Plane crash landed in Borneo jungle in 1983.
That registration looks like
PK-DCR to me. It's a little bit blurry, but especially if you zoom in, it's fairly readable.
A quick web search for that registration and "airplane" brings me Wikipedia's page on Deraya Air Taxi, which indicates that
On November 1982, Indonesian Aerospace 212-100 PK-DCR of Deraya Air Taxi and PT Pupuk Kaltim was damaged when it approaching Bontang. No fatalities in this accident.
The 212-100 brings us to the CASA C-212 Aviocar.
Looking at the pictures on Wikipedia, it's pretty close, so that's probably it. Note the pretty distinctive tail section, and the relative dimensions:

The aircraft was a CASA 212 registered PK-DCR which crashed on November 8th 1982, near Bontang, East Kalimantan
