Abstract

The fermentation process has been known for a long time, this process basically occurs in a food. At the beginning of its appearance, the fermentation process is used by many western countries to create a food that has many flavors. In tilapia, there are carbohydrates, protein, fat, as well as a number of vitamins B3, B12, potassium, phosphorus, and selenium. For many people, besides being high in nutrition, and having a savory and sweet taste, fish sauce is also very easy to make and the cost to make it is quite cheap and doesn't take a long time. The aim of this study was to determine the effect of traditional salt concentration and the effect of fermentation time on the quality of fish sauce. The research method used was an experiment with Completely Randomized Design (CRD) as the experimental design. The treatments used were the addition of saline solution concentration and fermentation duration, each treatment was repeated 3 times. The independent variables in this study were the concentration of traditional salt used and the time of fermentation. The controlled variables in this study were Streptococcus lactis bacteria, pineapple fruit, temperature, pH and tilapia. The dependent variable measured was the quality of tilapia fish sauce using proximate analysis and NaCl test in percent (%). In this investigation, the optimal treatment was a 7-day fermentation with a 5% saline solution concentration (W3K1), with a protein content of 17.38%, water content of 68.66%, ash content of 8.12%, fat content of 10.85%, and 0% carbohydrate content

Abstract

The longtail tuna (Thunnus tonggol) is one of the highest-producing fishery commodities in the waters of West Sumatra. Its abundance is influenced by oceanographic conditions, particularly indicated by chlorophyll-a concentration as a marker of water productivity. This study aims to examine the distribution of chlorophyll-a in relation to the catch of longtail tuna (Thunnus tonggol) using Aqua MODIS imagery in the waters of West Sumatra. The method used in this research is observational, involving data collection on chlorophyll-a distribution and logbook records. Chlorophyll-a data was obtained from the Ocean Color website, and logbook data for 2018–2022 was sourced from the Bungus Oceanic Fisheries Port (PPS). The results show that chlorophyll-a distribution in the waters of West Sumatra fluctuated between 2018 and 2022, with an average range of 0.15 mg/m³ to 0.33 mg/m³. A simple linear regression analysis showed a significant F-value of 0.0045, which is smaller than α (0.05), indicating that the regression equation is valid. This suggests that the distribution of chlorophyll-a has a significant effect on the longtail tuna catch in the waters of West Sumatra. The average annual CPUE (Catch Per Unit Effort) of longtail tuna was 0.44 tons/trip, with an average catch over the 2018–2022 period of 18.38 tons and an average of 41 trips per year.

Abstract

Indonesia is the world’s largest producer of seaweed, contributing 16.2% to the global market, yet most of its seaweed is still exported in raw form. This limits added value creation and hinders the growth of micro, small, and medium enterprises (MSMEs). NORIbet, a seaweed-processed MSME based in Bandung, West Java, aims to address this gap by developing value-added seaweed products. However, the business still faces challenges in cost management, marketing, and technology access. This research was conducted from June to October 2024 to analyze NORIbet's business profile using the Business Model Canvas (BMC) and evaluate its financial feasibility. A descriptive case study approach combining qualitative and quantitative methods was used, with data collected through observations and interviews involving two business owners and two production staff, selected using purposive sampling. Financial feasibility was analyzed through indicators such as profit, revenue cost ratio (R/C), break even point (BEP), payback periods (PP), and sensitivity analysis. Findings indicate that NORIbet successfully implements the 9 BMC elements in a well-structured manner. The business earned an annual profit of IDR 766,334,100 with a profitability rate of 56.1% and an R/C ratio of 2.28. Payback period is estimated at 4.6 months, and each product packaging type has its own BEP unit. Sensitivity analysis showed that a 10% increase in cost reduced profitability to 51.7%, while a 10% cost reduction increased it to 60%, indicating strong cost efficiency and operational resilience. These results confirm that NORIbet is highly feasible and has strong development potential.

Abstract

This study aims to analyze the influence of environment, experience, education, temperature, work hour, age, fishermen group, access internet, and government aid on post-harvest fish losses. The sample of this study was taken from Banyuwangi district consisting of Muncar and Blimbingsari sub-districts, and Lamongan district consisting of Paciran and Lamongan sub-districts. This study uses a quantitative approach and regression estimation using Ordinary Least Square (OLS), to see the influence between the independent variables on the dependent variables in the study. The results of this study show that the variables of environment, education, experience, and fishermen group have a significant influence on post-harvest fish loss. In addition, the highest post-harvest fish loss (PHFL) was found in Blimbingsari sub-district, Banyuwangi district. Another location with a high PHFL value was Muncar sub-district. In contrast, Paciran and Brondong sub-districts in Lamongan district had lower PHFL values. The findings have managerial and academic implications. For policy makers and fisheries organizations, the results of this study highlight the need to increase access to efficient storage technologies and provide training to improve fishers' skills in post-harvest handling. Academically, this study contributes to the fisheries economics literature by offering empirical evidence on the key factors affecting PHFL in small-scale fisheries. There are still gaps in integrated empirical studies and in policies that address human resources and institutional support. Therefore, this study provides important insights for designing more holistic and targeted strategies to reduce PHFL in East Java.

Abstract

Milkfish production can be increased in aquaculture if feeding and the use of artificial high protein feed can be optimized. Optimal feeding can be done by adding probiotics to the feed, one of which is by using EM4. This study aims to compare the concentration of the addition of probiotic EM4 in commercial feed so that optimal growth of juvenile milkfish (Chanos chanos) is obtained. This research was conducted in the community ponds of Toiba Village, Bualemo District, Banggai Regency from May to July 2022. This research uses an experimental method which is carried out in one pond plot. There were nine fixed cages with a width of 30 cm and a height of 30 cm used for maintenance. The experimental design used in this study was a completely randomized design (CRD) with 3 treatments and 3 replications. Parameters observed in this study were Specific Growth Rate (SGR), Feed Conversion Ratio (FCR), Survival (SR) and water quality. The results of the research showed that treatment B provided the best Specific Growth Rate and Feed Conversion Ratio for juvenile milkfish because the difference in the number of bacteria contained in EM4 probiotics can affect the absorption of fish nutrients because the more bacterial population in the digestive tract will increase the availability of nutrients that are ready to be absorbed in the digestive tract. This increase in digestibility is the same as the higher nutrients available to be absorbed by the body which will affect growth and Feed Conversion Ratio.

Abstract

Tourism is a strategic sector that plays a significant role in driving economic growth and improving community welfare. Banyuwangi Regency possesses substantial coastal tourism potential, one of which is Cacalan Beach. Despite offering appealing natural attractions, good accessibility, and active digital promotion through electronic word of mouth (e-WOM), the abundance of similar beach destinations presents a challenge for Cacalan Beach in maintaining its competitiveness as a top choice for tourists. This study aims to analyze the influence of tourist attraction, accessibility, and e-WOM on tourists' visit decisions, with visiting interest as a mediating variable. The research employed a quantitative descriptive approach, involving 140 respondents who met the criteria, using a questionnaire as the data collection tool. Data were analyzed using Structural Equation Modeling Partial Least Squares (SEM-PLS) with WarpPLS version 8.0. The results indicate that tourist attraction has a direct influence on visit decisions, while accessibility and e-WOM do not show a direct effect. However, all three variables significantly enhance visiting interest, which in turn contributes to an increase in actual visits to Cacalan Beach. These findings highlight that visiting interest plays a crucial role in encouraging tourists' decisions to visit.

Abstract

Whiteleg shrimp (Litopenaeus vannamei) cultivation is one of the rapidly growing aquaculture sectors in Indonesia, especially in West Sumatra Province. However, the success of this cultivation is greatly influenced by feed efficiency, water quality, and shrimp health. The use of probiotics is one of the strategies that are widely developed to improve cultivation performance in a sustainable and environmentally friendly manner. This study aims to compare the effectiveness of two types of probiotics, namely Bacillus spp. and Lactobacillus spp., on the growth and survival of whiteleg shrimp in a semi-intensive pond system. The study was conducted experimentally in Padang Pariaman Regency using a Completely Randomized Design (CRD) consisting of three treatments and three replications: P1 (control without probiotics), P2 (Bacillus spp. probiotics), and P3 (Lactobacillus spp. probiotics). The parameters observed included daily growth rate, survival rate, feed conversion efficiency (FCR), and water quality (pH, DO, NH₃, and salinity). Data were analyzed using ANOVA test and continued with DMRT test at a significance level of 5%. The results showed that the P2 treatment gave the best results significantly on all main parameters. Bacillus spp. has been shown to increase growth rate, survival rate, feed efficiency, and stabilize pond water quality. The P3 treatment showed intermediate results, while P1 showed the lowest performance. Thus, Bacillus spp. is the most effective probiotic to support vaname shrimp cultivation in a semi-intensive system.
