Abstract

Heat exchangers or often called heat exchangers (HE) are widely used in industry. There are many types of heat exchangers, there are fire pipes or water pipes with cross flow or unidirectional flow. Utilizing exhaust gas is an alternative to reduce costs and increase effectiveness so that wasted energy can be utilized as optimally as possible. A generator is one that can produce electrical energy which produces flue gases with a high temperature so that it can be utilized using a heat exchanger. A shell and tube heat exchanger with a fire tube type was designed. The number of pipes designed was 131 with a pipe diameter of 2.5 inches. The design results obtained from heating water are steam with a capacity of 1 ton. The dimensions of the heat exchanger are 3 meters long with a diameter of 2 meters. The heat energy produced by steam is 2852.2605KW, with a steam temperature produced of 2000C. The resulting LMTD is 360.50K. With this heat exchanger, it is hoped that the costs for producing bias steam will be as minimal as possible

Abstract

This research analyzes the implementation of the Occupational Health and Safety Management System (OHSMS) at PT. KHE Benua Sentosa, comparing it to the standards established in Indonesia’s Government Regulation No. 50 of 2012. Recognizing the critical role of occupational health and safety (OHS) in promoting a safe work environment and enhancing productivity, this study investigates PT. KHE Benua Sentosa’s adherence to regulatory requirements, focusing on policies, planning, implementation, monitoring, and review mechanisms. Employing a qualitative approach with document analysis, the study evaluates the effectiveness of OHS policies at PT. KHE Benua Sentosa based on company documentation. The results reveal that PT. KHE Benua Sentosa has effectively implemented OHSMS standards in line with PP No. 50 of 2012. Key areas of compliance include risk assessment, regular training, performance audits, and continuous improvements, demonstrating the company’s commitment to regulatory standards and worker safety. These findings highlight the alignment between PT. KHE Benua Sentosa’s practices and national OHS standards, contributing to the broader discourse on effective OHS management in the construction sector.

Abstract

This study aims to examine the effect of price, quality and service variables on customer satisfaction in Sumberjaya coffee shops. This research uses a survey-based quantitative approach involving 30 respondents selected using purposive sampling method. Primary data was obtained through an open-ended questionnaire that had been tested for validity and reliability to ensure the accuracy and consistency of the measuring instrument. Data processing was carried out using multiple linear regression analysis to evaluate the relationship between the independent variables of price, quality and service with the dependent variable of customer satisfaction. The results showed that all items in the questionnaire were valid and the research instrument was reliable. Statistically, the variables, price, and service have a significant effect on customer satisfaction, both individually and simultaneously. The findings provide practical implications for coffee shop managers in Sumberjaya to focus on improving these three elements to increase overall customer satisfaction.

Abstract

This study aims to design an ergonomic study table based on students' anthropometric data to reduce the risk of musculoskeletal injuries. Anthropometric data, such as sitting elbow height, knee height, thigh length, and hand reach, were collected from 121 students using an anthropometer. In addition, musculoskeletal complaints were evaluated using the Nordic Body Map (NBM). Ergonomic risks were assessed using REBA (Rapid Entire Body Assessment) and RULA (Rapid Upper Limb Assessment) methods to identify non-ideal work postures. The results of the analysis showed that the current working posture of the students was in the high to very high risk zone, with a final REBA score of 9 and RULA of 8. Based on these results, an ergonomic study table was designed with adjustable height features (60-72 cm), 62 cm table width, and 124 cm table length. This design refers to anthropometric data with the 5th to 95th percentile range to ensure comfort and compatibility with various student body dimensions. This ergonomic study table design is expected to reduce the risk of musculoskeletal injuries, increase productivity, and create a healthier and more comfortable learning environment for students. Design validation through hands-on testing is a recommendation for further research.
