Abstract

This study aims to determine the Structure of Polychaeta Community, and how the physical and chemical conditions and describe water conditions based on aquatic biota. The research time took place in April – October 2020. The determination of the sampling location was carried out using the Purposive Sampling method, which is based on differences in environmental baseline around. Identification of polychaeta samples was carried out at the Animal Ecology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Sriwijaya University, Indralaya. The results obtained 22 polychaeta genera consisting of 22 classes namely Sternaspidae, Arenicolidae, Ctenodrilidae, Parergodrilidae, Magelgnidae, Heterospionidae, Capitellidae, Scalibregmidae, Ophellidae, Pontodoridae, Pisionidae, Hesionidae, Eunicidae, Flabelligeridae, Fauveliopsidae, Neriophilidae, Culiridae Cossuridae, Alciopidae, and Nereididae. The species diversity index belongs to the medium category, which ranges from 1.8 to 2.81. The dominance index of polychaeta in the coastal waters of the Banyuasin mangrove is relatively small or no species dominates because all stations have an average dominance index value below 0.5. While the physico-chemical factors of the waters in this river are classified as stable.

Abstract

Penelitian tentang struktur komunitas plankton dan kualitas air. Penelitian tentang Struktur Komunitas Plankton di wilayah Sungai Komering di Kota Palembang, Sumatera Selatan telah dilakukan pada bulan Februari - April 2017. Lokasi pengambilan sampel adalah Penentuan berdasarkan metode Purposive Sampling, yaitu berdasarkan perbedaan lingkungan sekitar. Identifikasi sampel plankton dilakukan di Laboratorium Ekologi Hewan, Departemen Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Sriwijaya, Indralaya. Hasil penelitian genera 16 plankton terdiri dari 10 kelas: Bacillariophyceae, Chloropyceae, Fragilariophyceae, Cyanophyceae, Xanthophyceae, Flagellata, Rizophoda, Crustacea, Branchiopoda, dan Nematodes. Kisaran kelimpahan Plankton di Sungai Komering rendah antara 1 individu / liter - 91 individu / liter. Indeks keanekaragaman spesies di mana 0,88-1,18, tambang ini adalah kategori sedang. Indeks Dominan Plankton di stasiun 3 dan merupakan genera dominan, dengan nilai 4 0,56 dan 0,62, yang menunjukkan keberadaan spesies plankton yang mendominasi dan berdasarkan nilai indeks kesamaan menunjukkan bahwa antar stasiun penelitian memiliki kemiripan yang tinggi Mulai dari 40% - 82%. Sedangkan faktor fisik-kimia di perairan sungai tergolong stabil.
