EFEKTIFITAS PENGGUNAAN LIMBAH PASIR SILIKA SEBAGAI PENGIKAT SUSPENSI TERHADAP KECERAHAN PERAIRAN MEDIA BUDIDAYA DAN LAJU PERTUMBUHAN UDANG VANAME (Litopenaeus vannamei) DI INSTALASI BUDIDAYA LAUT (IBL) BONCONG, KABUPATEN TUBAN

The purpose of this study was to determine the effectiveness of using silica waste as a suspension binder on the brightness of cultivation media waters and growth rates of vannamei shrimp at the Boncong Marine Aquaculture Installation (IBL), Tuban. This research is an experimental research. The experimental design used in this study is a complete randomized design (CRD). The treatment given was the provision of silica sand waste with three different doses, namely A = 45 grams / L, B = 54 grams / L and C = 63 grams / L. Each treatment was replicated 3 times. Each treatment was replicated 3 times with 1 control variable without treatment. Parameters tested included: brightness, salinity, temperature, pH, ammonia dissolved oxygen, daily growth rate (SGR) and survival (SR), from a maintenance period of 70 days. The feed dose given was FR = 7%. From this study it was concluded that the use of silica sand waste at a dose of 63 grams / L is the most effective dose to bind the suspension and increase the brightness value to 36,4 cm in the process of raising vanname shrimp at the Boncong Marine Aquaculture Installation (IBL), Tuban.
