Abstract: | Salah satu cara untuk memantau kondisi lahan adalah dengan melakukan
identifikasi perkembangan tanaman melalui respon spektral menggunakan
spektroradiometer, yaitu alat ukur cahaya yang mampu mengukur radiasi spektral
pada rentang panjang gelombang yang dipancarkan dari suatu objek. Penelitian ini
bertujuan untuk melakukan analisis pola respon spektral tiga varietas padi, ubi jalar
dan bengkuang berbasis dari data spektroradiometer dan membandingkan
karakteristik pola spektral hasil pengukuran spektroradiometer dan citra drone
multispektral. Penelitian ini dilakukan di Desa Situ Gede, Kecamatan Bogor Barat,
Kota Bogor. Respon spektral tanaman padi, ubi, dan bengkuang berbeda dan respon
spektral setiap jenis tanaman juga berbeda pada panjang gelombang yang berbeda.
Semakin bertambah umur tanaman maka nilai reflektan pada rentang inframerah
akan meningkat. Nilai reflektan varietas Nawacita pada rentang inframerah
memiliki nilai reflektan yang lebih tinggi dibanding dengan varietas Siliwangi dan
Palmerah karena dipengaruhi oleh struktur internal daun, lebar kanopi, dan
konsentrasi air. Hubungan antara nilai reflektan citra drone dengan nilai reflektan
spektroradiometer untuk tanaman menunjukan rata-rata R² diatas 0,6 One of the ways to monitor land condition is identify plant growth through a spectral response using a spectroradiometer, a light measuring instrument capable of measuring spectral radiation in the wavelength range emitted from an object. This study aims to analyze the spectral response patterns of three varieties of rice, sweet potato and jicama based on spectroradiometer data and to compare the characteristics of the spectral pattern measured by the spectroradiometer and multispectral drone photos. This research was conducted in Situ Gede Village, West Bogor District, Bogor City. The spectral response on rice, sweet potato and jicama plants was different and the spectral response of each plant type was also different at different wavelengths. The older plants age, the reflectance value in the infrared range will increase. The reflectance value of the Nawacita variety in the infrared range has a higher reflectance value than the Siliwangi and Palmerah varieties because it is influenced by the internal structure of the leaves, the width of thecanopy, and the water concentration. The relationship of the reflectance value of the drone image with the spectroradiometer reflectance value for plants shows an average of R² above 0,6. |
