Measurements with using  micrometer and vernier caliper is one of the subject taught in high school level. The problem faced is the small size of the tool making it difficult for students when the teacher demonstrates the tools. The solution to solve this problem is by develop a learning media with the use of Construct 2 software. The development of this media follows the 4D model which consists of 4 stages of development that is defining, designing, developing, and disseminating. Validation test by experts and feasibility questionnaires by users of teachers and students have been done to determine the feasibility of the learning media. Aspects assessed by the expert is the aspect of media feasibility in terms of visual communication design, software engineering aspects and aspect in term of learning contents. The media feasibility test by users is done in SMA Muhammadiyah 2 Magelang and SMAN 1 Pecangaan Jepara. The data obtained show that the media created have very good categories in terms of visual communication design and learning contens, as well as good categories in terms of software engineering aspects. The media created are also rated very well by students and teachers.

Analisis Peta Konsep dan Konsepsi Paralel Fisika Gelombang Calon Guru Fisika Alethea, Alethea; Sarwi, Sarwi; Linuwih, Suharto

Penelitian ini mengungkap gambaran pemahaman mahasiswa pada konsep fisika gelombang melalui analisis peta konsep dan konsepsi paralel. Subjek penelitian terdiri atas 5 orang mahasiswa semester 3 dan 6 orang mahasiswa semester 5  prodi pendidikan fisika. Data dikumpulkan dengan menggunakan  instrumen peta konsep dan tes tertulis konsepsi paralel dengan teknik triangulasi. Teknik analisis data yang digunakan yaitu deskriptif persentase untuk data kuantitatif, sedangkan untuk data kualitatif yaitu analisis satuan konsep dan analisis konsepsi paralel. Penelitian menyimpulkan bahwa (1) hasil analisis peta konsep menunjukkan rendahnya persentase pemahaman mahasiswa mengenai keterkaitan konsep getaran-gelombang-energi, hal itu disebabkan karena ketidaklengkapan konsep-konsep yang tercantum dalam peta konsep buatan mahasiswa dan kurangnya kemampuan bahasa mahasiswa dalam menggunakan kata penghubung yang tepat dalam membentuk proporsi, (2) ditemukan adanya konsepsi paralel pada topik penjalaran gelombang bunyi di udara dan sifat penjalaran gelombang elektromagnetik. Konsepsi paralel cenderung terjadi pada mahasiswa dengan tingkat semester yang lebih tinggi. Intuisi yang muncul dari pengalaman akademik yang lebih luas serta pemahaman konsep fisika gelombang yang tidak tepat berpotensi memunculkan konsepsi paralel pada pemikiran mahasiswa.   This research reveals description of the student’s understanding  upon waves concept of physics by concept map analysis and parallel conception. Subjects of research consisted of 5 students in third semester and 6 students in fifth semester of physics education study program. Data collected by  using concept map instrumen and written test of parallel conception with triangulation technique. The data analysis technique was descriptive percentage for quantitative data, while for qualitative data was unit concept analysis and parallel conception analysis. The study concluded that (1) the analysis results of concept map showed low percentage of student’s understanding at the linkages of vibration-waves-energy, it’s caused by the uncomplete concepts that listed in student’s concept map and the lack of  students’ languange abilities in used of liaison word when forming a proportion, (2) parallel conceptions were founded at the propagation of sounds waves in the air and the propagation of electromagnetic waves. Parallel conceptions were tend to accur at students with higher semester level. The appeared intuition from the larger of academic experiences and the uncorrect understanding of waves concept of physics potentially bring up parallel conception at student’s thought.

One of the policies developed in the curriculum 2013 is to provide services to students according to their talents, interests, and learning abilities. A teacher is required to be able to provide an Independent Learning Activity Unit or Unit Kegiatan Belajar Mandiri (UKBM) for students. The goals of this research are to develop physics UKBM of work and energy based on contextual learning, to know the feasibility and readability of UKBM, and to know the improvement of student?s understanding about work and energy concepts. The used method in this research is Research and Development (R&D). The research steps consist of study of potential and problems, data collection, product design, expert validation, product revisions, small-scale trials, product revisions, and large-scale trials. One Group Pretest-posttest was used as the trials design. The subject of trials is 10th grade student of SMA Negeri 1 Kendal in 2018/2019 school year. The results of the research are the characteristics of UKBM of work and energy based on contextual learning according to the guidelines for developing UKBM and aspects of contextual learning. The core activities of the UKBM include four learning activities, which are the concept of work, the concept of the relationship of work and energy change, and the concept of the Law of Conservation of Mechanical Energy. The learning process was arranged using the Problem Based Learning model by presenting physics problems in daily life. UKBM of work and energy was declared very feasible with a percentage score of eligibility of 96%. The readability test result of 77% showed that UKBM was easy to understand. Based on the results of large-scale trials, the application of UKBM in learning can improve student's understanding of concepts with the gain of 0.49 in the middle improvement category.

This study aims to describe teachers' perceptions of practicum in physics learning, the implementation and obstacles of implementing physics practicum in online learning during the Covid-19 pandemic in the even semester of the 2019/2020 academic year and the odd semester of the 2020/2021 academic year. The research method is descriptive quantitative. The instrument used was a google form questionnaire. Samples were taken using simple random sampling technique, obtained 50 SMA / MA physics teachers in Central Java and East Java. The results showed that all teachers have the same perception that the application of practicum in learning physics is important. However, during the online learning period the teachers rarely applied practicum. Some teachers even argue that they haven't thought about how to implement online practicum. More than 50% of teachers have tried to do practicum during online learning. The types of practicum used are various, ranging from virtual laboratories, simulations, video demonstrations and hands-on. The implementation of practicum in online learning experiences various obstacles, both hardware (practicum material tools, computers / notebooks, smartphones, networks) and software, namely practicum procedures that are not understood by students and students' activeness control mechanisms.
