Sistem Pengaman Berbasis Microcontroler Internet Of Things (IoT) Sebagai Pengaman Rumah Interaktif

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.

The success of the indicators of this research were seen from the feasibility of the developed textbooks. Physics history textbook based on higher order thinking skills was categorized as good and suitable for use, in terms of content, presentation, and language feasibility. Meanwhile, in terms of textbook effectiveness, it was measured by the impact of increasing students' higher order thinking skills as seen from the increase in N-gain. The student's high-order thinking skills had increased with N gain 0.4 (moderate category). This shows that the textbooks that have been developed are feasible and effective in terms of the ability to increase higher-order thinking skills (HOTS).

Validitas Perangkat Pembelajaran Fisika Dengan Model Post Organizer Berbantuan Video

The purpose of this study is to determine the validity of the physics learning devices with post organizer models assisted by videos. The research design used research and development (R & D) design with 4D model (define, design, develop, & disseminate). Learning tools developed are sylabus, lesson plan, learner worksheets, understanding of concept, and learning video. This paper only focused on the process of testing the validation of the contents and constructs of the learning tool. This study is restricted to limited testing by taking the results of validation from the validator and questionnaire of response from students. Validation results using CVR and CVI indicate learning tools in the very feasible categories and reliable. The results of limited trial show that students’ response of 99.94% and 98.31% with very good categories. So it can be concluded that tools with post organizer models assisted by learning videos are feasible and can be used in physics learning.

Identifikasi Kemampuan Berpikir Logis Mahasiswa Calon Guru Fisika Menggunakan Instrument TOLT

This study aimed to identify the type of reasoning and the level of prospective physics teacher students’ logical thinking ability. This type of research was a field study with a quantitative descriptive method. The test was the technique used in collecting data of this study. The instrument used in this study was the standard test like Test of Logical Thinking (TOLT). This test consists of 10 questions that measured five types of reasoning, namely proportional reasoning, variable control, probabilistic reasoning, correlation reasoning, and combination reasoning. The level of logical thinking ability was distinguished into concrete, transitional, and formal thinking operational. The sample of this study was students of physics teacher candidates at the first-year level, totaling 30 students. All of data was analyzed by quantitative descriptive. In general, students tend to the type of proportional reasoning and controlling variables and less on probabilistic reasoning. Based on the level of logical thinking ability, the results showed that the percentage of 30 students who were in the concrete, transitional, and formal categories, respectively, were 30%, 30%, and 60%. This data becomes the basis for consideration in the development of learning models and learning assessments used in lectures, especially in Department of Physics Education in one of the University in Makassar city, so that they are able to contribute to the development of students' level of logical thinking skills as a provision for the next life.

The feasibility test obtained a proportion of 92.58% in the eligible criteria.

Analisa Kognitif Model Blended Learning Dengan Pendekatan Kalkulus Dasar

This research was motivated by the low learning outcomes of students in basic physics courses. This is due to the learning of basic physics which requires mathematical analysis in interpreting and analyzing the variables of physical quantities. The purpose of this study was to see the increase in learning outcomes as a result of the application of the blended learning model with the basic calculus approach. This approach is used because basic calculus can analyze basic physical substances through differential and integral languages. The sample of this research was students majoring in mining ISTP Medan. The research method used was a Quasi-experimental one group design. To see the learning outcomes, a learning outcome test is used and a gain test is used to improve learning outcomes. The results showed that the gain test at the first meeting was 0.6, the second meeting was 0.6 and the third meeting was 0.7 with the high category. From research result there is an increase in the gain for each meeting, it is concluded that there is an increase in student learning outcomes as a result of the blended learning model with the basic calculus approach.

This study aims to identify students' misconceptions on Newton's Law using the Five-Tier Newton's Laws Test (5TNLT) instrument. The process of identifying misconceptions is carried out as one of the first steps to overcome student misconceptions. The method used in this study uses the 4D model (Defining, Designing, Developing, and Disseminating). Participants involved in this study consisted of 327 students (198 female and 129 male), who came from 2 public high schools and 1 private high school in Bandung. Based on the research, it was found that the 5TNLT instrument developed by the researcher could be used to identify misconceptions and causes of students' misconceptions on Newton's Law. All items on the 5TNLT instrument are valid and reliable enough to measure student misconceptions. The highest percentage of misconception categories is shown in the MC-PT (Misconception from personal thoughts) category, which is 50.21%, while the smallest percentage is shown in the MC-I (Misconception from the internet) category, which is 14.82%.
