This study aims to analyze in depth the structure of production cost components and determine a reasonable and competitive selling price for shrimp farming in the Venambak Shrimp Farm. The background of this study is the need to determine the cost efficiency and profit potential of shrimp farming activities, so that business actors can make the right decisions and be oriented towards sustainability. The study uses a quantitative descriptive approach with the full costing method to calculate the total production costs, and the cost plus pricing method to determine the selling price. The data used consists of primary data, such as details of operational expenses during one cultivation cycle (six months), as well as secondary data obtained from internal company reports and records. The results of the analysis show that the total production costs incurred in one shrimp cultivation cycle reached Rp16,085,208,000, with a total harvest of 1,000,000 kg. Based on these figures, the cost of goods manufactured (COGS) was obtained at Rp16,085 per kg. In determining the selling price, the company used the cost plus pricing method and set the selling price at Rp80,000 per kg. Thus, the profit margin obtained by the company reached Rp63,915 per kg. Gross profit generated during one cultivation cycle reached Rp63,915,000,000. If cultivation were conducted in two cycles per year, the annual gross profit could potentially increase to Rp127,830,000,000. These findings indicate that with efficient cost management and the right pricing strategy, shrimp farming has significant profit potential. Therefore, intensive and sustainable shrimp farming development at the Venambak Shrimp Farm is highly feasible to improve the competitiveness and welfare of fisheries business actors.

This study aims to analyze the influence of Product Quality, Price, Sales Promotion, and Advertising on consumer purchasing decisions on the Bukalapak online store platform. This study used a quantitative approach with descriptive methods, aiming to illustrate the relationships between variables based on empirical data. Primary data were obtained by distributing questionnaires to 120 respondents who were active Bukalapak users in the West Medan District. The data analysis technique used was multiple linear regression with the aid of SPSS software to determine the effect of each independent variable on the dependent variable. The analysis results indicate that, partially, the variables Product Quality, Sales Promotion, and Advertising have a positive and significant influence on purchasing decisions. This means that the higher the product quality, the more effective the promotion, and the more attractive the advertisement, the greater the likelihood of consumers making a purchase. Conversely, the variable Price showed a negative and significant influence, indicating that inappropriate pricing can reduce purchase intention. Simultaneously, all four variables have a significant influence on purchasing decisions. The Adjusted R Square value of 70.4% indicates that this research model is able to explain 70.4% of the variation in purchasing decisions, while the dependent variable is influenced by factors outside the model. This study recommends that Bukalapak continue to improve product quality, develop competitive pricing strategies, strengthen promotions, and create creative advertising. Further research is recommended to consider additional variables such as product reviews, brand image, and service quality to enrich the analysis.
