Kinerja Bom Kalorimeter Pada Pengukuran Nilai Kalor Biosolar (Performance of Bom Calorimeter to Measuring Calorific Value of Biosolar)

Abstract

Heat engine is defined as energy heat possessed by a substance.In general for detecting the presence of heat engine owned by an object namely by measuring temperature the package.Big or small the heat engine needed an object ( a substance ) dependent on 3 factors: a mass of substances, a kind of a substance ( heat engine among, and changes in temperature.Measurement of the amount of heat engine reaction absorbed or released at a a chemical reaction with experiment called kalorimetri.While an instrument used to measure the number of heat engine ( a value calories ) who were freed is the calorimeter.A kind of the calorimeter divided into 2, namely the calorimeter bombs and the calorimeter solution.Biosolar is a mixture solar with oil vegetable obtained from oil palm or crude palm oil ( cpo ).According to balai engineering design and technology system biosolar having value heat engine of 37000 kJ/kg.To research will study of the influence of temperature of the performance of the calorimeter bomb on measuring value heat engine biosolar. The calorimeter brought power , and fill tube bomb with biosolar as many as 500 ml , and water tubes as many as 5 litres of then inserting variable t1 ( temperature sample 40oc , this water temperature 30oc ) .Next life heater to sample can reach t1 , when the temperature sample and temperature water has reached t1 , turn off heater and press the grow , last observe a change to two variables recorded ( temperature this as t2 ) .Value heat engine reaction obtained among others 36082,28 kJ/kg, 36208,87 kJ/kg, 36335,48 kJ/kg, 36462,09 kJ/kg, 36588,69 kJ/kg. Experiment was best to the second with produce values heat engine reaction 36588,69 kJ/kg . Keywords: bomb calorimeter, Biosolar, heating value. Email :
