Abstract

PT. Intidaya Dinamika Sejati is a workshop company as well as the official holder for importers of blowers and vacuums in Indonesia with Pedro Gil and Becker as its brands. As a company that has a vision and mission to become a public company, it is appropriate to need a stable system that has a concept of continuous improvement to support success. This research began with the purchase of goods which are always processed even though the availability of goods was adequate, the cause of this incident was the difference in the physical stock in the warehouse with the stock recorded in the system. The purpose of this research was none other than to find out the root cause of the problem from the incompatibility of recording and storage data. The research was conducted by observation method. The results of the study stated that the discrepancy was caused by logistics management and warehouse management that lacked discipline both from the operational and warehouse management side, which resulted in discrepancies in the recording results. Through the results of the analysis, it is found a suggestion in the form of using the bar code method which includes rearranging the storage system, updated operating standards, and an organized recording method. From the result, it is expected to provide a concept that can be implemented and as a support in the company development process.

Abstract

CV Jamatex is a company engaged in the textile industry. One of the products produced by CV Jamatex is a patterned rayon fabric. The high level of defects and the absence of monitoring of the production process are the two biggest obstacles experienced by CV Jamatex. In the analysis of the problem for a high level of defects in this report, there are four types of defects, namely the types of defects in the rayon fabric which are stained, faded, torn and dirty. To analyze the level of disability is done using the five whys analysis method. For these four types of defects, improvement plans have been made, in the form of form printing worksheets, machine maintenance worksheets, work instructions, and prototype stenter machine aids. Whereas for problem analysis there is no monitoring of the production process, this is because monitoring at CV Jamatex is still quite simple. The design of the improvements made is to monitor the production process through the Microsoft Excel platform. The design of improvements in this final project report aims to overcome two problems that occur at CV Jamatex. The company has validated the proposed improvements.

Abstract

PT X is a company that is engaged in the gold jewelry industry. The problem found in the company is that the jig management system currently used by the company for the maintenance and repair process is not working well because the current system can be said to be ineffective. The problem causes many damaged jigs that require repair but are not immediately repaired because the current system is complicated for companies to detect damaged jigs. If the damaged jig is still used, it will cause the goods to be worked on to become defective and have to undergo a re-process. The number of technicians on duty is also limited so it requires a structured system so that technicians can make the best use of time in performing maintenance or repairing Jigs. So improvements are proposed in the form of methods to overcome the shortcomings or gaps of the current system. The methods will be related to automation to reduce errors from intentional or unintentional workers. Furthermore, a Standard Operating Procedure (SOP) is also made regarding the methods used by technicians in the Jig maintenance or repair process.

Abstract

PT. Sentosa Laju Sejahtera is a contracting company engaged in coal and mineral mining industry. PT. Sentosa Laju Sejahtera is facing low reliability problem due to a high rate of functional failures. To address this issue, a study was conducted using Reliability Centered Maintenance (RCM. The goal of RCM is to determine the best type of maintenance. RCM is assisted by two other methods, namely Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA). FMEA aims to identify the models that has highest number of failures and rank them based on the highest risk value. Model AXOR 2528CH had the highest number of failures, with 2416 failures or 47% of all models. The two main causes were tyre component and brake system component. FTA aims to identify the root causes of problems related to the method, man, material, machine, measurement, and environment factors. The proposed solutions include implementing tyre inspection, ensuring consistency in brand selection, and creating tyre report. These proposed solutions have resulted in a decrease of 23.5% in the number of functional failures of the tyre components compared to April 2022 and an increase of 50.68% in the average duration of tyre component failures.

Abstract

In this increasingly advanced era, almost all products are sold using plastic-based packaging. One of these plastic packaging products is produced at PT. XYZ. In supporting the production process, PT. XYZ needs raw material in the form of the paper core which is produced by PT. XYZ in the Papercore Department. This study aims to find out what potential hazards exist in the new department, then how much risk assessment is obtained, and what controls can be carried out. The method used in this study is HIRARC assisted by observation and interviews with production workers and other company parties. In practice, this research will focus on identifying existing potential hazards, assessing hazard risks, and proposing risk controls. There were 15 potential hazards with a high and medium risk rating, consisting of 9 mechanical categories, 5 chemical categories, and 1 ergonomic category. The proposed risk controls include technical engineering, administrative controls, and the use of PPE. From the existing risk controls, a reduction in the potential hazard risk rating was obtained to 15 hazards with a low-risk rating.
