Abstract
Long-tailed macaque (Macaca fascicularis) are one of the primates that are quite widespread in Indonesia, one of its in the area of Teluk Akar Bergantung city forest on Ketapang, West Kalimantan. This study aims to obtain data on the number of groups, number of individuals, population density, and structure of long-tailed macaque populations in the region using the line transects method and concentration count method. At the 95% confidence interval, the number of individuals ranged from -1,38 ind/ha to 30,20 ind/ha and the number of groups ranged from 0,72 groups/ha to 2,70 groups/ha. Population individual densities ranged from -0,39 ind/ha to 8,83 ind/ha and population group densities ranged from 0,21 groups/ha to 0,79 groups/ha. Structure of long-tailed macaque in the area of Teluk Akar Bergantung city forest on Ketapang, consists of 7,67 individuals of adult male, 9 individuals of adult female, 23,67 individuals of adolescent and 1,33 individual of children. Factors that affect the stability of long-tailed macaque populations include environmental conditions, types of feed, movement, interaction with other animals and the presence of predators.Keywords: Long-tailed macaque, population density, population structure, Teluk Akar Bergantung city forest.

Summary
Monyet ekor panjang hanya memakan pakan alam seperti dedaunan dari beberapa pohon yang tidak berbuah. Kelompok yang menjelajah pada lokasi yang jarang didatangi pengunjung hanya mendapatkan pakan dari alam, namun tumbuhan pakan alami tersebut memiliki musim berbuah sehingga tidak setiap waktu dapat menyediakan pakan bagi monyet ekor panjang di lokasi penelitian. Kelompok ini tidak menetap lama di lokasi tersebut, mereka akan kembali pada lokasi yang lebih sering dikunjungi manusia untuk mendapatkan makanan, akibatnya monyet ekor panjang di kawasan hutan kota ini lebih banyak terdapat pada bagian pintu masuk hutan kota. Pada pagi dan siang hari kelompok ini dapat dijumpai berkumpul di sekitaran Resort untuk mencari makan, baik itu pakan alami di daerah hutan depan resort maupun pakan non-alami yang didapatkan dari pengunjung atau tempat sampah yang tersedia. Jumlah individu dan kelompok untuk setiap jalur dapat dilihat pada Gambar 2
