This research is based on the Regulation of the Nuclear Energy Supervisory Agency of the Republic of Indonesia Number 2 of 2018 concerning Conformity Tests for Diagnostic and Interventional Radiology One component that must be tested with a minimum passing standard of ? 100 lux at a distance of 100 cm. Data collection is obtained at the Calibration Agency to obtain accurate results. The purpose of this tool, the Lux Meter is equipped with a distance sensor to measure the light intensity of a collimator lamp with an intensity that must be ? 100 within a distance of 100 cm from the light source. So, making a tool that can be used to measure the amount of collimator illumination is accompanied by measuring the distance, so that it can ensure the results are in accordance with the limits that have been determined with a Lux Meter equipped with a distance sensor using the BH1750 module and the HC-SR04 module. For testing the tool made, it was compared with a Standard Lux Meter with the HIOKI brand, an average error value of 0.021 at a distance of 50cm, an error of 00.020 at a distance of 100cm, and an error of 0.022 was obtained, while for testing the distance sensor it was compared with a Standard Meter with the FLUKE brand. The average percentage error value is 0.002 at a distance of 50cm, an error of 0.011 at a distance of 100cm, and an error of 0.008 at a distance of 130cm.

Tujuan dari penelitian ini adalah untuk membuat media pembelajaran animasi berbasis flash bagi siswa di SMK Ungaran Kanaan, serta meningkatkan minat siswa untuk belajar animasi. Metode yang digunakan adalah Research and Development, yaitu metode yang mengembangkan suatu produk tertentu seperti media pembelajaran berbasis animasi. Penelitian ini dilatarbelakangi oleh ditemukannya kurangnya media pembelajaran animasi di SMK Ungaran Kanaan khususnya pada kelas XI pelajaran animasi Multimedia

Mathematics is an applicable science and very close to human life, so mathematics is very important to learn from elementary school. However, the mathematics competence of elementary school students in Indonesia is relatively low. One of them is SD IT Cahaya Ummat which is located in Karangjati, Kecamatan Bergas, Kabupaten Semarang, the grade 6 students' average mathematics score is lower than other subjects. So far, learning is still conventional in nature with learning resources in the form of printed books, thus it is necessary to have learning innovations to increase students' interest in learning mathematics.The design of interactive media as a learning aid can be a solution to attract students' attention to be more focused when the teacher explains math material in class. When students feel interested and focused on learning, learning will be more effective so that students' understanding of the material presented by the teacher will also increase.Interactive learning media made with Adobe Flash CS5.5 to combine text, images, sound, and animation will make the application more attractive, so that students are more interested in learning mathematics with statistics material. The results of the validation score obtained from media experts are 34, material experts 39, and users 35, so this learning media product is classified as a very good category, so it is valid to be used.
