Experiment is important in physics to explain and describe a physical phenomenon and its characteristics. For this reason physics teachers should conduct the physics experiment activities to motivate students in learning and to improve scientific process skills, scientific attitudes, and student understanding in physics learning. However, in the experiment activities of physics were found many problems such as experiment equipment was insufficient, there is no equipment, equipment can�t operated well, and so on. An alternative solution to solve this problem was to do the video analysis and modeling tool tracker on physics teacher. The purpose of this research was to investigate the effects of the implementation the tracker video analysis and modeling tool on physics teachers. The research design was pretest and postest for one group sample. The sample of research was 26 physics teachers of Physics MGMP teacher in Agam district of West Sumatera. Instruments to collect the data consist of pretest and postest sheet, performance assessment sheet of video analysis product and questionnaires sheet of physics teachers. Data analysis techniques include descriptive statistical analysis, normality test, homogeneity test and paired comparison test for one group sample. From the data analysis, it can be stated that: 1). the average value of video analysis products from physics teachers is 85.10 and this value can be classified into very good category, 2). the average value of responses of physics teachers on training implementation of video analysis and tool modeling is 73.81 and this average value can be grouped into good category, and 3). the implementation of video analysis training of object motion video by using tracker software is effective to improve the understanding the physics MGMP teachers in Agam district on learning material of tracker video analysis and modeling tool, but the average value of understanding still in the low category.

Penyinaran matahari sebagai sumber energi yang penting bagi kehidupan merupakan salah satu parameter cuaca yang penting untuk diukur. Penelitian ini mendesain dan membuat sistem pengukuran intensitas dan durasi penyinaran matahari menggunakan mikrokontroller ATMEGA328 Arduino Uno dan satu buah sensor LDR yang pergerakannya diatur menggunakan motor stepper. Tampilan sistem menggunakan LCD dan PC. Data yang diukur disimpan secara otomatis dalam format *xls. Sistem memiliki ketelitian rata-rata pengukuran intensitas cahaya matahari sebesar 0.9993 dengan persentase ketepatan rata-rata ialah 98,79%. Pada pengukuran durasi penyinaran matahari, sistem memiliki ketepatan rata-rata pengukuran sebesar 93,876%.

Learning of physics according to the curriculum 2013 emphasizes the comprehensive achievement of student competence, so that the equality between soft skills and hard skills is formed. The role of learning materials especially physics subject is very important to support implementation of curriculum for physics learning. In fact, the knowledge and skills content of physics learning materials used students in school is more than attitude content. Development of physics learning materials integrated the values of emotional intelligence is the alternative solution of this problem. This research use Research and Development (R&D) method. This paper explains results of preliminary and main field testing of the physics learning materials integrated the values of emotional intelligence. This product has a validity value of around 85.83 or a very valid category. Based on data analysis, there are two results from this research. First, the practicality value of product according to teacher and student are an average score of 88.1 and 82 respectively or very high category. Second, the physics learning materials integrated emotional intelligence values is effective to improve the student competences in learning. The results of research indicate that the emotional intelligence value developed in physics material is feasible using in physics learning than it able to realize the comprehensive competence achievement.
