Internet of Things (IoT) is a concept that utilizes internet network connectivity for a unified system communication. Analysis conducted on the keyword "Internet of Things" by using Google Trends shows trends up from mid 2013 to 2020. IoT will be a part of human culture which is implemented in all sectors of life. The corona virus pandemic is like a blessing in disguise in terms of the adoption and intervention of technology in all settings of human life. This is because during the Covid-19 pandemic, technology was present to be a solution and provide efficiency. This paper was prepared with the aim of completing a study of the application and adoption of information technology, specifically the field of the Internet of Things (IoT) in adaptation to New Normal life. To achieve the goal, this paper is divided into 3 parts, namely the IoT concept and vision section, the existing IoT implementation section based on the physical setting or place and the IoT solution section for New Normal adaptation after the co-19 pandemic in Indonesia. Based on the analysis and discussion, it can be concluded that experts and government are able to react quickly and appropriately in implementing technology (especially IoT) in Indonesia. However, it is still ineffectiveness and inefficiency, because each government unit’s builds its own system. Next, Indonesian government needs to think about and do is to integrate the system. So, it will be able to produce an integrated information that can be used by all elements of operations in all government unit’s that need it.

The Decision Support System (DSS) is implemented by CV. IKS assists the director as a Decision Maker in determining the location of housing developments. In the case of determining the location of the subsidized housing project that was carried out in 2020, the DSS developed with two methods, namely DSS1 with the AHP – WP method and DSS2 with the AHP – SAW method, gives different outputs. The purpose of this paper is to conduct a sensitivity test to determine the MADM method most suitable for completing the locating determination of subsidized housing projects in CV. IKS. The sensitivity test method was chosen because this method can detect every ranking change in each MADM method. The more sensitive the value obtained from the change in ranking suggests the MADM method is the best in displaying the order of the ranked alternatives. It can be seen from the sensitivity test results that the change value of the AHP-WP method is 3.178%, and the change value of the AHP-SAW method is -19.274%. It concluded that the AHP-WP method was considered to be the most relevant in addressing the problem of determining the location of housing developments in the CV.
