“…The pressure measurement control device mainly monitors the pressure of the support. Each device is equipped with four sensors, which can connect the hydraulic cavity of the support column, balance jack, and probe jack [21][22][23]. After the receipt of the instruction of the communication measurement and control system, the pressure of the four channels was measured, and then, the four sound pressure signals were transmitted to the measurement and control center through the communication measurement and control system and then transmitted to the ground through the communication measurement and control center.…”

To solve the trouble of cervical vertebra disease caused by long working hours, this work is aimed at designing an active monitor stand to achieve the best dynamic trajectory planning. The stand operation system consists of image input, face positioning, and robotic arm. According to the user’s face positioning, the inverse kinematics method is used to calculate the steering angle in each direction, and the height and angle are adjusted to make the corresponding selection for the user’s display position on the screen. The C++ is used to program the algorithm, and its core is to control the rotation speed of the motor to ensure that the display screen will not cause any interference to the normal work of the user when the bracket moves. In the inverse operation, the Piper method is used to solve the inverse kinematics issues. After testing, the sliding wedge stroke of the developed active display stand is 0.6 mm, and the height position difference at the reference zero point after the display stand is measured with a digital altimeter is 7.12 mm, which indicates that the stand shows a large deformation after being mounted. This work is of important reference value for realizing the movement of active display stand.

Salah satu permasalahan dalam pembelajaran IPA adalah pemahaman konsep siswa yang belum maksimal sehingga harus diketahui tingkatannya agar dapat diatasi. Pemahaman konsep dapat diukur dengan dengan tes pemahaman konsep. Salah satunya berupa pilihan ganda empat tingkat (4TMC). Penelitian dilakukan untuk mengetahui efektivitas instrumen tes 4TMC tema listrik sahabat kita yang akan digunakan dalam mengukur tingkat pemahaman konsep siswa. Penelitian dilakukan pada semester ganjil TA 2022/2023 pada tiga SMP Negeri di Kota Tangerang. Metode penelitian mix method dengan desain sequential explanatory. Instrumen yang dipergunakan adalah 4TMC sebanyak 42 butir soal dengan 12 butir soal dinyatakan valid, lembar validasi instrumen tes dan instrumen nontes berupa wawancara. Efektivitas instrumen tes 4TMC tema listrik sahabat kita dalam mengukur pemahaman konsep siswa telah diuji kelayakan berdasarkan validasi ahli meliputi aspek isi sebesar 90% (sangat valid), aspek penyajian sebesar 89% (sangat valid), aspek kebahasaan 92% (sangat valid). Hasil tes pemahaman konsep siswa tema listrik sahabat kita mendapatkan persentase pemahaman konsep siswa yaitu paham konsep sebesar 16% (sangat rendah), tidak paham konsep sebesar 58% (cukup) dan miskonsepsi sebesar 26% (rendah). Oleh karena itu, perlu tindak lanjut seperti pengembangan strategi pembelajaran hingga media pembelajaran untuk mengatasi dan mencegah rendahnya pemahaman.

“…Therefore, it is necessary to do a misconception detection test first to determine whether a teacher has a misconception. Previous research discussing kinematics misconceptions in students has been widely carried out [12][13][14][15] and also on prospective teachers [16,17] but rarely has research been conducted on active teachers [18]. This research was conducted to determine the profile of physics teacher's understanding of concepts on kinematics.…”

The role of a physics teacher in learning is to facilitate student activities to construct correct conceptual understanding as that of a scientist. As the primary source of knowledge for students, a physics teacher is required to have the right concept, but this demand is not necessarily fully fulfilled. This study aims to determine the profile of physics teachers’ understanding of concepts on kinematics material detected by a four-tier misconception test. Participants in this study were 20 high school physics teachers in Surabaya. Based on the results of data analysis, it was found that the dominant misconceptions included: (1) Two objects that make the same displacement at the same time interval will have the same velocity, regardless of the type of movement of the two objects (2) Objects that move vertically straight up or down will always have the acceleration of motion equal to the acceleration of gravity which is directed downwards. (3) As long as the object’s position is at positive coordinates, it means the object is moving in the forward direction. (4) The graph of velocity against time, which has a positive gradient, means that the object always moves forward (5) In parabolic motion, the length of time an object is in the air only depends on the length of its path, the longest path will require the longest time. (6) In parabolic motion, the final speed of an object when it lands on the ground depends not only on its initial speed but also on its elevation angle. The findings of several misconceptions above show that even a physics teacher cannot escape misconceptions. Therefore, it is crucial for a teacher to be able to remedy the misconceptions he suffers so that these misconceptions are not transmitted to the students he teaches. This finding is the first step for researchers to detect misconceptions, followed by the application of certain learning methods to remedy misconceptions in future research.
