Hubungan Antara Persentase Serangan Hama Tikus dengan Produktivitas Lahan Melalui Pendekatan Foto Udara

Rats pest is one of the any pests that can harm the farmers. Pest rodent attacks can decrease yields even affect to crop failures. The percentage of rice fields attack will affect the productivity inversed. The bigger percentage of rodent pests, will make the lower rice fields productivity. Therefore, this study aims to determine the relationship between percentage of pest roddents attacks with rice field productivity. Stages that must be passed in this research, among others, data retrieval, image processing analysis, regression analysis, validation and ending with the calculation of accuracy. Field data taking includes the acquisition of aerial photography and measurement of the harvest. Analysis of image processing using Adobe Photoshop CS6 software support and Matlab 2013 software. Regression analysis using Microsoft Excel 2013 software assistance using three types of regression analysis, among others: linear regression, quadratic regression, rank polynomial regression 3. Polynomial regression equation of rank 3 yields the best equation. The polynomial equation of rank 3 obtained as follows y = -1.10-6x3 + 0.0003x2 - 0,0218x + 0,6159 with a coefficient of determination equal to 0,9645 or can also be interpreted 96,45% variation of dependent variable can be explained by the free variable . The error value of the equation is 8.17% percentage of attack productivity.
