Abstract

It is feared that the high level of human activity in the coastal areas of Dumai City and Bengkalis City will have a polluting impact on water quality conditions. Therefore, to preserve coastal and marine functions, it is necessary to manage the quality and control of sea water pollution for present and future purposes as well as ecological balance. This research aims to determine the water quality of Dumai City and Bengkalis City, focusing on the concentration of several physical and chemical water parameters listed in the sea water quality standards for marine biota. Water quality sampling was carried out in May-August 2023 at 12 research stations, then the results were compared with sea water quality standards for marine biota. The research results show that the parameters that still comply with sea water quality standards for marine biota based on the Decree of the Minister of the Environment No. 51 of 2004 are temperatures in the range of 28.7-30.8˚C and an average value of 29.45˚C., pH ranged from 6.4–7.2, with an average value of 6.9 and dissolved oxygen (DO) ranged from 5.0 – 5.9 mg/l, with an average of 5.34 mg/l. Meanwhile, the parameters that do not comply with quality standards are low brightness ranging from 0.40 m-0.58 m with an average brightness of 0.47 m and salinity ranging between 22-28 ppt, with an average salinity of 24 ppt

Abstract

Work productivity can decrease if a worker suffers from musculoskeletal disorders (MSDs). Ergonomic review study so that MSDs can be prevented or minimized. The study examined MSDs in ABK operating purse seine fishing gear. The method used in this study is the WERA (Workplace Ergonomic Risk Assessment) method. The results of the study obtained the risk level in 3 work positions with a medium level and one work position at a low level. The score at the medium level is between 39 and 42 scores, while the score for the low level itself is at 27. The highest score is in the stern work position with a value of 42 and the lowest score occurs in the work position handling the catch with a value of 27.

Abstract

Keselamatan dan Kesehatan Kerja (K3) merupakan aspek fundamental dalam operasional kapal perikanan karena tingginya risiko kecelakaan kerja di lingkungan laut. Tingkat kepatuhan terhadap penyediaan dan penggunaan alat keselamatan kerja menjadi faktor penentu dalam pencegahan kecelakaan bagi awak kapal. Penelitian ini bertujuan untuk menganalisis kepatuhan penerapan K3 pada kapal longline berdasarkan regulasi nasional dan standar keselamatan internasional. Penelitian menggunakan metode deskriptif dengan pendekatan observasional melalui pemeriksaan langsung terhadap ketersediaan alat pelindung diri, fasilitas kesehatan kerja, serta peralatan keselamatan kapal. Acuan penilaian meliputi Undang-Undang Nomor 1 Tahun 1970 tentang Keselamatan Kerja, Undang-Undang Nomor 36 Tahun 2009 tentang Kesehatan, Peraturan Menteri Tenaga Kerja dan Transmigrasi Nomor 8 Tahun 2010, serta ketentuan SOLAS 1974. Hasil penelitian menunjukkan bahwa sebagian besar alat keselamatan kerja telah tersedia dan digunakan, namun masih ditemukan beberapa ketidaksesuaian terhadap standar yang berlaku, terutama pada aspek perlindungan kepala, kelengkapan kotak Pertolongan Pertama Pada Kecelakaan (P3K), serta ketersediaan rakit penolong. Temuan ini menunjukkan perlunya peningkatan pengawasan, pemenuhan standar keselamatan, dan penguatan budaya K3 guna meminimalkan risiko kecelakaan kerja di kapal perikanan. Occupational Health and Safety (OHS) is a critical aspect of fishing vessel operations due to the high risk of workplace accidents in the maritime environment. Compliance with the provision and use of safety equipment plays a key role in preventing accidents among crew members. This study aims to evaluate OHS compliance on longline fishing vessels based on national regulations and international safety standards. A descriptive research method with an observational approach was applied through direct inspection of personal protective equipment, occupational health facilities, and onboard safety equipment. The assessment criteria were based on Law Number 1 of 1970 on Occupational Safety, Law Number 36 of 2009 on Health, Regulation of the Minister of Manpower and Transmigration Number 8 of 2010, and the Safety of Life at Sea (SOLAS) Convention 1974. The results indicate that most safety equipment is available and implemented; however, several non-compliances with established standards were identified, particularly regarding head protection, first aid kit completeness, and the availability of liferafts. These findings highlight the need for improved supervision, full compliance with safety standards, and the strengthening of OHS culture to reduce occupational accident risks on fishing vessels.

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.
