Distillation of Agarwood Oil (Aquillaria sp) using Photovoltaic Methods

: The use of solar light is currently used as one of the renewable energy by utilizing sunlight, or commonly called photovoltaic (PV). One of the technologies related to the application of solar panels to energy by converting sunlight into electricity is called photovoltaic. The amount of solar energy that can be absorbed depends on the cell size and absorption of solar cells on sunlight. Solar panels are known as WP (Watt peak) where this amount is the maximum power produced by each panel unit with a capacity of 100 watts/hour, size 1200 mm x 550 mm with a thickness of 35 mm. The battery used is 12 Volt 200 Ah, and the heater used is 2000 Watt. Agarwood crust is obtained from the Aquillaria malaccensis tree, which is then soaked for 14, 16, 18, 20 and 22 days respectively. The best results of soaking are at 14 days, during which the immersion process has expanded and finally broken, so that water enters the cell wall through diffusion and increases turgor pressure. Soaking water becomes more acidic over time and damages the cell wall. This causes the process of increasing cell wall destruction. However, a longer immersion time causes more oil content to be wasted into soaking water. It was concluded that the most suitable immersion time for extracting agarwood oil was 14 days. The results showed that high oil yield was obtained from oil extracted with a 10 hour hydro distillation sample (0.44% analysis water content). Analysis of chemical compounds using GC-MS showed a typical compound of agarwood namely Guaiol with the highest value 4.10% (GC-FID) and 1.95% (GC-MS). Guaiol was used as a parameter to determine the quality of essential oils produced from the distillation process that has been carried out because the area produced from the test results has an area greater than other components contained in essential oils.
