POLA SEBARAN KEJADIAN LONGSORLAHAN DI KECAMATAN SOMAGEDE DENGAN SISTEM INFORMASI GEOGRAFIS
Abstract: Landslide is part of forming mechanism which dynamically changing. This aim of research is to identify spatial pattern of landslide occurences in Somagede district using field survey and GIS as tool of analysis. The surveys are focused on occurrence and footprint that can be identified. Based on field survey, there are 39 points of landslide occurences laid on 7 villages which have steep slope and very steep slope categories. Average neighbor analysis shows the clustering pattern of landslide in Somagede, where the value of Nearest Neighbor Ratio is 0.768496. This hypothesis is supported by the z-score value -2.77 and p-value 0.0057 which are statistically accepted. © 2015 GJGP UNDIP. All rights reserved.
ANALISIS SPASIAL PENGARUH KEBERADAAN PERGURUAN TINGGI UNIVERSITAS JENDERAL SOEDIRMAN (UNSOED) TERHADAP PERUBAHAN MORFOLOGI KAWASAN SEKITARNYA
Abstract: This research aims to analyze the morphology changes of area around the university. It’s very important because based on City Spatial Planning (RDTR) of Purwokerto in 2014-2034 decided University of Jenderal Sudirman (a.k.a Unsoed) as a center of educational services. It’s simultanly will increase the trade activities and services supporter of educational activities and residential, so it would increasing the intensity of activity that indirectly will affect the physical changes in the surrounding area. This research using spatial analysis GIS to determine the land cover/land use change, area of land conversion, changes of building density, and figure/ground analysis to see the morphology and pattern of developments area and proving the influences analysis of the university toward the changes in the morphology of the surrounding area. Based on the research results it can be known that The university (Unsoed) in Purwokerto has been influence significantly (more than 80%) against changes in the morphology of the area around the university (Unsoed) in Purwokerto, this can be proven by the findings from the study as follows: (1) The increasing of the area of built up land in the area around the university (Unsoed) especially at a radius of 500 m from Unsoed as big as 18.3% from the year 2003 to 2013. (2) The average of buildings density per year was increased by 4.93%. (3) The pattern of development area that tend to cluster around the neighborhood streets, along the primary collector street inclined the pattern of linier development and the development of area that make up such as octopus in the village Grendeng and Karangwangkal (4) The university (Unsoed) be one reason for the establishment of buildings in a radius of 500 meters from the campus as big as 81.2%. (5) In the village Grendeng and Karangwangkal where the location of campus is, greater influence than the village outside campus locations Unsoed namely Village Bancarkembar, Sumampir and Pabuwaran. © 2015 GJGP UNDIP.

PEMETAAN PERKEMBANGAN PERHOTELAN DI PUSAT PERDAGANGAN DAN JASA KOTA SEMARANG DENGAN SISTEM INFORMASI GEOGRAFIS
Abstract: The development in center of Peterongan-Tawang-Siliwangi (Petawangi) Trade and Services Area in Semarang City resulted a new growth of commercial center activity. Hotels as one of the potential trade and service components in the center of Semarang City. Developing hotels are due to the development from the activity of MICE (Meeting, Incentives, Conference, Exhibition) from effects of business activity occurring in Semarang City. Hotels in area of Petawangi have 70 percent of total income of hotel tax that has been received from the entire region in Semarang City. The purpose of this research is to track the development progress in the hotel in Central City of Semarang in Petawangi Trade and Services Area. This research using spatial approach with spatio temporal GIS method and qualitative analysis using snowball sampling data collection technique. The results found that growth of hotels are beyond the provision of the growth of demand hotel's room. Hotels populous spreads occurs in urban village of Sekayu and urban village Pekunden during year 2000-2014. © 2015 GJGP UNDIP. All rights reserved.
IDENTIFIKASI POTENSI MULTI-BENCANA DI KABUPATEN LANDAK KALIMANTAN BARAT
Abstract:One of the important regional issues and potentials is disaster sector. It is caused by disaster which is an event or series of events caused whether by nature or unnatural factor that bring damaged and loss. Landak regency is categorized as high risk category in a disaster-prone area index issued by the national disaster management agency. The aim of this research is to identify the potential of disaster-prone areas. The identification is based on the values of variables on some multi hazards that may occur and threat the Landak Regency. The research’s type is an explorative and evaluative research with qualitative and quantitative approaches.Technical analysis using GIS, scoring, and weighting of the existing variables potential disaster. For vulnerability variable, it was measured based on the existing physical aspects, such as land use, slope, and soil type. The results indicate that there are some potential hazards in Landak Regency that are potential to be disaster, such as floods, landslides, cyclones, fires, and forest-fires. Each potential hazards has different prone levels and different distribution area based on the risk assessment. © 2015 GJGP UNDIP. All rights reserved.
KONVERSI LAHAN PERTANIAN PADA KORIDOR JALAN SOLO-YOGYAKARTA DI KABUPATEN KLATEN
Abstract: This research aims to assess the conversion of agricultural land in the road Solo-Yogyakarta corridor during 1994-2013. It happens because the existence of Road Solo-Yogyakarta in Klaten Regency affect land use in the surrounding area. This research using spatial analysis method by interpreting the Landsat and ALOS satellite imagery, overlaying land use maps, and comparing the land use map and Spatial Planning Map (a.k.a RTRW) of Klaten. The results showed conversion of agricultural land during the years 1994-2013 was 424.82 ha, most of the land was converted into residential and industrial. The rate of shrinkage of agricultural land was 22.35 ha/year, while residential land increased by 19.84 ha/year. The greatest conversion of agricultural land was happened in the Banaran Village. Overall, land use which was not in accordance with RTRW was 69.15 ha (0.90 %).© 2015 GJGP UNDIP. All rights reserved.
EVALUASI CITRA WORLDVIEW-2 UNTUK PENDUGAAN KEDALAMAN PERAIRAN DANGKAL PULAU KELAPA-HARAPAN MENGGUNAKAN ALGORITMA RASIO BAND
Abstract: The development of remote sensing technology recently has produced satellites sensors with the capability to provide imagery options by a very high spatial resolution. One of the satellite imagery is WorldView-2 that has 1.84 meter of spatial resolution. Beside its very high spatial resolution, WorldView-2 also has at least 5 bands on visible. The capability of remote sensing for underwater detecting through specific depths and availability of its bands on visible, give more appropriate options to apply logarithm bands ratio on shallow water depth estimation. This research was purposed to analyze the capability of WorldView-2 imagery to estimate shallow water depth of Kelapa-Harapan islands by using bands ratio algorithm. There were six bands combination used in applying band 1 through band 4 of WorldView-2 imagery. Analyzing results showed that the best combination of bands to estimate the shallow water depth in the study area was the ratio between band 1 and band 3 by giving the value of R2 as big 0.067 with the average of error was 0.66 m. Ratio between band 1 and band 4 gave the value of R2 as big 0.55 of its regression to the field depth samples. While 4 others bands of combination ratio showed very low correlation to field water depth. © 2015 GJGP UNDIP. All rights reserved.
