Abstract

This study focuses on assessing the coastal conditions in Jambi Province both physicochemical and biological parameters. This combination of assessments previously still had limited understanding. Retrieval of physical parameter data using a multi-parameter water quality analyzer, chemical data using the APHA method and spectrophotometer, and chlorophyll-a data using the Copernicus Marine Environment Monitoring Service (CMEMS). The results, with adjustments to national quality standards and pollution index measurements, showed that the five research stations on the east coast of Jambi experienced light to moderate pollution with a score range of 1.252-5.831. Pollution is in the form of nutrients, especially nitrate. However, the trophic index of the coast is classified as oligotrophic, which ranges between 0.689278 - 0.7599 mg/m3. Otherwise, the high nutrient values are TOM and TN, which have a significant correlation, besides the correlation with DO and pH. Measurements of TN and TP in the water column and sediment have also been carried out, where the water column TN concentration is about 5 times higher than the sediment TN and the water column TP concentration is 7 times lower than the sediment TP. The results of this study will contribute to a better understanding of coastal ecosystem health and its significance for the management of the coastal environment in Jambi as a fisheries catchment area.

Abstract

Fish is a fishery product that has high nutritional value. Fish can be processed into various processed products. Processed fish products generally have the characteristic of not lasting long when stored at room temperature so that in the food processing, additives are added. Hazardous food additives that are often used in processed fish products are formalin. Formalin is a preservative that can cross-link with protein so as to prevent damage to product and can extend its shelf life. This study aims to determine the formalin content in processed fish products, namely fish meatballs and salted fish in traditional markets in Jambi City. The research method used laboratory experiments with 4 treatments and 3 replications. The results showed that the samples of fish meatballs and salted fish as a whole were positive for formalin. This shows that the food safety of processed products in traditional markets in Jambi is still low. The knowledge and awareness of the fisheries processing community about hazardous food additives is still low.
