Abstract

Heat is defined as the heat energy possessed by a substance. In general, to detect the presence of heat possessed by an object that is by measuring the temperature of the object. The size of the required heat of an object (substance) depends on three factors: the mass of a substance, the type of substance (specific heat), and temperature changes. Measurement of the amount of the heat of reaction is absorbed or released in a chemical reaction with an experiment called calorimetry. While the tool used to measure the amount of heat (calorific value) exemptions for the calorimeter. Calorimeter is divided into two types, namely the bomb calorimeter and calorimeter solution. Kerosine (petroleum) is apetroleum fraction having a boiling area around 174-275oC. Kerosene (kerosene) is a mixture of alkanes with chain C12H26-C15H32. In this research study on the effect of stirring on the performance in the bomb calorimeter measurement of calorific value of petroleum. Power calorimeter is turned on, then fill with kerosene bomb tube of 500 ml, and as much as 5 liters of water tube and then insert the variable T1 (the sample temperature is 55° C, the water temperature of 33oC), variable stirrer (10 rpm, 20 rpm and 30 rpm) , Subsequently turn the heater so that the sample can reach T1, when the sample temperature and the water temperature has reached T1, turn off the heater and press lighters, observe the changes to the last two constant variables to record three times (this temperature as T2). The calorific value obtained reaction among others 15.270,96 kcal/kg, 10.115,07 kcal/kg, and 5.967,17 kcal/kg.. Best is the second experiment to produce a reaction calorific value 10.115,07 kcal/kg.. Keywords: bomb calorimeter, kerosene, heating value
