Limited productivity and degraded performance confronted
by the palm oil smallholders are caused by the lack of
knowledge and experience for proper costing of fertilizer
application and labor. As such, optimizing the application
rate of the fertilizer indirectly helps to obtain high yields
and profits per unit area of the palm oil plantation. However,
these issues are often disregarded [3]. Basically, minor or
nonexistent information and experiences on suitable fertilizer
application to the palm oil cultivation triggered by the remotegeographical location and insignificant technological infrastructure.
As such, palm oil smallholders disconnected from
knowledgeable people regarding the fertilizer and exposure
to better crop management efficiency and agronomic practices
were trivial [4]. Additionally, support from government
agencies, such as RISDA and MPOA, have faced with
difficulties in reaching palm oil smallholders in a whole
country continuously and simultaneously
