Penelitian ini dilakukan untuk menghasilkan suatu media edukasi perlindungan anak untuk mengurangi perilaku kekerasan pada anak. Perlindungan anak merupakan permasalahan yang harus mendapatkan perhatian dari setiap pihak. Untuk meningkatkan perlindungan terhadap anak diperlukan suatu media edukasi yang dapat digunakan dengan mudah oleh setiap pihak, baik oleh orang tua, guru, maupun anak tersebut. Media edukasi yang dihasilkan dalam penelitian ini adalah dalam bentuk buku cerita bergambar. Berdasarkan hasil uji validasi oleh tiga orang ahli diperoleh hasil sebesar 95% dalam kategori sangat baik. Hasil uji lapangan pada 15 orang tua, 14 orang guru, dan 11 orang anak juga diketahui bahwa media edukasi buku bergambar sangat baik dan dapat dipahami dari segi cover, isi, dan tampilan buku cerita. berdasarkan hasil analisis data maka dapat disimpulkan  bahwa buku cerita seri perlindungan anak sangat baik, sehingga dapat digunakan untuk meningkatkan pengetahuan orang tua, guru, dan anak tentang perlindungan anak sehingga dapat mengurangi perilaku kekerasan pada anak.

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.

Rupat Island located at a coastal area of Riau Province, generally coastal areas are identical with the availability of clean water. The low availability of clean water has a negative impact on all sectors. The water used by students and teachers at SMA Negeri 1 Rupat comes from a ring well which tastes salty and brackish. Problems in the health sector are the availability of clean water that is suitable for consumption, education is insufficient equipment for Physics Experiments, in the economic field, family spending increases due to the availability of bottled water, and the field of community empowerment has not maximized the use of natural resources. The solution for this aspect is technological innovation that is able to meet the need for clean water in the long term by utilizing existing potential, one of which is the manufacture of a sea water purifier, a giant measuring 4x4 meter. The tool's fundamental working principle is to evaporate the air first and then collect the condensed water to separate the mineral salts and contaminants from the seawater. The author has made a seawater purifier measuring 48x38 cm as a medium for high school physics learning in 2021 with a TKT 5.

This is a developmental study that began with observations of some early childhood children in Siak Sri Indrapura, Indonesia, who lacked reading readiness. Seeing the potential of Malay folklore, a learning media for Malay folklore pictorial stories was developed. The process of creating media begins with the determination of the story and theme, followed by the creation of designs and product models. Validator assessment is feasible and may be used to determine a child's readiness for reading. To determine the effectiveness of the media, this study used a quantitative method with a two-group post-test design. According to the t-test results, a t-observed value of -8,175 with a significance value of 0.000 indicated that there was a difference in reading readiness between the experimental and control groups, indicating that the Malay folklore pictorial story media was effective for early childhood reading readiness in Siak Sri Indrapura.
