Estimation of the Harvested Ripe Stage of Sago Palm Tree in Sentani District, Jayapura, Using Quickbird Imagery Band

Abstract

Sago (Metroxylon sp) as a domestic commodity could be used as source for food industry because high carbohydrate content and subtitute ability as food resource. To determine ripe harvest sago tree, local knowledge can be implemented by identifying morphological characteristics of sago. Remote sensing is the proper method to analyze potential production of harvestable trees in sago forest. Band rationing of B2/B3 was analyzed in this research. Result showed that there are strong correlation between sago prodduction and band rationing value. Correlation coefficient (r) was 0,823 and coefficeient determination (r2) was 0,678.
