The purpose of this study was to obtain valid and reliable data or facts related to the effectiveness of instructional video media in improving nutritional knowledge and reproductive health in young women. The problem in this study is the lack of knowledge of young women about nutrition and reproductive health and the lack of use of learning media in schools. This research is quasi-experimental research in the form of a pretestposttest with a control group design with 180 respondents in several vocational schools in Jakarta and Bogor. The normality test is done using the formula Lilliefors and obtained Larithmetic for learning video media by 0.110 and Larithmetic for conventional media 0.126 with Ltable = 0.093, because Larithmetic > Ltable, it can be concluded that the two data is not normally distributed. The influence between the two groups can be seen using the Mann Whitney test to obtain a Zarithmetic of 1.539 and Ztable value at α = 0.05 of 1.200. Based on the calculation results, it can be concluded reject Ho if Zarithmetic > Ztable, which means H1 is accepted, and there is an increase in the knowledge of the experimental group given higher learning video media treatment compared to the control group given treatment using PowerPoint media. So it was concluded that there was an increase in knowledge on the use of video media for learning nutrition and reproductive health in young women.

The Impact

The research is aimed to produce an effective social-personal guidance to develop students' moral behavior. This research uses quantitative approach with quasi experimental method and non-equivalent control group design to students class VIII of SMP Negeri 26 Bandung. Data analysis techniques used to find out the effectiveness of personal-social guidance in developing the moral behavior of students in SMP Negeri 26 Bandung Academic Year 2017/2018, include: 1) normality test; 2) homogeneity test; and 3) independent t test. The results show that in general social-personal guidance is not effective in developing students' moral behavior. But in particular there are five significant indicators, which is; 1) impose obligations as a child; 2) help others sincerely; 3) share / share information; 4) show concern for others; 5) guiding others to the task, and two insignificant indicators, namely; 1) understanding school rules; 2) consider the impact of lying.

The closure of schools due to the Covid-19 pandemic has forced all schools in Indonesia to be closed temporarily, therefore learning must be carried out online. Online learning is commonly carried out with teacher presentations and assignments therefore this makes learning monotonous and boring for students. So we need a medium that makes learning more interesting, namely with interactive powerpoints. The purpose of this study was to determine the effect of using interactive powerpoints in the online-based TGT model on thermochemistry material. This type of research is quasi-experimental research with a post-test only control group design. The data collection technique used the technique of daily test tests, documentation, and student perception questionnaires. The data were analyzed using the normality test, F test, and t test with a significance level of 5%. The results showed that before being given the treatment, the two classes were normally distributed, homogeneous variations and there was no difference in student absorption. After being given the treatment, the two classes had significant differences in absorption. Therefore it can be concluded that there is an effect of using interactive powerpoints in the online-based TGT model on thermochemistry material.

Nutrition education for children is important to instill healthy eating habits from an early age. The aim of the study was to analyze the effect of nutrition education on nutritional knowledge and intake of vitamin C and iron for students of SMPN 1 Bayang. This type of research is a quasi experimental design with a pre-post control group design approach. The research was conducted in February - September 2020 at SMPN 2 Bayang. Nutritional education using a zoom application and accompanied by social media (whatsapp group) carried out every 2 weeks for 6 weeks as much as 3 times nutrition education. Data collection was carried out by phone and google form. Data analysis using paired sample t-test analyzed the mean differences in the level of knowledge, and intake of micronutrients (vitamin c and iron). Results Based on the social media-based nutrition education, it was found that nutritional knowledge and vitamin C intake increased significantly (P <0.05). Conclusion Social media-based nutrition education can increase student knowledge and student vitamin C intake. Recommendation It is better if nutrition education is done intensively so that it can change students' behavior. Keywords : online nutrition education; nutritional knowledge; adolescents; Vitamin C intake; Iron intake
