Tujuan penelitian ini adalah untuk mengidentifikasi etnosains dari berbagai daerah yaitu Lombok, Bali dan Medan yang dapat diintegrasikan dalam pembelajaran IPA di SMP. Metode yang digunakan untuk memperoleh data tentang etnosains dari daerah-daerah tersebut adalah melalui kaji literatur dan wawancara langsung dengan tokoh adat dan masyarakat di tiap daerah. Hasil penelitian menunjukkan bahwa terdapat beberapa etnosains yang teridentifikasi dapat diintegrasikan dalam pembelajaran IPA, yakni: 1) Bali, terdapat budaya penggarakan patung berupa makhluk raksasa menyeramkan (Ogoh-Ogoh) yang dapat dikaitkan dengan konsep usaha dan energi; 2) Lombok, terdapat tradisi Bau Nyale (menangkap cacing), dalam hal ini nyale merupakan cacing laut yang termasuk cacing bersekat (Annelida), sehingga tradisi ini dapat dikaitkan dengan konsep klasifikasi makhluk hidup, dan konsep nutrisi karena nyale banyak mengandung protein; 3) Medan, terdapat tradisi Erlau-lau atau siram-siraman untuk mendatangkan hujan, dapat dikaitkan dengan konsep penguapan, proses terjadinya hujan, hingga siklus air.

The purpose of this study was to determine the feasibility of physics learning tools based on cognitive conflict approach to improve students' scientific argumentation skills. The type of research used is Research and Development (R&D) with a 3D-based development model design consisting of 3 stages starting from Define, Design, and Develop. The product developed in this study is a learning device consisting of a syllabus, Learning Implementation Plan (RPP), Student Worksheets (LKPD), and test instruments. The feasibility of the learning device was obtained from the assessment of the validation questionnaire by the validator of physics lecturers and physics teachers. The assessment of the validation questionnaire produces qualitative and quantitative data. Qualitative data produces suggestions and inputs that are used as references to improve the learning tools developed. While the quantitative data is processed to get the value of validity and reliability. The quantitative data from the validation by the lecturers shows that the syllabus, lesson plans, and LKPD are in the very valid category and the test instrument shows a valid category. Meanwhile, the results of teacher validation showed that all the learning tools developed were in the very valid category. Data processing for reliability using the method Borich, known as the Percentage Agreement (PA). Reliability value of all learning tools, whether validated by lecturers or teachers, shows a reliable category because they have a value of more than 75%.

This study aims to produce appropriate and effective learning tools based problem-based learning model assisted by media kotak kartu misterius (KOKAMI) to improve students' problem solving skills in Physics. This study uses Research and Development (RnD) research with a 4D model consisting of four stages, namely Define, Design, Develop, and Disseminate. The tools developed in this study were the syllabus, lesson plans, LKPD, analysis of learning materials, problem solving ability test instruments, and KOKAMI learning media. The feasibility of the developed device was obtained based on the validity and reliability of the learning device. The validity of the developed device was obtained from a questionnaire assessment of six validators, namely three expert validators and three practitioner validators, then the validity of the device was analyzed using a Likert scale. The reliability of the developed device was obtained from the calculation of the percentage of agreement (PA) from the questionnaire assessment by six validators. The effectiveness of the device is obtained based on the analysis of the acquisition of N-Gain scores obtained from the assessment of the problem-solving ability test carried out by 15 students. Based on the results of the research that has been done, the average value of expert validity is 3.43 and practitioner validity is 3.68 in the very good category, then the average reliability of the device by expert validity is 91.83% and practitioner validity is 93.71% which indicates the device can be said to be reliable. Analysis of the calculation of the effectiveness of the developed device shows the acquisition of the N-Gain value in a limited trial obtained an average of 0.63 which indicates the medium category. So it can be concluded that the learning tools developed are effective.

Penelitian kali ini bertujuan untuk membuat alat ukur kecepatan bunyi dan menentukan cepat rambat bunyi melalui medium zat padat menggunakan sensor piezoelctric. Adapun medium uji zat padat yang digunakanadalah batang logam tipis dari tiga jenis bahan yang berbeda. Batang uji sepanjang 6 m terbuat dari aluminium, besi dan tembaga. Proses pengujian dilakukan dengan membentuk batang uji menjadi kumparan yang digulung di atas gabus yang berfungsi untuk meredam getaran dan gelombang bunyi. Hal ini dilakukan dengan asumsi bahwa gelombang bunyi hanya akan meambat melalui medium batang logam. Kumparan dihubungkan dengan plat besi pada salah satu ujungnya, kemudian dipukul dengan palu sebagai sumber bunyi. Ketika palu dipukul ke plat besi secara otomatis perhitungan waktu penjalaran gelombang dimulai kemudian waktu akan berhenti ketika sudah mencapai ujung yang lain yang telah terhubung dengan sensor piezoelctric, sehingga didapat waktu waktu penjalaran gelombang pada zat padat. Kemudian dihitung nilai cepat rambat gelombang bunyi pada medium zat padat tersebut. Hasil perhitungan kecepatan yang didapat akan dibandingkan dengan dengan nilai kecepatan refrensi dan dihitung persentase errornya.
