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

This authoritative reference presents a comprehensive review of the evolution of plasma science and technology fundamentals over the past five decades. One of this field’s principal challenges has been its multidisciplinary nature requiring coverage of fundamental plasma physics in plasma generation, transport phenomena under high-temperature conditions, involving momentum, heat and mass transfer, and high-temperature reaction kinetics, as well as fundamentals of material science under extreme conditions. The book is structured in five distinct parts, which are presented in a reader-friendly format allowing for detailed coverage of the science base and engineering aspects of the technology including plasma generation, mathematical modeling, diagnostics, and industrial applications of thermal plasma technology. This book is an essential resource for practicing engineers, research scientists, and graduate students working in the field.
