Abstract

Ciparagejaya Village is one of the villages in Karawang Regency that is directly adjacent to the Java Sea waters and is dominated by fisheries activities such as capture fisheries, sea product auctions, and processing of fish caught in the sea. The existence of weather factors and moon phases can affect fishing catches which have an impact on fishermen's income, purchasing power of fishermen's households, and the level of welfare of fishermen's households. The purpose of this study is to analyze the amount of fishermen's household income from the fisheries sector which includes capture fisheries and non-fisheries and analyze the expenditure of fishermen's households which includes food and non-food expenditures, and analyze the level of welfare of fishermen's households based on the Exchange Rate of fishermen (NTN) in May 2024 in Ciparagejaya Village, Tempuran District, Karawang Regency. The method used in this research is the survey method and this research was conducted with a quantitative descriptive approach. Sampling was done purposively by involving 96 boat-owning fishermen residing in Ciparagejaya Village, Tempuran Subdistrict, Karawang Regency. This study used primary data and secondary data. Primary data was obtained through interviews using a questionnaire and secondary data was obtained through relevant agencies. The results showed that the average income from capture fisheries and non-fisheries in May 2024 amounted to Rp 2,832,158 and Rp 1,620,000. The average food and non-food expenditure of fisher households in May 2024 amounted to Rp 973,281 and Rp 713,135. The average welfare level based on the Fisherman Exchange Rate (NTN) indicator in May 2024 was 1.89. This shows that fisher households can fulfill their primary and non-primary needs.

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

Tilapia as a food ingredient has a high nutritional content, one of which is protein content. Tilapia meat can be processed into flour, which can then be used as an ingredient to increase the nutritional content of dried sus. This study aims to determine the amount of tilapia meat flour added to produce dried sus that is most favored by panelists. The method used was an experimental method with 0%, 10%, 15%, and 20% tilapia meat meal addition. The parameters observed were the hedonic test and the proximate test. The results showed that the addition of tilapia meat flour to the most preferred dry sus was the 15% treatment with an average value of appearance of 8.0; aroma of 7.7; texture of 8.4; taste of 7.9; criterion weight of 0.57 and alternative value of 8.8. The resulting proximate test is water content of 4.86; ash content of 2.91%; protein content of 12.35%; fat content of 31.95%; and carbohydrate content of 45.52%.

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.
