ABSTRACT : The rapid development of technology is currently important to study in order to determine the magnitude of the impact of adolescent behavior on the understanding of Hinduism. Therefore, it is necessary to measure the understanding of Hinduism in SMA PGRI 4 and SMK PGRI 5 Denpasar. To determine the level of understanding of Hinduism, observations were made and questionnaires were distributed to respondents. The questionnaire as a tool for collecting data and the method used in measuring the level of students’ understanding of Hinduism is the Mamdani Fuzzy Logic method which is implemented through Matlab 6.1 software. The results show that 94% of Hindu youths have a very high understanding of Hindu religious teachings, while 6% have a very low understanding. Using Fuzzy Logic can produce information on understanding Hinduism that is accurate and can be used as an evaluation to improve spiritual and emotional intelligence in the future.
