Add onion (cut side down) and ginger to pot and cook until well browned, about 5 minutes. Add 6 cloves garlic and roughly chopped scallions and cook, stirring, until lightly browned, about 3 minutes. Return short ribs to pot along with gochujang and doubanjiang. Stir to coat vegetables and beef in spice mixture, then add strained kombu broth and chicken broth, scraping up any browned bits from the bottom of the pot. Bring to a boil, reduce to a bare simmer, cover with the lid slightly cracked, and cook until beef easily separates from the bones, about 4 hours. For best results, allow to cool and transfer to refrigerator overnight.
