Abstract

The objective of this research were to know yield, protein content, free α-amino nitrogen, degree of hydrolysis, and amino acid of the result hydrolysis of ink protein squid (Loligo sp) with papain enzyme. The research used the method completely randomized design with two replications of the treatment factors, the difference in the concentration of the papain enzyme (0%, 1%, 2%, 3%, 4%, 5%, and 6%). The parameters of research were yield, protein content, free α-amino nitrogen, degree of hydrolysis, and amino acids. The results of research showed that differences in the concentration papain enzyme significant effect on the value of yield, protein content, free α-amino nitrogen, and degree of hydrolysis. Yield ranges from 78.05% to 88.61%, protein content from 28.90 mg/ml to 36.31 mg/ml, free α-amino nitrogen from 0.49 mg/ml to 10.99 mg/ml, the degree of hydrolysis from 0.016 to 0.345, and contains 14 kinds of amino acids of the 15 amino acids analyzed, histidine, arginine, threonine, valine, isoleucine, leucine, phenylalanine, lysine, glutamic acid, aspartic acid, serine, glycine, alanine, and tyrosine. The content of amino acid and degree of hydrolysis highest contained in the P2 treatment (papain enzyme concentration of 2%).

Abstract

The purposes of this research were to know characteristics of golden snail (Pomacea canaliculata) silage processed chemically and microbiologycal using lactid acid bacteria culture (LAB) 3B104. The research used the Factorial Randomized Block Designed with two factors of treatment and each was replicated three times. The factors were different of percentation formic acid (formic acid 2.5%, 3.0% and 3.5%), without and given lactid acid bacteria (LAB) culture 3B104. The parameters were chemical analysis (pH value, moisture content, ash content, protein content, fat content, carbohydrate, crude fiber) and microbiologycal analysis (Total Plate Count, Salmonella test, Escherischia coli test). The result of this research were different ration of percentage formic acid, without and given lactid acid bacteria culture (LAB) 3B104 had significant effect on pH value, moisture content, protein content, carbohydrate and crude fiber. The average value were pH value after fermentation (4.73-5.46), moisture content (77.98%-81.59%), ash content (2.25%-3.97%), protein content (10.88%-14.54%), fat content (0.45%-0.68%.), carbohydrate content (2.00%-3.70%.), crude fiber (0.56%-1.47%). The highest protein content (14.54%) was found in the treatment of formic acid 3.5% without given lactid acid bacteria culture (LAB) 3B104. The microbiologycal analysis showed total plate count (5.78 log CFU/gr-7.29 log CFU/gr), negative Salmonella and Escherischia coli.   Keyword: golden snail silage, formic acid, lactid acid bacteria (LAB)

Abstract

This community service activity was conducted with the Salted Fish Artisans Association in Kampung Siabang, Palembang, which is known as a household-scale salted fish processing center. The main problems faced by the partners include limited knowledge of hygienic practices, suboptimal technical skills in fish preservation, and low awareness of waste management from fish processing activities. This program aimed to improve the community’s knowledge, skills, and attitudes so that the salted fish processing practices become more hygienic, comply with quality standards, and adopt sustainable production principles. The implementation methods included an initial assessment using a pre-test questionnaire, counseling and technical training on hygienic salted fish processing in accordance with the Indonesian National Standard (SNI 8237:2023), hands-on practice of salting and drying techniques, and mentoring on the utilization of fish processing waste into value-added products. The program evaluation was carried out using post-test questionnaires, field observations, and in-depth interviews to assess changes in participants’ knowledge, skills, and attitudes. The results indicate a significant improvement in participants’ knowledge of hygienic practices and quality standards, with an average score increase of more than 20% between the pre-test and post-test. In addition, participants demonstrated improved skills in fish preservation techniques and increased awareness of environmentally friendly waste management through the utilization of fish by-products. The program also encouraged changes in production behavior toward more hygienic and sustainable practices. More broadly, this activity contributed to strengthening the capacity of household-scale salted fish processing enterprises, improving product quality, and creating opportunities to increase community income through more efficient processing and the utilization of economically valuable waste.
