Eel can be used as raw material for fish meal because it is known to contain complete protein and amino acids. This study aims to determine the chemical composition of eel flour which is dried in the sun and oven. The research method used was an experiment by making eel flour dried in an oven and i…
ABSTRACT This research aimed to determine the type of lactic acid bacteria isolated from cincalok and determine the potential of bacteriocin from lactid acid bacteria as an antibacterial against Escherichia coli and Staphylococcus aureus. This research consisted of several steps, namely the manufacture of cincalok, isolation of lactic acid bacteria, isolation of bacteriocins and testing of…
ABSTRACT Vanname shrimp (Litopenaeus vannamei) is widely consumed by the community, on the other hand, the skin waste is underutilized. Shrimp shell has a potential use as a chitin product. Chitin can be isolated from shrimp shell by demineralization and then deproteination their shells. The demineralization process was carried out using citric acid. This study aimed to determine the effec…
ABSTRACT This study aims to determine the effect of adding different concentrations of chitosan solutions on the quality of facial moisturizing creams and to find out how much chitosan concentration is appropriate to add to the quality of facial moisturizing creams. The treatments given were different concentrations of chitosan, namely 1% (K1), 2% (K2), 3% (K3). The parameters used in this…
Abstract The viscera of catfish are a by-product in the processing of catfish that have not been utilized optimally. The viscera of catfish can be used as raw material for enzymes. The viscera of catfish are thought to contain protease enzymes. This study aimed to determine the activity of crude extract of protease enzymes from the viscera of catfish (P. hypophthalmus) at different pH. The…
ABSTRACT This study aims to find out the chemical and physical characteristics of gelatin from tilapia bone soaked using pineapple liquid extract. Pineapple fruit is known to contain citric acid that is quite high. The research method used in this study is an experimental method by pre-treatment (soaking) of fish bones in liquid extracts of pineapples using different times. G20 (soaking of…
ABSTRACT This study aims to determine the bioactive components of the sea grape (Caulerpa sp.) fraction qualitatively and to determine its antibacterial activity using the well method. In the extraction process, the solvent used is methanol with a ratio of sample: solvent 1:3(w/v). While solvent fraction is used there are 3 types, namely n-hexane, ethyl acetate and butanol with a ratio of …
ABSTRACT This study aims to determine the phytochemical components of bioactive compounds from the extract of Chlorella sp. and determine the antibacterial activity by the well method. There were 3 solvents to extract the Chlorella sp. namely methanol 70%, ethyl acetate 80%, and n-hexane 80% with a sample ratio of 1:2. The yield of Chlorella sp. extracts using methanol was 30.16%, ethyl ac…
Abstract This study aims to determine the characteristics of the organoleptic quality of biang fish (Setipinna sp) crackers with a different binder (sago and tapioca). An organoleptic assessment was carried out using a hedonic quality test with a treatment scale of 3 - 9, with 25 panelists being somewhat trained. The method used is experimental, namely conducting experiments on the process…
ABSTRACT Bivalve Anadara antiquata meat 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 from the bivalve with the addition of bromelin enzymes. It is hoped that it will provide the opportunity …
ABSTRAK Berunok sea cucumber is one of the typical marine biotas on Karimun Island that has not been utilized optimally, even though berunok sea cucumber has a high protein content, which is 60-70% in dry conditions and composed of specific amino acids. Therefore, sea cucumber has the potential as a raw material for protein hydrolysate. The process of hydrolysis in the manufacture of prote…
