Abstract

Mobility reduction is believed to effectively reduce the spread of Covid-19 disease by lowering the SARS-COV-2 transmission in the population. A big data platform consists of a big scale of anonymized smartphone location data collected by Citydash.ai and presented as mobility data during the pandemic time to help humanity control the spreading of Covid-19 in Indonesia. This research aims to find the relation between mobility and population density to the spread of Covid-19 in Yogyakarta City and its surrounding areas, Indonesia, by using GIS to visualize the mobility, population density and Covid-19. This research also used a simple correlation method by making a cross-tabulation of the data to verify the relation between variables. This research found that mobility into Yogyakarta City and its surrounding area relates to its Covid-19 spread. At the same time, this research also found that mobility inside the area, mobility out of the area, and population density did not relate to the expansion of Covid-19 in Yogyakarta City and its surrounding areas. This anomaly should be considered in the Covid-19 mitigation or similar diseases to help public health, data-driven decision-making, and improving community response to Covid-19.

Abstract

The 2004 tsunami disaster caused severe ecological damage in Banda Aceh City, destroying a vast majority of its vegetation cover. This study aims to analyze the spatio-temporal dynamics of post-disaster vegetation recovery over two decades (2004-2024) to identify the stages of ecological succession. Using a remote sensing approach, Landsat satellite imagery from 2004 (pre-tsunami), 2005 (post-tsunami), 2014 (one decade later), and 2024 (two decades later) was analyzed using the Normalized Difference Vegetation Index (NDVI). The NDVI classification results show a drastic change: the non-vegetated area surged from 67.58% in 2004 to 89.01% in 2005, while the dense vegetation class was entirely eliminated. However, a recovery process unfolded over the subsequent two decades. By 2024, the non-vegetated area had drastically shrunk to just 13.11%, while the combined area of moderate and dense vegetation surged to over 45% of the city's total area, surpassing the pre-tsunami condition. This study concludes that Banda Aceh has not only successfully restored its vegetation cover but has also undergone a significant ecosystem maturation phase. These findings provide a robust scientific basis for integrating NDVI analysis as a proactive monitoring instrument into the Banda Aceh City Spatial Plan (RTRW) to support sustainable and disaster-resilient urban development.
