Abstract
Kebumen merupakan salah satu wilayah di Jawa Tengah yang salah satu komoditas hasil tangkapannya yaitu ikan kembung (Rastrelliger sp.). Kegiatan penangkapan ikan nelayan Kebumen masih menggunakan cara tradisional yang mana berdasarkan pengalaman para nelayan dan mengikuti tanda-tanda alam seperti iklim, cuaca, dan lain-lain. Tujuan dari penelitian ini adalah untuk mengetahui sebaran klorofil-a dan suhu permukaan laut di Perairan Kebumen Jawa Tengah serta untuk menganalisis daerah potensi penangkapan ikan kembung yang ideal di Perairan Kebumen berdasarkan hasil citra satelit Aqua MODIS. Metode yang digunakan yaitu kuantitatif deskriptif. Data citra yang diambil pada bulan Juli hingga Agustus 2021-2023 diolah menggunakan software ArcGis setelah cropping di SEADAS. Hasil penelitian menunjukan bahwa nilai konsentrasi klorofil-a dan suhu permukaan laut di Perairan Kebumen mengalami fluktuasi selama 3 tahun terakhir. Nilai rata-rata klorofil-a yang paling tinggi selama 3 tahun terakhir yaitu bulan Agustus 2023 dengan konsentrasi 26,02 mg/m3 sedangkan suhu permukaan laut tertinggi terjadi pada bulan bulan Desember 2022 yang mana suhunya 31.60C. Penggabungan citra klorofil-a dan suhu permukaan laut disebut overlay dimana proses tersebut menghasilkan titik daerah potensi ikan kembung (Rastrelliger sp.). Berdasarkan overlay citra di Perairan Kebumen yang terletak pada 7027’-7050’LS hingga 109022–109050’BT menghasilkan titik tertinggi pada bulan Oktober 2023 dengan 167 titik. Kebumen is one of the regions in Central Java where one of the commodities caught is Mackerel fish (Rastrelliger sp.). Kebumen fishermen's fishing activities still use traditional methods which are based on the experience of the fishermen and follow natural signs such as climate, weather, and others. The purpose of this study was to determine the distribution of chlorophyll-a and sea surface temperature in the waters of Kebumen, Central Java and to analyze the potential areas of ideal mackerel fishing in Kebumen waters based on the results of Aqua MODIS satellite imagery. The method used is descriptive quantitative. Image data taken from July to August 2021-2023 was processed using ArcGis software after cropping in SEADAS. The results showed that the value of chlorophyll-a concentration and sea surface temperature in Kebumen Waters fluctuated over the past 3 years. The highest average chlorophyll-a value during the last 3 years was in August 2023 with a concentration of 26.02 mg/m3 while the highest sea surface temperature occurred in December 2022 where the temperature was 31.60C. The merging of chlorophyll-a and sea surface temperature images is called overlay where the process produces a point of potential mackerel (Rastrelliger sp.) area. Based on image overlay in Kebumen Waters located at 7027'-7050'LS to 109022-109050'BT, the highest point was produced in October 2023 with 167 points.
