SUCSOY.INS
SUCROS.CSM
(A Simple and Universal Crop Growth Simulator)
Written in Continous System Modeling Program III (CSMP III)
____________________________________________
ReWritten in insightmaker.com for Soybean
and then Called SUCSOY.INS




Validasi model SUCSOY.INS dilakukan dengan cara membandingkan hasil simulasi hasil Soybean (WSO) dengan model SUCSOY.CSM sebagai acuan, pada time step 2 hari memakai metode Integrasi RKSFX.
Input data iklim (Suhu maksimum, minimum dan Radiasi surya) memakai data Keulen, et. al.(1982), sementara data partisi tanaman kedelai memakai data Penning de Vries and van Laar (1982).

Hasil simulasi potensi hasil Soybean (WSO) pada tingkat Latitude (LAT) = -15, menunjukkan bahwa pada umur panen  420 hari diperoleh hasil masing-masing sebesar 2.150,14 kg/ha (SUCSOY.INS), dan 2.150,20 (SUCSOY.CSM);  dengan Koefisien determinasi (R2) = 1, Root Mean Square Error (RMSE) = 0,02.

Kesimpulannya SUCSOY.INS mempunyai prospek dikembangkan untuk simulasi potensi hasil kedelai beberapa varietas unggul kedelai di Indonesia; dengan mengganti input data partisi dan parameter tanaman Soybean dengan partisi dan parameter tanaman varietas unggul Kedelai di Indonesia.
