Abstract:
Crispy-fried onions is a popular garnish and flavour enhancing produced by deep
frying. Home based industries producing crispy-fried onions use a traditional
conventional stoves for heating oil. Since conventional stoves fuel by biomass,
such as woods, deep frying process releases toxic fumes that compraises small
particles, carbon monoxide, and other noxious fumes. Therefore, replacement
the conventional stove stove in crispy-fried onions home-based industries by the
gasifier stove is necessary because the gasifier is healthier than the traditional
stove.
Home-based industries adopt the healthy stove technology for the traditional
stove replacement as long as the stove is low-priced fuel intake, easily operated
and simply constructed. This study is aim to evaluate energy cost for red onions
frying in a home based industry that is production cost component. At the
beginning of frying process, initial amount of woods was placed in gasifier stove,
than certain amount of wood was added into the gasifier stove periodically for 1
hour.
The result shows the gasifier stove requires 0,6 kg of woods / 1 kg fried onions /
hour only while the traditional stove requires 1 kg of woods / 1 kg fried onions /
hour. These numbers means the energy cost of the healthy stove is lower than
the the traditional that effect on variable cost reduction from Rp. 655.000,- to Rp
462.000,-.
