Abstract

A research about utilization of waste corncob (Zea may L.) as active charcoal in reduction ammonia, nitrite and nitrate levels on industrial tofu liquid waste using dye technique have been researched. The purpose of this research to know reduction levels of industrial tofu liquid waste from some parameter is ammonia, nitrite and nitrate by using 2 variations is contact time and pH tofu liquid waste. The percentage yield of research to show of reduction ammonia, nitrite and nitrate levels at the optimum contact time 10 minute and the optimum pH 6 that is 51,29%, 31,93% and 58,71%. And then analyzed of data by using ANOVA test to know Fcount influence of the contact time of active charcoal to reduction ammonia, nitrite and nitrate levels on industrial tofu liquid waste that is 2,4891 less than Ftable 3,00. It is stated that is no significant effet on the reduction ammonia, nitrite and nitrate levels of industrial tofu liquid waste by using variation contact time active charcoal. While Fcount influence of optimum pH industrial tofu liquid waste to reduction ammonia, nitrite and nitrate levels on industrial tofu liquid waste that is 5,7168 more than Ftable 2,07. It is stated that is a significant effet on the reduction ammonia, nitrite and nitrate levels of industrial tofu liquid waste by using variation optimum pH industrial tofu liquid waste.

Abstract

Determination of amino acid essential’s content (phenylalanin, threonin, tyrosin and valine) on turtle eggs and chicken eggs. Turtle eggs and chicken eggs are a high animal protein source and easy to obtain. This research has been carried out by categorizing of turtle eggs and chicken eggs by size and continued analysis of water content by Methods of Gravimetry, analyzes protein content total by the Method of Kjeldahl and analysis of the levels of essential amino acids with Method of HPLC (High Performance Liquid Chromatography). In this study, the researcher found the water content in the mix (large, medium and small) is 73,1891% and mixture of chicken eggs of different size is 73,1820%. Results of total protein content with used Kjeldahl method mixture based on the size of turtle eggs is 9,3114% and mixture chicken eggs is 10,2691%. Results of the amino acid content with used HPLC (High Performance Liquid Chromatography) method on a mixture of turtle eggs is Phenylalanin 1,69%, Threonin 1,16%, Tyrosin 2,46% and Valine 1,46%. Mixture of chicken eggs is Phenylalanin 0,30%, Threonin 0,61%, Tyrosin 1,03% and Valine 0,55%
