The objective of this research was to obtain optimum condition of eugenol production from clove oil using a central composite design method. The main process occured in the eugenol production was saphonification and neutralization processes. In order to optimize these processes, the ratio of NaOH/clove oil and temperature were studied as design variables i.e. ratio of NaOH/clove oil=1:2.5-1:3.5 while temperature was varied between 40 and 60oC. The yield of eugenol was considered as the main response in of this experiment. The result showed that the optimum condition was achieved when the temperature and the ratio of NaOH/clove oil were 50oC and 2.75:1, respectively and the yield was 39.17%.<br />

Research on processing of crispy baby tilapia (Oreochromis niloticus) was conducted to obtain type and proportion of flour on this product with central composite design method. This research used 6 types of flour, namely wheat flour, rice flour, potato flour, tapioca flour, corn flour and baking powder. Baby tilapia used for this research were 30-40 day old, 2-3 cm long. Parameters observed were sensory (appearance, odor, taste, texture, overall acceptance) and crispness for the physical parameter. The results showed that only two out of six variables gave big effect on the tested response i.e potato and rice flour. Those two variables were then optimized with central composite design method to obtain the best product. The optimization process demonstrated that the optimum amount of potato and rice flour were 58-60 g (22.16-22.92%) and 40-60 g (15.28-22.92%), respectively.
