Read the below announcment from Google Adsense team.
We’re glad to announce that Indonesian has just joined the family of AdSense supported languages. Let’s celebrate by raising our hands in a kecak dance, watching a wayang kulit show or cooking traditional Indonesian recipes.
If you have a website in Bahasa Indonesia, you'll now be able to earn money by showing Google AdSense ads. To get started, sign up for an AdSense account. We'll review your application and in the meantime, we recommend you get familiar with the basics of AdSense and our policies.
If you already have an AdSense account, simply implement AdSense on your site in Bahasa Indonesia to start displaying contextually targeted ads.
You can now also implement AdSense for Mobile content on your mobile sites in Bahasa Indonesia. Check out our Help Center to learn how to implement AdSense on a mobile site.
Selamat datang di program AdSense!
