The challenge gave a screenshot of a conversation between the author and the laundry shop. That chat showed three useful facts: there was a fire at the central shop, the fire happened on 21 April 2026, and the author used a branch shop rather than the central shop.

A web search for a laundry fire on that date led to Jalan Radio Dalam Raya, Gandaria Utara, Kebayoran Baru, Jakarta Selatan. Google Maps showed the burned business name as Laundry Perkilo Premium.

Searching Laundry Perkilo Premium on Google Maps showed many branches around Jakarta. The next check was each branch’s reviews, because the hint said to validate the branch by checking reviews and then look for a nearby hotel with another review.

Hint: validasi cabangnya dengan cek review. setelahnya, ada hotel didekat cabang tersebut yang ada review juga

The matching branch was Laundry Perkilo Premium Rasuna. Its Google Maps review contained the first flag part, pareh. For the flag format, the laundry name became perkilopremiumrasuna.

After the branch was identified, the area around it showed Rasuna Icon Hotel nearby. The challenge format required the hotel name in lowercase with no spaces, so this became rasunaicon.

The hotel reviews contained the second flag part, tapiDiganti, which confirmed the hotel and completed the flag components.
