Abstract

The use of large-scale information technology in office environments with dense buildings such as universities can trigger high electricity consumption. The high consumption of electrical energy will have an impact on the number of costs incurred for infrastructure and the carbon emissions produced will have a negative impact on the environment. Based on these problems, the Green Computing concept is used as a solution to manage the use of electrical energy that is environmentally friendly. Green Computing is a concept that focuses on the greening of the environment for the use, preparation and recycling of information technology (IT) devices effectively and efficiently. In achieving Green Computing conditions, two interconnected approaches are needed, namely information technology user behavior and infrastructure conditions. In the condition of user behavior, researchers used the Theory of Planned Behavior and Theory of Reason Action to analyze the readiness of user behavior. Whereas in infrastructure conditions, researchers used the technique of calculating Power Usage Effectiveness and Data Center Infrastructure Efficiency to measure the readiness of infrastructure conditions. The study was conducted using a qualitative approach.The case study research design used in this study is because researchers want to understand more deeply related to the perspective of infrastructure conditions and user behavior in the case studies taken.
