| dc.description.abstract | Waste can be defined as waste substances or materials resulting from a production
process, both industrial and domestic. The focus of this research examines the
chemical components of organic solid waste. Chemical properties consist of
structural and non-structural components. Therefore, the aim of this research is to
determine the test results of the chemical components analyzed including the
structural chemical composition including holocellulose, α-cellulose,
hemicellulose, ASL (Acid Soluble Lignin) and AIL (Acid Isoluble Lignin), as well
as the chemical composition of non- structural such as extractives with ethanol
benzene 1:2 and ash content. The samples tested were durian peel, bamboo leaves,
vegetables and mahogany litter. The results of the research show that there are
variations in the values of the chemical properties of organic solid waste. The
highest lignin content of ASL is found in vegetables at 7.85% and the lowest in
mahogany litter at 3.19%. The highest AIL lignin content was found in mahogany
litter at 16.15% and the lowest in vegetables at 10.68%. The highest level of
holocellulose was found in durian skin at 58.92%. The highest alpha-cellulose
content was found in vegetables 36.36%. The highest hemicellulose content is
found in bamboo leaves, namely, 27.33%. Bamboo leaves have the highest
extractive substance value in alcohol-benzene 1:2, namely 9.23%. The ash content
of vegetables has the highest value, namely 16.35%. | en_US |
