Abstract

PT. ABC, as a contractor engaged in renovation work, faces several operational constraints. This study focuses on determining the priority sequence of renovation project risks using the Analytical Hierarchy Process (AHP) approach. Data collection was conducted through interviews and distributed pairwise comparison questionnaires to experts. From the identification process, ten types of risks deemed critical were recorded. Based on AHP processing, the top three risks requiring attention are Inaccurate Budget Planning (33.12%), Surge in Material Prices (16.94%), and Errors in Material Specifications (14.42%). The Consistency Ratio (CR) value of 0.040 indicates that the assessments provided are consistent. The implication of this study emphasizes financial and technical-material aspects as the most urgent areas requiring immediate attention. The proposed recommendations include improving the cost estimation system and strengthening material supply governance. The results of this study are expected to serve as a reference in formulating mitigation strategies and resource allocation more effectively.

Abstract

This study aims to evaluate the work system in the PT. Mulia Multi Medika warehouse using an integrative approach of Macroergonomic Analysis and Design (MEAD) and Macroergonomic Analysis of Structure (MAS). The method stages include: (1) identification of the environment and organizational structure; (2) definition of the work system through SWOT analysis; (3) setting performance expectations and mapping subsystems; (4) ergonomic risk assessment using the Workplace Ergonomic Risk Assessment (WERA) and Job Strain Index (JSI); and (5) analysis of the work environment in the form of temperature and noise. In addition, interviews with managers and workers were conducted to capture subjective perceptions of workload and system effectiveness. The results show that worker 1 has a WERA score of 41 (moderate risk) and a JSI of 18 (high), while worker 2 has a WERA score of 35 (moderate) and a JSI of 6.75 (low). The temperature of 18–22°C and noise of 68–72 dB are still within safe limits. The MEAD–MAS analysis revealed role imbalances and technological limitations. Recommendations for improvement include the use of material handling aids, role redistribution, and continuous evaluation to reduce ergonomic risks while increasing productivity.

Abstract

Musculoskeletal Disorders adalah salah satu cedera yang sering dialami pekerja dalam melakukan kegiatan Material Handling yaitu cedera pada otot, syaraf, tulang, persendian, tulang  rawan yang disebabkan oleh aktivitas kerja. PT. AFS merupakan sebuah perusahaan yang berfokus pada bidang jasa boga untuk melayani kebutuhan “airlines catering” dan untuk kebutuhan perusahaan-perusahaan di Makassar. Gudang sebagai tempat penyimpanan bahan baku yang akan terus beroperasi di setiap harinya. Selain karena proses produksi akan terus terhubung ke gudang, juga karena bahan baku yang terus masuk menyebabkan operator akan terus bekerja untuk mengatur bahan baku sebagai persediaan produksi. Pekerjaan operator dalam proses pemindahan barang di gudang selain menggunakan cara manual, juga menggunakan alat bantu untuk memindahkan bahan baku yaitu hand stacker. Penggunaan alat bantu ini membuat operator harus dibantu oleh operator lainnya untuk menarik hand stacker baik dalam kondisi ada atau tidak ada bahan baku yang akan dipindahkan. Berdasarkan kuisioner Nordic Body Maps, keluhan sakit yang paling tinggi adalah pada bagian leher bawah, bahu kiri dan bahu kanan. Kondisi ini berbahaya bagi operator seperti yang ditunjukkan oleh hasil Rapid Upper Limb Assesment  (skor 7) dengan level kategori 4 (kondisi ini berbahaya dan diperlukan untuk melakukan perubahan dengan segera saat itu juga).

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

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.
