COVID-19 attacked Wuhan city in December 2019 where the number of cases increased rapidly, but the clinical information of infected patients was limited. One of the negative effects related is the education sector. COVID-19 also changed the learning model drastically, all learning activities were carried out online. This causes students difficulties in learning. The purpose of the research was to analyze the difficulty factors of physics education students in distance learning during the COVID-19 pandemic. This type of research is descriptive research. Data collection techniques using a questionnaire. Research subjects were 80 students from Physics education at FKIP Riau University. The results of research online learning difficulties come from two factors, namely external and internal factors. External factors include non-current internet networks and very many student assignments. Internal factors related to students' learning difficulties, students generally have difficulty communicating and discussing both fellow students and with lecturers, misconceptions occur, difficulties in summarizing the material, and eye discomfort due to cellphone and laptop radiation.
The purpose of this study was to develop a sea water purifier and test the validity of a sea water purifier so that it can be used as a medium for high school physics learning on global warming material. The development model carried out is the ADDIE model. The ADDIE model consists of Analysis, Design, Development, Implementation and Evaluation. The data obtained in the form of qualitative and quantitative data. Qualitative data is used to obtain the value of preliminary analysis and validation of tools used in learning. Quantitative data is used to obtain empirical test values by comparing the results of measuring tools made with standard measuring instruments. Based on the results of the empirical test, it was found that the fresh water produced by the developed seawater purifier has good quality because it meets water standards that are suitable for consumption. Based on the research conducted, it was found that the average fresh water produced was 50.33 mL from 1 liter of seawater which was dried for 6 hours per day, and the decrease in salt content of seawater after using this seawater purifier that utilized solar power was 100%. . Based on the results of expert validation which refers to the functionality of the tool, learning elements, ease of use, aesthetics and construction of the tool, the average value of the validity index is 3.78 with a very high category. So it can be concluded that the developed seawater purifier is valid and can be used as a medium for learning Physics on global warming material.Keywords: sea water purifier, learning media, global warming.ABSTRAK Tujuan penelitian ini adalah untuk mengembangkan alat pemurni air laut dan menguji validitas alat pemurni air laut agar dapat digunakan sebagai media pembelajaran Fisika SMA pada materi pemanasan global. Model pengembangan yang dilakukan adalah model ADDIE. Model ADDIE terdiri dari Analysis, Design, Development, Implementation dan Evaluation. Data yang diperoleh berupa data kualitatif dan kuantitatif. Data kualitatif digunakan untuk mendapatkan nilai analisis pendahuluan dan validasi alat yang digunakan dalam pembelajaran. Data kuantitatif digunakan untuk memperoleh nilai uji empiris dengan membandingkan hasil ukur alat yang dibuat dengan alat ukur yang sudah standard. Berdasarkan hasil uji empiris diperoleh bahwa bahwa air tawar yang dihasilkan oleh alat pemurni air laut yang dikembangkan memiliki kualitas yang baik karena memenuhi standar air yang layak dikonsumsi. Berdasarkan penelitian yang dilakukan, diperoleh rata-rata air tawar yang dihasilkan 50,33 mL dari 1 liter air laut yang dijemur selama 6 jam per harinya, dan penurunan kadar garam air laut setelah menggunakan alat pemurni air laut yang memanfaatkan tenaga surya ini sebesar 100%. Berdasarkan hasil validasi pakar yang mengacu pada keberfungsian alat, unsur pembelajaran, kemudahan penggunaan, estetika dan konstruksi alat diperoleh nilai rata-rata indeks validitas 3,78 dengan kategori sangat tinggi, sehingga dapat disimpulkan bahwa alat pemurni air laut yang dikembangkan bernilai valid dan dapat digunakan sebagai media pembelajaran Fisika pada materi pemanasan global.Kata kunci: alat pemurni air laut, media pembelajaran, pemanasan global.
Fisika merupakan bidang ilmu yang berhubungan dengan praktikum. Dalam praktikum perlu didukung oleh bahan ajar, salah satunya adalan penuntun praktikum. Praktikum merupakan strategi pembelajaran yang memungkinkan siswa secara empiris melatih kemampuan kognitif, psikomotor, dan afektif secara bersamaan dengan menggunakan fasilitas laboratorium. Penuntun praktikum berbasis guided inquiry diharapkan dapat membantu mahasiswa dalam praktikum. Tujuan dari penelitian ini adalah menganalisis awal akhir untuk merancang penuntun praktikum berbasis guided inquiry. Model pengembangan R and D yang digunakan adalah ADDIE model yaitu tahap analisis kebutuhan salah satunya analisis awal akhir. Jenis penelitian ini termasuk penelitian kualitatif yang termasuk penelitian deskriptif. Teknik pengumpulan data menggunakan kuesioner. Penelitian dilakukan di Universitas Riau. Hasil dari penelitian yaitu dosen memiliki kinerja mengajar yang baik namun perlu menemukan penuntun praktikum sehingga tercipta suasana pembelajaran yang berpusat ke mahasiswa. Penuntun praktikum disusun berdasarkan analisis kebutuhan yaitu fasilitas praktikum perlu dirancang sesuai dengan tujuan praktikum.
This research aim was to test the validity of the integrated physics module for natural disasters and mitigation for middle schools. This research uses research and development (R&D) with the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). Specifically for this research, it is limited to development. Specifically for this research, it is limited to development. The analysis in the analysis phase includes material analysis and regional potential analysis. The material analysis results show that several materials can be integrated with natural disaster materials, namely particle dynamics, heat and displacement, and static and dynamic fluids. At the design stage, two stages were carried out: the physics module's design and the validation instrument's preparation. At the development phase, validation of the physics module is carried out. Improvement or revision of the module product based on the validation sheet and suggestions from the experts involved. The research data is quantitative data based on the data from the validity of the physics module. The study used a validation assessment sheet instrument. The validity data analysis technique uses a Likert scale. The results of the validation of the physics module for aspects of content, construct, linguistics, and graphics obtained an average value of 89.8% which is categorized as valid. Therefore, the integrated physics module for natural disasters and mitigation that has been designed is declared suitable for use in physics learning according to the material and level of middle school education and can be tested for practicality and effectiveness.
Siswa SMP mengalami kesulitan belajar dalam mata pelajaran IPA karena minat, motivasi, kebiasaan belajar, intelegensi dan kosentrasi yang rendah. Selain itu, mata pelajaran IPA juga dinilai abstrak salah satunya pada materi listrik. Tujuan dari penelitian yang dijelaskan pada artikel ini adalah untuk mengembangkan media pembelajaran yang valid berupa game “An Intel’s Science Missions” berbasis Borland Delphi 7 pada materi listrik statis untuk siswa kelas IX SMP. Pengembangan media pembelajaran ini dilakukan sebagai solusi dari kesulitan belajar IPA akibat pelajaran IPA yang abstrak serta kurangnya minat dan motivasi siswa dalam pembelajaran IPA. Jenis penelitian yang digunakan adalah research and development (R&D) menggunakan model ADDIE yang terdiri dari lima tahap yaitu tahap analisis (Analyse), tahap perancangan (Design), tahap pengembangan (Development), tahap implementasi (Implementation), dan tahap evaluasi (Evaluation). Teknik pengumpulan data berbentuk lembar validasi yang diberikan kepada tiga validator. Teknik analisis data yaitu dengan cara menghitung skor penilaian validasi dengan menggunakan indeks validitas formula Aiken’s V. Hasil penelitian menunjukkan bahwa media pembelajaran game “An Intel’s Science Missions” berbasis Borland Delphi 7 pada materi listrik statis untuk siswa kelas IX SMP yang dikembangkan memenuhi kriteria valid dari aspek yang divalidasi meliputi aspek kelayakan desain, aspek kelayakan pedagogi, aspek kelayakan konten, dan aspek kelayakan teknikal dengan indeks validitas Aiken’s V sebesar 0.88.
