PENGKAYAAN TANAH BEKAS TAMBANG EMAS DENGAN PENAMBAHAN LUMPUR IPAM SEBAGAI MEDIA PERTUMBUHAN SAWI (BRASSICA JUNCEA L.)
ABSTRACT: Soil of former gold
mine requires soil quality improvement through increasing organic matter
compound that may be sourced from the sludge of water treatment plant (IPAM).
IPAM sludge which a by-product of water treatment from Kapuas river contains
humic substance. The research aimed to discover the effects of former gold mine
soil improved by IPAM sludge addition on mustard (Brassica juncea L.) growth.
The research was conducted from August to October 2013. The research used
Completely Randomized Design which consists of five planting media combination
with five replications following replacement series method. The planting media
combinations used are : Treatment A (0 % IPAM sludge : 100% former gold mine
soil), Treatment B (20 % IPAM sludge : 80% former gold mine soil), Treatment C
(40 % IPAM sludge : 60% former gold mine soil), Treatment D (60 % IPAM sludge :
40% former gold mine soil) and Treatment E (80 % IPAM sludge : 20% former gold
mine soil). The results showed that the combination of 60% IPAM sludge: 40%
former gold mine soil media significantly affecting the growth parameters of
mustard, which are: up to 397.80 cm2 leaves area growth, 35.12 g wet mass and
0.42 g dry mass.
