EVALUASI KESESUAIAN LAHAN UNTUK TANAMAN KOPI DAN KARET DI DAERAH ALIRAN SUNGAI JAMBANGAN KABUPATEN KARANGANYAR TAHUN 2011
ABSTRACT: The research is
aimed to : (1) to know sub-class level of actual land suitability for coffee
and rubber plant, (2) know sub-class of potential land suitability for coffee
and rubber plant, and (3) know coffee and rubber productivity at Jambangan
Watersheed in Karanganyar Regency.
Based on the result of the research it can concluded as follows: (1)
there are 9 subclass actual land suitability for coffe plant, those are : S2
w,r,f,n,s/m,e (0,51%), S3n(7,59%), S3r,n(5,24%), N1r(12,84%), N1r,s/m(14,99%),
N1r,e(1,63%), N2r (9,59%), N2s/m (12,45%) and N2s/m,e(0,9%); There are 12
subclass actual land suitability for peanut plant, those are: S3w,n(12,47%),
S3w,r,n(8,61%), S3t,w,n (0,84%), N1r (7,70%), N1r,e(1,63%), N1r,s/m (20,77%)
,N2s/m(0,66%), N2w (19,79%), N2s/m,e(0,90%), N2w,r(2,51%), N2w,s/m(10.46%), and
N2w,r,s/m(4,90%); (2) Potential land suitability for coffe plant with a medium
management level produced eight land suitability subclass include: S2r,s/m,
S2w,r,f,n, S2w,r,f,n,s/m, S3r,n; S3r,s/m, S3r,n,s/m, S3r,s/m,e and N1s/m;
Potential land suitability for coffe plant with a high management level
prodused nine land suitability subclass include S2s/m, S2w,r,f,n,
S2w,r,f,n,s/m, S3s/m, S3r,n, S3n,s/m, S3 r,s/m, N1s/m and N1r,s/m; Potential
land suitability for rubber plant with medium management level produced 7
subclass suitability include: S2t,w,n, S3r, S3t, S3w,r,n, S3t,w,r,n,s/m,e,
N1s/m, N1r,s/m; and Potential land suitability for rubber plant with a high
management level prodused six land suitability subclass include: S2t,n,
S2w,r,n,s/m, S3t, S3w,r,n, S3t,w,n,s/m and N1s/m.(3) Highest productivity of
coffe plants get on land suitability subclass N1r,s/m which is 896 kgs/Ha/year
and have the lowest productivity of coffe plants get on land suitability
subclass N2s/m is 47 kgs/Ha/year; Highest productivity of Rubber plants get on
land suitability subclass S3w,n which is 2137 Kgs/Ha/year and have the lowest
productivity of rubber plants get on land suitability subclass N2w,s/m is1618
kgs/Ha/year.
