        abstract = {In the 21st century with the industrial era 4.0, teachers and students are required to be technology literate. Covid-19 also greatly affected education. Thermochemistry is abstract and difficult to understand, so Project Based Learning (PBL) models are needed. This study developed project-based electronic student worksheets (e-SW) using the Plomp model. Validation results (Aiken's V) were 0.88 and 0.89 (very valid). Practicality results were 89.86\% (small group), 87.21\% (students), and 89.03\% (teachers), all in the very practical category.}
