Pemanfaatan Citra Landsat 7 untuk Estimasi Umur Tanaman Kelapa Sawit (Studi Kasus Di PTPN VIII Cisalak Baru, Banten)
MetadataShow full item record
Oil palm (Elaeis guineensis Jacq.) is a commodity increasingly in demand due to its increasing utilization. Indonesia together with Malaysia have 85% market share of crude palm oil (CPO) of the world. It is estimated the world CPO demand will continue to increase every year. This is due to the wide utilization in industry, increasing demand of population growth, and as comodity for production of biofuels as alternative energy sources instead of fossil fuels in vehicles. Oil palm growth is closely related to physical changes in canopy density and biomass. These changes can be monitored by remote sensing. The Landsat 7 used was data of 2010 year. This study tried to take advantage of Landsat 7 to estimate the age of oil palm . The study was conducted on land owned by PTPN VIII Cisalak Baru, Banten. The scope of the study was limited on the analysis of visual characteristics of the Landsat 7 gap-filled and make a model of an estimated age of the plant oil palm. The analysis showed that there is a gap-filled image that can be used for visual identification of objects in the composite images. Models are made in the form of a functional relationship between plant age and the combination of the selected channel in the form of linear regression. Variables used in the modeling of spectral lines and spectral values are extracted from each plant age. The model test results indicate that the model is good enough to predict the age of oil palm plantations in the range of 6-16 years.
