This study aims to analyze the activities of computational practicum using logger pro software to improve student graphic representation in understanding the oscillation material. The sample are 35 students of class X Mipa 3 SMA 1 Bae in 2016/2017 decided by purposive sampling technique. The research instrument is a harmonic oscillation sheet and a description test that measures the ability of graphical representation. The research method used mixed method with concurent embeded design. Analysis of research data using comparative test t paired sample test and N - Gain test of student scores. Students found some synchronous oscillation characteristics between the results of the lab and the results of the analysis of six graphs from the plot logger pro. The results of pretest and post-test average score are respectively 20.85 and 43.73. Description of comparative test statistic yields tcount> ttable which means there is significant difference between pre-test and post-test value data, and N-Gain test is 0.29 which means there is increasing value in low category. It shows computational activity using logger pro, effectively improving students' ability in multiple graph representations to understand the characteristics of harmonic oscillations.

This study aims to determine the level of understanding of the concept, the level of misconception, and the factors causing misconceptions that occur in students of class XI MIPA 2 in SMA Negeri 1 Purwodadi. This research is a mixture of qualitative and quantitative research. The instrument used in this study was a check-list; written test questions that are equipped with student confidence tables in answering questions or the Certainly Of Response Index (CRI); and interview guide sheets. The data collected is then analyzed to determine the students who will take the interview. Interviews were conducted with 9 students who had different levels of concept understanding. Furthermore, data from written test results and interviews are interpreted together with triangulation techniques to obtain conclusions from the research results. The analysis showed that the level of understanding of the concept of class XI students in SMA Negeri 1 Purwodadi on optical equipment material had a percentage of concept understanding of 16%, misconceptions of 55%, and did not understand the concept of 29%. The highest misconception is in the matter of the nature of mirrors and convex lenses in everyday events and special rays in convex mirrors with a percentage of 61%. Factors causing misconceptions among students include examples of questions given by teachers less varied, teachers are too fast in explaining the material, student worksheets are incomplete, there are no practicums that support learning, students do not pay attention, and do not record the material delivered by the teacher, students do not learn before the test takes place, students are not careful in answering questions, and students only memorize the material while learning without understanding the basic concepts of the material.

The type of the research is Research and Development (R&D) with ADDIE design. The data collection methods used were test, response questionnaire, and interviews. This research was conducted at SMAN 1 Jatisrono online using google form. A total of 20 essay questions were designed to be pre-trial tested in class XI MIPA 5 and produce ten appropriate essay questions then used for trial test in XI MIPA 1 and 2. The test instruments were declared worthy based on three categories, they’re expert judgment, reliability testing, and student responses. The percentage of eligibility of experts is 85.42%, it shows that the instrument is suitable for use. This instrument is declared reliable for use, with a reliability value of 0.71. The difficulty index of the test is on the medium and easy level with moderate discrimination index.
