This study aims to analyze the environmental impact of waste generated by the gecko processing home industry based on environmental law regulations in Indonesia. In its processing activities such as lizards and snakes. These activities produce organic waste in the form of animal organs, blood, body fluids, and other waste in the materials that are later utilized as catfish feed. The research method used is qualitative with a normative juridical approach, statutory approach, and literature study. Data were obtained from laws and regulations , scientific journal, and environmental law literature. The results of the study indicate that the disposal of waste into rivers can increase Biological Oxyen Demand and Chemical Oxygen Demand (COD) levels, cause unpleassant odors, and reduce water quality and public health. The utilization of waste as catfish feed can reduce the amount of waste disposed of, however, it still requires hygienic processing to prevent biological risks. From the perspective of environmental law, the direc disposal of the waste into rivers is not in accordance with Law No. 32 of 2009 concerning Environmental Protection and Management and Government Regulation No. 22 of 2021 concerning the Implementation of Environmental Protection and Management. Therefore, better waste management is needed through proper waste treatment, increased awareness among business actors, and goverment supervision so that home industries can operate sustainably and in an environmentally friendly manner

This study aims to determine the ideal stocking density of catfish using the triple integral method. This mathematical method is applied to accurately calculate the volume of the cultivation pond and analyze the stocking amount and biomass projection at three different density levels, namely 50, 75, and 100 fish/m³. The calculation of the volume of the pond measuring 27 m x 11 m x 1.5 m produces a value of 445.5 m³. Based on the integral calculation, the optimal stocking amount is 22,275 fish, 33,413 fish, and 44,550 fish for each density, with the final biomass projection reaching 300.7 kg, 451.1 kg, and 600.4 kg, respectively. The analysis shows that the density of 100 fish/m³ produces the highest biomass, but its application must consider technical factors such as water quality, oxygen availability, and food competition. This method provides a solid and practical mathematical foundation for more efficient, scalable, and sustainable aquaculture planning.

This study aims to analyze inventory control of catfish seeds at ABC Company by comparing the conventional inventory method represented by the Economic Order Quantity (EOQ) approach and the Just In Time (JIT) system in order to improve cost efficiency. This research employed a descriptive quantitative approach using a case study design. Data were collected through direct observation, semi-structured interviews with company management, and documentation of inventory and cost records for the 2024 operational period. The analysis method involved calculating optimal order quantities, ordering frequency, delivery frequency, and total inventory costs using EOQ and JIT formulas, followed by a comparative cost efficiency analysis. The results show that the conventional method resulted in a total inventory cost of Rp 75,050,000 per year with high ordering frequency. In contrast, the implementation of the JIT system reduced inventory costs to Rp 18,762,500 per year, achieving a cost efficiency of 72%. These findings indicate that the JIT system is more cost-efficient than the conventional method; however, its implementation requires careful consideration of supplier capacity, logistics readiness, and biological risks associated with live inventory. This study contributes empirical evidence on the applicability of JIT in the aquaculture sector, which has different characteristics from manufacturing industries.

This study aims to evaluate the effectiveness of the implementation of the public sector accounting cycle in the planning, implementation, administration, and evaluation of catfish cultivation programs run by BUMDes Ajoeng Jaya as part of the village food security program. The focus of the research departs from the need to ensure that each stage of the management of the BUMDes program runs according to the principles of public accountability, considering that BUMDes is a strategic entity in the management of village resources to improve the welfare of the community. This study uses a qualitative descriptive approach through field observation, in-depth interviews with the management of BUMDes Ajoeng Jaya, and a review of documentation related to catfish farming program activities and financial records. This approach allows researchers to gain a comprehensive understanding of the accounting practices applied as well as the various obstacles that arise during the implementation of food security programs. The results of the study show that the catfish cultivation program has failed due to weak internal supervision, the absence of SOPs, lack of financial recording and reporting, and lack of technical competence of managers. The implementation of the public sector accounting cycle has not been running optimally so that it is not able to support effective control and evaluation of programs. In addition, crop failures are exacerbated by theft by internal parties and the absence of a structured monitoring system throughout the program, which indicates weak governance and internal control. This study has limitations in the form of a small number of informants and a lack of formal documents, so the analysis—especially the financial aspect—cannot be generalized widely. Nevertheless, this study contributes by integrating the evaluation of food security programs through the implementation of the public sector accounting cycle and offering recommendations to improve the accountability, transparency, and sustainability of BUMDes programs.

Feed is a key component in catfish (Pangasius hypophthalmus) cultivation because it directly affects the growth rate, health, and productivity of the fish. Among the various nutrients contained in feed, protein plays a crucial role, particularly in the formation and repair of fish body tissues. Adequate protein content supports optimal growth, while protein deficiency can reduce productivity. Therefore, analyzing protein levels in feed is essential to ensure its quality. This study aimed to analyze protein levels in catfish feed using the Kjeldahl method. The analysis was conducted at the Pekanbaru Center for Standardization and Industrial Services (BSPJI). The Kjeldahl method was chosen because it is known to have a high level of accuracy and reliability. The procedure involves three main stages: destruction, distillation, and titration. The working principle of this method is to convert organic nitrogen in the sample into ammonia, which is then captured and measured to determine nitrogen levels, which are then converted to protein levels. In this study, five feed samples with codes U-139 to U-142 were used. The test results showed that the protein content of the samples ranged from 20.44% to 23.09%. Furthermore, a Relative Percent Difference (RPD) value of 0.0013% was obtained, indicating a very high level of measurement precision. The analysis results were then compared with the fish feed quality standards based on SNI 2534:2006, and it was found that all samples met the minimum protein content requirements. Thus, this study confirms the effective and accurate use of the Kjeldahl method in analyzing protein content in catfish feed. These results also provide important information for farmers and feed producers in ensuring the quality of feed used to support catfish farming productivity.

This study offers a significant contribution as a foundation for formulating empowerment strategies for environmentally and socially-based small-scale aquaculture enterprises at the village level.

Many fishery products come from fishing and cultivation, saltwater and freshwater fisheries, so a preservation process is needed to maintain the condition of the fish so that it remains good when marketed. In addition, it can increase the economic value of fish. In the Indonesian fisheries industry, various types of preservation, including freeze drying, are drying processes using vacuum pressure and cold temperatures. The freeze-drying process utilizes the phased nature of water to convert solid (frozen) forms into water vapor (gas) at a certain pressure and temperature. The vacuum pressure used ranges from -60.3 cmHg to -71.6 cmHg, and the mass of the fish ranges from 94 grams to 136 grams. The type of research is quantitative and uses experimental methods. The result is in the form of a remaining moisture content percentage of 40% in dried fish according to SNI standard No. 827300:2023. The Respone Surface Methodology (RSM) was used to process the data in this study. From the study, the best value of vacuum pressure was -66 cmHg and mass 102.5417 with a final result of 40%.

A Caesarean section, or C-section, is a surgical procedure where a baby is delivered through an incision made in the mother’s abdomen and uterus. To aid the healing of post-Caesarean wounds, mothers need not only antibiotics but also a diet that provides high-quality nutrition and adequate calories. The research question being investigated is: "Do Age, Parity, Education, and Occupation Affect the Healing Process of Post-Caesarean Wound Stitches?" This study uses a quasi-experimental design with a Post-test Only Control Group Design. The study population includes mothers who had a C-section at Pemalang Hospital. Participants were divided into two groups: 49 received catfish extract tablets (the experimental group), and 49 received standard wound care (the control group). Sampling was conducted using purposive sampling techniques. Data were analyzed through both univariate and bivariate methods. The results showed a p value of 0.000 for the experimental group and 0.046 for the control group (both p values < 0.05), indicating that catfish extract tablets significantly influence the healing process of post-Caesarean wound stitches..

The development of technology in the field of fisheries is very rapid along with facilitating human work in the field. Human work can be done by tools such as feeding catfish in ponds automatically. This job is easy to do, but problems will arise when catfish are not fed at night or are fed too late, then the catfish will eat smaller catfish so that it can be detrimental to catfish farming owners. With this background, the author created a "Catfish Feeding Control System Based on the Internet of Things (IoT) Using the Fuzzy Sugeno Method". This testing and discussion was carried out by functionally testing each component, testing the program using simulation and testing it as a whole. The results of testing the tool and taking data are expected to obtain valid data and the tool works according to its function and purpose as expected. From the results of the analysis and discussion of the research entitled "Internet Of Things (IoT) Based Catfish Feeding Control System Using the Fuzzy Sugeno Method" it can be concluded as a process of automatic fish feeding using the RTC module as a reference for catfish time three times a day with good results and the process of calculating the amount of fish feed 3 to 8% with fish weight from LOW to HIGH using Fuzzy Sugeno has worked well compared to the results of the BLYNK application.

Micro, Small, and Medium Enterprises (MSMEs) play a crucial role in supporting the national economy, particularly in the fisheries sector. This study was conducted through a direct interview with a fish farming MSME, GG Sawah Farm, managed by Legiono. The purpose was to explore the dynamics of catfish and pangasius farming businesses, including business history, capital needs, marketing strategies, and the challenges faced. The findings reveal that despite its promising economic potential, the business encounters various obstacles such as feed costs, seed availability, and climate changes. However, through innovations such as the use of alternative feed, social media marketing, and product diversification into the frozen food sector, the enterprise has managed to survive and grow. This study recommends improving production efficiency, increasing financial support, and encouraging collaboration with stakeholders to enhance the sustainability and development of small-scale fish farming businesses in Indonesia.

One of the problems of catfish cultivation (Clarias gariepinus) that can hinder this cultivation business is the slow growth of fish weight. The purpose of this study is to determine the effect of different administration of Mina Pro probiotics on the absolute weight growth of pearl catfish seeds measuring 5-7 cm in the maintenance tub. The method used in this study is an experimental method. The design used in this study was a Complete Randomized Design (RAL) with four treatments and six replicates. The treatment given is: addition of probiotics mina pro at a dose of 2 ml/kg of feed, 4 ml/kg of feed, 6 ml/kg of feed and without the addition of probiotics to feed. Other parameters that were also studied included water quality including temperature, pH and DO.

Giving probiotics such as probiotic boster on feed greatly helps the growth of absolute weight in Catfish seeds because the good bacteria contained in these probiotics help facilitate catfish seeds in digesting the feed so as to increase the efficiency of the feed. This study aims to see how effective the probiotic administration is. The study was conducted in Kramas District, Gianyar regency, Bali Province for 30 days using experimental methods, using a complete randomized design with a total of 4 treatments and 6 repetitions. Treatment A is by giving 3 ml of probiotic boster every 1 kg of feed. Treatment B by giving 5 ml probiotic boster every 1 kg of feed. Treatment C by giving 7 ml probiotic boster every 1 kg of feed. Treatment D by giving 9 ml probiotic boster every 1 kg of feed. In this study showed significantly different results on the addition of probiotic boster with different doses on the growth of absolute weight of catfish fry aged 1 month-2 months. Treatment D gave the highest result with an absolute weight gain of 55.33 grams, and treatment a showed the lowest result with an absolute weight gain of 25.17 grams. Water quality Data during the study obtained water temperature ranges from 27-29 oC, acidity ranges from 7-8, and dissolved oxygen ranges from 3.34 to 4.26 ppm. The results of the analysis of variance (ANOVA) of the three parameters of water quality there is no difference between the treatment and the life range of catfish fry (Clarias sp.)

The objective of this study was to determine the effect of different percentages of natural feed (Tubifex sp.) and artificial feed on the absolute weight gain of striped catfish (Pangasius hypophthalmus) fry. The study was conducted at PBIAT Muntilan for 30 days using an experimental method. A Completely Randomized Design (CRD) was applied with five treatments and five replicates. The treatments were as follows: A (100% pellet), B (75% pellet + 25% Tubifex sp.), C (50% pellet + 50% Tubifex sp.), D (25% pellet + 75% Tubifex sp.), and E (100% Tubifex sp.). ANOVA analysis showed that different proportions of natural feed (Tubifex sp.) and artificial feed significantly affected absolute weight gain. The most optimal feeding ratio for enhancing the absolute weight gain of striped catfish fry was found in treatment E, where 100% Tubifex sp. was provided, resulting in the highest absolute weight gain of 4.876 grams. Water Quality Parameters: During the study, the recorded water temperature ranged from 25.1 to 25.4ºC, pH ranged from 6.7 to 6.8, and dissolved oxygen ranged from 6.6 to 6.7 ppm. ANOVA analysis of these three water quality parameters showed no significant differences among treatments. However, the temperature was below the optimal range for the growth of striped catfish (Pangasius hypophthalmus) fry.

Pearl catfish (Clarias gariepinus) has advantages when cultivated, namely fast growth, efficient feed, has a uniform size and is resistant to disease (Matasina and Sartika, 2020). The success of a fish farming business can be determined by its feeding management, because feed that is consumed effectively by fish can make fish experience good growth (Hanief, et.al, 2014).The purpose of this study was to determine the effect of natural feeding of Daphnia magna and silk worms on the absolute weight growth of pearl catfish (Clarias gariepinus) seeds aged 5 days. The method used is an experimental method that aims to determine the effect of feeding Daphnia sp and silk worms on the absolute weight growth of pearl catfish seeds (Clarias gariepinus) aged 5 days in a controlled environment. This study was arranged in a completely randomized design (CRD) with 3 (three) treatments and each consisting of 9 (nine) repetitions, thus there were 27 experimental units. Treatment A 100% silk worm (control), treatment B: 100% Daphnia sp and treatment C 50% Daphnia sp and 50% silk worm. The parameter observed was absolute weight growth. The results showed that the highest absolute weight growth was obtained from treatment A at 1.22 g, then treatment C at 0.76 g and the lowest was treatment B at 0.33 g. Based on the LSD further test, all feed treatments had significant differences on the absolute weight of fish fry. Based on the LSD further test as a whole shows that all feed treatments have significant differences on the absolute weight of fish seeds.

This study aims to analyze the growth performance of catfish (Pangasius sp.) cultivated in a tarpaulin pond system. Patin fish farming is one of the leading fisheries subsectors in Indonesia due to its high market demand and high nutritional content. The tarpaulin pond system was chosen because it offers efficiency in water quality management and disease risk reduction. This study was conducted in Gunungsitoli in December 2024, using an experimental method that included measuring fish length and weight during the rearing period. The results showed that water quality, including temperature (26-28°C), pH (6.5-7.5), and dissolved oxygen level (5 mg/L), played an important role in determining the fish survival rate, which reached 90%. Feeding strategies with a combination of artificial and natural feeds (silkworms, Artemia) have been shown to significantly improve fish growth. The main challenges in this aquaculture include water quality fluctuations, fry adaptation, and disease management, which can be overcome with aeration technology, probiotics, and natural immunostimulants. With the right innovations, the tarpaulin pond system proves to be an efficient and sustainable farming method in supporting catfish productivity.

The rapid development of information technology has significantly impacted the business world, including Micro, Small, and Medium Enterprises (MSMEs).
