This research aims to design and develop a media lab in the form of Augmented Reality applications that are used in basic physics lab module. AR applications work with a tracking system and the reconstruction of the 2D marker contained in the experimental module to display 3D video animation. The method used in this research is the development of software includes the stages of collecting and analyzing the needs, do the design and manufacturing applications, validation and testing by the user, and revision. Results of the assessment by the AR application validator media and materials are respectively 80% and 85% in the predicate is valid and may be used after minor revisions. The results of trials by students as the user indicates that the 2D marker on lab module was initially less obvious and less sensitive at the time of scanning. However, after the revision of the 2D marker on lab module, 2D AR marker was sufficiently clear and sensitive at the time of scanning so that AR can help the general practical implementation and the AR content to support the practical implementation. The results showed that the development of AR applications had been successfully carried out and the AR application can function well with the scan time 1-1.5 second at a distance of 10-20 cm and successfully used in the experimental module at an angle of <900, with the result that, AR applications in basic physics practicum module as the media are supporting practicum implementation

Essential concepts were important aspects in physics education, especially in the study of learning development, student evaluation, and curriculum planning. Several types of concept analysis models are commonly applied in the context of physics, i.e. sematic network techniques, concept formation (concept analysis), concept maps, and representing substantive structure. The stages of essential concept development were concept analysis, concept map and essential concept. The research method used development research. The stages of development research included (1) the preliminary study phase, (2) the development study phase, (3) the evaluation phase. The main results of this study were essential concepts on the topic of Kinematics.

Some people argue that museums are the building for saving antiquities. However, based on Government Regulation No. 6/ 2015, it is noteworthy that museums have other vital functions to educate and entertain people. For education purposes, museums can provide information and communication about their collection to visitors. One of the museums in Yogyakarta, which has communicated and informed the collections properly, is Museum Sandi. The museum is amazingly famous nowadays because of the number of visitors that constantly increases in each month. This is because the museum is located in a strategic place and that it is free of charge. However, the museum only has a few number of educators that do not suffice the number of visitors. It causes many difficulties to transfer the information about the collection optimally to the visitors. On this account, visitors are not able to get the whole knowledge provided by the museum's collections. It is possible to resolve this problem by an innovated application based on augmented reality. This application is developed using ADDIE model, which is expected to solve the problem in delivering the information and knowledge about the museum independently to the visitors. Thus, it is expected that visitors can grasp more insight about the museum's collections.
