Utilization of a mobile device with the Android operating system that is used as a supporting medium and supplement in improving learning outcomes combined with demonstration and discovery learning or demon-disco learning methods is needed to help students improve learning outcomes in vocational competence subjects in hydroponic crop cultivation in vocational high schools Kristen Terang Bangsa, because the use of android-based applications can provide new experiences regarding the use of information and communication technology, as well as provide opportunities for students to be able to learn more independently.
The concept chosen as a learning media is to explain the material about understanding, introduction of parts, types, and quiz containing questions about hydroponic plant cultivation. This research uses the Research and Development (RnD) product development method, using 6 out of 10 stages research that is the potential and problems, data collection, product design, design validation, design improvement, product trials.
The results of this study are to produce learning media in the form of Android-based applications. The validity value of media experts is 2.6 which is declared feasible, while the validity value of material experts is 3.6 which is declared feasible, and is able to increase the average value in the subject of vocational competence in hydroponic cultivation in Christian Terang Bangsa Vocational Schools which initially 67 (with 13 students who had not yet reached KKM) to 80 (with 4 students who had not yet reached KKM).

Archiving in University that have not been well organized will cause a problems, the documents need for structuring and archives properly in the systems for the good standard a universities. The most importance of ease in finding the required archives is an important reason why it is necessary to develop an archive search system that can facilitate and improve the process of searching the archived document. Apllying cosine similarity algorithm in Information Systems is a solution for University to organizing archived documents, results from this reserach is the systems can show the relavant document from database list with precision 88.8% and recall 76.1%   from all the data in database.
