Oh, don’t worry about a number of requests. We are here to help you! So, feel free to ask.
1) a) Use the Google Favicon Snatcher to check your favicon as seen by Google. Yours seems okay: https://www.google.com/s2/favicons?domain=https://www.kopiteori.id/
b) Check your Google Search Console: Google displays your favicon in its interface, and the Search Console seems to be quicker than the search engine.
c) Of course, this feature completely depends on Google. It takes at least a few days or even weeks for Google to show your favicon in its results pages. The delay seems to depend on the popularity of your site.
The fact that Google crawled your site does not mean that your favicon will be displayed in the next few hours/days.
