Abstract

Covid-19 became a global pandemic in 2020 and has multiple impacts on the economy, social, culture, food systems, and also the environment, especially on tropical forest cover in small island. This study aims to determine the impact of the Covid-19 pandemic on the forest cover of small populated islands. Using remote sensing and geographic information system technology based on high-resolution satellite imagery from google earth imagery, land cover was observed in 2018, 2020, and 2023. This study found that during the 2020 pandemic, tropical forest cover on small populated islands has decreased. Mansinam's forest cover decreased by 4.3%, bare land increased by 80.6%, agricultural land increased by 75.3%, and shrubs increased by 54.9%. Another important finding is that 78.9% of the total deforestation was due to forest conversion to bare land and agricultural land. Land and forest utilization on small islands will increase when accessibility is limited, especially during the pandemic. Future studies will be on the structure and composition of species in locations that experienced deforestation during the pandemic and detailed studies related to changes in the occupations of Mansinam people due to the pandemic that have a relationship with forests.

Abstract

The National Education Goals play an important role in realizing the nation’s ideals through various learning resources and media accessible to students in schools. Strong learning motivation serves as a fundamental basis for developing students’ potential to become faithful, morally upright, and responsible individuals. One way to enhance learning motivation is by providing engaging learning media, such as glossaries that help students better understand scientific terms.  This study aims to examine the effect of illustrated glossaries on students’ learning motivation in the topic of the plant world. A quasi experimental method with a pretest-posttest control group design was employed. Two classes participated in the study: an experimental group that used illustrated glossaries to assist in understanding scientific terms and a control group that did not use any glossary, both using the same biology textbook. Data were collected using a learning motivation questionnaire measuring eight indicators, including perseverance, persistence, interest, independent work, boredom with routine tasks, maintaining opinions, determination, and problem solving enthusiasm. The results indicate that the use of illustrated glossaries significantly increased students’ learning motivation compared to those who did not use them. Motivation indicators in the experimental group ranged from high to very high categories. In conclusion, illustrated glossaries effectively enhance students’ learning motivation in plant world material. It is recommended that illustrated glossaries be implemented across various educational levels and fields to support accurate and consistent scientific terminology, helping students keep pace with scientific advancements.
