Kajian Ekonomi Biokraft Campuran Batang dan Limbah Cabang Mangium pada Berbagai Kondisi Pemasakan Pulp
Abstract: Addition of P.
chrysosporium fungus on chip mixture of mangium trunk and branch before pulping
process could increase the efficiency of chemical used, save energy consumption
and improve the quality of effluent. Before application in the pulp industry,
it should be made sure that biokraft method of mangium trunk and branches
mixture is economically feasible. This study aims to determine the proper
biokraft process applied to the pulp industry. In this study, costs incurred
from biokraft modified cooking methods (chemical reduction, energy reduction
and the combination of chemicals and energy reduction) were calculated,
capitalized and then compared with the cost incurred from conventional kraft
process.The results showed that biokraft method with modifications on energy
reduction was economically feasible to be applied in pulp industry because it
has the smallest CC/ton of pulp (Rp. 50,952,915.15 /ton of pulp) on condition
that an increase of biopulping operating cost is in the range of 5-30%.
