Abstract

Metamaterials possess distinct characteristics that make them very suitable for scientific investigation. This phenomenon's hallmark has left scientists perplexed and skeptical. Researchers have conducted numerous studies to explore the composition of one or more metamaterials. This project focused on the development of a linear-sequence metamaterial. Next, we examined the alterations in the optical characteristics of the metamaterial. The utilized frequency range is 0 to 9 GHz. We construct the hexagonal split ring resonance (SRR) metamaterial with a radius of 2.9 mm, consisting of one to four hexagonal SRRs. The findings revealed that the SRR hexagonal metamaterial structure had the highest negative refractive index value, reaching -9.33 in combinations of four hexagonal SRRs.

Abstract

This community service programme aimed to strengthen physics laboratory management and practical activities at three senior and vocational secondary schools in Pekanbaru, Indonesia. Conducted by lecturers and students of the Physics Study Programme, Universitas Muhammadiyah Riau, the programme involved partner assessment, orientation, implementation, and evaluation. Activities included developing Standard Operating Procedures (SOPs), inventorying laboratory equipment, preparing practical modules based on real experiments and PhET virtual simulations, and conducting practical training. Programme outcomes were evaluated through questionnaires administered to students and supervising teachers. Before the programme, 60% of students had never participated in physics practical activities. Following the intervention, all students (100%) reported improved understanding of the practical materials, with 20% reporting very good understanding, 33.3% good understanding, and 46.7% adequate understanding. Furthermore, 93.3% of students expressed positive attitudes towards physics practical activities and actively participated in recording and maintaining laboratory equipment. The programme also supported the development of students’ soft skills, particularly communication, collaboration, and leadership. Overall, the programme demonstrated the potential of university–school collaboration to strengthen laboratory management, enhance physics learning experiences, and provide a sustainable partnership model supporting the implementation of the Merdeka Belajar-Kampus Merdeka (MBKM) policy.
