Abstract: This research conducted on the Catur
sub-watershed-Kare District with the area of 190.85 km
2
. The
study location is oriented on the Kare District-Madiun Regency
which included four villages such as the Kepel, Kuwiran, Kare,
and the Bodag. This research intended to study the value of
erosion and sedimentation for analyzing the Erosion Danger
Level (TBE). Result of the TBE analysis can be used as the base
on determining the Village Soil Conservation Plan (RKTD) in the
Kare District. The pparameters of the Catur sub-watershed
condition during the 10 years will be processed by using the
AVSWAT 2000 for producing the value of erosian and
sedimentation on the Catur sub-watershed. Result shows that the
Erosion Danger Level (TBE) in the Bodag village is in the level of
light to heavy (21.89%), however, in the Kuwiran village is in the
level of light to heavy (14.46%), in the Kepel village is in the level
of light to moderate (22.23%), and in the Kare village is in the
level of light to moderate (41.31%). The Village Land
Conservation Plan that is applied in the Kare sub-district are
conservation by the vegetative and mechanical method, however,
in the Bodag village and Kuwiran by the vegetative conservation
method with the regulation of land use, in the Kare village by the
vegetative and mechanical conservation method with the
regulation of land use and by building the two check dams, and in
the Kepel village by the mechanical conservation method with
building a check dam. The result is hoped as the reference for the
recovery and management of the sustainable soil conservation.

I. INTRODUCTION
The wealth of international reports and websites shows that
there is no shortage of the interesting cases and good practices
from the various sources. The organization and the
individuals are often quite willing to the showcase and share
their experiences in the international forum.

In fact, the reporting experiences with the water policy and
management arrangements at the international platforms can
be considered the recognition of those experiences as the
hallmarks of an innovative spirit and of being at being at the
forefront of the water governance [1][2]. However, the land
use planning is significant for the watershed conservation and
management [3]. The most land use restriction strategies
assume that the land use activities close to the watershed
outlet must have the large impacts on the downstream
environments. However, the watershed characteristics usually
vary in the space; land use restrictions should depend on the
multiple criteria other than the watershed vulnerability index
on the distances from the subdivisions to the outlet. Therefore
some analysis has to consider the geographical and the
meteorological characteristics of the subdivisions in the
watershed. The soil property, surface cover, land-use
conditions, and the topography can influence the hydrologic
responses and the pollutant transport in a watershed [4][5]..
The riverbank erosion is a complex phenomenon
resulting from the various factors which affect the balance of
ecosystems. It is also important from the geomorphological
aspect as it also induces the changes in the river channel
course and in the development of the floodplain [6][7]. The
mass-failure processes constitute a significant source of the
sediment in the disturbed streams, which occur due to a
combination of the hydraulic and geotechnical processes that
undercut the bank toes and cause the bank collapse [8]. The
riverbank erosion is a natural geomorphologic process that
affects the fluvial environment in many aspects: physical,
ecological and socio-economical. It is the result of a complex
interaction between the channel hydraulic conditions and the
physical characteristics. The Soil Conservation Service
estimates that less than half the new land is being farmed with
adequate erosion control and some topsoil was lost from the
added area. This sudden new expansion of the land under
cultivation is but one of many growing threats to the earth's
natural environment that conservationists fear could, have
far‐reaching consequences to step up the food production.
The Madiun River sub-watershed is located in the
Madiun Regency, East Java Province of Indonesia, The
length of Madiun River is ± 28 km and the area is 3,755 km

.
The high sedimentation in the Madiun River is very
threatening the sustainability of human life there. The society
through their treatment of the land preparing method has
contributed as well as potential to push the occurrence of
natural disaster like the flood and the landslide.
