The development of the automotive industry in Indonesia made the level of competition even tighter, so Auto2000 Setiabudhi tried to provide periodic maintenance services, especially for the replacement of New Avanza Veloz disc brakes. The purpose of this study was to reduce the processing time of the New Avanza Veloz disc brake replacement to increase the Auto2000 Setiabudhi service level. However, the results of observations found that the time for disc brake replacement was exceeded the requirements set by the company. The observation was carried out for two years, from 2017 to 2018. Obtained also information from observations that there was an increase in the processing time gap of 0.84%, an increase in service level gap of 5.17%, while waste that occurred was waste waiting and motion. The method used in this study is based on Lean Six Sigma. The results obtained after improvements were made to a reduction in processing time by 50%, reduction in waste waiting, and motion and the achievement of service levels by 100%.

This paper purpose is to investigate the benefits of Lean Six Sigma to the Malaysian automotive industry. Lean is an approach that seeks to improve flow in the value stream and eliminate waste. It’s about doing things quickly. Six Sigma uses a powerful framework (DMAIC) and statistical tools to uncover root causes to understand and reduce variation. It’s about doing things right (defect free). As global competition continues to grow, the pressure to improve becomes more andmore intense. Thus, a combination of both Lean and Six Sigma is born. This method provides an over-arching improvement philosophy that incorporates powerful data-driven tools to solve problems and create rapid transformational improvement at lower cost. Thus, this paper also tries to examine how the Lean Six Sigma can contribute and brings a positive impact to the automotive industry in Malaysia.

PurposeThe article intended to excavate the Lean Six Sigma (LSS) deployment challenges, Critical Success Factors (CSF), tools and techniques, and managerial implications in an Indian healthcare setting.Design/methodology/approachThe article illustrates a case study established using Action Research (AR) approach. Further, the case study is based on the Define, Measure, Analyze, Improve, Control (DMAIC) phases of LSS. The performance and service quality of the Endodontics department of a dental college attached to a hospital is enhanced and sustained through the LSS strategy.FindingsThe processing time of Root Canal treatment is reduced by determining the root causes for delay and implementing sustainable solutions. The structured deployment of the LSS strategy helped the Endodontics department to reduce the processing time from an average of 116 min–84 min. Thus, the process's sigma level is enhanced from 0.06 to 4.17 and assisted in sustaining the results.Research limitations/implicationsThe case study's findings are based on the single AR carried out at an Endodontics department of a dental college hospital based on LSS strategies. Even though this study's results cannot be generalized, the deliverables of the case study can be used to develop the LSS roadmap for the dental colleges to enhance the service quality and safety of the patients.Originality/valueThe article provides step-by-step details for implementing LSS in dental college hospitals with critical analysis based on robust statistical tools and techniques. The case study provides evidence of the adoption of LSS in medical college education and provides the confidence to adopt the same through novice users. The study's findings may persuade the policymakers to add LSS in the medical education curriculum to reinforce safety and reduce errors in the healthcare system.

Penelitian ini dilakukan di sebuah perusahaan yang bergerak di bidang packing plant. Proses pada packing plant tersebut tentunya tidak terlepas dari permasalahan pemborosan yang menjadi kendala saat pengepakan semen berlangsung. Tujuan dari penelitian ini adalah untuk mengidentifikasi jenis-jenis pemborosan, mengidentifikasi akar penyebab pemborosan, mengeliminasi pemborosan dan memberikan usulan tindakan perbaikan dengan menerapkan Lean Six Sigma. Lean Six Sigma merupakan sebuah metode yang digunakan untuk mengeliminasi pemborosan yang terdapat pada lantai produksi serta mengidentifikasi penyebab kecacatan produk dengan pendekatan DMAIC (Define, Measure, Analysis, Control). Hasil penelitian menunjukkan jenis pemborosan yang paling berpengaruh adalah defect product, waktu pengepakan yang melebihi batas toleransi (OTIFIC), antrian, unnecessary motion, over processing, transportasi dan penumpukkan. Akar penyebab terjadinya pemborosan adalah karena kurangnya keterampilan, kurang teliti dan kelelahan, kondisi peralatan mulai aus serta kurangnya pemeliharaan pada peralatan yang digunakan, SOP kerja yang kurang tepat dan mendetail, alur transportasi yang bolak-balik karena tata letak yang tidak tepat. Aktivitas yang merupakan pemborosan dan harus dieliminasi adalah saat operator packer kedua menghitung ulang jumlah bag. Dari hasil penelitian didapatkan beberapa usulan perbaikan yakni dengan memperbaiki SOP kerja yang ada, menerapkan program 6S, membuat SOP 6S, melakukan pelatihan kerja, membuat standar kriteria khusus dalam proses perekrutan karyawan, membuat label atau tanda pada tiap tumpukkan bag, melakukan pemeliharaan secara rutin dan berkala, melakukan pengawasan terhadap kinerja karyawan serta membuat peraturan baru untuk mendisiplinkan karyawan. AbstractThis research was conducted in a company engaged in the packing plant. The process of packing plant is certainly not separated from the problem of waste that become an obstacle when packing cement in progress. The purpose of the study was to identify the types of waste, identify the root cause of waste, eliminate waste and provide proposed corrective action by implementing Lean Six Sigma. Lean Six Sigma is a method used to eliminate waste on the production floor and identify the cause of product defects with the approach of DMAIC (Define, Measure, Analysis, Control). The results showed the most influential types of waste are defect product, packing time exceeding the tolerance limit (OTIFIC), queuing, unnecessary motion over processing, transportation and stacking. The root cause of waste is due to lack of skills, less through and fatigue, equipment condition began to wear and lack of maintenance on the equipment used, work SOP that is less precise and detailed, the flow of transportation commute due to improper layout. Activity that is a waste and should be eliminated is when the second packer operator recalculates the number of bags. From the research results obtained several proposed improvements namely by improving the existing work SOP, implementing the program 6S, creating SOP 6S, conducting work training, creating special criteria standards in the recruitment process, creating labels or marks in each bag, conduct regular and periodic maintenance, supervise the performance of employees and make new regulations to discipline employees.Keywords: DMAIC; Lean Six Sigma; Product Quality; Waste
