Abstract

Consistency in coffee bean quality is essential for maintaining flavor stability and production efficiency in coffee-based beverages. However, quality evaluation in small-scale coffee industries is often subjective and lacks a structured decision support system. This study aims to develop a decision support model for evaluating coffee bean quality using a Multi-Criteria Decision Making (MCDM) approach by integrating the CRITIC (Criteria Importance Through Intercriteria Correlation) and CoCoSo (Combined Compromise Solution) methods. The CRITIC method is employed to determine objective criterion weights based on data variability and inter-criteria correlations, while the CoCoSo method is used to rank alternatives. A total of 15 coffee bean alternatives were evaluated using seven criteria: price, availability, aroma, taste, color, texture, and caffeine content. The weighting results indicate that color (0.215) and price (0.191) are the most influential criteria in the evaluation process. The ranking results show that alternative A9 achieved the highest preference score (K = 4.1634), followed by A7 (K = 3.5747) and A6 (K = 3.4920). These results demonstrate that coffee beans with strong performance across sensory and physical attributes tend to achieve higher rankings. The proposed CRITIC–CoCoSo model provides a systematic, objective, and practical decision support tool that can assist small to medium-scale coffee industries in selecting high-quality raw materials, improving product consistency, and enhancing production efficiency.

Abstract

Perkembangan teknologi informasi mendorong pelaku usaha untuk memanfaatkan sistem penjualan berbasis digital guna meningkatkan efektivitas pemasaran dan pelayanan kepada konsumen. Glam Beauty Studio merupakan toko yang bergerak di bidang penjualan produk kecantikan, namun proses penjualannya masih dilakukan secara langsung sehingga jangkauan pemasaran menjadi terbatas. Penelitian ini bertujuan merancang antarmuka aplikasi e-commerce berbasis mobile yang sesuai dengan kebutuhan pengguna. Metode yang digunakan adalah Research and Development (R&D) dengan tahapan meliputi identifikasi potensi dan masalah, pengumpulan data, desain produk, validasi desain, revisi desain, dan uji coba produk. Pengumpulan data dilakukan melalui observasi, wawancara, dan studi pustaka. Hasil penelitian menghasilkan prototype antarmuka yang terdiri atas halaman login, halaman utama, katalog produk, keranjang belanja, dan halaman pembayaran. Prototype kemudian divalidasi oleh pihak manajemen Glam Beauty Studio dan memperoleh hasil bahwa rancangan antarmuka berada pada kategori sangat layak untuk dikembangkan ke tahap implementasi. Rancangan yang dihasilkan diharapkan dapat menjadi acuan dalam pengembangan aplikasi e-commerce, mempermudah proses transaksi, memperluas jangkauan pemasaran, serta meningkatkan efisiensi pelayanan kepada pelanggan.
