<![CDATA[ABSTRAK Kebutuhan mahasiswa akan tempat tinggal sementara di sekitar Universitas Negeri Manado terus naik seiring bertambahnya jumlah mahasiswa baru tiap tahunnya. Banyaknya pilihan kamar kost yang punya karakteristik beda-beda sering bikin calon penghuni bingung menentukan mana yang cocok dengan kebutuhan dan preferensi mereka. Penelitian ini dibuat untuk merancang dan membangun Sistem Pendukung Keputusan (SPK) pemilihan kamar kost berbasis web dengan memakai metode Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). Metode pengembangan sistemnya memakai Waterfall, yang jalurnya lewat analisis kebutuhan, perancangan, implementasi, pengujian, lalu pemeliharaan sistem. Data penelitian dikumpulkan lewat observasi, wawancara, studi pustaka, dan dokumentasi. Pengambilan keputusan didasarkan pada empat kriteria utama: harga, fasilitas, kebersihan, serta keamanan. TOPSIS dipakai buat menentukan peringkat alternatif kamar kost dengan menghitung jarak ke solusi ideal positif dan jarak dari solusi ideal negatif. Hasil penelitian memperlihatkan kalau sistem yang dibangun bisa mengelola data kost, data kriteria, bobot penilaian, dan kasih rekomendasi kost secara terstruktur serta objektif. Pengujian memakai Black Box Testing menunjukkan semua fungsi sistem berjalan sesuai kebutuhan pengguna. Jadi, sistem ini membantu pengguna mendapatkan rekomendasi kamar kost yang lebih tepat, efektif, dan sesuai kriteria yang sudah ditentukan, sehingga keputusan bisa diambil lebih cepat dan akurat. ABSTRACT The demand for temporary student housing near Manado State University continues to rise alongside the annual increase in the number of new students. The wide variety of available boarding rooms—each with distinct characteristics—often leaves prospective tenants unsure about which option best suits their needs and preferences. This study aims to design and develop a web-based Decision Support System (DSS) for selecting boarding rooms, utilizing the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. The system development follows the Waterfall model, comprising stages of requirements analysis, design, implementation, testing, and maintenance. Research data were gathered through observation, interviews, literature reviews, and documentation. Decision-making is based on four primary criteria: price, facilities, cleanliness, and security. TOPSIS is employed to rank boarding room alternatives by calculating their distances from both the positive ideal solution and the negative ideal solution. The results demonstrate that the developed system can effectively manage boarding room data, criteria, and assessment weights, while providing recommendations in a structured and objective manner. Black Box Testing confirms that all system functions operate in accordance with user requirements. Consequently, the system assists users in obtaining accurate and effective boarding room recommendations based on predefined criteria, thereby facilitating faster and more precise decision-making.]]>
