Abstract

The background of this research  not all students like physics learning. This is caused by students' lack of understanding of physics learning material. The students' incomprehension can be seen when the learning process takes place, some students are embarrassed to ask even though basically the students do not understand the material presented by the teacher in front of the class. This type of research is Quasi Experiment with research design in the form of Design Group Control. Data on physics learning results are seen in two domains, namely the cognitive and affective domains. In the cognitive domain, the average experimental class has an average of 67.37 while the class has an average of 60.76. Learning outcomes in the affective domain obtained from the assessment of student activity sheets had an average of 79 in the experimental class and 74 in the control class. Based on the results of the analysis of hypothesis testing with the F test, it was found that t count = 1.64, and t table = 2.00, where if –t table < t count < t table then the hypothesis is rejected. So it can be concluded that the use of cooperative learning model type Group Investigation does not affect the learning outcomes of physics students of class XI MIPA SMAN 1 Enam Lingkung.

Abstract

Penelitian ini  bertujuan untuk melihat pengaruh karbon aktif dari batang jagung untuk penjernih air.   Tahap pengarangan (karbonisasi)  di variasikan dengan suhu 400 oC, 500oC, dan 600oC masing-masing selama 1 jam, 2 jam dan 3 jam.  Tahap aktivasi dengan menggunakan NaOH selama 1 jam Hasil analisis menunjukkan bahwa temperatur yang berbeda memberikan pengaruh pada karakteristik karbon aktif yaitu kadar air, kadar abu, PH dan XRF. Karbon aktif yang baik adalah karbon aktif yang telah memenuhi standar atau persyaratan yang ditetapkan, yaitu Standar Nasional Indonesia (SNI). SNI yang digunakan adalah SNI 06-3730-1995 untuk arang aktif teknis. Karbon aktif yang digunakan untuk penjernihan air adalah karbon yang disediakan pada suhu 600o C.  Pengujian  karbon aktif diterapkan pada penjernihan air sungai, dengan melihat bau, warna dan PH sebelum dan sesudah di filter dengan karbon aktif.

Abstract

At this time many learning models are used, where students learn, work, and interact in small groups. Based on the results of observations at SMAN 9 Padang class XI MIPA, students need a development of teaching materials that can help students to solve problems in learning. The purpose of this research is to develop teaching materials in the form of student worksheet based on problem based learning that are valid & practical for class XI MIPA SMAN 9 Padang.This type of research is included in development research or Research and Development (R&D) with a 4-D model. The 4-D model consists of four stages, namely define, design, develop, and disseminate. At the disseminate stage, it is not carried out due to time and cost limitations. In this study, the research instruments used were validity and practicality sheets. The results showed that the PBL-based LKPD developed was categorized as valid with a percentage of 85.93%. Then the PBL-based LKPD developed was categorized as very practical with a percentage of 85.32%.

Abstract

Alat ukur medan magnet digital yang dijual di pasaran saat ini memiliki harga yang relatif mahal, maka dibuatlah alat ukur medan magnet yang sederhana dengan fungsi yang sama dengan alat ukur medan magnet yang dijual di pasaran. Alat ukur ini terdiri dari lima bagian utama yaitu adaptor, selenoida, sensor efek hall, arduino uno dan OLED. Alat ukur medan magnet yang dibuat akan digunakan untuk mengetahui hasil pengukuran medan magnet terhadap variasi jarak selenoida, medan magnet terhadap jumlah lilitan kawat dan arus listrik pada selenoida, dan perbandingan pengukuran medan magnet terhadap jumlah lilitan kawat dan arus listrik pada selenoida menggunakan alat ukur acuan. Hasil pengukuran medan magnet terhadap jarak menunjukkan bahwa semakin dekat jarak sensor dengan lilitan maka semakin besar medan magnet yang terbaca oleh sensor. Hasil pengukuran medan magnet terhadap jumlah lilitan dan arus listrik menghasilkan medan magnet yang besar apabila jumlah lilitan magnet semakin banyak dan arus yang dibesikan semakin besar. % error untuk medan magnet terhadap jarak, jumlah lilitan dan arus listrik sebesar 14.60 %, 1.42 %, dan 0.44 %.

Abstract

AbstractFundamental physics is one subjects for Physics Education’s Department in STKIP PGRI West Sumatra. For supporting the course and geting a good result it require the lecturer’s note like module. The developed a lecturer’s note is a module based guided inquiry that is expected to make students more active, creative and critical thinking as well as skilled in the discovery of the facts in Physics. Guided inquiry is a learning model which there are some activities that are scientific, students submit ideas before the topic studied, then investigate a phenomenon or phenomena. After that, the student explained that based on existing facts and compare them scientifically. This type of research is research and development using a Plomp’s model is passing through the stages: (1) the initial investigation (preliminary research), (2) design and realization (prototyping phase), and (3) testing and assessment (assessment phase). On the preliminary research, curriculum analysis will be doing, so students analysis, and analysis of the concept. On prototyping phase the module for the Physics at the fluid is designed. Next, we get the formative evaluation that includes self evaluation, prototyping (expert reviews, one-to-one and small group). We get the validity at this stage. The research data was obtained through the validation module sheet, which then produces a valid module.Keywords: validity, modules, guided inquiry, fundamental physics, fluid AbstrakFisika Dasar merupakan salah satu mata kuliah Program Studi PendidikanFisika di STKIP PGRI Sumatera Barat. Untuk mendukung perkuliahan dan mendapatkan hasil belajar yang bagus maka dibutuhkan bahan ajar berupa modul. Bahan ajar yang dikembangkan merupakan modul yang berbasis guided inquiry yang diharapkan mampu membuat mahasiswa lebih aktif, kreatif, dan berfikir secara kritis serta terampil dalam penemuan fakta-fakta dalam Fisika Dasar. Guided inquiry adalah model pembelajaran yang didalamnya terdapat beberapa kegiatan yang bersifat ilmiah, mahasiswa menyampaikan ide-ide sebelum topik tersebut dipelajari, kemudian menyelidiki sebuah gejala atau fenomena. Setelah itu, mahasiswa menjelaskan berdasarkan fakta-fakta yang ada dan membandingkannya secara saintifik. Jenis penelitian yang digunakan adalah penelitian pengembangan (research and development) menggunakan model Plomp yaitu yang melewati tahapan: (1) investigasi awal (preliminary research), (2) perancangan dan realisasi (prototyping phase), dan (3) ujicoba dan penilaian (assessment phase). Pada tahap preliminary research dilakukan analisis kurikulum, analisis mahasiswa, dan analisis konsep. Pada tahap prototyping phase dilakukan perancangan modul untuk mata kuliah Fisika Dasar pada materi fluida. Setelah itu dilakukan langkah formative evaluation yang meliputi self evaluation, prototyping (expert reviews, one-to-one, dan small group). Pada tahap ini dilakukan validitas. Data penelitian ini diperoleh melalui lembar validasi modul, yang kemudian menghasilkan modul yang valid.Kata-kata kunci: validitas, modul, guided inquiry, fisika dasar, fluida

Abstract

Tujuan dari kegiatan pengabdian ini adalah untuk mengimplementasikan hasil penelitian pada  sekolah mitra. Mitra dari kegiatan pengabdian ini adalah SMA PGRI 4 Padang.  Latar belakang dari kegiatan pengabdian ini adalah masih terbatasnya keterserdiaan modul praktikum untuk menunjang kegiatan praktikum. Selain itu belum terpenuhinya semua peralatan laboratorium guna menunjang pembelajaran teori. Sasaran utama kegiatan pengabdian kepada masyarakat ini adalah peserta didik kelas XII pada mata pelajaran fisika dasar. Pelatihan yang dimaksud adalah penerapan modul elekronika dasar pada kegiatan praktikum. Kegiatan ini diikuti oleh 25 peserta didik kelas XII. Pelaksanaan kegiatan peserta didik membimbing kegiatan praktikum mengikuti tahapan modul secara berkelompok dan dilanjutkan dengan diskusi dan evaluasi. Hasil kegiatan ini sangat bermanfaat bagi perserta didik guna meningkatkan pemahaman konsep dan kompetensi peserta didik guna mendukung pembelajaran teori.
