Abstract

The increase in nutrients (nitrate, orthophosphate, and silica) will affect the microphytes as primary producers in the Pelus River ecosystem. This research aims to study NO3, PO4, Si(OH)4 concentration, the community structure of planktonic and benthic microphytes, and also the correlation between NO3, PO4, Si(OH)4 concentration with the benthic microphytes abundance in the Pelus River. The method used for this research was a survey method. Data were analyzed by calculating the community structure of planktonic and benthic microphytes, while quantitative analysis used indexes. The correlation between nitrate, orthophosphate, and silica concentrations was analyzed by multiple regression. The results showed that the composition of planktonic microphytes consisted of 34 species with an abundance of 41,637 ind.l-1, while benthic microphytes consisted of 54 species with an abundance of 89,908 ind.cm-2. The benthic microphytes community had moderate diversity (H'=1.50-2.58) and no dominant species (C=0.11-0.35). Individuals between species were not evenly distributed in each station (E=0.40-0.44). The correlation between nitrate, orthophosphate, silica concentration with the benthic microphytes abundance was very tight (r=0.999). The determination coefficient R2=0.998 indicated that the benthic microphytes abundance was influenced 99.8% by nutrient concentration. The remaining 0,2% was influenced by other factors such as current velocity and light penetration.

Abstract

Wisata Hutan Payau Tritih Kulon merupakan penyangga Kawasan Segara Anakan yang dilindungi. Sebagian besar tanaman mangrove yang berada di Wisata Hutan Payau Tritih Kulon yaitu Rhizophora sp. Bioindikator yang biasa diamati di kawasan ini adalah makrozoobentos yang hidup di dasar perairan ataupun melekat pada pepohonan mangrove. Tujuan dari penelitian ini yaitu mengkaji tentang kerapatan Rhizophora sp. dan kelimpahan Makrozoobentos serta hubungan antara Rhizophora sp. dengan Makrozoobentos di Mangrove Tritih Kulon, Cilacap. Metode penelitian menggunakan metode survei dengan 3 stasiun. Pengambilan sampel dilakukan pada bulan November–Desember 2022. Analisis dilakukan secara deskriptif dan regresi menggunakan software Microsoft Excel. Hasil penelitian menunjukkan bahwa kerapatan Rhizophora sp. di mangrove Tritih Kulon, Cilacap sekitar 1.625–2.167 ind/ha. Kelimpahan makrozobentos setiap stasiun berkisar antara 189–296 ind/m2. Kerapatan Rhizophora sp. dengan kelimpahan makrozoobentos memiliki hubungan positif dengan persamaan y=0,0221x + 35,365.
