Abstract

This research was motivated by the lack of research on the siamang in hutan Adat Guguk of Merangin Regency, Jambi Province. The purpose of study was to determine and describe the siamang population based on the size of the group, the composition of age and sexual rasio in the forest of Adat Guguk Merangin Regency, Jambi Province. The method used is a concentreated area method with three observation stations and used the Rappid Assesment to record food and rest vegetation of siamang. Data was analyzed descriptively. The result showed that the siamang group found in the study area were 2 groups (5 individuals ) and 1 solitary male. The distribution of age classes in the individual adult phase is 5 individuals the sapling phase was 1 individual and the baby phase werw not found in the siamang group in the hutan Adat Guguk. The seksual ratio value of the siamang group in the adult phase is 1:1, for the solitary male the sexual ratio is 1:0 and ato the juvenile phase could not identyfied the sex of simang because the sexual chaarteristic of had not developed perfectly.

Abstract

This study aims to determine the diversity of ants in Hutan Adat Guguk. Research type applied is descriptive quantitative research. This study was conducted on April 2018, in two stages. The first stages is sampling which is done in the Hutan Adat Guguk by making four plots. The second stage is identification of ants carried out by purposive sampling technique, which is by considering the type of vegetation and altitude. The method used is bait trap, pitfall trap, and hand collecting. Collected samples were analyzed with Shannon-Wiener diversity index (H`), index of richeness (DMg), and evennes index (E). The result showed the ants with 2633 individuals were clasified in to 22 species, consisting of 7 genera and 3 subfamilies. The result of data analysis showed the value of the Shannon-Wiener diversity index (H`) is 2,21 (medium criteria), index of richeness (DMg) is 17,05 (high criteria), and evennes index (E) is 0,41 (stable criteria).
