Abstract

ABSTRACTThis study aims to determine the yield of each fraction of sea grape extract (Caulerpa lentillifera) with solvents based on the level of polarity.The research method used was an experiment by conducting a series of experiments by extracting and fractionatingC. lentillifera sea grapes with solvents of different polarity, namely n-hexane, ethyl acetate and butanol.The parameter test was yield value of the extract fraction in C. lentillifera.. The result showed that the highest yield was obtained from non polar solvent in hexane fraction 0.42%, followed by semi polar solventin ethyl acetate fraction 0.33% and non polar solvent in butanol fraction 0.31%. Therefore, the yield of sea grape is more optimal extracted using non polar solvent n hexane fraction than semi polar etyl ecetate and polar solvent butanol fraction.Keywords: Sea grape (Caulerpa lentillifera), Extraction, Fractionated, Yield

Abstract

ABSTRAKThis research was conducted in September 2021 at the Bungus Ocean Fishing Port, West Sumatra Province. This study aims to determine the type of catch, analyze the technical and financial aspects of the fishing business and determine the feasibility of the fishing gear on the boat lift net. The method used in this research is the survey method. From the results of this study, the main catches (HTU) were squid, scad, mackerel, and anchovies while the by-catch (HTS) were skipjack and tuna. The financial analysis and profitability of the lift-net fishing business shows that the capture fisheries business with this tool is financially profitable and has a short payback period. The analysis of the feasibility of fishing business by fishermen for a full year is feasible to be developed, because the total revenue is greater than the total revenue is greater than the total cost and the value of Revenue Cost Ratio > 1. This can be interpreted that fishermen are classified as profitable. Keyword: Lift net, catch, financial analysis and feasibility
