The solution to make it easy to book a meeting place is in the form of the Meeting Room Booking application which is the research theme of this publication's text. This information system design method uses the SDLC (System Development Life Cycle) method in which there are requirements analysis stages, system design, system coding, system testing, and analysis. The feature given by the user is that the user can book a meeting place based on time, the desired place and the number of meeting attendees' capacity that can be done without the user having to reserve a location directly and get information on the availability of places that can still be used for meetings. Admin is given a website admin dashboard that is used to monitor incoming orders. By doing this research can facilitate a number of employees who want to book a meeting place quickly when an unexpected time or from a long distance without having to review the location of the meeting by visiting one by one location but only by looking at a review of places through the application. They can immediately determine the place as desired and determine the accommodating room with the number of meeting participants.

    EXPLORING THE RELATIONSHIP BETWEEN CLOUD COMPUTING AND BLOCKCHAIN: The Integration of Both Technologies and Its Impact on Ethical Problem
    (International Journal of Psychosocial Rehabilitation, Vol.24, Issue 02, 2020) Padmanegara, Oliver Hasan; Sutisna M.N, Deden; Oktaviani, Desy; Genia, Gita; Yuliani, Reva
    Cloud computing is a form of technology that has the ability to reduce costs in a business process. However, cloud computing poses ethical problem which is the consumers’ right to privacy and thus it leads to ethical dilemma that involves the provider, consumer, and government. Another form of technology that recently emerged and has the capability of improving operating activity is blockchain. Blockchain is a form of distributed ledger that has the capability to record transaction in a highly secure manner. There are many studies that investigate the impact of cloud computing as well as blockchain on enterprise-level users. However, there is a limited amount of study that investigate the link between cloud computing and blockchain and its impact on privacy issue. Therefore, this research investigates the relationship between cloud computing and blockchain as well as its impact on privacy issue by exploring the collected secondary data. The research finds that cloud computing could support the implementation of blockchain by nullifying the challenges that blockchain faces in terms of cost, scalability and performance. This is indicated by the emergence of blockchain as a service (BaaS). The research also finds that blockchain could improve cloud computing security issues in the future. Finally, the research finds that the future integration of both technologies could mitigate the cloud computing ethical problem which is the breach of consumers’ privacy.
