Abstract

Experimental testing using coconut oil produced by dry method on engine has been conducted in the Laboratory of Energy Conversion, Mechanical Engineering, Mataram University. The purpose was to evaluate the effect of using this coconut oil on the engine performance. The oil was mixed with diesel oil in order to obtain biodiesel. There were four combinations of ratio diesel oil to coconut oil; namely 100% : 0% (mkp0%), 90%:10% (mkp10%), 80%:20% (mkp20%) and 70%:30% (mkp30%.). Mitsubishi L300 diesel engine was used in this experiment by variating engine speed 1000 rpm, 1050 rpm and 1100 rpm with torgue load at 1 kg. At engine speed of 1200 rpm the loads were varied as 1 kg, 1.5 kg and 2 kg. The result shows that by increasing the number of coconut oil in the mixture will reduce engine fuel consumption. Fuel consumption of the mixture will be better compare to the fuel consumption of pure diesel oil. Specific fuel consumption efective (SFCe) of coconut oil-diesel mixture at mkp 10%, 20% and 30% are lower than of pure diesel oil. The reduced SFCe are 1.45 %, 1.71% and 3.57 % at effective power 0.838 PS, 1.98%, 4.31% and 4.31% at effective power 1.257 PS and 1.22%, 3.92% and 7.12% at effective power 1.676 PS. By varying the engine speed, the result also shows that SFCe of the mixture is also lower than SFCe of pure diesel oil.

Abstract

Cow manure can be used as a source of energy and as a solid or liquid fertilizer. An adult cow can produce fases (solid manure) to 23 kg/day and urine (liquid manure) 9 kg/day. Three or four cow is capable to fullfill the dayly needs of cooking fuel for one rural household. Cow manure slurry can also be convert as fertilizer, that is liquid fertilizer which is derived from urine and solid fertilizer originating from the solids. Solid and liquid from cow manure is usually mixed, therefore to make the liquid and solid fertilizer, the liquid and solid masses need to be separated first. Recent separators of fases and urine are are electrical energy driven, so that those kind of device could not be used in the rural areas where the electric grid supply were not available. So that a model of a faces-urine separator of cow manure slurry is utilize which was constructed for manual pressing force. Moreover, through this research It have had created a manual fases-urine separator which only requires one operator. The separator consists of main parts including; lever press, chamber press, fases-urine separation mechanism, the mechanism of loading-unloading, and ajustment mechanism for pressing pressure. This design is capable of performing the separation in a wide range of pressing force and it only requires one operator. Results Show That the model is capable to separate liquid from the slurry as much as 13.9% at a pressing force of 14 kg the which is applied for 18 seconds.
