T The development of information and communication technology is so rapid and not everyone understands how to use information and communication technology properly and correctly. Along with the development of technology, threats and disturbances arise that interfere and even damage the work system of a company or organization. The data center has become an important part of an organization. Organizational data is retrieved, processed, and stored back in the data center. Data center security is something that must be considered, one of which is the physical security of the data center room. The Bureau of Planning and Information Systems Administration (BARENSIF) as the institution that is the center of all information systems at Trisakti University must ensure that data and information are presented accurately and without interference. The physical security of the data center room in the Planning and Information System Administration Bureau (BARENSIF) is still very vulnerable, and is far from the standardization issued by TIA-942. The research carried out is to analyze the assets in the data center room and the physical security system used is adjusted to the TIA-942 standard in the data center room of the Planning and Information System Administration (BARENSIF). The result of this final project is the design of the physical security design of the data center room at the Administrative Bureau of Planning and Information Systems (BARENSIF) Trisakti University. With the addition of this physical security device, it is hoped that all activities within the Planning and Information System Administration Bureau (BARENSIF) can run well and be beneficial for the organization.
