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 waters of Dumai City, located in Riau Province and directly connected to the Malacca Strait, are highly accessible both locally and internationally. The coastal area is characterized by intensive human settlements and diverse industrial activities, including oil and gas, crude palm oil (CPO), and cement industries, which discharge wastes that may affect marine biota. Most of these wastes are transported to the sea through river flows, posing a serious threat to the ecological balance and aquatic organisms, particularly fish, with potential risks to human consumers. This study aimed to examine the physicochemical parameters of the waters and to determine the concentration and status of cadmium (Cd) and lead (Pb) in water, sediment, and fish. The research was conducted from April to June 2025 using survey, observation, and experimental methods in both field and laboratory settings. Data were analyzed using Atomic Absorption Spectrophotometry (AAS) to measure the actual concentrations of heavy metals. The results were compared with the threshold values established by the Indonesian Ministry of Environment Decree No. 51/2004 concerning marine water quality standards for aquatic biota. The findings revealed that the physicochemical parameters, including water temperature, salinity, and dissolved oxygen (DO), remain supportive of aquatic life according to the standards. However, the concentrations of Pb and Cd in water, sediment, and fish samples exceeded the permissible limits, indicating pollution in Dumai waters.
