Scaffolding Methodology Implementation for Training Program in an Engine Assembly Department of Indonesian Remanufacturing Company

Remanufacturing is a form of circular economy implementation that is crucial to drive the sustainability development goals. PT. XYZ, one of the most extensive remanufacturing companies in Indonesia aims to improve its competitiveness and sustainability by focusing on their human resources aspect, especially on the competencies of assembly mechanics. The challenge occurred when the learning development lead time is time consuming, thus found an urgent need for its optimization. In order to dealt with the challenge, this research is conducted by adopting the Scaffolding Methodology model of which consists of four stages, namely focused instruction, guided instruction, collaborative learning and independent learning. The training program emphasized not only on the enhancement of the curriculum and the practical concept, but also its training location and the adoption of E-Learning. Moreover, the use of scaffolding method as gradual release of responsibility framework has been deployed, as well as knowledge conversion in the form of assembly collaboration and re-layout of assembly lines. Finally, this study has succeeded in developing an integrated training program that able to generate a significant reduction in preparing mechanic's competencies.
