Sistem Peramalan Waktu Masak Fisiologis Benih Padi Menggunakan Double Exponential Smoothing

The success of the rice harvest is influenced by various factors, one which selection quality seeds. Good seeds are those obtained during physiological maturity where moisture content in not too low/high. cooking time can be done calculating heat accumulation and testing germination. Heat total energy from solar radiation received plants, this value calculated recording maximum, minimum, humidity temperature data continuously for 90-120 days. Meanwhile, post-harvest laboratory tests were carried out Temperature that stored processed quickly course could predicted ripening better. Therefore article, a web-based forecasting system with double exponential smoothing method was developed supported graphical display development. This research conducted on 3 varieties namely IR64, Sinta Nur, Ciherang. yield conveyed IR64 variety reached 85% germination 1147 105 DAS. Nur had 92% 86% Ciherang 1266 at 115 In process, MAPE 0.205 alpha 0.9 beta 0.1.
