Sumatran elephant is declared as critically endangered by IUCN since 2011. In supporting conservation efforts on sumatran elephant in its natural habitat, molecular data collection of their population needs to be done. Genetic source material is mostly obtained in its natural habitat is its dung/feces. Study on cytochrome B gene as genetic marker from sumatran elephant fecal samples can be done to get additional genetic data as a form of conservation effort. Primer optimization as genetic marker based on cytochrome B gene has been carried out as an early study on sumatran elephant genetics. Primer optimization program based on cytochrome B genetic marker from sumatran elephant fecal samples was under Higher Education Applied Research funded by The Ministry of Research, Technology, and Higher Education. DNA was isolated from fecal samples of captive sumatran elephants in Elephant Training Center, Way Kambas National Park. Primer optimization was done via amplification by increasing certain temperature. Specificity test was done to ensure that the primer only recognized sumatran elephant DNA. The best result was obtained with the annealing temperature of 52oC

Amphibian distribution on degradated habitat in Pasir Bintang and Manduriang districts of the Gunung Raya Wildlife Reserve, South Sumatra Province is caused by human activities, namely illegal logging and coffee plantations. Amphibians are one of the components that make up ecosystems that are very sensitive to environmental changes. This study aims to know the pattern of the amphibian species distribution on degradated habitat as a first step in conserving them. The method used is a line transect combination method with an encounter survey or Visual Encounter Survey (VES) with a time search of 3 hours in both aquatic and terrestrial habitats and the coordinates of the encounter are recorded. Trap by using a drift fence and pitfall traps at the affected location and also by using the interview method with the surrounding community and forest police. Determination of the distribution of amphibians is done by mapping the coordinates of the encounters that have been recorded using GPS with the help of the location of the coordinates on Google Earth into the amphibian distribution map. The results obtained are in the form of mapping the coordinates of amphibian encounters in the affected area. The conclusion of this study is the distribution of amphibian species in degradated habitat that have been encroached by illegal logging and coffee plantations are very few types and limited distribution due to habitat destruction and the small amount of food available.

Salt or sodium chloride (NaCl) is used in everyday life mainly to give food taste. Salt is hepatotoxic, so excessive use of salt has an impact on the liver. The liver is one part of the organ that has an important role in the body's metabolism, especially in neutralizing toxins. The liver is composed of hepatocytes. There are 60% hepatocytes of the total cells in the liver. Hepatocytes are the main cells responsible for the central role of the liver in metabolism. Liver function becomes very vulnerable to damage because it continuously neutralizes toxins. Such damage can occur and affect the structure and function of the liver. This study was conducted to determine the structural abnormalities of hepatocytes that occur in the liver of mice (Mus musculus) due to excessive salt consumption. The method used in this study was a CRD (completely randomized design) method consisting of 1 control group and 3 treatment groups by sodium chloride (NaCl) with 6 replications. The parameter in this study was the level of hepatocyte damage in the liver of mice (Mus musculus). Hepatocyte damage that occurred was observed through histological preparations with Hematoxylin Eosin (HE) staining. The results of this study indicate that hepatocyte cell damage in the liver of mice (Mus musculus) increases due to continuous administration of excess sodium chloride (NaCl).

Housing procurement for low to middle-income people in Palembang is carried out by the government and developers with the direction of housing development towards the outskirts of the city. One of the directions of development is the Talang Kepuh area, Ilir Barat 1 district. Housing development in this area is carried out in a wetland area where some of the condition of the area is swampland so that in its construction it must have its characteristics because the land has been piled up. In addition, the problem of housing development is the difficulty of the need for clean water. Simple housing design that is environmentally sound with rainwater harvesting system as an alternative solution to problems in water supply, so that it can meet the residential needs of the community. The results of the analysis discussion are outlined in the form of a simple concept of planning and designing a simple house with an environmental perspective. Rainwater harvesting is an important use to reduce excess surface runoff that causes flooding, land subsidence, and dryness of groundwater reserves. Where rainwater from the roof of the house will be dispensed into the distribution pipes which will then be forwarded and accommodated in water tanks. Meanwhile, if the excess water is accommodated, it will be dispensed to the retention pond. The calculation is done by calculating the discharge from the rainwater covering the roof of the house, then the volume of the water tank will be obtained to get the dimensions. After getting the dimensions of the water bath will be calculated the necessary costs. The costs calculated are excavation and backfill of soil, concrete materials, pipelines, and workers' wages. So that a water reservoir can be made with concrete material that will be used for water needs. The stored water will be used as raw water. For use as cooking or drinking water, further research is needed.

Infection is a disease that is easily found in tropical areas such as Indonesia. The causes of infection that are easily found include infections due to fungi. One of the fungi that causes many infections is the Candida fungus. Tropical drugs commonly used to treat cutaneous candidiasis include nystatin, clotrimazole, miconazole, ketoconazole and other azoles. However, antifungal drugs have limitations, such as severe side effects, poor penetration into certain tissues, and the emergence of resistance. To overcome the negative effects caused by these synthetic antifungal drugs, it is necessary to explore natural antifungal drugs. One of the plants that has the potential as a medicinal plant is the mango parasite plant (Dendrophthoe pentandra (L.) Miq) which is a parasitic plant that attaches to the host which has the potential as herbal medicine. Research on the potential of active compounds in the leaves of mango parasite (Dendrophthoe pentandra (L). Miq) as antifungals has been carried out from November 2020 to June 2021 at the Genetics and Biotechnology Laboratory, Biology Department, FMIPA Sriwijaya University. The purpose of this study was to obtain fractions that had antifungal activity, to obtain isolates that had antifungal activity, what active compounds were present in the leaves of the mango parasite as antifungal, and to determine the minimum inhibitory concentration of the fungus Candida albicans. Based on research that has been carried out with methanol, n-hexane and ethyl acetate extracts that are active as antifungals, namely n-hexane and ethyl acetate extracts with an n-hexane inhibition zone diameter of 12 mm while ethyl acetate is 10 mm. Then purification of the n-hexane and ethyl acetate fractions was carried out using gravity column chromatography and the n-hexane fraction obtained two pure compounds that were active as antifungals, namely isolate N-1 with a diameter of 12 mm and N-4 with a diameter of 10 mm. Two pure acetate fractions were obtained which were active as antifungals, namely isolates E-1 with a diameter of 10 mm and E 5 with a diameter of 12 mm. Furthermore, the results of the eluate were tested by MIC and thin layer chromatography (TLC). The MIC results on isolates N-1, N-4, and E-1 were able to inhibit at a concentration of 500 ppm and were classified as strong. Meanwhile, isolate E-5 was able to inhibit at a concentration of 1000 ppm which was classified as moderate. The TLC results showed color spots on isolate N-1 which were blue, namely terpenoids, while in isolate N-4 which was orange in color were alkaloids, while in isolate E-1, the color was phenolic yellow, while in isolate E-5, which was purple, it was group terpenoids. The results of the bioautography of isolate N-1 with R¦ value: 0.9, isolate N-4 with R¦: 0.6, isolate E-1 with R¦ value: 0.8, and isolate E-5 with R¦ value: 0,9.
