Abstract

The forest area on the slopes of Mount Merapi, located in the northern part of Yogyakarta, has a lot of flora and fauna. One of the fauna that lives in the area is a long-tailed monkey (Macaca fascicularis Raffles 1821). Long-tailed monkeys eat lots of fruit and are grouped into frugivorous animals. However, long-tailed monkeys, such as leaves and flowers, will have more abundant food in their habitat. Therefore, this study analyzed long-tailed monkey feed to see the percentage of long-tailed monkeys who chose feed. In addition, phytochemical content analysis was conducted as supplementary data to determine the feeding preferences of long-tailed monkeys. The data obtained were analyzed descriptively. The results showed that the plant species selected by the long-tailed monkeys in the Tlogo Muncar and Tlogo Nirmolo areas were Cinchona pubescens Vahl, Leucaena leucocephala (Lam.) de Wit, Melastoma polyanthum Burm. f, Carex flaca and Sp 1. The plant parts that long-tailed monkeys ate were almost entirely leaves. Phytochemical tests on samples consisted of steroid, flavonoid, phenol, saponin, and triterpenoid tests.
