Prediksi Unsur Hara Sampel Tanah Menggunakan Near Infrared Spectroscopy
نویسندگان
چکیده
Penentuan karakteristik dan konsentrasi unsur hara tanah perlu dilakukan metode analisa untuk perlakuan lahan serta ketepatan dosis jenis pemupukan dalam optimalisasi produktivitas tanaman. Metode alternatif analisis kandungan sampel secara cepat, efektif, ramah lingkungan, tidak merusak dapat menggunakan near infrared spectroscopy (NIRS). Sampel yang digunakan berasal dari Laboratorium Tanah, P3GI. Parameter sebagai perkiraan yaitu pH, nitrogen (N, %), fosfat (P2O5, ppm), kalium (K2O, ppm). Sebanyak 64 kalibrasi 30% validasi. Spektrum NIRS diperoleh FOSS XDS rapid content analysis (400 – 2.400 nm, reflectance mode) pengolahan data statistik vision software dengan model dibangun berdasarkan partial least square (PLS). Penelitian ini didapatkan hasil evaluasi bahwa memprediksi parameter pH (R2 = 0,951; r2 0,511; SEP 1,428; RPD 1,440; consistency 22,321%; 0,1776) R2 0,767; 0,665; 0,025; 1,749; 97,745%; 0,0131) performanya masih cukup baik, sedangkan lainnya kurang. Berdasarkan tersebut, memiliki potensi kualitas namun ditingkatkan keakuratanya.

متن کاملNondestructive Firmness Estimation of Tomato Fruit Using Near-Infrared Spectroscopy
Today, nondestructive methods are widely used to determine the quality of agricultural products. Meanwhile, visible and near-infrared (Vis/NIR) spectroscopy is regarded as one of the most widely used methods in the field of quality assessment of agricultural products. In this study, a system was developed to measure the Vis/NIR spectra of tomato fruit samples in the half-transmittance mode of m...
متن کاملEditorial Near Infrared Spectroscopy
The pursuit to identify vulnerable plaque has been relentless, as it is responsible for major healthcare problems, such as sudden cardiac death and acute coronary syndromes, including acute myocardial infarction (AMI). Per definition, vulnerable plaque is plaque that is prone to rupture but has not yet ruptured.1 The features associated with vulnerable plaque include a large lipid core, thin fi...
