The Department of Physics has three academic programs, those are : Bachelor Degree of Department of Physics in the number of student is about 350, Master Degree of Physics which established recently on 2011 in the number of student is 24 person, and Diploma Program of Electronics & Instrumentation in the number of student is 85 person. Over the years the number of student who approved in Bachelor Degree of Department of Physics is ever increasing, this is proving that Department of Physics is more and more interested by student applicant. By means of staff instructor composition in the Department of Physics who has been titled as Doctor (Postgraduate Degree) is about 60% and in the short future will increase be 80%, so the quality of learning in the Department of Physics is ever increasing. Research in the Department of Physics is divided into five fields group, those are : Radiation Physics, Medical Physics, Material Physics, Electronical Instrumentation, and Geophysics which are supported by competent staff of each field. Several staff have a lot of hit upon research fund either fund from government and private suitably by each competence. So that produced the innovative eruditions and become innovation source to the development of the most recently knowledge.
