluate the amount of monthly  water availability within 3 scenarios i.e. tourism ounly (Scenario 1), tourism and irrigation (Scenario 2), and, tourism, irrigation and raw water (Scenario 3), respectively, based on the potency of Situ Gede itself, new additional supply from other sources, and additional supply from Galunggung Crater. In addition, based on simulation of accumulated sedimentation model, that is aimed to identify the effect of firm outflow change of Situ Gede Release, indicates the decrease of firm outflow around 0,5% annually. The priority order based on AHP evaluation shows that the the first priority is Scenario 1, the second is Scenario 3 and the third is Scenario 2. Those priorities based on various criterias such as Investment Cost and Operation Maintenance, Additional Supply Reliability to Situ Gede, and Sedimentation. Sensitiviy analysis is also applied based on the weight change of each criteria in performing the shift possibilities due to the priority order.

The dynamic response mostly depends on the characteristics of the slab and the velocity of the transverse load acting on the slab. This analysis uses 10 km/h, 20 km/h, and 30 km/h as the velocity of the transverse load, and 110 km/h as the comparing velocity. Results show that maximum dynamic responses for each velocity does not always occur on the center of the slab, so the characteristics of the slab may be vary. The dynamic response is closest to maximum when the velocity of the load is 110 km/h because it is closer to the critical velocity of the system which is 112 km/h. This analysis assumed the slab is used for the bus’ parking ramp. Thus with the 10 km/h until 30 km/h velocity assumption for parking ramp is still quite safe because the velocity is far below the critical velocity of the system. Also the dynamic response of the system is far lower than the maximum response of slab.
