Query: The Classification of Cropping Patterns Based on Regional Climate
  Classification Using Decision Tree Approach   Nowadays, agricultural field is experiencing problems related to climate
change that result in the changing patterns in cropping season, especially for
paddy and coarse grains, pulses roots and Tuber (CGPRT/Palawija) crops. The
cropping patterns of rice and CGPRT crops highly depend on the availability of
rainfall throughout the year. The changing and shifting of the rainy season
result in the changing cropping seasons. It is important to find out the
cropping patterns of paddy and CGPRT crops based on monthly rainfall pattern in
every area. The Oldeman's method which is usually used in the classification of
of cropping patterns of paddy and CGPRT crops is considered less able to
determine the cropping patterns because it requires to see the rainfall data
throughout the year. This research proposes an alternative solution to
determine the cropping pattern of paddy and CGPRT crops based on the pattern of
rainfall in the area using decision tree approach. There were three algorithms,
namely, J48, RandomTree and REPTree, tested to determine the best algorithm
used in the process of the classification of the cropping pattern in the area.
The results showed that J48 algorithm has a higher classification accuracy than
RandomTree and REPTree for 48%, 42.67% and 38.67%, respectively. Meanwhile, the
results of data testing into the decision tree rule indicate that most of the
areas in DKI Jakarta are suggested to apply the cropping pattern of 1 paddy
cropping and 1 CGRPT cropping (1 PS + 1 PL). While in Banten, there are three
cropping patterns that can be applied, they are, 1 paddy cropping and 1 CGPRT
cropping (1 PS + 1 PL), 3 short-period paddy croppings or 2 paddy croppings and
1 CGPRT cropping (3 short-period PS or 2 PS + 1 PL) and 2 paddy croppings and 1
CGPRT cropping (2 PS + 1 PL).
