Fauzan Azima, Novizar Nazir, Nela Permata Sari


This research aims to make the adsorbent from Activated Carbon from Jengkol (ACJH) and identify the characteristics of ACJH adsorbent which have been processed. This study used CRD (Completely Randomized Design) of 5x3 factorial and two replications. Factor A (adsorbent size) consists of 5 levels: A1 (20 mesh), A2 (40 mesh), A3 (60 mesh), A4 (80 mesh), A5 (100 mesh). Factor B (activator) consists of three levels: B1 (without activator / control), B2 (activator NaOH of 0.1 M), B3 (activator HCl of 0.1 M). The data was analyzed by analysis of variance (ANOVA) and followed by Duncan's New Multiple Range Test (DNMRT) at the 5% significance level. The results showed that there was interaction between the particle size of the adsorbent and an activator on all parameters of observation. The best ACJH adsorbent has particle size of 100 mesh with 0.1 M HCl activator with characteristics: yield (23.69%), water content (2.84%), volatile content (1.13%), ash content (3.16 %),  fixed carbon (92.87%),  iodine adsorption (1064.66 mg / g) as well as having the largest pores of the adsorbent.
