Revitalisasi Pemukiman Kumuh Permukaan di Indonesia Berbasis Filtrasi Air Limbah Domestik, Bakteri Pseudomonas aeruginosa, dan Pemetaan Sistem Informasi Geografis (SIG) Melalui Program Smart-UV (Smart-Urban Village)
Indonesia is the 4th most populous country in the world with a total population of 273,523,615 people and this figure is still increasing. The increase in population that occurs is not matched by adequate infrastructure development, causing high population density in various regions, one of which is the city of Surabaya. Population density causes various problems, such as slum environments. Clean water crisis is often the main problem that occurs in slum and densely populated environments. One alternative solution to solve these problems is to implement Smart-UV. Smart-UV is a revitalization program in urban slums based on domestic wastewater filtration by utilizing Pseudomonas aeuruginosa bacteria and using Geographic Information Systems (GIS) to map slum areas in urban areas. The purpose of this paper is to explain the concept, application, and feasibility of the Smart-UV program in revitalizing urban slums. This research uses a literature study approach by reviewing information that is in accordance with the topic of the problem. The Smart-UV concept itself utilizes biological organisms in the form of P. aeruginosa bacteria in filtrating domestic wastewater in slum areas. The filtration water is stored in a large reservoir to be used for the activities of local residents. To facilitate the mapping of slum areas, GIS is used which is able to detect the condition of an area based on soil contours, rainfall, and various other geographic spatial factors. The existence of an integrated system in the form of Smart-UV is a new hope for the local community to be able to solve problems related to the clean water crisis and utilize clean water for the needs of improving community welfare.
