Abstract

This study aims to analyze the effectiveness of coating time with belimbing wuluh (averrhoa blimbi) extract in reducing the heavy metal mercury (Hg) levels in Mozambique tilapia (O.mossambicus). This research employed a Completely Randomized Design (CRD) method where the data were analyzed using variance analysis (ANOVA) and further tested by Duncan's multiple range test. The study was conducted using an experimental approach with two replications at three different locations: downstream (Bolangitang River), midstream (Sonuo Village), and upstream (Ollot Village). The treatments involved different coating times with averrhoa blimbi extract. The treatment levels consisted of four control levels: 5 minutes, 10 minutes, and 15 minutes. The research results demonstrated that a 15-minute coating time with averrhoa blimbi extract significantly reduced mercury levels in Mozambique tilapia in the downstream area of the Bolangitang River, with the highest reduction percentage reaching 63%. Meanwhile, the lowest reduction percentage was observed in the midstream area (Sonuo Village), with a 10-minute coating time resulting in a reduction percentage of 20.01%. Thus, the coating time of averrhoa blimbi extract was 50% effective in reducing heavy metal mercury (Hg) levels. This study contributes significantly to understanding the potential use of natural materials in addressing heavy metal pollution in freshwater ecosystems. It also highlights the relevance of utilizing local materials such as averrhoa blimbi as an alternative in conservation efforts and the protection of the environment and fisheries resources.

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

Mangroves are coastal ecosystems, especially in tropical areas including Tomini Bay, Gorontalo Province. Mangrove ecosystems not only function as coastal abrasion barriers, natural protection from ocean waves, but also as plants that are beneficial to human life, especially for coastal communities. . This study aimed to identify and analyze the structure of mangrove communities on the coast of Tomini Bay, Boalemo Regency, Gorontalo Province. Data collection was carried out using the line transect method at four observation stations for the seedling and sapling categories., then analyzed to determine the absolute density, absolute frequency, and dominance of species. Mangroves found in Tomini Bay, Boalemo Regency from the four stations consist of A. marina, B. gymnorhiza, B. parviflora, C. decandra, C. tagal, R. apiculata, R. mucronata, R. stylosa, S. alba, S. caseolaris, X. moluccensis. In the seedling category, the C. tagal mangrove species at station 2 (Dulangeya Village) showed the highest value in Boalemo Regency, with an absolute density of 56 ind/m², an absolute frequency of 0.48, and a relative dominance of 87.5%. On the other hand, the B. gymnorhiza species recorded the lowest value compared to all observation stations in Boalemo Regency, with an absolute density of only 1 ind/m², an absolute frequency of 0.05, and a relative dominance of 1.56%. The C. tagal mangrove sapling category at station 2 (Dulangeya Village) had the highest absolute density, absolute frequency, and relative dominance in Boalemo Regency, at 8.36 ind/m2 and 0.71 and 73.85, respectively. R. apiculata had the lowest density of all stations in Boalemo Regency, at 0.04 ind/m2 and 0.05 and 0.35, respectively

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
