Abstract

MMP is a metal manufacturing company engaged in casting, forging, and machining processes with a three-shift work system, including night shifts that may increase mental and physical workload due to disruptions in workers’ biological rhythms. This study aims to analyze the mental and physical workload of die casting machine operators during the night shift and to propose improvement measures using the Fault Tree Analysis (FTA) method. The study involved 23 operators, with mental workload assessed using NASA-TLX and physical workload measured using CVL. The results indicate that mental workload falls into high to very high categories, with WWL values ranging from 46.6 to 97.3, where 12 operators experienced very high mental workload. The dominant contributing dimensions were effort, physical demand, and temporal demand. Meanwhile, physical workload ranged from 19.48% to 36.36% CVL, with most operators not experiencing fatigue. Although physical workload remains within acceptable limits, the high mental workload indicates the need for improvements. FTA analysis identified key contributing factors, including work methods, work systems, ergonomics, machine conditions, and the work environment. Proposed improvements include job rotation, improvements in work methods and task distribution, adjustments to the work system, enhanced machine maintenance, and ergonomics-based workplace improvements.

Abstract

Work-Related Musculoskeletal Disorders (WMSDs) represent a major occupational health challenge in small, and medium enterprises (SMEs), particularly in manual material handling (MMH) activities performed without mechanical assistance. This community service study aimed to analyze ergonomic risks and implement ergonomic interventions in MMH activities at TB. XX, a building material store in Kulon Progo. The method applied a multidisciplinary approach involving workplace observation, ergonomic risk identification, assessment of musculoskeletal complaints, standardized posture analysis, managerial engagement to ensure organizational commitment, and ergonomic interventions through proper lifting technique training and simple assistive devices. The results indicated that three workers performed MMH involving loads of 3–30 kg for approximately four hours per day and reported musculoskeletal complaints in the neck, shoulders, lower back, and legs. Ergonomic and participatory interventions are expected to reduce WMSD risks and improve occupational safety, comfort, and productivity in SMEs

Abstract

Tingkat kecacatan produk pada Pabrik Mie Lethek Asli Bendo Cap Garuda masih berada pada kisaran 6–7%, melebihi batas toleransi perusahaan sebesar 5%, sehingga diperlukan analisis untuk mengidentifikasi penyebab dan menentukan prioritas perbaikan. Penelitian ini bertujuan menganalisis risiko kecacatan produk menggunakan metode Failure Mode and Effect Analysis (FMEA) dan Fault Tree Analysis (FTA). Metode FMEA digunakan untuk menentukan prioritas risiko berdasarkan nilai Risk Priority Number (RPN), sedangkan FTA digunakan untuk mengidentifikasi akar penyebab kegagalan. Hasil penelitian menunjukkan bahwa cacat retak atau hancur merupakan jenis kecacatan dominan dengan persentase 53,25%. Nilai RPN tertinggi sebesar 245 ditemukan pada proses pengangkatan akibat penanganan yang kurang hati-hati. Analisis FTA menunjukkan bahwa faktor manusia dan metode kerja, terutama belum adanya standar operasional prosedur (SOP) yang jelas, menjadi penyebab utama kecacatan. Usulan perbaikan meliputi penyusunan dan penerapan SOP, pelatihan operator, peningkatan pengendalian kualitas bahan baku, serta perbaikan kondisi lingkungan produksi. Implementasi usulan tersebut diharapkan dapat menurunkan tingkat kecacatan dan meningkatkan kualitas produk.

Abstract

Inventory management plays a crucial role in supporting operational continuity by ensuring raw material availability while maintaining cost efficiency. UMKM Es Teh Kampoeng Solo utilizes a centralized warehouse to supply raw materials to multiple outlets. Nevertheless, procurement decisions are predominantly based on managerial experience and routine practices, which may lead to excess inventory or stock shortages. This study was conducted to evaluate the effectiveness of three inventory control approaches, namely Economic Order Quantity (EOQ), Periodic Order Quantity (POQ), and Just In Time (JIT), in identifying the most efficient inventory management method. A quantitative case-study design was employed using primary and secondary data obtained through observations, interviews, documentation, and company records from January to April 2026. The materials examined included tea, sugar, cups, ice blocks, 3 kg LPG cylinders, straws, and plastic packaging. The findings indicate that EOQ provides the lowest inventory cost, amounting to Rp1,157,818, compared with the existing system at Rp2,255,782, POQ at Rp5,553,572, and JIT at Rp5,111,040. Furthermore, EOQ reduced inventory expenses by 48.67% relative to the current practice and generated safety stock as well as reorder point values that support more systematic inventory planning. Based on these results, EOQ is considered the most suitable method for inventory control at UMKM Es Teh Kampoeng Solo because it offers the greatest cost efficiency, minimizes stockout risk, and can be implemented more easily than the alternative methods.

Abstract

PT Sinergi Gula Nusantara (PG Pagotan Madiun) merupakan perusahaan yang bergerak dibidang produksi gula, yang berlokasi dijalan raya Ponorogo, Pagotan, Geger, Kota Madiun. Masalah yang ada pada PG Pagotan Madiun pada saat produksi penggilingan masih mengabaikan keselamatan dan Kesehatan kerja yang dimana hal tersebut memungkinkan terjadinya potensi bahaya kecelakaan kerja pada saat proses penggilingan.

Abstract

PT Bakpia Kurnia Sari is one of the producers of bakpia, a traditional food from Yogyakarta. The purpose of this research is to address the problem of high distribution costs in delivering bakpia from the production site to each outlet. Based on data processing, the results show a reduction in total distance from the initial 116 km to 88.6 km using the Saving Matrix method and to 74.7 km using the Nearest Neighbor method, with the proposed routes consisting of 2 routes serving 9 outlets. After determining the new optimal route sequences, the initial monthly distribution cost of IDR 11,438,800 was reduced to IDR 7,900,600 using the Saving Matrix method and to IDR 7,562,600 using the Nearest Neighbor method.
