PENGARUH PENGGUNAAN KOMPOS ESEM (Effective System Emultion Microorganism) PADA PERTUMBUHAN Acacia mangium Willd DI HTI PT. FINNANTARA KABUPATEN SINTANG

Abstract

Acacia mangium Willd has  been  developed industrial forest (HTI) in Indonesia.   It uses as raw material for paper, pulp, building construction, furniture, firewood,  container and others.Based on the result by PT . Finnantara, Acacia mangium Willd was age 6 months  still much below the standards of company that is 2.7 m due to low soil fertility , so it is necessary to attempt for the restore fertility of the soil using type of compost is ESEM (Effective Microorganism System Emultion ). The result showed that the plant Acacia mangium Willd treated compost providing value added high average better than control treatmen. The highest value for plant height increment is the T₄ treatment (dose 700gr), which has an average height of 121,4cm as well as having the highest value component P in 216,72 and component N in 0,40. In every  treatment has increased  in diameter trunk was different and  T₀ (control) has greatest in  2,20cm.  Eventhouhg T₀ has a low value of  P componen in 22.44  and N componen in 0,17, but It has been able to increase the diameter of the plants.
