Betung bamboo (Dendrocalamus asper) is one type of bamboo that is often utilized as a structural raw material through a drying process to increase its stability. This study aims to calculate the amount of drying energy consumption using a double pass type solar dry oven with a simple formula approach in order to better estimate the energy used for drying. There are three types of material capacity experiments, namely 25%, 50% and 75% capacity with the number of bamboo slats used respectively 6, 12, and 18 slats. The observation results obtained the highest average temperature of 60.22 ± 11.9? and the lowest average RH of 19.5 ± 15.5%. The final moisture content after ten days of drying in the 75%; 50%; 25% capacity experiment was 8.98%; 11.62%; and 8.69%. The drying speed on the first day of the 75%; 50%; 25% capacity experiment was 0.86%; 1.00%; 1.02% respectively and tended to have the same pattern on the following days. The calculated energy consumption approach is the accumulated energy to heat the bamboo (Q1) at 25%; 50%; and 75% capacities of 714.08 kJ; 826.16 kJ; and 1392.07 kJ respectively. Also, the accumulated energy to weaken the water bonds in the bamboo (Q2) at 25%; 50%; and 75% capacities of 31.59 kJ; 41.65 kJ; and 84.31 kJ respectively. In addition, there are no drying defects such as shape defects and surface defects during drying so that the oven used is very safe for drying.
