West Kalimantan
In West Kalimantan estates can be far apart, and some are easier to reach by river.

Logistics first, flying second
A spray drone needs spare batteries, a generator and clean mixing water. For remote sites we sort this out early: who supplies the water and where a safe take off point is.
Local rice and swidden fields
Besides palm there are paddies and upland rice. For small scattered plots, mapping first shows whether a drone actually saves money compared with manual work.
