Abstract

ABSTRACT               Fuel oil is the aspect that is most prepared before going to sea. In meeting the demand for fluctuating fuel oil demand, prediction is needed, so that it can predict the supply to meet the required amount. This study aims to predict the amount of fuel oil inventory each month by using fuzzy logic to meet the needs of fishing supplies.               The results showed that the prediction of fuel oil had increased compared to the supply of fuel oil in the previous year. The total supply of fuel oil in 2019 was 1866 tons, while the prediction of fuel oil inventories for 2020 was 1974 tons. The results of this fuel oil prediction were tested using MAPE (Mean Absolute Presentage Error) to get the accuracy value. The MAPE value obtained is 7.68% which is considered accurate and acceptable to determine the prediction results of fuel oil inventories.Keywords: Prediction of fuel oil inventory, fishing supplies, fuzzy logic

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
