Abstract

The use of fishery waste emphasizes a cyclical system in the production process, thereby creating clean production. Shrimp waste can pollute the environment around the factory so it needs to be utilized. One of the processing methods that can be done using shrimp heads is to make flavour. Islamic boarding schools and economic independence in an effort to develop Islamic boarding schools - are two things that cannot be separated. Training on fishery waste processing is one method to support economic independence in the form of entrepreneurship in Islamic boarding schools. Processing fishery product waste is an activity carried out in stages, sequentially, cleanly and hygienically, and meets quality requirements in order to convert fishery product waste into value-added products. The target of this community service activity is to establish a solid fishery waste processing business activity at the Nurul Huda Islamic Boarding School in Surabaya and be able to compete in the market continuously. The method used is an approach method that includes, among others, the Participatory method. The results that have been obtained from this activity are an increase in the knowledge of Islamic boarding school students about fishery waste, namely shrimp heads which are used as a flavouring/flavoring ingredient for safe cooking. The activity was attended by 43 students, with educational levels namely middle school and high school. Based on questionnaire data distributed, before the training was carried out, it was found that 93% of the students did not know that shrimp head waste could be used as a flavour. After the training, it was found that 94% of students were interested in making their own flavor production made from shrimp heads.

Highlight Research Experimental use of pre-treated pangasius skin as collagen raw material using different acetic acid immersion time Effects of immersion time on the yield of collagen from pangasius skin Effects of immersion time on the proximate content of collagen from pangasius skin Presenting SDS-Page profile of collagen from pangasius skin   Abstract Pangasius sp. production in Indonesia has reached 384,310 tons in 2019. One of the main waste in pangasius fillet industry is the skin, which reached to 6% of body mass. Fish skins are alternative for making collagen because it has no restrictions for certain religions and ethnicities. Collagen is a protein biomaterial which acts as the main component of connective tissue. Extracting collagen using organic acids such as acetic acid is the most common extraction method. Herein, we report the effects of different immersion time of acetic acid to collagen properties from pangasius skin. In this study, pangasius skin was treated using 10% alcohol with the ratio 1:10 (w/v) for defatting and 0.1M NaOH with the ratio 1:10 (w/v) for eliminating non-collagenous protein. The immersion of 0.5M acetic acid was carried out on pangasius skin with the ratio of 1:20 (w/v), for 24, 48, and 72h at temperature less than 15oC. The sample was salted-out for 24 hours with NaCl until the concentration reached 2.5M, then the sample was freeze-dried at -40oC. This study investigated that longer immersion time affected the properties of pangasius skin collagen. Different immersion time significantly affected the yield of collagen from pangasius skin (p<0.05). Pangasius skin has a potential to be used as collagen raw material, and 72h of immersion time (P3) is suggested to produce pangasius skin collagen with the highest yield and protein content (6.15 % and 9.26 %). Production of collagen from the fish skin will contribute to increase pangasius waste valorization in pharmaceutical industry.

Abstract

Highlight Research The optimal condition for production of water-soluble collagen from Alaska pollock fish skin was the pretreatment with 0.15 M acetic acid followed by hydro-extraction at 40oC with 150 rpm for two hours. Higher acetic acid concentration at a pretreatment step enhanced the higher yield of water-soluble collagen via hydro-extraction process. Hydro-extraction was an environmentally friendly method for converting Alaska pollock fish skin to water-soluble collagen. Alaska pollock fish skin could be used as an alternative source for collagen production. Abstract To date, there is no information on skin of Alaska Pollock (Theragra chalcogramma) being used as a source for collagen. In order to produce water-soluble collagen from the skin of Alaska Pollock, a process known as hydro-extraction is utilized. This technique does not need a long extraction time or a large amount of chemical reagent. The purpose of this study was to investigate the effect of acetic acid pretreatment on hydro-extraction of water-soluble collagen from Alaska Pollock skin. The skin samples were pretreated using acetic acid at different concentrations (0.01 M; 0.05 M; 0.1 M, 0.15 M) for two hours at chilling temperature. The pretreated skin samples were further processed to produce water-soluble collagen using the hydroxy-extraction method. The obtained collagen was analyzed for proximate compositions, yield, and amino acids compositions with high performance liquid chromatography. It was found that the proximate compositions of the collagen products, specifically the protein content (75%) and fat content (1%), met the requirements of the Indonesian National Standard (SNI 8076:2014). The collagen yield ranged from 2.6 to 3.13%. The predominate amino acids in collagen were glycine, arginine, proline, glutamic acid, serine, and alanine. Pretreatment of skin sample with 0.15 M acetic acid resulted in the highest yield of water-soluble collagen (3.13%) and protein content (91.13%). The skin of Alaska Pollock fish could be used as an alternative raw material to produce water-soluble collagen for medical, pharmacy or food processing applications.

Abstract

Islamic boarding schools are one of the traditional Islamic-based educational institutions that study Islamic religious sciences as their main study and apply them as daily charity. In terms of the curriculum, Islamic boarding schools no longer only provide religious education, but currently Islamic boarding schools provide additional subjects such as scouting, martial arts and entrepreneurship; both in the field of plantations, catering, sewing, cooperatives and others. Fishery product processing training is one of the methods to support economic independence in the form of entrepreneurship in Islamic boarding schools. Processing of fishery products is an activity that is carried out in stages, sequentially, cleanly and hygienically, and fulfills the quality requirements in order to convert raw fishery products into final products. The target of this community service activity is to form a fishery product processing business activity at the Nurul Huda Islamic Boarding School in Surabaya that is solid and able to compete in the market continuously so as to make the Islamic boarding school an independent institution and have a sustainable business. The method used is the method of approach that is carried out, among others, namely the Participatory method. The results that have been obtained from this activity are the increased knowledge of Islamic boarding school students on the importance of sanitation and handling of fishery products (processed products in the form of fish nuggets and dragon feet). The activity was attended by 40 students, with education levels, namely junior high and high school. As many as 90% of the participants in the Fishery Products Handling Technique training wanted further activities to increase their knowledge in the field of handling fishery products.

Abstract

Fried fish balls (basreng) are a type of product modified through two processing processes, namely boiling and frying. Frying process can have an impact on health due to high oil absorption resulting in high fat content values. This can be overcome by providing low-fat ingredients, namely lindur fruit flour. Lindur fruit flour tends to have a high starch content, namely in the hydroxyl group. The presence of hydroxyl groups is able to bind the water content of the dough, thereby reducing water evaporation which can form product pores when frying. Binding water to the dough reduces excessive oil absorption in the product. This study was conducted to determine the effect of lindur flour (Bruguiera gymnorrhiza) on chemical characteristic and acceptability of patin (Pangasius sp.). The treatment used in this study was the addition of 0%, 5%, 10%, dan 15% lindur fruit flour in the fish basreng. The parameters in this study are proximate content test and organoleptic test. The results showed that the addition of lindur fruit flour (Bruguiera gymnorrhiza) made a significant difference in the resulting basreng products. Patin basreng was the addition of 5% lindur fruit flour (Bruguiera gymnorrhiza) is the best patin basreng by the nutrient content and dan is the most preferred treatment by the panelis. Patin basreng was the addition of 5% lindur fruit flour (Bruguiera gymnorrhiza) has nutritional component 44,91% water; 1,78% ash; 8,27% protein; 8,11% fat; and 36,92% carbohydrate.
