Abstract

Soil is an essential medium for almost all plants. Temperature and moisture in the soil become one of the factors that affect plant growth. Unbalanced or unfavorable soil conditions will adversely affect the plant. Therefore, soil conditions, including temperature and moisture, must be monitored to maintain plant health. Forecasting can be used to find out the soil condition in the future so that strategies can be prepared to deal with these conditions. This forecasting is carried out based on existing soil temperature and moisture data, which is then processed using the exponential smoothing method and mean absolute percentage error as a reference for the error rate or accuracy of the forecasting. The application of these methods succeeded in producing forecasting with very good overall accuracy.

Abstract

Engineering education has gained significant importance in the 21st century due to its integration of essential technological literacy needed in our rapidly changing world. Laboratories, including virtual laboratories, allowstudents to apply theoretical knowledge practically. Virtual laboratories have emerged as innovative tools that offer increased accessibility and flexibility. This study reviewed 29 peer-reviewed journal articles indexed in Scopus and published between 2018 and 2023 on the use of virtual laboratories in engineering education. The research employed a systematic literature review framework, utilizing PRISMA for article selection.The findings indicate that virtual laboratories provide numerous benefits, including cost-effectiveness, flexibility, safety, and accessibility. They boost student motivation, engagement, and the ability to apply knowledge while effectively enhancing conceptual understanding and practical skills. Virtual laboratories support the development of pedagogical skills and promote careers in engineering by offering a comprehensive and inclusive learning environment.Despite these advantages, challenges likelimited interactivity, restricted content, and technical issues persist. Virtual laboratories are valuable supplements to traditional laboratories, providing an economical means to explore phenomena and offering a safe space for experimentation. Educators should consider the benefits and limitations ofintegrating virtual laboratories into their curriculum. This study aims to deepen the understanding of virtual laboratories in engineering education, advocating for their broader adoption as an innovative tool with a positive impact.
