Wikipedia says it's 15
According to the Indonesian Penal Code article 287, the age of consent in Indonesia is 15 years old. The age of consent is the minimum age at which an individual is considered legally old enough to consent to participation in sexual activity. Individuals aged 14 or younger in Indonesia are not legally able to consent to sexual activity, and such activity may result in prosecution for statutory rape or the equivalent local law.
Even though the age of consent is 15 years old, the offender can only be charged and prosecuted if a legal complaint is lodged to the law enforcement. Exception to this law is when the age of the victim is under 12 years old, or under certain circumstances such as bodily injury or incest.
However, under the Child Protection Act, the age of consent could be raised to 18. The argument used is that sexual acts with a child could result in bodily and mental injury, while the definition of a child is anyone who is under 18 years old. A reported court verdict using the Child Protection Act was done in 2009 against an Australian national.
This one is actually unclear. So which one is right? 18 or 15? There are plenty of prostitutes that trade sex and nobody bother.
I look around at more issues.
What is the Indonesia Age of Consent? The Age of Consent in Indonesia is 16 years old. The age of consent is the minimum age at which an individual is considered legally old enough to consent to participation in sexual activity. Individuals aged 15 or younger in Indonesia are not legally able to consent to sexual activity, and such activity may result in prosecution for statutory rape or the equivalent local law.
Indonesia statutory rape law is violated when an individual has consensual sexual contact with boys under age 19, or girls under age 16. The age of consent for homosexual activity is 18.
This one says 16 years old.
We have a discussion by someone that's confused here
Article 82 of child protection act prohibits
Any person who deliberately inflicts violence or threats of violence, force, deceit, lies, or persuades a child to commit or permit obscene acts, shall be published with a prison sentence of between three and fifteen years [and a fine of between 60 million and 300 million rupiah]
https://www.hukumonline.com/klinik/detail/ulasan/lt5018012dba3d7/bisakah-dipenjara-karena-berhubungan-seks-dengan-pacar this article says having sex with "girlfriend" is legal.
This one says that the age of consent is 15 years old http://sexualrightsdatabase.org/static/country-373.html
It seems that age of consent is 15.
However, there are laws against "persuading" and "economically exploiting" anyone under 18 for sex or lewd acts (that may include petting). I have no idea what counts as persuading and economically exploiting. If someone shop for clothes and buy expensive dinner, does that count as "persuading" or "economically exploiting"
Basically I want to know actual court cases where someone is convicted of lewd act to a girl after 15 years old and what elements are there.
I look for cases around. It seems that in most cases (all cases) there is some "aggravating factors"
For example https://www.jpnn.com/news/mengejutkan-calon-doktor-menyabuli-20-kali?page=2 this case is homosexual
https://www.elshinta.com/news/156194/2018/09/21/polres-pasuruan-bekuk-empat-dari-enam-pelaku-pencabulan-siswi-sma this one involves rape. However, the girls' boyfriend that only pet the girl also got article 82. Article 82 have the same punishment with article 81. So it seems like raping a girl has the same penalty with con-sensually groping her.
It seems that the law is against non consensual act against those under 18. For example, say a guy grope a girl non consensually.
However, article 76e of Indonesian law no 35/2014 have phrases
Setiap Orang dilarang melakukan Kekerasan atau ancaman Kekerasan,
memaksa, melakukan tipu muslihat,melakukanserangkaian kebohongan, atau membujuk Anak untuk melakukan atau membiarkan dilakukan perbuatan cabul
Anyone is disallowed from using violent or threat of violent forcing, or frauding, or doing various fraud, or persuading to do lewd act.
Most of the word, except "persuading" describe non consensual activity. The word persuading refers to consensual activity. That's very strange isn't it?
This link says https://www.hukumonline.com/klinik/detail/ulasan/lt5125d3aaf3911/dapatkah-menjerat-pidana-anak-yang-lakukan-pencabulan that if 2 people are under 18 and they have sex, that is a crime but they cannot be criminalized.
If that is the case, why not just say "Age of consent is 18". That will be much more clear. Why make age of consent to be 15 and then say you cannot persuade anyone under 18 to do lewd act?
