IMPACT OF FOREST FIRE INDUCED HAZE ON OIL EXTRACTION RATE (OER) IN CENTRAL KALIMANTAN PROVINCE
Mathews J, Ardiyanto A

Abstract
Dense haze, caused by the smoke from peat fire in Central Kalimantan, Indonesia from September to October 2015, resulted in low oil extraction rates (OER) in the palm oil mills. The reduced total sunshine hours due to haze affected the OER four weeks after, even though the crop was harvested at the minimum harvesting standard of 5 loose fruits on the ground. The haze resulted in low OER in October and November 2015. Bunch sampling and analysis indicated that the inner fruits were pale yellowish in colour with correspondingly low oil content. The possible emission of ethylene gas from the burning forest and its role in the early abscission of fruits of the fresh fruit bunches (FFB) are discussed in this paper.
