Measurement of uterine fundal height (TFU) to determine the estimated fetal weight (TBJ) is an important component of antenatal care in labor management. Babies born with low body weight or born with very large body weight are associated with increased complications during labor and the puerperium. This study aims to compare the accuracy of the Risanto and Johnson Toshack formulas in determining the estimated fetal weight. The design of this study was cross-sectional, with the sample being parturient mothers in the PMB working area of the Tangkit Health Center in 2022 who met the inclusion criteria, which amounted to 87 people. The sampling technique is accidental sampling. The results showed that the Risanto and Johnson Toshack formulas were compatible in estimating the baby's birth weight (p-value 0.497 and 0.377). The average difference between the TBJ of Risanto's theory and the baby's weight is 34.42 grams, while the average difference between the TBJ of Johnson Toshack's formula is 171.15 grams. The test results comparing the accuracy of the Risanto formula and the Johnson Toshack formula, the average value of TBJ Johnson Toshack is greater than the average value of TBJ Risanto, and TBJ Risanto is closer to the baby's birth weight. The conclusion of this study shows that Risanto's TBJ measurement is more accurate than Johnson's TBJ Toshack. Measurement TBJ uses the Risanto formula that health workers can apply to detect fetal well-being, including estimated fetal weight during pregnancy and delivery.

This study aims to determine the effect of health education on personal hygiene with audio-visual media (video) on the knowledge and behavior of adolescent girls. This quantitative research method uses a pretest-posttest design with a control group design with the type of intervention using video learning in the intervention group. The results of the t-test showed that the knowledge aspect was p-value = 0.587 (p > 0.05), while the behavior was 0.011 (sig < 0.05). In conclusion, health education using audio-visual (video) is proven to improve the behavior of adolescent girls in improving personal hygiene and is more effective than learning using PPT.   Keywords: Menstruation, Knowledge, Behavior, Personal Hygiene

Various studies have shown that adolescents have very complex problems along with the transitional period experienced by adolescence, a problem that stands out among adolescents, namely the problems surrounding TRIAD KRR (sexuality, HIV and AIDS as well as drugs). The role of the media is important in shaping the knowledge of adolescents in understanding reproductive health problems. Multimedia is a combination of media which is more than two media consisting of integrated text, graphics, images, photos, audio, video and animation. This study uses research and development (R and D) methods. The population in this study were students at SMPN 19 Jambi City. The sample was selected using purposive sampling technique totaling 35 students. This research was conducted from March to November 2020. The data analysis in this study used qualitative analysis techniques and quantitative descriptive. Quantitative data collection was carried out by measuring the level of students' initial knowledge (pre-test), then introducing a 10-minute video media for adolescent reproductive healt. Evaluation is carried out by measuring the level of knowledge (post test) and evaluating student responses to the experience of accessing the developed video.  Overall the percentage level of media feasibility by material experts is 98.6% with the very feasible category. The results of eligibility by media experts obtained a percentage level of 80% with the feasible category.The results of the Wilcoxon test showed a significant difference (r-value 0,000) from the students' knowledge before and after the intervention was given. The results of the percentage of respondents' responses to the media are 93% with a very good. For further research, it is hoped that this video media can be developed with a more specific topic regarding adolescent reproductive health while still paying attention to the duration of the video and can also be developed learning media with interactive multimedia.
