An evaluation was undertaken of four selected social impacts of the Integrated Urban Infrastructure Development Program (IUIDP) on the community in three kelurahans in Western Java (Jamika, Warung Muncang, and Maleber), with particular emphasis on low income people, using Social Impact Assessment methods. The impacts studied were changes in employment, household income, land and rental values. The evaluation suggests that the execution of the IUIDP generated beneficial as well as adverse effects. The beneficial effects include that the program created employment for several residents in the study areas and generally improved the household income of the residents concerned. Also some benefits have accrued to a number of land owners as the value of their land increased. Other benefits identified include improved access, water supply, sewerage and garbage services. The adverse effects of the IUIDP include that the government did not provide either compensation (for those who had to sacrifice their land) or reconstruction assistance (for those who had to cut back their property for access routes). Another adverse effect was experienced by tenants who found their rent increased. There was a widely held perception among the residents surveyed that, on balance, the project had been beneficial.
