Analisis Supplier Relationship Performance dan Perbaikan Hubungan Pemasok Menggunakan Metode DMAIC pada PT. Ujang Jaya International

Abstract

Coffee is one of Indonesia’s main export commodities, contributing significantly to national foreign exchange earnings. The majority of coffee supply comes from smallholder farmers across various regions. PT. Ujang Jaya International, a coffee exporting company, faces challenges in maintaining supply stability due to informal and unstructured relationships with its suppliers. This condition leads to fluctuating supply and weakens the company’s export competitiveness. This study aims to evaluate the supplier relationship using the Supplier Relationship Performance Measurement (SRPM) approach, which includes six key variables: trust, bargaining power, transparency, communication, commitment, and sustainability. Additionally, the study proposes improvement plans using the DMAIC method (Define, Measure, Analyze, Improve, Control). Data were collected through questionnaires distributed to both the company and suppliers, supported by in-depth interviews for validation. The findings indicate that the quality of the relationship is at a moderate level, with significant weaknesses in commitment and bargaining power. Recommended improvements include the implementation of formal contracts, enhanced communication and transparency, and performance-based incentives. These steps are expected to foster a more sustainable and competitive partnership in the global coffee supply chain.
