ABSTRACT
The purpose of this study was to determine the effect of compost sludge waste from the Palm Oil Mill rice productivity using SRI modifications. The rice variety used is Batang Piaman. This study used a Completely Randomized Design (CRD) with five treatment sludge compost doses, namely 0 t.ha-1 (control), 10 t.ha-1, 15 t.ha-1, 20 t.ha-1 and 25 t.ha-1 repeated three times. The results showed that the compost sludge of Palm Oil Head Factory significantly affected the parameters of observing plant growth rate, net assimilation rate, maximum number of tillers, number of productive tillers, and weight of milled unhusked rice. The best dose of sludge fertilizer for rice production is the 20 t.ha-1 sludge compost dose which can increase rice productivity by approximately 90% compared to the productivity in the Batang Piaman Vaietas description.
