The impact of noise in the working area of fishing vessels should be understood, and effective noise reduction strategies should be identified to protect the health and performance of crew members in the workplace. This study aims to evaluate the level of noise in the working area of fishing vessels using a sound level meter during fishing operations. The study involved direct field data collection to obtain accurate and representative information on the noise levels experienced by the crew during fishing operations. Areas evaluated for noise levels include the engine room, deck, crew quarters, stern, and bow of the vessel. Data used for the study were collected from KM Nelayan Jaya, a fishing vessel equipped with a purse seine fishing gear, measuring 28.45 meters in length and powered by a 300 HP diesel engine. Noise levels were evaluated based on the IMO standard for noise exposure in the workplace, which recommends an average exposure limit of 80 dBA over 24 hours. The results of this study provide information on areas that exceed the specified standard noise levels and identify effective noise reduction strategies to protect the health and performance of crew members while improving the operational efficiency and overall sustainability of fishing vessels.

Sentani Lake in Papua Province is a significant ecosystem with multiple functions as ecological, economic, tourism, and transportation purposes. Unfortunately, the lake has been subject to pollution and damage due to human activities which degrade the riparian and water catchment areas, declining the endemic fauna. Settlements, transportation, agriculture, mining, and floating net cage cultivation (KJA) for fishery purposes also contribute to the decrease in water quality. In this study, in-site and ex-site water analysis was performed to assess the water quality and pollution status of Sentani Lake. The pollution index (IP) was used as the parameter of water quality status and pollution level. Some parameters were assessed: temperature (30.4 ^oC â€“ 33.3 ^oC), total suspended solids (TSS) (70 â€“ 89 mg/l), clarity (1 m - 5.2 m), pH (8.36 - 8.48), dissolved oxygen (DO) (5.74 mg/l â€“ 6.43 mg/l), biochemical oxygen demand (BOD) (0.21 mg/l - 2.11 mg/l), chemical oxygen demand (COD) (20.0 mg/l - 30.0 mg/l), phosphate (0.36 mg/l â€“ 1.54 mg/l), and nitrogen (0.47 mg/l â€“ 0.98 mg/l). During the day, the temperature ranged from 31.0 oC â€“ 32.0 oC, TSS (72 â€“ 93 mg/l), clarity (1.2 m - 4.5 m), pH (8.28 â€“ 8.40), DO (6.21 mg/l â€“ 6.82 mg/l), BOD (1.01 mg/l â€“ 2.62 mg/l), COD (20.0 mg/l â€“ 35.0 mg/l), phosphate (0.21 mg/l â€“ 1.22 mg/l), and nitrogen (0.48 mg/l â€“ 0.87 mg/l). Overall, the water quality was moderately polluted, with IP values ranging from 6.373 to 8.605 in the morning and from 5.553 to 7.946 in the afternoon.
