Abstract

Penanganan loin ikan tuna yang dimulai dari proses penerimaan hingga tahap pengemasan (packing) merupakan rangkaian kritis dakam menjaga mutu dan keamanan pangan produk perikanan. Penelitian ini bertujuan untuk mendeskripsikan alur proses penanganan loin tuna di PT Maritim Timur Perkasa, Kota Kupang, mulai dari penerimaan bahan baku hingga pengemasan terakhir, metode yang digunakan dalam penelitian ini yaitu observasi langsung alur produksi, wawancara dengan staf operasional, dan pencatatan kondisi suhu serta waktu penanganan tiap tahapnya. Hasil penelitian ini menunjukkan bahwa ikan tuna yang diterima langsung diperiksa mutu seta dilakukannya trimming dan retouching untuk memisahkan daging yang bagus dan daging yang tidak diinginkan. Potongan loin ini kemudian dibekukan di dalam Air Blast Freezer (ABF) hingga suhu sekitar -40 derajat celcius, yang kemudian dikemas menggunakan bahan food-grade dengan memberikan label mutu dan tanggal produksi lalu disimpan di dalam cold storage yang bersuhu -20 derajat celcius hingga proses pengiriman. Penanganan yang disertai dengan pengawasan mutu pada setiap tahapan pengolahan dan penanganan akan memberikan produk yang bermutu baik.

Abstract

Sea surface temperature (SST) is a key oceanographic parameter influencing the distribution and abundance of small pelagic fish in tropical waters. This study aims to analyze the effect of SST on small pelagic fish catches in Fisheries Management Area (FMA) 573. Catch data were obtained from the Fisheries Resource Center of Indonesia (FRCI) for the 2015–2021 period, while SST data were derived from Aqua MODIS satellite imagery with 4 km resolution, processed using Seadas 7.4 software. A simple linear regression was applied to examine the relationship between SST and fish catches. The results indicate a negative relationship, where each 1 °C increase in SST tends to reduce catches by approximately 35 thousand tons. The coefficient of determination (R²) of 0.531 shows that 53.1% of the catch variability is explained by SST, while the remaining is influenced by other factors such as primary productivity (chlorophyll-a), upwelling intensity, global climate phenomena (ENSO, IOD), and fishing pressure. These findings highlight SST as an important indicator for predicting fishing seasons in FMA 573 and emphasize the need to integrate satellite-based oceanographic data into Ecosystem-Based Fisheries Management (EBFM) to ensure sustainable fisheries in Indonesian tropical waters.
