Abstract

Saat ini Indonesia masih dihadapkan pada pandemi Covid-19. COVID-19 adalah penyakit yang disebabkan oleh virus SARS-CoV-2 yang merupakan bagian dari tipe virus Corona. Rekomendasi standar untuk meredam transmisi infeksi virus adalah sering cuci tangan menggunakan sabun dan air mengalir. Pada kenyataannya, kebanyakan siswa sekolah masih belum mengetahui bagaimana cara mencuci tangan dengan sabun seperti yang disarankan oleh World Health Organization (WHO). Selain itu juga masih dijumpai kurangnya sarana atau fasilitas cuci tangan yang memadai serta belum cukupnya edukasi tentang mencuci tangan yang baik dan benar. Upaya dalam peningkatan kesehatan bagi siswa-siswi sekolah, tata cara cuci tangan yang benar sesuai dengan yang disarankan WHO maka akan disosialisasikan teknologi otomatisasi berupa alat cuci tangan yang menggunakan sensor inframerah bekerja untuk mengaktifkan module relay berdasarkan ada tidaknya objek yang terdeteksi oleh sensor infra merah, sehingga dapat mengalirkan air dari kran, mengalirkan sabun cair dan uap pengering tangan secara otomatis. Kegiatan pengabdian ini diikuti oleh 32 siswa pada pelaksanaan kegiatan dengan mitra sekolah MTs Parmiyatu Wassa’adah” dilakukan dalam tiga tahap: Tahap pertama (awal) yaitu melakukan sosialisasi kunjungan ke mitra Sekolah, dan  mempersiapkan syarat-syarat administrasi dan koordinasi dengan pihak-pihak LP2M UMA Medan. Tahap kedua  merupakan kegiatan inti yaitu kegiatan yang berupa edukasi dengan metode presentasi, disksusi dan demo alat cuci tangan otomatis dan penegring otomatis. Tahap ketiga yaitu tahap akhir yaitu pengembangan keberlanjutan program  yaitu keseluruhan aspek kegiatan dengan membuat kesimpulan dari hasil kegiatan yaitu berupa video yang diunggah ke youtube, laporan penelitian serta publish jurnal PKM.

Abstract

Abstrak: Kegiatan pengabdian kepada masyarakat ini dilatarbelakangi oleh rendahnya pemanfaatan teknologi digital dalam pemasaran produk pertanian, yang membatasi jangkauan pasar dan daya saing produk biopestisida petani. Tujuan kegiatan ini adalah meningkatkan pengetahuan dan keterampilan petani dalam pembuatan biopestisida serta pemasaran berbasis digital guna memperluas pangsa pasar dan meningkatkan penjualan. Metode pelaksanaan meliputi pelatihan, pendampingan, dan praktik langsung penggunaan media sosial, marketplace, serta penyusunan katalog produk daring. Kegiatan ini diikuti oleh 29 petani. Evaluasi dilakukan melalui pre-test dan post-test serta pemantauan aktivitas digital peserta. Hasil kegiatan menunjukkan peningkatan pengetahuan pemasaran digital sebesar 25%, keterampilan teknis sebesar 30%, dan minat penggunaan platform digital sebesar 40%. Peserta mulai aktif memasarkan produk secara daring dan membangun hubungan dengan pelanggan baru. Kegiatan ini membuktikan bahwa pendampingan berbasis teknologi digital efektif dalam meningkatkan kapasitas dan kemandirian petani.Abstract: This community service activity was motivated by the low utilization of digital technology in agricultural product marketing, which limits the market reach and competitiveness of farmers' biopesticide products. The objective of this activity was to improve farmers' knowledge and skills in biopesticide production and digital-based marketing to expand market share and increase sales. The implementation method included training, mentoring, and hands-on practice using social media, marketplaces, and creating online product catalogs. This activity was attended by 29 farmers. Evaluation was conducted through pre- and post-tests and monitoring of participants' digital activities. The results showed a 25% increase in digital marketing knowledge, a 30% increase in technical skills, and a 40% increase in interest in using digital platforms. Participants began actively marketing their products online and building relationships with new customers. This activity demonstrated the effectiveness of digital technology-based mentoring in increasing farmer capacity and independence.

Abstract

Moisture-induced degradation remains a critical reliability issue in photovoltaic (PV) modules, particularly in humid tropical climates. While biomass-derived carbon materials have been widely investigated for electrochemical applications, their use as functional supporting layers in PV modules remains limited. This study develops potato-derived carbon nanofibers through moderate-temperature carbonization (700 °C, N₂ atmosphere) followed by electrospinning. Structural and chemical properties were evaluated using XRD, FTIR, Raman spectroscopy, and BET surface area analysis. Morphology and fiber diameter distribution were examined via SEM. Electrical conductivity was measured using a four-point probe method. Water vapor permeability (WVP) and biodegradation behavior were assessed to evaluate durability and moisture regulation capability. The synthesized material exhibits predominantly amorphous turbostratic carbon with characteristic D and G Raman bands (ID/IG ≈ 0.92), specific surface area of 186 ± 12 m²/g, and electrical conductivity of 3.8 ± 0.4 S/m. Nanofiber diameters range from 72–108 nm (mean ± SD). Controlled WVP (3200–4100 mg/day/L) and moderate biodegradability (8–12% mass loss over 14 days) indicate balanced vapor diffusion and structural integrity. The results demonstrate the feasibility of potato-derived carbon nanofibers as sustainable moisture-regulating supporting layers in photovoltaic modules.

Abstract

This community service activity is motivated by the importance of the role of electrical engineering students as agents of change in socializing renewable energy in the community. The Electrical Engineering Student Association (HME) and FKHMEI North Sumatra have great potential but still have limitations in the depth of theoretical understanding and the ability to analyze practical problems related to the energy transition. This community service program aims to equip 60 participants through collective education methods and interactive discussions to improve cognitive competence and problem-solving abilities in the field of New and Renewable Energy (EBT). Evaluation of the program's success was carried out quantitatively by comparing pre-test and post-test scores on various competency parameters. The results of the community service showed a very significant increase in competence in participants with all participant assessments. Before the activity, the average participant understanding score only ranged from 70 to 75. However, after the intervention was carried out, there was an impressive surge where the parameters of EBT Knowledge, Energy Transition Understanding, and EBT Understanding reached a perfect score (100). In addition, the problem analysis ability increased drastically by 25 points to 95, which reflects the maturity of students' critical thinking. This activity succeeded in totally transforming students' understanding, preparing them to become competent educators and ready to contribute to realizing an independent electricity environment in the North Sumatra region.

Abstract

The performance of vertical axis wind turbine is strongly influenced by blade characteristics, yet the effect of blade material on turbine performance remains relatively underexplored, particularly for small scale Darrieus type turbines. This study experimentally investigated the influence of acrylic and zinc blade materials on the aerodynamics and energy conversion performance of a three bladed Darrieus vertical axis wind Turbine. A laboratory-scale experimental setup was employed to evaluated turbine rotational speed, torque, and electrical power under a controlled wind speed of 4.3 m/s. The results demonstrate the blade material significantly affects the turbine’s ability to extract and convert wind energy. The acrylic blade turbine achieved a power coefficient (Cp) of 0.293 and an overall conversion efficiency 62.81%, compared with 0.208 and 47.11%, respectively, for the zinc bladed turbine. The acrylic configuration therefore provided approximately 25% higher overall performance than zinc configuration. These findings experimentally validate the importance of blade material selection in the design of small scale Darrieus wind turbines and indicate that acrylic can provide a more effective alternative to zinc for improving wind energy conversion under low speed operating conditions. The results provide practical guidance for material selection in the development of lightweight, low speed vertical axis turbines for decentralized and small scale renewable energy applications.
