Abstract

This study aims to analyze the parameters of water quality in Post larva (PL) 8 Vanamei shrimp (L. vannamei) by testing physical parameters (temperature, salinity, brightness) and chemical parameters (DO (dissolved oxygen), pH, alkalinity, and hardness. Research conducted at PT. Budi Agri Sejahtera (BAS), Tempilang District, West Bangka Regency, Bangka Belitung Province while conducted Program Kampus Merdeka Magang and Studi Independen Bersertifikat (MSIB). The method uses purposive sampling by setting 5 (five) observation points. Primary data in the form of in situ measurements of water quality parameters obtained in the field. While the analysis of chemical parameters were carried out in the laboratory of PT. BAS in the pond location. Secondary data was carried out by the information of company and journals related to this research. The results of this study indicate that temperature (25-30,2°C), brightness (20-40 cm), salinity (24-31 ppt), DO (3,7-6,3 ppm), pH (7,5-9), Alkalinity (102-150 ppm), Hardness (3,700-5,900 ppm). It was concluded that base on of SNI 01-7246-2006 and Ministry marine and fisheries No: KEP. 28/MEN/2004 the condition of the waters at PT. BAS is still suitable for PL 8 Vanamei shrimp (L. vannamei) cultivate. Keyword: Vaname Shrimp, Water Quality, PT. Budi Agri Sejahtera (BAS), Aquaculture

Abstract

The purpose of this study was to determine the type of vegetable plant as a biofilter in the aquaponics system that can trigger the growth of Nile tilapia (Oreochromis niloticus).  This study was designed using a Complete Randomized Design with 4 treatments, namely treatment A biofilter pakchoy plant, treatment B biofilter lettuce plant, treatment C biofilter red amaranth plant and treatment D without plant biofilter (control), each with three replications.  Fish were weighed at the beginning of the study and subsequently every week until the fourth week. Absolute growth and specific growth rate were evaluated while fish survival and water quality parameters were observed as supporting data. The results of the study found that pakchoy, lettuce, and red amaranth vegetable crops as biofilters in the aquaponics system had the same influence on the growth of tilapia (O. niloticus) but were significantly different from tilapia cultured without vegetable plant biofilters.   Keywords: Nile tilapia, aquaponic, water quality, aquaculture, fish growth
