Abstract

TB. Medang Indah is a building materials store located in Medang, Tangerang Regency, Banten which has been established since 2008. This study aims to obtain optimal transportation costs with an effective route in distributing cement to TB. Medang Indah. To achieve the objectives of this research, several steps were carried out, namely, by creating a transportation model from the data obtained, determining the initial solution using the Vogel's Approximation (VAM) method, and determining the optimal solution using two methods, namely the Stepping Stone method and the Modified Distribution (MODI) method. From determining the initial solution of Rp. 52,460,000.00 and the optimal solution from both methods has the same cost and route, which is Rp. 52,350,000.00. This indicates that the route to be used by TB. Medang Indah in optimizing costs with efficient routes, namely Rp. 52,350,000.00.

Abstract

Selecting the right wood Supplier is a critical factor in ensuring smooth production processes and maintaining the quality of raw materials used by a company. Mistakes in Supplier selection can lead to production delays, increased costs, and a decline in final product quality. Therefore, this study aims to determine the best wood Supplier using a Multi-Criteria Decision Making (MCDM) approach. This research employs a descriptive quantitative approach involving four alternative Suppliers and seven evaluation criteria: wood price, wood quality, delivery punctuality, Supplier distance, supply capacity, payment system, and Supplier reputation. Data were collected through structured interviews with company decision makers and a review of relevant internal documents. The analytical methods used are Weighted Product (WP) and the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) to rank Suppliers based on the established criteria. The results indicate a difference in Supplier rankings between the two methods due to differing calculation approaches and evaluation concepts. The WP method emphasizes the consistency of Supplier performance across all criteria, while the TOPSIS method assesses the proximity of an alternative to the ideal solution. Based on the analysis, the Weighted Product method is considered more appropriate and is recommended for determining the best wood Supplier for the company.

Abstract

This study aims to evaluate the performance of packaging suppliers used by Nasi Tempong Nyonya as a crucial component of operational effectiveness in the fast-food industry. Packaging suppliers play a strategic role in supporting daily operations, as packaging quality directly affects food safety, product presentation, brand image, and overall customer satisfaction. Therefore, systematic supplier evaluation is required to ensure consistent material quality, price stability, timely delivery, and reliability of supply in meeting operational demands. Preliminary observations reveal several challenges in the procurement of packaging materials, including frequent price fluctuations, inconsistent material quality, limited use of environmentally friendly packaging, and suboptimal supplier responsiveness to sudden changes in demand volume. These issues have the potential to disrupt operational workflows and reduce service consistency. To address these concerns, this research adopts an evaluative approach by analyzing key supplier performance indicators, direct operational observations, and assessments aligned with the company’s operational needs and standards. The findings indicate that the current packaging supplier has not fully met Nasi Tempong Nyonya’s operational expectations, particularly in terms of material quality consistency and delivery timeliness. These shortcomings highlight the importance of implementing a more structured and objective supplier evaluation system. Such a system can serve as a strategic basis for performance improvement initiatives, strengthening long-term supplier relationships, or considering alternative suppliers. Ultimately, this study is expected to provide practical insights to enhance operational efficiency and maintain consistent service quality for customers.
