INCOME OF THE COMMUNITY AND CARRYING CAPACITY ESTIMATION THROUGH INTEGRATION OF BEEF CATTLE AND ELEPHANT GRASS IN THE POST-MINING LAND IN TANJUNG ENIM, SOUTH SUMATRA

Abstrak

This study aimed to investigate of the carrying capacity in post-mining land through the integration
of cattle and elephant grass so that it can generate income for the community in Tanjung Enim, SouthSumatera.
The research method were (1)
a survey method to
the 21
respondents
of
cattle farmers
around
the
post-land
mining, and (2)
the experiment
of
grass planting was
done in
the Faculty
of
Animal Science
UGM
using
polybags
with
soil
from
the post-
mining
land and elephant grass
from
the surroundings,
with
manure as a treatment. The grass has been planted using 15 polybags for 3 treatments of K, P1 and P2, each
treatment were 5 replications with two times harvests, namely 90 days of age and regrowth after 60 days.
The completely randomized design (CRD) with split splot method was used in this experimental design. The
result showed that only the fertilizer variable had a significant effect (p <0.01) on the biomass production
at harvest 1 and regrowth, while the interaction between harvest and repetition group, harvest and fertilizer
had not significant effect. The treatment of P2 on regrowth was resulted in the largest biomass production
of elephant grass, such as 5.355 tonnes DM/ ha /year that is estimated can accommodate of 1.6 AU of cow.
Furthermore, cattle farming could generate a net cash farm income as IDR 942,533.00/AU/year.
