Not knowing what a VPN doesn't exclude you from using one. Many workplaces use VPNs and it's likely that public internet access points (such as libraries, lounges, restaurants and cafes) could be using VPNs too.
Wikipedia says that Indonesia has an internet penetration rate of 50%. It might be reasonable to assume that a low penetration rate means that a significant amount of the internet access is happening in a work place rather than in a residential place. If a significant amount of access is happening at a work place it might also be reasonable to assume that a lot of that access is happening over a VPN.
