Abstract

This study aims to create mathematics learning devices such as a syllabus, lesson plans, and student worksheets for the 9th grade of junior high school using discovery learning on curved face three-dimensional (cylinder, cone, and sphere) material. The incompatibility instruments arranged by the teacher based on the 2013 Curriculum inspired this research. The 4-D development model was used in this study, and it consists of defining, designing, developing, and disseminating stages. The validation sheet and student response questionnaires were the instruments used in this study. The learning that was developed was validated by three of the validators and revised based on their suggestions. With very valid categories, the average score of the validation results for the syllabus is 3,79, lesson plans are 3,81, and student worksheet is 3,73. This validation indicates that the syllabus, lesson plans, and student worksheet can be sampled. Then, in small groups, valid student worksheets are tested. The average percentage of small group trial results for student worksheets is 92,29 percent, with a very practical category. Based on the results of data analysis and discussion, it can be concluded that syllabus, lesson plans, and student worksheets by using discovery learning on curved face three dimensional material for the 9th grade of junior high school has fulfilled valid

Abstract

The rising number of obesity cases among children and adolescents has become a significant public health concern. One contributing factor is the lack of understanding about balanced eating patterns. This community engagement activity aimed to increase public knowledge about the importance of the Isi Piringku (My Plate) concept in preventing obesity, using animated video-based educational media. The educational video was disseminated online through social media platforms Instagram and Facebook. Respondents who accessed the video were asked to complete a post-test and provide feedback via Google Forms. Results showed that out of 117 respondents, the majority stated that the video was easy to understand and improved their knowledge of healthy eating patterns. The highest user interaction was recorded on Instagram, with 190 likes, 69 comments, 11 shares, and 1,500 views. This activity demonstrates that social media can serve as an effective tool for nutrition education, capable of reaching a wide audience efficiently.

Abstract

This study aims to improve the reading literacy skills of fifth-grade students at SDN 238 Palembang in the Indonesian language subject through the implementation of the Student Teams Achievement Division (STAD) learning strategy assisted by interactive quizzes. The main problem faced is the low level of students’ reading literacy skills, as indicated only 7.41% of students achieving the Minimum Completeness Criteria (KKM) before the intervention. This research is a Classroom Action Research (PTK) conducted in two cycles, which included the stages of planning, implementation, observation, and reflection. The results showed a significant improvement in students’ reading literacy skills. In the first cycle, learning mastery reached 48.1% with an average score of 63.5, and in the second cycle, it increased to 81.4% with an average score of 81.1. The implementation of interactive quizzes such as Wordwall and Baamboozle in the STAD strategy also proved effective in enhancing active participation, collaboration, and students’ learning motivation. Therefore, the STAD learning strategy assisted by interactive quizzes can be considered an effective alternative teaching strategy to improve reading literacy skills at the elementary school level.

Abstract

Housing development is one of the important sectors in infrastructure development in a country. However, housing projects often faces challenges in terms of scheduling and time management. Therefore, project scheduling analysis is crucial to ensuret each stage of the project is completed on time and  within  predetermined budget. This study aims determine the processing time of the Tallasa City Alstonia cluster housing construction project using the Project Evaluation Review Technique (PERT) method of development, and to identify the critical activities in housing construction projects. The data collection method used includes direct field observation and the use of the available project time schedule to obtain information on the duration and sequence of each task. The collected data is then analyzed using the PERT method to estimate three times: optimal time, pessimistic time, and most likely/ realistic time. The results showed that the construction duration of the Alstonia Cluster housing project is 351 days, while the planned Time Schedule is 240 days. The conclusion of the PERT analysis indicates that the project is 111 days later than the planned time.
