Abstract

Penelitian ini berkonsentrasi pada pengembangan sistem otomatisasi reaktor fotokatalisis untuk meningkatkan efisiensi mengolah limbah pewarna remazol. Pewarna remazol tidak dapat terurai secara alami sehingga dapat menyebabkan pencemaran, khususnya pada lingkungan perairan. Sistem bekerja dengan mengalirkan air limbah remazol menuju tangki fotokatalisis kemudian lampu UV-C dan motor pengaduk aktif. Selanjutnya katalis akan dipompa menuju tangki fotokatalisis dan proses fotokatalisis berjalan selama satu jam. Lalu solenoid valve dan pompa DC akan aktif untuk mengalirkan air hasil fotokatalisis menuju proses selanjutnya. Dalam penelitian ini, dilakukan fotokatalisis air pewarna remazol kadar 10 ppm kapasitas 25 liter. Proses fotokatalisis menggunakan ZnO dan lampu UV-C dengan irradiance sebesar 2,051 mW/cm^2. Sensor yang digunakan dalam penelitian ini yaitu sensor level switch dan sensor Total Dissolved Solids (TDS). Sensor level switch berfungsi untuk mengotomatisasi pengisian dan pemindahan air dalam tangki fotokatalisis. Sensor TDS digunakan untuk monitoring nilai partikel terlarut selama proses fotokatalisis. Aktuator yang digunakan pada penelitian ini yaitu pompa celup, pompa DC 12 volt, solenoid valve, motor AC, dan pompa peristaltik. Adapun fungsi masing-masing aktuator yaitu pompa celup berfungsi memompa air limbah menuju tangki fotokatalisis; pompa DC 12 volt berfungsi memompa air dalam tangki fotokatalisis setelah proses fotokatalisis selesai; solenoid valve berfungsi membuka atau menutup aliran keluaran tangki fotokatalisis; motor AC dilengkapi pengaduk berfungsi mengaduk air limbah dengan larutan ZnO didalam tangki fotokatalisis; dan pompa peristaltik berfungsi mengalirkan larutan ZnO menuju tangki fotokatalisis. Berdasarkan respons dinamik, sistem mampu berjalan stabil sesuai dengan parameter yang telah ditentukan. Dalam pengujian dilakukan variasi volume katalis sebesar 12 ml, 25 ml, dan 37 ml. Hasilnya menunjukkan peningkatan nilai Total Dissolved Solids (TDS) sebesar 13,73%; 20,93%; dan 18,66% secara berurutan. Dengan adanya alat ini diharapkan dapat berkontribusi terhadap penelitian teknologi fotokatalisis dalam melakukan pengolahan limbah pewarna.

This research concentrates on developing a photocatalysis reactor automation system to improve the efficiency of treating remazol dye effluent. Remazol dyes are not biodegradable, so that they can cause pollution, especially in the aquatic environment. The system works by flowing remazol wastewater into the photocatalysis tank, then the UV-C lamps and stirring motor are activated. Furthermore, the catalyst will be pumped into the photocatalysis tank and the photocatalysis process will run for one hour. Then the solenoid valve and dc pump will be active to drain the photocatalyzed water to the next process. In this study, photocatalysis of 10 ppm remazol dye water with a capacity of 25 liters was carried out. The photocatalysis process uses ZnO and UV-C lamps with an irradiance of 2.051 mW/cm^2. The sensors used in this research are level switch sensor and Total Dissolved Solids (TDS) sensor. The level switch sensor serves to automate the filling and transfer of water in the photocatalysis tank. The TDS sensor is used to monitor the value of dissolved particles during the photocatalysis process. The actuators used in this study are a submersible pump, a 12-volt DC pump, a solenoid valve, a mixing motor, and a peristaltic pump. The function of each actuator is that the a submersible pump functions to pump wastewater into the photocatalysis tank; a 12-volt DC pump functions to pump water in the photocatalysis tank after the reaction is complete; a solenoid valve functions to open or close the output flow of the photocatalysis tank; an AC motor equipped with a stirrer functions to stir wastewater with ZnO in the photocatalysis tank; and a peristaltic pump functions to flow ZnO to the photocatalysis tank. Based on the dynamic response, the system can run stably according to predetermined parameters. The volume variation of the catalyst is 12 ml, 25 ml, and 37 ml. The results show an increase in Total Dissolved Solids (TDS) value by 13.73%; 20.93%; and 18.66% respectively. With this device, it is expected to contribute to the research of photocatalysis technology in conducting dye waste treatment.
