Kebutuhan air bersih di PDAM Kota Pontianak untuk golongan pelanggan sosial, nonniaga, niaga, dan industri telah dianalisis dengan menggunakan metode Levenberg-Marquardt. Hasil analisis menunjukan bahwa fungsi matematika terbaik untuk pelanggan sosial adalah polinomial orde 5 dengan nilai korelasi sebesar 0,905 dan RMSE sebesar 4,77×102. Kemudian untuk pelanggan nonniaga dan pelanggan niaga, fungsi matematika terbaik adalah polinomial orde 6 dengan nilai korelasi masing-masing pelanggan adalah 0,956 dan 0,878 serta RMSE sebesar 9,25×104 dan 2,91×104. Selanjutnya untuk pelanggan industri, fungsi matematika terbaik adalah polinomial orde 4 dengan nilai korelasi sebesar 0,719 dan RMSE sebesar 8,43×102 . Berdasarkan fungsi matematika yang telah diperoleh, hasil prediksi kebutuhan air bersih dari tahun 2017 hingga tahun 2019 menunjukkan bahwa golongan pelanggan niaga memiliki peningkatan yang paling tinggi dengan rata-rata laju pertumbuhan sebesar 80,4%.References
