Abstract

Effective machine maintenance is essential for ensuring production continuity in the fiber cement industry, where high-capacity equipment operates continuously under demanding production conditions. This study analyzes the maintenance performance of cement fiber production machines at PT. Nusantara Building Industries using the Preventive Maintenance Management System (PMMS). An empirical case study approach was employed by collecting data through direct observation, semi-structured interviews, and documentation of maintenance records, PMMS forms, inspection checklists, and downtime reports during the internship period. Machine reliability was evaluated using Mean Time Between Failure (MTBF), Mean Time To Repair (MTTR), Pareto analysis, and Fishbone analysis to identify critical equipment and dominant failure causes. The results indicate substantial variations in operational reliability among production machines, with FS6 and FS7 exhibiting the highest downtime and failure frequencies. Pareto analysis revealed that a limited number of failures contributed to most cumulative downtime, while Fishbone analysis identified machine condition, maintenance methods, human factors, environmental conditions, materials, and measurement practices as the principal causes of recurring failures. Reliability-based preventive maintenance scheduling within the PMMS framework established maintenance intervals according to equipment criticality, enabling more effective maintenance planning and resource allocation. The proposed PMMS approach improves maintenance decision-making, enhances equipment reliability, supports production continuity, and provides a practical framework for data-driven maintenance management in continuous manufacturing systems.

Abstract

Stroke is a non-communicable disease that frequently causes motor impairments, particularly in the arm and elbow, requiring continuous rehabilitation to restore functional movement. Telbowmes is an elbow therapy device designed to support controlled joint-movement exercises; however, its use requires an ergonomic supporting chair and table that accommodate users’ anthropometric characteristics. This study aimed to design and develop an ergonomic, safe, and economically feasible supporting chair and table for the Telbowmes elbow therapy device. The research involved anthropometric data collection followed by adequacy, normality, and uniformity tests, percentile determination, product design, manufacturing analysis, and production-cost evaluation. The results produced an adjustable table-surface height of 60.33–86.07 cm, a table length of 45.6 cm, a table width of 80.1 cm, a chair backrest height of 87.6 cm, and a seat dimension of 66.5 cm. The design integrates anthropometric considerations with structural stability, adjustable mechanisms, safety features, manufacturing requirements, and economic analysis. The manufacturing analysis also established a structured relationship among materials, components, production operations, and assembly activities. The estimated production cost was IDR 3,300,000 per unit, with an estimated selling price of IDR 3,960,000. The developed design provides an integrated ergonomic support system intended to improve user comfort, safety, and compatibility during elbow rehabilitation.
