IntisariTingginya kebutuhan supply energi menuntut terus dikembangkannya teknologi pengolahan minyak bumi. Salah satu proses penting di dalam pengolahan minyak bumi adalah proses pemanasan, yang secara konvensional dapat mereduksi hasil produksi minyak bumi. Penelitian ini bertujuan untuk membuat pemodelan pemanasan minyak mentah menggunakan energi gelombang mikro di dalam suatu pipa sumur minyak. Teknik pemanasan ini selain bertujuan untuk menurunkan viskositas dan mengurangi jumlah partikel residu, juga untuk meminimalkan biaya produksi. Data sekunder yang diperoleh kemudian dimodelkan dan dianalisa menggunakan parameter NSD (Normalisasi Square Deviation) untuk menentukan kelayakan fungsi. Hasil yang diperoleh bahwa leyakan fungsi untuk pemodelan menunjukkan bahwa temperatur minyak dari permukaan pipa sampai dengan kedalaman sumur menurun secara eksponensial. Temperatur minyak dari pusat silinder sampai ke tepi pipa menurun secara sinusoidal. Untuk sumber gelombang mikro dengan daya 500 W dan waktu 10 s dihasilkan temperatur maksimum 385• C. ABSTRACTDue to the high demand of energy supply, a development in petroleum processing technology is required. One of the important processes in the petroleum processing is the heating process, which conventionally can reduce the oil production. This study aims to create a real-time modeling of crude oil heating process using microwave energy in an oil well pipe. In addition, this heating technique aims to reduce the viscosity and reduce the amount of residual particles, as well as to minimize the production cost. The secondary data were obtained, and subsequently being modeled and analyzed using NSD parameter (Normalized Square Deviation) to determine the feasibility of the function. Modeling results indicate that the temperature of the oil from the surface to the depth of the well pipe decreases exponentially. While the oil temperature from the center to the edge of the cylindrical pipe decreases sinusoidally. The microwave source has a power of 500 W and a maximum temperature produced of 385 • C in 10 s.KATA KUNCI: pemodelan, minyak mentah, pemanasan, energy gelombang mikro,kelayakan model.
