Introduction

The Department of Industrial Engineering has been facing challenges in meeting the standards set by the National Accreditation Board of Higher Education (BAN-PT) for the undergraduate and Masters programs. The graduation rates for the 2016 school year undergraduate program and the 2017 and 2018 school year Masters program have not met the expected standards. To address this issue, the application of the Lean Six Sigma concept is proposed to improve the quality of graduates through a systematic analysis of various stages.

Understanding Lean Six Sigma

Lean Six Sigma is a method that focuses on improving quality and reducing variability in the process. This concept is divided into five stages: Define, Measure, Analyze, Improve, and Control (DMAIC). The Define stage involves identifying the main problems being faced, while the Measure stage involves taking sigma level measurements to determine how well the process is running. The Analyze stage involves identifying non-value added activities contained in the process, and the Improve stage involves proposing a solution to overcome the identified problems. Finally, the Control stage involves evaluating the effectiveness of the proposed solution.

Application of Lean Six Sigma in the Department of Industrial Engineering

In the context of the Department of Industrial Engineering, the problem being faced is the study period of the 2016 undergraduate program students and the waiting time to get the first job for students in 2015 and 2016, which have not met BAN-PT standards. As for the Masters program, the problem faced is the study period for students in 2017 and 2018, which also do not meet accreditation criteria.

At the Measure stage, sigma level measurements were taken to determine how well the process is running. The measurement results show that the waiting time for the 2016 undergraduate program has the highest level of sigma, which is 3.09. As for the Masters Program in 2017, the study period gets a Sigma level of 2.06. This figure indicates a significant problem that must be overcome.

Analysis of Non-Value Added Activities

Continue to the Analyze stage, an identification of non-value added activities contained in the process. It was found that there was a significant delay, especially in the announcement of the Final Project Briefing (TA) and filling in the focus of the TA study. By using the Cause-Effect Diagram method and 'Five Whys' technique, it is identified that one of the roots of the problem in the undergraduate program is the difficulty of students in finding research objects and lack of hard skills competencies. Meanwhile, in the Masters program, the main problem is the difficulty of students in time management.

Improvement Stage

After identifying the root of the problem, the improvement stage is done by proposing a solution. For undergraduate programs, the proposed alternative is that the department provides recommendations on research objects and facilitates certified training for students. As for the Masters Program, it is recommended to prepare a guidance schedule regularly so that students can be more directed in completing their studies.

Control Stage

Finally, at the Control stage, the proposed alternative during the improvement stage is considered to be included in a routine evaluation questionnaire. This evaluation aims to ensure that the solution that has been applied is functioning effectively and has a positive impact on the quality of graduates.

Conclusion

By applying the concept of Lean Six Sigma, the Department of Industrial Engineering can systematically identify and overcome existing problems, so that it is expected to improve the quality of graduates and meet BAN-PT standards. This better management enforcement will not only benefit students, but also the industry who will accept graduates who are more competent and ready to use.

Recommendations

Based on the analysis and application of Lean Six Sigma, the following recommendations are made:

The Department of Industrial Engineering should provide recommendations on research objects and facilitate certified training for undergraduate students.
The department should prepare a guidance schedule regularly for Masters program students to help them manage their time effectively.
A routine evaluation questionnaire should be conducted to ensure that the proposed solutions are functioning effectively and have a positive impact on the quality of graduates.

Future Research Directions

Future research should focus on evaluating the effectiveness of the proposed solutions and identifying areas for further improvement. Additionally, the application of Lean Six Sigma in other departments and institutions should be explored to determine its potential benefits and challenges.

Limitations of the Study

This study has several limitations, including:

The data used in this study is limited to the 2016 school year undergraduate program and the 2017 and 2018 school year Masters program.
The analysis and application of Lean Six Sigma are limited to the Department of Industrial Engineering.
The study does not consider the potential impact of external factors, such as changes in government policies or economic conditions, on the quality of graduates.

Conclusion

In conclusion, the application of Lean Six Sigma in the Department of Industrial Engineering has the potential to improve the quality of graduates and meet BAN-PT standards. The proposed solutions, including providing recommendations on research objects and facilitating certified training for undergraduate students, and preparing a guidance schedule regularly for Masters program students, are expected to have a positive impact on the quality of graduates. However, further research is needed to evaluate the effectiveness of these solutions and identify areas for further improvement.
