Abstract

Pyrolysis which is also called thermolysis will chemically decompose organic matter (biomass) through a heating process without or little O2 or other reagents, where the raw material will undergo a breakdown of the chemical structure into a gas phase. The purpose of this study is as an alternative solution in answering the problem of fuel scarcity in everyday life, & Knowing the amount of activation energy calculated using the Flynn Wall Ozawa method. The biomass used is Dutch teak sawdust obtained from the wood furniture industry in the Tangerang area.The experimental results of pyrolysis of Dutch teak sawdust with round gas opening from experiment 1 to experiment 9 obtained BCO as much as 6.00%, 6.50%, 6.83%, 7.33%, 7.67%, 8 ,83%, 10.17%, 14.33%,16.33%. . While the results of the round gas opening experiment from experiment 1 to experiment 9, BCO was obtained as much as5.67%, 6.17%, 6.67%, 7.17%, 7.33%, 7.83%, 9.67%, 13.83%, 15.83%. The pyrolysis process produces three types of products, namely solid products or charcoal, liquid products (bio-oil) & gas. In our research, the best quality bio oil obtained at temperatures from 548 K to 598 K. The results of bio The oil obtained at this temperature is brownish yellow in color, with an average volume of ± 48 g of bio oil (52.6 ml).
The effect of fermentation time and inoculum amount on total sugar, total acid, total flavonoid, total phenol, and inhibition of alpha-glucosidase activity of red ginger kombucha (Zingiber officinale Roscoe) Euis Filailla; Hani Mulyani; Yati Maryati; Setyani Budiari

Abstract

Kombucha contains organic compounds that are beneficial to the body, namely B complex vitamins, organic acids, and other compounds. The manufacture of kombucha apart from tea is the red ginger platn (Zingiber officinaleroscoe). Red ginger kombucha fermentation was carried out for 0-14 days with the addition of 10% and 20% incoculum. The fermentation time and the amount of inoculum affected decreasing the total sugar content and pH value, as well as increasing the total acid content, total flavonoid, total phenol, and the ability to inhibit the activity of the alpha glucosidase enzyme. Total acid content, total flavonoid, total phenol, and inhibition of alpha glucosidase enzyme activity increased to 0.22 mg/ml, 19.62 ppm, and 56.70%. The decrease in total sugar and pH values reached 60.80 mg/ml and 3.42.
