Manusia mampu melakukan sesuatu sesuai dengan apa yang ada dalam pikirannya, seperti kata Rene Descartes: Cogito Ergo Sum. Segala sesuatu yang ada di dalam pikiran berbentuk bayangan, yang dikenal dengan mental imagery. Manusia menghadapi suatu masalah tergantung pada kemampuan membayangkan faktor-faktor yang berhubungan dengan masalah tersebut. Sementara itu, literasi matematika menuntut kemampuan untuk menerapkan matematika dalam memecahkan masalah sesuai dengan konteks kehidupan. Artikel ini menganalisis peran mental imagery dalam membangun literasi matematis. Metode penelitiannya adalah tinjauan literatur sistematis, terhadap buku atau artikel penelitian terdahulu, untuk menganalisis konsep mental imagery dan literasi matematis serta hubungan keduanya. Pembaca akan mendapat asupan teoretis, yang menjadi landasan ilmiah untuk mengoptimalkan peran mental imagery dalam pembelajaran matematika atau tindakan pendidikan modern.

Abstrak. Learning is currently transitioning to digital learning. This encourages teachers to create a learning environment that can support students’ learning. The results of PISA 2018 show that students' mathematics learning in Indonesia is not good. This is partly due to the low interest in learning mathematics. Therefore, efforts are needed to increase students' interest in learning mathematics. One of them uses mathematical modeling learning. The purpose of this study was to analyze how the influence of learning mathematical modeling on students' interest in learning. This study used a design research approach focused on the retrospective analysis stage with quantitative and qualitative analysis. The results showed that learning mathematical modeling had a positive effect on students' interest in learning. In addition, students' interest in learning can also be shown when learning takes place. Students participate actively during learning activities, ask questions when needed help, and collaborate with each other. It is hoped that with this research, teachers can use the mathematical modeling learning environment as a learning reference.

The degradation of green open spaces and the phenomenon of deforestation in Indonesia has increased discomfort in the region. Furthermore, if allowed to continue, the increase in temperature caused by greenhouse gases worsens the situation. Increased temperature and reduced air humidity are related to thermal stress, affecting human comfort and health. Thermal stress is measured based on the Temperature Humidity Index (THI), which calculates temperature and relative humidity variables. This study analyses THI projections under climate change scenarios RCP4.5 and RCP8.5. This study uses statistical downscaling and bias correction of Quantile Delta Mapping (QDM) to equalize the local climate. This study is divided into four 20-year periods from 2021 to 2100 to evaluate THI changes in future projections. Based on the study results, it is known that from 2041-2060, several big cities in Indonesia experienced an increase in THI and were included in the category of 50% of the population feeling uncomfortable. THI increased in the third and fourth periods. Areas that experienced a significant increase in THI were urban areas that lacked green open land and were densely populated. Surabaya City and Madura Island are the areas with the highest THI index.
