The research method used the line transect method by collecting data on the number of individuals, the number of groups, the sex ratio, and the age structure. The research was conducted at four observation locations with a duration of three months, observations were made from 06.00 WIT to 17.00 WIT, and four repetitions were carried out on each observation path, the results obtained were a total of 16 Javan surili individuals found which were divided into one group, and the estimated population density is 0.06 individuals/hectare. The sex composition of male and female Javan surili in the TSI Bogor forest area is 1:6 where there are more female Javan surili than male Javan surili, and for the age structure of the Javan surili the most are in the adult age class with a percentage of 43.75%, juvenile 31.25%, and the percentage of infent by 25%.
