Environmentally Friendly Phenol Fraction Extraction from Sargassum sp. Using Olive Oil as a Solvent
(Fakultas MIPA Universitas Jember, 2019-11-25)
To minimize the impact of using an organic
solvent to the environment, some oil-based solvent such as
olive oil was proposed as a solvent to extract phenolic
compounds from Sargassum sp. This work is to observe the
effect ...
Experimental Study and Modeling on Supercritical CO2 Extraction of Indonesian Raw Propolis using Response Surface Method: Influence of Pressure, Temperature and CO2 Mass Flowrate on Extraction Yield
(Chemical Engineering Research and Design 153 ( 2020 ) 452–462, 2020-01-01)
It is well-known that propolis shows potential as an antioxidant. A common method to extract propolis is organic solvent extraction which has drawbacks such as long extraction times and solvent residues. To overcome this, ...
Re-design and Exploration of Extraction of Phenolic Compounds from Sargassum Sp using Ethyl Acetate as Solvent
(Fakultas MIPA Universitas Jember, 2019-11-25)
A Marine brown algae, Sargassum sp, is well-known
as a bioactive compound. One of the most important compounds is
polyphenol substance. This research is ongoing to obtain the
highest yield soluble extract of polyphenol. ...
Flame Characteristics of Diffusion of Calophyllum inophyllum Methyl Ester on Mini Glass Tube
(2019-07-04)
Combustion is a chain chemical reaction that is influenced by three factors, namely
fuel, oxidizer, and heat. This study analyzes the effect variations of fuel flow rates (1
ml/h, 2 ml/h, and 3 ml/h) on the laminar burning ...
Experimental Study on Role of Xylose on Furfural Decomposition in Acidic Composition
(2017-12-14)
Sulfuric acid (H2SO4) is broadly used as a catalyst to accelerate hemicellulose and a
considerable part of the lignin components decomposition to generate sugars as intermediate chemicals
for further processing steps. ...
Glucose, Temperature, and Time Reaction Effects: Quantitative Study of Furfural Decomposition
(2017-12-14)
The utilization of biomass as renewable energy is potential to become the fuel and
intermediate chemicals supplier. Furfural is one of important derivative chemical substances
which is obtained from biomass degradation. ...
