Abstract

The increasing human reliance on electricity, driven by rapid technological advancement, continues to depend largely on non-renewable fossil fuels, raising critical concerns about energy sustainability and environmental degradation. This study aims to explore the potential of biomaterials as alternative platforms for enhancing the performance of Triboelectric Nanogenerators (TENGs), using a scoping review approach. A systematic literature review was conducted utilizing the Scopus, Crossref, and Google Scholar databases, guided by the PRISMA Extension for Scoping Reviews (PRISMA-ScR) framework. Relevant studies were analyzed based on publication trends, types of biomaterials employed, synthesis methods, operational mechanisms, and key electrical output parameters. The findings indicate that biomaterials such as cellulose, chitosan, and natural proteins exhibit promising triboelectric properties, contributing to improvements in energy conversion efficiency, biocompatibility, and operational stability of TENGs. Further research is recommended to optimize material structures and surface modifications to enhance charge transfer mechanisms. Additionally, the incorporation of carbon-based materials such as graphene and MXene with biomaterials has demonstrated significant potential to amplify device performance. This review also underscores the wide-ranging applications of biomaterial-based TENGs in wearable electronics, biomedical sensing, and eco-friendly energy systems. Overall, this study provides a comprehensive overview and valuable insights into the strategic role of biomaterials in advancing next-generation green energy technologies.

Abstract

This study successfully synthesized Magnetic Iron Oxide Nanoparticles (MIONs) through two different processes, namely mechanical synthesis (MIONs – M) and chemical synthesis (MIONs – N). The synthesized samples were characterized using X-Ray Fluorescence (XRF), Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), and Vibrating Sample Magnetometer (VSM) to determine the elemental composition, morphology, structure, and magnetization of the samples. XRF analysis revealed that iron (Fe) dominated both samples, with concentrations reaching 93.91% for MIONs – M and 89.91% for MIONs – N. SEM morphological analysis showed that the MIONs tended to be spherical and experienced agglomeration, with particle size distribution around 120 nm for MIONs – M and 30 nm for MIONs – N. XRD data indicated that both samples exhibited a cubic spinel Fe3O4 phase, consistent with the AMCSD 0000945 model data. Using the refinement method and Debye-Scherrer equation, the crystallite size and density of MIONs – M were found to be larger than MIONs – N. This correlates with VSM data analysis, where the saturation magnetization of MIONs – M (49.51 emu/g) was greater than that of MIONs – N (26.54 emu/g). These results provide important insights into the characteristics of MIONs and their implications for technological and industrial applications.

Abstract

Magnetite (Fe3O4) is a spinel-based material that has broad potential in various applications, one of which is for magneto-optics. However, the value of the energy gap obtained from magnetite is too small to be applied. Efforts to improve these characteristics are carried out through transition metal ion doping techniques, one of which is cobalt (Co2+) which is known to modify the electronic structure and stabilize the crystal lattice. This study aims to analyze the optical properties of magnetite nanoparticles that have been doped with Co2+ through energy gap and Urbach energy calculations. The synthesis of Co0.125Fe2.875O4 was carried out using the coprecipitation method. Furthermore, characterization was carried out using UV–Vis spectroscopy and analyzed the size of the energy gap and Urbach energy. The results showed that cobalt doping (Co0.125Fe2.875O4) produced two indirect energy gap values ​​of 2.07 eV and 3.19 eV and one direct energy gap value of 3.63 eV. Urbach energy analysis revealed a very low Eu value of 0.0073 eV, indicating high crystal regularity and minimal structural defects in the material. This study demonstrated that cobalt doping not only increases the band gap energy of magnetite but also significantly lowers the Urbach energy, resulting in a material with more pronounced optical properties.

Abstract

Melanjutkan studi ke perguruan tinggi merupakan impian banyak tamatan SMA sederajat. Untuk mewujudkannya, calon mahasiswa harus mempersiapkan diri dengan belajar dan bekerja keras, terutama bagi mereka yang tidak lolos jalur SNBP (Seleksi Nasional Berdasarkan Prestasi) dan harus menghadapi tes UTBK (Ujian Tulis Berbasis Komputer). Program pengabdian ini bertujuan memberikan pengalaman kepada siswa kelas XII tentang bentuk dan tingkat kesulitan tes masuk Perguruan Tinggi Negeri (PTN) serta cara penyelesaiannya. Pengalaman ini membantu siswa mengukur kesiapan mereka dalam menghadapi UTBK sekaligus memotivasi mereka meningkatkan waktu, kualitas, dan kuantitas belajar. Pelaksanaan program terdiri atas tiga tahapan: persiapan, pelaksanaan, dan evaluasi. Kegiatan utama meliputi: (1) review konsep matematika dasar, (2) ujicoba tes pengetahuan kuantitatif dan penalaran matematika, serta (3) pembimbingan soal ujicoba oleh tim. Hasil ujicoba menunjukkan kemampuan siswa dalam pengetahuan kuantitatif dan penalaran matematik masih rendah. Namun, pembimbingan terstruktur meningkatkan pemahaman siswa, menyadarkan mereka akan banyaknya materi yang perlu dipelajari, dan mendorong semangat belajar. Program ini juga membantu siswa lebih memahami jurusan yang diminati. Direkomendasikan kepada pihak sekolah untuk memberikan pembinaan intensif kepada seluruh siswa guna meningkatkan peluang lulus seleksi masuk PTN.

Abstract

Batik is an Indonesian cultural heritage that embodies deep philosophical values and national identity. However, traditional batik-making techniques are often considered complex for beginners since they require specific skills. Therefore, the tie-dye technique, also known as batik ikat celup, is introduced as a simpler and more accessible alternative that can serve both as a learning medium and as an entrepreneurial opportunity. This community service program was conducted at Pondok Pesantren Al-Intishor, Mataram, involving 9th and 10th grade students. The method included delivering introductory materials, demonstrations, and hands-on practice in small groups under intensive guidance. The results revealed high enthusiasm among both students and teachers, who acknowledged the relevance of this activity to be integrated into craft and entrepreneurship education. Students successfully understood the stages of tie-dye batik making—from material preparation to the drying process—while also developing creativity through unique motifs and color variations. This program proved effective not only in enhancing knowledge about batik but also in fostering practical skills, self-confidence, and basic entrepreneurial potential. Thus, tie-dye batik training can be regarded as a strategic medium to preserve cultural heritage while simultaneously improving participants’ economic independence.

Abstract

Indonesia is a country with high tectonic activity and frequently experiences earthquakes that can result in significant damage and casualties. One of the earthquake-prone areas is West Lombok Regency, West Nusa Tenggara. To increase disaster awareness and preparedness, an earthquake mitigation outreach program was conducted at SMA Negeri 1 Kuripan. This activity used a participatory–educational approach through interactive presentations, discussions, and the delivery of material using the educational song “Kalau Ada Gempa” from BMKG. The results of the activity show an improvement in students’ understanding and enthusiasm regarding mitigation measures and the importance of preparedness within the school environment. This program is expected to serve as an initial step toward developing a disaster-resilient school in West Lombok.
