Abstract

The Ketambe Research Station is an important habitat for the Sumatran orangutan (Pongo abelli), which experiences many disturbances from the community, such as forest encroachment and illegal logging. This condition has caused 7% habitat destruction. The impact of habitat destruction has led to a decline in the orangutan population. This study aims to determine the population of Sumatran orangutans at the Ketambe research station. The study took place at the Ketambe research station, Mount Leuser National Park (TNGL) Aceh Tenggara, for three months from April to June 2021, using the purposive sampling method, and the orangutan population data collection technique using the line transect method as many as 9 (nine) transects. , placed: riverbanks, plains, ridges, and mountain peaks. Data analysis for this study used the formula d = N / 2 w L: Estimating nest density (d), number of nests (N), length of observation path (L), width of observation path (w), according to (Van Schaik, 1995) is Estimated density of each nest/species found. The observation paths are 1 km long each and the left and right are 25 m wide, the Sumatran orangutan population density found is 0.7291 Individuals/Km², with a total of 104 nests. From the total area of ​​observation 45 ha (450,000m²). Based on the results of the study, the most preferred type of meranti (hopea cernua) was the Sumatran orangutan for making nests at the ketambe research station. The most distribution of nests based on diameter size is 21-40 cm, based on nest height is at a height of 10-20 m, based on nest position is in position 1, based on nest class is in class C, and based on tree height is in class 15-25 m. Based on the results obtained, the types of trees that orangutans prefer for nesting can be used as a type of planting activity, orangutan habitat restoration.

Abstract

The orangutan, a vital component of the rainforest ecosystem, is increasingly threatened by habitat loss and fragmentation. Identifying orangutan nests and feeding trees is an important elements in understanding the habitat's capacity to sustain this species. Using the transect method, this study was conducted on 40 grids out of a total of 623 grids in the Tripa area that are still covered by forest. This study aimed to record the presence of orangutan nests and identify various plant species that serve as food sources for orangutans. The result revealed the discovery of orangutan nests in 7 locations, most of which were categorized as type C (old) and type D (very old). A total of 13 potential orangutan food plant species were found in the Rawa Tripa forest area, consisting of the families Moraceae, Euphorbiaceae, Annonaceae, Myrtaceae, Myristicaceae, Apocynaceae, Piperaceae, Dipterocarpaceae, Urticaceae, and Pandanaceae. This suggest that these areas may have supported a significant orangutan population in the past, but their current activity appears to be declining. The findings underscore the need for conservation efforts, as the continued survival of orangutans is crucial not only for their species but also for the ecological health of the forests they inhabit.

Abstract

The Jantho STIK educational forest is an important habitat for the kedih primate species (Presbytis thomasi), the gray langur (Christatus auratus), and the long-tailed macaque (Macaca fascicularis). The destruction of these primate habitats through forest encroachment is also carried out by the community around the educational forest. The conservation status for these three species is listed as vulnerable in the IUCN and Appendix II in CITES. They are protected animals. Habitat disturbance in the form of forest encroachment is often carried out by the community. This encroachment results in a decline in the quality of primate habitats, due to the loss of food sources and the loss of sleeping trees. In order for the protection of primate species and habitats to take place properly, and the economic value of the community can increase with the presence of primates, as well as to suppress the rate of forest encroachment, it can be done by building ecological barriers in the primate habitat. This ecological barrier is basically made to improve the habitat of wildlife that is experiencing fragmentation. In addition, it is to keep wildlife in their home range, and not to leave their habitat into community agricultural areas. The community service was conducted on August 22-24, 2025, at the STIK education forest in Boeng Jantho village. Community service included socialization of ecological barriers, planting vegetation on ecological barriers, mentoring, evaluation and monitoring. The ecological barrier was made in an area of ​​one hectare and planted with types of vegetation that are not favored by primates (pine, sugar palm and candlenut). The community's enthusiasm was quite high to participate in the socialization and planting. The vegetation developed on ecological barriers can control animals from leaving their natural habitat, so that hunting can be suppressed and forest encroachment can decrease.

Abstract

The availability of lime or lemon in Aceh is sufficient, even exceeding household needs, so it can be processed into other innovations for domestic use, such as dishwashing soap. Lime contains various beneficial chemical compounds, including: citric acid, which functions as a chelating agent that helps break down dirt and grease; and limonene, a natural compound that acts as a degreasing agent while also providing a fresh aroma.The innovation of producing organic dishwashing soap is highly needed by the community. Economically, the benefits of this dishwashing soap can help reduce household expenses, allowing families to reallocate their budget to other needs, such as fulfilling nutritional requirements. Environmentally, this eco-friendly dishwashing soap can help preserve water quality by reducing household waste pollution. For lime and suji leaf farmers, this innovation can increase the sales of their agricultural products, thereby boosting cross-sectoral economic growth at the grassroots level.
