Abstract

The increase in production capacity at the valve manufacturing company has led to a significant rise in the volume of liquid waste, while the company does not yet have an internal Wastewater Treatment Plant (WWTP). As a result, the company must incur additional costs to pay third parties for wastewater management. Therefore, selecting the right WWTP vendor is a crucial step to ensure that wastewater treatment is carried out in accordance with environmental standards and applicable regulations. This study aims to determine the criteria and alternative WWTP vendors, as well as to obtain their priority rankings using the Simple Additive Weighting (SAW) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) methods. Data were collected through literature studies, questionnaires, and interviews with three key respondents: the Procurement Supervisor, the Quality, Health, Safety, and Environment (QHSE) Supervisor, and the Head of Production. The analysis results show that reputation is the top priority criterion with a weight of 0.632, followed by technical aspects (0.546) and administrative aspects (0.465). Financial and environmental aspects rank next with weights of 0.455 and 0.389, respectively. Based on the TOPSIS method, the best vendor alternative suited to the company’s needs is PT. Harum Tirta Jaya (A4), with a score of 0.637. This study is expected to support the company in making more accurate and objective decisions in selecting a WWTP vendor. Keywords: WWTP, vendor selection, SAW, TOPSIS, valve manufacturing production. Peningkatan kapasitas produksi pada perusahaan manufaktur valve production menyebabkan kenaikan signifikan dalam volume limbah cair, sementara perusahaan belum memiliki Instalasi Pengolahan Air Limbah (IPAL) internal sehingga perusahaan perlu mengeluarkan biaya untuk membayar pihak ketiga dalam mengelola limbah carinya. Oleh karena itu, pemilihan vendor IPAL yang tepat menjadi langkah penting untuk memastikan pengolahan limbah dilakukan sesuai standar lingkungan dan regulasi yang berlaku. Penelitian ini bertujuan untuk menentukan kriteria dan alternatif vendor IPAL, serta memperoleh urutan prioritasnya menggunakan metode Simple Additive Weighting (SAW) dan Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). Pengumpulan data dilakukan melalui studi literatur, kuesioner, dan wawancara dengan tiga responden kunci, yaitu Procurement Supervisor, Quality, Health, Safety, and Environment (QHSE) Supervisor, dan Head Production. Hasil analisis menunjukkan bahwa kriteria aspek reputasi menjadi prioritas utama dengan bobot 0,632, diikuti oleh aspek teknis 0,546 dan aspek administratif yakni 0,465. Aspek keuangan dan aspek lingkungan berada di posisi selanjutnya dengan bobot 0,455 dan 0,389. Urutan vendor terbaik sesuai kebutuhan perusahaan berdasarkan metode TOPSIS diperoleh PT. Harum Tirta Jaya (A4) sebagai alternatif unggulan dengan nilai 0,637. Penelitian ini diharapkan dapat membantu perusahaan dalam mengambil keputusan yang lebih tepat dan objektif untuk pemilihan vendor IPAL. Kata Kunci: IPAL, pemilihan vendor, SAW, TOPSIS, manufaktur valve production.
