Abstract

Copepoda merupakan salah satu kelompok yang mendominansi populasi zooplankton di perairan. Kelimpahan copepoda dapat dijadikan sebagai indikator suatu perairan karena merupakan salah satu makanan bagi ikan pelagis. Penelitian ini bertujuan untuk mengetahui distribusi kelimpahan copepoda dan hubungan kelimpahan terhadap kualitas perairan di Muara Sungai Musi. Adapun metode yang digunakan pada penelitian ini adalah persiapan sampling, penentuan titik stasiun, sampling copepoda, perlakuan terhadap sempel, pengambilan data kualitas perairan, dan perhitungan serta identifikasi copepoda. Hasil identifikasi didapatkan 9 jenis copepoda diantaranya Nauplius sp., Acartia, Oithona Fullox, Oithona Similis, Rhicalanus sp., Calanus sp., Podoplea, Cyclopoida, Paracylopoida. Kelimpahan copepoda yang didapat adalah 3 ind/l sampai dengan 193 ind/l, Keanekaragaman 0,7 - 1,6 dengan kriteria sedang, Keseragaman tinggi dengan jumlah 0,3 sampai 0,7 serta dominansi rendah dengan nilai ,2 sampai dengan 0,5. Hasil dari PCA dengan menggunakan XLSTAT didapatkan penciri berupa keanekaragaman, keseragaman, salinitas, pH, DO dan fosfat. Parameter kualitas perairan menunjukan hasil yang normal dan baik untuk keberlangsungan hidup copepoda. Kata Kunci : Muara Sungai Musi, Kelimpahan Copepoda, Parameter Kualitas Perairan Capepod is one of the groups that dominates the zooplankton population in waters. The capepod abundance can become an indicator in waters because it is one of the foods for pelagic fish. The purpose of this study was to determine the distribution of capepod abundance and the relationship between zooplankton abundance and water quality in the waters of the river musi estuary. The methods used in this research were preparation of sampling, determination of station site, capepod sampling, sampling treatment, taking of water quality data, calculation and identification of capepod. The results of identification were found 9 types of capepod including nauplius sp., Acartia, lithonia fullox, lithonia similis, rhicalanis sp., Calanus sp., Peoplea, cyclopoida, paracylopoida, the capepod abundance was found with ranges from 3 ind/l - 193 ind/l. The Diversity index was included in the middle criteria ranges from 0,7 – 1,6, the uniformity index was included in the high criteria ranges from 0,3 – 0,7 and dominance index was included in the low criteria ranges from 0,2 – 0,5. The results of PCA using XLSTAT were obtained with the characteristics of diversity, uniformity, Salinity, pH, DO and phosphate. The results of water quality parameter show normal and good for survival of capepod. Keywords: Musi River Estuary, Copepod Abundance, Water Quality Parameters
