Vulnerability of the Semarang Heritage Area to Climate Change

Semarang is a coastal city with many historical buildings as a relic of past civilisations. Along with the recent worsening of climate change, these historic structures are in danger of damage. If this condition persists, historic buildings will be lost. This study aims to determine the vulnerability of historic buildings in four different landscape conditions to climate change indicators, such as temperature, air quality, object shading, activity level, and vegetation. The analysis process on the sample measurement data is in the form of vulnerability identification based on landscape characteristics via climate parameters, followed by the final assessment process of environmental adaptability and vulnerability level of historic buildings using the Range Analysis Method (RAM). A standardisation approach to the value of each indicator strengthens this. The spatial approach method was carried out on the final results of the vulnerability assessment to produce a Vulnerability Map for the Semarang Heritage Area. The outcomes obtained in the form of community beliefs and habits significantly impact the building maintenance level. Locations with a solid attachment for trade and religious activities are more likely to care for historic buildings. The influence of regulations and the government's commitment to handling the impacts of climate change is also very influential in reducing the value of vulnerability in the Semarang Heritage Area. Locations close to the coast tend to have a low level of vulnerability due to the high focus on environmental management in these locations.
