"Penelitian bertujuan untuk mengidentifikasi alur proses pelayanan dengan menggunakan pendekatan lean six sigma dan memberikan usulan perbaikan di Instalasi Radiologi RS Hermina Tangerang. Penelitian ini merupakan penelitian operasional (operational research) dengan desain penelitian kuantitatif dan kualitatif yang didapatkan dari hasil observasi, wawancara mendalam, dan telaah dokumen. Sasaran penelitian adalah pemeriksaan radiologi konvensional sebanyak 31 sampel. Hasil yang didapatkan dari pengukuran value stream mapping (VSM) adalah rata-rata lead time per pasien 2 jam 26 menit 42 detik pada shift pagi siang dan 12 jam 34 menit 53 detik pada shift malam. Bottleneck terletak pada siklus pengolahan ekspertise dikontribusi oleh sebagian besar waste of waiting, yaitu menunggu foto dibaca oleh dokter spesialis radiologi. Akar penyebab masalah adalah tidak ada jam praktek dokter spesialis radiologi pada shift malam hari serta belum diterapkan standarisasi waktu tunggu pelayanan radiologi untuk semua jenis pasien. Usulan perbaikan yang diberikan adalah dilakukannya standardized work, visual management, dan just in time sehingga diestimasikan lead time dapat dikurangi sebesar 26,47% (1 jam 47 menit 52 detik) pada shift pagi dan siang, serta shift malam 49,35% (6 jam 22 menit 28 detik).

The purpose of this study is to identify the service process flow using lean six sigma approach and giving improvement suggestions in radiology instalation at Hermina Tangerang Hospital. This is a quantitative and qualitaive operational research which the data was collected from observation result, in-depth interview, and document review. Target research of the study was the coventional radiology examinations with 31 samples. The result based on value stream mapping (VSM) measurement showed the average lead time per patient is 2 hours 26 minutes 42 seconds in the day shift and 12 hours 34 minutes 53 seconds in the night shift. The bottleneck is located in the expertise processing cyle which dominantly contributed by waste of waiting by waiting the image to be interpreted by the radiology specialist doctor. The root cause of the problem was the unavailability of the radiology specialist doctor in the night shift and there is no standardization of patients waiting time in the radiology services.  The improvement suggestions are the radiology department needs to apply a standardized work, visual management, and just in time, so that it is estimated that the lead time can be reduced 26,47% (1 hour 47 minutes 52 seconds) in the day shift and 49,35% in the night shift (6 hours 22 minutes 28 seconds)."

"Peningkatan Indeks Kualitas Produk Pada Tahap Pengembangan Produk di PT. XYZ Dengan Metode Six Sigma. Tesis ini membahas penggunaan metode six sigma (DMAIC) untuk memperbaiki indeks kualitas pertama pada tahap pengembangan produk Final Engineering Piloting (FEP). Pada fase define diketahui bahwa rata-rata indeks kualitas pertama pada tahap FEP sebesar -336, 27. Pada fase measure ditemukan bahwa rendahnya indeks kualitas diakibatkan oleh permasalahan pada torso dimana gaya untuk melepas dan memasang tangan dari dan ke lower arm berada di luar spesifikasi.Analisis menggunakan FMEA merekomendasikan agar material lower arm diganti dari PVC 85 menjadi PVC 65. Pergantian ini bisa membawa perubahan lebih baik, dan setelah perbaikan pada fase improvement didapatkan peningkatan indeks kualitas menjadi 5,46.

This paper discuss about the use of six sigma method (DMAIC) to improve first quality index during development product phase called Final Engineering Piloting. During define phase, found that average first QI FEP is -336,27. Measure phase shows that those index mostly contributed by torso problem, in which poundage to attach and detach hands to and from lower arm are out of product specification.

Analysis phase using FMEA, recommends to change material for lower arm from PVC 85 to PVC 65. This changes can improve product and after all the improvement implemented, average first quality index improve to 5,46."

"Is Six Sigma the exclusive domain of manufacturing and service operations, or can excellence be mandated (and achieved) throughout an entire organization? This refreshing book reveals how to apply the legendary quality assurance program across all departments and processes, creating a permanent, company-wide Six Sigma culture. Author Alan Larson, a Motorola veteran, has created a simple and practical Continuous Improvement model, and offers a strategy for managing the change to Six Sigma-driven operations and philosophy."

"Nowadays, Industries in this world wide are very competitive. The increasing quality ofa product is the main thing to satisfy the customer. One way to improve the quality of a product is by decreasing costs that came from the defect of a product. One methods which is used and succsed in big company in order to decreasing defects ofa product is Six Sigma. SixSigma found by Motorola Cpmpany in about l98O. Six Sigma method describe step by step with Define Measure Improve Control (DMAIC) way to make company more focus to what their aim to.In this observation, SixSigma is used in assembly process because many defecs are founded in this Process. The product that being observed are running Nike shoes which will be export to whole continent in this world. The aim of Six Sigma implemention in this Subcontractors Nike are decreasing the amount of defects with knowing the value of sigma and yields as a result of processing the quantitative data. Systematically and conlinously the calculation result the categorize of the company level as an average industiy. From the result of the calculation, analyzing by Six Sigma method will somuch helping to determine Risk Priority Number (RPN) from Failure Modes Electrict Analysis (FMEA) which resulted no quality and inspection standard PT. Pralama Abadi Industri."
