Analysis of Students' Scientific Argumentation Skills in the Toulmin's Argumentation Pattern (TAP)-Based Learning Model in Understanding Physics Concepts with the Library Research Method]The aims of this study was to describe the application of Toulmin's Argumentation Pattern (TAP) learning model in Physics. Observations focused on the impact of increasing students' conceptual understanding and argumentation skills in the field of physics. This research uses the library research method. The research was carried out by collecting journal data and scientific articles published online and indexed by the Google Scholar page, downloading, and then organizing the articles in the Mendeley application. In reviewing scientific journals, this research is carried out following the following steps: (1) Organize, which is to select the types of journals that are in line with the type of research; (2) Synthesize, namely reading and summarizing each journal into a coherent and structured research essence; and (3) Identify, namely drawing conclusions from each journal and making a summary evaluation of the entire journal. Based of the results from the study, was found that the application of Toulmin's Argument Pattern (TAP)-based learning can improve argumentation skills and understanding of concepts, especially in the field of physics. The results of a review of previous research by researchers can be concluded that learning based on Toulmin's Argumentation Pattern has advantages: it affects argumentation skills, increases the strengthening and acceleration of understanding concepts, builds better argumentation patterns, improves the quality of argumentation, and creates creative and innovative students in development. the material in the learning. As for the shortcomings of this argumentation learning model, there is the initial obligation of students to have a good literacy foundation.

The development of technology is currently happening very quickly and has become a part of human life. One technology that has become an important part of human life is the application technology of an interactive smart home security system (smart house). This can overcome various problems that often occur in home security which were previously only controlled by manual systems and were prone to theft crimes. The purpose of this research is to develop an Arduino-based interactive smart home technology that works automatically by relying on sensors and without a wireless remote-control device such as a remote control based on an Android application. The research method used by the research team is the development of a prototype which includes smart home technology, home security devices, and automation of smart home devices which are realized by two-dimensional and three-dimensional engineering methods for house models in the form of electronic circuits, as well as home electrical and security plans. The development of this technology provides significant benefits, including making it easier for users of the interactive smart house feature, so that its use becomes more practical and efficient as well as disability friendly and all ages. Indonesia needs to keep moving forward in terms of technological development and innovation, especially in terms of home security and the manufacture of smart homes by utilizing the Internet of Things (IoT) and applications on Android. Until later Indonesia can match up to the stage of surpassing the technological capabilities that have been applied in various developed countries and products can be patented into an Internet of Things (IoT) based security system.
