Abstract

Fishing activities using sondong fishing gear are classified as small-scale, with the main catch being shrimp. Shrimp is a fishery commodity that has high economic value, so fishing activities using this fishing gear should provide profits. However, it is currently unknown whether this fishing activity benefits fishermen. The research aims to assess the feasibility of using sodong fishing gear in Babalan Village, Demak, Central Java. The method used is a survey with direct interview techniques to fishermen using a questionnaire. The research sample used was 30 fishermen who were chosen randomly. Data analysis uses cost, income, profit, Revenue Cost Ratio, Benefit Cost Ratio, Payback Period, Net Present Value, and Internal Rate of Return analysis. The research results show that the average investment cost incurred by fishermen is IDR. 17,000,000. The total costs incurred in 1 year average Rp. 105,244,000. The income and profits earned differ in each season. The R/C value for each season from this fishing effort is >1, meaning this business is feasible and provides profits. The Net B/C value of this business is 5.9, meaning this business is feasible. Payback period analysis shows a return on capital of 9 months. The NPV value in this fishing effort is positive. The IRR value is 8.15% > 7% interest rate.

Abstract

This study aims to analyze the addition of EM-4 probiotics with different concentrations to the cultivation media on the growth and survival of freshwater pomfret fish (C. macropomum). This research was carried out for 50 days at the Fish Production and Reproduction Laboratory, Aquaculture Study Program, Faculty of Agriculture, Mataram University. The method used was an experiment using a Completely Randomized Design (CRD) consisting of 4 treatments and three replications, namely without the addition of probiotics or control (P1); probiotic EM-4 0.5 ml/L (P2); probiotic EM-4 1.5 ml/L (P3); and probiotic EM-4 2.5 ml/L (P4). Test parameters include absolute weight, absolute length, specific growth rate, survival rate, feed conversion ratio, feed utilization efficiency, air quality, and bacterial density. Data analysis used analysis of variance (ANOVA) at a confidence level of 95%. If the research results show significant differences, further tests use the Duncan Multiple Range Test (DMRT). The research showed that adding EM-4 probiotics to the rearing media at different concentrations could significantly affect (p<0.05) fish survival rate, absolute weight, specific growth rate, feed conversion value, and feed utilization efficiency. The treatment of adding EM-4 probiotics to the maintenance media with a concentration of 1.5 ml/L of air provides the best value for survival rates, growth, FCR, and EPP. It can maintain the quality of the cultivation media in good condition for the growth of freshwater pomfret (C. macropomum).

Abstract

White vanamae shrimp is one of the superior commodities in aquaculture. Currently, the productivity of white vanamae shrimp has not yet reached its production target. So, it is necessary to increase the amount of production on a gradual scale carried out by the community. In shrimp farming activities, disease problems are often encountered. Namely is a white stool, white feces, or White Feces Disease (WFD). The clinical symptoms that arise when shrimp are attacked by White Feces Disease (WFD) are that the shrimp's appetite decreases, the shrimp's intestines change color to white and even look empty due to lack of food intake, white feces floating on the surface of the water, and the shrimp's growth becomes abnormal. This WFD disease can be caused by poor cultivation practices, unhealthy seeds, and poor water quality, causing the emergence of disease microorganisms such as Vibrio sp bacteria. One way to treat this disease is to provide alternative medicine, noni fruit extract. This research consisted of 3 noni extract treatments and consisted of 3 replications, namely Treatment A: 10 mL/L; Treatment B: 15 mL/L; Treatment C: 20 mL/L. The noni dose is given at the specified dose once daily for one month. The survival rate of shrimp increased to 86.7%.

Abstract

Coastal and marine areas hold great wealth for the welfare of coastal and small island communities with dynamic magnitudes. Panggang Island and Semak Daun Island have the potential for promising coastal and marine resource assets and provide benefits for community welfare. The research aims to compile a balance sheet of coastal and marine resource assets for Panggang Island and Semak Daun Island. The research was conducted in the Seribu Islands Administrative District, DKI Jakarta Province, in August-September 2023. It included various information data to map the value of ecosystem services and asset balances. The economic valuation method using the benefits transfer technique is used as input for the value of natural resource assets and the coastal and marine environment. The research results show that the value of coastal and marine resource assets of Panggang Island and Semak Daun Island have quite significant dynamics. In 2014-2019, the coastal and marine resource assets of Panggang Island and Semak Daun Island experienced a considerable decline, namely 1,001.92 billion ( Panggang Island ) and 59.97 billion ( Semak Daun Island ). They decreased respectively by 200.38 billion per year (12.34%) and decreased by 11.99 billion/year (9.29%). The estimation results show that there will be an improvement in asset value in 2022 for Panggang Island to 687.73 billion and for Semak Daun Island to 82.32 billion. The estimation results show that there has been an improvement in the ecosystem during the 2020-2022 period. This increase is due to reduced pressure on coastal and marine ecosystems on the two islands. Ecosystem-based integrated management needs to be carried out so that the sustainability and value of resource assets can benefit the welfare of coastal and small island communities.

Abstract

This research was conducted in Kiluan Village, Kelumbayan District, Tanggamus Regency. This study examines the essence of managing marine park tourism by focusing on the surrounding environment (Community-based Management) in Kiluan Negeri, Tanggamus Regency. The research was conducted by descriptive analysis of qualitative approaches through direct studies (primary data) and existing data (secondary data). Kilian Negeri has beautiful and unique marine resources. Problems in Kiluan Bay are related to economic inequality, limited resources, environmental damage due to garbage, and the threat of natural disasters. The general public still needs to learn how involved they are in managing marine park tourism appropriately and sustainably. The active participation of NGOs, namely the NGO Cikal, plays an important role in managing the Kiluan Bay conservation area. Some Community-Based Management (CBM) strategies that can be done are preparing tourism development plans, developing infrastructure, managing tourist destinations, holding promotions and marketing, developing tourism products, conducting HR training, collaborating with the private sector, and developing integrated tourist areas. Community-based management (CBM) of marine park tourism is based on recognizing the importance of local communities in maintaining the sustainability of the marine environment and obtaining economic and social benefits from the tourism sector.

Abstract

Gonad maturity in fish is essential in fish farming because it is related to seed production. Sesame oil is one of the ingredients as a feed supplement to stimulate fish gonad maturation. The research aimed to obtain the best dose of sesame seed extract (Sesamum indicum L.) in feed to increase the gonad maturity of comet fish (Carassius auratus). This research had four treatment levels and three repetitions. The treatment levels in this study were: P0 Without giving sesame seed extract (Control), P1 Giving sesame seed extract 5 mL/kg feed, P2 giving sesame seed extract 10 mL/kg feed, P3 Giving sesame seed extract 15 mL/kg. The results of the six-week study showed that at the beginning of maintenance, they were in TKG I, in the 3rd week, they entered TKG III, and in the 6th week, P1, P2, and P3 entered TKG IV while P0 were still in TKG III. The highest gonad maturity index at each observation time occurred in treatment P2 with feed containing 10 mL/kg of sesame seed extract. In the 1st week, the highest gonad maturity index occurred at P2 at 7.80. In the 3rd week, the highest gonad maturity index occurred in P2 at 9.26%. In the 6th week, the highest gonad maturity index occurred in P2 at 11.17%. Fecundity at week 6 showed the highest result of P2 4,290. The level of gonad maturity with treatment given sesame extract was faster, with a maintenance time of 6 weeks. The results of this study illustrate that sesame extract can be used as a supplement to increase comet fish gonad maturity.

Abstract

Abstract This research aims to observe the distribution and changes in the area of mangrove vegetation in Jawai District, Sambas Regency, West Kalimantan Province. This sub-district is part of the administrative area of Sambas Regency and is one of 6 sub-districts that have coastal regions. The data used in this research is Landsat 8 satellite imagery, recording data from 2016 and 2022. The results of the data analysis show that of the total of 13 villages, only one village did not find mangrove vegetation in its area, namely Dungun Laut Village. Based on the analysis of the distribution of mangrove vegetation in 12 villages, there are two villages, namely Mutus Darussalam and Sarang Burung Danau, which show a decrease in the area of mangrove vegetation cover. Both experienced a reduction in the area of 0.184 ha and 42,081 ha, respectively. During 2016 and 2022, the lowest mangrove vegetation area was in Sentebang Village, 2,768 ha and 19,112 ha. The highest area of mangrove vegetation is increasing in Sarang Burung Kolam Village, with an area of 188,889 ha (2016) and 212,335 ha (2022). These findings show the importance of conservation in protecting the mangrove ecosystem in this area.

Abstract

Freshwater lobsters are one of the crustacean commodities that have started to be developed through cultivation. Besides having high nutritional value, freshwater lobsters have a stable sales value or price throughout the year. Freshwater lobster is a crustacean commodity that is not easily stressed or easily attacked by disease. The availability of calcium is essential for lobster growth, especially the formation of its shell. This research aims to determine the effectiveness of adding calcium carbonate at different time intervals by adding 150 mg/L CaCO3 lime. The study was conducted from June to July 2020 at the Aquaculture Environmental Laboratory, Bogor Agricultural Institute. The research used a Completely Randomized Design (CRD) with five treatments and three replications. The treatment used was K+ and K-, and the time interval for adding CaCO3 was once every five days, once every ten days, and once every 15 days. The aquarium measures 100 x 50 x 51 cm with a water height of 21 cm. The lobster used measures 1.5 cm. The research results after statistical testing showed that aquarium A1 (addition of CaCO3 every five days) experienced an increase in length of 0.67 cm. Weight of 0.67 g, B1 (addition of CaCO3 every ten days) experienced an increase in length of 0.87 cm and weight of 0.78 g, C1 (addition of CaCO3 every 15 days) experienced an increase in length of 0.97 cm and weight of 0.98 g, K+1 experienced an increase in length of 1.05 cm and weight of 1.06 gr, K-1 experienced an increase in length of 0.46 cm and weight of 0.45 g.

Abstract

Seaweed is the primary source of carrageenan, but it also contains iodine, which can inhibit bacterial activity and growth. The iodine contained in seaweed results from interaction with the marine environment rich in iodine. The research was conducted from June to November 2022 and used iodine from seaweed extraction to test antibacterial activity (Staphylococcus aureus and Salmonella sp). The antibacterial activity test was carried out for 48 hours. The iodine concentration was determined using titration, while the antibacterial activity test used the Disc Diffusion Test. The research showed that Eucheuma spinosum extract contained iodine, 0.38% - 1.22%. The antibacterial activity of seaweed iodine test results revealed an average inhibition zone diameter of 11.5 mm for Staphylococcus aureus and 12 mm for Salmonella sp. This research shows that the iodine in Eucheuma spinosum extract has an inhibitory solid impact on the activity and growth of Staphylococcus aureus and Salmonella sp.
