Analysis of Supplier Relationship Performance and Supplier Relationship Improvement Using the DMAIC Method at XYZ Company

Abstract

Kopi merupakan salah satu komoditas ekspor utama Indonesia yang berkontribusi signifikan terhadap devisa negara dan sebagian besar dipasok oleh petani kecil. PT. Ujang Jaya International, sebagai perusahaan eksportir kopi, menghadapi tantangan dalam menjaga stabilitas pasokan akibat hubungan dengan pemasok yang masih bersifat informal dan kurang terstruktur, sehingga berdampak pada fluktuasi pasokan dan daya saing ekspor. Penelitian ini bertujuan untuk mengevaluasi kinerja hubungan pemasok menggunakan pendekatan Supplier Relationship Performance Measurement (SRPM) yang mencakup enam variabel, yaitu kepercayaan, daya tawar, transparansi, komunikasi, komitmen, dan keberlanjutan. Selain itu, metode DMAIC (Define, Measure, Analyse, Improve, Control) digunakan untuk merumuskan strategi perbaikan. Data diperoleh melalui kuesioner yang disebarkan kepada perusahaan dan pemasok serta divalidasi melalui wawancara mendalam. Hasil penelitian menunjukkan bahwa kinerja hubungan pemasok berada pada tingkat sedang, dengan kelemahan utama pada aspek komitmen dan daya tawar. Rekomendasi perbaikan meliputi penerapan kontrak formal, peningkatan komunikasi dan transparansi, serta pemberian insentif berbasis kinerja guna menciptakan kemitraan yang lebih berkelanjutan dan kompetitif dalam rantai pasok kopi global.

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. XYZ, a coffee-exporting company, faces challenges in maintaining supply stability due to informal, 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 strategies 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 moderate, with significant weaknesses in commitment and bargaining power. Recommended improvements include implementing formal contracts, enhancing communication and transparency, and introducing performance-based incentives. These steps are expected to foster a more sustainable and competitive partnership in the global coffee supply chain.
