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 largescale 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.
