Abstract

 ABSTRACT            Bivalve Anadara antiquatameat has a potential use as a raw material for producing protein hydrolyzate because it contains quite high protein.However, it has not been utilized optimally in its processing, so that it is necessary to do research on producing protein hydrolyzate fromthe bivalve with the addition of bromelin enzymes. It is hoped that it will provide the opportunity as an alternative source of animale protein and will increase the added value of the bivalve. The purpose of this study was to produce protein hydrolyzate from the bivalve using the bromelin enzyme. The method use was experimental composed as a non-factorial completely randomized design. It was contained 4 treatment levels of different enzyme concentrations(0%, 3%, 6%, and 9%). Parameters observed were the yield and the degree of hydrolysis. The addition of Bromelin enzyme at different concentrations has a very significant effect on the yield value and the hydrolysis degree. The addition of 9% enzyme was the best treatment. The best yield value on the hydrolyzate protein of bivalve after freeze drying15.62% and the value of the degree of hydrolysis was 14.68% and was the optimum condition for hydrolyzing bivalve meat.Keywords: Bivalve, Bromelin Enzyme, HydrolyzateProtein

Abstract

The size of the fly population at the time of Salted Catfish production (SC) is one of theimportant problems that will have an impact on the health and deterioration of fish quality, as well ashaving an impact on socio-economic conditions. Flies are mechanical vectors for the transmission ofdiseases carried through microorganisms Staphylococcus aureus (S.aureus). To deal with this problemproducers use chemical insecticides which are sometimes used at inappropriate dosages, so that they willadversely affect human health and the environment. therefore it is used by Fragrant Pandan Leaves(FPL) which have chemicals as poisons for vectors and safe for humans. This study aims to identify thecontamination of S.aureus bacteria in SC from Penyasawan Village, to analyze the effectiveness of FPLextracts in reducing the number of flies in the process of drying the SC on product acceptance. Usingexperimental research methods, with RAL, it was carried out at the UPTD laboratory for fish diseasesand the water quality of the Kampar Regency Fisheries Service. Data were analyzed using the One-WayANOVA statistical test. The results showed that, for the most part Salted Catfish from PenyasawanVillage is identified contamination of Staphylococcus aureus bacteria. Pandan Wangi Leaf Extract caneffectively reduce the density of flies that perch during drying of Salted Catfish with the highestconcentration having the greatest resistance to the flies of flies. Salted Catfish soaked in Pandan Wangileaves are in demand by consumers
