THE UTILIZATION OF FERMENTED PALM OIL SLUDGE, METHYONINE, LYSINE AND TRIPTOPHAN ON LAYERS DIET TO REDUCE ENVIRONMENT POLLUTION

The aim of this study was to evaluate the effect of feeding fermented palm oil sludge and critical amino acid
(CAA); methyonine, lysine and tryptophan supplementation on diet to reduce environment pollution. The
research design used was completely randomized design with 4 treatment groups. The treatments were P0:
control diet, P1: 50% CAA on diet, P2: 75% CAA on diet, P3: 100% CAA on diet. Parameters measured were
nitrogen, amoniac, sulfide, phosphor, Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand
(COD) feces. The results showed that there was a highly significant effect of feeding fermented palm oil sludge
on nitrogen, ammoniac and sulfide in feces (P<0.01) and phosphor (P<0.05). However, the treatment
insignificantly affected BOD in feces. In contrast, the COD was very significantly affected by the treatment
(P<0.01). In conclusion, feeding fermented palm oil sludge with additional of CAA may have effect to reduce
nitrogen, ammoniac, sulfide, phosphor and COD on layer feces; which resulted in a decrease on environment
pollution. The best treatment was the diet contains 100% fermented palm oil sludge.
