Penelitian ini bertujuan; (1) melakukan analisis struktur lanskap pada area budidaya tanaman hortikultura berdasarkan SIG di pulau Tarakan; dan (2) mengetahui hubungan karakteristik lanskap dengan keanekaragaman capung (Ordo: Odonata) di pulau Tarakan. Pengambilan contoh capung pada 4 lokasi yakni Tarakan Timur, Tarakan Utara, Tarakan Barat, dan Tarakan Tengah. Selain itu, dilakukan analisi lanskap, pengambilan data suhu, kelembaban, intensitas cahaya, dan Ph air. Indeks keanekaragaman lanskap(H), indeks kekayaan jenis (R), indeks keanekaragaman Shannon (H), indeks kemerataan(E), regresi, diagram venn dan analisis deskriptif. Hasil penelitian menunjukkan struktur lanskap terdiri dari beberapa jenis tapak yakni tapak budidaya tanaman sayuran, tanaman buah-buahan, rawa/kolam, pemukiman, hutan sekunder. Indeks keanekaragaman lanskap tertinggi di Tarakan Barat. Komposisi spesies capung di Pulau Tarakan terdiri dari 3 famili, 10 genus, 17 spesies. Indeks kekayaan spesies tertinggi di Tarakan Timur, sedangkan indeks keanekaragaman dan indeks kemerataan tertinggi di Tarakan Barat. Terdapat hubungan antara keanekaragaman lanskap dan keanekaragman capung, misalnya tanaman sayuran menyebabkan area lebih terbuka dan disukai oleh capung.

The purpose of this research were to (1) analyze the landscape structure of the horticultural cultivation area based on GIS on the island of Tarakan and (2) find out the relationship between the characteristics of the landscape and the diversity of dragonflies (Order : Odonata) on the island of Tarakan. Dragonfly samples were taken from 4 locations, namely East Tarakan North Tarakan, West Tarakan, and Central Tarakan. In addition, analyses were performed on landscape, temperature, humidity, light intensity, and water Ph, landscape diversity index (H), species richness index (R), Shannon diversity (H), evenness index (E), regression, venn diagram and descriptive analysis. The result showed that the landscape structure consisted of several types of sites, namely the cultivation of vegetables, fruit trees, swamps/ponds, settlements, and secondary forest. The highest index of landscape diversity was in West Tarakan. The composition of dragonfly species on Tarakan Island consisted of 3 families, 10 genera, and 17 species. The highest species richness index was in East Tarakan, while the highest diversity index and evenness index were in West Tarakan. There was a relationship between landscape diversity and dragonfly diversity, for example vegetables crops made the area more open and favored by dragonflies.
