This study used a Completely Randomized Design (CRD) with four treatments and three replications. The treatments performed were C0 (fortification of 0% Chlorella sp. powder/control); C1 (fortification of 1% Ch…
ABSTRACT Silage can be produced in two ways, namely chemically and biologically, followed by fermentation. Biological silage production is a fermentation process that utilizes certain microbes (lactic acid bacteria) by adding carbohydrate sources. The lack of carbohydrate content in fresh rebon shrimp can be added sago flour as a source of carbohydrates. The study aimed to determine the ef…
ABSTRACT The purpose of this study was to determine the proximate difference of instant shrimp paste shrimp paste (Acetes sp.) with the addition of different types of chili and to determine the level of consumer acceptance of making instant chili paste with different types of chili treatment. The method used is an experimental method by conducting experiments on consumer acceptance of the …
ABSTRACT Freshwater mussle clams is one of the mollusks that is originated in freshwater. The meat of the Freshwater mussle clams was widely consumed but its shells were still unused and so becoming as the waste. However, clam shells have the potential to become a chitin product. The production of chitin and chitosan in the deproteination process using chemical method can damage the qualit…
Abstract This study aims to evaluate the characteristics of the sensory quality, pH, ALT and BAL of cincalok made by the backslopping fermentation method with different inoculums. The method used was an experimental method with Racangan Acak Kelompok (RAK). The days (0,21,2,3) for category and the treatment given consisted of adding inoculums of 0% (C0), 10% (C10), 15% (C15), and 20% (C20)…
Abstract This study aimed to determine the effect of different KOH concentrations on the value of the deacetylation degree of chitosan from pensi shells (Corbicula moltkiana). The treatments given were differences in the KOH concentration of 40, 50 and 60%. The analysis parameters observed were the proximate test and FTIR. The results based on the standard of ash content, moisture content…
