Abstract

PT. UMSurya Bina Bangsa is a company engaged in the production of Bottled Drinking Water (AMDK). The products produced by PT. UMSurya Bina Bangsa include Suli 5 in 120 ml and 240 ml sizes, as well as S-Five in 330 ml and 600 ml sizes. The issues faced by PT. UMSurya Bina Bangsa include Defects such as dented bottles and broken caps. The aim of this study is to improve the quality of bottled water products. The author of this study uses the integration of Six Sigma and Failure Mode and Effect Analysis (FMEA) methods to improve product quality. Based on the research results, the Root Cause Analysis (RCA) indicates that the majority of product Defects are caused by operator inaccuracy and the use of low-quality materials. Failure Mode and Effect Analysis (FMEA) results show that the highest RPN is caused by the bottle cap pressing process. From the Measure phase, sigma level calculations show a sigma value of 2.10 with a DPMO of 36,041. Improvement recommendations include creating racks for bottle caps to reduce Defects in broken caps, and adding dividers for bottles to prevent crushing while on the conveyor. From the estimated calculations, after implementing the improvement recommendations, the sigma level is expected to increase from 2.10 to 2.54.

Abstract

PT ABC is a company in the manufacturing industry that produces premium spoons. The raw material used is 304 stainless steel. The high volume of defective production impacts reducing the level of customer satisfaction so that it indirectly causes losses to the company. The maximum defect rate determined and allowed by the company is 4.25% of total production. This study aims to determine critical defects and provide alternative improvements to reduce the level of product defects and increase the sigma level in making premium spoons. In this study, the Six Sigma method is used to determine the sigma level to be used as a reference in making corrective actions; the existing condition shows that the sigma level is 4.29, indicating that corrective steps need to be taken. The results showed that by analyzing Pareto diagrams, three critical defects occurred in spoon products: warping 98 pieces, freckles 102 pieces, and Discoloration 99 pieces. The root Cause Analysis method is used to identify factors that cause defects in spoons. The FMEA method is used to provide alternative improvements by reducing the potential for failure by considering the RPN value, where the RPN value of warping defects is 60, the RPN value of freckles defects is 60, and the highest RPN value obtained by Discoloration defects is 64. At the improvement stage, alternative improvements are given; from the proposed improvements, a decrease in the number of defects is obtained, which for warping defects is 15.5%, freckles are 16%, and Discoloration is 12.8% with a total decrease in the number of defects is 44.3%. From the results of the improvements that have been implemented, the DPMO value is 7,800 with a sigma level of 4.74. PT ABC adalah sebuah perusahaan dibidang industri manufaktur yang memproduksi sendok premium.

Abstract

Drying is a process of transferring heat and water vapor simultaneously which requires heat energy to evaporate the water content. This heat energy can usually be obtained from sunlight. However, during the rainy season, this condition inhibits the drying process that utilizes sunlight, so the drying process takes a long time. Therefore we need a tool that can dry clothes without depending on the heat source from the sun's rays. The clothes dryer is a tool used to dry clothes with artificial heat energy, one of the artificial heat producers is a heating element or what is often called a heater. The artificial heating element used in this research is Electric Heater. This Electric Heater is equipped with a fan that can produce an indoor temperature of up to ± 52.3º C so that the heat generated by the Electric Heater can convert the water contained in the clothes into water vapor which will then be released into the environment with the help of a fan. Based on the results of calculations and testing, the ability of this tool is able to evaporate an average mass of water of 535.8 grams/hour and this machine reaches its optimum point for the number of drying clothes that can be dried as many as 6 clothes.

Abstract

Alignment is a technique used to maintain machine components that rotate or transfer power so they can operate as effectively as possible and prevent damage to other machine components from errors made during installation or maintenance. Alignment is a maintenance activity that is often carried out on machines in industry and machines within the Morowali Metal Industry Polytechnic, especially in the Mechanical Maintenance Engineering Study Program. Competency in the alignment of gears and bearings is very much needed for prospective mechanics in the industry. The purpose of making this tool is as a simulation tool for learning alignment to achieve straightness and centricity between two rotating shafts (drive and driven shaft) to prevent friction, vibration, and other problems that can reduce tool life and, of course, increase expenditure costs. for repair or replacement of heavy equipment. In the process of designing this alignment tool, a drive method is used in the form of a sprocket and chain, where the link between the drive motor and the shaft to be moved is the sprocket and chain method. This research serves to help produce a design by considering the user's perspective so that the design results can be useful effectively. From the test results, the gear alignment setting tool can function well with the help of an inverter so that motor rotation can be reduced and can be controlled according to the desired conditions. The previous alignment setting tool had an RPM: of 1450.8 and the alignment setting tool that was made had an RPM: of 1455.7 with a frequency of 50 Hz so it can be concluded that this tool can be used for practical work in machine repair and maintenance laboratories.
