Abstract

One-fourth of Indonesia's Gross Domestic Product or GDP is from the manufacturing industry sector. Indonesia's government has proactively encouraged companies to increase their production capacity to meet the global demands, leading to strong demand for employees to work harder, affecting the workers' health. Overwork is often associated with fatigue, stress, and various health problems. Moreover, stress due to excessive work is a general problem many industries face and frequently influences workers' performance. Therefore, this research intends to examine the relationship between work stress and workers' performance, particularly in the manufacturing industry in Indonesia. The sample data are collected from ninety-three workers at the staff level across various companies in the manufacturing sector. The relationships between the determining factors and the Employee Productivity are evaluated by using the multivariate regression analysis. At the correlation coefficient of 0.972, we found a statistically strong relationship between the work environment and Stress to the workers' performance. The condition of low performance is attributed to the non-standard working hours and low quality of the relationship between colleagues and their superiors. Finally, the research recommends improved management of workers' stress by companies involving the adoption of flexible working hours and better communication between parties via discussion forums and meetings. Therefore, employees will be more motivated to improve work productivity.

Abstract

In this study an analysis of the patient queuing system will be carried out by developing a queuing system, namely adding aspects of patient registration status and the registration process with a system or machine or through the hospital's web by downloading an application. This study aims to improve the efficiency of patient service management in clinics and develop a patient care management simulation model so that the number of patient rejections and patient waiting time in clinics. Discrete Event Simulation (DES) with ARENA and compare it with manual processes and with applications or machines in the registration process. The results show that patient rejection can be reduced to 1%, and the average patient time to be seen by a doctor is 0.7145 hours. If converted into minutes, each type of patient takes about 10 minutes in the doctor's office.

Abstract

People’s needs of wood toward increase. Along with the development of technology, the woodworking industry exists to balance the fulfilment of human needs of wood and to increase the value added of timber forest resources. The objective of this study is to identify the supply chain configuration and to measure the supply chain performance of the downstream woodworking industry. Metrics validation using the supply chain operation reference (SCOR) framework that is adjust to industry activities through discussions with stakeholders. Performance metrics are weighted using the Analytical Hierarchy Process (AHP). The result of the supply chain performance measurement of the downstream woodworking industry obtains a value 76.21 in the good category indicating that XYZ has achieved the target of 59%. 41% need to improve performance, namely 32% in the Average category, 5% in the Marginal category, and 4% in the Poor category.

Abstract

This study focuses on the problems in the use and maintenance of centrifugal pumps at PT Pupuk Kalimantan Timur (PKT) in Indonesia. This study specifically looks at the 110-J pump, which is critical to the production process as its failure can result in a shut down of the factory. The study analyzes the history card of the pump over the period of 2015 to 2021 and identifies that there have been multiple repairs due to high vibration, shaft bending, and other internal damage caused by differences in throat bushing sizes. The study calculates that the average loss due to these issues is around IDR 122,012,857 annually and that the repair work takes about 5 working days. The study uses quality improvement tools plan, do, check, action (PDCA) identify the problems and formulate improvement efforts to increase the usage period and reduce maintenance costs. This study is important for improving the reliability of the production process and ensuring the availability of urea and NPK fertilizer, particularly in Indonesia. Result of this research is the decrease in the frequency of pump repairs from 3.7 times per year to none and accelerate pump assembly from 5 days to 3 working days.Keywords: Centrifugal pumps, shaft bending, maintenance, quality improvement tools, vibration

Abstract

Utilizing the team to carry out operational vehicle maintenance activities is crucial to maintaining smooth mobility. Well-scheduled maintenance can prevent unexpected problems and minimize disruption to vehicle operations. The problem is that the implementation of operational vehicle maintenance policies is not yet optimal. The aim of this research is to focus on operational vehicles so that use is not disrupted and mobility runs smoothly, maintenance scheduling is needed. Completion of this research method will use the Naïve Bayes and Decision Tree data mining applications. This research produces a comparison of the two data mining applications to determine maintenance performance with an accuracy level of the Naïve Bayes method of 33.33% and a Decision Tree at 75.00%. The results of the best algorithm performance analysis are used as a reference for implementing vehicle maintenance scheduling.
