Skreening Potensi Antibakteri pada Beberapa Spesies Rumput Laut terhadap Bakteri Patogen pada Udang Windu
Izzati, Munifatul -
biologi
Antibacterial activity of several local seaweeds has been screened. Most of these seaweeds species show
antibacterial properties against pathogenic bacteria from species of Vibrio and Pseudomonas. The activity of
seaweeds extracts were determined by type of solvent used in extraction. Respond of each pathogenic bacteria were
also different to each type of extract. Most seaweeds show stronger activity against Pseudomonas rather than Vibrio.
Caulerpa and Padina were more active against Pseudomonas compared to Sargassum and Gelidium. Compared to
other seaweeds, Sargassum and Gelidium were more active against Vibrio. It is predicted that Sargassum is the the
most suitable to be used in polyculture with tiger shrimp (Peneaus monodon), as this is the most active against the
most dangerous pathogenic bacteria, Vibrio harveyi. Beside that, the active component of Sargassum is solved in
water, therefore will be easier to diffuse into shrimp pond.

Calophyllum inophyllum L., In Silico, Molecular Docking, Protein U Virus, Retroviruses
Retroviruses are a type of positive-sense RNA virus single-stranded with DNA intermediates and as obligate parasites that target host cells. The principle of DNA replication of retorvirus is not in a regular pattern but in an inverted pattern. Therefore, a study was conducted to find candidates for natural compounds from the seeds of the plant Calophyllum inophyllum L. and found that the most potential as a candidate for AIDS drugs was Calophyllolid. However, further research needs to be done and needs to be considered. This is because the binding affinity number is too small. Based on the Lipinski test, Calophyllolid does not meet all Lipinski's rules so that its use as a drug will be used by injection or other means than oral. In the toxicity test, Calophyllolid has the same value as the other 3 compounds, so a special test is needed to eliminate some of the possible carcinogenicity.

Freshwater sponges are animals from the Porifera phylum that live in freshwater. The sponge used is Oncosclera asiatica was taken from Kali Porong, East Java. Seventeen isolates of bacteria have been obtained from isolation. Antibacterial potential testing was performed by paper disc inhibition assay using Escherichia coli and Staphylococcus aureus as pathogenic bacteria and amoxicillin as a positive control. The antibacterial activity test showed that four isolates have the potential activity. The isolates with the highest inhibition zones were identified using a 16S rRNA.The results of BLAST showed isolate number 2 was Pseudomonas moraviensis with 99.51% similarity. The phylogenetic tree analysis was build using the MEGA X program. The results of the phylogenetic tree analysis showed that P.moraviensis had a bootstrap value of 100% with a genetic distance value of 0.001. P. moraviensis isolates screened for the presence of Non-Ribosomal Peptide Synthetase (NRPS) gene by A2gamF and A3gamR primers. The amplification result from NRPS gene showed positive meaning that P.moraviensis genome contained NRPS gene.

Binahong (Basella rubra L.) is a plant medicine consisting secondary metabolites which have virtue as
medicines for several diseases that could also be used as coloring agent. The medicine compounds in secondary
metabolites could be extracted from callus. Sucrose is one of the components that build MS (Murashige & Skoog)
medium. Sucrose is important in in vitro culture, it functions as carbon and energy source for explant to grow. The
purposes of this research are to study the effect of sucrose in MS medium towards B. rubra L callus formation and
growth; to find the optimum sucrose concentration for callus B. rubra L formation; and also to find the fastest
initiation time to produce callus crumb. This research uses Complete Random Design (CRD) single factor method,
i.e., sucrose concentration of 0 g/l, 10g/l, 20 g/l, 30 g/l, 40 g/l with five repetitions. The data is analysed with
Analysis of Varian (Anova) and if a real difference is found the analysis is continued with Duncan Multiple Range
Test (DMRT) with significancy level of 95%. The results show that various sucrose concentrations in MS medium
influences callus B. rubra L induction. The highest sucrose concentration, i.e. 40 g/l, which was added into MS
medium, could induce the maximum callus wet-weight of 1,69 g and the fastest callus initiation time of 4,8 day.

Darmanti, Sri -
biologi
Penelitian ini bertujuan mengkaji pegaruh IAA, GA dan kombinasi keduannya pada berbagai tingkat
konsentrasi terhadap perkembangan daun Acalypha indica L. Rancangan acak lengkap pola faktorial digunakan
dalam penelitian ini. Faktor pertama berupa variasi konsentrasi IAA (0, 10, 30 dan 50 ppm), faktor kedua berupa
variasi konsentrasi GA (0, 10, 30 dan 50 ppm). Data kwantitatif diuji dengan ANAVA, dilanjutkan dengan DMRT
pada taraf uji 5 %. Struktur anatomi didiskripsikan dari preparat penampang lintang lamina daun.
Hasil penelitian menunjukkan bahwa perlakuan IAA, GA dan kombinasinya tidak mempengaruhi struktur
anatomi daun Acalypha indica L. Tebal helaian daun Acalypha indica L. turun dengan perlakuan IAA, GA dan
kombinasinya. Penurunan tebal daun pada perlakuan dengan GA disebabkan oleh penurunan tebal jaringan palisade
dan jaringan bunga karang, sedang pada perlakuan kombinasi IAA dan GA sebagian besar disebabkan oleh
penurunan panjang sel palisade.

Supply of water into leaves depends on the existence of water in xylem. Root system of plants will be affected
first if the plants exposed to stress of water shortage. The structure of xylem vessels is an important factor in
determining the presence of embolism induced by drought and varies from one type to another. Research on cocoa
agroforestry tree Gliricidia sepium is used as cover crops. The purpose of this study was to analyze changes in the
structure of xylem vessels including area ratio, diameter and hole diameter of cacao root xylem vessels and G.
Sepium in drought conditions.
Drought stress on the cacao tree and G.sepium performed using EFT systems (throughfall displacement
experiment), which runs from February 2007 - February 2008. Cacao tree used in this study was 5 years old, while
6-year-old G.sepium tree. Location of the experiment were divided into six plots comprising three control plots and
three plots roofing. Each plot was taken six and three cacao trees G.sepium tree, where each tree root system was
taken three pieces with diameters of 3-5 mm at 20 cm soil depth.
Research results showed that drought stress during 13 months did not affect xylem area ratio, diameter of
xylem cells and xylem vessels, root diameter hole and G.sepium cocoa. However, structural information can be
obtained from the root xylem of cocoa have a cell - more xylem cells and pore holes smaller than the root G.sepium.
This is shown by the average ratio of the area with an overall area of the root xylem (k) on cocoa roots are ± 0.70
while in the root G.sepium ± 0.49. Average diameter of the root xylem cells cocoa ± 1 μ in diameter, length 50-10
μm ± vessels and vessel diameter hole ± 0.25 μ. Meanwhile root xylem cells G.sepium shows average diameter of
the root xylem cells is 1-3 μ, ± 15-25 μ long vessels and vessels holes ± 0.5 μ rang

Water quality, plankton, bioindicator, Sayung Coast
Sayung coast is a area with a growing residential, sea ranching, and industrial area. Those aspects produce create waste that could harm the environment, directly or indirectly. Plankton is a biologic component that is used to indicate the changes of water quality in waters that has been polluted. These goals of this research are to know the water quality in Sayung coast area from the abundance of the plankton, physical-chemical parameter of the water, and also the status of water saprobity. The samples are taken in July 2017 and April 2018, in Sayung coast waters, Demak. Plankton sampling and water from 5 sampling stasions are considered to represent the diversity of the plankton and water stability. Plankton is sampled using plankton net No.25, then preserved using 70% alcohol + 4% formaldehyde. The abiotic data measureted is nitrate content, temperature, pH, salinity, DO, and turbidity. Data analysis are done using Shannon Weiner’s diversity index (H’), diversty index (e), domination index (C), saprobic index. The result shows that there are 49 species of planktons are found, which are 38 fitoplankton, and 11 zooplankton. The highest group is Bacillariophyta which is 14,24%. The diversty index value of H’ 1,58 – 2,45; therefore the Sayung coast waters is catagorized as stable. The index value of e ranges from 0,64 – 1; index C values ranges from 0,08 – 0,22; and the saprobirity index value is in β-Meso/Polisaprobik to α-Mesosaprobik phase with a very light to very high pollution levels. The physical-chemical parameter analysis of Sayung coast waters in overall is still suitable to support plankton’s life.

Bioinformatics, Simulation, Blood Type Inheritance, Wolfram Mathematica.
Bioinformatics as an interdisciplinary science, combine biology, computer science, information technology, mathematics, and statistics in order to analyze and interprete biological data. Bioinformatics has been used for in silico analysis of biological questions using mathematical and statistical techniques. In silico analysis allows indirect simulation through a series of instructions put into a device, usually a computer. Nowadays, the simulation of biological aspects, especially genetics, with in silico method has been widely applied for several fields. The ABO blood type inheritance system in humans has rules that its mechanism can be applied into the Wolfram software programming, for example showing the possibility of blood groups being inherited from blood type O pairs with AB. The latest statistical data regarding the number of Indonesians who have reported their blood type has not yet reached 25% of the total population of Indonesia. Wolfram software is expected to be an accurate and fast blood type detector to record the entire population of Indonesia. The purpose of this study was to simulate Blood Type Inheritance with Wolfram Software Programming on ABO blood type inheritance data and see the suitability of the simulation results with real blood type inheritance data. The method used to simulate blood type inheritance is a survey of 12 families for the data of blood group, the next step is to enter the data one by one into the simulation model to observe the output results then matched with real data to determine the results of ABO blood type inheritance. Simulation of blood type inheritance can be done by programming the Wolfram Mathematica software and blood type data from 12 families can be simulated through the ABO blood inheritance system on Wolfram Mathematica, with details of the simulation predicting the blood groups of 2 families, simulation of 9 families according to real data, and simulation of 1 family does not match the real data.

A weed is a plant that is considered to be nuisance and unwanted plant in human-controlled settings,
especially farm field and garden. The weed that grow in surrounding of crop could decrease yield due to competition
occur between weed and crop on nutrition, sunlight and water. Organic farming system which has been developed
nowadays is an environmental friendly organic farming system. The objective of this research is to determine weed
competition on carrot using several kinds of organic fertilizer. Six treatments were used in this research, i.e., green
manure, combination of green manure and EM, EM alone and control (without manure and EM). The weed was
growth together with carrot for 3 months. The parameters are wet weight and dry weight of carrot per meter square.
The results show that manuring could increase weed competition which in turn wet weight and dry weight of carrot
are decreasing. The highest competition between carrot and weed occurred in the treatment of combination between
organic manure which combines with EM. The added EM on organic manure could increase weed competition on
carrot.

Not much has been done to observe the morphology of the anthers of various soybean cultivars. This study aims to observe the morphological characteristics of five soybean cultivars. The research was conducted in the research field and plant laboratory at the Faculty of Agriculture, Universitas Slamet Riyadi, Surakarta, using a completely randomized design. Five soybean cultivars were planted namely Argomulyo, Grobogan, Wilis, Anjasmoro and Hitam Malika. Observations on the seeds used, plant height growth, leaf morphology, flower morphology and anther conditions. Argomulyo, Grobogan and Anjasmoro cultivars have large seeds, weighing 100 seeds between 15-18 grams. Plant height growth occurs until the plant is 5 weeks old. The color and shape of the leaves of five one-month-old soybean cultivars are almost the same. At the beginning of the 2nd month, the leaves of the soybean plants turned dark green, which was evident in Grobogan and Hitam Malika cultivars. The crown color of the Black Malika soybean flower is dark purple, different from the other 4 cultivars with purple flowers. Cultivar Anjasmoro, 5 weeks old, reached 63 cm, the highest among the five cultivars planted. Each soybean cultivar has morphological characteristics in terms of plant height, shape, leaf color, flowers, pods, seeds and or anthers.

Pemotongan subsidi pupuk oleh pemerintah Indonesia membuat petani mencari alternatif pupuk yang relatif
lebih murah yaitu pupuk hayati. Pupuk hayati merupakan pupuk yang diinokulasi dengan mikroba yang bermanfaat
bagi tanaman. Penelitian sebelumya melaporkan bahwa Bacillus sp. DUCC-BR-K1.3 telah terbukti dapat melarutkan
fosfat, yang berperan dalam pertumbuhan tanaman, sehingga bakteri ini dapat dimanfaatkan sebagai agen yang
diinokulasikan dalam pupuk hayati. Pupuk ini dapat diformulasi dengan memodifikasi media pembawa yang
berpotensi yaitu tanah gambut dan padatan limbah cair industri rokok, yang mana memiliki kandungan bahan
organik pendukung viabilitas bakteri tersebut Penelitian ini bertujuan mengetahui viabilitas bakteri pada media
pembawa dan formula yang efektif sebagai dasar pembuatan pupuk hayati. Metode penelitian dilakukan dengan
Rancangan Acak Lengkap, di mana terdiri dari lima perlakuan yaitu F1 (100% tanah gambut), F2 (75% tanah
gambut & 25% padatan limbah), F3 (50% tanah gambut & 50% padatan limbah), F4 (25% tanah gambut & 75%
padatan limbah), dan F5 (100% padatan limbah). Variabel yang diukur adalah jumlah populasi bakteri per gram
dalam media pembawa selama masa penyimpanan 30 hari. Hasil penelitian dianalisis variansinya dengan ANOVA
kemudian uji lanjut dengan Duncan Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa perlakuan
F5 pada T1 (masa penyimpanan 10 hari), berbeda signifikan dengan perlakuan yang lain dengan viabilitas bakteri

Cellulose enzyme, Incubation temperature, Serratia marcescen
Enzymes are biocatalysts in living cells when cells metabolize. All living organisms are produced enzymes, both humans, animals, plants and microorganisms. One of the bacteria that has the potential to produce cellulose (EC 3.2.1.4) enzymes is Serratia marcescens. These bacteria can be isolated from water, soil and digestive tract. This research aims to find out the types of enzymes produced by S. Marcescens, to examine the effect of temperature and incubation time on selected enzyme activity. The type of enzyme test was qualitatively determined by S. marcescens growth on the amylolytic, cellulolytic, pectinolytic and chitinolytic selective medium based on the clear zone. This research was used a Completely Randomized Design (CRD). The first factor was the incubation time (T) which were 4 hours (T4), 8 hours (T8) and 12 hours (T12). The second factor was the treatment of incubation temperature (S) which were 40oC (S1), 50oC (S2) and 60oC (S3). Each treatment was repeated in 3 times. The data were obtained then analyzed using Anova (α = 0.05). If it is significantly different, furthermore proceed with the T test (BNT). The results showed that S. marcescens qualitatively produced only clear zones in the cellulolytic medium of 5.1 mm. The ANOVA results showed that incubation temperature (S), the interaction between incubation time (T) and incubation temperature (S) were did not have effect on cellulase activity, whereas incubation time (T) gives a significant effect on cellulase activity were obtained at the incubation time for 12 hours (T12) with a value of 0.27 U / mL

biologi
Aflatoxins are highly toxic secondary metabolies produced during the growth of several fungi, especially
Aspergillus flavus. AFB1 and AFB2 one of them which contaminates a wide variety of food and feed causing serious
health problem when consumed by human or animals. This research was aimed to study the potency of Lactic Acid
Bacteria (LAB) in the inhibition of Aspergillus flavus growth and the production of Aflatoxin B2. Three species of
LAB i.e. Lactobacillus delbrueckii , L. fermentum, L. plantarum were investigated for their potential in inhibiting
and degradation of Aflatoxin B2 as well as inhibiting fungal growth. The trial was designed into three variations of
each isolate by challenging the fungal culture, before fungal inoculation, at the same time as fungal inoculation and
after fungal inoculation. It was found that all the three species of LAB are potential microorganism to inhibit
fungal growth as indicated by the reduction of the dry weight of fungal mycelia compared with control.
Quantification of Aflatoxin B2 showed that L. fermentum gave the strongest degradation of Aflatoxin B1 during 15
days incubation, then followed by L. plantarum and L delbruekii with a reduction rate of 0,,2408 ppm, 0,3373 ppm,
0,6393 ppm respectively, compared with control these are significantly different. These result conclude that
Aflatoxin B2 can be degraded or prevented to be produced by A. flavus by applying LAB.

Corncob Hydrolyzate, Meyerozyma caribbica, Fermentation, Xylitol
Xylitol (C5H12O5) is a non-carcinogenic polyalcoholic sugar. Xylitol is beneficial for diabetics because it can be metabolized without insulin. Corn cobs contain 30% xylose which can be fermented into xylitol by microorganisms. Xylitol can be produced by fermentation of xylose and few microorganisms. Meyerozyma caribbica is a yeast that has been proven to produce xylitol and inhibitor’s resistant. The aim of this research is to test the xylitol productivity by Meyerozyma caribbica InaCC Y67 using corn cobs hydrolyzate and the effect of the volume of fermentation media on xylitol productivity by Meyerozyma caribbica InaCC Y67. The method was carried out by culturing Meyerozyma caribbica InaCC Y67 as a starter on YPD media. Fermentation using 100 mL Erlenmeyer with the variation of fermentation volume is 10 ml and 75 ml, agitation 175 rpm and 30 oC. Parameters were measured based on the dry weight of cells, xylose and xylitol. Data were analyzed using fermentation kinetics. The results of analysis showed that the higher xylitol production was found in the fermentation volume 75 ml with an efficiency value of 7,171%. The highest xylitol production was at the 48th hour with production value of 2.050 g/L. Results from research shows that Meyerozyma caribbica InaCC Y67 can produce xylitol with corn cobs hydrolyzate. The right volume of fermentation in the fermentation process can also increase the productivity of xylitol.

and the variance of log population density at time t and t +1 (log Nt and log Nt+1) for every three days (t).The value
of rs was associated with s in correlogram. Fluctuation population of the rice bug determined through concistency
periodicity and amplitude curve of the correlogram. The population distribution pattern was identified by means the
ratio between variance and the average of total number of rice bug.
The result showed that the population fluctuation of rice bug was predicted by the migration, from the
reservoir to rice crop and vice versa. The plots which were adjacent to refuge protected from insecticide sprays have
higher abundance of rice bug than the plots which were located far from the refuge. Based on the correlation
coefficient, the population fluctuation of Situ Bagendit rice’s plots has an oscillation trend. The corellogram curve
showed exogenous and irregular type. In the plots planted with Ciherang rice, the pop fluctuation was also
experience oscillations with corellogram curve shapes, it indicates endogenous and exogenous type with an irregular
periodicity. In the plots planted with IR64 rice, oscillation occur with the endogenous corellogram curve with nonstationary
and non-periodict type. The pattern of population distribution of rice bug in Kepitu Village was a
clustered distribution.

Pola Aktivitas HarianPasangan Burung Serak Jawa (Tyto alba) di Sarang Kampus Psikologi Universitas Diponegoro Tembalang Semarang
Hadi, Mochamad -
biologi
Burung serak jawa (Tyto alba) merupakan hewan nocturnal. Burung T. alba biasanya bersarang pada
bangunan tua dan gedung yang tinggi dengan menempati sarang yang sudah ada atau mengambil alih sarang yang
ditinggalkan burung lain. Kemampuan bersarang pada gedung dan bangunan ini menyebabkan T. alba mampu
menempati gedung di kampus Psikologi Universitas Diponegoro Tembalang Semarang. Sifat T. alba untuk
menempati gedung kampus Psikologi Universitas Diponegoro dapat mempermudah perkembengbiakan, namun
potensi untuk perjumpaan dengan manusia juga sangat besar. Penelitian ini bertujuan untuk mengetahui pola
distribusi waktu yang digunakan oleh Tyto alba untuk aktivitas hariannya. Teknik pengamatan scaning sampling
digunakan sebagai dasar penentuan alokasi waktu untuk aktivitas burung hantu T. alba seperti, terbang, bertengger,
berburu, istirahat, bercumbu dan bertarung. Pengamatan dilaksanakan selama 14 X 24 jam, dengan 12 jam hari
terang dan 12 jam hari gelap. Penentuan pola aktivitas harian dengan menghitung rata – rata total aktivitas T. alba
selama 24 jam. Aktivitas harian yang paling banyak dilakukan oleh pasangan T. alba adalah aktivitas istirahat (14
jam 44 menit) dengan puncak waktu istirahat pada siang hari. Waktu yang dihabiskan untuk istirahat T. alba betina
lebih tinggi (15 jam 53 menit). Alokasi waktu yang digunakan untuk bertengger T. alba betina (2 jam 56 menit)
sebagai bentuk proteksi terhadap sarang. T. alba jantan bertanggung jawab memberikan kebutuhan nutrisi pada T.
alba betina waktu yang digunakan untuk berburu (7 jam 40 menit). Pasangan T. alba melakukan aktivitas bertarung
secara bersamaan (5 menit) dan waktu untuk bercumbu (4 menit).

Asteraceae is one of the most diverse families in Angiosperms with an estimated of 23,600 species worldwide. One of the interesting place to explore the diversity of Asteraceae is Mount Lawu which has high potential for ecotourism. The newest track commonly used to climb to Mount Lawu is through Candi Cetho hiking track that was established in 2015. The study on the diversity of Asteraceae species on Candi Cetho hiking track has not been done before. The objective of this study was to explore the species diversity of Asteraceae and to determine their taxonomic relationship based on morphological characters. Plant samples were collected using explorative method along the hiking track, covering the altitude of 1,440 to 2,550 m above sea level. Identification of plant specimens based on morphological characters showed the existence of 13 species. Cluster analysis on 50 morphological characters was done using Euclidean distance and UPGMA method resulted in the recognition of two clusters. Based on the principal component analysis, the morphological characters which showed highest role in the grouping of Asteceae species into two clusters were the base of the upper leaf, flower color, and upper leaf attachment type.

The coastal area is a transitional ecosystem that is influenced by land and sea, which includes several ecosystems, one of which is the mangrove forest ecosystem. The area of the Bangka Belitung Islands Province has a coastal area with a very wide mangrove cover, with an area of around 273,692.81 Ha. The degradation of mangrove forests in Indonesia is caused by various factors, namely: the number of unconventional tin mining activities that are widely carried out by the community. For this reason, a management effort is needed that includes an ecological monitoring effort on the condition of the mangrove community in an area. The purpose of this study was to determine the health condition of mangrove forests in Takari Beach, Bangka Regency as the basis for determining sustainable mangrove management policies. This research was conducted in August-September 2022 at Takari Beach. The results obtained from this study are that Takari Beach has a cover percentage of around 39.20% to 44.52%, where at that location there are 5 species, namely: Rhizophora apiculata, Sonneratia caseolaris, Rhizophora mucronata, Avicennia alba and Avicennia lanata. The health condition of mangroves on Takari Beach is categorized as rare/damaged. These conditions can be influenced by human activities in coastal areas such as marine mining activities or changing natural factors such as temperature, salinity, pH, DO and others.

extract; T1 : were given turmerin extract 200 mg/kg BW/day; T2 : were given turmerin extract 400 mg/kg BW/day;
T3 : were given turmerin extract 600 mg/kg BW/day. Turmerin extract was given on capsul shape. Replication of the
treatment was 6 times. Long of the treatment was 2 steps, step I (L1) turmerin extract was given during 2-3 weeks (8
– 21 days age), step II (L2) the treatment was continued during 3 weeks (22 – 42 days age), turmerin extract dose
was ajusted to the chicken body weight. The chicken were feed with BR I and BR II. Food and drinking water were
given in an ad libitum manner. Main parameter observed was abdominal fat weight, supporting parameter was body
weight and food consumption. Data was analyzed by varians analysis with Split Plot Design and continued with
Duncan Multiple Range Test. The result was turmerin extract influences broiler’s abdominal fat. Increase and
decrease of abdominal fat are comparable with chicken body weight. On chicken 1 – 4 weeks of age, 200 mg/kg
BW/day turmerin extract and 400 mg/kg BW/day turmerin extract increase chicken’s abdominal fat. On chicken 4 –
7 weeks of age, 200 mg/kg BW/day turmerin extract increases chicken’s abdominal fat.

Inulinase (E.C.3.2.1.7) merupakan kelompok enzim hidrolase yang mampu menghidrolisis inulin menjadi fruktosa. Produksi fruktosa secara langsung dari inulin oleh enzim inulinase hanya memerlukan satu tahap reaksi enzimatis dan menghasilkan 90% fruktosa sehingga lebih efisien. Optimasi perlu dilakukan untuk meningkatkan produksi inulinase, antara lain dengan penambahan sumber nitrogen dan optimasi waktu inkubasi. Khamir merupakan salah satu mikroba yang dapat memproduksi enzim. Salah satu khamir inulinolitik yang berhasil diisolasi dari umbi dahlia yaitu Pichia alni DUCC-W4. Tujuan penelitian ini adalah mengetahui variasi konsentrasi NH4NO3 dan waktu inkubasi Pichia alni DUCC-W4 dalam memproduksi inulinase pada tepung umbi dahlia. Penelitian ini dilaksanakan di laboratorium mikrobiologi, Jurusan Biologi Fakultas MIPA Universitas Diponegoro. Penentuan aktivitas inulinase dilakukan dengan metode DNS. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan 2 faktor. Faktor I (P0, P1, P2, dan P3) berupa konsentrasi NH4NO3 yang berbeda yaitu 0,029mM; 0,05 mM; 0,1 mM; 0,15 mM dan faktor II (H1, H2, dan H3) berupa waktu inkubasi (12 jam,18 jam, dan 24 jam). Masing – masing perlakuan diulang sebanyak 3 kali. Data yang diperoleh dianalisis dengan menggunakan metode ANOVA. Aktivitas inulinase masing – masing perlakuan pada waktu inkubasi 12 jam yaitu 0,567 U/mL, 0,407 U/mL, 0,304 U/mL, 0,486 U/mL, pada waktu inkubasi18 jam yaitu 0,761 U/mL, 0,644 U/mL, 0,543 U/mL, 0,554 U/mL, sedangkan waktu inkubasi 24 jam yaitu 0,564U/mL, 0,567 U/mL, 0,529U/mL, 0,612 U/mL. Berdasarkan hasil penelitian menunjukkan bahwa penambahan konsentrasi NH4NO3 pada medium produksi dan perbedaan waktu inkubasi tidak meningkatkan aktivitas inulinase Pichia alni DUCC-W4.

Sumber pemanis alami alternatif yang aman bagi kesehatan dapat diproduksi dari inulin dalam umbi dahlia (Dahlia variabilis Willd.) dan dapat dihidrolisis dengan inulinase dari Pichia alni DUCC-W4. Peningkatan produksi inulinase dapat dilakukan dengan menambahkan sumber nitrogen organik berupa pepton ke dalam medium. Hasil penelitian menunjukkan aktivitas inulinase tertinggi sebesar 1,237 IU/mL (P2T3), aktivitas invertase tertinggi sebesar 1,568 IU/mL (P2T3) dan aktivitas katalitik inulinase sebesar 0,824 IU/mL (P2T2) diperoleh melalui rasio S/I dengan membandingkan aktivitas invertase (S) dan aktivitas inulinase (I). Kesimpulan dari penelitian ini adalah penambahan pepton dengan berbagai konsentrasi (0%; 0,5% dan 1%) dan lama waktu inkubasi (12 jam, 18 jam dan 24 jam) tidak meningkatkan produksi inulinase Pichia alni DUCC-W4.

Phenologi, beans, climate change
Climate change is a condition characterized by changing world climate patterns which results in erratic weather phenomena. Altitude is one of the climate control factors that have a strong influence on air temperature. There is a correlation between changes in air temperature and altitude in Indonesia. The increase in altitude causes the air temperature to decrease and the O2 content is getting thinner. Altitude also affects the biophysics and reproduction of agricultural plants a lot, which includes the response of a decrease in temperature to the growth of agricultural plants and their production. This study aims to determine the effect of climate change on the flowering phenology of green beans (Phaseolus vulgaris L.) and the diversity of insect pollinators. Sampling was done by purposive sampling to collect flower data while Scan sampling was used to collect insect data. Samples were taken as many as 24 bean plants from the population at each location. There are six locations, namely 50 m asl, 200 m asl, 400 m asl, 600 m asl, 800 m asl, and 1,000 m asl. Plant parameters observed were plant height, number of leaves, number of branches, number of flowers, size of flowers and time of bloom and diversity of insect pollinators. The data obtained were analyzed using analysis of variance (ANOVA) and regression correlation analysis. The results of the analysis showed the influence of altitude on the time the flowers first appeared, the number of flowers and flower size. Beans grow and develop optimally at an altitude of 800 - 1,000 m asl.

This study aims to determine the histological features of the aorta and heart of male Rattus norvegicus after administration of cherry juice (Muntingia calabura L.) dan lakum leaf extract (Cayratia trifolia L.). The study used 30 male Rattus norvegicus L. in a Completely Randomized Design (CRD) consisting of 5 treatments with 6 repetitions, namely the control group (P0), the standard feeding group (P1), the hyperlipid feed group + 0.2 mL/200 g BB cherry juice (P2), the hyperlipid feed group + 40 mg / 200 g BB lakum leaf extract (P3) and hyperlipid feed group + 0.18 mg / 200 g BB simvastatin (P4). Hyperlipid feed was given during the treatment, which was 28 days. To obtain histological data, preparations were made using the paraffin method and then observed using a photomicrograph with 400x magnification and observing the aortic lumen, foam cells and intracellular accumulation of lipids in smooth muscle. Data were analyzed by ANOVA followed by Duncan Test at a significant level of 5%. The results showed that the addition of cherry juice and lakum leaf extract gave a significant effect on lumen width and thickness of the aortic wall (p <0.05), while on changes in heart muscle cell size no significant effect (p> 0.05). Histomorphometri showed the presence of foam cells and accumulation of smooth muscle lipids in the control and group treatments with hyperlipid feeding. The conclusion of this study was that the addition of cherry juice and lakum leaf extract can reduce atherosclerotic lesions by eliminating showed foam cells and prevent proliferating smooth muscle cells so the size of the aortic lumen width returns to normal, but didn’t cause enlargement of the heart muscle (cardiomegaly).

Ecohydrology is the study on the interaction hydrological process or aquatic with biological dynamic
spatially and temporarily. Ecohydrology promises to be a tool of the sustainable use of aquatic resources by
ecological analysis integrated with freshwater aquatic conservation. Methodologically, ecohydrology is a
management tool using organism to control hydrological process and using hydrology to control biota. Basically,
ecohydrology is water resource development that oriented on the capacity and ability to maintain it. Spatially, it
requires an understanding about the role of organism. Temporarily, it requires reconstruction on the
paleohydrology as a base of the water resource development that put global changes into account. Based on the
successful implementation of ecohydrological concept on Saguling Reservoir, it able to be implemented for another
aquatic ecosystem.

biologi
Gracilaria verrucosa merupakan salah satu dari 555 jenis rumput laut yang ditemukan di perairan
Indonesia. Merupakan alga merah yang thalusnya mengandung gel sehingga mempunyai kemampuan mengikat air
yang cukup tinggi. Besarnya air yang dapat diserap dan disimpan tergantung dari luas bidang penyerapan. Selain hal
tersebut, Gracilaria verrucosa seperti rumput laut umumnya mengandung makro mineral, mikro mineral, protein,
karbohidrat dan vitamin A dan C. Karena hal tersebut, maka Gracilaria verrucosa mempunyai potensi yang tinggi
untuk diamanfaatkan dalam bidang pertanian khususnya pada lahan dengan partikel tanah yang besar seperti lahan
pasir yaitu sebagai bahan penyerap dan penyimpan air sekaligus sebagai sumbur pupuk organik. Penelitian ini
bertujuan untuk mengetahui kapasitas penyerapan dan penyimpanan air oleh Gracilaria verrucosa pada berbagai
ukuran potongan. Penelitian menggunakan RAL, dengan perlakuan tunggal, terdiri dari 3 taraf perlakuan ukuran
potongan yaitu 0,25 cm, 0,5 cm dan 1 cm. masing-masing perlakuan dengan 3 ulangan. Kesimpulannya adalah
bahwa ukuran potongan berpengaruh terhadap kapasitas penyerapan dan penyimpanan air, kapasitas penyerapan
tertinggi pada potongan 0,25 x 0,25 cm dan kapasitas penyimpanan tertinggi pada potongan 1x1 cm.

Padina sp, Symbionic Bacteria and Hydrolase Enzymes
Marine organism is one of the riches in the ocean of Indonesia. The benefits of sea use for new products produced are widely used and have high market demand. Enzymes that have marine interests have unique properties and have good benefits for industry. This study aims to isolate the bacteria that have symbionts with Padina sp and determine the potential of the enzyme hydrolase produced by these bacteria. Isolation is done by the spread plate method. Pure isolates obtained were then tested for the potential of the enzyme hydrolase on selective media. Clear zone measurements are performed to determine which bacterial isolates are good for enzyme production. The results obtained by 6 isolates of pure bacteria, all of which include Gram negative bacteria that form bacilli. All isolates had the ability to produce different Protease, Lipase, Amylase and Cellulase enzymes. The enzymes obtained from these symbiotic bacteria are expected to be used for industrial-scale production in Indonesia. In addition, the presence of this symbiont bacteria is able to reduce the level of exploitation of Padina sp and contribute to preserving the marine ecosystem.

Metode Pengendalian Wideng (Sesarma spp) Hama Bibit Mangrove melalui Kegiatan Budidaya Kepiting Bakau Scylla spp
Hidayat, Jafron Wasiq
biologi
Reboisation is one strategy to anticipate global warming that most easily performed. This re-planting
activity is very urgent to be conducted in mangrove areas, since the impact of global warming are very profound at
the coastal and lowland areas. Its implementation has been done, but failures are still high. One of the causes often
found in the field is pests. Its efficient and effective control are still faces various obstacles. Wideng (Sesarma) is
very often perform as pest to the mangrove propagules, therefore could affect the community structure. It is therefore
important to establish conceptual study and research on wideng control, especially those that are able to promote
participation and benefit the community. One potential control is to empower its natural predators, the mud crab
Scylla. The purpose of this research is to analyze the level of Scylla predation, namely of total prey consumed, prey
size and prey density presentation. It is also intended to determine weight gain and predation behavior by
Scylla. Two units of the test cage were placed in the pond in Tapak Tugurejo Semarang with Complete Randomized
Design (3 treatments and 5 replications). Data on predation tests are descriptively and statistically analyzed using
JMP software, whereas the study of behavior was analyzed descriptively.
The results demonstrated that Scylla is able to prey and consume wideng namely the life ones. Scylla
perform no respecter of prey body size, since wideng of small body size (2-3 cm), preferably the same to the
moderate size (4-5cm) and large size (> 5 cm). The level of consumption gives a high weight gain for Scylla,
between 182 - 197% in just 6 days. In term of presentation of the treatment, showed that wideng really liked the
presentation of the feed lot at once rather than presenting a slightly but gradually. Finally, feeding on Scylla with
wideng through cultivation, particularly in fattening purposes, using wideng is reasonable and flexible to be applied
for fishermen. This concept, together with other control components (components of a dissertation study of the
author), is very supportive on the wideng control whiles provide economic benefits to the society atonce.

Kemelimpahan Jenis Gulma Tanaman Wortel pada Sistem Pertanian Organik
Utami, Sri -
biologi
Gulma merupakan tumbuhan alami yang mengganggu tanaman budidaya. Keberadaan gulma yang dibiarkan
tumbuh pada tanaman budidaya akan menurunkan hasil panen. Penurunan hasil panen oleh gulma disebabkan
adanya kompetisi yang terjadi antara gulma dengan tanaman budidaya.. Didalam upaya meningkatkan produksi
pertanian, umumnya petani menggunakan berbagai bahan agrokimia, bahan ini akan menyebabkan lingkungan
menjadi rusak. Agar lingkungan tetap terpelihara baik digunakan sistem pertanian organik yaitu suatu sistem
pertanian tanpa menggunakan bahan kimia yang bisa meracuni lingkungan. Salah satu jenis tanaman sayur yang
banyak dibudidayakan adalah tanaman wortel. Wortel sangat diperlukan karena banyak mengandung vitamin yang
sangat bermanfaat untuk kesehatan manusia. Gulma yang tumbuh di lahan wortel dapat menurunkan produksi
wortel. Penelitian ini bertujuan untuk mengetahui jenis-jenis gulma wortel dan kemelimpahannya pada sistem
pertanian organik. Lahan yang ditanami wortel gulmanya dibiarkan tumbuh sampai umur 3 bulan. . Dilakukan 4
macam perlakuan pemupukan organik yaitu pupuk kandang, pupuk hijau, EM-4 dan tanpa dipupuk Dilakukan
sampling gulma dengan mencatat jenis-jenis gulma dan menghitung jumlah individunya. Plot yang digunakan
berukuran 1 m x 1 m, dan dilakukan 3 kali ulangan. Dilakukan juga pengukuran faktor lingkungan. Dari hasil
penelitian diperoleh gulma yang dominan dan kemelimpahannya tinggi pada semua perlakuan adalah Drymaria
villosa dan Vernonea cinerea. Jumlah individu gulma paling tinggi didapatkan pada lahan yang dipupuk dengan
pupuk kandang, sedang paling rendah pada lahan tanpa dipupuk.

The breakwater of Tanjung Emas Seaport is designed to absorb seawave as well as increase ships stability.
Such water stability will trigger the light and small particles to deposite onto the bottom of the water body,
eventhough these are easily re-suspended and initiate to create turbidity. Turbididty is one factor affecting Mollusc
community. In facing the global climate changes, there will be a seriuos problem triggering the turbidity of the
seawater and so do the organims. Researh were aimed to study the benthic Mollusc community in different turbidity
levels. Justified ramdom sampling was applied in 14 stations. Community structure of the molluscs were analized
discriptively as well as through Shannon-Wiener (H’) and evenness (e) indeces.
Result showed that turbidity in PTES varies between 06,750 – 45,250 NTU. Such qualities were relatively
high range and can be tolerated by several given species, mainly Gafrarium tumidum, Nuculana acuta and Pyrene
sp. These three above species could live within such high turbidity levels, since some of material are part of their
diets without disturbing their respiration fuction. The highest diversity index H’ was 1,68 and found in Station 5,
which is in accordance with its highest turbididyt level 45,250 NTU. The smalest turbidity level occured in Station 8
and it was related to smaller diversity index (0,24). There was a tendency, the smaller the turbidity levels the smaller
the diversity indices. Such relatonship was consistence to the other three stations, namely 9,10 and 11. Exception
was found in Station 1, where different dominant species occured and diversity index was relatively high. It is
believed these are related to the presence of warm outlet of Indonesia Power sewage reaching 32,5 centdegree.

biologi
The existence of global warming caused the climate change such as the occurrence of long dry seasons
associated with ENSO (El Nino Southern Oscillation). The climatologists predict these events will occur more often
in the future. Cocoa plants require a relatively uniform distribution of rainfall in the year without a long dry season.
The existence of drought stress can affect the rate of decline in the growth and development such as leaf expansion
rate and decreased availability of nutrients in the root zone. This study aims to determine changes in specific leaf
area (SLA), the number trichomes and K + content of leaves of cocoa seedlings at different soil water content. This
study uses 36 cacao plants with 12-month-old were grown for two months on medium soil with soil water content of
75%, 50% and 25%. Parameters observed are the SLA, the number trikomata and K+ content of leaves. The results
showed the age of 12 months of cocoa seedlings planted on different soil water content showed differences in SLA,
trichomes and K+ content of leaves. The seedling grown optimum when planted on soil water content of 75%,
whereas in 50% soil water content began to decline in growth with decreasing SLA and without leaves trichomes.
The development and growth of seedlings declined sharply if planted in soil water content of 25%.

water hyacinth, compost, Rawapening Lake
High sedimentation and the entry of organik and inorganik pollutants, especially P and N, have led to the eutrophication of Rawapening Lake waters. These conditions triggered an uncontrolled booming of water hyacinth aquatic weed (Eichhornia crassipes (Mart.) Solms). The presence of water hyacinth triggers a significant loss of water compared to local weeds through evapotranspiration. The invasion of water hyacinth causes various problems, including depletion of water oxygen content which has an impact on decreasing fish production, damaging natural beauty, and also affecting public health. Many efforts to control water hyacinth in Rawapening Lake have been carried out both physically and by utilizing biological agents. One of the efforts to control the density of water hyacinth in Rawapening Lake is to use it as compost raw material. Water hyacinth contains various elements that are useful for making quality compost, including calcium (Ca), sodium (Na), potassium (K), iron (Fe), copper (Cu), and others. Water hyacinth root contains sulfates and phosphates, the leaves contain carotin and the flowers contain delphinidin-3-diglucosida. The various nutrients contained in water hyacinth make quality compost capable of meeting the nutritional needs of cultivated plants.

Perubahan Kandungan Ammonia, Nitrit dan Nitrat Dalam Air Tambak Pada Model Budidaya Udang Windu Dengan Rumput Laut Sargassum plagyophyllum dan Ekstraknya
Izzati, Munifatul -
biologi
Salah satu masalah penyebab kegagalan dalam budidaya udang windu adalah tingginya limbah organic akibat
sisa pakan yang tidak dikonsumsi. Akumulasi sisa pakan yang sebagian besar komponenya protein ini telah
mengakibatkan meningkatnya konsentrasi ammonia, nitrit dan nitrat dalam air tambak. Ammonia dan nitrit
merupakan bahan kimia yang dapat meracuni udang yang dibudidayakan. Model budidaya ganda udang dengan
rumput laut merupakan salah satu teknik untuk menurunkan kandungan ammonia, nitrit dan nitrat dalam air tambak.
Penelitian ini bertujuan untuk menguji penurunan kandungan ammonia, nitrit dan nitrat dalam air tambak pada
model budidaya udang dengan rumput laut Sargassum plagyophyllum dan ekstraknya. Penambahan ekstrak
Sargassum ini diharapkan dapat menurunkan pertumbuhan bakteri pathogen, sebagaimana sifat antibakteri pada
ekstrak tersebut. Model budidaya udang tanpa rumput laut maupun ekstrak digunakan sebagai kontrol. Rancangan
penelitian ini adalah acak lengkap (RAL), dengan 3 perlakuan dan 3 ulangan. Data yang diperoleh diolah dengan
ANOVA faktor tunggal. Hasil penelitian menunjukkan bahwa model budidaya udang dengan Sargassum dapat
menurunkan ammonia dan nitrit hanya sampai dengan usia pemeliharaan 8 minggu. Lebih dari usia pemeliharaan
tersebut, kandungan ammonia dan nitrit justru meningkat. Hal ini disebabkan karena Sargassum yang digunakan
mengalami kematian akibat turunnya hujan pada minggu ke-10. Penambahan ekstrak Sargassum tidak menimbulkan
perbedaan kandungan ammonia, nitrit dan nitrat apabila dibandingakan dengan kontrol.

Pembentukan Cabang Lateral Jarak Pagar (Jatropha curcas) Setelah Perlakuan Girdling
Darmanti, Sri -
biologi
Jarak Pagar (Jatropha curcas) merupakan tanaman yang pontensial sebagai sumber BBM yang terbarukan.
Oleh karena itu peningkatan produksi biji jarak diperlukan untuk mendukung produksi BBM ini. Karena buah Jarak
Pagar hanya terbentuk pada ujung batang dan ketiak daun yang dekat dengan ujung batang, maka jumlah cabang
yang banyak diperlukan untuk mendapatkan produksi biji jarak yang tinggi. Pembentukan cabang lateral dipengaruhi
oleh keseimbangan fitohormon antara lain sitokinin dan auksin. Girdling merupakan teknik untuk mengatur
keseimbangan kedua fitohormon tersebut. Pada penelitian ini, perlakuan girdling dilakukan terhadap tanaman jarak
dari stek yang berumur 5 bulan. Setiap perlakuan dengan 5 ulangan. Pengamatan dilakukan setiap satu bulan dan
diakhiri setelah 6 bulan. Dari hasil pengamatan diperoleh hasil bahwa perlakuan girdling berpengaruh memacu
pembentukan cabang lateral sedangkan tanaman control tidak membentuk cabang lateral sampai akhir perlakuan.

Drought stress will result in decreasing the rate of water absorption by plant roots. This decrease will result in
disturbances in plant growth, especially in a growing network includes the addition of Growth in dry mass, volume,
length or area of cells resulting from the interaction of processes in plants through photosynthesis, respiration,
transport, water relations and nutrient balance. Morphological and physiological responses of plants against stress
and patterns of plant adaptation to different environments is very important especially for the purposes of cultivation
and the prediction of the properties of responsive plant tersebut. Purpose of this research is to examine changes in
content klorofil a and b, and growth (number of leaves and plant height ) cocoa seedling age of 12 months at
different water stress.
The study was conducted in the village of Plana Banyumas, Central Java Province, which lasted from January
2007 to June 2008. Cacao tree used was 12 months in which the cocoa beans used for seeding of hybrid clones
derived from cocoa pods from the village of O, o Kulawi Donggala District of Central Sulawesi. Cocoa seedlings
were given three treatments of water stress that soil water content 75%, 50% and 25%. Observations of variable
chlorophyll a and b,number of leaves and plant height after one month and two months of stress.
The results showed drought effect on leaf chlorophyll content of seedlings of cocoa, where the plants grown on soil
water content of 50% have chlorophyll a and b are lower than those grown on soil water content 75%. The growth of
cocoa seedlings are best when planted with soil water content 75%, because the soil moisture content of 50% and
25% of the number of leaves and plant height decreased
