Analisis Prestasi Lampu Petromax Berbahan Bakar LPG
Abstract: In order to decrease
subsidy cost of kerosene consumption, Indonesian government right now proposes
to convert kerosene to LPG. Consequently, the price of kerosene is expensive in
society. LPG can be alternatively used as fuel for the petromax lamp. The use
of LPG for the petromax lamp fuel is strongly recommended for sidewalk food
sellers as source of light at night if the electricity source is not available.
Therefore, it is important to investigate some advantages of the use of LPG as
replacing of kerosene for the petromax lamp. The performance of the petromax
lamp using LPG as fuel had been carried out with parameters: rate of fuel
consumption and light intensity, representing to the need of energy
consumption. In the view of economic, the performance of the petromax lamp
using LPG was also compared with the performance of petromax lamp using
kerosene. The results show that the use
of LPG is more clearly efficiency than those of use of kerosene. The fuel
energy needed by the petromax lamp to generate lighting is around 224.87MJ/h
for kerosene and 213.24 MJ/h for LPG. The energy consumption of LPG is
decreased by a factor of 1.05. Economically, the comparison of the price
between kerosene and LPG is very significant. The price of kerosene consumption
per hour was approximate Rp.941.00, whereas the price of LPG consumption per
hour was approximate Rp. 368.00. This shows that if the petromax lamp is
operated using LPG for 6 h, the seller foods can save around of Rp 3,438.00.
