Abstract

Indonesia as an archipelago with vast marine areas, has a large and diverse fisheries potential and can become one of the leading economic sectors if managed properly. However, the management and utilization of fisheries resources in this country are not optimal because most fishermen and related parties still rely on traditional methods in determining fishing areas. This study aims to map the Zone of Fishing Potential in the Makassar Strait waters using Sea Surface Temperature and chlorophyll-a distribution data for the period May 2024. The results of this study indicate that water areas with suitable chlorophyll-a concentrations (0.2-1.5 mg/m3) combined with optimal sea surface temperatures (between 28°C-30°C) tend to be productive zone of fishing potential. Areas around the coast of Makassar and Polewali Mandar appear to have high potential in supporting such activities.

Abstract

Banyuwangi Regency has 282 km of coastline with high coastal potential to be developed, such as tourism, fisheries, and ports. This study aimed to analyze the suitability of the Tanjung Wangi Port location based on tidal and ocean current data. Tidal data were obtained from the Indonesian Hydrographic Data Center (IHDC), and ocean current data were obtained from AVISO Satellite Altimetry. The data were processed using Microsoft Excel and ArcGIS using the inverse distance weighted (IDW) method to create ocean current maps. The results showed that Tanjung Wangi Port has a double-dominant mixed tidal type. The highest water level was recorded at 5.207 m, and the lowest water level was 0.809 m, with a Mean Sea Level (MSL) of 3.048 m. The sea current speed ranged from 0.023 m/s to 1.414 m/s from the Southeast and Southwest Indian Ocean, with the direction of the sea current towards the Banyuwangi Regency. Stable tidal conditions and low ocean currents make the Tanjung Wangi Port ideal for safe harbor and navigation activities and contribute positively to the effectiveness of port activities. Further research should involve direct field surveys and seasonal variability analyses to improve the accuracy of port planning.
