This study is concerned with maintenance on a heavy equipment excavator 390D series HE4019, one of the main tools used to support the process of nickel production. Major constraint in using this tool is an insufficiently planned maintenance such that the tool affected operational and production process of nickel. Failure mode and effect analysis (FMEA) method is used to identify the risks of failure of critical components on the performance of the unit. Based on risk priority number (RPN), three critical components are found as leading causes of unit downtime. These are stick cylinder (RPN 288), fuel filter (RPN 280) and oil pan (RPN 240), respectively. Mean time between failure (MTBF) scores of stick cylinder, fuel filter and oil pan are 1,288.91 hours, 334.04 hours and 1,455.77 hours, respectively. Each of making rod of the cylinder covered, periodically flushing the fuel tank and taking on a warning sign on the couplers and coating the gasket with an additional layer during installation, in the meantime, are proposed as preventive maintenance for each the three critical components.

It takes a good maintenance management at any company to be able to run the production process effectively and efficiently. However, in practice often attempt maintenance or repair only be a waste, because the maintenance team does not know clearly the problems that occur and the factors. The purpose of this study was to measure the value of Overall Equipment Effectiveness (OEE), determine the magnitude of each factor of six big losses that affect the effectiveness of the defekator I machine, and an analysis of the factors that a top priority as the basis for repairs. In this study the method used Overall Equipment Effectiveness (OEE), and OEE six big losses to measure the performance of the machine for six months and to determine the factors of the six factors in the six big losses that give the most impact on the effectiveness of the defektor I machine. Based on the results of data processing, Overall Equipment Effectiveness value defekator I machine in purification station PT. Perkebunan XY, the ideal situation is achieved only in August and October with OEE value of 85.53% in August and 85.29% in October. Meanwhile, in June, July, September, and November OEE values are respectively 84.87%, 80.47%, 84.63%, and 76.89%. The results of the calculation of the six big losses, it is known that loss and rework loss breakdown is a factor with the largest percentage for the low effectiveness of the defekator I machine with a percentage of 63.57% for the breakdown loss and rework a loss of 24.23%. OEE and OEE value of six big losses are the basis for the provision of the proposed improvement.

This community service program (PkM) focuses on empowering the single parent woman community in Tetebatu Village, Kec. Pallangga Kab. Gowa through socialization, training, and mentoring activities to improve skills in making environmentally friendly soap products. This PkM activity is carried out in collaboration between the Department of Industrial Engineering, Hasanuddin University and the Tetebatu Village Office, Pallanga District, Gowa Regency. The focus of this PkM is single parent women with the hope that they will be able to be economically independent through the business they run in the future. A total of 10 single parent women participated in the two-day activity which included introduction of environmentally friendly products, environmentally friendly soap-making production practices and discussions related to soap entrepreneurship opportunities and marketing strategies. During the implementation of this activity, pre-test and post-test were also conducted for participants as a way to measure the success of the activity. The results showed that participants' understanding of the definition of environmentally friendly increased by 80%. In addition, 90% of participants also understand the benefits of environmentally friendly products and about 60% of participants have understood the procedures, methods, and hygiene standards in making liquid soap after socialization and training.

Delivery services are going through a transition phase globally due to changes in the market dynamics and growing e-commerce industries. As the delivery services of public logistics organizations have a lasting impact on customer behavior, logistics organizations are using innovative, customer-centric, and cost-effective strategies to offer customers convenient, attractive, and effective service solutions. The current study has been undertaken to analyze the effectiveness of each element of quality services of delivery services. Qualitative and quantitative research approaches were implemented based on a hundred respondents in identifying the critical issues based on the SERVQUAL method, heterogeneous customer satisfaction index (HCSI), and mapping out prioritizing the most critical problem. The study results reveal that customers are susceptible to the responsive, assurance, and empathy dimensions. These three of five dimensions are adversely influencing the satisfaction of customers.

This study aims to apply the Single Minute Exchange of Die (SMED) method in reducing setup time on a 350T capacity molding machine at PT HMG. The data collection results showed that the frequency of mold changes reached 70 times a month, with the average time required for mold changes before the implementation of SMED 173 minutes. After the implementation of SMED, the mold change time was successfully reduced to 64 minutes, reflecting a decrease of 63%. The implementation of SMED was carried out through several stages, including converting internal activities to external ones, which aimed to reduce machine downtime. Optimization of the remaining activities was also carried out, such as reducing the temperature drop time on the barrel and hot runner, which previously took 15 minutes, now only 5 minutes. The final results showed that machine downtime cost savings reached Rp11,200,000 per month after the implementation of SMED, with total downtime costs decreasing from Rp30,274,999 to Rp19,074,999 per month. This study proves that implementing the SMED method can significantly improve time efficiency, reduce production costs, and create more efficient operational standards. The findings provide a solid basis for further development in industry manufacturing practices.

Innovation is carried out systematically to develop and market breakthrough products, systems, or services that can solve customer problems. Companies that do not innovate or are not at a high-quality level become stagnant and can even go bankrupt. PT Arita Prima Indonesia Tbk was established on October 5, 2000, in Jakarta, Indonesia, and engaged in import, distribution, and service for valve, fitting, instrumentation, and control products. The expedition division is responsible for shipping goods to customers. In previous studies, implementing the nearest insert and nearest neighbor methods in shipping route planning can help minimize travel distances and increase the efficiency of the distribution process of imported products. The saving matrix method focuses on adding nearby consumers to complete existing routes. The system dynamics approach shows the unity of interaction between elements of an object within a specific scope that work together to achieve goals. This provides structure to the object, can differentiate it from other objects, and affects the state of the object. The highest total expenditure from month 1 to month 120 was on the carry box car amounting to 2681.32 million rupiah or Rp2,681,320,000. The lowest total expenditure from month 1 to month 120 was on the canter box car amounting to 2503.75 million rupiah or Rp2,503,750. The highest total cost from month 1 to month 120 was on the canter long car with the highest asset value (Rp290,000,000) amounting to 2843.77 million rupiah or Rp2,843,770,000 (two billion eight hundred forty-three million seven hundred seventy thousand rupiah). The lowest total cost from month 1 to month 120 was on the canter box car with the second highest asset value (Rp185,000,000) amounting to 2503.75 million rupiah or Rp2,503,750,000.
