Abstract

Seafood provides essential nutrients beneficial for human health; however, it is highly vulnerable to harmful bacterial infections that pose significant public health risks. This research seeks to assess the prevalence of five categories of seafood obtained from various traditional fish markets in Bali Province. A total of 108 tuna samples, 78 pelagic fish samples, 37 cephalopod samples, 14 sardine samples, and 53 demersal fish samples were collected from various traditional markets in Bali Province. This research evaluated the prevalence of E. coli, coliforms, Salmonella, V. cholerae, and V. parahaemolyticus. The study revealed that the highest prevalence of E. coli, coliform, and V. parahaemolyticus contamination in tuna samples was 95 (87%), 95 (87%), and 103 (95%), respectively. The study indicated that E. coli and coliforms were present in 73 of the 78 pelagic fish samples, representing 93% contamination. Sardine samples exhibited the lowest prevalence of bacteria. All seafood samples, however, tested negative for Salmonella and V. cholera. PCR products from E. coli and V. parahaemolyticus isolates were effectively amplified for the target genes utilized in this study. Local seafood markets should adopt appropriate handling and storage practices to enhance seafood quality. This study emphasizes the significant presence of E. coli, coliforms, and V. parahaemolyticus in seafood, along with the potential health risks posed by specific strains and their antibiotic resistance.

Abstract

Problems related to landfills of plastic packaging waste are a source of environmental pollution. This research provides innovation in utilizing biodegradable plastic from cassava and leri peel starch with the addition of chitosan. This study aimed to analyze the results of the synthesis and characterization of chitosan membranes with a combination of cassava and leri peel starch and determine the biodegradation time of biodegradable plastic in EM-4 bioactivation. This study characterized biodegradable plastic membranes using test parameters, namely the SEM, FTIR, Swelling, and tensile strength tests. The biodegradation test was carried out by immersing biodegradable plastic membranes in an EM-4 bioactator for 7 days. Based on the results obtained from the characterization of biodegradable plastic membranes, namely the swelling test with concentrations of 5:3, 7:3, and 9:3, with yield values ​​of 62.9921%, 69.8902%, and 71.4286%. The SEM test obtained the best results at a concentration of 7:3. FTIR test on biodegradable plastic membranes containing hydroxyl (O-H) and carbonyl (C-O) groups. The tensile test obtained optimum results at the concentration of biodegradable plastic membranes, namely 9:3. As for the biodegradation test that has been carried out, the start time for degradation is 3 days.
