Abstract

Silver rasbora fish is a fresh fish that is often found in the traditional market, but the product has decreased in quality during its distribution chain. Bekasam is a spontaneous fermented fish product by adding salt as microorganism selective material and rice as source of carbohydrates for expected microorganisms. Aims of this study were to innovate silver rasbora fish processing into bekasam and explore various kinds of processed rice as fermentation media. This study was used by a completely randomized design (CRD) with factor was processed rice, particulary uncooked rice, cooked rice, karak, and nasi aking that given to fish by 50% (w/w). Observations were made on fresh silver rasbora fish and bekasam to compare the quality of fermented products. The observed parameters included total lactic acid bacteria and organoleptic. The results showed that processed rice had significantly effect on total LAB toward bekasam (P 0.05). Total LAB of bekasam which were fermented by various kinds of processed rice which can classified as probiotic food between 8.12-8.75 log CFU / g. Likewise on the organoleptic properties had significant effect (P 0.05). The best product was obtained from the bekasam using karak as fermentation media. The bekasam had total LAB of 8.12 log CFU / g and also had organoleptic properties with a high level of preference compared to the others. Hopefully, this research can increases the added value of silver rasbora fish and better quality than fresh products.

Abstract

Blood clam (Anadara Granosa) is an important fishery commodity and is favored by the people around Kenjeran Beach, Surabaya. Blood clams can accumulate heavy metals such as Pb due to their living in sediments. Chitosan which comes from golden snail shells can bind Pb metal levels in blood clams. The purpose of this study was to determine the effect of concentration treatment and soaking time of gold snail shell chitosan on the reduction of blood clam Pb metal. Chitosan was produced by deproteination with 4% NaOH, demineralization with 1.25 N HCL, and deacetylization of chitin with 60% NaOH solution. The deacetylization degree of golden snail shell chitosan was 77.38%. The experimental design used was factorial CRD with two factors. The first factor was the concentration of chitosan (1%, 2% and 3%), while the second factor was the soaking time of the chitosan (90 minutes, 120 minutes, and 180 minutes). The data obtained were analyzed by ANOVA, if there were significant differences, then continued with the Duncan Test (DMRT). The best treatment produced was with a concentration of 3% chitosan and 180 minutes of soaking time for chitosan which reduced the Pb metal content of blood clams by 96.93%.
