The objectives of this research are to 1) find out the profile of student's learning motivation in Physics class measured by aspects such as Attention, Relevation, Confidence, and Satisfaction; and 2) measure the percentage of each learning motivation aspect such as Attention, Relevation, Confidence, and Satisfaction contributed to students' learning motivation in Physics class. The sample of this research is 90 students from XI class of Science Program. The data was collected through questionnaire and observation. The questionnaire was analyzed using descriptive quantitatively while the observation sheet was analyzed qualitatively. The results show that: 1) the student's learning motivation can be categorized into high, average, and low; and 2) the percentage of each learning motivation aspects are Attention (59,86%), Relevance (57,08%), Confidence (55,28%), and Satisfaction (60,14%). To conclude, the average level of students' learning motivation for Physics is in the medium and low category caused by the lack of students' interest in learning Physics.
