Rekrekan merupakan satwa endemik yang dilindungi dengan status rentan. Rekrekan terdapat pada Taman Nasional Gunung Merbabu, di mana kebakaran hutan dan aktivitas masyarakat mengakibatkan terjadinya perubahan kondisi habitat. Perubahan kondisi habitat diduga mengakibatkan pergeseran penggunaan habitat oleh rekrekan. Diperlukan penelitian mengenai preferensi habitat oleh rekrekan guna mengetahui pengelolaan yang tepat untuk menunjang kelestariannya. 

Penelitian dilakukan pada Februari hingga April 2023. Data rekrekan diperoleh dengan menggunakan line transect yang diletakan secara purposive. Data struktur dan komposisi vegetasi diamati dengan nested sampling. Data kepadatan semak, tutupan tajuk dan tumbuhan bawah, jarak dari jalan, jarak dari sumber air, kelerengan, ketinggian, suhu dan kelembaban diamati dengan protocol sampling. Data kehadiran rekrekan beserta kondisi habitat dianalisis secara kualitatif. Analisis seleksi menggunakan chi-square, analisis preferensi menggunakan indeks Neu, similaritas kondisi antar tipe habitat menggunakan indeks disimilaritas Bray-Curtis, serta pengaruh antar variabel menggunakan regresi Generalized Linear Model.

Berdasarkan hasil penelitian, diketahui habitat yang paling disukai rekrekan di Resort Ampel yaitu hutan campuran dengan nilai 1,0. Padang rumput merupakan tipe habitat yang paling disukai oleh rekrekan di Resort Pakis dengan nilai preferensi 1,00. Sementara preferensi habitat rekrekan di Resort Selo berturut-turut sebagaimana berikut, hutan campuran dengan nilai 0,51, belukar dengan nilai 0,45, dan padang rumput dengan nilai 0,04.

The Javan Fuscous Leaf Monkey is one of the protected endemic animals with vulnerable status. It is found in Mount Merbabu National Park, where forest fires and human activities have resulted in changes of the habitat conditions. Changes in habitat conditions are thought to have resulted in a shift of habitat use. Research about habitat preferences is needed to determine appropriate management and support it sustainability.

The research was conducted from February to April 2023. The presence of Javan Fuscous Leaf Monkey was conducted using line transects that were placed purposively. Data on vegetation structure and composition were observed by nested sampling. Data on shrub density, canopy cover and ground cover, distance from roads, distance from water sources, slope, altitude, temperature, and humidity were observed by protocol sampling. Data on the presence of the colobines and habitat conditions were analyzed qualitatively. Habitat selection analysis was conducted using chi-square, preference analysis using the Neu index, similarity between habitat types using the Bray-Curtis dissimilarity index, and influence between variables using the Generalized Linear Model regression test.

By this study, it is known that mixed forest is the most preferred habitat for Javan Fuscous Leaf Monkey in Ampel Resort with the index value is 1,0. Grass field is the most preferred habitat in Pakis Resort with the index value is 1,0. While in Selo Resort, the most preferred habitat is mixed forest with the index value is 0,51, then shrub with the index value is 0,45, and grass field with the index value is 0,04.
