BAB V
KESIMPULAN DAN SARAN
5.1. Kesimpulan
Dari hasil percobaan jaringan dengan 3 layer untuk algoritma Back Propagation dan 2 layer untuk LVQ dilakukan input neuron input berupa bulan dan
volume curah hujan, maka dapat dibuat kesimpulan adalah sebagai berikut:
1. Algoritma Back Propagation lebih dekat dalam melakukan prediksi data curah
hujan 30 tahun terakhir dibandingkan dengan LVQ. 2.
Algoritma backpropagation dan LVQ memiliki tingkat akurasi lebih baik pada musim kemarau, dengan tingkat akurasi untuk algoritma Backpropagation antara
75 – 99 dan algoritma LVQ sebesar 60 – 82 . 3.
Untuk kedua algoritma diatas, pengaruh fenomena El-Nino dan La-Nina tidak begitu signifikan.
5.2. Saran
Adapun saran-saran untuk penelitian ini adalah:
1. Perlu dilakukan pengujian lebih lanjut dengan menggunakan beberapa parameter
cuaca seperti angin, temperature, indeks SOI dan lain lain 2.
Perlu dilakukan variasi pada parameter jaringan syaraf tiruan, agar diperoleh hasil yang lebih akurat lagi.
