Indonesia is a democratic country where the majority of the population is Muslim. This constitution guarantees freedom of worship for all Indonesian people, according to their religion or belief. It was also stated that the state is based on faith in "Belief in the One and Only God" (former of the first precepts of Pancasila, the philosophy of the Indonesian state). This paper is the result of a mini-research to identify phenomena that occur in adolescents related to religious beliefs in everyday life. This belief is manifested through expectations and the learning process they experience. This study involved 268 students, 46 people (17.2%) were scholarship recipients from BAZNAS (zakat institution). The data shows that not all constructs (four statements) refer to religious beliefs, so they must be removed for further research. The results of the study showed a high level of religious belief, the routine of carrying out rituals of worship, so that belief as a source of life decisions can influence a person's learning process while studying. On the other hand, a person's faith in his religion can also affect the extent of a teenager's optimism in achieving his life goals. [For the full proceedings, see ED652261.]
