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

Microactuators play a vital role in several microelectromechanical systems (MEMS) that generate forces or deflections necessary to accomplish functions such as scanning, tuning, manipulation, or delivery. Utilizing a ferrite magnetic core has shown the potential to enhance the deflection of the microactuator. However, the previous study presented a complex fabrication method with high power consumption unsuitable for micropump application. Herewith, we report the impact of ferrite core length on the deflection generated by a microactuator with a simple fabrication method. The deflection behavior shows that the corresponding magnetic core length is inverse to the deflection improvement. The force reduction generated led by a longer magnetic core because of the farther distance to the coil. Our study can be used as a reference to support the development of micropump or active micromixer devices, which require compact devices with simple fabrication and high deflection, achieving ultra-high flow rate and high mixing index.

Abstract

Migrant workers often face challenges in maintaining a healthy quality of life due to various factors, including unsupportive work environments, lack of access to healthcare facilities, and unhealthy lifestyles. In addition, the increase in carbon emissions related to human activities has become a global issue that requires serious attention. Combining efforts to improve quality of life with steps to reduce carbon emissions can help achieve the SDGs, namely good health and well-being, clean water and sanitation, affordable and clean energy, and climate action. This Community Service Program (PkM) aims to: (1) improve healthy living quality through education and implementation of healthy lifestyles, (2) raise awareness about the importance of maintaining health and the environment simultaneously, and (3) reduce the carbon footprint by promoting low-carbon lifestyles. The method used is an integrated approach that involves four stages: (1) education and training through seminars and workshops, (2) facilitating access to healthcare facilities, (3) campaigns and mentoring to encourage lifestyle changes, and (4) evaluation and monitoring to measure the program's impact. The results of this program show that migrant workers have high awareness in adopting healthy and low-carbon lifestyles, although improvements are still needed in some areas such as recycling and the selection of low-carbon products. In conclusion, this program can make a real contribution to improving the quality of life of migrant workers while reducing negative environmental impacts. Recommendations for future programs include strengthening recycling campaigns and increasing awareness of low-carbon product consumption.

Abstract

In today’s digital era, students face challenges in developing critical thinking and problem-solving skills essential for success in an increasingly complex world. Computational Thinking (CT) has emerged as a pivotal 21st-century skill for innovation and problem-solving. This study investigates the impact of STEM-based learning through a water turbine project on students’ CT and Learning Engagement (LE) at the secondary school level. A quasi-experimental approach with a pretest-posttest control group design was employed. The participants were 76 of 445 8th-grade students from secondary schools in Bandung, Indonesia, divided equally into experimental and control groups, each comprising 38 students. Statistical analyses using the Mann-Whitney U test on n-gain scores revealed a significant improvement in CT for the experimental group compared to the control group (U = 50.00, sig.). < 0.001, and a large effect size (r = 0.80). Similarly, LE in the experimental group increased significantly compared to the control group (U = 10.50, sig.). < 0.001, and a large effect size (r = 0.85). These results highlight that STEM learning through the water turbine project effectively enhances students’ CT and LE. This study demonstrates the potential of STEM-based approaches to foster essential 21st-century skills among secondary school students. However, further research is needed to explore its application across diverse contexts and skill areas.
