Abstract :

Crafting industry is one of the creative economy subsectors under the Ministry of Tourism and Creative Economy of the Republic of Indonesia. PT Global Kriya Nusantara or later will be mentioned as Kriya Nusantara is one of the craft industry actors in West Java, specifically in Bandung City. Established in 1995, Kriya Nusantara exported craft goods to several countries. In order to fulfil its demand, Kriya Nusantara needs a great strategy, especially for its quality management. In this case, the proposed system to be improved is the quality management of Kriya Nusantara due to the occurrence of rejected products in one of its project production processes. One of the projects that will be analysed in this research is Ramadhan Box 2022 which was ordered by Al-Jazeera Perfumes – Qatar. The problem is, that there are some defective finished goods that later will be rejected and needs to be repaired or reworked.

The Six Sigma method has been utilised in this research as a primary tool. The Six Sigma in this research contains the DMAIC framework that will be useful to define the main issue, measure the capability of the process, analyse the business situation, and propose the improvement plans along with the control plans for the production process of Kriya Nusantara. According to this research, there are six defect types that occurred in this production process, and the defect type that has the greatest RPN value is the Minor Paint Defect with a 320 RPN value and has critical risk level. The causes of each defect type have been analysed using FMEA analysis and there are four causes which are human error, miscommunications, unskilled labour, and defective raw materials. The FMEA analysis also has been utilised to propose the business solution alternatives in this research. There are three proposed business solutions for the causes which are progress monitoring for the human error and miscommunication issues, labour training for the unskilled labour, and supplier’s product evaluation for the defective raw materials. Those improvements will reduce the defect of the products so that the quality of the products of Kriya Nusantara will be enhanced.
