ABSTRAK

Telah dilakukan penelitian tentang degradasi limbah laundri dengan metode elektrolisis menggunakan elektroda karbon. Limbah laundri sangat berbahaya bagi lingkunan.
Limbah laundri yang sebelumnya sering dibuang ke badan air dan mencemari lingkungan dimasukkan ke dalam gelas beker yang sudah diberikan pengaduk magnetik. Elektroda karbon kemudian dipasang sedemikian rupa sehingga kedua elektroda saling berdekatan. Kemudian elektroda dihubungkan dengan sumber arus dirrect current. Dalam penelitian ini dilakukan variasi tegangan dan waktu yaitu pada tegangan5-20 volt dan 1-5 jam. Katoda dihubungkan dengan kutub positif, sedangkan anoda dihubungkan dengan kutub negatif. Pada katoda dan anoda luas yang tercelup ke dalam larutan sedalam 4 cm dengan luas permukaan 9,4 cm2.
Hasil penelitian menunjukkan bahwa arus dan waktu sangat berpengaruh terhadap presentase degradasi limbah laundri. Presentase degradasi limbah laundri yang didapatkan dengan hasil baik yaitu sebesar 50,98 % pada saat elektrolisis dengan potensi 20 volt dengan waktu elektrolisis 5 jam.

Kata kunci: anoda, katoda, elektrolisis, limbah laundri

ABSTRACT

Degradation of laundry wastewater by electrolysis method using carbon electrode has been done. The laundry watewater is very dangerous if it has discarded to environment. Research has been done to decreased the polutan of laundry wastewater.
Waste water laundrywhich previously often disposed into water and pollute the environment put into a glass beaker that has been given a magnetic stirrer. Then the carbon electrodes and placed so that both electrodes are close together. Then the electrodes is connected to the current source dirrect current. In this research, the determination of the voltage and time at 5-20 volts and the time for 1-5 hours.Cathode connected to the negative pole, while the anode is connected to the positive pole. At the cathode and anode are immersed into a solution of a broad depth of 4 cm with a surface area of 9.4 cm2.
The results showed that the current and future influence on the percentage of degradation of waste facilities. Laundry waste degradation percentage obtained with good results in the amount of  50,98 % during electrolysis with potential 20 volt and 5 hours.
