One idea could be to get your dad a personalized Jungkook poster or album. You could also look into buying him concert tickets (if available) or a piece of Jungkook merchandise such as a t-shirt or hoodie. Another idea could be to make a Jungkook themed gift basket filled with some of your dad's favorite snacks or drinks, along with some Jungkook photos or albums. You could also consider booking a Korean BBQ restaurant for the two of you to enjoy together or taking a Korean cooking class to learn how to make some of your dad's favorite Korean dishes.
Or you can get him a star map with the date when he welcomed you in this world.
