Javan slow loris (Nycticebus javanicus) is a primate endemic to the island of Java which plays a role in maintaining the balance of the ecosystem. Illegal trade and habitat conversion have caused Javan slow loris population to continue to decline. Masigit Kareumbi Hunting Reserve (TBMK) is one of the locations for reintroduction of Javan slow loris from 2018-2019, but until now there has been no monitoring of the distribution of Javan slow loris after release. Information regarding the distribution is needed in further action to realize Javan slow loris. This study aims to predict patterns and identify variables that influence the distribution of Javan slow loris in TBMK. Data on encounters with Javan slow lorises were collected through observation and interviews with management officers, local residents and IAR Indonesia. Observations were made using a purposive method on 4 lanes around the Kampung Cimulu enclave. Distribution prediction was carried out using topographical variables (elevation and slope), ecology (land cover type and NDWI), climatology (precipitation and surface temperature) and anthropogenic (distance from roads and distance from settlements). Modeling is done using Maxent with a stepwise modeling system. Obtained data on the location of slow lorises around the enclave and the edge of the TBMK area. Based on direct observation, three lorises were found on red calliandra trees (Calliandra calothyrsus) and slow loris bite marks on tepus (Etlingera coccinea). The best combination for estimating the distribution of the Javan slow loris consists of 5 variables, namely distance from settlements, rainfall, slope, land cover and NDWI. The variable with the highest level of importance and contribution is the distance from the settlement because the Javan slow loris has the ability to adapt to the availability of resources. Based on the modeling carried out, a distribution area of 0,5% of the total TBMK area was obtained with a distribution pattern clustered around Cimulu. This can pose a threat of conflict with humans and indicates a low level of dispersal. TBMK has the potential to become a special conservation area for the Javan slow loris, but must be accompanied by further efforts so that the threat can be minimized.
