Abstract
Dalam proses produksi industri pertambangan iodium, dihasilkan limbah cair yang dibuang ke Instalasi Pengolahan Air Limbah (IPAL). Dalam setahun terakhir, terdapat ganggang pada air limbah industri pertambangan iodium. Adanya ganggang merupakan indikasi bahwa zat pencemar pada air limbah belum tereduksi dengan baik sehingga tidak aman apabila dibuang langsung ke lingkungan. Oleh karena itu, diperlukan suatu metode untuk mereduksi zat pencemar yang efisien dan inovatif. Salah satunya yaitu adsorpsi menggunakan arang batok kelapa.
Tujuan dari penelitian ini yaitu menentukan nilai efisiensi removal adsorben arang batok kelapa pada parameter warna, PV, COD, dan BOD, beserta masing-masing nilai adsorpsi isotermisnya menggunakan analisis jartest secara batch, dan menentukan nilai konstanta kinetika dan kapasitas adsorben arang batok kelapa pada parameter warna, PV, COD, dan BOD menggunakan down flow fixed bed adsorption column reactor secara continue.
Parameter yang digunakan pada penelitian ini yaitu warna, PV, COD, BOD, beserta nilai adsorpsi isotermis, kinetika adsorpsi, dan kapasitas adsorben pada setiap parameter. Sistem adsorpsi yang digunakan adalah sistem batch dan continue. Variasi penelitian yang digunakan yaitu konsentrasi air limbah (100%, 75%, dan 50%), ukuran butiran adsorben (mesh 8, 10, dan 12), dan massa butiran adsorben (12,5 gr, 25 gr, dan 50 gr), serta ketinggian adsorben pada kolom adsorpsi (5 cm, 7,5 cm, dan 10 cm).
Hasil penelitian pada analisis adsorpsi secara batch didapat bahwa efisiensi removal warna, PV, COD, dan BOD menggunakan arang batok kelapa masing-masing sebesar 0 – 52 %, 1,3 – 27,69 %, 28,13 – 53,13 %, dan 7,41 – 35,19 % dengan nilai kinetika adsorpsinya masing-masing sebesar 23 – 43 x 10-6 mg warna / mg adsorben, (1 – 4) x 10-4 mg PV / mg adsorben, (1 – 9) x 10-4 mg COD / mg adsorben, dan (75 – 83) x 10-6 mg BOD / mg adsorben. Konsentrasi air limbah, ukuran butiran adsorben, dan massa adsorben optimum dari sistem batch adalah 50%, diameter mesh 12, dan 12,5 gr/L. Hasil penelitian pada analisis adsorpsi secara continue didapat bahwa nilai kinetika adsorpsi pada parameter Warna, PV, COD, dan BOD masing-masing sebesar -0,016 – 0,005 L/mg.jam, -5,49 – 9,41 L/mg.jam, 0,31 – 3,35 L/mg.jam, dan 0,16 – 0,98 L/mg.jam. Sedangkan, nilai kapasitas adsorbennya masing-masing sebesar -0,003 – 0,005 mg warna / mg adsorben, [-953 – (-4)] x 10-6 mg PV / mg adsorben, [-23 – (-1)] x 10-5 mg COD / mg adsorben, dan [-39 – (-4)] x 10-5 mg BOD / mg adsorben.

In the production process of the mining industry iodine, liquid waste is discharged into the Waste Water Treatment Plant (WWTP). In the past year, there is algae in the mining industry waste water iodine. The presence of algae is an indication that the contaminants in the waste water has not been reduced properly so insecure when discharged directly into the environment. Therefore, we need a method to reduce pollutants efficient and innovative. One of them is the use of charcoal adsorption.
The purpose of this study is to determine the value of the removal efficiency of the adsorbent charcoal in color parameters, PV, COD and BOD, and their respective values adsorption isotermisnya using analysis jartest batch, and determine the value of the constant kinetics and capacity adsorbent charcoal on parameters color, PV, COD and BOD using a down flow fixed bed reactor a continuously adsorption column.
The parameters used in this study is the color, PV, COD, BOD, showing the adsorption isotherm, adsorption kinetics, and the capacity of the adsorbent for each parameter. Adsorption system used is a batch system and continue. Variations of research used is the concentration of waste water (100%, 75% and 50%), grain size adsorbent (mesh 8, 10, and 12), and the mass of adsorbent granules (12.5 g, 25 g and 50 g) , and the height of the adsorbent in the adsorption column (5 cm, 7.5 cm, and 10 cm).
Results of research on batch adsorption analysis found that the removal efficiency of color, PV, COD and BOD use of charcoal each by 0-52%, 1.3 to 27.69%, from 28.13 to 53.13%, and 7.41 to 35.19% with the value of each adsorption kinetics is 23-43 x 10-6 mg color / mg adsorbent, (1-4) x 10-4 mg PV / mg adsorbent, (1-9) x 10-4 mg COD / mg adsorbent, and (75-83) x10-6 mg BOD / mg adsorbent. Concentration of waste water, the grain size of the adsorbent, and the optimum adsorbent mass of a batch system is 50%, the diameter of the mesh 12, and 12.5 g / L. The results of research on a continuously adsorption analysis found that the adsorption kinetics parameter value Color, PV, COD and BOD respectively -0.016 - 0.005 L / mg. hour, -5.49 - 9.41 L / mg.hour, 0.31 to 3.35 L / mg.jam, and 0.16 to 0.98 L / mg.hour. Meanwhile, the value of the capacity of adsorbent respectively -0.003 – 0.005 mg color / mg of adsorbent, [-953 – (-4)] x 10-6 mg PV / mg of adsorbent, [-23 – (-1)] x 10- 5 mg COD / mg adsorbent, and [-39 – (-4)] x 10-5 mg BOD / mg adsorbent.
