Urbanization is the main issue that altered the environmental condition nowadays. Urbanization means that there are changes in suburban areas to fulfill the function needed in the urban area. Nowadays, urbanization occurred due to the high demand of housing area with lower budget and comfortable environment of living condition. This condition was presented in the Bogor city case. Bogor is one of the oldest cities in Indonesia which is located in the southern part of Jakarta. Due to the increase of population in the capital city and increased of the higher price of housing, people started to looked for place to stay outside the city. Bogor located in the strategic location just close enough for people to commute to Jakarta. The transit city transform into commuting city. People works in Jakarta wanted to live in a more comfortable place of living and cheaper in price than the capital city started to see Bogor as an opportunity. Based on the data obtained by the Central Bureau of Statistics Jakarta in 2015, there are 187.777 total people commuted daily from Bogor to Jakarta. This condition also triggered by the better quality of access in and out Bogor. Mass rapid transportation and highway toll gate create more land cover changes potential to fulfill the high demand of housing. Thus, this research aimed to see the effect of highway toll gate in the land use cover change in Bogor city. Landsat Images was used using the timeseries method started since 1978 (the official year of Jagorawi Toll gate operation) with the 10 years interval time, 1989, 1999, 2009 and 2016. In determining the land use cover change, NDVI method was used which has been widely applied in detecting the greeneries. The result then evaluated using the supervised classification and validated using the Kappa Accuracy test. The result in 2009, showed that there was 56.97 km2 increase in the build area coverage. This was the highest total of increase rate in the build area coverage that detected through supervised classification. In 2009, Bogor has started to increase the quality of access in the northern part of Bogor. More development has been planned to be executed in the Northern Bogor such as Kedung Badak Toll gates, which will resulted in better access into the northern part of Bogor.
