Abstract

PT XYZ faces the problem of not achieving production targets in five departments, especially in the Finishing Department with an achievement of only 54%. This study aims to identify the most dominant waste and provide suggestions for improvement. The methods used include interviews and giving 8 waste questionnaires to five respondents. Then, the most dominant type of waste was determined using a Pareto diagram. After that, root cause analysis was conducted using the 5 Whys method and suggestions for improvement were given. The results show that the dominant type of waste is waiting, caused by waiting for materials as needed, process queues due to the limited number of workers, and difficulty finding materials in an unorganized work area. The proposed improvements include improving communication with suppliers regarding material specifications, improving labor schedules and providing counseling and training on the application of the 5 S/R culture. With these proposed improvements, it is expected to increase the achievement of production targets in the Finishing department of PT XYZ.

Abstract

The Indonesian government is encouraging the digitalization of public procurement to strengthen the use of domestic products and services, including competency certification. The LSP Batik is a professional certification institution that assesses the competencies of batik artisans and communities. They face challenges due to limited digitalization and restricted access to certification information. This project aims to develop an e-catalog design for the certification schemes and to enhance the understanding of digital procurement. A Participatory Design approach was adopted, actively engaging both end-users and key stakeholders across all phases of the co-creation and evaluation process. The project culminated in the development of an e-catalog integrated with the government's e-procurement portal, designed to modernize the services of LSP Batik. The design evaluation yielded high suitability scores for illustration and contrast (100%), followed by the completeness of information (88%), and branding and clarity of information (75%). Furthermore, user assessment indicated a high degree of comprehension in product search functionality (100%), while understanding of product comparison (63%) and showcase development (50%) was moderate, suggesting areas for future improvement.
