Kinetika Co-Pyrolysis Cangkang Kelapa Sawit dan Low Density Polyethylene (LDPE) Menggunakan Oven Microwave dengan Daya 600 Watt

The need for fossil energy in Indonesia is increasing in line with the growth
rate of human life. The increasing need for fossil energy will have an impact on the
availability of these energy sources. Indonesia is the second largest oil palm
producing country after Malaysia. The palm oil industry will generate solid waste
from the palm oil processing process. The issue of waste in Indonesia cannot be
denied, especially plastic waste, which continues to grow every day. Themethod
Microwive Co-Pyrolysis using this waste treatment is an alternative. The purpose
of this study was to determine the kinetics characteristics of micowive co-pyrolysis
from a mixture of biomass (oil palm shell) and plastic Low Density PolyEthylene
(LDPE)with 600 Watt power.
The kinetics analysis uses themethod thermogravimetric analysis
(TGA)which includes maximum temperature, heating rate, mass loss rate, and
activation energy. Biomass mixtures with LDPE varied at 100: 0, 50:50, and 0:
100. All variations use 50% amaterialbsorber of the total sample mass. Data was
collected for 1 hour and recorded per second.
The results showed that the material content of the test material affected the
maximum temperature, heating rate, mass loss rate and activation energy. The
composition of LDPE-shells was 50:50 and 0: 100, the maximum temperature
decreased by 5.1% and 44.26%, the heating rate decreased by 37.51% and 70.88%,
the mass loss rate decreased by 46.84 % and 64.75% of the 100: 0 variation or pure
shell. The activation energy value of the 100: 0 LDPE-shell composition had the
lowest value while the 0: 100 variation had the highest value. These results indicate
that the Co-Pyrolysis solid waste from oil palm and plastic waste has different
effects when the two materials are mixed.
