Abstract

 This study evaluates the impact of Soil-Structure Interaction (SSI) on the dynamic response of low-rise school buildings in Indonesia. Three SSI models were developed: spring supports (SSI I), distributed springs on a plate (SSI II), and soil modeled as solid elements (SSI III), compared to a benchmark model. The analysis revealed that SSI III produced the highest displacement, shear force, and overturning moment responses but required significantly longer computation time. In contrast, SSI II demonstrated more efficient results by reducing internal forces and structural displacement. This study provides insights into the implementation and contribution of SSI modeling in structural analysis.

Abstract

Landslides are events that can cause both moral and non-moral losses, one of which is the damage to the Subulussalam–Lipat Kajang Road section at KM. 619+900, resulting in restricted movement and disrupted activities of the local community. This could be due to factors such as rainfall or groundwater levels. Therefore, this research was conducted with the aim of addressing the existing problems by providing appropriate and effective solutions to the landslides caused. This research uses secondary data and primary data in analyzing slope stability. The initial conditions and the slope conditions following sheet pile reinforcement are used this analysis. An application called Plaxis is required in order to examine the slope stability. This study produced a safety factor value of 1.104 under existing conditions, and after being reinforced with sheet piles, the safety factor value increased to 1.502. However, if the slope in the existing condition is subjected to an earthquake load, it will obtain a very low safety factor value of 1.044, and this requires strengthening with sheet piles and anchors to increase the safety factor value, ensuring that the slope is in a stable condition. This research provides one of the much-needed alternatives in addressing landslide issues, especially in the fields of construction and geotechnical engineering. The findings of this research can serve as a reference or guideline in the civil engineering planning process, particularly in the use of reinforcement systems such as sheet piles (retaining walls) and anchors as effective solutions.

Abstract

Struktur bangunan ini selesai pada tahun 1998 dan didirikan di atas endapan aluvium (Qh). Gedung ini telah melewati beberapa gempa besar salah satunya yaitu Gempa dan Tsunami 2004. Oleh karena itu perlu dievaluasi ulang mengikuti standar peraturan gedung terbaru yaitu SNI 1726:2019. Penelitian ini bertujuan untuk mengevaluasi perilaku struktur bangunan setelah masa layan 24 tahun yaitu berupa perpindahan, gaya geser dasar, dan level kinerja struktur sesuai ASCE 41-17. Gedung ini memiliki panjang 29,4 m, lebar 13 m dan tinggi 14,4 m. Pada penelitian ini digunakan analisis pushover dibarengi pengecekan frekuensi alami gedung existing dengan alat mikrotremor untuk membandingkan perilaku struktur di awal desain dan terhadap kondisinya pada saat ini. Pemodelan menggunakan program ETABS, dari hasil evaluasi didapatkan level kinerja gedung sesuai perencanaan awal berdasarkan push x yaitu immediate occupancy dan push y termasuk ke dalam life safety. Kemudian level kinerja gedung setelah masa layan 24 tahun berdasarkan push x dan push y keduanya termasuk ke dalam kategori life safety. Dari segi kekakuan gedung dalam menahan perpindahan akibat beban pushover juga mengalami penurunan setelah 24 tahun, hal ini bisa diketahui dengan base shear yang sama perpindahan gedung setelah masa layan 24 tahun lebih besar dibandingkan gedung yang sesuai dengan perencanaan awal.

Abstract

This community service program was conducted to address the clean water crisis experienced by flood-affected residents in Gampong Keurumbok, Kecamatan Kuta Blang, Kabupaten Bireuen. The flood disaster damaged and contaminated local water sources, disrupting the community’s access to safe water for daily needs. The program aimed to provide a reliable and sustainable clean water supply through the construction of a shallow tube well and to enhance community capacity in managing and maintaining water facilities. The target beneficiaries were households affected by the flood and facing limited access to clean water. A participatory approach was employed, including needs assessment, site survey, technical planning, tube well construction, and community assistance. The implementation strategy involved coordination with village authorities, site selection based on local hydrogeological conditions, and active community participation throughout the construction and maintenance processes. The results indicate that the shallow tube well successfully improved access to clean water, reduced dependence on contaminated water sources, and supported post-disaster recovery efforts. Furthermore, community involvement in the management of the facility contributed to the sustainability and long-term utilization of the clean water supply system.
