Abstract

With the growth of the economy and market demand, Micro, Small and Medium Enterprises (MSMEs) play a significant role in economic development by providing employment opportunities and enhancing local economic growth, typically through small-scale production by artisans and small producers. UMKM XYZ is a small-scale service business specializing in motorcycle shock absorber repairs, employing three workers. In this workshop, issues related to workers' postures were identified, which caused discomfort and potential health problems. The Rapid Entire Body Assessment (REBA) method was utilized to evaluate the workers' body posture, including the positions of the neck, back, arms, wrists, and legs. Consequently, sample data were collected and analyzed to implement improvements in the shock absorber repair process. An assistive tool was designed as a proposed solution to improve workers' postures to be more ideal, resulting in lower REBA scores.

Abstract

The warehouse has a very important role in the supply chain network to distribute products to consumers. PT XYZ warehouse uses a rack system to store products before they are distributed to the production process. The problem faced is that the placement of products is scattered and irregular depending on the conditions in the field, products that come are placed in empty places which can cause the storage space to become larger so that the warehouse capacity has not been fully utilized with a utilization rate of 105% and causes a decrease in the actual warehouse capacity. It’s necessary to rearrange the placement of products in the storage location to optimize the utilization rate of storage space, with the dedicated storage method.  This method is to solve the problems that occur in the warehouse layout which includes product placement in the warehouse by placing only one type of product in one storage room. In this method, products will be stored in a fixed location so that product storage is more organized. The results of the application of the dedicated storage method obtained a storage space utilization rate of 100%, while in the existing condition it was 105% with a percentage decrease of 5%.

Abstract

Waktu setup yang lama pada proses injection molding dapat menyebabkan downtime yang signifikan, mengurangi produktivitas, dan meningkatkan biaya produksi. Penelitian ini bertujuan untuk mengurangi waktu setup mold pada mesin berkapasitas 450 ton di PT MWT dengan menerapkan metode Single Minute Exchange of Dies (SMED). Metode ini diterapkan dengan mengidentifikasi dan mengonversi aktivitas internal menjadi eksternal serta menyederhanakan langkah-langkah aktivitas internal. Hasil penelitian menunjukkan bahwa waktu setup berhasil dikurangi dari 196 menit menjadi 156 menit, menghasilkan pengurangan waktu sebesar 20,4%. Selain itu, biaya produksi harian berkurang sebesar Rp333.333 atau sekitar 20,4% dari total biaya sebelum perbaikan. Peningkatan efisiensi waktu memungkinkan perusahaan untuk meningkatkan kapasitas produksinya tanpa menambah sumber daya. Penerapan metode SMED juga berdampak positif pada kualitas produk, dengan risiko produk cacat yang lebih rendah karena proses setup yang lebih cepat dan terstandardisasi. Penelitian ini menunjukkan bahwa metode SMED merupakan langkah efektif dalam meningkatkan efisiensi dan daya saing perusahaan di industri manufaktur.
