PT XYZ adalah salah satu perusahaan yang memproduksi berbagai macam jenis plastik dengan kebutuhan kapasitas bahan baku kurang lebih 4 sampai 6 ton setiap harinya. Untuk memenuhi kebutuhan yang besar tersebut, manager pembelian membutuhkan suplai bahan baku lebih dari satu supplier, di mana saat ini, dalam mencari dan menentukan supplier bahan baku, perusahaan hanya bergantung kepada manager pembelian. Keputusan pemilihan supplier tersebut berdasarkan ingatan manager pembelian saja dan kriteria yang digunakan belum distandarisasi (dapat berubah-ubah). Melihat masalah tersebut, dapat dilihat bahwa ketersediaan informasi yang tepat memegang peranan penting untuk kelancaran produksi dari PT XYZ. Untuk mengatasi masalah tersebut, dibuatlah sebuah sistem rekomendasi dengan menggunakan metode TOPSIS yang mampu membantu manager pembelian dalam memberikan urutan list (ranking)supplier terbaik berupa prioritas terhadap solusi ideal dengan pemberian bobot yang dinamis dari skala 1 (prioritas terendah) sampai 5 (prioritas tertinggi) dari enam kriteria pemilihan supplier yang disesuaikan dengan kebutuhan PT XYZ. Berdasarkan hasil pengujian sistem rekomendasi menggunakan metode TOPSIS, manager pembelian dapat memperoleh hasil rekomendasi supplier dari supplier terbaik sampai supplier terburuk, dapat menentukan dan mengatur tingkat kepentingan dari enam kriteria pemilihan supplier beserta kapasitas bahan baku yang dibutuhkan oleh PT XYZ.
PT XYZ is a company that manufactures various types of plastic with a large capacity of raw materials for about 4 until 6 tons each day. To complete their daily needs, purchasing manager needs more than one supplier. Now, in order to find and decide raw material suppliers, the company relies only on purchasing manager. Choice of the supplier is based on purchasing manager's memory and those criterias have not standarized by the company. Based on these problem, we can conclude that information plays an important role for PT XYZ. To overcome these problems, PT XYZ made a recommendation system using TOPSIS method that will help purchasing manager to list the recommended supplier based on the priority of the ideal solution with scored with scale 1 for lowest priority until 5 for the highest priority. It is based on the criterias met by PT XYZ. Based on the test result using TOPSIS method, purchasing managers can obtain the recommendation of the best suppliers until the less recommended suppliers along with the raw material capacity that needed by PT XYZ.
