Abstract

According to the results of interviews conducted at junior high schools in the Lebak area, learning activities aimed at developing students' critical thinking skills have not been carried out properly. For this reason, teaching resources that can be used are digital leaflet teaching materials. This study animed to obtain the feasibility and legibility of digital leaflets with the topic "my food, my health" which is oriented toward the critical thinking skills of grade VIII junior high school students. The research methodology used was Research and Development, limited according to the abilities and needs of researchers, namely using three stages: define, design, and develop stages. A questionnaire instrument sheet is a tool used for investigation, which will be assessed by material validators, media, and practitioners, as well as readability by students with quantitative descriptive and qualitative descriptive data analysis. The findings of this study indicate that digital leaflets with the topic "My food, my health" can be used to help grade VIII students of junior high school develop critical thinking skills that based on media validation, scored 87.5% in the "very appropriate" category, while material validation scored 93.45% in the "very feasible" category, while practitioner validation obtained a score of 89.22% in the "very appropriate" category and readability students get a score of 91.88% with very good category.

Abstract

Era 4.0 is often referred to as the technological era. One application of technology in the industrial sector is the creation of a 4-arm robot. But in his case, 4-arm robots are rarely operated automatically. Therefore, a 4-arm robot simulation was designed using servo motors via Bluetooth. This research aims to design a 4-arm robot that is controlled using Bluetooth. The methodology used is the simulation method and literature study. The results of the simulation of a 4-arm robot controlled by Bluetooth can rotate at an angle of 45° and 90° and move automatically
