This study aims to analyze the achievement of each indicator that measures students' mathematical understanding abilities in basic physics courses on particle dynamics material. This research is a qualitative descriptive study that seeks to describe the analysis of students' mathematical understanding abilities. The research subjects were 6 class 3 semester students of biology education consisting of 198 students. The data collection method used includes tests of students' mathematical understanding abilities in basic physics courses which include particle dynamics material. Based on the results of the study, it was concluded that the level of ability of biology education students in basic physics courses was as follows: (1) Students already had the ability to solve problems was good enough on particle dynamics material from questions 1 to 5 had an average percentage of 56.2% , (2) Students have reasoning abilities (reasoning on particle dynamics material from questions 1 to 5 have an average percentage of 14.4%, (3) Students have communication skills (communication) on particle dynamics material from questions 1 to 5 have The average percentage is 12.2%, (4) students have the ability to make connections to the dynamic material of particles from questions 1 to 5, have an average percentage of 12.4%; (5) students have representation ability ) on the particle dynamics material from questions 1 to 5 has an average percentage of 4.8%.

Shifts in lifestyle and food consumption patterns of the community have an influence on the nutritional status of the community. Along with the development of science and technology, people are faced with an unhealthy lifestyle, people tend to prefer and like the types of practical and fast food, soft drinks that are widely circulated in the market or contemporary drinks that are trending in society, lack of exercise, unbalanced diet, and much more. Based on the results of observations made, it shows that in the Jl. Budi Mulia RT 04 RW 07, Pademangan, North Jakarta that teenagers in this area consume high levels of fast food. One way for optimal health is to regulate the food consumed by paying attention to good nutritional intake. then our community service team will provide training on making "Nugget Processed Creations from Banana Hearts as an Alternative for Healthy Snacks" and obtained data that: 1. As many as 17 people or 85% answered that they had never made nuggets from banana hearts before, 2. as many as 19 people or 95% answered that they would make nuggets from banana hearts after receiving training, 3. as many as 15 people or 75% answered that they would make nuggets from banana hearts after receiving training as a business opportunity.

This study aims to develop learning instruments using 3D hologram videos in the Hybrid period. This research is research development (Research and Development). Research and development research methods are research methods used to produce a certain product, and test the effectiveness of certain products. Development research is a process or steps to develop a new product or improve existing products, which can be accounted for. To test the effectiveness of existing products so that they can function in the wider community, research is needed to test the effectiveness of these products. The product produced in this study is a learning media based on 3D hologram videos. This 3D hologram-based learning media research will be carried out at SMP Negeri 223 East Jakarta with the research subjects being Grade VIII students and the research object being 3D hologram video learning media in Mathematics. The results of the research are in the form of 3D hologram videos combined with inverted pyramids and smartphones as learning media using the Hannafin and Peck development model which consists of stages: needs assessment, design phase and development and implementation phase. phase). This media has gone through a validation process by media experts with assessment aspects in terms of appearance, language, and effectiveness and reliability.
