Abstract

Yogyakarta as a city of education and a tourism city has the potential to experience a very significant change in the concentration of anthropogenic activity between before the pandemic and when the lockdown policy was implemented. Also, during the pandemic transition period, it allows for changes in fluctuating thermal comfort. This study aims to analyse thermal comfort before the pandemic, lockdown, and transition of the Covid-19 pandemic in Yogyakarta City. This study utilised Landsat 8 images before the pandemic, lockdown, and the transition to the Covid-19 pandemic. Next, the land surface temperature (LST) and Normalized Difference Moisture Index (NDMI) were extracted. The LST and NDMI values are then processed to obtain thermal comfort in the form of the Modified Temperature-Humidity Index (MTHI). There was no clear pattern regarding MTHI (as a proxy of thermal comfort) before the pandemic, during the lockdown, and during the Covid 19 pandemic transition in the City of Yogyakarta. This study confirmed that there is a need of a better spectral index that reflects thermal comfort condition of a region.

Abstract

Disparity in the distribution of educational facilities in developing regions is an issue to achieve equity in access to education. For example, access to senior high school (SMA) and vocational high school (SMK) has remained unequal across different sub-districts within West Bandung Regency of Indonesia and will pose a problem in attaining 12 years of compulsory education. In this research, the methods of remote sensing and GIS were integrated for analyzing the spatial distribution and accessibility to senior and vocational high school. Using data from Google Maps in 2021 and Sentinel imagery, the ANN and kernel density methods have been used in identifying the distribution pattern, while conducting buffer analysis to map coverages. In fact, there is a clustered distribution in sub-districts like Lembang, Padalarang, and Cipongkor, with isolated sub-districts like Parongpong and Rongga showing huge accessibility gaps where settlement exists over 7.5 km away from the school. These findings raise awareness of the pressing need for concerted infrastructure planning and investment at sub-national levels in pursuit of equal opportunities that are imperative for sustainable development and social equity in developing countries.
