Metode Mamdani, metode Tsukamoto, status mutu airAbstract
Pada penelitian ini digunakan dua metode logika fuzzy, yaitu
metode Tsukamoto dan metode Mamdani dalam membuat sebuah model penentuan
status mutu air Danau Maninjau. Variabel input yang digunakan meliputi
suhu air, pH, DO (Dissolved Oxygen), TSS (Total Suspended Solid), TDS (Total
Dissolved Solid), BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen
Demand), NO2, dan NO3 yang dibagi ke dalam dua kategori himpunan fuzzy, yaitu
AMAN dan TIDAK AMAN. Variabel output yaitu status mutu air yang dibagi ke dalam
empat kategori himpunan fuzzy berdasarkan kriteria status mutu air, yaitu memenuhi
baku mutu (MBM), cemar ringan (CR), cemar sedang (CS), dan cemar berat (CB).
Hasil penelitian menunjukkan bahwa model status mutu air pada metode Tsukamoto
menghasilkan nilai MAPE sebesar 40% dan nilai MSE 0,472, sedangkan pada metode
Mamdani menghasilkan nilai MAPE sebesar 42% dan nilai MSE 0,678.
