An unexpected growth of slum settlement has been happening in most of Indonesian cities. âKampung Bragaâ is one of the slum areas located in one of strategic areas in the centre of Bandung city. It is an enclave that lies along the side of Cikapundung river and surrounded by the tourism area. This research analyzed characteristics and untidiness level of âKampung Bragaâ. The untidiness level assessment was based on dimensions (aspects) stated by Minister of Public Works and Housingâs Regulation no. 02/PRT/M/2016 regarding housing and slum area quality development: (1) building; (2) surrounding road; (3) water; (4) drainage; (5) waste management; (6) trash management; and (7) fire security. This research also formulated composite index that can be used in area quality assessment. The index consists of the following aspects or indicators: (1) The buildingsâ density; (2) peopleâs density per lot; (3) availability of infrastructures and utilities; (4) availability of open public space; (5) inexpediency to areaâs spatial planning; and (6) lotâs ownership. The index was determined or calculated based on weighted average of those indicators. The results show that(1) most of the residents are small (low scale) entrepreneurs in trading, with low level of education and income; (2)most of the buildings are under 45 m2, occupied by 8 people (mostly consists of 2 households), lie on high density location, and in improper condition; (3) Low level infrastructures (road, water, waste treatment facility, drainage, and green area); and (4)spatially, the buildings lie irrelarly, and some of those are also located at the bank of Cikapundung river. The overall condition is also reflected in the result of the quantitative assessment that the quality of âKampung Bragaâ is categorized as âVery Lowâ which score of 0.25 (0.00 â 1.00 scale), and âVery High Slumâ (score 88).
