It has been analyzed the result of propellant research with variable aluminum content to the combustion energy output . Measurement of the amount of combustion energy carried by the bomb calorimeter. Propellant sample was made by mixing HTPB and aluminium for 15 minutes, adding fine AP for mixing 20 minutes, adding coarse AP for mixing 50 minutes. After stirring ends, the TDI was added and stirred for 15 minutes . Aluminum content in the propellant varies from 8 % to 18 %w . The resulted combustion energy is 2885 cal/g to 3750 cal/g . In 18 % of Al content, burning energy begin to reduce . This reduction was largely caused by burning sample together with the erosiving sample ABSTRAKTelah dilakukan analisis hasil penelitian propelan dengan variabel kandungan aluminium terhadap hasil energi pembakaran. Pengukuran besarnya energi pembakaran propelan dilakukan dengan bomb calorimeter. Sampel propelan dibuat dengan mencampur HTPB dan aluminium selama 15 emnit dilanjutkan pencampuran dengan AP halus selama 20 menit, lalu dengan AP kasar selama 50 mrnit. Setelah pengadukan berakhir maka ditambahkan TDI dan diaduk selama 15 menit. Kandungan Al di variasi dari 8% hingga 18%. Energi pembakaran yang dihasilkan adalah 2885 kal/gr hingga 3750 kal/gr. Pada 18% Al energi pembakaran mulai menurun. Penurunan ini diakibatkan oleh sebagian besar sampel yang terbakar sama dengan sampel yang mengalami erosiv.
