影响市政当局的主要问题之一是固体废物管理。选择合适的地点处理废物是有困难的，因为在选址前会考虑不同的因素。目前，柔佛州的垃圾产生量在过去几年中稳步增加，现有的唯一卫生填埋场即将达到容量极限，这意味着需要建设一个新的卫生填埋场。本研究利用地理信息系统(GIS)和层次分析(AHP)方法，集成未来人口和垃圾产生量预测等动态数据，为研究区卫生填埋场的建设提供合适的场地。这项研究考虑了13个标准，即水体、土壤、地质、坡度、海拔、居民区、考古遗址、机场、人口、道路、铁路、基础设施和土地利用。用层次分析法从两两比较矩阵中确定每个标准的权重。对稠度指数和稠度比进行了检验，确定为适宜的稠度指标。利用加权叠置分析工具，将层次分析法得到的结果赋值给地理信息系统环境中的各个准则。制作了最终的潜在垃圾填埋场地图，并确定了三个最合适的潜在垃圾填埋场。
One of the major problems affecting municipalities is solid waste management. There is a difficulty in selecting suitable sites for waste disposal as it involves different factors to be considered before site selection. Currently, waste generation in Johor Bahru has steadily increased over the last few years and the only existing sanitary landfill is reaching its capacity limits, which means that a new sanitary landfill site needs to be constructed. In this study, geographic information system (GIS) and analytical hierarchy process (AHP) methods were utilized with the integration of dynamic data such as future population and projection of waste production in order to provide suitable sites for the construction of a sanitary landfill in the study area. Thirteen criteria were considered for this study, namely water bodies, soil, geology, slope, elevation, residential areas, archeological sites, airports, population, road, railway, infrastructure, and land use. AHP was used to determine the weights for each criterion from the pairwise comparison matrix. Consistency index and consistency ratio were checked and confirmed to be suitable. The results obtained from AHP were assigned to each criterion in GIS environment using weighted overlay analysis tool. The final potential site map was produced, and the three most suitable potential landfill sites were identified.
