Advice on pre booked events/activities in Jakarta June 2025

Hi Jakarta, 

I'm travelling to your city from Australia for a week in early June 2025 6-13th. 
In order to receive free travel insurance through my credit card I need to spend about 2,530,000 Rupiah in Indonesia before leaving Australia. 

I am staying with a friend so don't need to book any accom.

Are there any events or activities or tickets I could purchase online with a visa card before leaving Australia that you would recommend? It can be in as many transactions as long as it adds up to the above amount.

I happy to do/see anything really that you may recommend and am open to any options.
