Abstract

The Polyculture Caulerpa sp and Litopenaeus vannamei can reduce the risk of ecological impacts, increase shrimp growth, survival, production, increase shrimp resistance to disease, and maintain optimal water quality. Analytical Hierarchy Process (AHP) begins by determining the priority between water quality, growth rate, and harvest yields as more optimal parameters for the success of a polyculture. The measure of success is determined based on the results of expert assessments of polyculture and cultivation that produce more optimal water quality (temperature, pH, brightness, salinity, and dissolved oxygen), growth rates, and harvest yields. The results of the overall AHP analysis, which determined the success of Caulerpa sp and Litopenaeus vannamei polyculture based on expert assessments, showed a good level of consistency. The results show that water quality is a priority parameter in the success of Caulerpa sp and Litopenaeus vannamei polyculture with a weight of 0.597, followed by a growth rate of 0.297 and a harvest yield of 0.106. The analysis of priority water quality indicators for the success of polyculture is dissolved oxygen with a weight of 0.514, followed by pH of 0.246, salinity of 0.119, temperature of 0.079, and brightness of 0.042. Based on the results of experts of the combined weight comparison, polyculture is more optimal than cultivation, with a considerable comparison weight of 0.678 and 0.322, measuring the success of Caulerpa sp and Litopenaeus vannamei polyculture.

Abstract

Central Tapanuli Regency is a region that has significant potential in the fisheries sector, mainly traditional fisheries, due to its extensive mangrove ecosystem and lengthy coastline. Mangroves are essential for the livelihood of local fishing, as they protect the marine environment and serve as a barrier against coastal erosion. The mangrove ecosystem in Central Tapanuli Regency is experiencing increased pressure due to land conversion, illicit logging, and other human activities, as research surveys indicate. This pressure has a negative impact on the productivity of catches and the welfare of fishermen. This risk is undoubtedly a significant concern; the ecological value of the mangrove ecosystem may be diminished, resulting in a decrease in the catch of local trap fishermen. Consequently, this research is necessary for the local government to reference when developing mangrove management strategies. This investigation aimed to assess the state of the mangrove ecosystem in Tapian Nauli Bay and the correlation between mangrove conditions and the socio-economic status of crab trawl fishermen. The investigation was conducted in Central Tapanuli, specifically in Tapian Nauli Bay. Surveys and interviews with respondents were implemented to accumulate data. Descriptive and correlational analyses are implemented. The results of this study indicated that 60% of the mangroves in Tapian Nauli Bay were in excellent condition, while only 30-40% were in poor condition. The income of bubu fishermen is significantly influenced by the presence of mangroves, as the catches they capture increase, thereby improving their livelihoods.
