Abstract

Different sectors of industry have a need for DC motors due to their benefits, such as substantial torque, absence of reactive power loss, no disruption to power supply, and precise control. Automation in control plays a crucial role in advancing science and technology. An effective control system must fulfill specified criteria, encompassing performance indices associated with accuracy, stability, and rapid response. An optimal control system is one fashioned through the optimization of performance indices, considered optimal when parameter values are chosen to maximize or minimize the selected performance index. In the context of DC motors. In the context of speed regulation using the Linear Quadratic Regulator optimal control technique, the optimization of performance indices involves configuring the Q matrix value. This, in turn, results in the generation of the K feedback amplifier matrix and the optimal L tracking matrix for the DC motor. The process is repeated for speed regulation in the DC motor using the Linear Quadratic Regulator optimal control technique, where performance index optimization is achieved by adjusting the Q matrix value, leading to the derivation of the K feedback amplifier matrix and the optimal L tracking matrix.

Abstract

Penelitian ini mengimplementasikan sistem filtrasi air alami untuk memenuhi standar baku mutu air kelas 3 sesuai PP No. 22/2021, dengan fokus pada Total Dissolved Solids (TDS). Sistem menggunakan bahan alami seperti karang jahe, ziolit, batu apung, oyster, bioball, dan bioring untuk menyaring kontaminan air. TDS dipantau secara real-time menggunakan sensor TDS yang terintegrasi dengan mikrokontroler ESP32. Pengujian pada sampel air kolam menunjukkan penurunan TDS dari 1619 ppm menjadi 443 ppm, di bawah batas maksimum 1000 ppm. Sensor TDS menunjukkan akurasi baik dengan error 1,94% untuk air kotor dan 10,38% untuk air bersih. Hasil ini menunjukkan potensi filtrasi air alami sebagai solusi efektif dan terjangkau untuk meningkatkan kualitas air. Penelitian lebih lanjut diperlukan untuk evaluasi jangka panjang dan parameter kualitas air lainnya.
