Environmentally Friendly Phenol Fraction Extraction from Sargassum sp. Using Olive Oil as a Solvent
Ratnasonia, Samantha Githa; Palupi, Bekti; Fitriana, Meta Rizki; Rahmawati, Istiqomah; Fachri, Boy Arief (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 on Role of Xylose on Furfural Decomposition in Acidic Composition
Setiawan, Felix Arie; Fachri, Boy Arief; Rahmawati, Istiqomah; Palupi, Bekti; Rizkiana, Meta Fitri; Susanti, Ari (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. ... -
Extraction of Phenolic Compound from Sargassum Sp. in Ethanol: effect of Particle Size, Extraction Time and Ratio Substrate to Solvent on The Yield of Phenol
Pujianto, Slamet; Rahmawati, Istiqomah; Sari, Puspita; Oktavianawati, Ika; Fachri, Boy Arief (Fakultas MIPA Universitas Jember, 2019-11-25)Sargassum Sp., a part of brown algae, traditionally is used as animal feed. In spite of this, Sargassum containing phenolic compound which shows a promising as a natural antioxidant feedstock. This work is to extract ... -
Glucose, Temperature, and Time Reaction Effects: Quantitative Study of Furfural Decomposition
Rahmawati, Istiqomah; Fachri, Boy Arief; Setiawan, Felix Arie; Palupi, Bekti; Rizkiana, Meta Fitri; Susanti, Ari (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. ... -
Re-design and Exploration of Extraction of Phenolic Compounds from Sargassum Sp using Ethyl Acetate as Solvent
Altafdilah, Dyah Mufidah; Fitriana, Meta Rizki; Rahmawati, Istiqomah; Palupi, Bekti; Fachri, Boy Arief (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. ...
