Abstract

Tarzan photo is a photography company operating in the photo studio on Jl.KH. Hasyim Ashari, Gambir Jakarta, the center of the problem with this photo company is the route that consumers take and less efficient service which causes chaos on the route and this photo company has not been able to meet demand optimally. the layout is still not quite right, where to transfer materialsbetween departments, the distance required is quite far so it takes quite a long time. Apart from that, this causes the flow of service to become irregular and the relationship between departmentsto be less effective, such as the location of the traffic room being too far from the sales room. Giventhese existing problems, research was carried out using the Activity Relation Chart (ARC) methodwith the hope of minimizing the length of the material and consumer paths, indirectly shortening the traffic distance in handling photo services and gaining customer satisfaction. The results of the layout design obtained that the distance length in the initial conditions was 166 m, while the length of the track distance in the proposed conditions was 119 m. This means that when designing the proposed layout conditions using the Activity Relation Chart (ARC) method, the length of the track distance can be minimized by 47 m, from the initial conditions.

Abstract

Occupational Health and Safety (OHS) is a crucial aspect in creating a safe and productive environment. Occupational Health and Safety (OHS) issues have traditionally focused on the industrial sector, yet schools, as venues for educational processes, also pose potential hazards that can threaten the health and safety of students. This study aims to analyze potential hazards in elementary schools using the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method. The study was conducted at MI Tazkirunnas, East Jakarta, using a quantitative descriptive approach. Data were collected through observation, interviews, and documentation of school activities and facilities. The analysis showed that 56% of areas/activities were categorized as medium risk, 25% as high risk, and 19% as low risk. The most common hazards included poorly maintained electrical installations, slippery floors, unsafe sports facilities, and the lack of emergency evacuation routes. Recommendations for control include improving physical facilities, implementing OHS SOPs, providing safety signs, and training teachers and students. These findings demonstrate the importance of implementing OHS early in schools to build a safety culture and prevent accidents.

Abstract

This study aims to identify potential failure modes caused by earthquake hazards at PT KMI Indonesia’s production facilities and to establish disaster mitigation priorities through the integration of Failure Mode and Effects Analysis (FMEA) and Analytical Hierarchy Process (AHP). This approach bridges technical risk assessment and organizational preparedness within the metal industry context. Data were collected through interviews, field observations, and AHP questionnaires from 287 respondents. The FMEA results revealed three critical risks: gas leakage, inaudible alarms, and electrical hazard vulnerability. The AHP analysis prioritized regulatory compliance, early warning and monitoring systems, and human resource competency as the main mitigation criteria. The integration of FMEA and AHP proved effective in producing an objective and data-driven hierarchy of mitigation priorities. Practically, the study recommends improving evacuation facilities, establishing trained emergency response teams, and implementing digital dissemination of safety procedures to enhance industrial resilience against disasters.

Abstract

This study examines the effect of Lean Manufacturing and Total Productive Maintenance (TPM) on Production Efficiency in manufacturing industries in Cikarang, Indonesia. Increasing competitive pressure in the manufacturing sector requires companies to reduce waste, minimize equipment downtime, and optimize the utilization of production resources. A quantitative explanatory research design was employed, with data collected through structured questionnaires using a five-point Likert scale. Respondents were selected from manufacturing companies operating in the Cikarang industrial area using purposive sampling. Lean Manufacturing was measured through waste elimination, continuous improvement, 5S, standardized work, and production-flow improvement, while TPM was assessed through autonomous maintenance, planned maintenance, preventive maintenance, equipment inspection, and employee involvement. Production Efficiency was evaluated based on production time, waste reduction, machine downtime, resource utilization, production costs, and output improvement. Data were analyzed using multiple linear regression. The findings indicate that Lean Manufacturing has a positive and significant effect on Production Efficiency. Total Productive Maintenance also has a positive and significant effect on Production Efficiency. Furthermore, both variables simultaneously contribute significantly to improving Production Efficiency. These findings suggest that integrating lean practices with effective maintenance strategies can reduce operational losses, improve equipment reliability, optimize resource utilization, and strengthen manufacturing competitiveness.
