Abstract

Practicum is an activity that helps students to understand an abstract concept. One of the concepts in physics that requires practicum is the concept of electricity. Inductance is an electrical quantity studied in high and vocational high schools. This study aims to determine the inductor's inductance value using several methods and analyze the most suitable method for determining the inductor inductance value. The inductor used is a commercial inductor with a color band code with an inductance value of 2.7 mH and a tolerance of 10%. Inductor inductance measurements were carried out using a benchtop LCR meter, handheld LCR meter, series RLC method, and LC resonance method. Each measuring instrument requires a frequency setting: refer to the manual for benchtop and handheld LCR meters, the resonant frequency for the serial RLC method, and adjusting the AFG (arbitrary function generator) frequency. Hence, a clear oscillation pattern is visible on the oscilloscope. The results of this study indicate that measurements using benchtop LCR meters, handheld LCR meters, and LC resonance methods produce inductance values within the inductance tolerance limits.

Abstract

Indonesia is an agrarian country that produces fruits in abundant quantities and in various variations. Fruits contain diverse contents, one of which can be utilized as a dielectric capacitor. This research is conducted to provide senior high school students with an understanding of the influence of dielectrics from several fruits on capacitance. This experiment analyzed the maturity level of fruits and their effectiveness as dielectric capacitors for parallel plate capacitors. Due to the maturity level of fruits being composed of many variables, this study is focused on differences in water content, sugar concentration, and acidity level. Through laboratory experiments, researchers examined these factors in guava, papaya, pear, mango, and apple fruits. The capacitance value of parallel plates is measured using an LCR meter, and it is found that the capacitance of parallel plates with air dielectric increases significantly when infiltrated with fruit dielectric. Water content has a significant influence. The capacitance value is also high in fruits with high water content and vice versa. Meanwhile, the influence of sugar concentration is less significant in this study, only noticeable in papaya fruits. However, this is supported by the fruit's acidity level as seen from its pH value. Fruits with high pH values also have high capacitance. Experiments found that as fruits ripen, their water content, sugar concentration, and pH value tend to increase. This causes mature fruits to be more effective when used as dielectric capacitors.

Abstract

This study aims to improve the mathematical critical thinking skills and learning motivation of 5th grade students of UPT SDN Kutorejo 3 Tuban through the application of the Problem Based Learning (PBL) learning model with material comparing and sorting fractions. This study uses a Classroom Action Research (CAR) approach consisting of two cycles. The subject of the study was grade 5 students with a total of 29 students. The instruments used in this study include tests to assess mathematical critical thinking skills, learning motivation questionnaires, and observation sheets of the learning process. The results showed a significant increase in students' mathematical critical thinking skills and learning motivation after the application of the PBL model. In the first cycle, 69% of students achieved completeness in the critical thinking test, while 31% of students did not complete it. Based on the results of the questionnaire, 40% of students showed low motivation to learn. In the second cycle, the percentage of completeness increased to 75.8%, with 22 students achieving completeness. In addition, students' motivation to learn also increased, with 87.84% of students showing higher motivation compared to the first cycle. Thus, it can be concluded that the application of the PBL model is able to encourage the improvement of mathematical critical thinking skills and learning motivation of 5th grade students at UPT SDN Kutorejo 3 Tuban.

Abstract

This study aims to numerically analyze the distribution of axial and radial magnetic fields in a finite solenoid using MATLAB software. The simulation is based on classical magnetic field theory, particularly the Biot–Savart law, along with Pathak's analytical approach for modeling the radial field component. The primary focus is to understand the magnetic field behavior around a solenoid of finite length, which is commonly used in various electromagnetic applications. The simulation results reveal that the axial magnetic field remains relatively uniform within the central region of the solenoid but decreases significantly near its ends due to the fringe field effect. Meanwhile, the radial magnetic field outside the solenoid exhibits an exponential decay with increasing radial distance from the axis, consistent with the behavior of a magnetic dipole field. These findings offer preliminary validation of the theoretical models applied in the simulation while emphasizing the need for further experimental verification. This research is expected to contribute to the design, development, and optimization of experimental devices involving finite solenoids, particularly in applied physics and electromagnetic engineering contexts.

Abstract

In this study, the researchers focused on testing experimental media from Yeti Rusmiati to measure the dielectric constant of capacitors, with variations in thickness, surface area, material, and density. The experimental results show that the thicker the dielectric material, the smaller the capacitance value. This applies to all materials tested, namely mica, silicon, and duplex paper, with errors from largest to smallest being 24.97% duplex, 7.27% mica, and 0% silicon. Measuring the capacitance of parallel plate capacitors with variations in plate area from GRC gypsum, silicon rubber, and mica, it was found that the error from largest to smallest is mica 11.56%. In comparison, silicon rubber and GRC gypsum have an error of 0%. Measurement of capacitance by varying the dielectric material shows that the capacitance value of the capacitor is proportional to the dielectric constant of the material. Among all the 12 materials tested, the highest dielectric constant is banana leaves with a value of ? = 12.6 and the smallest flannel with a value of ? = 1.02. In contrast, the variation in density shows that the greater the density, the greater the dielectric constant, from the largest to the smallest, the variation in density of leaves steamed with fire, fresh leaves 1 x 24 hours, and dry leaves heated with the sun, respectively 67.51;22.96; 16.57. It can be concluded that Yeti Rusmiati's media can be used in measuring dielectric constant with variations in thickness, area, density, and dielectric material in learning capacitors.

Abstract

The handling of problematic students in schools has become an important issue in the world of education, especially when the policies taken cause controversy. One policy that has attracted a lot of public attention is sending troubled students to military barracks as a form of character building and discipline. This policy has sparked debate in the community because it involves approaches, educational values, and long-term impacts on the psychological development of students. This research also aims to analyze the implementation of the policy from various perspectives, including local government, school, parents, students and psychology education experts. The method used is qualitative with a case study approach. Data were collected through documentation studies and secondary interview analysis. The results showed that the policy of sending troubled students to military barracks reaped pros and cons, although it received support from several parties because it was considered to form discipline and character, many parties considered the militaristic approach was not in accordance with the principles of humanistic education and had the potential to cause psychological impacts and violations of human rights. This research concludes that in an effort to foster troubled students, the approach should pay attention to the balance between discipline and empathy, and prioritize pedagogical principles and the protection of children's rights. Therefore, a more participatory, evidence-based policy formulation is needed and involves the active role of all parties to create a fair and effective education system in dealing with deviant behavior in the school environment. Keywords: Education policy, Problem students, Military barracks, Multi-stakeholder perspective, West Java.
