research by Lembaga Penelitian Universitas Sumatera Utara, the last record refered to No. 01 –<br />
03/H5.2.3.1/PPM/K5/2011 dated on 07.01.2011. The test result of BOD range of the applied POME<br />
in three ponds are between 1,264 – 1,516 mg/l, still below the maximum standard 5,000 mg/l as<br />
required by “PerMenLH No.29/2009” The application of EFB in Langga Payung Estate in Division<br />
area II, IV, V and VI with the dosage 30 t/ha. Fertilizing program developed by SMARTRI covers time<br />

Compliance Status : Full..<br />
Criterion 4.3<br />
Practices minimise and control erosion and degradation of soils<br />
PTTN has soil maps for each estate (Langga Payung Estate, Paya Baung Estate, and Normark<br />
Estate) which categorize the classes of land suitability based on parameters of slope, texture and soil<br />
limiting factors. There are no fragile or problem soils being classified on all the 3 soil maps.<br />
PTTN has established management strategy to minimize and control erosion and degradation of soils<br />
by planting Legume Cover Crops, terracing on undulating to steep areas, pruning and frond stacking<br />
besides having routine road maintenance program. Roadmaintenance is carried out bysandstone<br />
(sirtu) gravelling to make the road surface hard and compact.<br />
PTTN established procedure for land preparation for replanting, however , it was found during the<br />
field visit that the replanting area in Division 1 (LPYE11B21) with slope 16 - 40 % was not<br />
appropriately covered by Muccuna brachteata.<br />
A Minor non-compliance was issued. (See NCR T-02.07/2011)<br />
Compliance Status : Not Compliant<br />
