Abstract One form of service at fishing ports is mooring and achoring. This service affects the level of satisfaction. The higher the level of satisfaction, the fishermen’s expectations are fulfilled. Fishermen’s satisfaction is very important to improve performance in the development of a port. This study aims to determine the level of satisfaction of fishermen on anchoring services. …
Abstract Fishing tools used in indonesian are generally less enviromentally friendly and even incompatible with the conditions of the waters, so that many fishing gears damage the aquatic enviroment. The purpose this research is to assess the status of the enviromental friendlines the fishing gear used fishermen, and to set priorities for the development of fishing gear based on the status…
Abstract Measurement of customer satisfaction is an important element in providing better, more effective and more efficient service. The measure of the success of a service at a fishing port can be seen from the user satisfaction of harbourmaster with the service providers that have been provided. The purpose of researh were to know the satisfaction fishermen with the services provided an…
Abstract The selectivity of the fishing gear is defined as the ability of the fishing device to obtain specific fishing targets by type and size during the capture process and allow all unwanted by-catch catches to be passed unscathed (FAO, 1995). The purpose of this study was to find out the selectivity of the mesh size and the composition of the catch of drift gillnets in PPN Sungailiat.…
Abstract The financial aspect investigates the comparison between business expenses and revenues, whether the business will be guaranteed the necessary funds, whether the business is able to pay back the funds. He efficiency of the fishing business is determined by, among other things, measuring the productivity of the business with the Benefit-Cost Ratio. Benefit-Cost Ratio is the ratio b…
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…

The treatments given consisted of (A1) vacuum packaging and (A2) nonvacuum packaging. The quality parameters tested were organoleptic (appearance, aroma, taste and texture), Total Plate Count (TPC), and Total Volatile Base (TVB), with int…
ABSTRACT The purpose of this study was to evaluate the stability of pH, NPN and proximate silage of catfish waste (viscera) made with the addition of an inoculum and without an inoculum during storage. The experimental design used was the Paired samples test. The treatments made were 1) catfish viscera added 20% molasses, 2) catfish viscera added 10% molasses and 10% inoculum. The paramet…
ABSTRACT This study aims to determine the effect of fortification of nanocalcium of freshwater mussel shell flour plain bread. The treatment given was fortification of nano calcium of freshwater mussel on plain bread, consisting of R0 (0%), R1 (0.5%), R2 (1%), and R3 (1.5%). The analysis parameters observed were hedonic quality (appearance, aroma, taste, texture), Chemical Value (water, as…
ABSTRACT This study aimed to determine the effect of moringa leaf flour on the quality of macaroni catfish and increasing dietary fiber content. The research method was the experiment using a non-factorial Complete Randomized Design (CRD) with 4 levels of treatment, namely Mk0 (without moringa leaf flour), Mk1 (60 grams moringa leaf flour), Mk2 (90 grams moringa leaf flour), Mk3 (120 grams …
Abstract This research aims to obtain mussel shell nano minerals (Pilsbryoconcha sp) from ponds and rivers with the same treatment seen from physical, morphological and chemical parameters (mineral content). Physical analysis parameters observed were the calculation of yield and degree of whiteness of nano minerals. Morphological parameters observed were SEM and particle size. The same ex…
ABSTRACT Vanname shrimp are used frequently by people, whether whole vanname shrimp or without the skin and head. Unused skin and head waste have nutritional value so that they can still be reused. This study aims to determine the effect of different papain enzyme concentration on carotenoid extract of vanname shrimp skin and head waste. The research method is an experimental method with …
Abstract The study aimed to compare the using of DPPH and FRAP methods to assess the antioxidant activity of the golden snail egg extract (Pomaceae cannaliculata) and to determine the chemical composition contained in the golden snail eggs. The parameters tested were proximate analysis (the content of moisture, ash, protein, fat, and carbohydrate) (AOAC, 2005), extract yield (Karnila et al…
