Green coconut fiber was treated by supercritical CO 2 with the aim to enhance hydrolysis of
its enzymatic cellulose. To this end, different static conditions of CO 2 contact times (3 and 5 …

Sulphuric acid hydrolysis of coconut coir under case I (time: 2–10 min; temperature: 160–
240° C; acid concentration: 0.2–0.7% w/w) and case II (time: 10–60 min; temperature: 100 …

Coconut husk (CCH) as an abundant agricultural waste in Indonesia has the potential to be
utilized for sugar production, which is the intermediate product of biofuel. In this study …

The purpose of this research is to study the effect of concentration and temperature on the
cellulose and lignin content, as well as the reducing sugars produced in the enzymatic …

Isolation of vanillin from lignin extracted from coconut husk is presented in this study.
Phosphoric acid (20%) is employed to precipitate the lignin from the black liquor produced …

Background: Coconut husk has the potential to be used as a source of alternative energy
such as biofuel. Its high lignin content, however, poses difficulty to this use. Objective: To …

Studies about renewable energy are evolved continuously to decrease the needs of fuel oils
that were diminished. One of the alternative energy sources that can be evolved is …

This study aims to determine the effect of mass variation of Saccharomyces cerevisiae
(baker's yeast) and determine the optimum time required for the bioethanol fermentation …

Rice processing produces two major types of wastes which are rice husk and rice straw. The
husk is the outer coat of paddy grain while the straw is the dry stalks of paddy. Burning in …

Background: Lignocellulose resources are abundant, but the utilization rate is very low, and
wheat straw is one of them. The main reason is that the compact structure of lignin limits the …
