Abstract

Membrane technology has led to a new focus on water and wastewater treatment. This is due to severaldrawback of the conventional water treatment i.e release the toxic and carcinogenic materials. In thisresearch, the use Reverse Osmosis (RO) membrane for treating river and well water to obtain clean anddrinking water was studied. The variables studied were effect of pressure and operation time to themembrane flux. The pressure was varied from 1 to 7 bar and the operation time was varied from 15 to 60minutes. The content of Total Dissolved Solid (TDS) in the permeate product was analyzed. The resultsshown that the increase of pressure would increase the membrane flux and decrease TDS. The increaseof the operation time would decrease membrane flux and TDS. The reverse osmosis membrane wassuccessfully applied to treat the river and well water. The product fulfill national standard quality ofdrinking water by viewpoint of the TDS content

Abstract

The petroleum is the fuel derived from fossil which can not be renewable and the deposit in the earth is not morenow. In the middle 2008, the price of petroleum achieved US$ 147/Barrel because the supply of petroleum toworld market was reduced. This situation forced the appearance of the alternative energy which can replace thefossil fuel in the future. Their result of combustion has low emission so that they can be reduced the pollutionand were environment friendly. Biobriquette is the one alternative energy which expected to be able to replacethe kerosene and LPG. This research aims to get the exactly composition and type in manufacturing ofbiobriquette from cashew nut shell and jatropa shell waste. The variables choose as the independence variablewas the type of waste (cashew nut shell and jatropa shell) and the compositions (40, 60, 80 and 100%). Theothers are the fixed variable such as the size of briquette 4 cm and the total weight/biquette 25 g. The responseor parameters observed in the experiment were the color, the value of calor, the length of combustion and thecolor of fire. The result of experiment showed that composition of the material greatly affected the quality ofbriquette produced. The composition 100% owns the highest calor of combustion. The calor of Jatropa wastewas higher than that of cashew nut shell.
