Abstract

This study highlights the problem of managing teak wood raw materials in the form of boards at UD Gemilang, Gunungsitoli City. The company often experiences shortages or excess inventory due to a conventional ordering system that is not based on optimal demand calculations. This inefficiency causes wasteful costs and disrupts the smooth production process. The main objective of this study is to analyze current inventory management and apply the EOQ (Economic Order Quantity) method to determine the optimal order quantity, as well as evaluate its impact on cost efficiency and production operations. The EOQ method is expected to be a systematic and rational solution for managing inventory more efficiently. This study uses a descriptive quantitative approach. Data were collected through direct interviews with business owners and documentation of raw material purchasing and usage reports for 2024. The analysis was conducted using the EOQ formula to calculate the optimal order quantity, ordering costs, storage costs, safety stock, reorder point, and total inventory cost (TIC). The analysis results show that the optimal order quantity for teak wood raw materials is 282 boards, with an ordering frequency of 6 times a year. This number is more efficient than the actual ordering system which is carried out monthly without a fixed calculation. The recommended safety stock is 22 boards, with a Reorder Point (ROP) of 36 boards. The implementation of the EOQ method successfully reduced total inventory costs from Rp6,768,000 to Rp3,496,800.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh persaingan harga terhadap penjualan barang mainan di Toko Selyn Toys serta seberapa besar pengaruhnya. Metode penelitian yang digunakan adalah kuantitatif dengan penyebaran kuesioner kepada 83 responden, dan data dianalisis menggunakan IBM SPSS versi 26. Hasil penelitian menunjukkan bahwa persaingan harga berpengaruh positif dan signifikan terhadap penjualan, dibuktikan dengan persamaan regresi Y = 25,174 + 0,343X. Nilai t-hitung (6,028) > t-tabel (1,989) dengan signifikansi 0,000 < 0,05, yang berarti Ha diterima dan Ho ditolak. Nilai koefisien determinasi (R²) sebesar 0,410 menunjukkan bahwa 41% variasi penjualan dipengaruhi oleh persaingan harga, sedangkan 59% dipengaruhi oleh faktor lain. Nilai koefisien korelasi (0,556) menunjukkan hubungan positif dengan kekuatan sedang. Dengan demikian, semakin kompetitif harga yang diterapkan, semakin tinggi penjualan Toko Selyn Toys.

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.

Abstract

The fast food industry continues to grow as the public's need for practical products, including Kamumu Kimpul chips, increases. However, small business actors such as UD. Sona in Gunungsitoli Idanoi faces obstacles in production due to the use of traditional methods, limited equipment, and lack of optimal management. This condition has an impact on delays in meeting demand, increasing production costs, and declining competitiveness. Therefore, a production optimization strategy is needed to improve product capacity, efficiency, and quality. This study aims to analyze the production optimization strategy implemented by UD. Sona, formulate a capacity building strategy, as well as identify obstacles and solutions that can be done. The results of the research are expected to be practically useful for business actors in production management, as well as make a theoretical contribution to the development of production management science in MSMEs. The research method uses a descriptive qualitative approach. Data was obtained through interviews with owners, employees, and customers, supplemented by observation and documentation. Data analysis is carried out through reduction, presentation, and inductive conclusions, so as to be able to describe the real conditions of the business and develop the right optimization strategy. The results of the study show that UD. Sona has made efforts such as setting up production flows and scheduling planning. However, limited machinery, unstable supply of raw materials, and marketing that has not been maximized are still obstacles. Consumers rate the product as good quality, but its availability has not been consistent. Suggested strategies include the implementation of lean production, improvement of inventory management, and the use of production technology

Abstract

This study aims to analyze the application of the time series method using the Moving Average approach to forecast raw material requirements at UD. Tunas Baru, Gunungsitoli City. The company has traditionally managed its inventory without a systematic calculation basis, resulting in fluctuating purchases and usage that cause overstock and shortages. This research employed a descriptive quantitative method using data on wood board purchases and usage from January to December 2024.The results show that the Moving Average (3-period) method provides a general overview of raw material demand trends, although it remains less accurate in capturing sharp fluctuations. The Mean Squared Error (MSE) value was 27,338 (sheets²), indicating a relatively high deviation between actual and forecasted values.These findings suggest that time series-based forecasting can serve as a preliminary foundation for raw material planning at UD. Tunas Baru. Applying an appropriate forecasting method can help the company minimize inventory imbalance risks and improve production efficiency. It is recommended that the company implement a data-based inventory management system and consider more adaptive forecasting methods such as Weighted Moving Average or Exponential Smoothing.
