dc.description.abstract | The increasing demand for environmentally friendly energy has
accelerated the development of alternative biomass-based technologies, one of
which is the pyrolysis of Nypa fruit husk (Nypa fruticans W.) into liquid smoke.
The objective of this study was to evaluate the performance of a multiple
condenser system pyrolyzer in producing liquid smoke efficiently, based on
temperature and pyrolysis duration parameters. The experiment was arranged
using a factorial Completely Randomized Design (CRD) with two treatment
factors: temperature (300°C, 350°C, and 400°C) and pyrolysis time (3, 4, and 5
hours), each replicated three times. The parameters analyzed included effective
capacity, energy consumption, liquid smoke yield, and economic feasibility,
assessed through production cost, Break-Even Point (BEP), Net Present Point
(NPV), and Internal Rate of Return (IRR) calculations. Results showed that the
treatment at 400°C for 5 hours produced the best outcome, with the highest
effective capacity of 0.68 liters/hour, maximum yield of 65.33%, and an NPV
value of Rp22,80,911.7/year at a 5.5% and NPV value of Rp663,451.5/year at
45%. The highest energy consumption was recorded at 281,839.47 kJ/kg under
the same conditions. Economically, the equipment was found to be feasible and
profitable with an IRR of 46.185% and a BEP of 303.342 liters/year. These
findings indicated the multiple condenser system pyrolyzer was a promising
technology for efficient and economical biomass conversion, supporting the
sustainable utilization of organic waste into renewable energy. | en_US |
