<![CDATA[Skipjack tuna (Katsuwonus pelamis) is a pelagic fish that has oceanic characteristics that always migrate from one water to another that has oceanographic, biological and meteorological conditions that suit its habitat. Currently the use of geographic information system (GIS) technology is widely used in obtaining information about oceanographic characteristics, one of which is the use of satellite imagery data. With the collaboration between GIS and the latest satellite, namely Sentinel-3, it can determine potential fishing zones. The purpose of this study is to examine the effect of sea surface temperature parameters on catches to determine the potential zone for skipjack tuna fishing in the Makassar Strait Waters. This study uses a quantitative method, namely using primary data, namely collecting coordinate points of fishing and catches of skipjack tuna in the Makassar Strait Waters and secondary data, namely oceanographic parameter data in the form of sea surface temperature data obtained from Sentinel-3 satellite imagery during January and February, data analysis through a histogram of the relationship between skipjack tuna catches and SST oceanographic parameters, making a map of potential areas for skipjack tuna fishing using ArcGIS 10.8 software. The results of the study showed the optimum sea surface temperature range for catching skipjack tuna is 29 - 30oC with a catch of 841 - 1010kg and is at the coordinate point 118.1o - 118.3o East Longitude and 2.2o - 2.5o South Latitude. The optimum chlorophyll-a range is 0.1 - 0.4 mg/m3 with a catch of 655 - 738kg located at the coordinate point 117o - 118o East Longitude and 2.4o - 2.5o South Latitude.]]>
