Abstract

Fish resources have limits; therefore, it is necessary to carry out appropriate management so that resource utilization is sufficient for a long time. Areas used as fishing businesses need to know how the level of utilization. For this reason, clear information is needed on the potential and level of utilization of marine fisheries resources to support the management policy of tuna resources for optimal management and utilization and to prevent the reduction of fish stocks in the future. This research was conducted for three weeks in July 2023 at Bungus Ocean Fishing Port (PPS), Padang City, West Sumatra Province. The method used in this research is a survey method or direct review of the field. The maximum sustainable potential value was obtained at 572.36 tons with an optimum utilization effort value of 330 trips. The allowable catch of longtail tuna is 457.89 tons, with an average utilization rate of 97.41%. Based on the average value of the utilization rate obtained from 2018 to 2019, the number of allowable catches, and the MSY value, it is concluded that the longtail tuna caught by bagan boats and Tonda fishing rods at PPS Bungus has experienced overfishing. There is a need for more action and monitoring of the amount of catch obtained each year, as well as limiting the amount of catch allowed for each fisherman so that the utilization rate of longtail tuna can return to optimal catch and prevent overfishing and maintain fish stocks for the future.

Abstract

The development of seaweed cultivation by farmers cannot be separated from production factors such as capital, seeds, labor, and land area, which greatly support the success of seaweed cultivation. This study aims to analyze the factors affecting seaweed production and how to return to scale. The research was conducted in Pantai Amal Village. The number of samples in the study was 59 seaweed farmers using the incidental sampling method. The data analysis technique used multiple linear regression analysis in the form of the Cobb-Douglas function logarithm using the SPSS 26 software. The results showed that simultaneously the capital factors (X1), seeds (X2), labor (X3), and land area (X4) jointly affect the production (sig=0.00). Only the farmer's capital partially showed a significant effect (0.00) smaller than the significance level of = 0.05. The business scale has shown increasing returns to scale with a coefficient value of 1.15, which means that all inputs used in production are increased by 1. The resulting production will be increased by 1, and the resulting production will increase by a more significant proportion, namely 1.15. Thus, seaweed farmers’ use of production factors is efficient.

Abstract

This study aims to determine the perceptions of local communities towards marine sand mining activities in the Kepulauan Riau Province. Considering the region's dominance, Kepulauan Riau has great potential for sand mining in terms of quality and quantity. The population dynamics and high development today encourage an increased need for sand. Therefore, sand mining businesses have become social, economic, and ecological. This research uses a descriptive qualitative approach with an interview method with 60 respondents. Multiple linear regression analysis was used to predict perceptions based on social, economic, and ecological variables. The results showed that social aspects (coefficient value of 0.809) strongly influenced the sustainability of mining activities compared to ecological aspects (0.271) and economic aspects (-0.045). This finding shows that if mining activities can create good social conditions in local communities, sand mining activities can continue. However, these social conditions are related to the ecological impacts caused by mining.
