Abstract

PT XZY is a company that processes industrial salt in the Gresik area, East Java. During the production process, there are still some obstacles found in the machine, especially in the fluidized bed dryer machine. With several obstacles such as problematic fans, unstable fan rotation, temperature sensors not working, and others that can hamper the production process so that the machine experiences downtime which results in reduced machine effectiveness. The purpose of this study is to determine the value of machine effectiveness using the OEE method then find the most dominant type of losses for decreasing machine effectiveness and to analyze the root cause of failure in fluidized bed dryer machine components. The calculation results show that the OEE value of PT XZY is 58.25%, which is relatively normal but can still be improvised a lot. The most dominant type of losses for decreasing machine effectiveness is idling and minor stoppage losses with an average of 43.47%. Then for the root of the problem there is damage to the fluidized bed dryer engine components due to lack of discipline in maintenance, engine components are eroded to breaks, lubricants run out, excessive raw materials, incorrect operation, scuffed / chipped cables, and electricity failure.

Abstract

PT. Duta Beton Mandiri is a company that is part of DUTA BANGSA GROUP domiciled in the Pasuruan regency. PT. Duta Beton Mandiri is a manufacturing company that has been established since 2008 and engaged in the production of building materials or concrete industry which has products such as paving blocks, bricks, ready mix, and precast concrete. PT. Duta Beton Mandiri is still often faced with several defects in their production, especially in paving block products as one of their main products such as easily crushed paving, cracked paving, asymmetrical paving, non-dry/wet paving and also damaged paving which affects quality. The purpose of this study was to determine the presentation of the most dominant defects, the factors causing the defects, and the effects they caused, as well as to propose the appropriate improvements to improve the quality of paving block products. The methods used are Statistical Quality Control (SQC) and Failure Mode and Effect Analysis (FMEA). SQC tools are check sheets, stratification, histograms, paretto diagrams, scatter diagrams, control charts, and cause and effect diagrams. Meanwhile, FMEA is used as a proposal to improve the results of the cause-and-effect diagram. Based on the results of research on SQC, the most dominant defects were Easily crushed paving (38,34%), after that Cracked paving (28,86%), Damaged paving (13,83%), Asymmetrical paving (10,92) and Non-dry/wet paving (8,05%). Based on the results of analysis and calculations on FMEA, it is known that the problem causing disability with the highest RPN value of 384 is the machine factor with the cause of the paving block mold pallet in a dirty or worn position. Recommendations for improvements that can be made are by always checking the condition of the mold pallet before the production process starts on a regular basis.

Abstract

One of the deadliest strokes is a brain stroke. According to the results of many cases of brain stroke patients, there is a possibility that bad lifestyles such as smoking and drinking alcohol can cause high blood pressure. The goal is to classify triggers for brain structure symptoms by comparing several algorithms. From the results of this comparison, it is possible to obtain triggers with the highest number of triggers so that later brain structures can be diagnosed more quickly. In several algorithms namely nn , feature selection and GA. To group triggers for several brain stroke symptoms, to maximize feature weight and feature selection, data processing using rapidminer was continued with four algorithms: X-Fold validation and split validation with ratios of 0.5, 0.6, 0.7, 0.8 and 0.9. After this test, the most popular AUC values and methods, together with the Neural Net algorithm, the Optimize Selection (Evolutionary) feature, and using a Split Validation ratio of 0.9, produce numbers with very high accuracy. AUC of 0.549 and an accuracy value of 95.88%..

Abstract

PT. XYZ is a foundry company that has difficulty achieving production targets compared to previous years. This study aims to evaluate the level of productivity using the Objective Matrix (OMAX) method. The highest productivity value in September 2022 with a value of 540. Meanwhile, the lowest productivity value was in October 2022 with a value of 340. The amount of total production compared to the total use of raw materials plays an important role in increasing productivity. In the productivity criteria of effective working hours, the criteria of machine working hours, and production effectiveness show good values. While the criteria for the effectiveness of product defects are not good because they show the lowest value. Based on the analysis of the fault tree analysis (FTA) method, it was found that there were 10 basic events that caused problems from low productivity, namely the presence of inexperienced operators, no assembly marks on the mold, no mold density standards, no schedule for calibration, leaky storage roofs, lack of quality control in the supply of raw materials, no separation between raw materials, Sifting is not clean, lack of regular machine maintenance, and induction furnaces that are not cleaned every production session.
