Abstract

The purpose of this study is to analyze, partially and simultaneously, the influence of seasonal cycles and fish price fluctuations on the financial literacy of fishermen in Sifalaete Ulu Village. Partially, this study aims to determine the effect of seasonal cycles on fishermen's financial literacy, as well as the effect of fish price fluctuations on fishermen's financial literacy. Simultaneously, this study aims to determine the effect of both variables together on fishermen's financial literacy. This study used a quantitative approach with data collected through questionnaires from 57 active fishermen. Data were analyzed using multiple linear regression to test the partial and simultaneous effects. The results show that partially, seasonal cycles have a negative and significant effect on fishermen's financial literacy, while fish price fluctuations have a positive and significant effect on fishermen's financial literacy. Simultaneously, seasonal cycles and fish price fluctuations have a significant effect on fishermen's financial literacy. Income uncertainty due to these two factors causes fishermen to experience difficulties in financial planning, lack savings or emergency funds, and tend to rely on debt. In addition, low levels of education and minimal financial literacy training also hinder effective financial management

Abstract

Production optimization is a key to increasing efficiency and profitability, especially in businesses such as UD. Tahu Nias in Hiligodu Ombolata Village, Gunungsitoli City, which operates in the tofu production sector. This research is motivated by the production challenges faced by the company, such as limited equipment, late raw material supplies, and an unskilled workforce, which impact the inefficiency of the production process and decrease the level of profitability. The method used in this study is a qualitative descriptive approach with data collection techniques through interviews, observation, and documentation. Informants consisted of the owner, production employees, and other support staff. The results of the study indicate that the production process at UD. Tahu Nias still has manual stages with limited use of machines, especially only at the soybean milling stage. The main obstacles in optimizing production include late raw material supplies, the lack of technology and training for employees. However, the company has made several efforts such as strategic raw material management and efficient division of labor among employees. The conclusion of this study is that production optimization at UD. Nias tofu can be improved through the use of advanced equipment in more modern production facilities, employee skills development through training, and improved production and distribution planning. By implementing these strategies, the company has the potential to sustainably increase operational efficiency and profitability.

Abstract

The main objective of this study is to compare and analyze the effectiveness of the MRP (Material Requirement Planning) method in optimizing raw material inventory management in the Nias Tofu business. This study uses a mixed method. Primary data in this study were obtained directly from the Nias Tofu business through observations and interviews, while secondary data were obtained from the company in the form of production data from the Nias Tofu Product business in 2024. Data analysis was conducted using descriptive analysis techniques and the steps taken in the method analysis.MRP. According to the analysis results, the 2024 soybean raw material purchasing and demand data using the conventional method showed a shortage of raw materials of 14,200 kg with an order frequency of 14 times. Inventory management experienced inefficiencies, namely storage costs of IDR 1,600,000 and ordering costs of IDR 400,000, and raw material shortages still occurred, while the application of the MRP method resulted in order planning with an order frequency of 6 times, a fixed order quantity of 16,784 kg, and a much lower total inventory cost of IDR 335,160. The implementation of the MRP method has proven successful in eliminating raw material shortages and reducing operational costs so that the production process runs more smoothly and efficiently. This study proves that the application of MRP is effective in managing raw materials and optimizing production in the Nias Tofu business, making a significant contribution to smooth production and inventory cost efficiency.

Abstract

This research is motivated by the phenomenon of cafe business competition in Gunungsitoli City, which demands effective marketing strategies, particularly in the utilization of promotional mixes and business location selection. The purpose of the study is to analyze how promotional mixes and location aspects play a role in increasing sales at Murai Coffee Gunungsitoli. The research method used is a qualitative approach with data collection techniques through interviews, observation, and documentation. The research informants consisted of the owner, employees, and customers of Murai Coffee. Data were analyzed using the Miles and Huberman model, which includes data reduction, data presentation, and conclusion drawing. The results show that Murai Coffee has implemented promotional strategies such as simple advertising, sales promotions, personal selling, public relations, and direct marketing that gradually increase customer interest. Meanwhile, the location factor, although not located in the city center, still provides sales opportunities through a comfortable atmosphere and quality service. However, challenges are still found in the comfort aspect, such as noise from outside and hot room temperatures, so that improvements to supporting facilities are needed. This research is useful for Murai Coffee in designing more optimal promotional strategies and location arrangements, for Nias University as a contribution to the development of marketing science, and as a reference for future researchers who want to study marketing strategies in the culinary sector.

Abstract

This study analyzes the financial condition of the Osseda Faolala Perempuan Nias Consumer Cooperative during the period January 2021–December 2024, focusing on the management of current assets, short-term liabilities, and the repayment rate of member loans. Data were processed using descriptive statistics and simple linear regression to assess the cooperative's financial balance and factors influencing business growth. The classical assumption test showed that the regression model met the feasibility criteria, both in terms of normality and autocorrelation, thus the analysis results were reliable. The t-test results proved that working capital had a positive and significant effect on cooperative business growth with a significance value <0.05. The coefficient of determination (R² = 0.887) confirmed that 88.7% of the variation in business growth was explained by working capital management. This means that the more optimal the management of working capital—including current assets, short-term liabilities, and member loans—the higher the cooperative's chances of growth and development. In addition to strengthening the existing literature, this study is consistent with the findings of Winata et al. (2023) on manufacturing companies and Herawati (2023) on savings and loan cooperatives, both demonstrated the importance of working capital management to financial performance. However, these results differ from the research of Rezki Erdian et al. (2022) on the retail sector, which found that receivables had no significant effect on profitability. This difference indicates that the relevance of working capital is highly dependent on the institutional context. Overall, this study confirms that optimal working capital management is not merely an administrative issue, but a strategic factor determining cooperative business growth and improving welfare. member.

Abstract

This study investigates the role of acquisition premiums in mergers and acquisitions (M&A) and their impact on shareholder wealth, focusing on five major Indian deals in pharmaceuticals, retail, banking, steel, and renewable energy sectors. Potential synergies often justify acquisition premiums ranging from approximately 15% to 40% above target companies’ market values. However, market responses suggest that such premiums may not consistently result in value creation for acquiring firms' shareholders. Empirical findings reveal mixed outcomes: Sun Pharma’s acquisition of Ranbaxy led to a 9.8% share price increase within five days, while Tata Steel’s high-premium acquisition of Bhushan Steel saw only a 1.7% gain. In contrast, deals like Reliance–Future Retail and Tata Power–Welspun Power showed minimal or negative returns, despite sizable premiums. These patterns indicate that premium size alone is not a reliable predictor of post-deal shareholder wealth creation. The study concludes that M&A success depends more on strategic fit, market timing, and sectoral dynamics than on the premium offered. This analysis contributes to the broader M&A discourse by offering evidence-based insights into how premium valuations can either maximise or dilute shareholder value, aiding investors, corporate strategists, and policy analysts in deal assessment.
