Combining analytical hierarchy process (AHP) and geographical information system (GIS) for mapping habitat threat of mentilin (Cephalopachus bancanus)

Taman Hutan Raya (Tahura) Gunung Menumbing (TGM) is a protected area located in Muntok, West Bangka that has unique plants and animals that represent the low-land forest ecosystems of Bangka-Belitung Island. However, the biodiversity is threatened due to massive destructive activities from illegal tin mining, logging, hunting, and agriculture practices. This study aims to map the habitat threat of the western tarsier (Cephalopachus bancanus), locally called mentilin, which is one of the most threatened animals in Tahura Gunung Menumbing. To achieve the study objective, this study used the combination of Analytical Hierarchy Process (AHP) and Geographical Information Systems (GIS). The AHP analysis was carried out to determine the weight and score of selected parameters that affect to habitat suitability of mentilin and its potential threats. The data were collected from in-depth interviews, focus group discussions, and questionnaires sent by an electronic mail to experts. In total, there were fourteen experts representing NGO in Bangka Island, ex-poacher, researchers, and governments contributed to the research. The results showed that 62 of the area in the TGM was prone to mentilin habitat. This result indicated that mentilin in the TGM is facing serious threats and conservation actions are urgently needed. © 2021 IOP Conference Series: Earth and Environmental Science
