“…Firat et al (2015) [23] agreed with this scenario, as soil conditions and local sites can influence the soil amplification (this was experienced in the Adapazari region before the Kocaeli earthquake in 1999). Furthermore, Yunita et al ( 2018) [42] found soil amplification factors for Banda Acheh, which is underlain by soft soil up to 4.3. Thus, the soil amplification factor should be used to estimate the amount of vibration received by the ground surface when a seismic event occurs.…”

The existence of soft soil in offshore areas may lead to the amplification of vibration received from offshore facilities, especially from the existing fixed-jacket platforms, which were designed without provision to seismicity, as in Malaysian water. Therefore, this study was designed to develop a seismic microzonation map and a soil amplification factor map according to soil type; we propose horizontal response spectra and site coefficient values (Ca and Cv) for the Malay Basin. A one-dimensional nonlinear analysis of layered soil (NERA) was used in the ground response analysis for six selected seismic events under five return periods of 100, 200, 500, 1000, and 2500 years. Soil amplification factors for soil types D and E showed a decreasing trend from 100 years to 2500 years. Two designed horizontal response spectra are proposed (for soil type D and E) under average and envelope conditions; a comparison with ISO showed that the proposed spectra were higher, especially for soil type E. To summarize, the seismicity effect should be included in the development of offshore industries as findings indicated that soil amplification occurred in soil types D and E at the Malay Basin.

“…Building upon this event, the earthquake parameter becomes an essential component to be considered in this study. The high occurrence of earthquakes in Aceh can be attributed to various factors, including the presence of seismic sources such as subduction zones and the Sumatra fault passing through the region [74][75][76]. In addition to earthquakes and tsunamis, the presence of active volcanoes also underlies the reason why disaster-related parameters are prioritized over others.…”

The strategic siting of logistics distribution centers, particularly within the medical sector, has increasingly emerged as a crucial consideration in optimizing the supply chain. This study focuses on identifying the most advantageous location for a new logistics distribution center in Aceh Province, leveraging the integration of the analytical hierarchy process (AHP) and geographic information systems (GIS) overlay techniques. Parameters were weighted using AHP, and spatial analysis facilitated the classification of zones into three suitability categories: low, moderate, and high. It was determined that the optimal location for the establishment of a new center would be within a high suitability zone. Six potential sites, designated as Locations A through F, were initially identified. Subsequent evaluation, which included considerations of access road availability and the capacity to uniformly service all health-related warehouses, led to the selection of Location C as the most ideal. This selection underscores the importance of comprehensive spatial and hierarchical analysis in the decision-making process for logistics operations, ensuring effective distribution networks within critical sectors such as healthcare.

“…In 2018 Saidi, Aulia, Setiawan, Abdullah, and Hasan [18] simulated typical retail buildings in the city Banda Aceh using a response spectra curve. Yunita, Setiawan, Saidi, and Abdullah [19] investigated the seismic site amplification of the city of Banda Aceh's soft soil. This investigation suggested a ground motion amplification of Banda Aceh's soils of up to 4.3.…”

The city of Banda Aceh-Indonesia is extremely exposed to a significant seismic hazard. There are three main seismic sources around the city which are the tectonic subduction, the great Sumatran fault, and the West Andaman fault. Thus, seismic microzonation study of the Banda Aceh city is urgently required for any mitigation efforts. Site-specific ground response analysis was carried out at eleven sites in the city of Banda Aceh. An analytical model of the equivalent-linear model was used to perform ground response analysis. This analytical model of the equivalent-linear approach has demonstrated that it can simulate, reasonably well, the alteration of seismic motions at the ground surface. Three actual historical time histories recorded at rock sites nearby the city of Banda Aceh, and eleven developed sub-surface models in the city of Banda Aceh, were used to estimate the seismic characteristics, namely the peak ground acceleration, peak ground velocity, fundamental frequency, and estimated site amplification of the investigated sites. The results of the site-specific ground response analysis suggest that: (1) all the eleven sites have been classified as seismic site class D as per the provisions of SNI 1726SNI -2012 (2) the site fundamental frequency in the city of Banda Aceh varies between 0.2 and 1.1 Hz; and (3) the amplification factor of the soils in the city of Banda Aceh can be up to 4.7. The largest spectral velocity and acceleration of the investigated sites were found to be 0.26 cm/s and 0.29 g, respectively.
