CV. Surya Teknik Mandiri is a company engaged in lathe and welding services located in Serang-Banten. Work is usually done such as screw making and welding of axle cages, where products are made according to customer orders. This study focused on one part of the work that has the highest level of fatigue through a fatigue questionnaire caused by squat work postures, namely the welding section involving two operators. This study aims to determine the measurement value of the exposure score, exposure level and to reduce MSDs complaints with the design of repair tools for welding operators in this study using the Quick Exposure Check (QEC) research method by distributing observer questionnaires and operators, and using the Anthropometry approach in measuring design tools for improving operator work posture. Based on the results of research on welding operators 1, the total exposure score was 106 with an exposure level of 59.55%. While for operator 2, there is a total exposure score of 124 and an exposure level of 69.66%. An action level for both operators needs further research and changes. Next, repairs are made to reduce the exposure level value in the welding work. Repairs are made with the aim of making the condition safe, comfortable and do not cause complaints MSDs when working, namely at the workstation standing by designing a tool in the form of a welding work desk. After implementing the welding workbench for the two operators and recalculating the QEC value, the operator one exposure level of 48.31% and for operator 2 49.43% with action levels need further research.
简历。Surya Teknik Mandiri是一家位于Serang-Banten的从事车床和焊接服务的公司。工作通常是做螺杆制造和桥笼焊接，产品是根据客户的订单。本研究通过一份深蹲工作姿势引起的疲劳调查问卷，针对工作中疲劳程度最高的一个部分，即涉及两名操作人员的焊接部分。本研究采用快速暴露检查(QEC)研究方法，通过发放观察员问卷和操作人员，利用人体测量学方法测量设计工具以改善操作人员的工作姿势，以确定本研究中焊接操作人员的暴露评分测量值、暴露水平和减少MSDs投诉。根据对焊接操作人员1的研究结果，总暴露得分为106分，暴露水平为59.55%。操作者2的暴露总得分为124分，暴露水平为69.66%。双方的行动水平需要进一步研究和改变。接下来，进行修复以减少焊接工作中的暴露水平值。维修的目的是使条件安全，舒适，并且在工作时不会引起投诉msd，即在工作站站立时设计一个焊接工作台形式的工具。在对2名操作人员实施焊接工作台并重新计算QEC值后，操作人员1暴露水平为48.31%，操作人员2暴露水平为49.43%，动作水平有待进一步研究。

A yarn company strives to produce good and quality products, but the production process that is carried out by each person will produce products targeted at a target that has been set at 5%. This study uses the Six Sigma method but only until the improvement stage. The research is to determine the DPMO value and sigma level in the spinning production process, to know what factors cause defects and new parameters to reduce the defect. Based on the results of the study that the DPMO on the type of CD thread in the spinning section is 17,130 and the sigma level is 3,6. The level of sigma that has dominated the Indonesian industry average, but has a defect of 8.7%, the target set at 5%. Damaged and dirty apron, clogged trumpet, and leaky hose are factors that plan defects. Furthermore, with Failure Mode Effect Analysis (FMEA), the highest value of Risk Priority Number (RPN) in tangled defects is that the apron is damaged (140) and clogged trumpet (120), while the highest RPN value is gross dirty, i.e., dirty apron (150) and hose leaking lubricant (120).

This research was conducted in an international company engaged in iron and steel products manufacturing industries. One of the equipment that is often damaged is a hot roller table machine in the furnace section mill unit. The availability results obtained in hot roller table equipment is 96.571% and is still below the company standard which is set at 98%. Therefore, we need an analysis of the root causes of the problem and search for the best solution to fix the existing problem by applying the method of Failure Mode and Effect Analysis (FMEA). FMEA is a method that can systematically and structurally analyze and identify the consequences of a system or process failure, and also reduce or analyze the probability of failure. The purpose of this study is to identify and analyze the level of damage and its causes with the application of the FMEA method. Based on the pareto diagram the damage to the hot roller table machine, it was found that the highest frequency of damage was in the rotary coupling with a down time percentage of 26.9%. From the FMEA Analysis, two components that have very high RPN values are categorized as potential severit i.e. bearing as the first with an RPN value of 392 and the second is a seal ring with an RPN value of 294. The two components are the main priority for repair of the furnace section. mill, especially for machine and human aspects.
本研究是在一家从事钢铁产品制造业的国际公司进行的。其中一个经常损坏的设备是炉段轧机单元中的热辊台机。热辊台设备的合格率为96.571%，仍低于公司设定的98%的标准。因此，我们需要运用失效模式与影响分析(Failure Mode and Effect analysis, FMEA)的方法，分析问题的根本原因，寻找解决问题的最佳方案。FMEA是一种能够系统地、结构化地分析和识别系统或过程失效的后果，并降低或分析失效概率的方法。本研究的目的是应用FMEA方法识别和分析损伤程度及其原因。通过对热辊台机损伤的帕累托图分析，发现旋转联轴器损伤频率最高，故障时间占26.9%。从FMEA分析中，两个具有非常高RPN值的部件被归类为潜在严重部件，即轴承是第一个，RPN值为392，第二个是密封圈，RPN值为294。这两个部件是修复炉段的主要优先部件。磨机，尤其适用于机器和人的方面。
