Abstract

The coastal area of Lembar District, West Lombok, has great potential in cultivating marine ornamental fish such as clownfish and blue tang, but water pollution due to Lembar Port activities has caused a decline in water quality and low fish survival. This community service aims to increase the capacity of farmers in managing water quality through the application of protein skimmer technology, a tool that can remove dissolved organic particles from seawater. The activity was carried out in six stages, namely location survey, socialization, training, technology application, mentoring and evaluation, and program sustainability. The results of the activity showed that partners experienced an increase in understanding of the importance of water quality and skills in using protein skimmers. In addition, the condition of the cultivation environment became more stable and supported the growth of ornamental fish. With a participatory approach and the application of appropriate technology, this activity was able to provide a positive impact. This program is expected to be a pilot model for other coastal areas in the development of sustainable marine ornamental fish cultivation.

Abstract

This community service activity focused on developing feed production techniques using local raw materials for mud crab farmers in Madak Belek Hamlet, Sekotong District. The main challenge faced by farmers is the high cost of commercial feed, which reduces profit margins. In fact, the area is rich in underutilized nutrient-rich local resources such as trash fish and seafood processing by-products. A participatory approach was applied, including observation, socialization, demonstration, hands-on training, and evaluation. The training emphasized feed formulation and the application of 5% wheat gluten as a binder, which had been proven in preliminary studies to enhance feed stability in water. The results showed an improvement in participants’ knowledge and skills in processing local ingredients into quality feed. The expected impacts include reducing dependence on commercial feed, lowering production costs, and improving the efficiency and sustainability of mud crab farming. For further optimization, feed performance testing on crab growth and economic feasibility analysis are required.
