Cholesterol is a metabolites that contain sterol fat. It is important for every cell of the body in order to perform its function such as the formation of vitamin D, cortisol hormones and reproductive hormones. Increase concentration of cholesterol or hypercholesterolemia is a predisposed condition of cardiovascular disease. Based on previous studies have reported that glucomannan and activated charcoal can lower cholesterol, but a combination of the two in a formulation has not been reported. Glucomannan which is one of the most important chemical components in the tubers of Amorphophallus is a polysaccharide composed of units of D-glucose and D-mannose. Ties that make up the form of glucomannan polymer is a β-1,4-glycosides. Activated charcoal is a material that has the ability as an adsorbent, are amorphous, and has the configuration of carbon atoms shaped plates bonded carbon atoms with covalent bonds in the hexagonal sides. The objective of this study was to examined the role of various formulation of glucomannan from Amorphophallus and activated charcoal to reduce cholesterol levels in adult male rats of Sprague Dawley strain. Stages of this research is the isolation of glucomannan from Amorphophallus flour, activated charcoal manufacture, formulation and characterization using instruments, in vivo testing, and cholesterol analysis. Experimental animals used in this study was 35 adult male Sprague Dawley with body weight ranged from 160 to 200 g. Animals were divided into 7 treatment groups consuming high-fat diet (HFD) and glucomannan, HFD and teak sawdust activated charcoal, HFD and coconut fiber activated charcoal, HFD and glucomannan-activated charcoal 1:1, HFD and glucomannan-activated charcoal 2:1, HFD and glucomannan-activated charcoal 1:2 and HFD without treatment as control group. Total plasma cholesterol was analyzed at baseline and end of study after 5 weeks of treatment. The results of the analysis of Fourier transform infrared showed that the isolated glucomannan has the same functional group with standard glucomannan. The results of the analysis of pyrolysis gas chromatography-mass spectroscopy indicate that the relative percentage of sugar in the glucomannan derivatives isolated by 14.2% and glucomannan flour standard 15.5%. The results of the analysis of X-ray diffractometer indicates the degree of crystallinity of teak sawdust activated charcoal powder was 32.8% and coconut activated carbon fibers by 40.3%. The results of the analysis of scanning electron microscope showed that coconut fiber activated charcoal has uniform pore shape better than teak sawdust activated charcoal. The conclusion of this research that the highest decrease in cholesterol level was in the treatment group HFD and glucomannanactivated charcoal 1:1, with a decrease in total cholesterol levels by 37.4%, decreased levels of low density lipoprotein by 49.7%, and decreased triglyceride levels by 18.3%
