Study of Grouper Cultivation Integrated with Salt Production in Crystallization House

Abstract

-This research was conducted to determine the effectiveness of integrated innovations of salt production and grouper cultivation in crystallization houses on the quality and quantity of grouper fish cultivated in the coastal area of Lekok District, Pasuruan Regency. Grouper cultivation is carried out in a 3×2×1 meter pond using the cyclic aquades system (CAS). The CAS system in innovation is supported by a filter composed of natural ingredients that are easy to obtain to filter pond water as a cultivation medium. CAS system aims to filter impurities in the water so that the water quality in the pond is maintained to support the life of groupers. In 12 months, grouper fish are harvested twice, averaging 120 kg. From the Cost Benefit Analysis, the ROI (Return on Investment) is about 100.76%, and the payback period is about six months. The results of the Cost-Benefit Environment Analysis show that grouper cultivation with this innovation is environmentally friendly because the CAS system supports it. Thus, grouper cultivation using this innovation is feasible to continue to increase the income of coastal communities in Lekok District, Pasuruan Regency.
