Abstract

Krisis energi global dan rendahnya literasi energi bersih di kalangan pelajar mendorong perlunya edukasi teknologi alternatif yang berkelanjutan. Kegiatan pengabdian ini dilatarbelakangi oleh kebutuhan untuk meningkatkan wawasan siswa terhadap teknologi energi terbarukan, khususnya fuel cell. Tujuan kegiatan ini adalah untuk memperkenalkan prinsip dasar kerja teknologi fuel cell serta membangun pemahaman dan keterampilan awal siswa Sekolah Menengah Kejuruan (SMK) sebagai bagian dari edukasi transisi energi hijau. Pengumpulan data dilakukan sebagai langkah evaluatif untuk meninjau keberhasilan kegiatan PkM. Tolok ukur keberhasilan ditentukan berdasarkan peningkatan pemahaman kognitif siswa serta tingkat partisipasi dan respons positif terhadap materi pelatihan. Metode pelaksanaan menggunakan pendekatan pelatihan interaktif, pendidikan masyarakat, dan substitusi ipteks. Peserta kegiatan berjumlah lebih dari 50 siswa jurusan Bisnis dan Manajemen di SMK Swasta Nurul Amaliyah Tanjung Morawa. Teknik pengumpulan data mencakup pre-test dan post-test untuk mengukur peningkatan pemahaman, observasi untuk menilai keterlibatan siswa, serta wawancara semi-terstruktur untuk menggali persepsi dan ketertarikan siswa terhadap teknologi energi bersih. Analisis data dilakukan secara deskriptif kuantitatif dan naratif. Hasil menunjukkan adanya peningkatan skor pemahaman peserta dari 42% menjadi 81%, disertai partisipasi aktif dan ketertarikan tinggi terhadap materi. Peserta juga mampu mengaitkan prinsip kerja fuel cell dengan peluang usaha berbasis energi bersih. Kegiatan ini membuktikan bahwa edukasi ipteks lintas disiplin dapat menjembatani kesenjangan pemahaman teknologi dan membentuk kesadaran technopreneurship. Oleh karena itu, model pelatihan ini berpotensi diterapkan secara lebih luas dalam satuan pendidikan vokasi non-teknik untuk mendukung transisi energi nasional.

Abstract

Multi-story buildings with vertical irregularities often experience uneven load distribution, which can affect the structural performance under lateral loads, particularly seismic forces. Vertical irregularities, such as varying column and beam dimensions between floors, can lead to significant increases in displacement and deformation on the upper floors compared to the lower floors. Therefore, it is crucial to evaluate the impact of vertical irregularities on the structure's behavior to ensure building safety. This study aims to analyze the impact of vertical irregularity on the behavior of multi-story buildings using the nonlinear pushover method. The analysis was performed using SAP2000 software to assess the structural capacity to withstand lateral loads, particularly seismic loads. The results show a significant linear relationship between story displacement and lateral forces (R² = 0.8898), as well as the impact of vertical irregularities that increase story drift and story drift ratio on the upper floors. The increase in story drift ratio exceeding the earthquake design standard limits may affect the stability of the structure. Furthermore, this study reveals that vertical irregularity can cause significant differences in forces on columns and beams between the lower and upper floors, increasing the risk of structural failure. Based on these findings, it is recommended to consider vertical irregularities in the design of multi-story buildings, accounting for a more uniform distribution of forces throughout the building to ensure structural resilience against seismic loads.

Abstract

Concrete is a primary material in construction with significant environmental impacts, especially due to the use of cement and natural aggregates. One alternative to reduce this impact is by utilizing waste rubber as a partial replacement for coarse aggregate in concrete production. This study aims to evaluate the effect of adding waste rubber on the mechanical properties of concrete, particularly compressive strength and workability. In this study, waste rubber was added at 5%, 10%, and 15% of the total weight of coarse aggregate. Slump tests were conducted to measure the workability of the concrete, while compressive strength tests were carried out at 14 and 28 days to evaluate the development of the concrete’s strength. The results of the study show that concrete with added waste rubber exhibited better workability, indicated by higher slump values compared to normal concrete. Although the compressive strength of concrete with waste rubber was slightly lower at 14 days, at 28 days, the strength significantly increased. This study suggests that waste rubber can be used as an alternative coarse aggregate in concrete, considering the appropriate proportion to achieve a balance between the strength of the concrete and environmental sustainability.
