<![CDATA[The purpose of this study is to develop the Melonit applications an Android-based learning media on electrolyte and non-electrolyte solutions, and disclose the level of validity of the developed product regarding the validity of the content, construct and media. This type of research is Educational Design Research applying the Plomp development model, which consists of three stages, namely preliminary research, prototyping stage and assessment stage. The research instruments used were in the form of content validity questionnaires, constructs and media and one to one evaluation interview sheets. The results of processing the content and construct validity data were obtained at 0,89 with a valid category. Meanwhile, the validity of the media was obtained at 0,94 with a valid category. Research on android-based learning media applications that have been developed is valid, so that further research can be carried out on the practicality and effectiveness of the applications that have been developed.]]>
