TKPM Gajah X Mati: TWILIGHT AND THE NEW DAWN ON THE HILL OF TKPM BUKIT PERAK

New Episod . The hill of TKPM Bukit Perak is being planted with Jack Fruit.

Kereta Yang Memecah Rekod Mendaki Kemuncak Gunung Brincang Dalam Tahun 2005

DTO di Kemuncak Bukit Perak:

DTO the Commando!! Siapa Yang Tahu Di Zaman Komunis Berkeliaran Di Hutan Pedu?

The Last Mangga of Bukit Perak !!!

DTO Nasihatkan Buat Terrace dan Cover Crop.. Jangan Ulang Kesilapan Zaman Dato N

The manggo project started years earlier meet a complicated ending. Now the jackfruit is new the new dawn.

Terracess Pemulaan Yang Baik...

Reclearing of the hill and repairing of the terraces.

Rain Drop points visbile on the soil surface after simulation

Culculation of relative K :

hujan dari simulator =18mmX8replicates =144mm
Jumlah sediment dari lapan simulasi =25.7721gm
K relative=25.772/144= 0.1789gm/mm hujan>>>>

CONTOH >> Nilai K Relatif Bagi Siri Musang Yang

= 0.179 gm/mm hujan

K=0.179/727+0.00215 =0.0024

K HANYA ini di gunakan untuk RUSLE Dimana R=Annual rainfall in mm

RUSLE MALAYSIA STUDY OF EROSION ON THE MAP

A=RKLSCP

A= Soil Loss per anum ton/hac
R= Annual rainfall in mm
K= Erosivity Factor according to soil series value 0.00***
L=Length of Slope on the map(1;25,000 in cm
S= Slope Terrain factor :Average of Terrain Class C1=1,C2=4,C3=9,C4=16,C5=22.5
C= Crop factor .For bare soils C=1
P= Conservation Measure . Bare soil P=1

Example: Bare soil (clear land) with steep slope C5 (20degrees-25 degrees)

Cuculation of LS of 10cm slope length on 1:25,000 map

LS= Length of slope on mapXSlope /terrain class factor
=10cmX C5= 10cmX22.5

A=RK X 10cmX 22.5X 1X 1
= 3500mmX 0.002 X 10 X 22.5

=1575 ton per hac per year

Erosion per month approximately 150-200 ton according to rain intensity for the month. So soil cover,mulch and wettle must be established quickly to control erosion.

N.B
10cm on the map 1;25000 =10cmX25000=250,000cm=2500 meters
