Analisis Pemilihan Green Supplier Oli Engine dengan Metode Delphi-AHP di PT Kalimantan Prima Persada, Jakarta Timur

Abstract

PT Kalimantan Prima Persada sebagai perusahaan jasa penambangan memerlukan oli engine untuk mendukung kegiatan operasional. Tingginya konsumsi oli engine yang menghasilkan limbah serta tuntutan kepatuhan regulasi lingkungan mendorong perusahaan menerapkan pemilihan pemasok berbasis green supplier. Penelitian ini bertujuan mengidentifikasi kriteria pemilihan green supplier, menentukan bobot prioritas, dan memilih pemasok terbaik menggunakan metode Delphi dan Analytical Hierarchy Process (AHP). Metode penelitian menggunakan pendekatan kualitatif dan kuantitatif dengan jenis data primer dan sekunder. Data primer diperoleh melalui wawancara pakar internal untuk memvalidasi kriteria dan subkriteria pemilihan pemasok. Kriteria kualitas mencakup kesesuaian spesifikasi, stabilitas viskositas, masa pakai, dan daya netralisasi asam. Kriteria harga mencakup harga produk, efisiensi biaya perawatan, dan biaya operasional perjam. Kriteria pengiriman mencakup ketepatan waktu, waktu tunggu, dan ketersediaan stok. Kriteria keamanan mencakup ketersediaan lembar data keselamatan, keamanan kemasan, dan kepatuhan K3KOLH. Kriteria moral mencakup komitmen, responsif, dan keterbukaan informasi. Kriteria lingkungan mencakup sertifikasi ISO 14001, layanan pengelolaan limbah, kemasan ramah lingkungan, dan penggunaan armada rendah emisi. Pembobotan dilakukan untuk memilih pemasok terbaik dari tiga alternatif pemasok, yaitu PT X, PT Y, dan PT Z. Hasil penelitian mengidentifikasi terdapat enam kriteria utama, yaitu kualitas (0,35), harga (0,21), pengiriman (0,15), lingkungan (0,13), keamanan (0,10), dan moral (0,07). Berdasarkan analisis, PT X terpilih sebagai pemasok dengan bobot tertinggi (0,50), diikuti PT Y (0,28), dan PT Z (0,22).

PT Kalimantan Prima Persada as an integrated mining services company requires engine oil to support operational activities. High oil consumption that generates waste, along with environmental compliance demands, drives the company to implement green supplier selection. This study aims to identify green supplier selection criteria, determine priority weights, and select the best supplier using the Delphi and Analytical Hierarchy Process (AHP) methods. The research method used qualitative and quantitative approaches with primary and secondary data. Primary data were obtained through interviews with internal experts to validate selection criteria and sub-criteria. Quality criteria included specification suitability, viscosity stability, service life, and acid neutralization capability. Price criteria included product price, maintenance cost efficiency, and hourly operating costs. Delivery criteria included timeliness, lead time, and stock availability. Safety criteria included safety data sheet availability, packaging safety, and K3KOLH compliance. Moral criteria included commitment, responsiveness, and information transparency. Environmental criteria included ISO 14001 certification, waste management services, eco-friendly packaging, and low-emission fleet usage. Weighting was conducted to select the best supplier among three alternatives: PT X, PT Y, and PT Z. The results identified six main criteria: quality (0.35), price (0.21), delivery (0.15), environment (0.13), safety (0.10), and moral (0.07). Based on the analysis, PT X was selected as the best supplier with the highest weight (0.50), followed by PT Y (0.28) and PT Z (0.22).
