Abstract

The study of diversification of citronella and clove oils in mosquito repellent newspaper ink have been done. The obyective of this study were to observe the effect of stirring speed and carbon black adding on viscosity in the repellent ink. The ink manufacturing was made by adding of ink and citronella oils- clove oils in ratio 4:1, variation of carbon black 12.5%; 25%; qnd 37.5% of ink weights. Furthermore the mixing of ink with stirring speed 300, 400, 500 rpm for 0 hour and 24 hours. The results of this study indicate that the best of newspaper ink formula was using ink, citronella-clove oils in ratio of 4:1, carbon black 37.5% and stirring speed 300 rpm has of viscosity 300dPa.s and 450dPa.s in 0 and 24hours respectively.
