Abstract

Production machinery and equipment are important elements in supporting the production sustainability of a manufacturing company. The machine becomes the main demand to continue to maintain and even improve the machine to remain optimal in producing goods and able to meet consumer demand. PT Cicor Panatec Batam is a company in Batam that manufactures beauty tools. some of the machines used, the Engel 200T, are injection molding machines, losses resulting from the production process caused by downtime that occur every day. The purpose of this study is to determine engine efficiency, six big losses which has the largest percentage of causes of engine performance decline, determine the low value of engine effectiveness from the factors and root causes of the problem, and make suggestions for improvement. In this study the determination of the value of the effectiveness of the machine using the OEE method and steps to correct the problem using FMEA. Obtained the OEE value calculation is 48.85%. In the Pareto diagram, the low value of the engine effectiveness is the breakdown losses with a value of 42.50%. Conduct identification using Ishikawa diagram to identify the cause of breakdown losses. The dominant problem causing failure is unstable heater heating with an RPN value of 140, and the smallest potential is damage to the mold RPN value of 90, proposed improvements to make SOPs, conduct periodic training, provide spare parts, and need to increase responsibility and care for care machine

Abstract

ABSTRACT The process is fast and does not cost much, is an action that needs to be done by the company to be able to achieve profits. Design is a strategy to support the achievement of the company in the production that is carried out, namely carrying out design activities which aim to provide a new design of the process by designing tools as a solution to the problem of its long production time. PT XYZ is a manufacturing company in the electronics industry which is engaged in the production of hard disk drive components, but the company did not arrive at the assembly, only making spare part components of these products. Problems occur when arranging the outer device crash stop charger product into the packaging media tray which is done one by one using tweezers, so that it has an impact on the long preparation time. Arranging the product into the media tray. Products that have round dimensions and diameters (2.63 x 1.08 x 4.03) mm, make it difficult for operators to arrange into holes in the tray and require a long time of 9.13 minutes. Design for.Manufacturing.and Assembly is the deepening of two methods namely Design for.Manufactur design that focuses on ease in manufacturing and DFA (Design for Assembly) design focuses on ease when the product assembly process. The successful implementation of JIG Arranging tools using the DFMA design method gave an increase in the Arranging process by 130%, where before 38 processes were 88 times a day. The Arranging process experienced an acceleration of time in a process where previously using Tweezers took 9.13 minutes, now using JIG Arranging only needed 3.95 minutes.

Abstract

PT MEB a company of electric energy in Batam. With production system integrated system by another, make the operational system machine primary production more complex and challenging. Because it, required control operational management system new and innovative point effectiveness to maintain optimal effectiveness level production so maintain capability of competitive and position company as quality electric producer. Research objectives know the level percentage value effective performance machine production and know causes factor effective performance machine does not maximum. Used the method OEE, cause of performance not maximum know through indicators 3 main categories. As for analysis calculation six big losses be to find out detail kind of waste. The benefits research adds to the literature for readers and writers the future understanding related the topic, give scientific work efforts to improve the effective performance the machine production in the company. Get the value percentage of research conclusion OEE production machine gas turbine generator at 83,49%, so the values still below OEE word class standart. Performance efficiency is major factor most influences the performance machine production not optimum at 88,67%. Analysis six big losses, get the speed losses as major factor the largest losses

Abstract

ABSTRACT Work fatigue is a problem that often occur at work area, this problem often ignored for continuity production of company. Uncontrolled work fatigue can caused a negative effect both physic and psychology for employee. In this study, the employee got workload about 35 kg/hour and overtime until 12 hour/day that caused the work fatigue. The aims of study to know a level category of work fatigue and factor of work fatigue what had the employee especially on warehouse of PT Indomarco Prismatama Batam. The method of the study used subjective self rating test that measure the level of subjective work fatigue toward the employee. The result of the study showed that the category of fatigue toward the employee of warehouse have a high level which is followed by a middle level. The result of Correlation Spearman test shows that working day (sig = 0,00), workload (sig = 0,00), the effect of work fatigue. The suggestion toward employee of warehouse conveys to do a job or workload based on physical ability and working capacity to take a short break. The leader of PT Indomarco Prismatama expects to increase mechanical equipment in loading and moving material activity even shifting working day correctly.

Abstract

Forecasting is a prediction of a future that got from detailed calculation results systematically based on current data and previous data in the certain period. To do forecasting, a lot of data that used to do a forecasting then our result could be accurate based on forecasting that we have already done. Forecasting of demand is needed by PT XYZ, Forecasting method that used are Exponential Smoothing method with α 0,1, 0,5 and 0,9 and Regression Linier method to predict the number of sales product of wooden box and wooden pallet that would occur in the months to come. The forecasting result with regression linear for six period later sequentially are 274,12; 274,99; 275,85; 276,71; 277,57; and 278,44 with the error level are MAD = 34,74; MSE = 1.637,51 and MAPE = 14,17%. From data processing analysis that already done that the best selected method is exponential smoothing with α 0,9 to forecast demand product of wooden pallet 110 cm x 110 cm. With forecasting result in six period later sequentially are 347,9; 369,7; 391,4; 413,2; 434,9; dan 456,7 with the error level are MAD = 4,14; MSE = 22,63 and MAPE = 1,65%.

Abstract

In general, all human activities are divided into two groups, namely work groups that use mental (brain), and physical (muscle) where both groups really need the work to be done. PT ABC. The First Heritage Dock is a branch of ABC where a company engaged in shipyard. In the department's warehouse there are 3 types of foklift used, namely forklifts with a capacity of 5 tons, 10 tons and 15 tons. Many jobs are given to employees who take mental and physical burdens presented by employees who have work stress. In carrying out the process of analyzing mental burdens for each employee, which is often used in conducting useful research using the NASA-TLX method (Expense Index Duties of National Aeronautics and Space Administration). This method is related to the emergence of the need for subjective reviews consisting of 6 main factors, In carrying out the process of physical work analysis on employees who are often used by research that uses the Cardiovascular Load method while the Cardiovascular Load itself is used to measure heart rate and pulse before doing work and after doing the work thus determines the level felt by an employee. In this study, researchers wanted to calculate the large level of mental work and physical forklift operators. The results of the calculation of mental workload and physical operator of the 5 Ton forklift are 70.38 and 36.36, for 10 Ton are 84.23 and 39.19, and for 15 Ton is 89.17 dam 44.18. It can be concluded that the mental workload of forklifts is very high.
