Abstract

Glucose is a type of sugar widely used in the food and beverage industry. Liquid glucose can be produced from various starch sources, including cassava. This study aims to determine the effect of cassava types butter and glutinous and the concentration of α-amylase enzyme 0.1%; 0.2%; and 0.3% on the production of liquid glucose through enzymatic hydrolysis. The study used a Randomized Block Design RBD with testing parameters including qualitative starch analysis, yield, and sugar content using a refractometer. Cassava starch was obtained through extraction, precipitation, and drying processes, then hydrolyzed using the α-amylase enzyme. The results showed that the best treatment was obtained in butter cassava with an enzyme concentration of 0.3%, resulting in a yield of 60.44 ± 1.57% and a sugar content of 28.70 ± 2.81 °Brix. Starch analysis showed a color change from dark blue to purple indicating the presence of starch. These results indicate that the type of cassava and enzyme concentration affect the production of liquid glucose.

Abstract

Information and communication technology (ICT) is increasingly used to address urban environmental challenges, yet evidence on its specific roles in Smart Environment initiatives remains fragmented. This study systematically reviews the technologies, functional roles, and environmental outcomes of ICT-enabled Smart Environment development. A systematic literature search was conducted across six academic databases for studies published from 2020 to 2025. Of 1,879 initially identified records, 30 studies met the eligibility criteria and minimum quality threshold and were synthesized thematically. The findings identify the Internet of Things as the most frequently reported technology, complemented by artificial intelligence, cloud/fog/edge computing, digital twins, blockchain, smart grids, and other digital systems. ICT contributes through six interconnected functions: environmental sensing and monitoring, data integration, intelligent analytics, decision support, resource efficiency, and governance support. The main conceptual contribution is an integrative ICT-enabled Smart Environment framework linking ICT enablers, functional roles, application domains, and environmental outcomes. Although the reviewed studies generally report positive contributions, direct and comparable evidence of environmental improvement remains limited. Future research should evaluate integrated ICT architectures using measurable sustainability indicators.
