	abstract = {In the virtual laboratory learning process, students{\textquoteright} scientific abilities in solving a problem are very important to explore. This study aims to develop classroom-based authentic assessment instruments through virtual laboratory learning in chemistry to see an increase in students{\textquoteright} scientific performance. The research was conducted at a public high school in Langsa City with a sample of 11th-grade students Academic Year 2021/2022, the utilized subjects being a total of 118 students taken based on purposive sampling. The research data are needs analysis through interviews with chemistry teachers who have implemented technology-based learning, analyzing the feasibility of instruments through expert validation questionnaires before the learning process, and scientific performance through learning observation sheets during the learning process. The increase in students{\textquoteright} scientific performance data was then analyzed using the N-Gain formula and t-test to see the difference in improvement after the authentic assessment was applied. The results show that authentic assessment is feasible to use an increase in students{\textquoteright} scientific performance. From the small-scale test, the students{\textquoteright} scientific performance was a high category and there is a significant difference in improvement. The use of authentic assessment through virtual laboratories is expected to provide active learning solutions to improve student learning outcomes.},
