Learning media supporting practical learning in vocational high school (VHS) is urgent during the COVID-19 pandemic. All VHS competencies, including land surveying techniques, cannot support students with the existing online learning facilities. This study explained the development and impact of using multimedia simulation on the learning outcomes of VHS students. The Alessi and Trollip development model with planning, design, and development phases were used to create the multimedia simulation. The participants in this research included teachers, students, material experts, and media experts. The pre-test and post-test of practical learning outcomes, as well as questionnaires, are selected to collect research data. The results based on the experts’ and teachers’ validation, and students’ assessment indicated that the multimedia simulation was 'feasible' to be used in practical learning. Based on students’ post-test results, the average score in the experimental class increased more than the average score in the control class. These findings suggested that learning land surveying techniques using multimedia simulation is more effective than classes without using multimedia simulation. Teachers and educational researchers might use this study as an example for creating learning materials to raise the standard of instruction in VHSs.
