This study aims to produce products, describe logistical and empirical feasibility, and determine the effectiveness of using the E-worksheet based on the Project Based Learning (PJBL) model using Bengkulu’s traditional foods to improve the ability to solve mathematical problems in rounding material for grade IV elementary schools. This research is a Research and Development (R&D) study. The model used in development is the ADDIE model. The subjects in the study were students of SDN 52 Bengkulu City, totaling 26 students in class IV B as the control class, and 26 students in class IV C as the experimental class. The instruments used in this study were interview guidelines, questionnaires, and problem solving tests in the form of essay questions through pretest and posttest. To measure the effectiveness of understanding the concept, tests were carried out twice, namely before and after learning took place in the experimental class and the control class. The data analysis technique in this study was validation analysis using Aiken's V and Interrater Reliability, teacher and student responses, as well as quantitative analysis using the t-test. From the research results it is known that the results of material, language, and design validation, as well as teacher and student responses to the E-worksheet are very feasible and well used in learning so that students are happy and interested in learning. The results of the effectiveness of the E-worksheet effectively influence students' math problems. Judging from the results of the Significance value, which is 0.00, it is smaller than α = 0.05. Based on the gain-score test from using the E-worksheet it gives a moderate gain score of 53%. So that the solving of mathematical problems of students who use PjBL based E-worksheet using Bengkulu special food is higher than students who only use worksheet textbooks from school so that it is declared effective.
