Abstract

This study aims to map benthic habitats in the coastal area of Nongsa, Batam, using Sentinel-2A satellite imagery processed using the Random Forest (RF) algorithm on the Google Earth Engine (GEE) platform. The study area includes Teluk Mata Ikan, Tanjung Bemban, and Batu Besar, Nongsa District, Batam City, Kepulauan Riau Province. Field data were obtained through snorkeling surveys and underwater photo documentation in 16-18 August 2024. The four main habitat classes that were successfully identified include coral, sand, seagrass, and rubble (dead coral fragments). The classification results show the dominance of non-living substrates in the form of sand and rubble in most of the study area, while seagrass and coral are distributed in a limited area. Validation of the classification results produced an Overall Accuracy value of 89.90%, indicating a very good level of classification accuracy and suitability. The combination of Sentinel-2A imagery, RF algorithm, and GEE has proven to be effective, efficient, and replicable for mapping tropical benthic habitats spatially and periodically as a basis for sustainable coastal area management.

Abstract

Continuous and uncontrolled fishing of red snapper will cause fish stocks to degrade, while there is no recruitment process and if caught without good management. Therefore, it is necessary to study the estimation of the sustainable potential of red snapper. The purpose of this study was to calculate Catch Per Unit Effort (CPUE) and assess the value of Maximum Sustainable Yield (MSY) and Total Allowable Catch (TAC/JTB) of red snapper. The research was conducted at Sibolga VAT with survey data collection method, while the surplus production method with Schaefer model. The results showed that the standardized CPUE value in 2018 was 0.060 tons/trip, in 2019 it decreased to 0.037 tons/trip, in 2020 it decreased to 0.029 tons/trip, in 2021 it increased to 0.041 tons/trip, and in 2022 it increased to 0.060 tons/trip, then a decrease occurred again in 2023 which was 0.055 tons/trip. The overall CMSY value calculated using the Scheafer model was 122.2 tons, so it can be concluded that the fishing status is fully exploited and overfished. While the FMSY value is obtained at 3201 trips, where the status is overfished and fully exploited because the fishing effort each year is above the FMSY value. The total allowable catch (TAC/JTB) is 97.8 tons.

Abstract

Purse seine fishing gear has advantages in the efficiency of catching large quantities of pelagic fish and is considered environmentally friendly because it does not damage the seabed. Handling fish catches from purse seine fishing gear at the Sadeng Coastal Fisheries Port (PPP), there are two types, namely by using salt and ice which can maintain freshness and increase the selling price. This shows that the feasibility of purse seine using ice and salt can improve community welfare and is feasible to be developed. The purpose of this study is to analyze operational activities (construction, fishing gear operating techniques, area and season of operation, size of vessels and engines) and the feasibility of purse seine fishing gear at the Sadeng Beach Fishing Port. The research was carried out by descriptive method, sampling by purposive sampling. The analysis was carried out by explaining the operation activities of the purse seine ship from preparation, determination of fishing areas, travel, the process of capture, transportation and management of catches on board, and landing. The 35 GT purse seine catching unit has a lower fixed cost because the depreciation costs and licensing fees that must be incurred are lower than the 45 GT purse seine fishing unit. Based on calculations, an average R/C value of 1.3121 was obtained. This indicates that the R/C value > 1, which means that the venture is profitable and worth developing.Keywords: Feasibility, Fishing Gear, Purse Seine,  Sadeng Beach Fishing Port
