Penggunaan metode yang sama tidak selalu efektif untuk setiap pasien diabates, karena respons setiap individu terhadap penggunaan metode terapi dapat berbeda-beda. Pendekatan berbasis Machine Learning telah banyak digunakan untuk penanganan penyakit diabetes, baik untuk deteksi dini maupun proses perawatan pasien diabetes. Pada konteks penanganan pasien diabetes mellitus, pemilihan terapi yang tepat bagi setiap pasien sangat penting untuk dapat mencapai kontrol glikemik yang baik dan mencegah komplikasi jangka panjang. Permasalahan dalam penanganan pasien diabetes adalah menentukan model yang tepat untuk setiap pasien yang berbeda, sehingga pendekatan model berbasis domain fitur menjadi sangat penting untuk diterapkan.

Developing a knowledge management system is expected to maintain the integrity of examinees and reduce the risk of plagiarism. This research identifies user needs in business processes and maps them to relevant features based on previous research.
Methods: This research adopted a user-centered design methodology in developing interface design solutions, which consisted of four stages: understanding the context of use, specifying user requirements, designing solutions, and evaluating against requirements. Semi-structured interviews were used for data collection, and a system usability scale (SUS) questionnaire was employed for design solution evaluation.
Result: This research identified the needs of business processes in higher education in the context of exam proctors and mapped them to a suitable feature solution. Recommendations for information architecture and knowledge management system design implementation in higher education were also provided.
