Abstract

The development of education needs to adapt to the needs of 21st century skills, including collaboration and problem solving. This study aims to analyze and describe the profile of Collaborative Problem Solving (CPS) online learning, as well as to describe the problem solving skills after learning. This research was conducted at SMA N 1 Gubug in class XI MIPA 1 for the academic year 2021/2022 with a qualitative descriptive method. CPS online learning is divided into virtual meetings using Microsoft Teams and discussions via text messages in WhatsApp. The research data was obtained through data observation’s, interviews, and written posttests. Data processing using a fixed comparison method with three stages, namely; data reduction, categorization, synthesis, and determination of hypotheses. The results showed that the role of the teacher appeared with almost the same frequency, namely as a motivator (37%), communicator (32%) and facilitator (31%). Students' problem-solving skills are dominated by the ability to plan and identify problems with the frequency of occurrence of 35% and 31%, respectively. The next two stages of problem solving, namely implementing the plan and checking back only appeared with a percentage of 19% and 15%.

Abstract

The learning model that is used in the learning process had an impact on the ability of students to analyze problems. The aim of this study was to use the SAVI learning model to increase the analytical student activity in physics in the second grade of senior high school. This study's design was quasi-experimental. This study used this research is purposive sampling because both schools have the same competency level. The data was collected through observation, tests, and documentation. The research was conducted in Jepara with control and experimental groups respectively. The data's validity is evaluated using normality and homogeneity tests. The observation sheet for assessing learning activities has a validation score of 4.39, which is considered very good. The results were proved by observation sheets of student activities, which showed that this strategy was more effective. The experimental group's score increased from 81.94 to 87.92, while the control group's score increased from 79.43 to 81.83. The test scores for the experimental and control groups were 84.93 and 80.62, respectively, indicating that SAVI learning model in this study was found to be effective in improving students' learning activities.

Abstract

Telah dilakukan suatu penelitian tentang analisis struktur bawah permukaan di daerah Trangkil, Gunung Pati, Semarang, Jawa Tengah berdasarkan data gaya berat. Latar belakang dari penelitian ini adalah bahwa daerah Trangkil merupakan daerah yang telah dinyatakan rawan longsor oleh Direktorat Geologi Tata Lingkungan. Penetapan daerah Trangkil sebagai daerah rawan longsor dinyatakan setelah pada tanggal 23 Januari 2014 daerah tersebut mengalami bencana longsor besar yang menyebabkan beberapa rumah rusak parah. Oleh karena itu, perlu dilakukan penelitian geoteknik yang memanfaatkan metode gravitasi atau gaya berat, sehingga struktur bawah permukaan daerah trangkil dapat diketahui. Metode yang digunakan dalam penelitian ini adalah metode gaya berat. Metode gaya berat adalah salah satu metode geofisika yang menggunakan disribusi parameter percepatan gaya berat di permukaan bumi. Faktor-faktor yang mempengaruhi nilai variasi percepatan gaya berat bumi antara lain densitas batuan (kerapatan massa), kondisi morfologi, pasang surut, udara bebas, bentuk bumi dan lain-lain. Variasi densitas bawah permukaan tanah adalah faktor yang sangat berpengaruh dalam penentuan penyebaran anomaly gaya berat secara geofisika. Pengumpulan data dilakukan dengan menggunakan alat Gravity Meter, yang selanjutnya dilakukan pengolahan data meliputi proses koreksi yaitu tahapan pengolahan data gaya berat hasil observasi di lapangan. Hasil Simple Bougier Anomaly (SBA) untuk anomaly pada daerah penelitian berkisar di antara 0,5 mGal – 7,5 mGal. Hasil Complete Bougier Anomaly (CBA) untuk anomaly pada daerah penelitian berkisar di antara 0,5 mGal – 7,5 mGal.

Abstract

Teknologi Digital dan Kecerdasan Buatan dengan sasaran utama siswa SMA Negeri 1 Parepare. Tujuan kegiatan pengabdian ini meningkatkan pemahaman konsep matriks pada siswa SMA Negeri 1 Parepare melalui pengembangan dan implementasi aplikasi kalkulator matriks berbasis web yang interaktif dan mudah diakses. Selain itu, kegiatan ini juga bertujuan untuk meningkatkan literasi digital siswa dalam penggunaan aplikasi matematika spesifik sebagai alat bantu belajar mandiri. Metode utama yang digunakan dalam kegiatan ini adalah pelatihan dan pendampingan. Pelatihan akan diberikan kepada siswa SMA Negeri 1 Parepare mengenai penggunaan aplikasi kalkulator matriks berbasis web. Pelatihan akan mencakup pengenalan fitur-fitur aplikasi, langkah-langkah penggunaan aplikasi untuk berbagai operasi matriks, dan pemanfaatan fitur visualisasi dan umpan balik otomatis. Pendampingan berkelanjutan akan diberikan kepada siswa selama periode implementasi aplikasi. Pendampingan meliputi bantuan teknis, konsultasi tentang strategi pembelajaran, dan evaluasi penggunaan aplikasi. peningkatan pemahaman konsep matriks, peningkatan keterampilan literasi digital, pengembangan media pembelajaran interaktif, serta peningkatan kemandirian belajar siswa. Selain itu, program ini diharapkan dapat memberikan manfaat jangka panjang bagi komunitas sasaran dan menjadi model yang dapat direplikasi di wilayah lain
