Do I need a visa to go to Kuala Lumpur for one day, then go to Bali and come back in Kuala Lumpur for another day?

You don't need a visa, but you need an air ticket from a third country, which is exempt for 5 days, counting the arrival date and departure date.

AirAsia's plane, as everyone gets off the plane, will go to a hall, pick up the form at the small window on the left (near the toilet), fill it out, hold the passport and the ticket to a third country within five days, and it will be examined and stamped soon. If there are not many people, 10 minutes is no problem.

After completing the transit visa, you can enter the customs.

The same is true when you come back from a third country. Do it again.

It should be noted that although the transit visa permit card is free, it will be fined if it is lost. . This is to be presented to the customs when leaving Kuala Lumpur for a third country.

Bali is landing visa. Just pay in the airport lobby when you get off the plane. Also, you should take good care of the entry card. You need it when you leave this country.

In short, all documents of Kuala Lumpur transit visa and Bali visa should be kept well.

Bali is beautiful, especially Uluwatu. I hope you have a pleasant trip. .
