This project aims to study the physical and chemical properties of soft fillings, raw. Stuffed Baked soft and light filling of charcoal from burned cassava stems, with a temperature of 300 degrees Celsius for 30 minutes by studying the physical properties include density, appear. Characteristics, surface and internal structure using scanning electron microscope images (Scanning Electron Microscope: SEM) and chemical properties of the element elements, which include analysis of X-Ray Energy Dispersive Spectrometer techniques: EDX, the ability to absorb water, and performance.App to absorb solvents methanol blue polyester by measuring the absorption spectrophotometer UV-Vis machine at 665 nm wave length. Results from EDX techniques found that the carbon element quantity of coal increased from 54.84% 67.00% by weight, and when analyzing pore texture in coal by using SEM technique photos 500 x magnification found 150 µm pore size volumes increase by more than filling in a light and clear, raw and filling c-stores.Onop the density of light crude filling has a value of 0.029 grams per cubic centimeter a soft filling value 0.024 g per cubic centimeter and charcoal has a value of 0.013 grams per cubic centimeter. The ability to absorb the water of light crude, and the soft bun, baked stuffed charcoal is 11.37 and 6.06 per gram by gram weight, 35.59, respectively. Efficiency in absorbing solvents soft Polyester filling lukhong-mail, raw. Stuffed Baked soft coal and increase the duration by which time 150 minutes with charcoal to absorb the best value equal to the activated charcoal 1 gram weight mg 2.984 and filling light crude is equal to 0.16 milligrams per gram of crude, and the soft filling weight filling baked soft has a value of 0.82 mg/stuffed baked soft weight 1 g.
