Abstract

Polyculture of spiny lobster and rabbitfish is a cultivation system that combine two different types of fishery commodities in one cultivation container. The advantages are increased land productivity, efficient use of resources and diversification of cultivated production. This research aims to establish the effect polyculture of spiny lobster and rabbitfish on the stocking density of rabbitfish which is different from Floating Net Cage (FNC) system. The research was conducted in the coastal water Dusun Ujung Betok Pemongkong Jerowaru East Lombok. The size of the FNC used is 2m3. The weight of spiny lobster used ranged from 95-98g and the rabbitfish is 12-15g. The research was conducted using a Completely Randomized Design (CRD) with 3 treatments, A (30 spiny lobster/m3 without rabbitfish), B (30 spiny lobster/m3 and 5 rabbitfish) and C (30 spiny lobster/m3 and 10 rabbitfish). Based on the research result, it was found that the absolute weight gain of lobsters during 45 days of rearing was in the range of 10.7 g – 11.6 g. The absolute weight gain of rabbitfish was 14 g – 19.8 g. There is significance in the survival rate of spiny lobsters, where the best treatment is C 93.33%. The survival rate (SR) value for rabbitfish reaches 100%. The results of the study represented that polyculture of spiny lobsters and rabbitfish affected the productivity and survival rate of both species, but not their growth.

Abstract

Sea urchins are a highly nutritious and economically valuable fishery product. In West Nusa Tenggara (NTB), particularly in Lombok, the public is still largely unaware of the benefits and market value of sea urchins in international markets such as Japan and Korea. Sea urchin gonads are consumed by Koreans and Japanese, and their high nutritional content is believed to improve health performance. However, there are obstacles in the sea urchin market development is the lack of proper standard operating procedures in post-harvest handling. Appropriate and standardized post-harvest techniques are not yet widely known or disseminated among sellers and sea urchin business actors. Prima Nusantara Cooperative is one of the cooperatives that supplies fishery products, including sea urchins, to exporting companies. Based on this, the current community service activity was conducted at Prima Nusantara Cooperative in East Lombok, targeting the cooperative staff. The aim is to provide both theoretical socialization and hands-on training to enhance the staff’s knowledge and skills in post-harvest handling of sea urchins. Through this technical guidance, it is expected that the quality of sea urchin products sold to exporters will improve and be more competitive in the Japanese and Korean markets. The method used during the technical training included presentation of materials on proper sea urchin handling procedures, followed by field practice involving sea urchin sampling, hands-on demonstrations, and direct mentoring through each stage of the process. The post-harvest handling stages included harvesting (collection), cleaning, shell breaking, rinsing, weighing, packaging, and storage at low temperatures.

Abstract

Fish cultivation using the Floating Net Cultivation (FNC) system had the potential to create nutrient enrichment around the cultivation location. The large amount of nutrient input in marine waters can cause algae blooms also known as eutrophication. If this condition continues to occur, biota diversity will decrease and cause the seas to lose their function, so before that happens, it is considered to periodically monitor the pollution index in the Ekas Bay FNC area. The aim of this study is to analyze the pollution index in FNC area in the waters of Ekas Buana Village. The value obtained can be used as a basis for managing the area to create sustainable and sustainable use. The research was conducted in Ekas Bay, Ekas Buana village, East Lombok district on June-September 2023. The parameters observed were physical and chemical water quality parameters. The data that has been collected will be analyzed descriptively and presented in the form of tables and graphs. The parameter value obtained was the only one that passed the quality standard based on PP No. 22 of 2021, namely orthophosphate. Phosphate is indeed abundant in marine waters, but it will cause blooming if the total supply of ammonia nitrogen is excessive. From the pollution index, it was found that the East station, which is the coastal littoral area, is classified as moderately polluted, while the other stations are classified as lightly polluted. The sources and quantities of the pollution need to be identified to facilitate control and prevent further pollution.
