Macacajascicularis is one ofthe primates inhabiting Alas Purwo National Park. Being taken advantage for tourist attraction, located in an area ofintensive tourism, Mjascicularis requires special attention especially the one focusing on their population dynamics. There are a number of aspects which are worthy ofthe study in order to figure out the dynamics ofa population that is ever changing i.e. the birth rate, mortality, predation, migration, dispersion, age distribution, sex ratio, and social organization ofa species. The aim ofthis research is to find out the population structure (including age distribution, sex ratio, and density), home range, and the vegetation structure found in three groups of Mjascicularis in Rowobendo Resort i.e. Rowobendo Post, Pura,Giri Salaka, and Triangulasi. Hopefully this research could provide ·information for the planners, the managers of Alas Purwo National Park, .and the researchers from other institutes attempting to arrange and make use ofthe animal without causing any damage tothe nature conservation in this region. Concentration Count Method is implemented to find out the population structure ofthe three groups ofMjascicularis. It is counted twice a day during 12 days ofobservation. Another method implemented is Line Transect Method to estimate the whole range ofM.jascicu/aris population living in Rowobendo Resort by using six lines ofobservation spreading around the area. It is assumed to be able to represent the whole resort in this region. The home range ofMjascicularis can be detected by following the daily movement of one or more individuals chosen as the,samples from morning.to afternoon. Each group is observed in four sequential days in October-November 2002 by using Magellanz Blazer Global Positioning System (GPS) to record the data. Point-Centered Quarter Method is used to obtain the data ofvegetation structure at the level ofpole and tree (more than 10 cm dbh) and Quadrat Method is used to obtain the data .ofground cover vegetation structure. The sampling process for vegetation data is done by using random preliminary systematic system. The finding ofthe research shows·that group ofMjascicularis inhabiting Pura Giri Salaka has the highest population consisting of 49 macaques with the density of 2,07 ind/Ha; followed by Triangulasi troop consisting of 38 macaques with density of 1,82 ind/Ha, and the lowest is of Rowobendo Post troop consistingof30 macaques with the density of1,08 ind/Ha. The home range of Mjascicularis in three areas ofobservation i.e. Rowobendo Post, Triangulasi, andPura Giri Salaka are 27,71 Ha, 23,64 Ha, and 20,84 Ha with average length ofmovement of1280 ~ 1089 ~ and 997 m. The largest variety ofthe vegetation is found in Triangulasi consisting of48 kinds ofspecies from 40 families, followed by that ofRowobendo Post consisting of27 kinds from 14 families, and the least is that ofPura Giri Salaka consisting of23 kinds from ·10 families. The vegetation found in Rowobendo Resort is made use as the source offood, playground, place to rest, shelter and cover, as'well as for a sleep. The vegetation mostly used for food is ofFicus sp, Tectona grandi..~, Cassia siamea, Eugenia javanica, Hibiscus tiliaceus, Samanea saman, and De/onix regia.
