Effect of temperature and time on alkaline pretreatment and alkaline microwave-assisted pretreatment on banana stem composition

Abstract

is one of the largest banana-producing provinces in Indonesia. Banana stems have cellulose content of 50-60%, hemicellulose of 20% and lignin of 5%, so that banana stems can be used as a source of lignocellulose biomass [1]. According to the Central Bureau of Statistics and the Directorate General of Horticulture, in 2015-2019, the harvest area of banana plants in Indonesia reached 105,801 ha [2]. In addition, based on data from the Central Statistics Agency in 2021, banana plant production in Indonesia came to 8,741,147 tons, while South Sumatra Province itself got 354,143 tons, which is the 6th province that produces the most banana plants in Indonesia [3]. The large area of banana crop harvest and production causes an abundance of banana stem waste, so it has excellent potential to be used as raw material for various processes, one of which is the delignification
