Sustainable supplier development of wood product manufacturing

The plywood industry is one of the manufacturing industries whose raw materials are based on the sustainability of natural resources. The challenges that arise are difficulties in obtaining raw materials especially Sengon wood, low quality wood, delays in delivery, and a critical land crisis in forest areas. This drives the need for supplier assessments that focus on sustainability and recommends developmental steps and ensures supplier compliance with requested sustainability standards. This study aims to formulate supplier performance evaluations based on sustainability aspects. The steps taken are through supplier segmentation using the Triple Bottom Line (TBL) approach to ensure supplier criteria are aligned with sustainability aspects. Furthermore, using TOPSIS, the selected suppliers will be determined according to the established criteria. The supplier development strategy is developed based on the characteristics of each supplier segmentation, namely compiling a written guidebook; company visits to transfer knowledge and share experiences; company reviews; regular oversight for the provision of feedback; and long-term contracts. This study contributes a framework for addressing raw material challenges and applying sustainability principles in supplier selection and development, aligned with the company's mission of sustainable growth.
