Sumatran elephants (Elephas maximus sumatranus) are one of four Asian elephants subspecies, which are categorized as Critically Endangered by the IUCN (International Union of Conservation of Nature) since 2011. Some factors that might drive this species into extinction ranges from wild attacks in the forest, habitat degradation due to land acquisition for plantation and development areas, and human slaughter because they regard these animals as enemies that sometimes enter community settlements. Elephants in Sembilang National Park is an interesting issue because it has not been registered as key species in Sembilang National Park, as well as no authentic evidence and official reports about the existence of elephants in the park. This paper proves the existence of elephants in Sembilang National Park, South Sumatra. The elephant documentation is in the form of photos and videos of 4 different elephant individuals, footage, cruising lanes and elephant puddles. Evidence of the existence of elephants in Sembilang National Park strongly indicates that future actions, participation and attention of all stakeholders are needed to the conservation efforts of the biggest Sumatran mammals in Sembilang National Park

A research to monitor the presence of Sumatran elephant between two ecosystem in Sembilang National Park (TNSTNS) and palm palm oilplantation has been conducted on March until June 2019 at Semenanjung Banyuasin Semenanjung, South Sumatra. This research aimed to verify the presence of Sumatran elephantpopulation and to estimate the number of elephant individuals in the area. The methods used weredirect observation during the day and indirect monitoring through installation of Camera Traps for 1 month. In addition, secondary data was collected in the form of data archives from the palm oil plantation records and interviews with affected plantation workers. From direct observation, Wedirect encountered one elephant individual and fifteen signs of elephant activities, such as sounds, footprints, and feces. From camera trap photos, we identified and verified onepopulation of Sumatran Elephants which consisted of at least twenty-two individuals with composition as follows: eight adult females, two young females, three infant females, and nine males. The ecotone area between TNS and palm palm oil plantation should be designated as a new habitat patchof Sumatran elephant that needs to be managed appropriately in order to maintain the designation of the area as aÂ conservation area.

Sumatran Elephants (Elephas maximus sumatranus) is one of the endemic Sumatran fauna that is protected by Indonesia Law. The Remnant Forest of Acacia District Penyabungan in the landscape of Padang Sugihan is one of the elephantâ€™s habitats in South Sumatra. Habitat degradation and fragmentation, poaching and conflicts become the major threats for the elephant population. Genetic study is one of the efforts to establish a conservation policy. It is necessary to test the quantitative and qualitative of DNA, at the extractions stage from fecal samples, in order to get the standard results on DNA concentration which will be analyzed later. The method used is through direct observation as the initial survey to determine the sampling location. Fecal samples were preserved in absolute ethanol at -20Â°C.Â The extraction process was carried out using the Quick-DNATM Fecal/Soil Microbe Miniprep Kit. Samples were tested quantitatively using a Nanodrop Thermo Scientific, with the expectation that the concentration results were considered to be 1.6-1.8 and continued with the qualitative test of DNA through electrophoresis gel agarose and UV Transilluminator. Of the 20 samples, only 12 samples showed positive results (there were DNA bands). The results of this quantitative and qualitative test could be used to determine a viable sample to be used as a product in the genetic analysis stage of Sumatran Elephants in the Remnant Forest of Acacia South Sumatra.

Remnant forests of PT. Suryabumi Agrolanggeng and surrounding traditional rubber plantations need to be managed as habitat for some wildlife as well as an important region for the company's activities. Tarsier which is one of the protected wildlife inhabit the area has the potential to become a "flagship species" in the frame of environmental management efforts of the Company. This study was aimed to estimate the ab-undance and habitat of tarsiers in such area. The study sites consist of forested area of PT. Suryabumi Agro-langgeng forests (study site-1) and the traditional rubber plantations managed by local people (study site-2). The estimated abundance of tarsier in both sites were respectively 0,25 ind/ha and 0,08 ind/ha. Plant species found are 18 species of 14 families and 23 species of 15 families. Potential number of insects as tarsier prey are 20 species of 14 families. SWOT analysis approach to internal and external factors showing High Conservation Values (HCV) of the forested area of PT. Suryabumi Agrolanggeng (study site-1) and could lead the determina-tion of the status of such area as a conservation area.
