Abstract

XYZ is a major player in natural gas distribution in Indonesia, with an extensive pipeline connecting production sources with a wide range of consumers, including households, industries, and power plants. The network ensures an efficient and safe gas supply throughout the region, with good distribution control for reliable service. However, corrosion problems in pipes can threaten the integrity of the system. To overcome this, PT. XYZ implements precautions such as protective coating and cathodic protection. Risk analysis and scheduled maintenance help reduce the impact of corrosion and minimize maintenance costs. The findings of this study reveal that optimal treatment can be established by analyzing potential risks through certain methods. The approach allows for the identification of possible hazards and helps in determining the most effective treatment measures.Thus, organizations can take appropriate precautions to reduce risks and ensure efficient maintenance. Total Productive Maintenance TPM, which recommends that maintenance be carried out every 3 days, has succeeded in reducing the maintenance cost of PT. XYZ Previously, the company incurred maintenance costs from Rp. 60,600,000 to Rp. 55,200,000 per month with an efficiency of 9.78% through the analysis of the maintenance budget. With the right precautions, PT. XYZ ensures efficient maintenance to maintain the smooth distribution of natural gas in a sustainable manner.

Abstract

XYZ a manufacturer of nuts and bolts, frequently faced bolt former breakdowns that resulted in huge losses and disrupted the company's operational efficiency and reputation. To solve this problem, PT XYZ needs to implement an effective maintenance strategy and closely monitor machine conditions to reduce the risk of breakdowns and ensure smooth production. This can be analyzed using the OEE method that exists in the company to detect early symptoms of damage, and continuous monitoring of machine conditions. Based on the calculation (OEE) before maintenance scheduling is made on the bolt former machine is currently 69.34%, which is below the standard (JIPM) of 85%. Therefore, the machine still needs to increase productivity through the OEE and Six Big Losses methods and then proceed with analyzing the problem using a fishbone diagram. The results of the analysis found that the biggest factor of time loss was reduced speed losses of 23.15%. The value of setup and adjustment losses was 7.82%, idling and minor stoppages losses were 7.44%, equipment failure losses were 3.12%, defect losses were 0.99%, and scrap losses were 0.11%. After the implementation of OEE, it has an impact on the level of productivity with the calculation results increasing to 77.78%. The availability value reached 89.90%, the performance value was 87.75%, and the quality value was 99.57%.

Abstract

PT XYZ is a steel smelting company located in Sidoarjo. The company is assisted in the production process by a total of 15 cranes to lift loads that cannot be lifted by bare human hands. Currently the crane machine has the highest downtime of 157 hours compared to other machines. The components that are often damaged are the hover control, braking system, and trolley cable. The purpose of this research is to find out what causes high downtime, know the maintenance schedule, and can improve the reliability of critical components. This research will discuss the maintenance scheduling of crane machine No. 5 using the Reliabilty Centered Maintenance method. The results showed that the cause of high downtime is 3 critical components, namely hover control, braking system, and trolley cable. The proposed maintenance schedule for the 3 critical components has a maintenance time interval of hover control every 250 hours, braking system every 397 hours, trolley cable every 1460 hours, and the machine reliability obtained is 60%. The costs incurred for preventive maintenance amounted to Rp. 382,104,000, this figure increased by Rp. 185,840,000 from the cost of corrective maintenance which initially amounted to Rp. 196,264,000.

Abstract

This study designs a cutting and shaping tool for broom handles to improve production efficiency and reduce operator workload at Victory 2 Singa. The main issues include slow manual production processes, high costs due to the use of nails, and non-ergonomic tool designs. The proposed solution involves designing a new tool using Quality Function Deployment (QFD). Through QFD, customer requirements such as comfort, safety, durability, affordability, and ease of use are analyzed and translated into technical attributes for the tool. The results of the research show that the designed tool can meet the primary priorities, namely providing precise cutting results, ergonomic handle shapes, and an efficient working process.
