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

Peripheral areas are areas on the outskirts of a city that usually have the structure and characteristics of a combination of village and city, both socially, physically, economically, and culturally. The outskirts of Surakarta City include the surrounding regency i.e., Sukoharjo, Boyolali, Karanganyar, Wonogiri, Klaten, and Sragen Regency. These areas have potential tofu and tempeh industry. This research was conducted to determine the spatial distribution patterns and factors influencing the location of tofu and tempeh traders. Data was collected using a questionnaire and analyzed using the average nearest-neighbor pattern. The results show that the spatial distribution pattern is dispersed. Dispersed means that each area is evenly distributed and far from other areas. This happens because the ANN (Average Nearest Neighbor) value is >1. The influencing factor for the location of tofu and tempeh traders in the markets is the location chosen relatively close to where tofu and tempeh traders live so that the distance is not too far. The location was chosen because it has been running a business for generations. The location has good facilities and cleanliness, making it comfortable to carry out buying and selling transactions. This place is busy with buyers from various regions
