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.

Abstract

Situ Patengan merupakan salah satu danau dataran tinggi di Jawa Barat yang berada pada ketinggian 1600 mdpl. Danau dataran tinggi memiliki karakteristik unik dan dihuni oleh berbagai organisme di dalamnya termasuk makroavertebrata bentik. Tujuan dari penelitian ini adalah mengkaji biodiversitas makroavertebrata bentik pada tingkat famili serta hubungannya dengan kondisi lingkungan perairan. Kajian ini dilaksanakan dari Agustus hingga Oktober 2022 pada tiga area dengan 9 titik pengamatan. Hasil dari penelitian ini didapatkan 9 famili (Atyiidae, Glossiphonidae, Isotomidae, Chironomidae, Culicidae, Perlidae, Naididae, Lumbriculidae dan Tubificidae) yang berasal dari 6 ordo. Famili Chironomidae merupakan famili yang mendominasi dari sisi jumlah jenis dan kelimpahan. Berdasarkan Canonical Correspondence Analysis (CCA), setiap area pengamatan memiliki karakteristik perairan yang berbeda-beda serta korelasi dengan makroavertebrata bentik sesuai dengan tekanan lingkungan yang ada di sekitar area tersebut. Meskipun beberapa area memiliki tekanan lingkungan yang cukup tinggi, masih ditemukan jenis-jenis makroavertebrata yang sensitif terhadap tekanan lingkungan seperti famili Atyiidae maupun Perlidae terutama di area yang tekanan lingkungannya relatif rendah terutama di sekitar area hutan lindung.
