Abstract

ABSTRAKParameter-parameter fisika gunungapi diungkap dengan metode geofisika. Survei kakas gravitasi dan magnetik  yang menghasilkan anomali positive bagi medan gravitasi dan magnetiknya, mengungkap struktur statis bawah permukaannya. Analisis tremor volkanik mengungkap dinamika internalnya. Gerakan-gerakan (aliran) fluida magma di dalam gunungapi menjadi sumber getar yang memancarkan gelombang seismik yang di sebut tremor volkanik. Lokasi, migrasi, daya pancar, bentuk geometri sistem pipa-kantong magma, periodisasi, model matematis dan sebagainya. Gempa volkanik yang disebabkan aktivitas magma dapat dijadikan indikator. Hasil pengeplotan posisi hiposenter dan episenter terhadap gempa volkanik yang terjadi, juga dapat mengungkap struktur statis bawah permukaan gunungapi. Kata Kunci : parameter-parameter fisika gunungapi; struktur statis bawah permukaanbawah permukaan ABSTRACTUsing methods of geophysics, physical parameters of volcano are described. Gravity and magnetic surveys yield positive anomaly on their fields, which can be interpreted as an accumulated material beneath the surface with certain values of its mass density and magnetic susceptibility. Analysis of volcanic tremor at the volcano to the knowledge of its internal dynamics. Fluid magma movements inside a volcano acts as source of vibrations which radiate sesmic wave called volcanic tremor. Location, migration, radiation power, geometry of magma chamber-pipe system, periodicities, mathematical models, etc. Volcanic earthquakes caused by magma activity can also be used as indicators. The results of the hypocenter and epicenter position of the volcanic earthquake that occurred, can also reveal the subsurface static structure of the volcano. Keywords : physical parameters;subsurface static structure

Abstract

Pelatihan Pembuatan Video Pembelajaran untuk Mahasiswa Pendidikan Fisika telah dilakukan secara daring. Kegiatan pelatihan ini bertujuan untuk melatih mahasiswa calon guru pendidikan fisika dalam pembuatan video pembelajaran sebagai luaran dari kegiatan Pengenalan Lingkungan Persekolahan (PLP). Kemajuan perkembangan teknologi memicu dunia pendidikan untuk terus pula berkembang. Keberadaan media sebagai penunjang pembelajaran juga menjawab kebutuhan zaman. Melalui program Pengenalan Lingkungan Persekolahan mahasiswa calon guru dituntut untuk dapat mampu memahami kegiatan pembelajaran secara langsung di sekolah. Agar dapat menyelesaikan program PLP mahasiswa harus membuat luaran video pembelajaran sehingga perlu diadakan pelatihan membuat video pembelajaran. Metode yang digunakan adalah metode ceramah dan tutorial penggunaan hardware dan software editing berbasis smartphone dan PC yaitu VN editor dan Filmora x. Luaran yang diharapkan adalah mahasiswa pendidikan fisika dapat memahami dan membuat video pembelajaran menggunakan software tersebut. Setelah kegiatan ini, mahasiswa diharapkan memperoleh wawasan dan keterampilan dalam pembuatan video pembelajaran untuk membuat luaran kegiatan Pengenalan Lingkungan Persekolahan (PLP).

Abstract

This study aims to determine the practicality of physics learning tools using blended learning model with video assistance on momentum and impulse materials to improve problem solving ability of students. This research is development research, where researchers have developed learning tools with valid categories to further see the practicality of the devices developed after testing. The research design used is a 4D model consisting of define, design, develop and disseminate. The tools developed consist of a syllabus, lesson plans, student worksheets, teaching materials, learning videos, and problem-solving ability assessment instruments. The research instrument used was a student response questionnaire and an observation sheet on the implementation of learning. The results of the analysis show that the device meets the very practical criteria seen based on the positive response of students to learning reaching 97.48% in the very practical category, and the learning implementation observation sheet reaches an average of 93.77% in the very practical category. This shows that physics learning tools using a blended learning model with video assistance on momentum and impulse materials are very practical to improve problem-solving ability of students

Abstract

Kegiatan pengabdian pada masyarakat (PkM) ini bertujuan memberikan pelatihan kepada para guru dalam melaksanakan penelitian tindakan kelas (PTK), menyusun karya ilmiah, dan melakukan publikasi karya ilmiah hasil penelitian ke dalam jurnal nasional. Partisipan yang terlibat dalam kegiatan PkM ini adalah para guru di SMA Negeri 1 Kopang yang berjumlah 39 orang. Metode yang digunakan untuk mencapai tujuan kegiatan adalah pendidikan dan pelatihan, dimana dilakukan serangkaian kegiatan in service training (IST) dan on service training (OST). Kegiatan in service training (IST) dilakukan dengan menggunakan pendekatan andragogis yang mengedepankan metode ceramah, diskusi, dan presentasi. Hasil kegiatan IST telah meningkatkan pemahaman guru tentang konsep PTK, karya tulis ilmiah, dan publikasi ilmiah. Selanjutnya, kegiatan on service training (OST) dilaksanakan pada saat guru menyusun karya ilmiah dalam bentuk artikel yang siap dipublikasi dalam jurnal nasional. Kurun waktu pelaksanaan kegiatan mulai dari persiapan sampaia dengan pelaporan adalah dalam 6 (enam) bulan. Akhirnya, melalui serangkaian kegiatan PkM yang telah terlaksana (melalui mekanisme IST dan OST), para guru yang terlibat dalam kegiatan pelatihan telah memperoleh pemahaman dan kemampuan dalam melaksanakan penelitian tindakan kelas (PTK), dan menyusun karya tulis ilmiah yang siap dipublikasi dalam jurnal nasional. Secara umum, kegiatan PkM telah berjalan dengan lancar dengan terpenuhinya target tujuan yang diharapkan dalam kegiatan PkM ini. Classroom Action Research and Scientific Writing Training for Teachers Abstract This community service activity (PkM) aims to provide training to teachers in carrying out classroom action research (CAR/PTK), compiling scientific papers, and publishing scientific research results in national journals. The participants involved in this PkM activity were the 39 teachers at SMA Negeri 1 Kopang. The method used to achieve the objectives of the activity is education and training, where a series of in-service training (IST) and on-service training (OST) activities are carried out. In service training (IST) activities are carried out using an andragogic approach that prioritizes lecture, discussion, and presentation methods. The results of IST activities have increased teachers' understanding of the concept of PTK, scientific papers, and scientific publications. Furthermore, on service training (OST) activities are carried out when the teacher composes scientific papers in the form of articles that are ready to be published in national journals. The period of implementation of activities starting from preparation to reporting is 6 (six) months. Finally, through a series of PkM activities that have been carried out (through the IST and OST mechanisms), the teachers involved in the training activities have gained understanding and ability in carrying out classroom action research, and compiling scientific papers that are ready to be published in national journals. In general, PkM activities have been running smoothly with the fulfillment of the goals expected in this PkM activity.

Abstract

This study aims to determine the effectiveness of physics learning tools using blended learning model with video assistance on momentum and impulse materials to improve problem solving ability of students. The learning tools were developed using a 4D model which includes the stages of define, design, develop, and disseminate. Learning tools developed in the form of syllabus, lesson plans, student worksheets, learning videos, and problem solving ability instruments in the form of descriptions with a total of 5 questions. The research data was obtained from the results of a limited trial in the tenth grade MIPA 4 SMAN 1 Mataram with a total of 33 people. The data obtained from the next study were tested for the value of n-gain to find out the improvement in problem solving abilities. The results showed that the overall value of n-gain was 0.66 in the medium category. In addition, the n-gain analysis of each problem solving indicator shows that the indicators of recognizing problems and planning strategies have increased with the n-gain value being in the medium category, while the indicator implementing strategies and evaluating solutions has increased with the n-gain value being in the high category. These results indicate that the physics learning tools using blended learning model with video assistance on momentum and impulse materials is effective to improve problem solving ability of students.
