Abstract

Sea water treatment technology into freshwater is known as desalination. a desalination technique that is both effective and economical is desalination with evaporation. This study aims to determine the effect of roofing materials on the amount of freshwater products produced. The study was conducted using a miniature evaporative tub that has a roof-like shape. Evaporative tubs measuring 1m x 1m x 0.02m material of laminated wood. 20 liters of brackish water is pumped into the tub. The water in the tub is then closed using a roof designed like a roof made of fiberglass and polycarbonate. Brackish water is left in contact with the sun for 24 hours. As a result of heat transfer from sunlight to evaporation tub, brackish water experiences evaporation. The steam moves upward and is captured by the roof wall then undergoes condensation resulting in fresh water. The conclusion obtained is miniature of evaporative desalination roof using fiberglass material obtained 427 mL result while using polycarbonate material obtained fresh water equal to 136 mL.

Abstract

Asbuton is a rock that contain the bitumen. Asbuton can be used as road construction alternatives after extracting bitumen from the mineral. A method for separating bitumen is separation process using hot water medium. The process was carried out in a stirred tank, 200 grams of asbuton was mixed with diesel oil and added by hot chemical solution (surfactant) in the digestion tank. The Separation process in the extractor was made at then the speed of stirrer were set according to the variable and time was set 30 minutes. After the complete process, the mixture was moved into a beaker glass and 500 ml hot water was added. The mixture of diesel oil and bitumen will float in the surface then the density will be measured to determine the bitumen concentration. It can be concluded that concentration of surfactant solution and speed of stirrer gave the significant results. The highest recovery percentage of bitumen is 81,99 %. Keywords: asbuton, hot water, surfactant, speed of stirrer
