Abstract:
A study on the dynamics of the Change Dynamics of the Maluka Watershed
Boundary Map in South Kalimantan Province, which aims to analyze the Maluka Watershed
Boundary is a large-scale approach, analyzing the dynamics of changes in some watershed
characteristics (morphological and morphometric aspects) and conducting a policy direction
towards the Compilation of the Maluka Watershed Boundary Watershed. The results of the
Maluka watershed boundary scale of 1:50.000 there are changes and improvements in
watershed boundaries in the downstream watershed due to river drainage, dredging, river
displacement caused by human activities, new watersheds formed and SRTM level 30 x 30 m
resolution, line repair and correction coastal and river networks and optical remote sensing.
Morphometric and morphologic characteristics of Watersheds Significant changes in watershed
area and administration area (reduced by 4.678 Ha or 5,3%). Other properties did not change
significantly (Hydrologic DAS: 2 sub-watersheds, namely the Bati-Bati sub-watershed and
Banyuhirang sub-watersheds), (Watershed shape: elongated (Rc <0,5)), (Slope class: flat
90,24%, steep and rather steep 2,14%), (Altitude/Elevation) Watershed: 2 masl to 50 masl
81,71%, above 300 masl 4,37%), (Watershed orientation: heading east to west in a straight
direction, middle watershed symmetrical ballooning), (flow density, index value: 1,09 medium
category) and (DAS flow pattern: Dendritic). Policy recommendations are suggested to
synchronize the implementation of UU No. 23 Tahun 2014 and UU No. 37 Tahun 2014 in terms
of carrying out the mandate of PP. 37 Tahun 2012, namely the implementation of the
management of watershed management in the context of conservation of land, water in the
ecosystem/watershed unit by giving the mandate to assist the task of sub-affairs management
of watershed management from the provincial government to the district / city government.
