The objective of this research is to improve the overall result and pass percentage of students in degree level technical institutions by eliminating the failure causes using lean six sigma method. A case study was carried out in a degree level technical institute, which has a total intake of 720 students producing 54% of results for the past five years. Taking as a challenge issues to produce more than 75% of results, it was considered to carry out a study using lean six sigma approach. In this research five stage methodology of six sigma i.e. DMAIC have been used to reduce the parameters that affect the system. Failure mode effect analysis, histogram, process capability analysis and fish bone diagram methodologies were also adopted to analyze the depth of the issue and to identify the critical factors that requires to be controlled and to improve by implementing the solutions and remarks received from the stakeholders. From the results it was found that, through this approach the pass percentage level of the technical institute had increased from 54% to 75% by identifying and reducing the appropriate source of failures.

Cause And Effect Diagram

A component in machining is accepted when the dimensions are within the tolerance specifications. In aircraft components machining, controlling the weight of the components is of high importance. In this paper, a new concept called near minimum material zone was introduced, which would address the control of the weight of the aircraft components in machining. To prove this concept, two sets of experiments with 20 samples were conducted using Deckel Maho CTX310 ECO VI CNC machine. The first experiment was conducted with normal machining processes. The second experiment was conducted using a new concept. Lean Six Sigma DMAIC methodology was adopted for this study. Several Six Sigma tools such as process capability analysis (Cp, Cpk), cause and effect diagram, X Hi/Lo and R-charts, etc. were used. The paper suggests that this new concept not only helped to control the weight of the aircraft components but also improved the desired quality by minimizing the dispersion of the component dimensions to obtain higher sigma level.

Hasil observasi di PT. Holcim Indonesia Tbk, pabrik Cilacap, didapati banyaknya pemborosan di bagian pengepakan semen, termasuk banyaknya produk cacat kemasan, sehingga banyak semen tercecer dan harus mengulangi proses pengepakan. Penelitian ini dilakukan untuk mengidentifikasi pemborosan selama proses pengepakan menggunakan  pendekatan lean manufacturing dengan value stream mapping. Sementara tingkat kualitas dianalisis dengan metode six-sigma. Penyebab kecacatan produk dianalisis dengan fish-bone diagram. Failure Mode and Effect Analysis (FMEA) digunakan untuk merancang ususlan perbaikan. Pemborosan yang teridentifikasi meliputi : transportation, motion, waiting, over processing, dan defect. Usulan perbaikan untuk mengurangi pemborosan yaitu dengan penggabungan stasiun penimbangan dan stasiun pemeriksaan, sehingga memberikan estimasi peningkatan  process cycle effisiensi  dari 39,1% menjadi 46,69. Sedangkan upaya untuk mengurangi cacat produk dilakukan dengan perawatan preventif mesin packer.

This paper presents the improvement of the procurement process for raw materials in a real manufacturing company supported by the Lean Sig Sigma as structured approach to deliver the improvement. The manufacturing company that is a subject of this paper have received a significant amount of complains regarding the internal purchase orders approval process and the overall procurement process of the company from both internal employees and external vendors and contractors. Considering that the company is procuring the raw goods from selected vendors, therefore the entire manufacturing plan depends on these materials, the company decided to improve this process trough Lean Six Sigma. The Lean Six Sigma approach was selected in order to obtain the improvement in a short time, based on indicators that were previously analyzed and prioritized. The paper focuses on simplifying of the process trough decreasing the number of mandatory steps.

Lean Six Sigma has found wide spread applications in Industry with many benefits. However, its use in academics is limited. In this paper, we propose how Lean Six Sigma can be applied in University environment and many benefits can be observed in cost savings, quality and performance. The application of DMAIC approach of Lean Six Sigma to academics is illustrated with examples and case studies. The processes and practices in Universities and Educational Institutions are identified which can directly benefit from Lean Six Sigma.

Commercial banks and Bank Perkreditan Rakyat are two different types of banks whose existence in society aims to raise and channel public funds to improve people's lives. The facts show that there is a sharp competition between the two types of banks in terms of gaining public trust to become bank customer but although these two types of banks are different but still able to develop well in society. This study aims to identify the factors that become competitive advantage at Commercial Banks and Bank Perkreditan Rakyat from the customer's point of view based on customers' perceptions, expectations and interests so banks can determine competitive strategy. The approach used in this research is Lean Six Sigma approach with a sample of 60 respondents consisting of 30 customers of Commercial Banks and 30 customers of Bank Perkreditan Rakyat. Respondents will be asked to respond to research instruments based on their perceptions, expectations and interests. The results of the study there are five competitive advantages in Commercial Banks (1) promotions made, (2) reward appeal, (3) saving security, (4) cleanliness and comfort of the room, (5) friendliness, courtesy and neatness. Bank Perkreditan Rakyat obtained competitive advantage that is (1) cleanliness and comfort of the room,(2) ability and alertness of the officers, (3) friendliness, courtesy and neatness, (4) saving security, (5) familiarity  of the officer with the customer. In addition there are similarities there are interesting differences that is on the excellence of promotional activities and the attractiveness of prizes at Commercial Banks. and the familiarity of officers with customers at Bank Perkreditan Rakyat.
