Modified of Single Deepest Vertical Detection (SDVD) Algorithm for Amniotic Fluid Volume Classification
Get PDFAmniotic fluid a crucial role in ensuring the well-being of the fetus during pregnancy and is contained within the amnion cavity, which is surrounded by a membrane. Several studies have shown that volume of amniotic fluid can vary throughout pregnancy and is closely linked to the health and safety of the fetus. This indicates that it is essential to perform accurate measurement and identification of its volume. Obstetric specialist often use a manual method to identify amniotic fluid by visually determining the longest straight vertical line between the upper and lower boundaries. Therefore, this study aims to develop detection model, known as modified Single Deepest Vertical Detection (SDVD) algorithm to automatically measure the longest vertical line by following medical rules and regulations. SDVD algorithm was designed to measure the depth of amniotic fluid vertically by searching the column of pixels that comprised the image sample, excluding any intersection with the fetal body. Performance testing was carried out using 130 images by comparing the manual measurement results obtained by obstetric specialists and the proposed model. Based on the experimental results using modified SDVD, the average accuracy, precision, and recall achieved for amniotic fluid classification were 92.63%, 85.23%, and 95.6%, respectively

The Influence of a Heuristic Approach with Blended Learning on Students' Critical Thinking Abilities
No full textThe students lack of habit in critical thinking is the background in this research. Lack of abilities due to the use of conventional learning models, so that learning activities are passive. The purpose of this study was to determine whether heuristic learning with blended learning method had an effect on the critical thinking skills of eight grade students of SMPN 12 Yogyakarta. This research is a type of quasi experimental. The population in this study were student of class VIII SMPN 12 Yogyakarta. Where class VIII D is the control class and VIII E class is the experimental class. The object of this research is the use of a heuristic approach with the help of the blended learning method. Data collection was carried out using test techniques. The instrument use in collecting data about students critical thinking skills. The test instrument used is the content validity test. Data processing is done by using descriptive analysis and inferential analysis. Based on the research that has been done, this study shows that the use of a heuristic learning approach with the help of eighth grade students if SMP N 12 Yogyakarta. The result of this study can see from the result of tcount = 2.142 and ttable = 1.99 which means that tcount > ttable so it can be said if there is an effect of using a heuristic approach with the help of the blended learning method on student’s critical thinking skills.
The Effectiveness of Creative Problem Solving Through Concrete Media Towards Creative Thinking Skill of the Fourth Grade Students at SDN 1 Kaliombo
No full textThe process of learning mathematics only focuses on understanding students but have not been able to develop their creative way of thinking. Students do not have the opportunity to explore answers or ways that are different from what the teacher teaches, so students cannot be creative in finding answers. The application of the creative problem solving learning model and concrete media in the form of nets of cubes and blocks is one solution to this problem. The purpose of this research is to find out: the difference in the average value of creative thinking skills after using the creative problem solving model and concrete media for fourth-grade students at SDN 1 Kaliombo. The experimental approach used in this research is the Pre-Experimental Design model in the form of a Pretest-Posttest Group Design. This study used fourth-grade students at SDN 1 Kaliombo as subjects, taking samples using total sampling or census. The research data was obtained from a statistical analysis of the t-test in the form of a Paired Sample t-Test. This study shows that: there is a difference in the average value before and after using the creative problem solving model and concrete media with a significance of 0.000 <0.025. Therefore, the CPS model assisted by concrete media can be said to have an effect on students' creative thinking abilities

Combination of Woolwich massage and hydrogel made from red ginger for breastfeeding mothers to increase baby weight
No full textBackground: The amount of breast milk that nursing moms make is still insufficient, affecting the infant's weight. One attempt to increase the baby's weight is administering a combination of Woolwich massage and red ginger hydrogel, which has never been done in prior studies.Purpose: To demonstrate the impact of a Woolwich massage and red ginger hydrogel on infant weight.Method: This experimental study with a pre-post-test control group design. Thirty-six breastfeeding mother respondents were selected using simple random sampling; 18 were given a combination of Woolwich massage and red ginger hydrogel, and 18 were given standard breast care during the postpartum period. Treatment was given for seven days—analysis of baby weight using the Paired Samples T-Test and the Mann-Whitney test.Results: The average increase in body weight of infants of the intervention group (405,56 g) was higher than the control group (238,89 g), p<0.05.Conclusion: Breastfeeding mothers given a combination of Woolwich massage and hydrogel made from red ginger rhizomes could have babies with a higher birth weight than mothers who were only given standard breast care
Red ginger (Zingiber officinale var. rubrum) nanoparticle extracts on reducing the blood pressure for postpartum hypertension
No full textBackground: Red ginger contains flavonoids, which can cause vasodilation and decreased cardiac output and pressure. Previous research on red ginger on blood pressure has been carried out and showed significant results. However, it has yet to be studied in nanoparticle extracts, where nanoparticles are the best drug carrier system, so it is necessary to research.Purpose: Making and testing red ginger nanoparticle administration (Zingiber officinale var. rubrum) to reduce blood pressure in hypertensive postpartum mothers.Methods: This is an experimental study with a pre-post control group design. The sample consisted of 40 postpartum hypertensive mothers divided into two groups, namely 20 interventions and 20 controls. The intervention group was given red ginger nanoparticles made using the bottom-up method with a dose of 300 mg and the antihypertensive drug nifedipine, while the control group was given the antihypertensive drug nifedipine alone; both were given for two weeks. Data analysis used the Independent t-test and reapeted ANOVA tests.Results: The systolic blood pressure in the intervention group decreased by 12.95 mmHg on the 7th and 28.4 mmHg on the 14th day (p<0.001) while the control group was 7.05 mmHg on the 7th day and 14.8 mmHg on the 14th day (p<0.001). Diastolic blood pressure in the intervention group decreased by 3.55 mmHg on the 7th day and 11.90 mmHg on the 14th day (p<0.001), while the control group was 2.88 mmHg on the seventh day (p<0.007) and fifth day 35 mmHg on day 14 (p<0.002).Conclusion: Giving red ginger nanoparticles can reduce blood pressure in postpartum hypertensio
