Learning Media applications that use an Android-based material delivery system are expected to facilitate the delivery of material, where previously material was only found in books and the internet. Learning materials that only come from books reduce the reader's understanding because there are only text and pictures. This is what underlies the selection of the thesis title "Application of Android-Based Hydroponic Vegetable Growing Learning Media Application" in the hope that it can be a solution to help people who take part in the training understand material about growing vegetables by hydroponics.Hydroponics is an agricultural activity carried out by using water as a medium to replace soil. So, hydroponics can be interpreted as a work or management of water as a medium for plant growth without using soil media as a planting medium and taking the required mineral nutrients from a nutrient solution dissolved in water. The learning media application for growing hydroponic vegetables based on Android is limited to material on hydroponics, planting media and tools used in hydroponics, the steps needed for hydroponic farming, systems or techniques that exist in hydroponics.

The method or strategy in the learning process is something that is important to support the success of learning objectives. Some educational institutions still apply the classical learning model so that educators feel they are still in a comfortable condition in carrying out the learning process. Meanwhile, nowadays the demands of the curriculum and the development of science and technology greatly affect the learning process. Educators should use learning models that make students more creative, think critically, be active and be able to develop ideas in their own way. This of course can improve student learning outcomes. As for the results of this study, it can be concluded that the Active learning model applied at MTs Khoirotul Islamiyah, Pematangsintar City, is manifested in several components that influence each other, namely learning objectives, selection of learning methods and media that are appropriate to the content/subject matter as well as teachers and students. These components are designed so that in practice students are more active in learning. This strategy is applied to make it easy for students to know, understand, appreciate, and apply the material conveyed by the teacher in student life, so that the goals of studying economics can be realized. There are two supporting factors for the implementation of Active learning in Economics learning including; teacher professionalism, facilities and infrastructure. Meanwhile, there are two factors that hinder the realization of Active learning strategies in Economics learning, namely: the teacher's lack of preparation in planning learning scenarios and the lack of student motivation due to different backgrounds, such as the social environment, cultural environment, learning styles, economic conditions and level of intelligence.
