ABSTRAK Perusahaan manufaktur saat ini dituntut untuk memperhatikan aspek lingkungan. Hal ini disebabkan karena adanya tekanan konsumen, meningkatnya kesadaran masyarakat, peningkatan polusi, dan adanya peraturan pemerintah tentang lingkungan. CV Annet Sofa menyadari pentingnya melakukan peningkatan performansi lingkungan, dengan cara bekerjasama dengan supplier yang memiliki performansi ekonomi dan lingkungan yang baik. Dengan melakukan kerjasama dengan green supplier maka perusahaan dapat memberikan jaminan kepada konsumen bahwa bahan baku yang digunakan oleh CV Annet Sofa adalah bahan baku yang ramah lingkungan sebab disupply oleh supplier yang memiliki performansi lingkungan yang baik. Penelitian ini menggunakan pengintegrasian metode Decision Making Trial and Evaluation Laboratory (DEMATEL) dan Grey-Analytical Network Process (GreyANP). Pengintegrasian metode digunakan untuk menghilangkan bias dalam menentukan ranking green supplier sehingga dihasilkan keputusan yang tepat. Metode DEMATEL digunakan untuk menentukan hubungan keterkaitan yang terbentuk antar subkriteria. Metode ANP digunakan untuk menentukan bobot dari subkriteria. Metode Grey digunakan untuk menghilangkan bias dalam penilaian. Hasil penelitian ini didapatkan urutan peringkat green supplier dengan bobot, supplier 1 (4,624), supplier 2 (1,848), supplier 3 (3,15), dan supplier 4 (1,007). Kata kunci : Pemilihan Green Supplier, Green Purchasing, DEMATEL, GREY-ANP, Kriteria Ekonomi, Kriteria Lingkungan
