Abstract


Capung merupakan komponen keanekaragaman hayati yang memiliki peran sebagai bioindikator pencemaran lingkungan. Penelitian ini bertujuan untuk mengidentifikasi spesies dan menganalisis keanekaragaman capung di Sungai Kali Desa Kali, Kabupaten Minahasa, Sulawesi Utara. Pengambilan sampel dilakukan dengan mengunakan metode purposive random sampiling. Penelitian ini dilaksanakan pada tepi sungai kali  yang terletak pada tiga  tipe habitat yaitu di tepi sungai hutan sekunder, tepi sungai perkebunan dan tepi sungai permukiman. Masing-masing habitat dibuat tiga garis transek dengan panjang 300 Meter. Komposisi capung yang diperoleh terdiri dari 6 famili, 19 spesies dan 1.785 individu. Famili yang paling banyak ditemukan jumlah spesiesnya adalah Libellulidae. Spesies yang memiliki kelimpahan yang tertinggi Neurothemis ramburii dan Ortetrum pruinosum. Indeks kekayaan spesies di Sungai Desa Kali di kategorikan rendah, indeks keanekargaman di kategorikan sedang dan indeks kemerataan spesies tergolong dalam ketegori tinggi

Dragonfly is a biodiversity component that has a role as a bioindicator of environmental pollution. This study aims to identify species and analyze the diversity of dragonflies in Kali River Kali Village, Minahasa Regency, North Sulawesi. Sampling is done by using purposive random sampling method. This research was carried out on the river banks which are located in three habitat types, namely on the banks of secondary forest rivers, plantation banks, and residential riverbanks. Three transect lines were made on each habitat with a length of 300 meters. The dragonfly composition obtained consisted of 6 families, 19 species and 1,785 individuals. Most of the species are from family Libellulidae. Species with the highest abundance are Neurothemis ramburii and Ortetrum pruinosum. The species richness index in the Kali River River was categorized as low, the economic index was categorized as moderate, and the species evenness index was classified as high
