Pengaruh Konsentrasi Aktivator Koh Dan Lama Aktivasi Pada Pembuatan Karbon Aktif Sekam Padi

---

Rice (Oryza Sativa) is one of the main agricultural products in Indonesia. In the rice processing proses, a by product is produced in the form of rice husks. Rice husk waste has not been utilized optimally even though it is a raw material that can be developed and is available in large quantities and cheaply. Rice husks have a high carbon content, therefore rice husks can be used as raw material for making active carbon. Activated carbon has good absorption capacity so it can be used in the adsorption process. The adsorption method is very effective in removing heavy metals contained in water, even though it is only done using a relatively simple adsorption process. The process of making activated carbon is carried out in 3 stages, namely dehydration, carbonization and activation. The study used variations in activator concentration, namely 10%, 15%, 20%, 25%, and activation time of 18, 21, 24 hours. The fixed variables used were 150 gram rice husk mass, 100 mesh particle size, 400 °C carbonization temperature and 2 hours carbonization time. According to the standard SNI 06-3730-1995 the best research results were obtained at an activator concentration of 25% and activation time of 24 hour where the water content was 3%, ash content was 1,5%, volatile matter content was 12%, bound carbon content was 83,5% and iodine absorption 1027,89 mg/g. The best activated carbon was tested for adsorption to remove Fe content in peat water with an efficiency of 92% and has met the quality standard.
