Abstract

Insekta memiliki biodiversitas dengan penyebaran yang luas diseluruh dunia. Sampling dilakukan sekali dalam seminggu selama bulan Oktober 2019. Ditemukan total 717 spesimen Ordo Diptera yang melingkupi dua famili di Sungai Cigambreng. Tiap famili yang diperoleh melingkupi satu jenis yakni Antocha sp. (Famili Tipulidae.) dan Krenopelopia sp. (Chironomidae). Kehadiran jenis chironomid mengindikasikan adanya beban masukan berlebihan (Polutan) ke dalam perairan sungai Cigambreng. Secara umum, kelimpahan tertinggi diperoleh pada pengamatan ke empat yakni 284 ind/m2, sedangkan kelimpahan terendah diperoleh pada pengamatan ke dua yakni 60 ind/m2. Produktivitas sekunder melingkupi P/B Rasio sebesar 3.034/bulan dengan kecepatan produksi 14.2458 (g/m2/bln) dan biomassa (4.6954 g/m2).

Abstract

Secondary productivity is the formation of biomass of heterotrophic organisms in units of time including biomass that is lost in a certain time unit. The Crambidae family is an insect that has aquatic larvae and will become an air insect after the larval phase. This species has the potential to become a pest for agriculture. The study was conducted in October 2019 for one month. The Crambidae family species found consists of two species, Petrophila sp. and Elophila sp. The abundance of Crambidae during the study ranged from 100 ind/m2 to 422 ind/m2. Secondary productivity was analyzed by the size frequency method. The secondary productivity of the Crambidae family in Cigambreng river waters for one month was 47.7915 g/m2/month, the biomass formed was 14.9669 g/m2 and the P/B ratio was 3.1931.
