Abstract

XYZ Village is an industrial village that produces woven fabrics. Failure in the production process is something that must be traced to the cause so that it can be used as a basis for improving product quality. Total Quality Management (TQM) is an approach to running a business that tries to maximize the competitiveness of an organization through continuous improvement of products, services, people, processes, and the environment. This study was conducted to identify potential causes of failure and improve the quality of woven fabrics in the weaving process in XYZ Village with the TQM method approach. Based on the calculations that have been done, it was found that there are two valid variables and two other invalid variables because the value of r-count > r-table, namely the variable color is less bright and the color is mixed. Then the main factors that cause the quality of woven fabrics to decrease and result in production failures on woven fabrics are inappropriate battens and also color spots on woven fabrics.

Abstract

Sounds that are not desired by the listener, where the sound can distract, interfere with activities, or cause danger during daily activities, can be called noise. Noise at a certain level originating from the sound of work tools in the production process can cause comfort and health to be disturbed. The lousy impact that often occurs if a person is exposed to noise for too long is the effect on hearing, which can cause deafness, but this can be controlled by using hearing protection equipment that will determine the amount of compensation value to be received by the surrounding community. The existence of the Landfill, which is often located in the middle of community settlements, has a direct impact, one of which is noise during every working hour of the Landfill's operations. One example of a Landfill that is still active today is the Klotok Landfill which is located in Pojok District, Kediri City. In this research, noise mapping was carried out to determine the pattern of noise distribution that occurs in the work environment. Making a noise contour map due to these activities will use a software called Surfer, which is a simple program to generate noise curves (noise contours) spatially the location of potentially hazardous areas. The result shows that activities at the Klotok Landfill have noise values ??ranging from 40 to 92 dB. The highest noise is in the location around landfill area 3, which is actively operating. The high noise level also can be found in the weighbridge, which is a place for transporting vehicles to pass. Evaluations at points 17, 18, and 19 indicated the need for protective wear, such as earmuffs or setting a break every 1.4, 3.6, and 2.2 hours for area workers.

Abstract

Landfill management in Indonesia is mostly operated by open dumping as well as the Klotok’s Landfill at Klotok Village, Kediri City. This landfill has three lands, and the third landfill is currently actively operating. The pollution is like the occurrence of leaks in leachate storage tanks which is near the Klotok river. That situation can make the leachate enter the river and affect the physicochemical conditions of the water which have an impact on decreasing the diversity and abundance of plankton. The diversity of plankton species in aquatic ecosystems is often used as an indicator to determine the primary productivity of waters and the condition of the aquatic ecosystem, so this research was carried out to determine the diversity of plankton species in the Klotok river, so the quality of the water can be known. This research was conducted in the Klotok River, Kediri City, East Java. Samples were taken upstream of the Klotok River, near the leachate treatment Plant, and downstream of the Klotok River. Samples were taken as much as 21 liters by pouring method. The samples are poured into plankton nets. The result shows that plankton diversity in the water body near Klotok landfill is between 0,49 to 0,67, which indicates that the diversity index according to Shannon-Wiener is 0,49 where the species diversity is low, the number of individual species is low, the ecosystem is unstable, and the waters are degraded.

Abstract

A furniture company has production scheduling problems by streamlining production output with one machine. This research aims to increase the work effectiveness of furniture companies by using a single machine and comparing several of the most efficient methods. The methods used are the FCFS, SPT, LPT, and EDD methods. From the research results of these four methods, it was found that the best method to use was the SPT method. However, there are still obstacles in the form of using a single machine which still really slows down the manufacturing process of a product. Products will still experience delays if the number of orders coming in increases. Therefore, a furniture company needs to add machines to reduce or minimize production delays that occur in the company. It would be better for future research to use other methods so that we can compare the results of another method.

Abstract

XYZ is a company operating in the manufacturing and rubber roll service industry located in Indonesia. The frequent issue within the company is the occurrence of product rejects, leading to inefficient production processes. The research is conducted using the Fault Tree Analysis (FTA) method with recommendations for improvement from the Failure Mode and Effect Analysis. This method is employed to identify the causes of product rejection and provide preventive solutions to avoid such rejections. There are three types of rejects at PT. XYZ, namely blisters rejection with a probability of 1.137%, material impurities rejection with a probability of 1.18%, and PU rejection with a probability of 1.152%. The root causes of these rejections include operators rushing, operator fatigue, machines in need of maintenance, very short production deadlines, operator laziness, incomplete environmental cleanliness facilities, and operators joking around while working. As for recommendations to reduce and prevent the recurrence of these three types of rejections, they include regular machine maintenance, providing customers with longer estimated completion times than the actual estimates, and offering rewards to operators who meet targets without making errors.

Abstract

XYZ is a company that operates in the frozen food industry in particular. The company is a producer of high-quality frozen food products for export, so, naturally, other stakeholders in each division of the company need to work together well. Machine maintenance is a key aspect in maintaining the performance and reliability of industrial equipment. To increase machine maintenance efficiency in this factory, a comprehensive and structured approach is needed. Therefore, this research will discuss the machine maintenance strategy implemented in the Sabroe production line. The two methods that will be the main focus of this research are Reliability Centered Maintenance (RCM) and Maintenance Value Stream Mapping (MVSM). The conclusion obtained by examining the highest Risk Priority Number (RPN) for each component in the blanching machine, it can be concluded that the gearbox component has the highest RPN, namely 216, which is the result of multiplying the Severity, Occurrence, and Detection values. During the period of breakdowns and repairs of the blanching machine, the Mean Time to Failure (MTTF) is found to be 242.2538 hours. Meanwhile, the Mean Time to Repair (MTTR) reaches 172.6 minutes or equivalent to 2.8 hours. The gearbox component requires a repair time of 2.8 hours. The inspection interval for the gearbox component is calculated for 302.01 hours, or every 12 days in a month. Efficiency analysis of maintenance using the Maintenance Value Stream Mapping approach indicates that the percentage of maintenance efficiency reaches 73.2%. Activities that add value require a longer time, around 172.6 minutes, while activities that do not add value require about 63.2 minutes.

Abstract

When the MRT was first operated, operations ran smoothly and it is hoped that this condition will continue to be optimal in the long term and have efficient operational costs. As a corporation that offers transportation services, PT MRT XYZ distributes passengers. Fixed expenses, variable costs, and travel costs all have an impact on efficient operational costs. Minimizing operational costs to support other costs, like maintenance costs, is vital for MRT XYZ operations to run as efficiently as possible. The study's goal is to determine the MRT system's operating expenses. The optimal operational costs, which were determined by using the travel matrix computation, were IDR 1,267,110,000,000 based on the analysis and discussion's findings. The factors utilized according to Tyonardo, the MRT station area's function and the costs that affect operations are used to determine the variable number of passengers using financial modeling. Optimizing language costs is anticipated to be the primary determinant in deciding how much profit PT MRT will make.
