Kawasan Hutan Mangrove di Kelurahan Mamburungan Kota Tarakan, terdapat berbagai macam fauna yang hidup didalamnya, salah satunya adalah kepiting. Masyarakat setempat belum banyak mengetahui jenis kepiting yang ada dan belum dijadikan sebagai potensi pembelajaran biologi. Penelitian ini bertujuan untuk menganalisis identifikasi keanekaragaman jenis kepiting di Kawasan Hutan Mangrove Kelurahan Mamburungan Kota Tarakan serta Potensi Pemanfaatanya pada Pembelajaran Biologi. Penelitian yang digunakan adalah penelitian deskriptif eksploratif dengan pendekatan kuantitatif, teknik yang digunakan adalah teknik purposive sampling (sampel bertujuan). Pada penelitian ini ditemukan delapan spesies kepiting yaitu Metaplax dentipes, Perisesarma darwinensis, Paraleptuca crassipes, Tubuca coartata, Uca annulipes, Uca rosea, Uca tetragonon dan Uca vocans. Indeks keanekaragaman jenis kepiting di Kawasan Hutan Mangrove Kelurahan Mamburungan Kota Tarakan termasuk dalam kategori sedang yaitu H’ = 1,62. Potensi pemanfaatan hasil penelitian pada pembelajaran biologi terdapat pada materi animalia invertebrata kelas VII SMP dengan kompetensi dasar (KD) 3.2 Mengklasifikasikan makhluk hidup dan benda berdasarkan karakteristik yang diamati dan (KD) 4.2 Menyajikan hasil pengklasifikasian makhluk hidup dan benda di lingkungan sekitar berdasarkan karakteristik yang diamati.

In Mangrove Forest Area of Mamburungan Sub-district of Tarakan City, there found various kinds of fauna, one of which is crabs. The local community does not know exactly about the species of crabs that exist and has not yet been used as a potential for learning biology. This research aimed to analyze the identification of crab species diversity in Mangrove Forest Area of Mamburungan Sub-district of Tarakan City and the potential utilization in Biology learning. This research employed descriptive exploratory research with a quantitative approach in which the samples were chosen using a purposive sampling technique. In this research, eight species of crab were found, namely Metaplax dentipes, Perisesarmsa darwinrnsis, Paraleptuca crassipes, Tubuca coartata, Uca annulipes, Uca rosea, Uca tetragonon, and Uca vocans. The index of the diversity of crab species in Mangrove Forest Area of Mamburungan Sub-district of Tarakan City was classified in medium category, namely H' 1.62. The potential for utilizing this research results in Biology learning was found in the learning material of invertebrate animals for the seventh-grade students of Junior High school under the basic competence (KD) 3.2 Classifying the living creatures and objects based on observed characteristics, and KD 4.2 Presenting the results of classifying the living creatures and objects in the surrounding environment based on observed characteristics.
