Abstract

Research about the hydrolysis of l-menthyl acetate catalyzed by lipase enzyme from Candida antarctica recombined Aspergillus oryzae has been observed by in vitro and in silico. The reaction by in vitro method performed with variations time and solvent. The result obtained that lipase enzyme from Candida antarctica recombined Aspergillus oryzae were able to catalyze the hydrolysis reaction of l-menthyl acetate to produce l-menthol. The best result is observed at 16 hours with ethanol solvent, which give % conversion about 13,76%. The research followed by in silico using the docking method,  observed that mechanism between amino acid residues to macromolecules as well as the influence of solvents on such interactions. The residues that involved in the reaction are Glu, Thr, Asp, Gln, Ser, His. The ethanol solvent shows a good interaction with macromolecules by forming hydrogen bonds.

Abstract

In response to the issues of air pollution, temperature, and noise, this project attempts to create an air quality, temperature, and noise monitoring system using Internet of Things (IoT) technology. This system will comprise physical components and a web platform that delivers real-time environmental reports. Users can readily obtain information regarding air quality, temperature, and noise levels via this platform, which takes advantage of the internet's accessibility. This Internet of Things-based device monitors environmental quality in six high-traffic areas in Malang, Indonesia. The system uses various sensors to monitor air quality, temperature, humidity, dust levels, carbon monoxide (CO), carbon dioxide (CO2), and noise pollution in real-time. Data was collected during peak traffic hours, demonstrating the direct influence of car emissions on air quality.  The findings show that some regions' CO and particulate matter levels surpass safe criteria, notably during peak traffic periods, but CO2, humidity, and noise levels are below acceptable norms. These findings highlight the necessity for urban air pollution reduction initiatives. Additional sensor calibration and communication modifications are recommended to increase system accuracy and dependability. This study gives significant insights for local authorities to manage urban environmental quality and safeguard human health.
