Abstract
ABSTRACT
The information of recommended fertilizer dosage and pest control that is location specific
is required by the farmer for the success of its agricultural cultivation. In this
research, digital image analysis of the rice leaf sample was conducted to obtain a basis
data for determining its nutrient sufficiency status and pest attack level. Hydroponic rice
planting is performed in the green house with variations of nitrogen sufficiency and
variations of brown plant-hopper population. Along the rice crop development, rice leaf
photography is performed to capture the digital image of rice leaf from various
treatments of nitrogen sufficiency variation, pest attack level variation, and plant period
variation. The process of digital image processing is performed to obtain image
parameter, which are Red (R), green (G), dan blue (B). The variation of nitrogen content
from 10% - 150% of recommended dosage produces various rice leaf greenness,
amount of tillers, amount of panicles, and plant biomass weight. The increase of
nitrogen content from 10% - 150% causes color diversity from greenish yellow with the
value of R: 86, G: 131, and B: 46, to dark green with the value of R: 119, G: 169, and
B: 72. Rice crop that is attacked by brown plant-hopper changes from green with the
value of R: 206, G: 193, and B: 159 into brownish yellow with the value of R: 196, G:
98, and B: 86 along with the increase of it population.
Keywords: rice crop, nitrogen, plant hopper, digital image.
