Abstract
Indonesia merupakan salah satu negara dengan tingkat keanekaragaman hayati tinggi, termasuk keragaman jenis insekta salah satunya adalah ordo Odonata. Secara ekologis capung memiliki peranan penting dalam menjaga keseimbangan ekosistem, salah satunya sebagai predator. Secara umum, capung ordo odonata digolongkan menjadi dua subordo yaitu Anisoptera (capung biasa) dan Zygoptera (capung jarum). Pada kedua jenis subordo ini memiliki perbedaan yang cukup mencolok dalam bentuk mata, sayap, bentuk tubuh dan perilaku terbang. Penelitian ini dilakukan di tiga tipe habitat yang berbeda yakni kebun, hutan sekunder dan sawah pada kawasan agroekosistem di Desa Jatiarjo, Prigen, Jawa Timur. Tujuan dari penelitian ini adalah untuk mengetahui komposisi dan tingkat keanekaragaman capung pada tipe habitat berbeda di kawasan agroekosistem Desa Jatiarjo, Prigen, Jawa Timur. Metode pengamatan keanekaragaman capung pada penelitian ini menggunakan metode VES (Visual Encounter Survey) yang dimodifikasi dengan metode jelajah yang menyesuaikan dengan kondisi lapangan. Metode VES dikombinasi dengan bantuan sweep net dan kamera untuk dokumentasi dalam membantu identifikasi lebih detail. Berdasarkan hasil penelitian yang telah dilakukan, diperoleh komposisi spesies dan kelimpahan capung pada kawasan agroekosistem Desa Jatiarjo, Prigen sebanyak 16 spesies yang terdiri dari 2 subordo, 7 famili yang berbeda dengan jumlah total individu sebanyak 921 individu. Berdasarkan tipe habitat ditemukan bahwa kelimpahan individu capung tertinggi terdapat pada habitat hutan (7 famili, 14 spesies, dan 336 individu), diikuti oleh habitat sawah (7 famili, 13 spesies, 305 individu), dan habitat kebun sebanyak (1 famili, 7 spesies, dan 280 individu). Spesies Pantala flavescens dan Orthetrum sabina paling mendominasi di ketiga tipe habitat, serta ditemukan capung endemik Jawa yaitu Heliocypha fenestrata. Nilai indeks keanekaragaman kawasan agroekosistem Desa Jatiarjo, Prigen termasuk kategori sedang, di mana nilai indeks keanekaragaman tertinggi pada habitat hutan (H’ = 2,32), diikuti oleh sawah (H’ = 2,08), dan terendah di habitat kebun (H’ = 1,47). Nilai indeks kemerataan pada ketiga habitat termasuk kategori kemerataan tinggi, di mana nilai kemerataan tertinggi di habitat hutan (E = 0,88), diikuti oleh habitat sawah (E = 0,81) dan yang terendah ditemukan di habitat kebun (E = 0,75). Sementara itu, nilai dominansi pada ketiga habitat termasuk kategori rendah, di mana habitat hutan dengan nilai indeks dominansi terendah atau stabil (D = 0,12), dibanding habitat kebun (D = 0,29), dan habitat sawah (D = 0,18).

Indonesia is a country with a high level of biodiversity, including a variety of insect species, one of them is of the Odonata order. Ecologically, dragonflies have an important role in maintaining the balance of the ecosystem, which is as a predator. In general, dragonflies of the Odonata order are classified into two suborders, namely Anisoptera (ordinary dragonflies) and Zygoptera (damselflies). The two types of suborder have quite striking differences in the shape of the eyes, wings, body shape and flight behavior. This research is conducted in three different types of habitat, which are gardens, forests and rice fields in the agro-ecosystem area in Jatiarjo village, Prigen, East Java. The purpose of this study is to determine the composition and level of diversity of dragonflies in different habitat types in the agroecosystem area of Jatiarjo Village, Prigen, East Java. The method of observing the diversity of dragonflies in this study used the VES (Visual Encounter Survey) method which was modified with the field by field method (metode jelajah) according to field conditions. The VES method used sweep nets and cameras for documentation to help identify in more detail. During the course of the study, 921 individuals were encountered and identified as 16 species from 2 suborders and 7 families. The forests yielded a highest abundance of 336 individuals from 7 families and 14 species, followed by the ricefields with 305 individuals from 7 families and 13 species, and the lowest abundance being the gardens with 280 individuals from 1 family and 7 species. Pantala flavescens and Orthetrum sabina are two of the most dominating species in all three types of habitats. A species of endemic damselfly, Heliocypha fenestrata was also encountered during the field study. In terms of diversity, the agro-ecosystem area of Jatiarjo village, Prigen was found to be of medium category according to diversity index, with the forests habitat scoring the highest (H’ = 2,32), followed by the rice fields habitat (H’ = 2,08), the lowest being the gardens (H’ = 1,47). In terms of evenness, all three types of habitat scored high, with the highest being the forests habitat (E – 0,88), followed by the ricefields (E = 0,81), and the last being the gardens (E = 0,75). Lastly, all three habitats were of low dominance category according to the dominance index, with the lowest and most stabile being the forests (D = 0,12), compared to the gardens (D = 0,29) and the ricefields (D = 0,18).
