Abstract
Base Single Part is the main component of the cable installation that functions as a connector between cables in the aircraft. As a critical part, the Base Single Part is the most important sub-component that must be completed to be installed in the aircraft part. Base Single Part is a part that is used in all types of aircraft which are specially produced at PT. Dirgantara Indonesia, in one aircraft this component can be installed in the amount of 8000-9000 Base Single Part. In relation to the request from the Final Assembly Line section regarding the request for the Base Single Part component, there are still some products that do not meet the specifications so that they have to be repaired, such as holes that do not match the size, this causes the delivery order process to the Final Assembly Line section to be hampered and disruptive smooth production. The purpose of this research is to control the quality of the Base Single Part product by using a p control chart, and a causal diagram.The results of the study conclude that the calculation of the percentage level of defect in the Base Single Part component using the p control chart, there are 3 percentage points that are outside the control limit, namely in August with a disability percentage of 15.11%, in September 10.32%, and October 15.60%. Factors causing defects in Base Single Part components consist of 3 factors, human factors, method factors and machine factors. The human factor is workers who are less productive. Furthermore, the method factor is regarding the fluctuating production schedule and the last cause is the machine factor that lacks maintenance.
基础单部件是电缆安装的主要部件,在飞机中充当电缆之间的连接器。基础单件作为关键部件,是飞机部件安装中必须完成的最重要的子部件。Base Single Part是在印度尼西亚PT. Dirgantara专门生产的所有类型的飞机上使用的部件,在一架飞机上该部件可以安装8000-9000个Base Single Part。关于总装线部门对基础单件组件的要求,仍然有一些产品不符合规格,因此必须进行维修,例如尺寸不匹配的孔,这导致向总装线部门交付订单的过程受到阻碍,并破坏了顺利生产。本研究的目的是利用p控制图和因果图来控制基础单件产品的质量。研究结果表明,使用p控制图计算基础单部件缺陷百分比水平时,有3个百分点超出控制范围,分别是8月份的缺陷百分比为15.11%,9月份的缺陷百分比为10.32%,10月份的缺陷百分比为15.60%。造成基础单件件缺陷的因素包括人为因素、方法因素和机械因素3个方面。人为因素是生产力较低的工人。其次,方法因素是关于生产计划的波动,最后一个原因是缺乏维护的机器因素。
