| dc.description.abstract | Crude coconut oil is one of the industrial products which have been known
and used as raw material for public consumption industry, such as coconut oil and
cosmetics. Since this products are widely used by the public, crude coconut oil
products are required to meet quality standards set by the government. Therefore, the
issue of quality becomes a major concern in the industrial processing of crude
coconut oil. This study was conducted to improve the quality of crude coconut oil in
PT. Multi Nabati Sulawesi (Luwuk). The method used is the design of experiments
using the Taguchi method with L18 orthogonal matrix. Optimization is done for two
responses, namely the content levels of FFA (free fatty acids) and the levels of oil
content in copex (bungkil), and both of the responses have the characteristic quality
of the smaller the better. Factors examined include drying method with two factor
levels, length of storage, the moisture content of raw materials, oil content of raw
materials, temperature of pre press machine, temperature of final press machine,
ampere of pre press machine and ampere of final press machine with each have three
factor levels. Results obtained from this study are the most optimal setting of these
factors, as follows: drying sunrise (using sunlight), 0 months length of storage,
moisture content of raw materials is 7%, oil content is 63%, temperature of pre press
machine is 90oC, temperature of final press machine is 55oC, ampere of pre press
machine is 60A and ampere of final press machine is 40A. The study is limited by
cost factor, and therefore it is suggested to develop a more comprehensive work
supporting by taguchi loss function. | en_US |
