The study of the effect of three varieties of bamboo and pyrolization temperature of 400 degree C,500 degree C,600 degree C,and 700 degree C on the isothermal adsorption of H,the adsorption of chloroform and the electrical conductivity of charcoal have been carried out.The study was aimed to the determine characteristic of charcoal to be measured of the adsorption of isothermal ion H+ by using acid solution of acetate 0,1 mole the adsorption of chloroform and the electrical conductivity.The research result shown that the temperature of pyrolization excelsior,the adsorption isothermal ion H+ and the chloroform exelsior but the electrics conductivity progressively lower for all bamboo types.The best of isothermal adsorption.Of ion H+ andong charcoal was 3,87 x 10-6 mol/liter/g at the temperature pyrolization 600 degree C with value of K1 = 0,03351,petung charcoal was 1,25 x10-5 mol/liter/g at the temperature pyrolization 400 degree C with value of K1 =0,02888 and the korea charcoal was 5,34 x 10-6mol/liter/g at the temperature pyrolization 700 degree C with value of K1=0,02849 respectively.The best of chloroform adsorption for the andong caharcoal 262.0%,the petung charcoal 180.5% and the korea charcoal 125,7% at temperature pyrolization 700 degree C.The best of the electrical conductivity for the korea charcoal and the andong charcoal was ranged beetwen 0,37-2.54 MQ.

The study of additional effect of butylated hydroxy toluene (BHT)on extraction quality of crude,degummed,and bleached castor oil has been conducted.This study was aimed at elaborating the effect of BHT addition on every castor oil processing step e.g crude oil extraction,oil degumming,and oil bleaching.Such results were compared to those without BHT addition.To know the quality reduction of these oil extraction some parameters were treated namely FFA level and peroxide value.The BHT concentrations applied were 0.1 and 0,2% and the effect of these addition were monitored during 4 hours with 1 hour testing interval.The result shows that FFA level and feroxide value on bleaching step were lower than those of crude oil extraction and degummuing process.However antioxidant of BHT addition was able to reduce FFA and peroxide value compared to those wihout BHT and these data is very beautiful to know earlier if the oil processed can be processed better further and to prevent unwanted product.

Clove leaf oil is one of the eugenol and beta-caryophylene source essential oils commonly use for chemicals,farmacies,fragrance,and food inductries. The problem of clove leaf oil is poor quality i.e. low eugenol content and dark brown colour,result in price low price.One alternative of increasing its quality and value is by chemical deterpenation method. This method include aging period treatment after reacted with sodium hydroxide for 12 and 24 hour. Eugenol and beta caryophilene content was analised by gas chromatogrphy.The eugenol content extracted from this method was compared with imported eugenol products i.e.containing 85%-99,2% with 70,09%(v/v) yield,aging of 12 hour result in eugenol content 80%-84% and 50.22% (v/v) yield.This method also result in beta caryophylene extrec as side product, aging of 24 hour result in the highest content of beta caryophylene i.e. 80%-85% with 25,22%(v/v)yield,whereas 12 hour aging result in beta caryophylene content of 62%-64% and 24,01% (v/v) yield.

High fiber tofu pressed cake a as by producton manufacturing tofu is posibble to used for raw material on preparing alternative functional food ingredient.This reasearch was designed to study the manufacturing of high fiber flour from tofu pressed cake.The flour flow process chart described as follow.The first flour processed from tofu fresh cake which then dried on drum dryer prior to be milled to become 60 mesh flour.The second one processed from tofu fresh cake which then pressed,sterilized,followed by soaking on sodium metabisulfit 3% for 40 minutes,pressing,freezing,drum drying,and milling to become60 mesh flour.The third one processed from tofu fresh cake which then pressed,sterilized,followed by soaking on sodium metabisulfit 0.1% for 40 minutes,pressing fermentation using neurospora sitophila mould (2,5% for 24 hours),freezing,drum dyring, and milling to become 60 mesh flour.The flour was then analyzed for physico chemical,functional and sencory properties.Soaking in sodium metabisulfit 3% for 40 minutes before drying increase whiteness of flour.Fermentation with neurospora sitophila improve protein digesbility but lower the whitenes.Soaking in sulfit and fermentation increased the flour solubility dietary fiber and descreased unsoluble dietary fiber.The fiber total content in the flour ranged from 46.75 up to 56.24% (db)and the consumption of 25 g of the flour will contribute 50% of the fiber RDA (Recognice Daily Allowance).
