The research design used was a completely randomized design with 4 treatments, each with 3 replications. The treatment in this study was based on the concentration of broccoli added, namely B0 (0%), B1 (25%), B2 (50%) and B3 (75%). Parameters observed were crude fiber, potassium, and organoleptic value of catfish nuggets. The results showed that the addition of broccoli at various concentrations had a significant effect (P<0.05) on crude fiber, and potassium value but had no significant effect on organoleptic values. The most preferred nuggets with the addition of broccoli was treatment B1 (25%). The addition of broccoli in the processing of catfish nuggets can increase crude fiber and potassium.

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

Based on data from FAO (Food and Agriculture Organization of The United Nations), it has been predicted that the aquaculture subsector will become one of the most relied-upon resources in the future, especially in meeting food needs, fish-based nutritional needs, and empowering the global community's economy (FAO, 2016). Catfish is a type of freshwater fish that can grow and develop well because it can be cultivated in limited land areas (Marsela, 2018). The frequency of feeding is one of the important factors that need to be considered in catfish farming. To determine the effect of different feeding frequencies on the absolute weight of dumbo catfish, a study was conducted using an experimental design called the Completely Randomized Design (CRD), with 3 treatments and a total of 8 replications. The test treatments were as follows: Treatment 1 (feeding twice a day), Treatment 2 (feeding three times a day), and Treatment 3 (feeding four times a day). The results of the ANOVA test showed a significant value of 0.000 (P < 0.05), indicating a significant difference in each of the different feeding frequencies. The analysis of the Least Significant Difference (LSD) test at a 5% significance level also showed that the relationship between each treatment had a significant value of 0.000 (P < 0.05). The average absolute weight of the fish for Treatment 1 was 12.99 grams, for Treatment 2 was 15.03 grams, and for Treatment 3 was 17.03 grams. The highest growth in the absolute weight of dumbo catfish fry occurred in Treatment 3 (feeding four times a day).

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.

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?"
