| dc.description.abstract | This research aims to analyze the pattern of changes in the function of paddy
fields to non-paddy fields in North Labuhanbatu Regency and its suitability on the
Regional Spatial Plan of North Labuhanbatu Regency between 2017 and 2021.
Geographic Information System (GIS) as a spatial analysis tool is used to
compare land cover from satellite imagery in 2017 with 2021 so that the results of
the change in the function of paddy fields to non-paddy fields in 2017-2021 are in
accordance with the RTRW of North Labuhanbatu Regency in 2015-2035.
The results showed that there were 3 (three) patterns of changing the function of
paddy fields into non-paddy fields. that are (1) Paddy fields - Built-up Land
covering an area of 111.22 ha, (2) Paddy fields - Open land covering an area of
86.08 ha, and (3) Paddy fields – Non-Paddy fields Vegetation covering an area of
2,795.58 ha. Changes in the function of paddy fields to non-paddy fields in 2017-
2021 which are in accordance with the RTRW of North Labuhanbatu Regency in
2015-2035 are 3,034.47 ha, and those that are not suitable are 10,811.46 ha. The
existing paddy fields in 2021 which are in accordance with the RTRW direction
are 1,806.03 ha (18.44%), and those that are not suitable are 4,566.89 ha
(46.62%) and the transition area is 4,480.14 ha (45.74%).
In a period of 4 (four) years, the area of paddy fields in 2017 - 2021 has
decreased by 2,992.88 ha (21,62%) with the pattern of changing paddy fields into
non-paddy fields vegetation the most occurring. The suitability of the paddy field
area with the RTRW produces very significant results, namely larger areas that
are not suitable than those that are suitable, due to the existence of a transition
area where most of the largest area of suitable areas is located here. This has the
potential for a very rapid transfer of function if it continues to be ignored and will
affect the harvested area of lowland paddy and the productivity of lowland paddy
which will continue to decrease, thereby disrupting food security in North
Labuhanbatu Regency. | en_US |
