Abstract

The weaving operator of CV XYZ has an unergonomic work posture with a bent back and unbalanced legs at work. This non-ergonomic condition was identified by using the Nordic Body Map questionnaire to find out complaints on 28 body parts of three operators. From the identification of weaving operators using a nordic body map, it is known that there are complaints on the back, waist, and hips of the body. Identification using the Rapid Entire Body Assessment method shows that the final result of the assessment is 11, which means that there is a need for improvement now on the operator's work posture. The results of the QEC method show an exposure score of 97.12% for operator 3 and the action that must be taken is research and changes now. To reduce the risk of high work posture, a proposal for improving the working posture of the weaving machine set up operator was formulated by designing a manual scissor lift tool. In the process of designing tools, Indonesian anthropometric data is needed. The stages of designing tools are identifying operator needs, conceptualizing tools using a need metric matrix, selecting tools concepts with combination tables and scoring concepts and describing the design of tools using AutoCAD and CATIA software. From the results of the selection of several alternative concepts, a tool in the form of a manual scissor lift was chosen which has a combination of elements, namely a square working platform design, using 2 hydraulics and raw materials made of steel. Meanwhile, the manual scissor lift specification has a maximum height of 85 cm, a footing length of 70 cm and a footing width of 46 cm. It is known that before the proposed improvement, the final result of the REBA score was 11 and after the improvement the final result of the REBA score was 4 which indicates that the operator's work posture has improved after using the assistive device, especially in the arms, legs and back of the operator

降低障碍风险的辅助工具的建议设计（MSDS）织造工作站操作员CV XYZ

CV XYZ的编织操作员在工作时有一种不协调的工作姿势，背部弯曲，腿部不平衡。这种不符合人体工程学的情况是通过使用Nordic Body Map问卷来找出三名操作员对28个身体部位的投诉来确定的。通过使用北欧身体图识别编织操作员，可以知道身体的背部、腰部和臀部有缺陷。使用快速全身评估方法进行识别表明，评估的最终结果为11，这意味着现在需要改进操作员的工作姿势。QEC方法的结果显示，操作员3的暴露得分为97.12%，现在必须采取的行动是研究和改变。为了降低高工作姿势的风险，设计了一种手动剪式升降工具，提出了改进织机装配操作员工作姿势的建议。在设计工具的过程中，需要印尼的人体测量数据。设计工具的阶段是识别操作员需求，使用需求度量矩阵概念化工具，使用组合表和评分概念选择工具概念，以及使用AutoCAD和CATIA软件描述工具设计。根据几个备选概念的选择结果，选择了一种手动剪式升降机形式的工具，该工具具有多种元素的组合，即方形工作平台设计，使用2种液压装置和钢制原材料。同时，手动剪式升降机规格的最大高度为85厘米，基脚长度为70厘米，基脚宽度为46厘米。众所周知，在提出改进之前，REBA评分的最终结果为11，改进之后，REBA得分的最终结果是4，这表明操作员在使用辅助装置后的工作姿势有所改善，尤其是操作员的手臂、腿部和背部
