ABSTRAK
Populasi monyet ekor panjang yang tersebar luas di Asia Tenggara masuk dalam daftar International Union for Conservation of Nature (IUCN) yang telah berubah menjadi Vulnerable pada tahun 2022, yang menunjukkan peningkatan risiko kepunahan di alam liar. Ancaman terhadap populasi monyet ekor panjang semakin kompleks dengan adanya risiko serangan parasit. seperti infeksi protozoa gastrointestinal yang dapat menular melalui tertelannya makanan atau minuman yang telah terkontaminasi ookista. Penelitian ini bertujuan untuk mendapatkan informasi mengenai ragam jenis protozoa gastrointestinal dan menghitung jumlah prevalensi pada monyet ekor panjang (Macaca fascicularis) di kawasan wisata ekosistem manggrove Kuala Langsa. Sampel yang digunakan berjumlah 5 dan merupakan sampel feses segar yang diambil setelah monyet ekor panjang (Macaca fascicularis) melakukan defekasi yang kemudian di periksa menggunakan metode sentrifus dan sedimentasi formol-eter. Hasil penelitian ini di analisis secara deskriptif. Hasil penelitian menunjukkan bahwa pada metode sentrifus terdapat 3 sampel positif Balantidium sp. dan pada metode sedimentasi formol-eter terdapat 1 sampel positif ookista Eimeria sp. dari 5 sampel feses monyet ekor panjang (Macaca fascicularis) yang di
periksa 4 di antaranya terinfestasi protozoa gastrointestinal yaitu Ookista Eimeria sp. dan Balantidium sp..

Kata Kunci : Kuala Langsa, Macaca fascicularis, Ookista Eimeria sp., Protozoa gastrointestinal.

ABSTRACT The widespread population of long-tailed macaques in Southeast Asia has been listed by the International Union for Conservation of Nature (IUCN) as Vulnerable since 2022, indicating an increased risk of extinction in the wild. Threats to the long-tailed macaque population have become increasingly complex due to the risk of parasitic infections, such as gastrointestinal protozoan infections that can be transmitted through the ingestion of food or water contaminated with oocysts. This study aims to obtain information on the diversity of gastrointestinal protozoa and calculate their prevalence in long-tailed macaques (Macaca fascicularis) in the mangrove ecosystem tourist area of Kuala Langsa. Five samples were used, consisting of fresh feces collected after long-tailed macaques (Macaca fascicularis) defecated, which were then examined using centrifugal and formalin-ether sedimentation methods. The results of this study were analyzed descriptively. The results showed that in the centrifugation method, 3 samples were positive for Balantidium sp., and in the formalin-ether sedimentation method, 1 sample was positive for Eimeria sp. oocysts. out of the 5 feces samples from long-tailed macaques (Macaca fascicularis) examined, 4 were infected with gastrointestinal protozoa, namely Eimeria sp. oocysts and Balantidium sp..
