Abstract


ABSTRAK

Kupu-kupu merupakan serangga yang termasuk dalam ordo Lepidoptera. Serangga tersebut memiliki peranan yang penting dalam suatu ekosistem yaitu mempertahankan keseimbangan ekosistem dan memperkaya keanekaragaman hayati di alam. Penelitian ini bertujuan untuk menganalisis keanekaragaman kupu-kupu di kawasan Bendungan Ulung Peliang, Kecamatan Tamako, Kabupaten Kepulauan Sangihe, Sulawesi Utara. Teknik pengambilan sampel menggunakan metoda transek. Pengambilan sampel dilakukan pada tiga tipe habitat yaitu habitat pinggir bendungan, hutan dan kebun. Pada masing-masing habitat dibuat transek dengan panjang 300m. Pengambilan sampel kupu-kupu dilakukan sepanjang garis transek menggunakan sweepnet. Komposisi kupu-kupu yang diperoleh terdiri dari 5 famili, 30 spesies dan 463 individu. Famili yang paling banyak ditemukan jumlah spesies dan individunya adalah Nymphalidae. Spesies yang memiliki kelimpahan tertinggi adalah Junonia hedonia intermedia dan Eurema tominia. Analisis keanekaragaman didapatkan bahwa indek kekayaan, indek keanekaragaman dan indek kemerataan spesies kupu-kupu tertinggi ditemukan pada habitat kebun, sedangkan kelimpahan spesies tertinggi terdapat pada habitat pinggir bendungan.

ABSTRACT

Butterflies are insects that are included in the order Lepidoptera. Theses insects have an important role in ecosystem that is to maintain the balance of the ecosystem and enrich the biodiversity in nature. This study aims to analyze the diversity of butterflies in the area of Ulung Peliang Dam, Tamako District, Sangihe Islands Regency, North Sulawesi. The sampling technique used the transect method. Sampling has been carried out in three types of habitats namely dam, forest and garden habitat. Each transect has been made with a length of 300m. Butterfly sampling was carried out along the transect line using. The composition of butterflies that habve been obtained consisted of 5 families, 30 species and 463 individuals. The most abundant family with a number of species and individuals is Nymphalidae. Species that have the highest abundance are Junonia hedonia intermedia and Eurema tominia. Diversity analysis found that the highest wealth index, diversity index and evenness species of butterfly species were found in the garden habitat, while the highest species abundance was in the dam edge habitat.

Keywords: Diversity; butterfly; Ulung Peliang Dam; Sangihe Islands.
