Abstract

The objective of this study was to analyze the dynamics community structure of Cyanobacteria and trophic status in ponds of intensive shrimp culture (Litopenaeus vannamei) in Situbondo based on Trophic Diatom Index (TDI).  The ex post facto research was conducted in situ in the hamlet of Pond Mutiara Mas III Klatakan Situbondo East Java Indonesia.  Observation of Cyanobacteria and Diatoms community structure were done every week during four cycles of shrimp farming ponds.  Cycle of shrimp farming ponds is the times for enlargement process of the shrimps from seed to mature which ranges from 90-120 days.  The dependent variables were the density of Cyanobacteria and Diatoms community, as well as chemical parameters nitrite and orthophosphate.  Trophic status was determined from TDI be counted from data of diatom density.  All of the data were then classified using cluster and biplot analysis program PAST Ver. 3.11 to discribe the profile of ecosystem quality.  The research results showed that there were four taxa of Cyanobacteria during farming cycle which the highest density was found from the genus of Oscillatoria.  Based on the value of TDI, we found that the trophic status of water in shrimps pond during the production process was eutrophic until hyper-eutrophic.  The water quality was decreases along with the length of incubation time.

Abstract

The aims of study are to analyze the effect of dissolved nitrate and phosphate content of the intensive shrimp farming pond Situbondo to maximum growth rate and carrying capacity of Oscillatoria population density in the laboratory. This is an experimental research method using completely randomized design with three replications. The treatment were variation of nitrate and phosphate concentration (N0; N6; N12; N24; N48; P0,2; P0,4; P0.8, P1.6  mg.L-1).  Experiment was done using a pure Oscillatoria culture in condition 25 watt lamp; 12 hours a day. The initial amount of Oscillatoria cells used for the treatment is 8 - 15 x 104 cell.mL-1. During the incubation process, chemical parameters were also observed including nitrate, phosphate, DO, and pH at the beginning of the incubation period. Oscillatoria cell was count every day until stationary phase for 30 days. Furthermore, a different test between treatments was conducted to determine levels of nitrate and phosphate in triggering the blooming of Oscillatoria using Oneway ANOVA analysis with SPSS Program. The results showed that the intensive shrimp pond waters of Situbondo already contain dissolved phosphate between 0.4 - 0.5 mg.L-1. Oscillatoria growth is strongly influenced by dissolved phosphate content in waters, phosphate levels of 0.2 - 0.4 or equivalent to the actual level of 0.6 - 0.7 mg.L-1 can cause the highest abundance of Oscillatoria that could endanger the ecosystem.  Keywords: dissolved phosphate, intensive shrimp farming, Nitrate, Oscillatoria.

Abstract

Kenaikan jumlah penduduk akan mengakibatkan naiknya volume sampah yang dihasilkan dari aktivitas antropogenik. Penelitian ini dilakukan di Pantai Sendang Biru dan Pelabuhan Perikanan Pondokdadap, Kabupaten Malang. Minimnya informasi mengenai karakteristik sampah laut juga tingkat kebersihan lingkungan pantai dan pelabuhan menjadi alasan perlunya penelitian ini dilakukan untuk mengetahui penanganan sampah laut yang lebih tepat. Tujuan dari penelitian ini adalah untuk mengidentifikasi jenis sampah laut, menganalisis kelimpahannya, serta menentukan tingkat kebersihan wilayah pesisir berdasarkan indeks kualitas kebersihan Clean-Coast Index (CCI) dan General Index (GI). CCI digunakan untuk menghitung tingkat kebersihan berdasarkan keberadaan sampah plastik saja, sedangkan GI menentukan kebersihan pantai berdasarkan semua kategori sampah. Pengambilan data sampah laut dilakukan dengan menggunakan kuadran transek berukuran 5 x 5 m pada area pantai dan pelabuhan. Identifikasi sampah berdasarkan kategori dilakukan secara langsung di lapang, termasuk penghitungan jumlah dan berat sampah. Sampah plastik merupakan kategori sampah yang mendominasi dengan persentase 73,25 % di Pantai Sendang Biru dan 68 % di Pelabuhan Pondokdadap. Sub-kategori sampah plastik yang mendominasi yaitu plastik sekali pakai dengan persentase 84,28 % di Pantai Sendang Biru dan 90 % di Pelabuhan Pondokdadap. Hasil perhitungan CCI mengkategorikan Pantai Sendang Biru (32.32 ± 17.63) dan Pelabuhan Pondokdadap (48,60±9,50) serta GI Pantai Sendang Biru (44,12 ± 19,52) dan Pelabuhan Pondokdadap (74,3 ± 20,28) termasuk ke dalam kategori sangat kotor, sehingga diperlukan tindakan pemulihan kawasan yang tercemar hingga kembali pada kondisinya semula, dan juga monitoring sampah secara berkelanjutan.
