Seeing the current condition of education that the creation and development of new works in the field of technology continue to run, there should be no more obstacles not to create and innovate. A learning innovation can be pursued by applying strategies, methods, and cutting- edge teaching tools to enable a more productive teaching and learning process (Firmadani, 2020). Teaching materials are a set of teacher and student auxiliary materials to learneaching materials are distinguished based on their form and how they work. Depending on the format of printed instructional materials, listening resources, and listening materials, teaching materials based on how they work are audio, video, and other teaching materials (Nurafni et al., 2019) in (Mukhlis et al., 2020). Currently, teaching materials are not only conventional but can be digital-based, easily accessed for learning (Komariah et al., 2022). The choice of appropriate teaching materials and maximal media usage is one of the crucial elements required to enhance the high standard of learning for students (Wiyono et al., 2021). With the sudden emergence of the covid-19 epidemic, educational institutions must incorporate virtual education. The impact is that students' learning styles have changed to all online because they have to adapt to the distance learning system in the covid-19 situation. This condition is carried over to the present, where students tend to be tied to using smartphones in their daily activities, including in the learning process. Changes in students mailto:khaeranisudirman42801@gmail.com mailto:usman@umsrappang mailto:antiimaya57@gmail.com Khaerani, K., M, U., & Nurmayanti, N. (2023). Development of Science E-modules on Solar System Materials Based on Android for Junior High School Students. Indonesian Journal of Instructional Media and Model, 5(1), 58-68. doi:https://doi.org/10.32585/ijimm.v5i1.4169 59 learning styles, in this case, the tendency of students to use smartphones, present being challenged to educators in carrying out instruction. So this makes teachers innovate more by making Android-based media (Khasanah et al., 2020). For educators to facilitate the learning process, there must be access to flexible and innovative technology (Ahmed et al., 2020). One form of solution is to present learning media that is easily accessible (practical) and creative (entertainment content themed on learning concepts) by students with Android-based media (Sari, 2019). Learning media is a crucial component of the educational process and is used extensively in information and communication technologies (Yunus & Fransisca, 2020). Students can respond more readily to learning media when properly processed (Hasiru et al., 2021). Android-based media is one of the teaching tools that can keep up with the growth of information technology (Faqih, 2021). Due to students' propensity to use smartphones for a variety of daily activities, teachers need to provide access to Android-based media utilizing smartphones so that students can learn flexibly. Seeing these conditions, the process of distributing content in the context of e-modules to enhance student learning is demonstrated. Electronic modules (e-modules) are electronic versions of learning tools designed using software according to student needs (Alpiani et al., 2022). E-modules are interactive and serve as online educational resources to aid in learning (Pramana et al., 2020). On a smartphone, it is simple to access the Solar System e-module. Regarding the research findings (Astalini et al., 2019) learner can easily learn about the topic when using e-modules compared to printed modules. The making of e-modules is expected to be a student handbook that provides easy access to material and a flexible learning process (Dewi & Lestari, 2020). Smartphones are electronic devices that facilitate human communication (Isma et al., 2022). According to (Mahuda et al., 2021) smartphones are a modern learning medium that uses mobile devices that can offer the ability to innovate in various activities in their use. Learning using smartphones is a practical choice of learning tools because students are more inclined to use them. This can foster independent and practical learning for students (Usman et al., 2021). The effective smartphone usage in the classroom affects students' performance in learning (Syifa, 2020). Learning is a process that aims to achieve learning outcomes as much as possible (Winata, 2021). One of the breakthroughs in supporting learning is innovative aids. Such us e-modules can be packaged using the Smart Apps Creator (SAC) application, which has many exciting features that support the development of interactive teaching materials (Pebriani et al., 2022). SAC is software with output that can be used on laptops, smartphones, and tablets (Amalia, 2023). SAC is also supported by facilities that can load sound, images, videos, and even moving animations. E-modules using SAC can be accessed offline so that it does not cost much (Ilman Abi & Sujatmiko, 2022). Using e-modules packaged using SAC can foster student motivation and enthusiasm for learning because it is (Nurmayanti et al., 2021). Accordingly, using Android- based media within the learning process, particularly SAC, can boost students' engagement in learning (Suryaningtyas et al., 2020). The e-module developed with SAC is an application with economic value reflected in ease of use, so that it can be used indefinitely in terms of function and flexibility (Khasanah & Rusman, 2021). The appearance of learning media created using SAC is similar to an entertainment application so that students no longer believe that science subjects are complicated, but rather become fun because it is based on mobile learning to learn and play (Rachmat Rizaldi et al., 2022). Students are expected to be able to use an Android-based e-module because of the simplicity of the SAC's criteria (Syahputra & Prismana, 2021). Khaerani, K., M, U., & Nurmayanti, N. (2023). Development of Science E-modules on Solar System Materials Based on Android for Junior High School Students. Indonesian Journal of Instructional Media and Model, 5(1), 58-68. doi:https://doi.org/10.32585/ijimm.v5i1.4169 60 METHODS This research uses nd development (R&D) to developto develop The R&D model to be used is 4-D (Define, Design, Develop, Disseminate). It is predicted that this research will lead to the development of a straightforward, dependable, and practical android-based e-module for students to students to use as a t. The subjects of this study were material expert validators and media experts, as well as 23 students of class VII A and the seventh-grade science teacher. The research was conducted at SMPN 1 Watang Pulu, located on Jl. Andi Pakkanna No.5 Uluale Village, Watang Pulu District, Sidrap Regency. Distribution of validation tools in the form of questionnaires to media expert validators and material experts is the method used to collect data and respondents consisting of seventh-grade science teachers and seventh-grade students A. Quantitative data analysis has been used Quantitative data analysis has been used to examine the validity and applicability of android-based e-modules. To calculate the percentage of validity and practicality of e-modules, the following formula is used: Description: ∑x : Value of all respondents' answers, ∑x1: Value of all maximum answers (Sugiyono, 2015). When the percentage score ranges from 85.01% to 100.00%, results of the validity of e- modules will be deemed to be very valid or suitable for usage without further review; 50% to 70% have lower validity or can be used but require significant adjustments; 01.00%-50.00% is invalid or should not be used, whereas 70.01%-85.00% indicates that it is still valid but could use some small modifications (Akbar, 2013). The percentage score is 85.01%-100.00%, indicating extremely practical outcomes; 70.01%- 85.00%, somewhat practical results; 50.01%-70.00%, less practical results; and 01.00%-50.00%, not practical results. (Akbar, 2013). RESULT AND DISCUSSION A. Define Stage The defining stage is carried out by identifying problems and needs, so researchers found that: (1) the use of learning media that is less varied and constrained by the lack of school facilities that support learning results in students tending to be passive in the process of instructing and learning, (2) there is a change in students' learning styles after the covid-19 pandemic, namely students prefer to use digital devices, especially smartphones, (3) teachers need learning media that can compensate for students' tendency to smartphone activities as a solution due to reduced student enthusiasm for learning. Researchers found the necessity to deliver learning media packed into e-modules as autonomous learning tools for students, notably at SMPN 1 Watang Pulu, after identifying issues through observations of teachers and students. B. Design Stage Creating the material is the initial step required during the design phase. The material analysis refers to the SMP / MTs grade VII semester 2 Natural Science student book published by the Center for Curriculum and Bookkeeping, Balitbang, Ministry of Education and Culture in Khaerani, K., M, U., & Nurmayanti, N.
