Abstract

The low students' mathematical critical thinking ability in one of the high schools in Bandung City is a problem that requires teachers to develop and implement innovative learning approaches. Various previous studies have shown that creative learning and encouraging active involvement of students can improve critical thinking skills. This study uses a mixed method with an embedded design type, especially an embedded experimental design model, and adopts a pretest-posttest control group design. The purpose of this study is to examine the effectiveness of the Desmos-assisted Creative Problem Solving (CPS) learning model in improving students' mathematical critical thinking skills. The population of this study is high school students in the city of Bandung, with a purposive sampling technique to select two classes as a sample. The instruments used included mathematical critical thinking ability tests, observation sheets, and interview guidelines. The results of the data analysis showed that the improvement in mathematical critical thinking skills of students who obtained Desmos-assisted CPS learning was higher compared to students in the control class. Therefore, the Desmos-assisted CPS learning model is effectively used in an effort to improve students' mathematical critical thinking skills, especially in social studies classes students, and can be used as an alternative approach to learning mathematics in schools. This research is expected to contribute to the development of mathematics education, especially in the integration of technology with innovative learning models to encourage students' critical thinking skills.

Abstract

Electrical impedance tomography (EIT) supports recent advancements in gastric monitoring for telehealth applications. The challenge in providing low-cost EIT is ensuring a stable current injection over diverse tissue conductivities within the abdominal cavity. Three current source circuits based on Howland's current source are investigated to be applied in a low-cost portable bioimpedance analyzer (p-BIA). Those are: a) triple amplifier Howland current source (TAHCS), b) mirrored Howland current source (MHCS), and c) composite mirrored Howland current source (CMHCS). Evaluation has been conducted based on signal-to-noise ratio (SNR), broadness of the frequency range, and output impedance over frequency value and stability. Due to its high SNR value (82.56 to 102.1 dB), broad (500 Hz to 500 kHz) operating frequency, and consistent output impedance over operating frequency (10 to 25 kΩ), CMHCS is a good option in realizing p-BIA in gastric monitoring based EIT.

Abstract

This research examined how the anthropological approach to Islamic education is in building noble spirituality and overcoming problems of social conflict. The object of study is the student boarding school, Mahad Talhah bin Ubaidillah to be precise, Palu City, Central Sulawesi Province. This study uses a phenomenological approach, including a type of qualitative method. It collects data using observation interviews, documentation, and single data analysis (individual case analysis). The study's results found that the value of ukhuah Islamiyah was instilled to form students who always maintain unity and create harmonious relationships. Instilled noble moral values to shape students to become polite individuals, both in speech and in behaviour. In addition, it is customary to hold deliberations when facing problems, which is done to shape students into individuals who respect and respect the opinions of others, not feeling the most righteous themselves. As well as the habit of maintaining other people's privacy, this is to form students into individuals who do not like to interfere in private matters. Given that students live together in the dormitory. When these values are not instilled, they will disturb and damage the comfort of other students. This conclusion can become an idea for realizing good spirituality and can be a reference for overcoming social conflicts.

Abstract

There is a change in how teachers teach and students learn, which was initially done face-to-face at school, but now can be done online. The use of interactive learning media still needs to be improved due to the need for mastery of technology owned by teachers. Many teachers still need to understand practical learning applications for teachers and students. Students become less interested in participating in distance learning activities due to the limited use of various applications. So PKM activities were held as training workshops for making Edpuzzle-based teaching materials. The workshop was held for four days and involved 236 participants from various regions in Indonesia, such as Samarinda, Pekanbaru, and several areas in West Java. The activity method is divided into three steps: 1) preparation, 2) implementation, and 3) evaluation. Evaluation results based on questionnaire data show that 71% of teachers are assisted in monitoring student learning progress, and teachers can implement their work into learning.

Abstract

The increasing penetration of renewable energy sources in Indonesia, particularly photovoltaic (PV) systems, into electric power grids has led to a reduction in system inertia, potentially compromising frequency stability during disturbances. This paper proposes a virtual inertia control method for single-phase rooftop PV inverters to enhance frequency response in low-inertia microgrids. A single-phase synchronverter model based on the swing equation was developed and tested on the IEEE 13-bus system. Three scenarios were evaluated: a solar-only microgrid, a wind-integrated microgrid, and a microgrid combining renewable sources with a synchronous generator. Simulation results demonstrated that the proposed virtual inertia method improved frequency and voltage stability, closely mimicking the response of traditional synchronous generators. Within the first 10 s following a disturbance, the system failed to restore its frequency to the nominal value due to insufficient inertia in the inertial response time range. This indicates that the initial 10 s are a critical period for frequency recovery. The poorest frequency response was observed in scenario 1 (solar-only configuration), where system inertia was the lowest among the three scenarios, while the hybrid configuration with a synchronous generator (scenario 3) provided the most stable and robust frequency performance. The findings support the recommendation to implement policies requiring rooftop PV systems to incorporate virtual inertia functionalities, ensuring greater system resilience as renewable energy penetration increases.
