Abstract

ABSTRACT
The information on recommended fertilizer dosage and pest control that is location specific is required by the farmer for the success of agricultural cultivation. In this research, digital image analysis of the rice leaf sample was conducted to obtain primary data for determining its nutrient sufficiency status and pest attack level. Hydroponic rice planting is performed in the greenhouse with nitrogen sufficiency variations and brown plant-hopper population variations. 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 parameters, 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 in its population.
Keywords: rice crop, nitrogen, plant hopper, digital image.
