It is my pleasure to give a keynote speech at International Conference on Recent Challenges in Engineering and Technology (ICRCET) 2023 in Jakarta which is organized by Institute for Engineering Research and Publication (IFERP). The use of electric vehicles has been promoted by various countries around the world as a viable way to reduce our dependency on fossil fuels. However, one big problem related to the use of electric vehicles is their slow charging time. Thus, fuel cell electric vehicles (FCEVs) which are powered by hydrogen has emerged as another promising option. Yet, the performance of FCEVs is strongly affected by an efficient hydrogen storage system. Therefore, I will be presenting about the importance of hydrogen energy in Indonesia and how to use 2D materials to reduce the cost of FCEVs and to enhance the safety of hydrogen storage systems. Best wishes for all participants of this intriguing conference and I look forward to meeting you all! Special thanks also dedicated to IFERP.

I am delighted to be a part of the 11 th International Conference On Recent Challenges In Engineering and Technology (ICRCET-23), and I am looking forward to it which is to be held in Jakarta on  16 th and 17 th June  2023, organized by Institute For Engineering Research and Publication (IFERP). For good ideas and true innovation, you need human interaction, conflict, argument, debate. In this age of digitization, the most essential components for businesses is to adopt digital marketing, and smart technology, that improve environmental sustainability. This conference will, definitely, be helpful to the researchers, and academics to get the theoretical and practical details pertinent to the topic of “Value Creation in the Digital Age Through Digital Marketing.” I wholeheartedly appeal to all participants to move forward to conduct further advanced research in Sustainable Technology. I am thankful to the organizers for their great efforts in making this scientific event remarkable, stimulating, and successful. My thanks also go to all the participants. Wishing you all the best.
