Abstrak Setiap perusahaan tentu memiliki kebutuhan akan suatu barang atau alat tertentu agar operasinya dapat berjalan dengan baik. Untuk memenuhi kebutuhan tersebut, diperlukan bagian yang disebut Procurement. Lembaga XYZ adalah sebuah lembaga pendidikan yang cukup terkemuka di Indonesia. Seperti halnya perusahaan atau lembaga lain, lembaga XYZ juga memerlukan procurement untuk mengelola dan menyediakan berbagai macam barang peralatan dan barang perlengkapan yang harus tersedia tepat waktu guna mendukung kegiatan belajar mengajar dan kegiatan administratif di dalamnya. Penulisan skripsi ini bertujuan menganalisis faktor-faktor yang dapat meningkatkan dan mengefektifkan kinerja bagian procurement dan merancang sistem eprocurement yang berbasiskan teknologi internet yang diharapkan dapat membantu meningkatkan efisiensi pengadaan barang dari segi biaya maupun waktu pada lembaga ini. Metodologi analisa yang digunakan adalah metode analisis dan perancangan sistem informasi berorientasi objek dengan bahasa perancangan UML (Unified Modeling Language), metode wawancara, studi lapangan dan studi pustaka. Penelitian ini menghasilkan sebuah situs web online yang diharapkan dapat membantu mempermudah proses pemesanan barang ke supplier. Kesimpulan dari hasil penelitian ini yaitu sistem e-procurement ini dapat meningkatkan kinerja pihak procurement, menghemat biaya serta memperlancar hubungan antara pihak procurement serta supplier sehingga dapat mempersingkat waktu yang dibutuhkan untuk melakukan proses pengadaan logistik pada lembaga XYZ.
