Abstract

The prototype resonant frequency is designed to work at 150 MHz. The signal source prototype is the signal that comes from handy talky (HT). There are two subsystems, which are Matching Impedance and Voltage Multiplier. The resonant frequency of the matching impedance subsystem at 143 MHz from 0.053 mH inductor and 0.0233 pF capacitor. The output of the matching impedance subsystem is then amplified by the multiplier voltage subsystem using parallel PH4148 diodes with the 6-stage multiplier. Load prototype is a CR-151 LED that works at 12 volts 1 watt. When the HT battery has a voltage of 7.3 volts, the prototype can turn on the lamp with the distance between the TX antenna and the antenna on the prototype less than 36 cm. The maximum voltage on the load is 6.8 volts with a length of 5 cm between the antenna and the lamp 774 lumen.

Abstract

Artikel ini mengeksplorasi hubungan antara filsafat pendidikan dan pembuktian matematika, menyoroti bagaimana pendekatan filosofis dalam pendidikan dapat memperdalam pemahaman mahasiswa terhadap konsep matematika. Pembuktian matematika sering kali dianggap sebagai proses teknis semata, tetapi memiliki dimensi filsafat yang kaya, yang relevan dalam konteks pendidikan. Penelitian ini mengidentifikasi beberapa teori filsafat pendidikan, seperti rasionalisme, konstruktivisme, dan realisme, dan mengevaluasi bagaimana penerapan teori-teori ini dapat membantu dalam pembelajaran pembuktian matematika. Penelitian ini menunjukkan bahwa pendekatan filsafat dalam pembuktian matematika tidak hanya dapat meningkatkan keterampilan logis mahasiswa tetapi juga memupuk pemahaman mendalam yang memungkinkan mahasiswa mengapresiasi matematika sebagai ilmu pengetahuan yang sistematis dan koheren

Abstract

This study aimed to evaluate the perceived usefulness of a teaching robot, Mi-Robot, in delivering linguistic and kinesthetic stimulation for children with special needs, based on teacher feedback. The study employed a mixed-methods design and involved 20 special education teachers from five inclusive schools in Bandung, West Java, Indonesia. Teachers participated in a 32-hour training program focused on integrating Mi-Robot into classroom activities. Data were collected using the Mi-Robot Acceptance Scale and an open-ended evaluation form. Quantitative data were analyzed using descriptive statistics, while qualitative responses were examined through thematic content analysis. Teachers reported high acceptance levels, with mean scores above 4.0 across all four TAM dimensions. Qualitative findings revealing that Mi-Robot was seen as curriculum-compatible, engaging, and cost-effective. Features such as gamification, visual appeal, and customizable challenges were noted to enhance student motivation and facilitate individualized learning. Participants expressed a strong intention to integrate Mi-Robot into their future teaching practices. Mi-Robot is perceived as a promising educational tool for supporting the development of linguistic and kinesthetic intelligence in children with special needs. Its usability, adaptability, and alignment with inclusive education goals make it suitable for classroom and distance learning contexts.

Abstract

This article explores the idea of improving the quality of education in the modern era by referring to Jacob Bronowski's thoughts in chapter II: The Harvest of the Seasons contained in the book The Ascent of Man. From the study of this chapter, the researcher found an interesting idea that deserves to be studied more deeply, namely about human development through discovery, creativity, and intellectual ability in The Harvest of The Seasons. This study provides a relevant perspective in the current educational context. As a conclusion from the results of the literature study supported by field studies, Bronowski's approach to human intellectual development at that time can be applied in the modern education system to face the challenges of the digital era and globalization. This study highlights three main perspective of Bronowski, namely: (1) Individual skills of learners grow and develop through an effective and efficient learning process; (2) Improving the learning process and adapting technology that continues to develop; and (3) The quality of education that can improve social welfare. These three points of thought can be used as the basis for the modern pedagogy paradigm, namely for the renewal of the curriculum and teaching methods that are more adaptive and relevant to the needs of the times. The results of this research are expected to contribute to developing an educational model that can improve the intellectual quality of students and prepare them to play an active role in the knowledge society.
