Abstract

Competition in the manufacturing industry requires companies to improve operational effectiveness, particularly in inventory management. PT XYZ, which initially operated in the metal fabrication services sector, has expanded into manufacturing; however, during this transition, inventory was still recorded manually, leading to data discrepancies and operational issues. Observations from a stocktaking process conducted in June 2025 indicated that inventory accuracy was only 76%, resulting in delivery delays, inventory accumulation, and potential financial losses. This study aims to design and implement an AppSheet-based inventory management system to address these problems. The system was developed using the SDLC method with RAD approach, emphasizing rapid development and user involvement. The developed system includes features for recording incoming goods, outgoing goods, production output, and real-time stock monitoring. System functionality was verified through black-box testing, while system acceptance was evaluated using User Acceptance Testing and a user satisfaction survey. The results indicate that all system functions operated as expected and met user requirements, achieving an average user satisfaction score of 4,25. Although the evaluation of long-term improvements in inventory accuracy remains limited, the system is considered reliable and suitable for daily operational use. It is expected to improve the consistency of inventory data. Keywords: Inventory Management System, AppSheet, RAD

Abstract

Penelitian ini bertujuan untuk menganalisis fenomena waste of knowledge yang terjadi dalam aktivitas pergudangan. Penelitian ini menggunakan pendekatan deskriptif kualitatif dengan objek penelitian berupa Gudang Hotel XYZ. Populasi penelitian mencakup keseluruhan proses operasional gudang, sementara sampel difokuskan pada aktivitas picking sebagai proses yang memiliki potensi kesalahan tertinggi. Pengumpulan data dilakukan melalui observasi langsung dan wawancara informal, kemudian dianalisis menggunakan metode analisis tematik untuk mengidentifikasi pola permasalahan yang muncul. Hasil kajian menunjukkan bahwa waste of knowledge dipicu oleh dua masalah utama, yaitu ketiadaan dokumentasi yang jelas terkait tata letak dan penyimpanan barang, serta tidak adanya mekanisme transfer knowledge yang sistematis antar staf. Kondisi tersebut menyebabkan berbagai inefisiensi operasional, seperti meningkatnya waktu tunggu akibat proses pencarian barang yang memerlukan waktu lebih lama, serta meningkatnya potensi kekeliruan dalam pengambilan barang karena adanya kemiripan penamaan pada beberapa barang. Temuan ini mengindikasikan perlunya pengembangan sistem dokumentasi dan prosedur pelatihan yang lebih terstruktur untuk meningkatkan efektivitas operasional gudang.

Abstract

This study aims to identify operational waste based on the Seven Waste approach and to propose improvement strategies through the implementation of the 5S method in a retail business. The study employs a case study approach conducted at Koperasi UB, which operates with limited space where storage and product display areas are combined. The research methods include waste identification using the Seven Waste framework, root cause analysis through the 5 Whys method, and the formulation of improvement proposals using the 5S methodology. The results indicate that the dominant wastes are inventory waste, motion waste, and defect waste, caused by overstock conditions, ineffective layout, and the absence of standardized operational guidelines and demand forecasting. The proposed improvements focus on workspace arrangement, storage standardization, and the development of work discipline to enhance operational efficiency and minimize waste.
