The obesity rate among adolescents in Indonesia is increasingly worrying. Obesity in adolescents is affected by a variety of factors, including lifestyle changes that tend to lead to an unhealthy diet and lack of physical activity. To overcome this problem, early prevention efforts are very important, one of which is by measuring Body Mass Index (BMI) as an early indicator of obesity. This research uses a Research and Development (RnD) approach, which aims to develop or improve existing tools to obtain new data and insights into the use of these tools in various contexts. This tool is a development of the previous tool with the HC SR04 sensor to measure height, the Load Cell sensor to measure weight, and the Atmega328p microcontroller to calculate BMI. The main innovation of the tool is the use of a 433 MHz Radio Frequency module that allows wireless communication between height and weight data, increasing the mobility of the tool as it does not require cables and poles as a support. With the result of an error value in the IMT measurement of 1,28%. With an error value of 1.28% in BMI measurements and 93.40% in BMI measurement validity. So from the results of the above percentage, it can be stated that this tool is suitable for use.

Background:  Tooth  decay  can  affect  the  health  of  other  parts  of the  body,  thereby hampering daily activities. One of the factors that can damage teeth is the habit of consuming food and drinks, some of which are healthy, some of which damage teeth, causing dental caries. The current phenomenon is that children entering school age are generally at high risk of experiencing dental caries, because at that age they are used to consuming various types of food and drinks that cause dental caries (such as candy, chocolate, pastries, etc.). Purpose: this research is to determine the correlation between cariogenic food consumption habits and dental caries in grade V elementary school children at SDN 1 Bukit Tunggal Palangka Raya. Methods: The sampling technique used total sampling to obtain 62 respondents, data collection used a questionnaire on habits of consuming cariogenic foods and a dental caries examination observation sheet which had gone through validity and reliability tests, for data analysis using the chi-square statistical test. Results: Based on the analysis, the results of statistical tests using the chi-square method show a sig (2-tailed) number with a p- value of 0.00 with a degree of significance of p < 0.05, so the decision is that H1 is accepted, meaning there is a Habit Correlation Consumption of Cariogenic Foods with Dental Caries. Conclusion: There is a correlation between cariogenic food consumption habits and dental caries. It is recommended that parents pay more attention to maintaining their children's dental health and know the types of food or snacks that can cause caries. Furthermore, it is recommended that schools carry out promotive and preventive efforts regarding dental and oral health carried out by teachers, especially UKS and UKGS supervisors.  

The aim of this research is to develop valid and practical learning media for the basics of visual communication design. The process of learning the basics of visual communication design at SMKN 1 Pasaman is not optimal, this is caused by several problems, namely the availability of learning media only in the form of printed books that students borrow from the school library. This causes students to not understand the learning material and be less motivated to study and cause low student grades. Based on the data obtained, the students' KKM completion score was only 53%. This research uses the Research and Development (R&D) research and development method with the ADDIE model which consists of 5 stages, namely Analysis, Design, Development, Implementation and Evaluation at each stage. This research involved 36 class X DKV students who took part in learning the basics of visual communication design. The results of this research are Android-based learning software that can be used as a complement to the learning process, especially in the basics of visual communication design subjects. Data collection techniques are in the form of observations and questionnaires, while data collection instruments are in the form of validity questionnaires and practicality questionnaires. The data analysis technique uses a Likert scale with the Aiken formula. The results of this research show that the validity value of the media is an average of 81.53% in the "Very Valid" category, while the validity of the material is an average of 93.85% in the "Very Practical" category and the teacher's practicality assessment is an average of 81.77% in the "Practical" category. " while students' practicality assessment averaged 83.3% in the "Practical" category.

Based on the Man 2 Tapanuli Tengah researchers' observations, it was shown that teaching at Aqidah Akhlak was constrained by students' low motivation to learn. The purpose of this study is to elucidate the causes of students' low motivation to learn Akida Aflaq. The reasons for the low learning motivation of Akida-Aklak students are that teachers still use traditional models, students get bored quickly because teachers do not use media effectively in learning, and students do not participate actively in learning because they do not have the courage to discuss or express their opinions during learning. Various learning models and methods, such as the Student Times Achievement Division learning model, can be applied to these problems to motivate students to learn. This study is an experimental study aimed at checking some things and confirming their results in order to test something. Data collection techniques can also be measured using questionnaires, validity tests, reliability tests, etc. Therefore, the obtained research results show that the learning model is not correctly applied by the teachers when learning, so that the students with Akida-Aklak have low learning motivation, get bored easily, and lack the courage to discuss and express their opinions during learning. To overcome this problem, it is very important to pay attention to the models and media used for learning so that teachers can adequately achieve the learning objectives.
