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.

Large organisations have many different interests, so there is often a lack of understanding of tasks and missions. This study identified several issues, including the impact of current elder performance in GPP Sukadono Helvetia, the condition of elder support that does not meet performance standards, the influence of management on performance, and the impact of elder workload on performance became the main focus of this study. This research is descriptive-inferential, where there are functional relationships. If leadership (X) is systematically related to employee performance (Y), then future phenomena are likely to be predicted and the results may propose new or additional hypotheses that can be tested. This study wants to reveal that there is a significant contribution between leadership effectiveness (X) and employee performance (Y), to the empirical contribution of 27.3%. This shows that leadership plays an important role in overcoming all challenges in the organisation. Elder leadership plays an important role of 27.3% in the performance of GPP Sukadono Helvetia. Then, this study also found that the role of management in this area has not been optimal, resulting in ineffectiveness in achieving the desired performance, especially in promoting learning and improving congregational performance. This study suggests that the role of management in the future should be more aligned with the management and effectiveness of GPP Sukadono Helvetia. This will ensure that the work of GPP Sukadono Helvetia elders is not only focussed on programme activities but also that the programme contributes to the overall success of the organisation.
