One of chemistry is the chemical element that is represented by the symbol on the periodic table. The low level of activity, interest, and the result of chemistry learning in school is caused by the students generally having difficulty in solving problems related to chemical reactions. In addition, most of the chemical concepts are abstract so it is difficult to imagine the structure of molecules clearly. Augmented Reality can integrate digital elements with the real world in real time and follow the circumstances surrounding environment. Augmented Reality can provide a new more interactive concept in the learning process because users can directly interact naturally. By using Augmented Reality, the atoms in the periodic table will be scanned using a camera from an Android-based smartphone that has installed this app. The scan results are then compared with existing data and will show the molecular structure in three-dimensional form. Users can also observe reactions between atoms by combining multiple markers simultaneously. Augmented Reality application is built using the concept of user-centered design and Unity with personal license as development tools. By using this app, studying chemical reactions no longer requires a variety of chemicals that could be harmful to users.

Abstract The current periodic table does not necessarily have a clear position for transition elements. Therefore, the purpose of this paper is to use the basic principle discovered by Mendeleev as it is and to create a periodic ta ble with consistency for transition elements. By setting some hypotheses, it was found that transition elements also have regular periodicity, so we succeeded in clarifying the energy level of electrons in each orbit. In addition, by utilizing its periodic ity, the electron configuration for each orbit was predicted for unknown elements. In this paper, we did not take the conventional idea of electron orbitals, that is, the idea of forming a hybrid orbital, but assumed a new orbital.Since the state in which electrons fit in orbits and stabilize is defined as an octet, this idea was used as the basic principle in this paper, but the hypothesis that "there are only three orbits in each shell" was established and verified.The calculatio n of the energy level of the electrons on the orbit became extremely easy, and the order of each orbit could be clarified. It was also found that the three dimensional structure of the molecule may be visualizedby paying attention to the valence electrons of the outermost shell of the element and the octet of the stability condition. Therefore, in this paper, by slightly expanding the structural formula of Kekulé, it became possible to easily determine whether or not the molecule synthesized by the became possible to easily determine whether or not the molecule synthesized by the bond bebond between elements is stable.tween elements is stable. In addition, it has become possible to predict the three In addition, it has become possible to predict the three--dimensional structure of the dimensional structure of the molecule as well.molecule as well. Furthermore, not only will it be easier for students studying chemistry to understand Furthermore, not only will it be easier for students studying chemistry to understand complex chemical reactions, but it will complex chemical reactions, but it will also be useful for researchers in the development also be useful for researchers in the development and research of new drugs.and research of new drugs.

21st-century learning presents chemistry teachers with new challenges in teaching abstract chemistry concepts with various technologies that continue to develop. One of the media that can visualize abstract chemical concepts is Augmented Reality (AR). AR media developed in chemistry learning needs to be valid so that it can be used properly. Therefore, this study aims to examine the validity of the Android-based AR media developed. Four education practitioners carried out the validation as experts, and 13 students participated as respondents. The instrument used is a questionnaire with a Likert scale. The data obtained were analyzed quantitatively with the Rasch model using the facet software. The results of the analysis show that the Exact Agreements are 41.10%, and the Expected Agreements are 42.20%. The most challenging aspect to achieve is media design, while profit is the most easily agreed-upon aspect. Based on this assessment, in the development of augmented reality media, it is necessary to pay attention to display aspects and 3D objects suitable for viewing a material so that it is easier for users to understand the material.

Traditional electronic commerce (e-commerce) is facing a bottleneck because it cannot provide enough direct information about products to online consumers. The technology presented in this paper shows how Augmented Reality (AR) can be used to overcome the bottleneck and enhance e-commerce systems. The study also considers some key implementation issues. An AR e-commerce assistant system was developed, as an Internet plugin, which can be used on different kinds of computers and handheld devices when using the User-Centered Design method. Finally, a usability experiment was designed and a pilot test was also conducted, to compare the AR e-commerce assistant with traditional e-commerce and Virtual Reality (VR) e-commerce systems, and to verify that the AR e-commerce approach can be used to provide more direct information to online consumers. Results show that an AR e-commerce e-commerce system can provide more direct information about products than traditional or VR e-commerce systems.
