The era of data disruption and the Industrial Revolution (IR) 4.0 provides an increasingly strong challenge for the government to prepare and optimize all its resources so that they are able to compete. Likewise, local governments are aggressively making real efforts to meet the challenges of IR 4.0. One of the central government policies that continues to be passed down to regional governments is the policy regarding the development of on line one-stop services (on line one-stop government), which are integrated through an open government format. Local governments of Bogor City and Bogor District are two of the local governments that have implemented on line one-stop government and open government. The main objective of this research is to conduct a comparative study on the implementation of on line one-stop government and open government. The method used is referring to open government maturity model (OGMM), and the case study is in the City and District of Bogor, West Java Province, Indonesia. The five basic principles of one-stop on line government have been implemented, although they have not yet fully succeeded in providing optimal services for the community. The basic principles referred to include downsizing, managerial, decentralization, debureaucratization and privatization processes. Bogor City already has a one-stop on line service, and the document transaction process until the application status has been well managed. Bogor District has completed the one-stop on line service with a video tutorial process, but document transactions are still done manually. The development of continuous studies to increase the value of data through the application of the Big Data concept to the open government system of Bogor City and District is very potential to be carried out.
