Abstract

This study identifies and reduces waste in the cooking oil production process at PT X by integrating Lean Six Sigma with Value Stream Analysis Tools (VALSAT) and Failure Mode and Effects Analysis (FMEA). VALSAT is used to classify value-added and non-value-added activities, while FMEA prioritizes waste based on Risk Priority Number (RPN). The results show that defects are the most dominant waste (RPN 294), followed by waiting and inventory. Process mapping reveals a total lead time of 370 minutes, in which 60 minutes are non-value added. Improvement recommendations include scheduling preventive maintenance, aligning raw material orders with actual demand, optimizing operator coordination, applying FIFO in inventory handling, and increasing transportation efficiency. This integrative approach provides a structured method for identifying critical waste sources and supports operational efficiency improvement in food-processing industries.

Abstract

Musculoskeletal Disorders (MSDs) are a prevalent issue among lathe operators in small automotive repair workshops, largely due to repetitive movements, prolonged static positions, and awkward postures. This study employed the Nordic Body Map (NBM) and Workplace Ergonomic Risk Assessment (WERA) to evaluate ergonomic risks and identify affected body areas among lathe operators at XYZ workshop. Results indicate significant discomfort in the lower back, neck, shoulders, and wrists, linked to static postures and repetitive motions required for lathe operations. WERA scores revealed moderate ergonomic risks, particularly involving shoulder posture and work duration. Visual summaries in the form of bar and radar charts illustrate key risk factors. To mitigate these risks, the study proposes low-cost ergonomic interventions such as workstation adjustments, anti-vibration gloves, regular breaks, posture training, and rotational work schedules. These interventions not only address immediate discomfort but also have long-term potential for reducing MSDs when integrated into worker training programs. Moreover, the study’s findings can be utilized as contextual learning materials within applied science education (IPA terapan) at vocational schools (SMK), fostering ergonomic literacy among students and educators.This study fills a significant gap in ergonomic research in informal micro-industry settings and offers actionable insights for both occupational health improvement and science-based curriculum development in vocational education.

Abstract

This study was conducted to determine the level of mental workload experienced by firefighters in Bone Bolango Regency, Gorontalo. The method used was the Rating Scale Mental Effort (RSME), with the research subjects consisting of three work shifts, each containing nine officers. The measurements focused on the level of mental effort required when performing tasks such as standing by, extinguishing fires, rescuing people, and other support tasks that require full attention. The results showed that each shift had a different mental workload score, influenced by incidents, pressure to act quickly, and unpredictable waiting conditions. Overall, the RSME scores indicate that most officers fall into the moderate to high mental load category, especially in activities that require high concentration and quick decisions. These findings show that firefighting work not only relies on physical strength but also requires strong mental preparedness to ensure personal and public safety.

Abstract

Kemajuan industri sepatu di indonesia mendorong pengusaha sepatu kecil maupun besar untuk bersaing dalam segi kualitas, karena konsumen sangat bergantung pada kualitas, sehingga sangat diperlukan pengendalian kualitas yang baik supaya dapat menjadikan konsumen sebagai pelanggan setia. UD. XYZ adalah perusahaan kecil yang memiliki masalah terhadap pengendalian kualitas sehingga sangat memerlukan pengendalian kualitas menggunakan metode SQC. Dan didapatkan hasil bahwa UD. XYZ bahwa data peta kendali P menunjukan tidak ada dari ke 30 titik yang berada diluar batas kendali, sehingga dapat disimpulan bahwa proses terkendali, tetapi UD. XYZ tetap harus meningkatkan kualitas produk dengan mengevaluasi 4 elemen (mesin, manusia, alat, dan metode).

Abstract

Product defects contribute to material waste, delays in delivery, and increased production costs. This study aims to identify the causes of product defects and reduce defect levels in songkok (traditional cap) production at CV PPI using the Seven Tools method and Failure Mode and Effect Analysis (FMEA). Data were collected in August 2025, revealing three main types of defects: untidy stitching (29.47%), inaccurate sizing (32.11%), and velvet surface defects (38.42%). Defect analysis was conducted using Seven Tools, while corrective actions were determined through FMEA by calculating the Risk Priority Number (RPN). The findings show that the highest RPN value was 210 for inaccurate sizing, followed by untidy stitching (RPN 168) and velvet surface defects (RPN 140). Improvement recommendations include stricter supervision during production, periodic evaluation of tools and materials, revision of inadequate Standard Operating Procedures (SOPs), and proper selection of velvet materials that meet quality standards to ensure product consistency and customer satisfaction.

Abstract

Micro-scale tofu industries often operate using conventional production systems that evolve through habit rather than structured technical planning, leading to inefficiencies in energy use and workflow organization. This Community Service program was conducted at UD SDD Kediri to enhance the functional value of its yellow tofu production system through a value engineering approach. The activity focused on improving the combustion system and facility layout without requiring costly technological replacement. The methodology consisted of situational analysis, functional identification, process mapping, simulation of layout improvement, limited implementation, and evaluation. Initial observations showed a production cycle time of approximately 180 minutes per batch, material movement distance of ±22 meters, and high heat exposure due to an uninsulated traditional furnace. Layout simulation reduced movement distance to ±14 meters and shortened movement time from 25 to 15 minutes, indicating a potential efficiency improvement of around 36% in motion-related activities. Minor adjustments in airflow and heat direction improved combustion stability and reduced direct heat exposure. The findings demonstrate that inefficiencies were primarily associated with weak supporting functions rather than production capacity limitations. The program strengthened both technical configuration and managerial awareness of function–cost relationships, confirming that incremental value engineering interventions provide a feasible pathway for efficiency enhancement in micro-scale food enterprises.
