Abstract

One of the problems with the Vehicle Routing Problem (VRP) is the problem of fulfilling customer requests according to the location that must be supplied from depots that have limited vehicle capacity. This also happened to Distributor PT. XYZ is located in Lamongan. Every day the distributor of PT. XYZ distributes fertilizer to several cities in East Java, one of which is in the city of Blitar. The problem that happened to the distributor of PT. XYZ does not yet have an optimal distribution route, resulting in delays in the delivery process. Optimization of distribution routes can be done by finding the shortest route in fertilizer distribution in the Blitar area. With the saving matrix and nearest neighbor method, the best route arrangement can shorten the distance and product delivery time. The final result will be savings in distribution costs because it can reduce fuel consumption for fertilizer trucks, reducing the company's variable costs and reducing environmental emissions.

Abstract

Many companies still do not prioritize occupational health and safety, causing a large workload to be borne both physically and mentally. It affects the workers ' fatigue and will affect performance. Work fatigue is a symptom associated with decreased work efficiency, skills, boredom, and increased anxiety. PT. XYZ is a manufacturing company, which produce refractory stone from clay as the main raw material. The production process uses human-machine power, lack of rest time, overtime to achieve production targets, repetitive and standing work, and a long-distance between milling stations and raw material processing. A few people only carry out the final part of the process. With this problem, this study uses Cardiovascular Load and Bourdon Wiersma to slow down worker fatigue and is expected to help measure worker fatigue to provide a solution in slowing down worker fatigue. The number of samples used as many as 20 workers. The results obtained from the analysis of this work system are shift one and shift two have different levels of fatigue, namely shift one high category and shift two low categories, as well as the mental load shift one is low while shift two is high, therefore shift one needs to be the improvement in his physical load while shift two needs to improve his mental load. Corrective actions that can be taken in shift one are to increase the rest time from 45 minutes to 60 minutes, implement a worker rolling system, and improve workplace conditions to make it more ergonomic. Corrective actions that can be taken in shift two are providing music, arranging work shifts such as rolling shifts, and adding rest periods.

Abstract

A manufacturing company in production activities requires machinery and equipment. The machine has reliability, namely the opportunity for the machine to operate according to its function in a certain period. Company XYZ is a company located in Sidoarjo and is engaged in manufacturing with the main product being White Crystal Sugar (GKP). Company XYZ has several machines or equipment that operate 24 hours throughout the milling season with a series and parallel system so that the probability of damage to machine components is quite high. One of the machines that are often damaged is the boiler engine. Based on the problems that exist in this company, it is necessary to evaluate the engine performance at the boiler station during the milling period. The methods used in this research are Overall Equipment Effectiveness (OEE) and Root Cause Analysis. The OEE value obtained by the machine at the boiler station at Company XYZ for machines that have a value above the ideal standard of 85%, namely bagasse carrier IV, bagasse carrier III, bagasse carrier II, belt conveyor, reclaimer I, and reclaimer II. Meanwhile for machines that have a value below the ideal standard of 85%, namely boilers KCC of 77.98%, boilers FCB of 81.73%, and bagasse carrier I of 82.37%. This condition shows that production is considered reasonable, but still shows that there is a large room for the company to make developments.

Abstract

PT XYZ is the largest shipbuilding company in Indonesia. The company's products are shipbuilding and ship design based on consumer demand. In the production process of the BRS W-303 ship, defects were still found during welding, such as incomplete penetration and slag inclusion. The purpose of this study was to determine the percentage of the most dominant defects and the factors causing defects and to provide suggestions for improving the quality of welding. The methods used are Statistical Quality Control (SQC) and Failure Mode Effect Analysis (FMEA). SQC tools are check sheets, stratification, scatter diagrams, attribute control charts, and cause and effect diagrams. Then continue the FMEA analysis based on the cause-and-effect diagram for proposed improvements. Based on the results of Statistical Quality Control (SQC) research, it is known that the most dominant ship welding defects are incomplete penetration (32.81%) and slag inclusion (23.26%). Based on the results of research on Failure Mode Effect Analysis (FMEA) it is known that the root cause of the highest problem with RPN 288 is the determination of the root gap is too small or narrow. Recommendations for improvement that can be proposed are to ensure that the welder must read and understand the WPS used to weld correctly.
