Abstract

This study evaluates the effectiveness of the Rapid Upper Limb Assessment (RULA) method in improving work posture in industrial settings. Poor posture can lead to musculoskeletal disorders and reduced productivity. Using a quantitative approach, RULA was applied across several production departments, with data collected through direct field observation. The analysis shows that RULA significantly improved work posture, reduced discomfort, and lowered the risk of musculoskeletal injuries. The study supports RULA as an effective tool for posture improvement and recommends integrating regular ergonomic evaluations into work design.

Abstract

A firm called CV. Sulis Keramik makes parts for mosquito mats; these parts come in the shape of PTC heating elements. A kind of positive temperature coefficient thermistor used in heating applications is the ptc heating element. There are still many different waste indicators throughout the production process, which lowers the process's efficacy and efficiency. Defects with a 10% defect rate are among the main issues. Furthermore, there exist other indicators of waste associated with waiting times, transportation, and other wastes. With the use of lean manufacturing techniques, this project seeks to eradicate waste from CV Sulis Keramik ptc heating element production process. Value stream mapping in its current state, waste assessment models, value stream analysis tools, production system improvement, and designing future value stream mapping were all shown in the research's first stage.

Abstract

The average number of patients served by the Grogol Health Center in the general polyclinic is 40 to 45 patients every day. Based on these data, there is a buildup of 7-10 patients, with an average service time of 10 minutes per patient. From the results of further observations, there is a buildup of patients in the general polyclinic of the Grogol Health Center. This study aims to solve the queue problem with the line balancing method and develop an online registration application at the Grogol Health Center that can increase the efficiency of the patient registration process and reduce waiting time. Line Balancing is a method for solving queue system problems. So that the results of this study are the creation of an integrated application and online registration that can reduce waiting time

Abstract

This study aims to identify the most suitable public transportation mode in Surakarta to support sustainable urban mobility by applying the Complex Proportional Assessment (COPRAS) method. The research considers six evaluation criteria, namely convenient user, user safety, accessibility and inclusivity, fee, time efficiency, and mobility, which reflect both service quality and efficiency aspects of urban transportation. The alternatives assessed include Batik Solo Trans (BST), van, pedicab, taxi and taxibike (online and manual), representing the main public transport modes available in the city. The methodology involves normalizing the decision matrix, applying the assigned weights to the criteria, and calculating the positive and negative significance values for each alternative, followed by determining their relative significance and utility values. The findings indicate that among the alternatives, van with 100,00 achieved the highest utility value, making it the most appropriate choice for enhancing public transportation services in Surakarta. The results demonstrate that the COPRAS methos provides a systematic and balanced approach for integrating benefit and cost criteria, offering practical insights for policymakers in developing to promote efficient, inclusive, and sustainable urban transportation systems

Abstract

Machine maintenance and repair are essential to maintain optimal machine performance. Downtime is a situation where damage occurs to a machine component or when the machine restarts after undergoing a repair or replacement process. CV Madyotomo is a printing company that experienced a total of 20,114 minutes of machine downtime, resulting in a financial loss of Rp 50,285,550. This study aims to design a maintenance system on the Müller Martini 321 stitching machine at CV Madyotomo using the Reliability Centered Maintenance (RCM) approach. The results of the Failure Mode and Effect Analysis (FMEA) analysis show four critical components, namely bearing (RPN 240), v-belt (RPN 189), shaft gear (RPN 175), and support gear (RPN 160). The critical components are bearing, v-belt, shaft gear, and support gear. The application of the RCM method and the integration of the 5R concept has been proven to minimize downtime, extend the life of critical components, and increase the efficiency of the production process

Abstract

Circular design offers significant potential for creating more environmentally friendly and sustainable machines. However, its implementation also presents a number of challenges, particularly related to operational safety and sustainability evaluation. A comprehensive evaluation approach and clear technical standards are needed to ensure that circularly designed machines remain efficient, safe, and suitable for long-term use. This research method uses a literature review to develop indicators. The results of this article identify 16 indicators that can be used to develop sustainable machine designs. These indicators are divided into two main categories: 8 indicators related to environmental aspects, including energy savings, recycling, reuse, toxic and hazardous materials, number of components, product durability, and environmentally friendly components; and 9 indicators related to technical aspects, including assembly and disassembly, product dimensions, product weight, maintenance, safety of use, ease of operation, ease of cleaning, ease of production, and product adaptability. Furthermore, indicator validation is crucial to ensure that the indicators used are relevant, accurate, and reliable in the context of developing sustainable machine designs.

Abstract

Project delays have a substantial impact on overall implementation performance; therefore, effective control and scheduling mechanisms are essential to ensure time efficiency throughout every phase of work. CV. Kharisma Karya Nusantara frequently encounters delays caused by excessive overtime and an unstructured reporting system that cannot be evaluated in real time. This study aims to design a project management system and analyze the scheduling impact using the Critical Path Method (CPM). The CPM analysis identified a critical path consisting of preparatory work, lower structure levels 1 to 3, ground floor work, upper structure levels 1 and 2, first, second, and third floor structural works, walls and partitions of the second floor, first floor finishing, and final work. The total project duration calculated using CPM was 588 days. When recalculated using Microsoft Project, the duration was reduced to 337 days, resulting in a time efficiency of 251 days. These findings demonstrate that implementing a well-structured and integrated project management system can significantly enhance scheduling efficiency, minimize delays, and optimize overall resource utilization.

Abstract

Service is an important aspect for the service industry, including hospitals, one of the important aspects in a service is the queue. Siaga Medika Banyumas Hospital provides services with 3 doctors and there are 4 main services at Siaga Medika Banyumas Hospital, namely, registration, doctor services, payment and taking medicine. This research carries out queue simulations using flexsim and line balancing calculations. The results show that the line balancing calculation in the initial state has an average path efficiency of 64.90% with simulation results of 31 patients queuing. calculations after line balancing showed an average path efficiency of 87.17% with simulation results of 37 patients queuing. The alternative of adding 1 new doctor obtained an average path efficiency of 78.80% and made a difference in the number of queues for doctor services to 14 patients.
