“…This topic focuses on how physics learning or "course" can be delivered through real [125,[322][323][324][325][326] or virtual "laboratory" [327][328][329][330][331] in conducting the physics experiment (refers to "activity" and "practicum"). Several papers also have developed their own physical measurement "tool" and data acquisition using microcontrollers, trackers, or smartphones [124,[332][333][334][335][336][337] that could be employed to enhance students' experience within physics laboratories. Eventually, through this channel, PER studies also consider addressing their learning transformation to improve "understanding" of physics [338,339].…”

Abundant physics education research (PER) literature has been disseminated through academic publications. Over the years, the growing body of literature challenges Indonesian PER scholars to understand how the research community has progressed and possible future work that should be encouraged. Nevertheless, the previous traditional method of thematic analysis possesses limitations when the amount of PER literature exponentially increases. In order to deal with this plethora of publications, one of the machine learning (ML) algorithms from natural language processing (NLP) studies was employed in this paper to automate a thematic analysis of Indonesian PER literature that still needs to be explored within the community. One of the well-known NLP algorithms, latent Dirichlet allocation (LDA), was used in this study to extract Indonesian PER topics and their evolution between 2014 and 2021. A total of 852 papers (~4 to 8 pages each) were collectively downloaded from five international conference proceedings organized, peer reviewed, and published by Indonesian PER researchers. Before their topics were modeled through the LDA algorithm, our data corpus was preprocessed through several common procedures of established NLP studies. The findings revealed that LDA had thematically quantified Indonesian PER topics and described their distinct development over a certain period. The identified topics from this study recommended that the Indonesian PER community establish robust development in eight distinct topics to the present. Here, we commenced with an initial interest focusing on research on physics laboratories and followed the research-based instruction in late 2015. For the past few years, the Indonesian PER scholars have mostly studied 21st century skills which have given way to a focus on developing relevant educational technologies and promoting the interdisciplinary aspects of physics education. We suggest an open room for Indonesian PER scholars to address the qualitative aspects of physics teaching and learning that is still scant within the literature.

“…where: m is the average mass of an "air molecule" 1 (kg); N is the number of air "molecules" present in volume V (expressed in m 3 ). By replacing (12) in (10), using the ideal gas law (pV = N kT ) and the definition of molar mass (M = N 0 m), where N 0 is the Avogadro constant, one gets:…”

“…The use of technological resources in physics teaching and other disciplines occupies an ever-increasing important space in education, especially in laboratory practices. Their use started about 30 years ago with the introduction of computers in laboratory educational practices [1,2] and, more recently, with the popularization of electronic platforms such as Arduino [3][4][5][6], programmable logic devices [7], and microcontrollers [8][9][10]. Currently, familiarity and access to smartphones are the main contributing factors for their educational use in physics laboratories, mainly due to the possibility of installing applications (many free) that allow to instrumentalize the device and render it useful for teaching, as can be verified in many physics topics [11][12][13][14][15][16].…”

This work presents a didactic proposal to study atmospheric pressure. The introduction of technological resources in physics teaching is ever-increasing today. In this context, access to smartphones proves an accessible tool due to their massification and the possible uses of their built-in sensors. Therefore, we choose to use a smartphone as a barometer to measure the atmospheric pressure. We suggest experiments to measure atmospheric pressure as a function of height and time that can be easily reproduced by students in environments outside laboratories. The experimental results are compared with those provided by a meteorological station of the Company of Environmental Sanitation Technology of the State of São Paulo. Determining the atmospheric pressure variation as a function of height also allowed us to estimate the Boltzmann constant, thus establishing an experiment that can be introductory in statistical physics. Other than stimulating the practice and understanding of graphical analyses of experimental results, the proposed experiments serve as a deeper understanding of the atmospheric pressure phenomenon than that usually found in textbooks, proving to be a robust and suitable tool for physics teaching at an undergraduate level.

“…This research will design and modify weapon control from a manual to a camera-based controller system [5][6] [7][8] [9]. This research will use the Atmega 8 as a microcontroller [10] [11] [12][13] [14]. The ATmega controller functions as an interface for transferring data from the camera (optronic) to the servo motor.…”

⎯The development of technological science towards the defense of a country is growing rapidly. The country needs increasingly advanced defense technology but is constrained by an increasingly large budget due to dependence on producing countries. The state provides opportunities for technocrats to carry out research that can later create a defense technology that is inexpensive and does not burden the state budget. The artificial S60 57mm cannon is one of the cannons that functions as an air attack deterrent. The operating system of this weapon is still manual. This research will design and prototype an automatic Weapon Control System on the S60 57mm gun. In this development using the Atmega 8 microcontroller is the controller and interface for transferring data from the camera (Optronic) to the servo motor. The result of the camera position (optronics) will be followed in real-time by the gun barrel. In designing a target tracking control system automatically using the proportional control method. The results of testing the ability of the servo motor as a camera driver to follow targets or moving objects with a maximum angular speed of 15.5 degrees/second at a speed of 0.3 seconds, the average frame rate of the camera are 60 fps. c. Based on testing the servo motor using the Atmega8 microcontroller support, the reading of the angle direction of the servo motor is displayed in the Delphi software. Based on the test results, there is a difference between mathematical calculations and measurements using an arc ruler. With mathematical calculations, there is a difference with a value of 1.06 degrees per 1 degree.
