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

In Surakarta City, high mobility is shown by 2023 vehicle registration data, where passenger cars and motorcycles made up 95,19% of all vehicles, while public transport units numbered only 354. In 2024, the city’s economy grew by 5,61%, led by the Information and Communication sector. However, transportation did not contribute significantly, even though efficient public transport is crucial for sustainable urban growth. This study aims to recommend suitable public transportation modes for Surakarta that address mobility challenges and support integrates transportation ergonomics focusing on convenient, safety, accessibility and inclusivity into the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method to evaluate alternatives. Using a validated and reliable questionnaire distributed through purposive sampling, the study assessed several modes. The TOPSIS results show closeness coefficients of 0,847 for Batik Solo Trans (BST), 0,649 for taxis and motorcycle taxis, 0,593 for feeder minibuses, and 0,152 for pedicabs. BST emerged as the most suitable mode, offering potential to enhance mobility, streamline logistics, and attract investment. The findings highlight the importance of ergonomics-based transport policies that improve user experience and encourage a shift from private to public transportation, strengthening Surakarta’s economic resilience.

Abstract

This study intends to create a system for maintenance and a schedule for preventive maintenance for the sewing machine at CV Madyotomo by utilizing the Reliability Centered Maintenance (RCM) approach. The main problem is the high downtime of the Müller Martini 321 stitching machine, which reached 20,114 minutes during January–June 2025, resulting in a production capacity loss of 1,005,711 books and an estimated financial loss of around Rp50,285,550. The research method involved identifying critical components through observation, interviews, and Failure Mode and Effect Analysis (FMEA), followed by the calculation of Mean Time To Failure (MTTF), Mean Time To Repair (MTTR), and failure distribution using Minitab 19 software. The results indicate four critical components with the highest Risk Priority Number (RPN), namely bearing (240), v-belt (189), shaft gear (175), and support gear (160). Based on the analysis, the optimal preventive maintenance intervals are bearing every 18 days, v-belt every 21 days, shaft gear every 21 days, and support gear every 28 days, with MTTF values ranging from 693 to 1,174 hours and MTTR averaging 4–6 hours. The implementation of an RCM-based preventive maintenance strategy is proven to reduce downtime, improve machine reliability, and ensure production efficiency, thus providing a guideline for printing companies in formulating measurable, effective, and efficient maintenance policies.
