UJI TURNITIN BEKANTAN (Nasalis larvatus) HABITAT SUITABILITY IN TABUNIO WATERSHED IN SOUTH KALIMANTAN

Abstract

The transfer of forest land to non-forests is increasingly massively carried out by humans, including in riparian forest areas (left-right forests of rivers). The study aimed to identify determining factors that affect the suitability of bekantan (Nasalis larvatus Wurmb, 1781) in the riparian habitat of the Tabunio watershed in South Kalimantan through spatial modeling. Habitat suitability is analyzed using Sentinel-2 imagery and cellular automata and integrated with geographic information systems. The encounter with bekantan in Tabunio watershed as many as 443 bekantan individuals spread across 43 meeting points and consists of five main groups of bekantan with the number of group members for each of the main groups ranging from 20 - 68 individuals, With the average number of individuals grouped is 10.3 individuals The total area suitable for settlement habitat in the Tabunio watershed is 2.1113,84 hectares, or 3.38% of the entire Tabunio watershed area which totals 62.516,24 hectares. The model of the results of this study explains that the distribution of bekantan habitat suitability is influenced by the disturbance factor.
