Abstract

Decreasing seaweed aquaculture in Panjang Island was allegedly affected by deterioration of water quality after the expansion of industry in Banten Bay. Thus, it is important to evaluate the growth performance of Kappaphycus alvarezii in the lead-contaminated farming area. The study took place in Panjang Island and Lontar waters to compare the growth performance of K. alvarezii in a high and low lead-exposes farming area. The seaweed farmed for 30 days by using a long-line method. Water samples collected four times with an interval of 10 days. Specific growth rate, temperature, pH, salinity, water motion, Secchi depth, and depth of the water were the parameter measured. The results show a high lead concentration in Panjang Island with the value of 0.024-0.046 mg/L, while in Lontar waters, the concentration was 0.020-0.026 mg/L. Even though Panjang Island has higher lead concentrations, but the weight growth of the seaweed from Panjang Island was higher than the seaweed from Lontar waters with the seaweed weight of 439.92 g compared to 239.13 g, respectively. The growth performance of K. alvarezii was not affected by the pollution when other environmental factors were suitable for the growth of this seaweed. Higher growth performance of K. alvarezii in high polluted area was supported by suitable other environmental factors LoA, Kor

Abstract

Daerah Aliran Sungai (DAS) Cibanten berhulu di Situ Cibanten yang merupakan kumpulan mata air dan kemudian mengalir hingga sejauh ± 42,07 Km dan bermuara di perairan Teluk Banten. Penelitian ini bertujuan untuk menginventarisasi jenis-jenis ikan di DAS Cibanten. Pengambilan sampel dilakukan pada bulan Mei-Juni 2017 dan pada bulan Oktober 2018 di daerah hulu, daerah tengah dan daerah hilir dari DAS Cibanten. Data dianalisis keanekaragaman dengan Indeks Shannon-wiener diversity index dan Index of Biotic Integrity. Selama penelitian didapat 80 ekor ikan dari 6 spesies, yaitu Tor sp., Rasbora aprotaenia, dan Puntius sealei di Hulu DAS; Barbonymus gonionotus dan Pterygoplichthys pardalis di Tengah DAS; serta Dermogenys pusilla di Hilir DAS. Berdasarkan nilai indeks keanekaragaman dan Index of Biotic Integrity, kesehatan ekosistem di DAS Cibanten sudah terganggu terutama di bagian tengah dan hilir.
