Assessment of Old Buildings in Lasem City Based on Tiered Quantitative Analysis Method with Weighting Factors

Old buildings in Lasem City are a historical heritage from the colonial period. Based on Law Number 11 of 2010 on Cultural Heritage, these buildings can be categorized as Cultural Buildings if they have gone through the process of registration and assessment and finally designated by the government according to their rank. The assessment of old buildings in Lasem City which are considered to have the characteristics of a cultural heritage building must be performed first as a basis for making recommendations for the government in making the designation as cultural heritage buildings following applicable laws and regulations. The assessment of cultural heritage, especially from the types of building objects has been performed mainly in the context of preparing recommendations for designation, but the assessment mechanism applied is unknown. Therefore, this research introduces the mechanism of assessment model that applies tiered quantitative analysis methods with weighting factors. This method is commonly used in various research in the exact sciences, especially in evaluating land. This method is an adaptation of the spatial analysis method based on the algorithm. The results of the assessment with this model will be able to formulate the expected formula as well as can produce the final value for building object in order to obtain a class in relation to recommendations for designation as cultural heritage buildings. In this research, four recommendation classes were proposed, namely building which is not suitable or not recommended, recommended building with sufficient level, recommended building with strong level, and recommended building with urgent level. These four levels are closely related to the priority scale in a series of designation as cultural heritage buildings. The results of this research are expected to obtain a quantitative value and scientifically measured in the procedure for assessing buildings for designation as cultural heritage buildings.
