Acrostichum aureum L. is a fern from family Pteridaceae, commonly called as swamp fern or mangrove fern and usually found in mangrove, swamp or brackish area. It noted that heavy metal concentration was found in Acrostichum aureum, but distinction measure in each organs was unknown. This study was conducted to acquire information about heavy metal concentration in Acrostichum aureum, the differential expression of Mn and Cu concentration in each organs, and examine the potential of Acrostichum aureum as Mn and Cu bioaccumulator. Acrostichum aureum and sediment sample taken from Muara Angke Wildlife Reserve, North Jakarta which contaminated by heavy metal Mn and Cu. As a proponent data, Acrostichum aureum and sediment sample also taken from Gunung Kapur Ciseeng that assumpted as uncontaminated area. The methods used was descriptive with purposive sampling technique. The result showed that Acrostichum aureum was bioaccumulator for Mn with BCF average value 1.06. Organs with the highest Mn and Cu concentration was root. U-Mann Whitney test result showed that Mn and Cu concentration in each lower organs significantly different to the upper organs.

River is the most important things for the human life, one of the components environmental especially for whom whose living in the city and Ciliwung river is one of the major river beside of others 13 rivers. Bamboo trees, bananas, cotton, gempol and elo are the common flora were dominate plants along the riverbanks (gempol and elo taken from the local people words). Based from interview with some local citizens in the Ciliwung riverbank which pas through the district of Pangadegan (South Jakarta), Ficus racemosa L (elo tree) is the most important plant which can withstand river erosion and could maintained the riverbanks during flood and continued by taking sample that plant on that district for need of analysis and identification. From the calculation Gigantochloa apus types stake has the highest INP value to the over all plot of 65.43% while INP Ficus racemosa is still low, but Ficus racemosa can be one alternative plant for conservation in the Ciliwung river, because Ficus racemosa has strong roots. However the selection of other plants such as bamboo trees is more effective because it has fast growth. Therefore, by combining the types of plants that role as conservation may be a solution.

Borneo has wide land that support high biodiversity. One of them is Tanjung Puting National Park (TPNP), which have biodiversity such as terrestrial mammalian carnivore. Carnivore has a role to maintain its ecosystems. But, there are no data for population density of terrestrial mammalian carnivore. The object of this research is to find out population density of terrestrial mammalian carnivore in Camp Leakey, TPNP, Central Borneo. This research accomplished in September-October 2015 in Camp Leakey. Using line-transect sampling. Data collection was accomplished at 18.00-24.00 Central Indonesian Time (WITA) on eight transects with three times replication by direct surveys and indirect surveys. This research has obtained five species, malayan sun bear (Helarctos malayanus), sunda clouded leopard (Neofelis diardi), leopard cat, and group of civet, like small-toothed palm civet (Arctogalidia trivirgata) and asian palm civet (Paradoxurus hermaphroditus). Population density of each species from the highest to the lowest is 13,5 Individual of leopard cat/km2, 9,84 Individual of malayan sun bears/km2, 4,31 Individual of sunda clouded leopard/km2, and 3,65 Individual of civet/km2. Malayan sun bears, sunda clouded leopards and civets prefer to be in land forest. Leopard cats prefers to be in transition forest.

The increasing human activity makes the preference for fast food increases. However, some people do not pay attention to the hygiene conditions of food processed from food stalls. Food handlers, equipment utilization, food processing, clean water, and the packaging are the critical points of bacterial contamination. Escherichia coli is a bacterium that usually used as the indicator of food hygiene. The objective of this study is to examine the contamination of coliform bacteria, especially E. coli at two hospital cafeteria by using MPN method and questionnaire regarding the implementation of the basic principles of hygiene. Stages of tests performed that are the presumption test, confirmation test, complementary test, gram stain test, biochemical test IMViC and supported by a questionnaire. From the two locations tested, some samples showed positive result in a presumption test and confirmation test but negatively complementary to biochemical test. This indicates that the sample does not contain E. coli bacteria in food, but there is the possibility of Citrobacter. The negative results of the IMVIC test showed that it is possible bacteria found in the presumption test and confirmation test not E. coli and non-pathogenic bacteria. Based on the results of the questionnaire, most of restaurant owner has understood to served food. Food at the hospital X and Y cafetaria are safe to consume because it has a negative E.coli.

Excessive energi consumption play a role in increasing blood glucose levels (hyperglycemia), due to the inability of the hormone insulin to compensate the high blood glucose levels. Blood glucose receptor found in the hypothalamus of VMH (Ventro Medial Hypothalamus) and LH (the Lateral Hypothalamus) is able to detect and change the settings for the feeding activity. The aim of this study was to obtain the relationship between high sucrose feeding on male Wistar rats of behavior and activity. This method uses Wistar rats (Rattus norvegicus) as an animal model. Sixteen rats were grouped into 4 treatment groups. The first group was given additional feed 20% sucrose, the second group was given additional feed 40% sucrose, a third group was given additional feed 60% sucrose, and the last as a control group. This feed given continuously for 70 days.Observation of activities conducted using Opto-varimexÂ® auto-track system ver.4.31. The results showed an corellation between activity based doses of sucrose.

This study aims to find growth medium commercial yeast (S.cerevisiae) and determine the optimum composition of bioethanol fermentation. This research was conducted at the Laboratory of Bioprocess PPPTMGB â€œLEMIGASâ€ along May to September 2015. The method used is experiment using a completely randomized design consisting of two treatment. The first treatment is an alternative growth media utilization, namely, tofu liquid waste, coconut water and a mixture of both. The second treatment is the composition of the fermentation with sugar content of 100 ml, 150 ml and 200 ml with the addition of 10 ml starter in each experiment. Data of commercial yeast cell growth (S.cerevisiae) on alternative growth media were analyzed by Anova one way. The results showed that there was an interaction of commercial yeast cell growth (S.cerevisiae) on alternative growth media. Post-hoc test showed the alternative media that consists of a mixture of tofu liquid waste and coconut water produce the highest commercial yeast cell growth at 25,8 x107 with a 7.62 log value (cells/ml). The most optimum of bioethanol produced in the fermentation process is on sugar 100 ml by the addition of 10 ml starter acquire as much as 45 ml of ethanol content.

Antagonism is the interaction that occurs when a microorganism interfere with the growth of other microorganisms. One of the microorganisms that have antagonistic ability is yeast. The research aims to determine the ability of antagonism yeast derived from the leaves of teak (Tectona grandis) as an agent for controling mold from poultry feed is Aspergillus sp., Fusarium sp., and Penicillium sp. Tests carried out using the method of antagonism co-culture in medium Potato Dextrose Broth (PDB) during the four days of incubation temperature of 27-28Â°C. The results showed that yeasts have antagonism activity against Aspergillus sp., Fusarium sp., and Penicillium sp. shown by mycelial growth inhibition and sporulation. Co-culture method results obtained 5 potential yeast isolates (T3D2 DU 1.7, T4D2 WU2J2, T4D2 DU 2.1, T4D1 DU 2.1, T5D1 DU 2.2).
