Abstract

This study examines the seismic vulnerability of an irregular educational building with a vegetated roof in Yogyakarta using linear procedures based on ASCE 41-17. Modelling approaches differ Model 1 treats skylights and planter boxes as loads with straight roof slabs, while Models 2 and 3 use shells with sloping roof slabs. Vegetated roofs are featured in Models 1 and 2. The analysis, conducted at seismic hazard levels BSE-1N and BSE-2N using the ETABS program, evaluates structural components and compares Response Spectrum (RS) and Linear Time History (LTH) methods. Results show seismic weight variations of 1.20% to 15.04% between models. Model 1 fails to meet the criteria for modal analysis, while Models 2 and 3 do. The structural performance evaluation based on average demands at BSE-1N and BSE-2N levels varied from Immediate Occupancy to Life Safety performance. The LTH method in all models had higher acceptance ratios than the RS method.

Abstract

Wilayah Kota Parepare merupakan salah satu daerah rawan banjir akibat kombinasi topografi dataran rendah, curah hujan tinggi, dan sistem drainase yang belum optimal. SMK Negeri 1 Parepare menjadi salah satu sekolah yang terdampak banjir, namun belum memiliki program edukasi kebencanaan yang terstruktur. Kegiatan pengabdian ini bertujuan untuk meningkatkan pemahaman dan kesiapsiagaan siswa terhadap risiko banjir melalui edukasi mitigasi berbasis ceramah, diskusi interaktif, dan pemutaran video simulasi. Metode pelaksanaan terdiri dari empat tahapan: perencanaan, persiapan, pelaksanaan, dan evaluasi. Sebanyak 71 siswa terlibat dalam kegiatan yang diselenggarakan di aula sekolah. Penilaian pemahaman dilakukan dengan metode pretest dan post-test menggunakan soal pilihan ganda yang relevan dengan materi mitigasi banjir. Hasil pretest menunjukkan rata-rata pemahaman awal sebesar 70,49%, dengan sebagian besar siswa berada pada kategori sedang hingga rendah. Setelah kegiatan edukasi, rata-rata nilai post-test meningkat signifikan menjadi 90,14%, menunjukkan adanya peningkatan pemahaman sebesar 30,47%. Peningkatan ini mengindikasikan bahwa pendekatan edukatif yang digunakan efektif dalam meningkatkan literasi kebencanaan di kalangan siswa. Dengan demikian, kegiatan pengabdian ini dinilai berhasil dalam membekali siswa dengan pengetahuan dasar dan kesiapsiagaan menghadapi bencana banjir di lingkungan sekolah.

Abstract

Accurate structural modeling is essential for reliable seismic performance evaluation, yet default software settings in finite element analysis tools are frequently adopted without adequate calibration. This study investigates the sensitivity of seismic response in a five-story reinforced concrete hospital building to three key modeling parameters: shell element mesh size, insertion point configuration, and beam end length assumption. A mesh convergence study was first conducted across six discretization levels to identify an optimal mesh size. Subsequently, four structural models were developed using a Design of Experiment (DoE), with M1 (top insertion point, clear length) serving as the reference baseline. Linear seismic analysis was performed using the Equivalent Lateral Force (ELF) method in accordance with SNI 1726:2019, with natural period, base shear force, and story displacement adopted as response indicators. Results show that a 1 m mesh size provides an optimal balance between accuracy and computational efficiency. Insertion point configuration was identified as the dominant parameter, with centroid-based models producing up to 21% longer natural periods and 46% greater story displacements compared to M1. Base shear was exclusively governed by the end length assumption, as the ELF method renders it insensitive to stiffness-related parameters.
