Angka Melek Huruf (AMH) merupakan salah satu komponen indeks pembangunan manusia (IPM). Mengacu pada data Badan Pusat Statistik (BPS) Provinsi Bali 2018, AMH Kabupaten Karangasem pada tahun 2018 memiliki nilai paling rendah yaitu 84,91 persen. Nilai ini cukup jauh dibandingkan AMH Kota Denpasar yang hampir mencapai 100 persen, tepatnya 98,02 persen. Dengan demikian, penting untuk membuat suatu model yang dapat memprediksi nilai AMH di Kabupaten Karangasem pada tahun yang akan datang. Penelitian ini menggunakan data Persentase Penduduk Miskin (PPM) dan Angka Partisipasi Sekolah (APS) di Kabupaten Karangasem pada tahun 2007 s.d. 2018 sebagai input dan AMH Kabupaten Karangasem pada tahun 2007 s.d. 2018  sebagai output. Setelah diproses menggunakan algoritma backpropagation, diperoleh model dengan overfitting paling minimal yaitu model 2-5-1 dengan rata-rata error per iterasi sebesar 0.00049386.

Myopia is a vision disorder that causes the sufferers unable to see distant objects. The degree of myopia in humans can changes, both increasing and decreasing. The increasing of myopia degree is proportional to the potential of other visual disorders, such as cataracts, retinal detachment, and glaucoma. Therefore, the increasing of myopia degree needs to be watched out. Several previous studies only considered the time factor in predicting the changes of myopia degree. In fact, the changes of myopia degree also influenced by some factors that related to individual identity and behavior. This study aims to predict the changes of myopia degree in humans based on some factors that causes myopia.. This study uses data that has been scaled with the fuzzy membership function to be processed with ANN for predicting the changes of myopia degree. By ANN 6-2-3 architecture that uses 80 training data, 20 testing data, and 1 predictive data, the prediction result of the changes of  myopia degree in the right eye is 1.1 dioptri, in the left eye is 1.2 dioptri and the accumulated of both is 2.3 dioptri with accuration values 87.79%, 78.47%, and 83.21%.
