Abstract
Industri batik menghasilkan limbah cair beracun dalam jumlah besar akibat penggunaan zat warna sintetis berbasis senyawa azo. Limbah ini bersifat non-biodegradable dan mencemari perairan. Penelitian ini mengembangkan sistem filtrasi limbah pewarna berbasis logika fuzzy untuk meningkatkan kualitas air limbah sebelum dibuang. Sistem menggunakan filtrasi multi-layer yang terdiri dari karbon aktif, pasir silika, dan zeolit dan dikendalikan otomatis oleh mikrokontroler Arduino Mega 2560. Parameter yang dipantau meliputi pH, turbidity, dan warna menggunakan sensor pH, turbidity, dan TCS3200. Hasil sensor diproses oleh logika fuzzy untuk menentukan aksi aktuator pompa dan solenoid valve. Pengujian selama 12 menit per siklus menunjukkan penurunan pH sebesar 0,36%, turbidity sebesar 16,41%, dan warna mendekati jernih. Sistem terbukti mampu bekerja stabil dan responsif terhadap kondisi input. Inovasi ini berpotensi diterapkan pada industri batik skala kecil sebagai solusi ekonomis dan ramah lingkungan.

The batik industry generates a large volume of hazardous liquid waste due to the use of synthetic dyes based on azo compounds. This waste is non-biodegradable and pollutes water bodies. This study developed a fuzzy logic-based dye wastewater filtration system to improve effluent quality before discharge. The system uses a multi-layer filtration method consisting of activated carbon, silica sand, and zeolite, and is automatically controlled by an Arduino Mega 2560 microcontroller. The monitored parameters include pH, turbidity, and color, using pH sensors, turbidity sensors, and a TCS3200 color sensor. Sensor data is processed by the fuzzy logic system to determine actuator actions for the pump and solenoid valve. A 12-minute batch test cycle showed a reduction in pH by 0.36%, turbidity by 16.41%, and a color output approaching clear. The system demonstrated stable operation and responsiveness to input conditions. This innovation has potential for application in small-scale batik industries as an economical and environmentally friendly solution.
