Abstract

Penelitian dilaksanakan di perusahaan dock dan perkapalan PT. Perikanan Indonesia, PT. Tiara, dan koperasi unit desa (KUD) Karya Mina di kota Tegal Jawa Tengah. Waktu pelaksanaan pada bulan Oktober 2023. Tujuan penelitian ini adalah untuk menentukan persentase perubahan bentuk badan kapal di bawah dek, nilai Cb (coefficient block) dan GT (gross tonnage) kapal purse seine di wilayah Tegal dengan pendekatan model yang dicelupkan dalam air. Penelitian Cb dan GT difokuskan pada KM. Himalaya SB dengan akurasi 84,44%. Hasil penelitian di ketiga perusahaan dock dan perkapalan tersebut diperoleh bahwa perubahan bentuk badan kapal di bawah dek rata-rata bagian I, II, III, IV, and V adalah masing-masing 14%, 20%, 30%, 11%, dan 25%, sedangkan pada contoh kasus KM. Himalaya SB bagian I, II, III, IV, and V adalah masing-masing 15%, 18% , 29%, 9%, dan 29%. Bentuk didominasi oleh bentuk III dan V, yang memberikan peningkatan nilai Cb dan GT adalah bentuk III dengan bentuk U. Hasil rata-rata persentase perubahan bentuk dari 6 buah kapal termasuk di dalamnya kapal purse seine contoh kasus mempunyai pola yang cenderung sama. Nilai Cb hasil percobaan diperoleh 0,82 > 0,70 dari koefisien faktor “f” sesuai Permenhub Nomor 8 Tahun 2013. Berdasarkan perhitungan GT, didapat peningkatan nilai sebesar 17% jika dibandingkan dengan permen tersebut.

Abstract

Pekalongan National Fishing Port (PPN Pekalongan), a type B fishing port, is recognized for its well-managed facilities and serves as an operational base for purse seine vessels. Purse seines are widely employed to harvest schooling pelagic fish, most of which are species of high economic value, thus requiring appropriate handling to maintain quality. This study aims to examine the handling practices of purse seine catches on board KM. Bintang Mas Maritim, focusing on storage temperature, handling equipment, and storage duration under freezer-based systems. Data collected included fish temperature at hauling, during freezing, and after storage, as well as the handling methods and equipment used by fishermen. The initial body temperature of the fish was 29.3°C at hauling. Fish were sorted by species, size, and quality, then washed and frozen at -18°C for 24 hours. Once frozen, they were packaged and transferred to the fish hold at -13.7°C for storage. The findings highlight the importance of systematic handling, washing, rapid freezing, and controlled storage—to maintain fish quality and extend shelf life.

Abstract

The blue swimming crab is a leading commodity in Karawang Regency in terms of economic value. It is marketed locally and internationally. Blue swimming crabs are sold to consumers both alive and processed, so a supply chain process is needed that can meet consumer demand quickly and maintain excellent quality. This study aims to analyze the management, structure, and costs of the blue swimming crab supply chain and evaluate its external performance using the Supply Chain Operations Reference (SCOR) method, which is considered a systematic approach for measuring supply chain performance. This study was conducted in Tirtajaya District, Cilamaya Wetan District, and at a blue swimming crab processing company in Cirebon. The results of this study include an explanation of the supply chain targets, supply chain structures, types of costs incurred by fishermen, traders, collectors, and suppliers, as well as the value of the external performance of the supply chain. The research subjects consisted of fishermen, traders, and collectors. The structure of the blue swimming crab supply chain in Karawang Regency had two different flows or chain networks from fishermen to suppliers. The costs generally incurred are operational costs, including diesel fuel, supplies, fishing gear, bait (if using traps), and transportation. External performance measurements of the blue swimming crab supply chain in Karawang Regency consistently yield superior results across all indicators. However, the order fulfillment indicator yielded parity due to the lean season.
