This research aimed to build an index of heritage city sustainability in Malaysia. The method used was quantitative with a field survey design. Ten heritage cities listed in the Malaysian Architectural Heritage Inventory Study Report were utilized as the study areas: George Town, Melaka City, Taiping, Kuala Kubu Bharu, Jugra, Tampin, Muar, Kota Bharu, Kuala Lipis, and Kuching. A total of 1000 respondents were recruited utilizing cluster sampling and a simple random sampling method. The data were analysed with factor analysis methods as well as descriptive and index formulas. The results show that the sustainable heritage cities are Melaka City (0.85) and Muar (0.75). The moderately sustainable ones are Kota Bharu (0.71), George Town (0.68), Taiping (0.67), Kuching (0.67), Jugra (0.63), Tampin (0.60) and Kuala Lipis (0.58). Meanwhile, Kuala Kubu Bharu (0.47) is less sustainable. This analysis implies that heritage cities can be arranged according to their respective levels of sustainabi.....

This study aims to create a thematic spatial model of environmental carrying capacity for sustainable agriculture. The model was made with interpretation, surveys, and scoring an index for each modeling unit as the maximum level of resource for all ecosystem services using a GIS. The data analysis was carried out descriptively with an environmental approach for each unit in the entire region based on the results of ecoregion and land cover overlays. The results are in the form of thematic spatial models, environmental carrying capacity, and sustainable agriculture for each data used including the activity center model. Based on the results of this study, the future implications for the environmental carrying capacity model can be the basis for making RTRW, therefore this research can be used as one of the guidelines in making policies for an area, especially related to planning that is used as strategic land for regional development planning. 2023 WITPress.
