It's a very versatile word that can be used in many situations, similar to "okay" in English. Here are some examples:
* "Baik, saya faham." (Okay, I understand.)
* "Baiklah, saya akan pergi sekarang." (Alright, I'll go now.)
* "Keadaan anda baik?" (Are you okay?)
* "Makanan ini sedap, baik." (This food is delicious, okay.)
"Baik" is a casual word. For a more formal setting, you can use "setuju" which means "agree".
"Setuju" is more formal than "baik", so you would use it in situations where you need to be polite or respectful, such as in a business meeting or when speaking to someone older than you.
For example:
* "Setuju, saya akan membuat laporan ini." (Okay, I will prepare this report.)
* "Setuju, saya bersetuju dengan cadangan itu." (Okay, I agree with the suggestion.)
I hope this helps!
