Abstract:
Evaluation of environment change pasca oil palm in the tropical peat lands
need data about precisely and comprehensive understanding of lands and socioeconomics.
The study was done in the Riau District were conducted infour months.
Thefield survey was carried out on land unit. The lands were evaluated by maximum
Iimiting factors and the socio-economic were calculated by Multi-Dimensional
Scaling. Development of oil palm existing in the peatland not yet followed the soil
conservation, so that giving influence to change oflands environment: (l) Saturation
at all location > 4 mS, with full marks there was Bengkalis 107,32 mS; (2) Land
subsidence > 6 cm year' espectally Rokan Hitir have l 8 cm year' ; and (3) Change of
ground water exceeding valuefloatfor oil palm (60 cm), highest value there was Siak
30-95 cm. Level continue oil palm plantation in peat landsfor the ecologt dimension
showed index value 47,35ok (less have continuation), with ecologtfactor having an
effect: anangement water level, prevention of burning land, usage of
amelioran/fertilizatton, and specific adjusment of site technologt. Level continue oil
palm plantation in peat lands for social dimensio;n showed index value 55,65%
(enough have continuation), with social factor having an effect: community
emp-owerment, policy synchronization, solving of sosio-conflkt, and weak of law
straightening. Level continue oil palm plantation in peat lands for economic
dimension showed index value 68,62% (enough have continuation), with economic
factor havingan effect: capital structure, price ofTBS, andproduction equipments.
