Stay Permit Expiry date

From https://www.imigrasi.go.id/wna/daftar-visa-indonesia/B1 - free translation
B1 Tourist Visit Visa

...The B1 Visa is a Visa on Arrival ... for a single entry ... with an initial stay of a maximum of 30 days, counted from the date of arrival. This Stay Permit can be extended once...

https://evisa.imigrasi.go.id/web/visa-selection

Type of Visa B1 - 30 Days
1. Stay
Up to 30 days (extendable for another 30 days) ...

-----------------------------------

So from the above information I suggest :

1) Check the exact day the extension was issued (this because it can be extended before the first 30 days finish) ;

2) Including the day the extension was issued , she has 30 permitted stay days . So the day 1 is the day when the VOA's 'Visit Stay Permit' extension was issued . Not after the day 30 , she should leave .
If she leaves on day 31 , she will probably have to pay 1 day overstay fine .

In the old days you had to count it yourself. Now it actually says on the visa. The evoa. And the B1. So no mistake. Usually. Lol

So you suggest I reply to the young lady in question and say 'Doesn't really matter, they'll only pull you aside at the airport and fine you a million, you'll probably not miss your flight or anything, no big deal, a million is fine for you yes ?'.

That's what you'd say to your daughter perhaps ? - no, I suspect you'd want to be a little more helpful than that, answer the question she asked so she can get as long as she can here and still leave the country without paying extra or worrying about having hassle on departure.

You might be an experienced foreign traveller and have no fear of men in uniforms taking you aside, but not everyone is like you, and not everyone thinks 60 bucks is nothing.

If she is not able to handle that, she should not be "backpacking" to start with......
