Abstract

Purpose: The purpose of this study was to determine the effect of adding surimi wastewater on the increase of nitrogen, phosphorus, and potassium content in Gracilaria sp. liquid organic fertilizer. Research Methodology: This research used an experimental method with a completely randomized design consisting of four treatments (0%, 80%, 90%, and 100% surimi wastewater) and five replications. Macronutrient content (nitrogen, phosphorus, and potassium) in the liquid fertilizer was measured after 14 days of fermentation to evaluate the effect of the treatments. Results: The results showed that the addition of surimi wastewater significantly increased the levels of nitrogen, phosphorus, and potassium in Gracilaria sp. liquid organic fertilizer (P < 0.05). The highest nutrient content was observed in treatments with higher concentrations of surimi wastewater, indicating a positive correlation between wastewater addition and nutrient enrichment. Conclusion: Surimi wastewater can be effectively utilized as an additive in Gracilaria sp. liquid organic fertilizer production to enhance its macronutrient composition. This approach demonstrates potential for sustainable fertilizer development using seafood processing by-products. Limitations: The study was limited by a relatively small sample size and a short observation period, which may restrict the generalizability of the findings. Longer-term studies and larger-scale trials are needed for broader validation. Contribution: This study provides insights into the sustainable utilization of surimi wastewater as a cost-effective nutrient source in liquid organic fertilizers, offering potential benefits for eco-friendly agricultural practices and waste management strategies.

Abstract

Abstract Fish skin is rich in collagen (80%-90%). However, catfish (Pangasius sp.) skin has a high lipid content, which can reduce the quality of collagen. Therefore, treatment is needed to remove the lipid using ultrasonic assisted extraction (UAE) with ethanol. Hence, the aim of the present study was to remove lipid content from catfish skin as a raw material for collagen by using UAE with different concentrations of ethanol (25, 50, and 75%). The research was conducted in three stages: removing impurities, collagen extraction, and characterization of collagen. The result exhibited that UAE-ethanol treatment was capable of removing up to 85.6% of lipid content, and the produced collagen had the potential to be utilized as an alternative source of collagen based on its properties. Highlight Research Ethanol could be used as extractor of lipid from catfish skin of Pangasius Ultrasonic assisted extraction could increase efficiency of lipid extraction from catfish skin. Fish skin of Pangasius sp. has a potential source for collagen. Collagen from skin of Pangasius sp. has a good characteristic with high protein content.

Abstract

Increasing cultivation activities and intensifying ponds has the potential to give rise to problems, namely increasing cases of disease in grouper fish, namely Zeylanicobdella, causing mass deaths of up to 100%. This study aims to analyze the histopathological picture of grouper skin infested with Zeylanicobdella arugamensis after administering papaya leaf juice with different soaking times and concentrations of papaya leaf juice. The method used was experimental Completely Randomized Design (CRD) with a factorial pattern consisting of two factors, namely factor A, different concentrations of papaya leaf juice consisting of 0% (A1), 0.1% (A2), 0.3% (A3) , and 0.5% (A4), as well as factor B for grouper rearing time consisting of the 0th minute (B1), 60th minute (B2), and 120th minute (B3) with five repetitions. The results of the study showed that the soaking time of papaya leaf juice in grouper fish had an effect on reducing the degree of Zeylanicobdella infestation, there were changes in the histopathological picture and water quality values before and after soaking. Treatments A2, A3, and A4 experienced a decrease in the degree of ectoparasite infestation at 60 and 120 minutes of immersion. The histopathological scoring values for treatments A2, A3, and A4 decreased at 60 and 120 minutes of maintenance. The best treatment combination was 0, 3% and soaking time at 120 minutes. In conclusion, giving papaya leaf juice with a soaking time of 120 minutes with a concentration of 0.3% can reduce the degree of infestation and the histopathological scoring value of Zeylanicobdella in grouper fish.

Abstract

Mayonnaise is a semi-solid emulsion processed product that has a very high fat content because the basic ingredients consist of vegetable oil (70-80%) and egg yolk (15-20%). Generally, mayonnaise has a high fat and calorie content. High fat content if consumed excessively will cause various diseases such as cholesterol, coronary heart disease and the risk of obesity. The use of lemuru fish oil as a substitute for mayonnaise is still rarely done. The protein content in lemuru fish is high enough that can be used as a source of protein. In addition to protein, lemuru fish oil is also enriched by the PUFA content of DHA of 30.10%. The aim of this research was to determine the quality of mayonnaise based on the organoleptic value and stability of the lemuru fish oil mayonnaise emulsion after a shelf life test. Proximate fat analysis using the Soxhlet method, protein analysis using the Kjeldahl method, ash analysis using a furnace, crude fiber analysis using the gravimetric method, water content analysis by evaporating the water in the material using an oven, carbohydrate analysis using the differential method. Shelf life test using the Accelerated Shelf Life Test method. Organoleptic testing uses a hedonic scale (1-5), with a total of 30 panelists. Emulsion stability test using a centrifuge by calculating the volume of oil separated. This study used a factorial randomized block design with two factors, namely temperature (5, 25, 35°C) and time (7, 14, 21 days). Mayonnaise proximate results from all parameters have met SNI except for fat and calorie parameters which tend to be lower than SNI standards. The ANOVA test results showed significant differences in organoleptic color and aroma, but it did not show significant differences in organoleptic texture and mold. The best organoleptic results at one-week storage. The emulsion stability results showed significant differences due to temperature and storage time factors.The best emulsion stability results at one week storage at 5, 25 and 35°C with a value of 100%.

Abstract

Lemuru fish (Sardinella lemuru) is rich in omega-3 so it is widely used as raw material for fisheries production such as fish canning which produces by-products in the form of crude fish oil which needs to be purified by adding adsorbents so that it becomes pure fish oil. The adsorbent that can be used in the purification of fish oil is activated charcoal. Fish oil can be used as raw material for making added value products such as margarine. The aim of this study is to analyse the characteristics of margarine as a value-added product made from fish oil. Research shows that purification with activated charcoal produces fish oil with %FFA and PV that are in accordance with IFOS. Fish oil margarine in this study showed organoleptic value of colour 7.4 and aroma 7.07, emulsion stability 100%, %FFA content 0.28 ± 0.08, PV 1.6 ± 0.173, and higher 0.39% EPA and 2.58% DHA content compared to commercial margarine. In previous study showed margarin from sardine fish oil contains 19.5% EPA and 10.5% DHA which is also not found in commercial margarine from palm oil. The difference in EPA and DHA content between this study and previous study may be due to the fact that the fish oil in this study was obtained from by-products of canning processing with high temperatures which may cause a decrease in fatty acid levels due to protein denaturation.

Abstract

This study aims to determine the effect of caulerpa habitat location on the content of active compounds and their activities as antibacterial. This research is experimental and data analysis with ANOVA. Samples come from three different locations of CBL, CBB, and CL as well as two different solvents, ethanol and n-hexane. According to research, the highest antioxidant activity produced by n-hexane CBL is 73.48%. The highest value of phenol gives n-hexane CBB at 292,867 mg/mL. The highest total flavonoids are 11.91 mg/ml produced by CBB ethanol. The total chlorophyll is between 0.25–0.87 mg/mL, while the total carotenoid is between 1.40–4.11 µ mol/L. The clear zone is formed in only 2 samples with S-test bacteria. It has 0.5 mm aureus n-hexane CBB and 1.5 mm n-hexane CL. This zone is clearly classified as very small, this can be due to the small content of the extract in the test sample. Active compounds found under the GCMS test are alkanes, alkenes, alcohols, and other fatty acids. These active compounds are a group of potentially antioxidant and antibacterial agents. It can be inferred that habitat location affects active compounds and CBB has greater potential as a source of natural materials than other samples.

Abstract

This study aims to analyze the effect of giving a combination of vitamins C and E as Artemia sp. supplementation on the level of stress resistance of Banggai cardinalfish. The research method used a completely randomized design. The treatments used were a combination of vitamins C and E in supplementation of Artemia sp. as feed: A (vitamin C 57.50 mg/L + vitamin E 28.75 mg/L), B (vitamin C 115 mg/L + vitamin E 57.50 mg/L), C (vitamin C 230 mg/L + vitamin E 115 mg/L), D (vitamin C 460 mg/L + vitamin E 230 mg/L), and E (vitamin C 920 mg/L + vitamin E 460 mg/L), each treatment was repeated 4 times. The main parameters observed were the level of stress resistance (frequency of pectoral fin movement, frequency of operculum movement, frequency of mouth movement) and blood glucose. Data were analyzed using analysis of variance (ANOVA) and further tests were carried out to determine the differences between treatments. The results showed that supplementation of vitamin C and E in Artemia sp. with different dose combinations had a significant effect (P < 0.05) on the frequency of pectoral fin movements, operculum movement frequency, and mouth movement frequency after hypoxia treatment at the 2nd, 4th and 8th hours and blood glucose levels after hypoxia treatment. The best stress resistance level during the study was in treatment C (vitamin C 230 mg/L + vitamin E 115 mg/L), while the lowest was in treatment A (vitamin C 57.50 mg/L + vitamin E 28 mg/L).

Abstract

The purpose of this study was to find a correlation between density and water quality with glucose and cortisol levels in Cantang grouper (Epinephelus fuscoguttatus x Epinephelus lanceolatus) reared in ponds as an indicator of stress. This study uses a time series sampling method in its implementation. There were 10 Cantang grouper samples taken in this study per pond with sizes ranging from 20-30 cm. Fish samples were taken from 3 different ponds so that a total of 30 cantang grouper samples were found, while 1.5 L of water samples were taken from each pond. The results of measuring glucose levels showed that the highest average glucose levels in fish blood were obtained in pond number 6 (51.22 ± 14.9 mg dl-1) while the lowest was in pool number 5 (40.95 ± 15.2 mg dl-1). Similar to glucose levels, the results of blood cortisol measurements showed that the highest average cortisol levels in fish blood were obtained in pond number 6 (116.45 ± 5.49 ng ml-1) while the lowest was in pool number 5 (112.64 ± 4.55 ng ml-1). Based on the results of the regression analysis between the variables of water quality factors and stocking density on glucose levels (Figure 1), an R-value of 0.729 is obtained, which means that there is a 72.9% relationship between the variables of water quality factors and stocking density on glucose (moderate relationship). While the results of the regression analysis between the variables of water quality factors and stocking density on cortisol levels (Figure 2), an R-value of 0.722 was obtained, which means that there is a 72.2% relationship between the variables of water quality factors and stocking density on cortisol (moderate relationship). According to this research study, water quality factors that had a significant effect (p>0.05) on glucose levels in Cantang grouper were Temperature, DO, Salinity and Ammonia.
