Abstract

Clean water distribution systems in high rise buildings often experience pressure instability due to variations in water demand on each floor. Conventional control systems are generally less responsive to load changes, resulting in uneven water pressure, energy waste, and reduced equipment lifespan. Based on these conditions, this study aims to implement the Fuzzy Mamdani logic method in a clean water pump pressure control system to maintain pressure stability and improve energy efficiency. This research designs a prototype of a clean water pump pressure control system based on an ESP32 microcontroller, using a pressure sensor as the input variable and a PWM signal as the output to regulate pump speed through a BTS7960 motor driver. Testing was conducted under various load conditions by opening water valves on multiple floors. The test results show that the pressure sensor has an Error range of 2.27% to 6.03%. In the system without Fuzzy control, the pressure increased from 21.17 psi to 34.40 psi as the load decreased, with motor current rising to 9.50 A. In contrast, the system with Fuzzy Mamdani control was able to maintain pressure close to the 21 psi setpoint within a range of 21.04–21.30 psi, accompanied by a significant reduction in motor current to 4.58 A. The implementation of Fuzzy Mamdani control proved to enhance the system’s energy efficiency, achieving a maximum power saving of 51.79%. Furthermore, the implementation results show good agreement with MATLAB simulations, with a maximum PWM Error of 3.28%. Therefore, the Fuzzy Mamdani-based clean water pump pressure control system is considered effective and feasible for application in high-rise buildings. Keywords: Fuzzy Mamdani, Water pressure control, ESP32, Energy efficiency Sistem distribusi air bersih pada gedung bertingkat sering mengalami ketidakstabilan tekanan akibat variasi kebutuhan air di setiap lantai. Sistem pengendalian konvensional umumnya kurang responsif terhadap perubahan beban, sehingga menyebabkan tekanan air tidak merata, pemborosan energi, serta penurunan usia peralatan. Berdasarkan kondisi tersebut, penelitian ini bertujuan untuk mengimplementasikan metode logika Fuzzy Mamdani pada sistem pengendali tekanan pompa air bersih guna menjaga stabilitas tekanan dan meningkatkan efisiensi energi. Penelitian ini merancang sebuah prototipe sistem pengendali tekanan pompa air bersih berbasis mikrokontroler ESP32 dengan sensor tekanan sebagai variabel masukan dan sinyal PWM sebagai keluaran untuk mengatur kecepatan pompa melalui driver motor BTS7960. Pengujian dilakukan dengan variasi kondisi beban melalui pembukaan keran pada beberapa lantai. Hasil pengujian menunjukkan bahwa sensor tekanan memiliki tingkat Error antara 2,27% hingga 6,03%. Pada sistem tanpa kontrol Fuzzy, tekanan meningkat dari 21,17 psi hingga 34,40 psi seiring berkurangnya beban, dengan arus motor meningkat hingga 9,50 A. Sebaliknya, sistem dengan kontrol Fuzzy Mamdani mampu menjaga tekanan mendekati setpoint 21 psi pada rentang 21,04–21,30 psi, disertai penurunan arus motor hingga 4,58 A. Penerapan kontrol Fuzzy Mamdani terbukti meningkatkan efisiensi energi sistem dengan penghematan daya tertinggi mencapai 51,79%. Selain itu, hasil implementasi menunjukkan kesesuaian yang baik dengan simulasi MATLAB, dengan Error PWM maksimum sebesar 3,28%. Dengan demikian, sistem pengendali tekanan pompa air bersih berbasis Fuzzy Mamdani dinyatakan efektif dan layak diterapkan pada gedung bertingkat.
