Abstract

Air bersih menjadi kebutuhan utama bagi manusia dalam menjalankan kegiatan sehari-hari. Permasalahan yang timbul yakni sering dijumpai bahwa kulaitas air tanah maupun air sungai yang digunakan masyarakat kurang memenuhi syarat sebagai air minum yang sehat bahkan di beberapa tempat bahkan tidak layak untuk diminum. Di daerah berkapur air akan bersifat sadah yaitu terdapat mineral berlebih yang terkandung didalamnya yang dapat menyebabkan bahaya bagi kesehatan. Untuk mengolah air tersebut secara konvensional maka akan ditambahkan bahan kimia di dalamnya, yang bahkan akan berbahaya jika dipakai secara terus-menerus. Berdasarkan hal itu dilakukanlah penelitian Analisis Efisiensi Metode Elektrokoagulai Ultrasonik Untuk Mengurangi Kadar Kesadahan Pada Air. Pada penelitian kali ini menggunakan plat elektroda berbahan aluminium dengan variasi jumlah plat 3 dan 5 pasang serta jarak antar elektroda sebesar 1 cm, 1,5 cm 2 cm. Pada penelitian ini melakukan perbandingan metode elektrokoagulasi dengan elektrokoagulasi ultrasonik. Diketahui bahwa nilai awal air yang akan di proses sebesar 442,87 mg/L hasil dari penelitian ini berupa perbandingan pengurangan kadar kesadahan. Didapatkan bahwa pada metode elektrokoagulasi pada konfigurasi 3 plat pada jarak 1cm, 1,5 cm, 2 cm berturut-turut adalah 38,7 %, 37% dan 29,8% pada konfigurasi 5 plat pada jarak 1 cm, 1,5 cm, 2 cm berturut turut adalah sebesar 37%, 48,3%, 41,9%. Pada metode elektrokoagulasi ultrasonik didapatkan hasil pada 3 pasang plat dengan variasi jarak 1 cm, 1,5 cm, 2 cm adalah 46,7%, 53,2%, 50%, dan pada 5 pasang plat didapatkan sebesar 56,4%, 62,9%, dan 59,6%. Dari data tersebut pada konfigurasi metode elektrokoagulasi ultrasonik dengan variasi 5 pasang plat dan pada jarak 1,5 cm menghasilkan pengurangan kadar kesadahan paling besar yaitu sebesar 62,9%. ====================================================================================================================================
Clean water is the main requirement for humans in carrying out their daily activities. The problem that arises is that it is often found that the quality of groundwater and river water used by the community does not meet the requirements as healthy drinking water, even in some places it is not even suitable for drinking. In calcareous areas the water will be hard, that is, there are excess minerals contained in it that can cause harm to health. To treat the water conventionally, chemicals will be added to it, which will even be dangerous if used continuously. Based on this, a study was conducted to analyze the efficiency of the ultrasonic electrocoagulation method to reduce hardness levels in water. In this study, we used aluminum electrode plates with variations in the number of plates of 3 and 5 pairs and the distance between electrodes of 1 cm, 1.5 cm and 2 cm. This study compares the electrocoagulation method with ultrasonic electrocoagulation. It is known that the initial value of water to be processed is 442.87 mg/L. The result of this study is a comparison of the reduction of hardness levels. It was found that in the electrocoagulation method in the configuration of 3 plates at a distance of 1 cm, 1.5 cm, 2 cm respectively were 38.7%, 37% and 29.8% in the configuration of 5 plates at a distance of 1 cm, 1.5 cm, 2cm respectively were 37%, 48.3%, 41.9%. In the ultrasonic electrocoagulation method, the results obtained in 3 pairs of plates with a distance variation of 1 cm, 1.5 cm, 2 cm are 46.7%, 53.2%, 50%, and in 5 pairs of plates obtained by 56.4%, 62.9%, and 59.6%. From these data, the configuration of the ultrasonic electrocoagulation method with a variation of 5 pairs of plates and at a distance of 1.5 cm resulted in the greatest reduction in hardness levels, namely 62.9%.
