Abstract

The sun is a source of alternative energy that is not polluting and can be used either directly or indirectly. Based on that we can use the energy of sunlight to heat water system with thermosiphon effects, by using a means of collecting solar radiation (solar collector) which absorbs the radiation and convert into heat through the absorber plate and forwarded to a pipe containing water. Absorber plate layer affects the effectiveness of the absorption of solar heat collectors. Solar collector is analyzed in the variation of the absorber plate layer on the parallel pipe, absorber plate is positioned above and below the parallel pipeline. Experiment conducted starting at 9:00 am to 15:00 pm. Effectiveness of heat absorption is obtained by using a layer under the parallel pipe plate at 11.2%, while for the layers above and below the plate parallel pipelines reached 17.8%. Differences in the efficiency of the obtained results that the use of layers above and below the absorber plate parallel pipeline more effectively.

Abstract

In this study, waste of bagasse and wood charcoal was converted into charcoal briquettes to be used as an alternative fuel. The bagasse and wood charcoal were selected as raw material to produce briquette due to these two materials was abundantly available and because they have not been used in any application. Moreover, the use of them as briquette and alternative energy will reduce the accumulation of waste that causes environmental pollution. Analysis of proximate test and heating value test showed that the percentage of moisture content of bagasse briquettes withdammar as adhesive is 3.36 to 1.47%, the amount of volatile matter is 36.91 to 30.15%, the ash content is 8.05 to 6.10 % and heating value is 3683.68 to 4520.88 kJ / kg. As for the charcoal briquettes was obtained that percentage of moisture content is 3.25 to 1.36 %, content of volatile matter is 34.55 to 26.53%,ash content is 6.36 to 5.37%, and heating value is 3934.84 to 5274.36kJ/kg.
