Abstract

Based on exports data mackerel (Scomber sombrus) in 2023 approximately 2,702 tons, while by-products had produced around 60%. This creates serious problems with its disposal. Fish by-products can be processed into value-added products, one of which is fish protein hydrolysates. The purpose of the study was to determine the molecular weight of the SDS-PAGE (Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis) method and the antioxidant activity DPPH assay (2,2-diphenyl-1-picrylhydrazil) hydrolysate of mackerel viscera protein. The results showed a molecular weight in the range of 12 – 16 kDa. Antioxidant activity was shown by an inhibition percentage value of  50.117 ± 0.4793 % with an antioxidant capacity of 0.9141 ± 0.0606 mmol TE/g of Trolox equivalent samples. Based on antioxidant activity, mackerel viscera protein hydrolysate has the potential to be a natural source of antioxidants.

Abstract

Tuna is one of the most important fishery commodities for export. Commodities that can be exported must first have certificates of feasibility for class A and class B fish processing. Class A fish processing feasibility certificates are used for export at the international level while those in class B are used for exports at the Asian level. The initial certifications that need to be met are Good Manufacturing Practices (GMP) and Sanitation Standard Operation Procedure (SSOP). The aims of this study was to determine the profile of the Fish Processing Unit (UPI) with processing feasibility certification with A and B qualifications for tuna commodities through the application of Good Manufacturing Practices (GMP) and Sanitation Standard Operation Procedure (SSOP) and deviations that occur in Fish Processing Units (UPI). The method used in this study is a quantitative descriptive observational design. The results show that many of the results of supervision of feasibility certificates for processing medium-large scale fish processing units in East Java still have a B qualification. From the results that tuna is still widely exported at the Asian level.

Abstract

Probolinggo Regency has a very large fisheries sector potential consisting of   the   capture   fisheries   subsector,   the   aquaculture subsector (ponds, ponds and cages) and the fisheries processing subsector which has the potential to be developed, with total production in the aquaculture sector of 8,084,060 kg/Ha. One of the commodities that is widely cultivated in ponds in Probolinggo Regency is vaname shrimp, both in monoculture and polyculture, with total production in 2017 for vaname shrimp amounting to 2,100.50 tons. Most of the shrimp cultivation production is obtained from intensive pond cultivation which covers an area of 500 hectares and this pond area contributes 90 percent of the total shrimp production in Probolinggo Regency. Problems that have long occurred among shrimp farmers in ponds include: 1) Low knowledge of cultivation technology, 2) Failure to harvest, if possible the harvest has not been able to meet the target and is experiencing a decline, 3) Shrimp that are kept are easily attacked by disease and 4) decline water quality during maintenance. The aim of this community service is to increase the yield of vaname shrimp for a group of beginner farmers, Pajurangan Village,   Gending   District,   Probolinggo   Regency. The solution applied to solve   this problem is the application of immunostimulants from Zoothamnium sp protein. for the purpose of increasing the shrimp's body defenses and using probiotic EM-4 to improve and maintain water quality and help the absorption of food essences in the shrimp' body. To achieve this goal, the implementation of this community service activity consists of three stages, namely: (a) the socialization stage of cultivation methods with immunostimulants and probiotics, (b) the immunization and probiotic propagation training stage and (c) the application stage of cultivation methods with immunostimulants and probiotics in the pond.

Abstract

This study aims to determine the influence and determination of the optimal dose of the addition of brown algae extract on the growth performance and immunity of god fish seeds. The research was conducted in March - May 2024, at the Aquaculture Lab Building 4, FPIK Unpad, and the production of brown algae extract was carried out at the Aquaculture Lab Building 2, FPIK Unpad. This study used a complete randomized design (RAL) experimental method with four treatments and four replicates. The treatments given were (A) 100% commercial feed (control), (B) commercial feed added with brown algae extract at a dose of 10gr/kg, (C) commercial feed added with brown algae extract at a dose of 15 g/kg, and (D) commercial feed added with brown algae extract at a dose of 20 g/kg. The maintenance of fish fry is carried out for 40 days, with feeding three times a day. The observed parameters included absolute length growth parameters (L), absolute weight (W), specific growth rate (SGR), feed conversion ratio (FCR), feed utilization efficiency (EPP), and survival rate (SR) which were analyzed using ANOVA (Analysis of Varience) with a confidence level of 95%, if there is a significant difference, followed by the Duncan test. Water quality data was analyzed descriptively. The results showed that the addition of brown algae extract for feed at a dose of 20gr/kg had a more optimal effect than other treatments because of the bioactive compounds it contained. The dose had an effect on the growth of absolute length (1.6 cm), absolute weight (126.3 g), SGR (2.39%), FCR (2.28), EPP (44%) and water quality values during the maintenance period were still in the optimal range for god fish seeds.

Abstract

Aeromonas hydrophila is a facultative anaerobic bacteria, namely bacteria that can grow in conditions with or without oxygen. One of the diseases that fish farmers fear is red spot disease or Motile Aeromonas Septicemia (MAS) which is caused by A. hydrophila. Therefore, it is necessary to use alternative materials that can be used to eliminate A. hydrophila, one of which is by using herbal medicines. A natural ingredient that can be used to treat fish attacked by bacteria is noni leaves (Morinda citrifolia). The aim of this research was to determine the active compound content in noni leaf extract (M. citrifolia) and the use of noni leaf extract (M. citrifolia) on the hematology of gouramy fish. The results of the Column Chromatography (KK) test showed that the crude extract of noni leaves was positive for alkaloids, saponins, triterpemoids and flavonoids. And in the GC-MS test, it was discovered that the most dominant phenolic compounds contained in noni leaf extract. The results of hemotological data analysis based on the ANOVA test showed that administration of noni leaf extract (M. citrifolia) had a significant effect (p<0.05) on hematocrit, erythrocytes, leukocytes and hemoglobin. Based on the results of observations of the parameters seen, treatment of gouramy fish (Osphronemus gouramy) infected with A. hydrophila bacteria at an optimal dose of 360 ppm.

Abstract

According to BKIPM-KKP data, throughout 2022 - 2023 there were a total of 29 cases or 0.028% of the total 102,570. The cause was the finding of heavy metal content such as mercury that exceeded the threshold, namely 2 cases in Germany and 2 cases in France. In addition, 1 rejection case in Spain related to the lack of temperature control, and 1 case in Russia related to the finding of E. coli bacteria. One of the considerations for consumers in choosing products to be consumed is to ensure that the food produced is safe for health with guaranteed hygiene. The implementation of good production methods and sanitation procedures is based on a standard guideline, namely Good Manufacturing Practices (GMP) and Standard Sanitation Operating Procedure (SSOP). This study aims to determine the GMP and SSOP of frozen red snapper fillets. The methods used were observation, interview, and active participation. The results of the cold chain implementation are in accordance with the standard, the results of the yield calculation are in accordance with the company standard of 43-44%, the results of GMP and SSOP analysis have met the standards of PERMEN KP Number 17 of 2019.

Abstract

The Pedada fruit (Sonneratia caseolaris) is highly nutritious, containing vitamins A, B, B2, and C and phytochemicals such as flavonoids, steroids, and alkaloids. This study aims to develop Pedada fruit slice jam to enhance the practicality of conventional jam. However, the final product's unattractive color necessitates using natural colorants and bioactive compounds to enhance antioxidant activity. Roselle flower extract (Hibiscus sabdariffa L.), rich in anthocyanins with antioxidant properties, was used as a natural colorant. This research examines the effect of roselle extract on the antioxidant activity and acceptability of Pedada fruit sheet jam using a Completely Randomized Design (CRD) with four treatments: control (without roselle extract), and additions of 30% (P1), 40% (P2), and 50% (P3) roselle extract, each with five replications. Antioxidant activity, hedonic testing, and proximate analysis (carbohydrates, fats, moisture, ash, and protein) were measured. Data analysis was performed using SPSS with one-way ANOVA and Duncan's Multiple Range Test (DMRT) at a 95% significance level. The results show that adding roselle extract significantly enhances antioxidant activity, with the highest IC50 value observed at the 50% treatment (P3) at 25.380 ppm, compared to the control (P0) at 55.429 ppm. Furthermore, the addition of roselle extract improves product acceptability.

Abstract

Transportation is a follow-up activity in cultivation that is useful for moving fish to new habitats. The transportation system used is a closed system that relies on oxygen in it. This system has disadvantages, such as fish being easily exposed to stress due to decreased water quality in the media and disruption of fish metabolism. Therefore, an alternative strategy is needed by anesthetizing the fish to reduce movement and metabolism during transportation. The anesthetic used is sweet potato leaves which contain saponins (21,50%), flavonoids (1,30%), and polyphenols (4,0947 mg/g). This research aims to apply the use of Ipomoea batatas sweet potato leaf extract mixed into water media in the transportation process of prospective black tilapia broodstock Oreochromis niloticus. The research used a completely randomized design (CRD) method consisting of three replications and four treatments, namely treatment K (control), P2 (2 mg/L), P4 (4 mg/L), and P6 (6 mg/L). The results of the research can be concluded that the best treatment in this study was P6 which showed higher survival rates and lower blood glucose levels compared to other treatments (P<0.05), while the water quality parameters between treatments did not significant different.
