Abstract

Estimation of Rice Production Using Landsat 8 Satellite in Tabanan District

Agricultural sector is currently a very important sector considering that every
human being needs food to survive and as a source of energy to carry out daily
activities. Production estimation that are accurate and timely can provide information
for planners and decision-makers to formulate appropriate policies when conditions
are inadequate or overstocked. The technology that can be used is remote sensing using
the Landsat 8 satellite. The greenness level parameters of plants (Vegetation Index)
obtained through satellite image analysis can be used to estimate rice production. The
research area is located in Tabanan Regency. Estimation of rice production is done by
the equation y = 2.0442e1.8787x, where x is the NDVI value from the Landsat 8 image
and y is the result of rice production. The estimation results using Landsat 8 are one
season production in tons/ha. The accuracy test is done by paired t-test and correlation
analysis. Paired t-test shows that there are no significant differences between rice
production estimation from BP3K and rice production estimation using Landsat 8.
Correlation analysis results show that there is a linear relationship between statistical
results and estimation results with R2value 0.9682 with the equation y = 1.0099x -
0.0794, where y and x are Landsat 8 estimates in tons/ha and BP3K data respectively,
with a Standard Error (SE) of 0.1984.
