Abstract

Science subjects really need a learning model that makes students learn a lot from experience, not from verbal speeches and memorizing concepts given by the teacher. Experience can only be gained through practical activities and experiments which can ultimately improve students' science process skills. The reality in the field shows that physics experimental activities cannot be carried out optimally because a lot of equipment cannot be operated, the number of experimental sets is not enough and the equipment needed is quite expensive. The aim of this research is to increase teachers' skills in developing low-cost laboratory experimental kits by combining technology from video analysis and modeling tools with the research object being the physics MGMP teachers of Agam district. Implementation stages include providing training/workshops, practical implementation and evaluation of results. After carrying out this activity stage, the results obtained are video analysis products from participants and student worksheets. The results of this research can be analyzed and concluded that physics teachers' understanding and skills in carrying out video-based practical activities have increased due to limited practical equipment in the laboratory. The increase in participants' understanding can be seen from the results and their satisfaction with the implementation of laboratory experiment kit development activities based on video analysis and modeling tools. Therefore, improving these skills has a very good impact on teachers to increase learning variations that attract students' interest, and assist students in understanding Physics concepts correctly and being able to find their best potential

Abstract

Ikan merupakan sumber protein hewani yang penting bagi manusia, namun ikan rentan terhadap pembusukan. Oleh karena itu, diperlukan suatu metode yang cepat dan akurat untuk mendeteksi kesegaran ikan. Salah satu indikator kesegaran ikan adalah perubahan warna. Penelitian ini bertujuan untuk menguji karakteristik sensor warna TCS230 sebagai pendeteksi kesegaran ikan berdasarkan perubahan warna. Metode pengujian meliputi kalibrasi, pengukuran presisi, dan akurasi sensor TCS230 menggunakan lima variasi warna pada kertas uji, serta pengujian langsung pada sampel ikan segar, kurang segar, dan busuk. Hasil pengujian menunjukkan bahwa sensor TCS230 memiliki akurasi sebesar 98,83% dan presisi sebesar 98,3% dalam mendeteksi perubahan warna. Pada pengujian ikan, sensor berhasil mengidentifikasi kesegaran ikan berdasarkan perubahan warna kulit dan daging dengan konsistensi yang baik. Berdasarkan hasil tersebut, sensor TCS230 memiliki potensi yang baik sebagai pendeteksi kesegaran ikan yang cepat dan akurat.

Abstract

Udara mempunyai peranan yang sangat penting bagi kehidupan makhluk hidup, oleh karena itu udara sebagai sumber daya yang sangat penting harus dijaga dan dilindungi. Untuk mendapatkan udara yang sesuai dengan tingkat kualitas yang diinginkan maka pengendalian udara penting untuk dilakukan. Penelitian ini bertujuan untuk merancang dan membangun sistem monitoring kualitas udara yang mampu mendeteksi gas karbon monoksida (CO) dan partikel debu PM10 menggunakan sensor MQ-7 dan Sharp GP2Y1010AU0F. Sistem monitoring yang dikembangkan dirancang untuk memberikan hasil pengukuran secara langsung dengan cara membandingkan nilai fisis yang terukur oleh sensor dengan instrumen standar untuk evaluasi akurasi dan presisi. Implementasi sistem dilengkapi dengan interface aplikasi Blynk yang memudahkan monitoring data secara realtime. Hasil penelitian menunjukkan bahwa sensor yang digunakan pada sistem monitoring ini mempunyai tingkat linearitas yang baik dalam mengukur gas CO dan PM10. Spesifikasi perancangan sistem juga menunjukkan tingkat akurasi dan presisi yang tinggi dalam mengukur parameter suhu, kelembaban, karbon monoksida dan PM10.

Abstract

Based on observations and interviews with a science teacher at a junior high school in Pesisir Selatan Regency, it is known that there are still many science teachers who have not carried out practicum activities in scientific learning. Science kits are rarely used by teachers in science learning. The main reason is that the competence of science teachers in operating the science kit is still low. To improve the competence of science teachers in using KIT, it is very necessary to carry out activities to optimize the use of KIT for science teachers. The purpose of this study was to improve the competence of science teachers in using IPA KIT as a support for scientific learning. This type of research is a quasi-experimental design with a pretest-posttest using multiple choice test instruments at the beginning and at the end of the study. From the results of this study, it is known that there is an increase in the competence of science teachers in using science kits, with the percentage increase of 29.25%.
