Chemistry is one of the fields of science that is still difficult for students to understand. This is due to the abstract and microscopic nature of chemical materials. One of the topics in chemistry is chemical bonding. Chemical bonding material that studies the structure of atoms and molecules, is difficult for students to understand because of its microscopic nature, which makes it difficult for students to imagine the form of chemical bonds. To overcome this, it takes the role of learning media that can provide an overview of the form of chemical bonds in students. Augmented Reality (AR) technology can combine three-dimensional virtual world objects into a real three-dimensional environment. So, Augmented Reality (AR) based learning media were developed for chemical bonding materials. This research is a development research, with stages starting from pre-production, production to distribution. Data collection technique uses the qualification of the percentage score feasibility test results. Based on the validity test, it states that the teaching materials of Augmented Reality (AR) Chemical Bonds in terms of material are declared very valid, do not need revision, in terms of media they are declared very valid, do not need revision and from the feasibility test students state that this teaching material is very valid, no need for revision.

Abstract The use of batteries in electronic tools can cause environmental pollution. This problem can be solved by using natural ingredients that can replace conventional batteries as a source of electrical voltage. This topic is suitable for students to learn in class by reviewing aspects in the fields of Science, Technology, Engineering, and Mathematics (STEM). For STEM’s activities, we used Yuenyong’s Science-Technology-Society (STS) approach, and for data analysis, we used mixed methods, where quantitative methods to classify the data and qualitative methods to analyze student perspective. In this study, students are given lemons, limes, potatoes, apples, tomatoes, and cucumbers as fruit cells. Then all fruits are connected by coins, nails, cables, multimeters, and LED lamps. The results obtained by students is conventional batteries cells can be replaced by fruit cells. All fruit cells that we used like cucumber, apples, tomatoes, limes, lemons, and potatoes are capable of producing electrical voltage. Cucumbers and tomatoes produce the higher electrical voltage (5,0 volts & 3.0 volts) but have a dim LED’s light, while potatoes, lemons, limes, and apples produce the lower electrical voltage (1.35 volts, 2.0 volts, 2.2 volts, and 3.4 volts) but have bright LED lights.
