The Chinatown area is a historic area that has a high building density and has a grid-shaped pattern due to its function as trade and services. The various designations of the area function so that the high activity is carried out outside the room, especially on weekends. This study aims to provide direction for environmental management in the Chinatown area of Semarang City as an effort to mitigate climate change disasters with the concept of Climate Sensitive Urban Design. Data obtained by field observations then identified the Building Coverage Ratio (BCR) and floor area Ratio (FAR). Measurement of air temperature, wind speed and humidity is carried out in the morning, afternoon and evening. Simulated data using ArcGis 10.3 to test the thermal comfort. Based on that, the Chinatown is classified as Uncomfortable area more than 27 ° C. The microclimate of the Chinatown area is influenced by landuse, building, and the frequency of traffic. So the concept of the climate sensitive urban design is suitable for the Chinatown area with optimization of the potted plants, hanging plants on the canopy, vine vegetation on walls and use public transportation modes to the area.

“…Land use change and illegal logging trigger approximately 85% loss of green open spaces assumed to also contribute to the rising temperatures. Major cities, including Semarang continue to expand and in turn consequently convert agricultural land for building purposes (Pamungkas et al, 2019). Over the last decade, land use diversion had significantly expanded by 13%.…”

Indonesia reported a maximum annual temperature rise of 0.3°C in urban regions. Semarang, the largest metropolitan city in the province of Central Java, is also experiencing an increase in temperature due to climate change therefore activities in urban public spaces are disrupted due to the absence of a comfortable temperature. Urban design elements, including land cover materials, road geometry, vegetation and traffic frequency expressed significant effects on micro-climate. Measurement of Thermal Comfort in Urban Public Spaces Semarang was carried out s at the micro level as an old historical district The Old Town and Chinatown. This increment indeed influences thermal comfort level in its outdoor environments which are important for comfortability of outdoor activity. This study aims to analyse surface temperature through Thermal Comfort Measurement. Data was obtained by measuring air temperature, wind speed and humidity in the morning, afternoon, and evening. Inverse distance weighted (IDW), thermal comfort calculations and micro-climate model were employed to evaluate existing physical conditions of these settlements. The results showed both Old Town and Chinatown observed thermal comfort value above 27°C and are categorized as uncomfortable for outdoor activities. This research is contributing to the need to further develop public spaces to potentially adapt to environmental changes.

“…So that the phenomenon that occurs at this time is an increase in city temperatures that are very extreme or often referred to as the Urban Heat Island (UHI) phenomenon. According to research conducted by Pamungkas [2], cities in Indonesia such as Semarang City continue to experience the growth of built-up land. The increase built of land built in the city of Semarang in the past 10 years reached 13% with the most land-use change in the agricultural area.…”

The city of Semarang is one of the cities in Indonesia that experiences the phenomenon of heat stroke due to climate change. These conditions cause an increase in the average surface temperature of the city to 22-40 ° C which is included in the category of discomfort for outdoor activities. This is certainly very disturbing for various forms of outdoor activities, such as pedestrian activity. The Old City of Semarang is included in the public area which in the last 5 years seeks to improve the arrangement of the area through the development of pedestrian ways. However, the development that has been carried out is considered not able to create a comfortable climate for pedestrians due to high regional temperatures, especially during the day. For this reason, this study aims to examine how to create a comfortable pedestrian ways to climate change, especially in the Old City Region of Semarang. The method used in the form of analysis of the level of thermal comfort using the ArcGIS application and pedestrian ways analysis using vegetation distribution and building shadow analysis. The result will be found elements of city design that can create pedestrian comfort in the Old City Region of Semarang.
