The result shows that in testing process the ANN can recognise PD pattern with correct responses about 100% using training data set. For untrained data set or tested data set,

Partial discharges (PDs) are small electrical sparks resulting from the electrical breakdown that occur when void exist within on the surface or in other highly non-uniform

recommendations of the conference – that the expansion of sustainable palm oil production must not take place in concessions that should be frozen, according to the BPK-RI

Increased returns from a strong global demand for vegetable oils are expected to encourage investment in the palm oil industry leading to continued growth over the medium term,

Figure 7 The patterns of biogas production from POME at different fermentation temperatures A fermentation temperature of 55oC produced biogas with a methane content that was higher

POME samples were taken daily from a series of treatment ponds namely a raw effluent pond, an acidification pond, an anaerobic pond, an aerobic pond and also the final discharge in KKS
