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

Catch handling is a series of activities or treatments for fish without changing the basic structure and shape of the fish itself. Currently, the best handling is the application of a cold chain, which is to keep the fish cold (low temperature). The principle of proper handling of catches, namely, (3C+1Q) consists of cold, clean, careful, and quick. This study aimed to identify the catch of KM Sari Usaha 09 and to identify the organoleptic results of the catch on KM Sari Usaha 09 while on board and on land. The study was conducted from January to May 2023. Data collection methods were observation, documentation, and interviews. Data analysis was descriptive, and organoleptic tests were conducted on the main and by-catch fish. The handling of the catch on KM Sari Usaha 09 has an Organoleptic Test value when on board with a value of 9 for eyes (very fresh), 8.9 for gills (very fresh), 8.7 for meat (very fresh) and 8.8 for texture (very fresh), while the results on land are 6.6 for eyes (fresh), 6.8 for gills (fresh), 6.7 for meat (fresh) and 6.9 for texture (fresh).
