Abstract

The long-tailed mcaque (Macaca fascicularis) has a fairly wide population distribution in Indonesia. According to IUCN data, the population of long-tailed mcaque is decreasing every year, the cause is a decrease in habitat quality. One of the habitats of long-tailed mcaque which is currently under pressure due to conversion is located in a buffer village around the Orang Kayo Hitam Forest Park (Tahura OKH). This study aims to analyze the composition and age class of long-tailed monkeys. Observation methods were used to observe long-tailed mcaque based on morphological characteristics such as coat color and body size. Based on the results of the study, the composition of long-tailed mcaque was divided into two groups, the residential group (KP) and the river border group (KS). The number in KP is 8 individuals with an age class of 5 adults, 3 immature while the number in KS is 27 individuals with an age class of 18 adults, 4 immature, 3 juvenile, 1 infants. This condition illustrates that the river border habitat is better than the residential habitat. In addition, adults and adolescents are more numerous, indicating individuals who have a function for reproduction and continue reproduction. This breeding rate is the potential for regeneration of long-tailed mcaque and the potential for the regeneration process of peat ecosystems through the role of long-tailed monkeys as pollinators for seed dispersal.

Abstract

Peatlands are vulnerable to fire, causing ecological damage that threatens biodiversity, one of which is amphibians. The nature of amphibians which are sensitive to environmental changes can be used as a bioindicator of the quality of a disturbed environment, including in buffer villages around conservation areas. This research aims to analyze the diversity of amphibians and their relationship with temperature and air humidity. The method used is Visual Encounter Survey (VES) in two types of habitats, namely oil palm plantations and swamps. Data analysis used the Shannon-Wiener species diversity index, the Pielou species evenness index, and the Pearson correlation test. The research results found 6 species of amphibians, namely Hylarana erythraea, Hylarana nicobariensis, Fejervarya limnocharis, Fejervarya cancrivora, Duttaphrynus melanustictus, and Hylarana baramica. The diversity index (H') in oil palm plantations and swamps is H'=1.46 and H'=1.10 in the medium category. This shows that ecologically, the conditions of the habitat types of oil palm plantations and swamps in the buffer villages around the Orang Kayo Hitam Forest Park after land burning can support amphibian life. Key words: Amphibians, conservation area, diversity, tropical peatland.
