Abstract

Population of brown plant hopper (Nilaparvata lugens Stal) is one of the major rice pest that is threatening rice production in Indramayu. Integrated pest management is needed to control the population of brown plant hopper (BPH). To construct effective strategy of Integrated Pest Management, a survey to obtain information about the population of BPH and the diversity of its natural enemies predator and parasitoid is required. The result of the survey showed that fluctuation of BPH population was evidence. BPH occurs from the 1st week of observation and the population was rising until the 5th week of observation and hence the population declined until the 12th week of observation. This population decline was caused by BPH’s live cycle followed the growth phase of rice plant. Correlation between climate factors and fluctuation of BPH population was not significant. Based on Shanon-Wiener diversity index analysis, the diversity of natural predators of BPH was medium with the value of H’ of 1,83 due to  uniform field condition

Abstract

Pulau Nusakambangan memiliki habitat yang cukup baik dan catatan keanekaragaman capung yang cukup banyak ini menjadikan Pulau Nusakambangan menjadi menarik untuk diteliti lebih lanjut terutama kaitannya dengan tipe-tipe habitat yang ada di Pulau Nusakambangan. Penelitian ini bertujuan untuk mengetahui keanekaragaman jenis capung di Pulau Nusakambangan. Penelitian dilaksanakan pada Bulan Agustus, September dan Desember tahun 2020 di Pulau Nusakambangan, Kabupaten Cilacap, Jawa Tengah. Penelitian ini dilaksanakan di 10 lokasi pengamatan. Pengambilan data dilakukan dengan metode Visual Encounter Survey. Analisis data habitat dilakukan dengan metode deskriptif kualitatif, analisis keanekaragaman jenis capung dihitung menggunakan Indeks Keanekaragaman Shannon-Wienner. Berdasarkan penelitian yang telah dilakukan di Pulau Nusakambangan teramati sekitar 695 individu dengan jumlah spesies sebanyak 45 jenis capung yang termasuk dalam 10 family. Nilai indeks keanekaragaman di Pulau Nusakambangan secara total tergolong tinggi dengan nilai 3,05. Kata kunci: Capung, Odonata, Nusakambangan

Abstract

National parks are one of a site to maintain biodiversity from any damage. Tanjung Puting National Park is one of the national parks in Indonesia with a wide variety of biodiversity, namely butterflies. The aims of this study were to determine the diversity of butterfly species in 5 sub-ecosystems in Tanjung Puting National Park. The five sub-ecosystems are Camp Ambung, post-burn forest, heath forest, lowland forest and swamp forest. In this study, the butterflies were caught through the hunting method by using insect nets and the trapping method by installing food traps. This study was conducted from February to March 2022 for twice times a day from 8 to 12 in the morning and 1 to 5 in the afternoon. The results showed that butterflies collected were 121 species of butterflies from 6 families in Pondok Ambung, Tanjung Puting National Park. In detail, there were 88 species in Camp Ambung, 19 species in the post-burn forest, 14 species in the heath forest, 65 species in the lowland forest, and 38 species in the swamp forest. The diversity index from highest to lowest was Camp Ambung (3.71), lowland forest (3.49), swamp forest (3.02), post-burn forest (2.61), and heath forest (2.36).
