Peningkatan Kualitas Produksi Pelat Dinding Dan Atap Insulated Panel System Penerapan Metode Six Sigma Dengan Konsep Dmaic

Abstract

This research aims to identify, measure, and analyze process production of EPS (Expanded Polystyrene) Sandwich Panel produced by PT. BI. It also gave recommendation to improve the process production for increasing product quality. This products produced by PT. BI is still have high defects so that it need improvement to decrease defect product. The approach used to solve this problem is Six Sigma method based on the stages of DMAIC (Define, Measure, Analyze, Improve and Control). Identification for defect product consists of defects occurred in the process bending plate, gluing, press roll pressing and cutting. The results of previous research obtained DPMO (Defect Per Million Opportunities) value is 6500 and sigma level is 3.98. It has not reached the expected target of 6 sigma. Analysis using fishbone diagram and FMEA (Failure Mode and Effect Analysis) show that there is need for corrective action to improve company's performance. Proposed quality improvement is conducted by installing plastic roll (laminating coating) and replacing broken roll press. The result of proposed improvement shows DPMO value is 3227 and the sigma level is 4.22.

Application of The DMAIC Method in Improving The Quality of Electric Power Steering Housing Products

“…The results of this study show that based on sigma level the improvement is still small (1.5%) compare to 13% in (Girmanová et al, 2017), 29.1% in (Yadav & Sukhwani, 2016), 6% in (Usman, 2019), 37.6% in (Imtihan & Revino, 2019), but almost similar to (Dewi & Ummah, 2019) which is only 2%. However, based on this comparison, how far the improvement depends on the effort of the organization and the capability of its resources.…”

“…The DMAIC method has been successfully applied in various cases, including in the telecommunication industry (Abhilash & Thakkar, 2019) for reducing rejection rate in manufacturing of the doors in telecommunication cabinet, the automotive manufacturing industry to redesign tools to improve the welding process (Imtihan & Revino, 2019), engine boss drive face repair (Fithri & Yeni, 2016), muffler quality improvement for Colt Diesel FE 120 PS (Dharmawan & Ekawati, 2016), improving valve hole location in alloy wheel (Rijanto, 2014), reducing defective product in weaving department in the textile industry (Fithri, 2019), roof tile production process improvement (Dewi & Ummah, 2019), improving quality of apparel product industry (Tjandra et al, 2018), and (Subhan, 2018). DMAIC has also been successfully applied in government service offices by combining the lean office concept (Sukma et al, 2018), the personal care and home care industry (Nelfiyanti et al, 2018), the improvement of the concrete iron production process (Windarti, 2014), the weapons industry (Pakki et al, 2014), improving drilling ultra-shallow horizontal well (Wahyudi & Yudoko, 2019), improving the production quality of sandwich wall plate and roof panel (Usman, 2019) and also in bottling production (Kartini, 2019).…”
