Abstract

Canned fish industry production generates significant waste, which, if left untreated, can pollute the environment and have negative impacts. While solid waste from fisheries has been widely utilized, the utilization of liquid waste from fisheries remains uncommon. This research aims to analyze the chemical quality of liquid organic fertilizers and determine the best treatment between liquid waste from pelagic tuna canning and kepok banana peel extract. The research employed a laboratory experimental method with one treatment, which is different concentrations of liquid waste from fish canning and kepok banana peel extract, with four treatment levels and three replications: PO (700 mL liquid waste from fish canning), P1 (600 mL liquid waste from fish canning + 100 mL kepok banana peel extract), P2 (550 mL liquid waste from fish canning + 150 mL kepok banana peel extract), and P3 (500 mL liquid waste from fish canning + 200 mL kepok banana peel extract). The parameters observed were nitrogen (N) content, phosphorus (P) content, and potassium (K) content. The research data were analyzed using a completely randomized design (CRD). The data analysis results stated that the treatment levels of P0, P1, P2, and P3 had a significant effect on the quality of liquid organic fertilizer and were statistically significantly different on the levels of nitrogen, phosphorus, and potassium of liquid organic fertilizer products. The results indicate the appropriate formulation for liquid organic fertilizers nd the best chemical quality, which is treatment level P2 with a formulation of 550 mL. liquid waste from fish canning, 150 mL. kepok banana peel extract, 300 mL. coconut water, and 40 mL EM4, yielding nitrogen (N), phosphorus (P), and potassium (K) values of 3.18%, 5.47%, and 5.54%, respectively. These values meet the quality standard requirements for liquid organic fertilizers according to Minister of Agriculture Regulation number 70/Permentan/SR.140/10/2011, which is between 3-6%.Keywords:Fish wasteLiquid organic fertilizerNitrogenPhosphorusPotassium

Abstract

Fish is the primary source of animal protein for the Indonesian people, particularly in coastal areas such as Gorontalo Province. The freshness of fish is a key factor in ensuring food quality and safety. This study aimed to evaluate the freshness levels of fish for human consumption at Tenda Fishing Port in Gorontalo Regency based on organoleptic parameters and pH values. The samples consisted of four fish species: mackerel (Rastrelliger kanagurta), blue lolosi (Caesio caerulaurea), layang fish (Decapterus sp.), and yellow selar (Selaroides leptolepis), with four fish of each species collected using purposive sampling. Organoleptic testing was conducted by 25 semi-trained panelists in accordance with SNI 2729:2013, evaluating parameters such as appearance, gills, mucus, texture, and odor on a scale of 1-9. pH measurements were taken using pH indicator paper on the dorsal flesh. The results showed that all four fish species received organoleptic scores above 7, indicating that they were fresh and fit for consumption according to SNI 2729:2013 standards. pH measurements showed that mackerel and yellow mackerel had pH levels of 6,5-6,9, while blue lolosi and layang fish had pH levels of 6,2-6,5, which is consistent with the condition of fish in the rigor mortis phase. The correlation between high organoleptic scores and a pH range of 6,2-6,9 indicates that the fish for human consumption traded at Tenda Fishing Port were still fresh at the time of sampling. Consistent implementation of a cold chain system is necessary to maintain the quality of the fish until it reaches consumers.

Abstract

The waters of Tomini Bay have considerable potential for fish resources, including tuna. Fresh fish is very susceptible to damage and quality loss, so the commonly applied handling technique to maintain its freshness is to use low temperatures. This study aims to evaluate the quality of yellowfin tuna through organoleptic testing and TVB analysis. Yellowfin samples were taken from whole tuna that had previously undergone organoleptic testing, and then the meat samples were brought to the laboratory for TVB testing. Data analysis was done qualitatively, while laboratory testing was analyzed quantitatively using a non-factorial completely randomized design. The results of organoleptic physical testing of back, belly, and tail samples showed an average score of 8, which includes meat criteria such as brilliant color, good tissue strength, fresh aroma, and a dense, compact, and elastic texture. The results of the TVB test showed that the levels in the stomach and back were 5.80 mg N/100 g and 5.97 mg N/100 g, respectively, while in the tail, they were 5.70 mg N/100 g.

Abstract

This community service program aims to empower the coastal community of Huangobotu Village through an innovative approach to utilizing organic waste from the Inengo Fish Auction House (TPI) by converting it into nutrient-rich dry fertilizer. Organic waste generated from auction activities—such as fish residues, entrails, bones, skin, and scales—has not been optimally utilized. This condition has led to various environmental problems, including unpleasant odors, water pollution, and declining sanitation around the TPI area. Limited knowledge and inadequate waste-processing technology have further exacerbated the situation. Therefore, community empowerment initiatives are needed to transform this waste into more valuable products. Through a participatory approach, the implementing team engaged coastal residents, particularly youth groups (karang taruna), in technical training and mentoring for the production of dry fertilizer. The activities included raising awareness of proper waste management, demonstrating processing techniques, and applying simple methods using microbial activators. The results showed an increase in participants’ knowledge and skills in converting organic waste into useful, marketable fertilizer. Participants were able to independently apply basic processing techniques using microbial activators. Management and production levels improved by 70% and 75%, respectively, indicating the program’s effectiveness in enhancing awareness of proper waste handling. Beyond addressing environmental issues, the program also fostered greater understanding of circular economy practices within the community. Furthermore, the dry fertilizer innovation has encouraged the emergence of local business opportunities based on fishery waste. This waste-management model is expected to contribute to reducing coastal pollution and supporting environmentally friendly agricultural development in Gorontalo. The program effectively strengthened the community’s capacity in processing organic waste, and the dry fertilizer innovation has strong potential as a sustainable waste-management solution.

Abstract

Indonesian farmers still largely depend on chemical fertilizers, which in the long term can reduce soil quality and increase agricultural production costs. In Tunggulo Village, Tilongkabila District, Bone Bolango Regency, the use of organic waste such as fish waste and banana peels is still very limited and is generally only discarded. However, this waste contains nutrients that can be used as raw materials for making liquid organic fertilizer through a fermentation process. Therefore, community empowerment activities are needed to increase knowledge and skills in processing organic waste into environmentally friendly and economically valuable liquid fertilizer. This community service activity used a pre-test and post-test design to measure changes in participants' knowledge before and after training. The activity was carried out in three main stages, namely preparation, counseling, and training in the production of fermented liquid fertilizer based on fish waste and kepok banana peels. A total of 20 participants who were members of farmer groups were actively involved in the activities. The results of the activities showed an increase in participants' understanding after attending the counseling and training. The average pre-test score of 7.70% shows that participants' initial knowledge of fermented liquid fertilizer was still very low, while the post-test score increased to 81.83% after the activity was carried out. This increase shows that demonstration-based extension and training methods are effective in improving community knowledge and skills. Participants were also able to practice the process of making liquid fertilizer independently and showed interest in developing production on a household scale. This activity not only increased community awareness of organic waste management but also opened up opportunities for the development of sustainable agriculture-based village businesses.

Abstract

This study aimed to determine the effect of foam mat drying technique and maltodextrin concentration on the physicochemical characteristics of instant mangrove coffee made from Rhizophora stylosa fruit. The study employed a Completely Randomized Design with six level of different maltodextrin concentration (11%, 14%, 17%, 20%, 23%, 26%) and each with three replications. The parameters analysis included density, solubility, dissolution time and moisture content. The results showed that maltodextrin concentration affected the physicochemical properties of the product, as indicated by a bulk density of 0.39 g/mL, solubility of 68,05%, dissolution time of 58,44 seconds and moisture content of 2,56%. Higher maltodextrin concentration increased solubility and reduced dissolution time. The foam mat drying technique combined with appropriate maltodextrin addition has the potential to produce high-quality instant mangrove coffee. Keywords: foam mat drying, maltodextrin, instant coffee
