Abstract

This research is aimes to know the effect of turmeric extract on broiler abdominal fat. Fourty eight broilerchickens strain CP 707 placed on 48 batteray cages and was randomized, then were acclimated during 1 week.Those chicken was alloted into 4 groups, each group was treated as follows : T0 (control) : were not given turmerinextract; 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 thetreatment 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 dosewas ajusted to the chicken body weight. The chicken were feed with BR I and BR II. Food and drinking water weregiven in an ad libitum manner. Main parameter observed was abdominal fat weight, supporting parameter was bodyweight and food consumption. Data was analyzed by varians analysis with Split Plot Design and continued withDuncan Multiple Range Test. The result was turmerin extract influences broiler’s abdominal fat. Increase anddecrease of abdominal fat are comparable with chicken body weight. On chicken 1 – 4 weeks of age, 200 mg/kgBW/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.

Abstract

Reboisation is one strategy to anticipate global warming that most easily performed. This re-plantingactivity is very urgent to be conducted in mangrove areas, since the impact of global warming are very profound atthe coastal and lowland areas. Its implementation has been done, but failures are still high. One of the causes oftenfound in the field is pests. Its efficient and effective control are still faces various obstacles. Wideng (Sesarma) isvery often perform as pest to the mangrove propagules, therefore could affect the community structure. It is thereforeimportant to establish conceptual study and research on wideng control, especially those that are able to promoteparticipation and benefit the community. One potential control is to empower its natural predators, the mud crabScylla. The purpose of this research is to analyze the level of Scylla predation, namely of total prey consumed, preysize and prey density presentation. It is also intended to determine weight gain and predation behavior byScylla. Two units of the test cage were placed in the pond in Tapak Tugurejo Semarang with Complete RandomizedDesign (3 treatments and 5 replications). Data on predation tests are descriptively and statistically analyzed usingJMP 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. Scyllaperform no respecter of prey body size, since wideng of small body size (2-3 cm), preferably the same to themoderate 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 thepresentation of the feed lot at once rather than presenting a slightly but gradually. Finally, feeding on Scylla withwideng through cultivation, particularly in fattening purposes, using wideng is reasonable and flexible to be appliedfor fishermen. This concept, together with other control components (components of a dissertation study of theauthor), is very supportive on the wideng control whiles provide economic benefits to the society atonce.

Abstract

Some traditional medicinal plants are known to have efficacy as a medicine for diabetes. Active compoundsproduced by a plant can be derived from endophytic microbes that live in these plants. One way diabetes drugs workis to prevent digestion of complex carbohydrates into glucose so that glucose intake is reduced. Alpha-glucosidaseinhibitor is a compound that can prevent the digestion of carbohydrates, especially starch into glucose. This studyaimed to test the inhibitory activity of alpha gluosidase PR-3 isolate, an endophytic bacteria from Momordicacharantia. The results showed that the crude extract (supernatant) from PR-3 has the capability of the enzyme alphaglucosidase inhibition that is equal to 61.2% compared with positive control compound acarbose 1 mg / ml. Theresults also showed that the use of maltose as carbon source produce the highest an alpha glucosidase inhibitor(54,97%), followed by the starch (47.77%), glucose (31.97%), fructose (44.14%) and sucrose (27.7%).

Abstract

Alfalfa (Medicago sativa L.) is useful plant for treatment some diseases such as: cancer, diabetes, lupus, andhepatitis. Propagation of this plant in Indonesia face a problem which has no embryo. One method to propagate thisplant is by tissue culture or micropropagation. Callus induction is first step in micropropagation to produce calluswhich will be regenerated to become planlet. The aims of this research are to induce callogenesis from hipocotyl ofalfalfa with addition Benzyl Amino Purine (BAP) and α Naphtalene Acetic Acid (NAA), and to determine the propercombination of BAP and NAA to produce the optimal callus. The experiment has been conducted by using 12combination of BAP and NAA with Completely Randomized Design (CRD) in 4x3 factorial pattern by 5 replicates.Data were analyzed by ANOVA 95% Degrees of Freedom (DF). If there was significance result, it was followed byDMRT analyzed at 95 % DF. The result showed that combination of BAP and NAA was able to induce callogenesisfrom hipocotyl of alfalfa. The optimal callus was obtained in combination of BAP 0 ppm and NAA 2 ppm.

Abstract

Ecohydrology is the study on the interaction hydrological process or aquatic with biological dynamicspatially and temporarily. Ecohydrology promises to be a tool of the sustainable use of aquatic resources byecological analysis integrated with freshwater aquatic conservation. Methodologically, ecohydrology is amanagement 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, itrequires an understanding about the role of organism. Temporarily, it requires reconstruction on thepaleohydrology as a base of the water resource development that put global changes into account. Based on thesuccessful implementation of ecohydrological concept on Saguling Reservoir, it able to be implemented for anotheraquatic ecosystem.

Abstract

Supply of water into leaves depends on the existence of water in xylem. Root system of plants will be affectedfirst if the plants exposed to stress of water shortage. The structure of xylem vessels is an important factor indetermining the presence of embolism induced by drought and varies from one type to another. Research on cocoaagroforestry tree Gliricidia sepium is used as cover crops. The purpose of this study was to analyze changes in thestructure 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 displacementexperiment), which runs from February 2007 - February 2008. Cacao tree used in this study was 5 years old, while6-year-old G.sepium tree. Location of the experiment were divided into six plots comprising three control plots andthree plots roofing. Each plot was taken six and three cacao trees G.sepium tree, where each tree root system wastaken 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 ofxylem cells and xylem vessels, root diameter hole and G.sepium cocoa. However, structural information can beobtained 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 ± 0.70while in the root G.sepium ± 0.49. Average diameter of the root xylem cells cocoa ± 1 μ in diameter, length 50-10μm ± vessels and vessel diameter hole ± 0.25 μ. Meanwhile root xylem cells G.sepium shows average diameter ofthe root xylem cells is 1-3 μ, ± 15-25 μ long vessels and vessels holes ± 0.5 μ rang
