Abstract

Distribution is one of the important aspects in the supply chain that plays a major role in the operational cost efficiency of a company. This study aims to optimise the distribution costs of tofu and tempeh from the Apo Gudang Factory to several destination markets in Jayapura using the North West Corner (NWC) method. This method was selected due to its simplicity in providing an initial solution to distribution problems involving the allocation of shipments from two warehouses to four market locations, considering supply capacity, demand, and transportation costs per unit. The study was conducted using a descriptive quantitative approach with primary data obtained directly from the factory in May 2025. The research stages included field observations, transportation table compilation, application of the NWC method, distribution cost calculations, and analysis of results. The results of the study indicate that daily distribution costs can be reduced from IDR15,000 to IDR 400,000, resulting in an efficiency of IDR 15,000 per day. Although the solution from the NWC method may not be globally optimal, it can serve as a basis for further improvements using optimisation methods such as MODI or Stepping Stone. Thus, the application of the NWC method in the distribution of tofu and tempeh factories has proven to provide a systematic and efficient initial solution. This study provides a concrete example that a mathematical approach in distribution management can help companies reduce operational costs and improve the effectiveness of logistics strategies.

Abstract

Clothing is a basic human necessity that continues to evolve with changing trends and lifestyles. One of the emerging trends today is thrifting, which refers to the buying and selling of second-hand clothing, increasingly popular among teenagers. OneTrif is a thrifting clothing sales platform based in Jayapura, Papua, designed to provide easier access for the community to branded clothing at affordable prices. However, its management faces several challenges, such as manual sales processes, difficulties in stock management, and a lack of transparency in transaction recording. To address these issues, a thrifting sales information system has been developed using the Waterfall methodology, which includes requirement analysis, system design, implementation, testing, and maintenance phases. The system design is structured using context diagrams, hierarchical diagrams, overview diagrams, and Entity Relationship Diagram (ERD) to ensure a clear and efficient process flow. The results of this study are expected to provide an optimal solution for OneTrif in managing transactions, speeding up sales processes, and enhancing user experience in digital thrifting shopping.

Abstract

In the digital era, the use of information technology is the main need to improve administrative efficiency in various sectors, including higher education. Universitas Sepuluh Nopember (USN) Papua faces obstacles in the process of admitting new students which are still carried out manually, causing various problems such as inefficiency, risk of data errors, and limited information. To overcome this, this study aims to design a new student admission information system using the Unified Modeling Language (UML) approach that is able to describe the system visually, structured, and easy to understand. The research method used is software engineering with data collection techniques through observation and interviews. The results of the system design are visualized through use case diagrams, activity diagrams, sequence diagrams, and class diagrams to model the process and structure of the system as a whole. It is hoped that the results of this research can provide information system solutions that are more effective, efficient, and support transparency and accountability in the process of accepting new students in the university environment.
