Abstract

Imperata cylindrica, commonly known as alang-alang, is a fast-growing, abundant, and underutilised grass often considered a weed. However, its high cellulose content makes it a promising lignocellulosic biomass for renewable glucose production. This study explores the synthesis of glucose from Imperata cylindrica through acid hydrolysis, with the aim of utilizing this low-cost biomass as a sustainable raw material for bio-based products. The hydrolysis process was investigated using two main variables: hydrolysis time (1, 1.5, 2, 2.5, and 3 hours) and acid concentration (1%, 1.5%, 2%, 2.5%, and 3%). The resulting hydrolysates containing glucose were analyzed using a refractometer, UV-Vis spectrophotometer, and further optimized using Response Surface Methodology (RSM). The highest glucose content obtained by refractometer was 6.5%, while RSM predicted a maximum of 6.49%, and UV-Vis analysis showed 6.34%. All optimal results were achieved under the condition of 2.5 hours of hydrolysis time and a 3% acid concentration. These findings highlight the potential of Imperata cylindrica as a viable and sustainable feedstock for glucose production through acid hydrolysis, contributing to the development of alternative bio-resources.

Abstract

The unsafe and improper use of pesticides among farmers can pose various health and environmental risks. In order to increase farmers’ awareness and understanding of the dangers as well as the safe use of pesticides, a community service program was carried out in Giripurno Village, Bumiaji District, Batu City. This program included socialization and training involving 17 local farmers. The activities covered the delivery of materials on types of pesticides, their negative impacts, and correct and safe application techniques. An evaluation was conducted through pre-tests and post-tests to measure the improvement in participants’ knowledge. The results showed a significant increase in farmers’ understanding of pesticide hazards and their safe usage. This program is expected to help farmers adopt safer and more sustainable agricultural practices, while also protecting their health and the surrounding environment.
