Konsentrasi Asam Fosfat Terhadap Karakteristik Arang Aktif Kulit Batang Sagu
This study aims to obtain selected characteristics of activated charcoal made from sago bark waste with several consentration of phosphoric acid as an activator. This study was conducted using a complete randomized design with five treatments and three replications. The treatments in this study were variations in H3PO4 concentration, namely A1 (H3PO4 5%), A2 (H3PO4 7,5%), A3 (H3PO4 10%), A4 (H3PO4 12,5%), and A5 ( H3PO4 15%). Observations were made on yield, moisture content, ash content, volatile matter content, bound carbon content and iodine absorption. The data obtained were analyzed statistically using IBM SPSS statistical software version 25 with analysis of variance (ANOVA) test, if Fcount ≥ Ftable then the treatment has a significant effect and the analysis will be continued with Duncan's multiple range test (DMRT) at the level of 5%. The results showed that the increase in phosphoric acid concentration used had a significant effect on yeald, moisture content, ash content, volatile matter content, bound of carbon content, and absorption of iodine. Activated charcoal with the best treatment is found in A5 treatment (H3PO4 activator concentration 15%) with a yieldof 86,85%, moisture content 1,43%, ash content of 4,77%, volatile matter content 14,10%, bound carbon of content 79,68% and absorption of iodine 837,54 mg/g.
