Did you read the previous post which I have amended as I found the post that I wrote previously and I have included the citation from the regulation ...
I confess that I didn't read the part you talk about the Regulation , this because I asked about the Law (which is more relevant) .
But as you insist to argue referring to this Regulation , ok , lets do it :
As far as I understand (but I am not a lawyer) from the Regulation below (that you referred) there are 2 ways to lose the Indonesian citizenship : by the person's own decision (automatic , does not depend on the Indonesian President) , or by request to the Indonesian President .
So , it seems to me that you misunderstood the Regulation when you said (in your post nos.11 & 21) : "... It's important to remember that
only the President of Indonesia has the authority to officially declare someone has lost their Indonesian citizenship, no one else.
So unless you have formally renounced your Indonesian citizenship and declared by the president, it is still a grey area whether you have lost your Indonesian citizen ..." .

PP no.2 Year 2007 - free translation
Article 31
(1) An Indonesian citizen
automatically loses his or her citizenship due to:
a. acquiring another citizenship of his or her own free will;
.....
g. holding a passport or a document representing a passport from a foreign country or a document that can be interpreted as valid citizenship from another country in his or her name; or
...
(2) Indonesian citizens shall be declared to have lost their citizenship
by the President upon their own request if the person concerned is 18 years of age or is married, resides abroad, and by being declared to have lost their citizenship of the Republic of Indonesia, they do not become stateless.
Article 35
(1) An application for loss of citizenship as
referred to in Article 31 paragraph (2) is submitted in writing by the person concerned to the President through the Minister.
.....
Article 38
(1) The President shall issue a decision regarding the loss of Indonesian citizenship.
.....
Poster's Note : Although Article 38 does not clearly state , to me it makes sense to think that it refers to the case where the person request the citizenship loss to the President , as Articles 35, 36, and 37 clearly state to relate to this case .
