To calculate the quantity of Palm Oil Mill Effluent (POME) produced, you need to
multiply the weight of the palm fruit processed by the yield ratio of 0.5 (or 50%).

The formula would be as follows:

Quantity of POME = Weight of palm nut processed * Yield ratio (50% or 0.5)
For example, if you have processed 10 tons of fresh palm fruit, the calculation
would be:

Quantity of POME = 10 tons * 0.5 = 5 tons

Therefore, in this scenario, processing 10 tons of fresh palm fruit would result in
the production of 5 tons of POME.
