Analisis Potensi Tanaman Hutan Industri Sebagai Agen Fitoremediasi Cemaran Logam Berat Asal Abu Terbang

Analysis of industrial forest plants form of Acacia crassicarpa and Acacia
mangium can as a phytoremediation agent in absorbing heavy metals in fly ash from
coal burning boilers which are used as ameliorants to improve peat soil. Giving fly
ash to peat soils that pollute the soil and disturb the soil ecosystem. The purpose of
this study to analyze the ability of A. crassicarpa and A. mangium to reduce heavy
metal content in soil contaminated by fly ash, to estimate economic valuation and
analyzing the adaptability of plants to the presence of heavy metals in their growth
media. Experiments using factorial and placement using RAL. The increase in the
concentration of fly ash given is 0 ppm, 2000 ppm, 4000 ppm and 6000 ppm by
looking at the absorption ability of the metals Co, Cd and Pb contained in fly ash. The
results of the analysis of the ability of industrial forest plants to absorb heavy metals
showed that A. crassicarpa was more effective in absorbing Pb metal as seen from the
relatively high accumulation of Pb in its biomass, the absorption rate of Pb metal
which was quite high and the efficient absorption of Pb metal which was quite
effective. Meanwhile A. mangium is more effective in absorbing Co metal which can
be seen from the metal accumulation which is quite high in its biomass, the absorption
rate of metal Co is quite high and the effectiveness of metal Co is quite effective.
Meanwhile, Cd metal showed no significant difference between the two types of
industrial forest plantations. The highest BAC (Biological Accumulation Coefficient)
value was found in A. crassicarpa in absorbing Pb metal which was 3.55 mg / Kg. The
value of phytoremediation ability was found in A. mangium, the largest at Rp. 7.99, - /
seed / 3 months for Pb metal while the largest A. crassicarpa was at Rp. 16.76, - / seed
/ 3 months for Pb. This valuation value is expected to continue to increase along with
the development of plant biomass. The adaptation of A. mangium and A. crassicarpa
was able to adapt well to the presence of heavy metals as seen from the morphological
conditions of plants.
