| dc.description.abstract | Usage and utilization of biomass waste such as palm shells one of which
can be done by converting palm shells into energy producer gas through the
gasification process. The producer gas is used as a substitute fuel for diesel
engines-generators for the production of household electricity in the area around
the plant. From the consumer's needs, then the producer gas plant designed
capacity of 3,000 tons / year.
Biomass Gasification is a chemical reaction at a temperature of 800 -
1200 ° C between the biomass with penggasifikasi media by 20% - 30% of the
required stoichiometric combustion. The gasification process produces a gas
producer and a small content of solid particles, ash and tar. Gas producers will be
fuel for diesel engines-generators for electricity production and supply the
electricity needs of the local area which is not got electricity grid for places
difficult to reach. The process steps include the preparation of raw materials palm
shells and air, the formation of producer gas in a fixed bed gasifier types of
down-draft, producer gas purification, and the introduction of gas into diesel
engine-generator set. Purification of producer gas made up the tar content of not
more than 50-100 mg / Nm3, ash content up to 50 mg / Nm3, the size of the dust
is not more than 10 μm, and a gas temperature below 40 oC that does not diminish
the performance and life of diesel engine-generator set.
The factory is planned to stand adjacent to the PT. Agricinal Sebelat
Village area, District Putri Hijau, North Bengkulu and built on a land area of 400
m2 and side by side with diesel as the main generator of electricity providers and
communities with energy supply from gas producers. The factory operates 24
hours per day and 330 days per year with a workforce of 0.05 manhour / Nm3
products. Utility requirements include ground water as much as 10.06 kg / Nm3
products, electricity 0,09 kWh / Nm3 products.
The shape of the company is CV (limited partnership) with line and staff
organizational structure. Systems based on the division of employees working
hours of employees shift and non-shift. The factory is planned to start
construction in early 2017 and be operational in early 2018 with the plant life of
10 years. Plant fixed capital of Rp. 849 922 368, - and the total production cost of
Rp. 544, - / Nm3 products. The feasibility analysis shows that the ROI before tax
after tax 45.42% and 34.06%. POT 1 year before tax of 1.8 years and 2.27 years
after tax, BEP 43.47%, 32.04% and DCF SDP amounted to 32.33%. Based on the
parameters above, the plant is worth considering for the realization of its
development. | id |
