Abstract
This study used a descriptive quantitative approach to collect data on students^ needs regarding innovative virtual learning resources based on green chemistry for cation analysis instruction. The study population consisted of all 182 students in the Chemistry Department for the 2025/2026 academic year. A total of 50 students were selected as the research sample. Data were collected using needs analysis questionnaires for both faculty and students, each consisting of 10 statements. The research results based on the faculty needs analysis indicate that conventional learning still faces challenges (75%), yet there is a very strong perception regarding the effectiveness of virtual laboratories (85%), and the importance of integrating green chemistry (87.5%). The student needs analysis also indicates limitations in laboratory practice due to a lack of equipment, materials, and time (80%). Students expressed a high need for innovative digital learning resources (80%) and believed that virtual laboratories can enhance higher-order thinking skills (80%), as well as a high level of interest and urgency (80%) among students for innovative virtual laboratory learning resources based on green chemistry as a safe and environmentally friendly solution for laboratory practice.
