Nafiah, Siti (2018) Rancang Bangun Automatic Water Filling Tub System Menggunakan Algoritma Fuzzy Mamdani. Sarjana thesis, Universitas Brawijaya.
Abstract
Air memegang peranan yang sangat penting dalam kehidupan manusia. Peran tersebut dapat terlihat dari tingkat kebutuhan manusia dalam penggunaan air di kehidupan sehari-hari. Namun sangat disayangkan jika air yang begitu pentingnya terbuang dengan sia-sia setiap hari karena kelalaian manusia itu sendiri. Saat ini pengisian bak mandi pada rumah-rumah masih menggunakan prinsip pengisian secara manual, yang artinya masih membutuhkan tenaga manusia untuk mengoperasikannya. Karena masih menggunakan prinsip pengisian secara manual kurang efisien, kurang menghemat waktu, dan kurang menghemat air. Pada penelitian ini dibuat sistem Automatic Water Filling menggunakan logika fuzzy mamdani. Input pada sistem ini terdapat 3 yaitu, input ketinggian air dari sensor ultrasonik HC-SR04, jumlah aliran air yang dikeluarkan dihitung menggunakan sensor waterflow G1/2, dan menghitung volume ukuran bak mandi yang didapat dari hasil input user menggunakan keypad 4x3. Selanjutnya, diproses oleh Mikrokontroller Arduino Uno dan output sistem akan ditampilkan pada LCD. Implementasi logika fuzzy mamdani pada pengisian bak mandi otomatis ini terdiri dari empat tahap yaitu, Pembentukan himpunan fuzzy, Aplikasi fungsi implikasi, Komposisi aturan, dan Defuzzifikasi. Output pada sistem ini berupa durasi lama pengisian bak mandi. Tingkat keberhasilan logika Fuzzy dilakukan dengan membandingkan nilai output sistem dengan MATLAB. Rata-rata akurasi output sistem sebesar 94,90%.
English Abstract
The water is very important things in human life. That role we can see from the level of human needs, especially when the human using the water in everyday life. But it is unfortunately if that water are waste every day because the human are negligence for himself. Today when the human charge their bathub home there are still use the principle of charging manually, it means still require the human power to operate it. Because those human still use the principle of charging manually it will be less efficient, less saving time, and less saving. In this research we made an Automatic Water Filling system which using the Fuzzy Mamdani logic method. The inputs in this system consists of 3, there are, the water level input from the HC-SR04 ultrasonic sensor, the amount of water which released will calculated using the waterflow sensor G1 / 2, and then calculates the tube size volume obtained from user input using the 4x3 keypad. And then, it will be processes by Arduino Uno Microcontroller and the output system will be displayed on the LCD. The implementation of Fuzzy Mamdani logic in automatic filling bathub consists of four stages there are, Formation of fuzzy set, Application function implication, Composition rule, and Defuzzification. The output on this system is the duration time when filling the bathtub. The success rate of Fuzzy logic we can see by comparing the output value from the system with MATLAB. The average accuracy output system is 94.90%.
