ABSTRACT The use of mobile devices with the Android operating system which are used as supporting media and supplements in improving learning outcomes combined with demonstration methods and discovery learning or demon-disco learning is needed to help students improve learning outcomes in hydroponic plant cultivation vocational competency subjects at SMK. 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 medium is to present material about understanding, introduction to parts, types, and quizzes containing questions about hydroponic cultivation of plants. This research uses the Research and Development (RnD) product development method, using 6 out of 10 research stages, namely potentials and problems, data collection, product design, design validation, design improvement, product testing. The result of this research is to produce learning media in the form of android-based applications. The validity value of the media expert is 2.6 which is declared feasible, while the validity value of the material expert is 3.6 which is declared feasible, and is able to increase the average value in the hydroponic plant cultivation vocational competency subject at the Terang Bangsa Christian Vocational School which Initially 67 (with 13 students who had not reached the KKM) to 80 (with 4 students who had not reached the KKM).

Fostering students’ creativity in learning is not effortless because the average learning activity is usually less challenging. Authentic problem-based learning is a learning model that is expected to foster students' creativity in education. This study aimed to examine expert and practitioner validation on authentic problem-based learning tasks prototype in promoting student creativity. The prototype product was displayed and simulated in virtual zoom and validated by 14 learning experts and 18 practitioners/teachers. The initial data were collected through self-evaluation using a questionnaire. The results showed that the use of real experiences as a learning stimulus could foster creative solutions, which are marked by the emergence of new, unusual ideas, imaginative ideas, new creations that have an impact on the development of student creativity.

In the implementation of the 2013 Curriculum, attitude competence is one of the main components of learning, but there are not many quality measurement attitude competency instruments. The purpose of this study was to obtain quality disciplinary attitude assessment instruments for class X students. This type of research is research and development using the Borg & Gall model. The stages of the activities carried out are the identification of potentials and problems; Gathering Information; Model Development; Model Validation; Model Revision; Model Trials; Model Revision; Wider Trial; and Final Model Revision. Based on the results of the research and discussion in this study, it can be concluded that there is no difference in the learning discipline of students between those who live with their parents and students who live in the dormitories. This is because students are adults and can be independent, and already have responsibilities even though they are not with their parents. The results of the calculation of the average score of learning discipline of class X students at MAN 3 in the 2016/2017 academic year Bantul is 96.2466 and is included in the high category.
