Abstract

This study uses the Taguchi method to optimize the quality factor (Q-factor) of microring resonators (MRRs) for sensor applications. The MRRs are compact optical components widely used in biosensors and environmental monitoring due to their sensitivity to refractive index changes. The Q-factor, a key performance metric for MRRs, is significantly influenced by structural parameters such as ring radius (R), gap (g), waveguide width (W), and waveguide height (h). We employed a finite difference time domain (FDTD) simulation to model light propagation within the MRR and compute the corresponding Q-factor to identify the optimal combination of these parameters. An L9 orthogonal array (OA) is used in the Taguchi method to analyze each factor's influence with three levels systematically. The optimization resulted in a Q-factor of 6208.44, significantly higher than the baseline value, indicating a substantial improvement. Compared to previous works, this research highlights the advantages of combining FDTD-based electromagnetic modeling with statistical optimization, offering a structured yet efficient approach to MRR design. The proposed method enhances Q-factor performance and provides scalability for practical applications in biomedical and environmental sensing. These findings underscore the utility of Taguchi-based design in advancing the field of photonic sensor optimization.

Abstract

This study aims to produce a product in the form of a physics teaching aid for secondary school on the topic of Archimedes’ principle. The developed teaching aid consists of an Arduino as the main controller, a mass sensor to detect changes in the mass of the submerged object, and a beaker attached to acrylic and supported by a stand. The device can automatically record mass changes of the load and the measuring beaker. The research method employed is R&D with a 4D model, consisting of four stages: Define, Design, Develop, and Dessimination. The variable used is the variation in the depth of the submerged object. The Arduino output is presented in the form of data and graphs using Microsoft Excel. The product has undergone material and media validation tests with average percentages of 90.67% and 100%, respectively. Based on the results, it can be concluded that the Archimedes’ principle teaching aid using Arduino is valid as a supporting medium for physics learning. The limitation of this study is the absence of the dessimination stage involving teachers and students. However, this study successfully produced a teaching aid that can be used to support the physics learning process.

Abstract

This article develops a vibration monitoring system on the machine using the RS-WZ3 sensor, which is based on MEMS (Micro-Electro-Mechanical Systems) technology. The RS-WZ3 sensor can measure vibrations on three axes (X, Y, and Z), as well as the surface temperature of the motor. The MAX485 module and the ESP32 microcontroller transform the vibration data from the sensor into a digital signal, subsequently displaying it on a web interface accessible remotely in real time. Sensor calibration is carried out by comparing the measurement results of the RS-WZ3 sensor with those of the GM63A vibration meter, which shows good accuracy with an average error of 2.01%. Testing of this system shows that the RS-WZ3 sensor is effective in measuring and monitoring machine vibrations in real time, enabling more efficient predictive maintenance and reducing maintenance costs.

Abstract

Electrodeposited nickel coating has excellent physical and mechanical properties, however it does not withstand to high temperature oxidation for long time. The addition of nitride phase within the nickel based coating improve the oxidation resistance through dense surface morphology improvement. A preliminary study was performed to investigate the high temperature oxidation behavior on the coating morphology after exposed at high temperature. The Ni-TiN/Si3N4 composite coatings deposited at electrodeposition temperature of 35 ℃, 40 ℃ and 50 ℃. The electrolyte consists of 0.17 M NiCl2.6H2O, 0.38 M Ni2SO4.6H2O, 6 g/L TiN, 0,6 g/L Si3N4, 40 g/L H3BO3, 0,6 g/L Sodium Dodecyl Sulfate (SDS).  High temperature oxidation process on the samples was performed by heating at temperature of 700 ℃ for 2 hours within air conditions. The morphology and composition samples were characterized by using SEM/EDS. In general, the result showed that the morphology of Ni-TiN/Si3N4 composite coatings became rough due to the oxidation process. Elements coating such as Ni, Ti, Si and N were disappeared after the oxidation process due to the outward diffusion process.

Abstract This community service program was designed to enhance the pedagogical and technological competencies of physics teachers in MGMP Fisika Jakarta by introducing them to sensor and microcontroller-based learning media. The training consisted of eight structured sessions, beginning with an introduction to microcontroller fundamentals and various types of sensors, including their working principles and real-world applications in physics education. Participants then engaged in hands-on training on operating microcontrollers and constructing measurement instruments, such as temperature and distance sensors, integrated into microcontroller systems. Teachers were also guided through the process of developing simple, sensor-based educational devices tailored to classroom use. To support effective implementation, the training included the creation of a practical guidebook and the production of demonstration videos that could be used in future instruction. Futhermore, participants learned how to build and utilize a Learning Management System (LMS) using Moodle to digitize and manage learning content. The training was delivered through a collaborative, workshop-based approach that encouraged active participation and creativity. As a result, teachers not only improved their technical skills but also gained the ability to integrate technology into physics instruction in innovative ways. The program demonstrated that equipping teachers with skills in sensor and microcontroller technology can significantly enrich STEM-based teaching and learning experiences.

Abstract

The Free Private School Pilot Program (RSSG) is an innovative policy by the Depok City Government to expand access to education for low-income families through partnerships with private schools. Initial findings show that the quality of RSSG schools in Depok City varies greatly. Of the 47 participating schools spread across 11 subdistricts, 20 schools are accredited A, 23 are accredited B, two are accredited C, and two are not yet accredited. The total number of students reaches 2,407. The variation in accreditation and infrastructure shows a gap in quality between schools, which is the basis for the implementation of mentoring. Therefore, it is necessary to strengthen school quality through RSSG mentoring collaboration. Jakarta State University is the institution entrusted with carrying out community service activities through mentoring teachers and school principals. These community service activities are carried out by lecturers and students of Jakarta State University (UNJ) as part of efforts to strengthen the quality and sustainability of the program. The community service activities focused on two main areas: (1) mentoring teachers in 47 RSSG schools through four cycles of thematic training on strengthening understanding of student characteristics, implementing deep learning, active learning models, and creating simple learning media; and (2) training school principals at Depok City Hall on the theme of “Strengthening School Branding and Culture,” which was attended by 47 school principals. The results of the activities showed an increase in teachers' knowledge and capacity in designing meaningful, contextual, and relevant learning for students' needs, as well as the growth of school principals' awareness in building a positive institutional identity and culture. This program not only improved the technical quality of learning but also strengthened the collaborative ecosystem that supports educational equity in Depok City.   Abstrak Program Rintisan Sekolah Swasta Gratis (RSSG) merupakan inovasi kebijakan Pemerintah Kota Depok dalam memperluas akses pendidikan bagi keluarga berpenghasilan rendah melalui kemitraan dengan sekolah swasta. Hasil kajian awal menunjukkan bahwa mutu sekolah RSSG di Kota Depok sangat beragam. Dari 47 sekolah pelaksana yang tersebar di 11 kecamatan, tercatat 20 sekolah berakreditasi A, 23 berakreditasi B, dua berakreditasi C, dan dua belum terakreditasi. Total peserta didik mencapai 2.407 siswa. Variasi akreditasi dan sarana prasarana menunjukkan adanya kesenjangan mutu antar sekolah, yang menjadi dasar pelaksanaan pendampingan. Untuk itu, maka perlu dilakukan upaya penguatan mutu sekolah melalui kolaborasi pendampingan RSSG. Universitas Negeri Jakarta menjadi institusi yang diberi kepercayaan untuk melakukan kegiatan pengabdian masyarakat melalui kegiatan pendampingan guru dan kepala sekolah. Kegiatan pengabdian masyarakat ini dilaksanakan oleh dosen dan mahasiswa Universitas Negeri Jakarta (UNJ) sebagai bagian dari upaya memperkuat kualitas dan keberlanjutan program. Kegiatan pengabdian meliputi dua fokus utama: (1) pendampingan guru di 47 sekolah RSSG melalui empat siklus pelatihan tematik penguatan pemahaman karakteristik siswa, implementasi deep learning, model pembelajaran aktif, dan pembuatan media pembelajaran sederhana; serta (2) pelatihan kepala sekolah di Balai Kota Depok bertema “Penguatan Branding dan Budaya Sekolah” yang diikuti oleh 47 kepala sekolah, Hasil kegiatan menunjukkan peningkatan pengetahuan dan kapasitas guru dalam mendesain pembelajaran bermakna, kontekstual dan relevan dengan kebutuhan siswa, serta tumbuhnya kesadaran kepala sekolah dalam membangun identitas dan budaya positif lembaga. Program ini tidak hanya memperbaiki mutu teknis pembelajaran, tetapi juga memperkuat ekosistem kolaboratif yang mendukung keadilan pendidikan di Kota Depok.
