Abstract

Total Productive Maintenance (TPM) was introduced by Seiichi Nakajima in Japan in the 1950s, inspired by the concept of Preventive Maintenance by George Smith from the United States. The initial implementation of TPM was carried out by Nippondenso, a Toyota supplier, in the 1960s, with the result of increased productivity and reduced equipment downtime. TPM evolved into a global management system that focuses on eight pillars to achieve production efficiency, reduced maintenance costs, and improved product quality. TPM has been adopted by various industries, especially Manufacturing. One of the key indicators in TPM is Overall Equipment Effectiveness (OEE), which measures availability, performance, and quality. The OEE value is influenced by six main factors (Six Big Losses), but it is not yet known more specifically the biggest problem of six big losses. For this reason, it is necessary to analyse various industrial sectors. The research shows that downtime due to machine failure is the biggest problem in 35 or 83.3% of industrial sectors. Further analysis is needed to improve the effectiveness of machinery and equipment, especially in the automotive sector which is often the focus of research. The results of the review process also have not found research related to equipment effectiveness through OEE measurements in the field of services.

Abstract

This research was conducted at PT XYZ, a tire manufacturing company established in 1988 in Indonesia. The study focuses on the curing tire press machine, which has experienced high downtime issues. The purpose of this research is to analyze Total Productive Maintenance (TPM) using the Overall Equipment Effectiveness (OEE) method and calculate the Six Big Losses on the machine during the period of January to June 2023. Data was collected through observation, interviews, and literature review. The findings show that high breakdown frequency significantly impacted downtime and reduced production effectiveness. The OEE value of the curing tire press machine was 78.22%, which is below the global OEE standard of 85%. The largest factor hindering OEE achievement was Idling and Minor Stoppages, with a value of 21%. The proposed recommendations are expected to reduce downtime and improve machine performance, allowing PT XYZ to meet its production targets.

Abstract

PT XYZ is a company based in logistics services, handling, and port development that recently merged to improve the quality of the company. So there have been many changes, and one of those affected is the head office procurement group. The impact that occurred in the head office procurement group was the formation of the SSC (Shared Service Center) organization. The formation of the SSC resulted in the reassignment of several employees in the procurement group. Therefore, to find out the workload experienced by using Full Time Equivalent (FTE) calculations, this research was undertaken. Based on the calculation of workload with Full Time Equivalent (FTE), The workload experienced is included in the underloaded workload category for all employees because it is in the range 0–0.99. Where the number of permanent employees is 10 and does not experience changes due to workload. Therefore, to overcome the overloaded workload, it is possible to make adjustments to the distribution of work procedures between positions evenly, map the work process by adjusting the balanced specifications and qualifications of employees against the latest organizational structure, and carry out a comparative analysis of psychological workload.

Abstract

PT XYZ is a corporation that deals with natural gas transportation and distribution. PT XYZ, particularly the Project Management Office division in distribution region 2, occasionally encounters challenges during the process, like project delays. The project was delayed because of a lack of people and an unequal workload in carrying out job operations at PT XYZ. As a result, measuring workload as a foundation for determining manpower requirements is essential. The Full Time Equivalent (FTE) approach was employed by the researchers in this investigation. After using this approach, it is determined that the workload in distribution area 2 is imbalanced among the 16 operators operating, with 13 having high workload or overload and 3 having moderate workload (fit). The proposed enhancements include adding 8 operators and performing horizontal mutations; the ideal workforce consists of 24 individuals with workloads in the normal (fit) and low (underload) categories. Based on the cost analysis, the option with the lowest cost was picked, namely expanding a workforce of 8 operators, with additional specifics of the monthly expenditures equal to IDR 117,050,000.-.

Abstract

This study takes a close look at Electric Cars (EVs) and Internal Combustion Engine Vehicles (ICEVs) in Malaysia to discover how they impact energy use, the economy, and the environment. This study is important because Malaysia is still a growing country with its own energy, economic, and environmental problems. It checks out how well Electric Vehicles (EVs) and Internal Combustion Engine Vehicles (ICEVs) work and how much power they need in various driving conditions. It does this by looking at the different types of energy used in Malaysia and how far car’s technology has comes. In terms of money, the study looks at how much both types of cars cost all together. The price of the car, the cost of repairs, the amount of gas used, and the effect of government support are all part of this. The study is mostly about how Electric Vehicles (EVs) and Internal Combustion Engine Vehicles (ICEVs) pollute and what effects they might have on the environment. This is to help Malaysia reach its goal of lowering greenhouse gas pollution. This study uses both data from the Malaysian government and data from other studies done in other countries. Statistics and comparisons are used to help with the study. The people who did the study think that the data will help us learn more about how people in Malaysia really feel about Electric Vehicles (EVs) and Internal Combustion Engine Vehicles (ICEVs). Customers, lawmakers, and people who work in the business will all be able to choose more eco-friendly ways to get around thanks to these results.
