Abstract

ABSTRACTHigh Energy Diet to Develop Obese Animal Model in Cynomolgus Monkeys (Macacafascicularis). Obesity is a primary predisposition for diseases such as metabolic syndrome(insulin resistance, blood lipid abnormality, and hypertension), type 2 diabetes, andcardiovascular disease. The effort to overcome obesity is needed by understanding thedevelopment of obesity. Therefore, it is urgent to carry out preclinical trials by using an obeseanimal model however it is still limited. The objective of this research was to study the effect ofhigh energy diet with animal fat and soluble carbohydrate to produce obese cynomolgusmonkeys (Macaca fascicularis). Animals used in this study were 15 adult males dividedequally into three treatment groups and were given diets for 4 months. The 3 groups were 1)receiving diet A consists of beef tallow without egg yolk; 2) receiving diet B consists of beeftallow and egg yolk, (energy 4,207 cal/g, fat 19.62%, and starch 60.34% in both first two diet) 3)receiving diet C consists of monkey chow as control (energy 4,330 cal/g, fat 5.55%, and starch51.38%). Measurement were taken every four weeks for body weight, crown rump length, hipdiameter, abdominal skin thickness, body mass index (BMI), nutrient consumption anddigestibility. Results showed that animals received diet B had significant increase in bodyweight and BMI at week 4 and 8. Hip diameter and abdominal skin thickness were significantstarting at week 4 in animals receiving diet with egg yolk (p<0.05) compared to the other twogroups. Protein consumption and digestibility in group with diet A and B was lower (p<0.05)compared to control animals. However, digestibility for dry matter, fat, starch and energy wereabout 90%, meaning that the rations were considered adequate in developing obese monkey.The diet formula containing tallow and egg yolk increased body weight based on BMI criteriaabove 25 kg/m2.Key words: obesity, cynomolgus, egg yolk, body mass index, digestibility

Abstract

ABSTRACTPerifiton is one community of organisms that can adapt and thrive in the river, and relatively settled in one location. Riparian vegetation in the Mountain Halimun-Salak National Park could be expected to affect the community structure of periphyton. The purpose of this study was to identify the community structure of periphyton on different vegetation canopy coverage, to analyze relationship between the communities structure of periphyton and upstream Cisadane water quality conditions, and to determine water quality based on perifiton community. There were three sets three stations based on canopy coverage (80%, 60%, dan 40%). The results showed two groups of stations, the high canopy coverage (80%) and the low canopy coverage. The highest perifiton abundance was found at stations low canopy coverage, that dominated by Bacillarophycae, Pennales order, especially Navicula with higher rate of succesion than the higher canopy caverage. Abundance of periphyton of low canopy coverage was affected by ammonium, turbidity, and water current. Furthermore, in stations high canopy coverage it was influenced by orthophosphate and currents. As a whole, the periphyton community at upstream of Cisadane indicated a good condition of water quality.Keywords: canopy, periphyton, succession rate

Abstract

Effect of habitat and altitudinal changes on the distribution of bats in Gunung Ciremai National Park, West Jawa. We investigated the bat community in its density and diversity between primary forest, secondary forest, shrub and pines in Gunung Ciremai National Park. This paper discuss the impact of these nature changes on the bat community along this national park. Our data showed a relationship between distribution of each bat species with habitat changes andaltitudinal gradients between 500-600 and 1100-2100 m above sea level. The distribution of bats according to their habitat and altitude in this study is parallel with some other previous studies. The results indicated that both habitat and altitidinal differences are important factors in influencing the distribution of each bat species. Although forest and disturbed areas provide food and shelter for support many of these bats species, it is urgent to maintain and improve the quality of the forests in this important national park.Keywords: Gunung Ciremai, bats, forests, disturbed areas, altitudinal.

Abstract

ABSTRACTPyrene is a high molecular weight chemical compound belongs to polycyclic aromatic hydrocarbon (PAHs) group that are difficult to degrade by environment. Biodegradation techniques using indigenous marine bacteria are used to be as an effort to reduce pollutants that are carsinogenic. The objectives of this research are to screen of 18 marine bacteria isolates qualitatively by sublimation method and quantitatively by growth test and to optimize degradation activity of marine bacteria isolates by pyrene concentration and cell concentration. Identification by 16S rDNA and phylogenetic tree analysis were conducted to determine the molecular basis of bacterial identity. The result of sublimation showed that 15 isolates were positive result for pyrene degradation and classified to 3 groups. The first group consisted of 5 isolates that can produce clear zone, while the second group are 5 isolates with isolate color changes. The third group have both of activities. Growth test showed that isolate LBF-1-0132 has high potency to degrade pyrene compound. Isolate LBF-1-0132 is capable of degrading pyrene compounds optimally at concentration of 600 ppm and optimum cell concentration of 20. Based on 16S rDNA gene analysis, isolate LBF-1-0132 is Pseudomonas aeruginosa with 98% identity.Keywords :pyrene, marine bacteria, optimization, 16S rDNA identification
