One of the important branches of science on an international scale is scientific literacy. This study aimed to increase the science literacy knowledge of elementary school students on the material of the solar system. This study uses the ADDIE type Research and Development (R&D) method, starting from analysis, design, development, implementation, and evaluation. Expert testing of a learning product was carried out by users of the Planetarium Glass application, namely grade VI students of SDN Patengteng 2. The results of this media trial on 22 respondents showed 80% effectiveness. This research instrument uses an online questionnaire to users to determine the effectiveness of this learning media. The final result of the Planetarium Glass application media based on augmented reality is an application format that can be used by utilizing an android-based smartphone. This media provides information about the material of the solar system in the form of 3D virtual animation (3 dimensions) accompanied by an explanation of each object in audio form and is equipped with an application usage module. This media is designed to facilitate students' understanding in understanding the material of the solar system effectively and efficiently because students can see directly the material conveyed via the smartphone they use. Learning using the Planetarium Glass application can be used as an alternative learning media in increasing science literacy knowledge of elementary school students, especially in Madura.

This research aims to determine the product quality of the Menu Harianku application and recommend improving the quality of the application based on the ISO/IEC 25010:2011 model with 6 characteristics in product quality dimensions namely Functional Suitability, Performance Efficiency, Usability, Reliability, Security, and Portability. ISO/IEC 25010:2011 standard was chosen because of its very suitable characteristics for measuring software quality. Starts with identifying the problem, Design quality, Testing performance quality, and making application improvement recommendations. According to technical characteristics of Functional Suitability, of 97 test cases, there were 11 failed. Performance efficiency of Mobile and Desktop devices scores 86% of the improvement criteria. Reliability Hosting is only accessible in Asian (Japan) and European locations (all) for no more than 20 VUs. Security with Medium-level vulnerabilities. The portability of the application runs well on 6 Desktop & Mobile browsers. According to users the characteristics of Functional Suitability with a percentage of 84.1%, Performance efficiency at 84%, and Usability at 83.5%. As for the application recommendations related to the results of application quality testing that can be used in improving the quality of the Menu Harianku application.
