Background: The batik industry produces chemical waste with a COD value of 1918 mg/l; (above the safe threshold of 150 mg/l). One of the wastewater treatment methods is using activated carbon, including corn husks. This study aims to determine the effect of the weight of corn husk activated carbon on the reduction of COD in batik industrial wastewater. Methods: A quasi-experimental study with a non-randomized pretest-posttest control group design using liquid waste from one of the batik industries in Rejomulyo Village, East Semarang District. This experiment applied five weight variations of corn husk activated carbon, namely 10, 20, 30, 40 and 50 grams with 4 repetitions, and 4 control samples. The effect of the treatment was observed in 50 minutes. The observations were analyzed using the Kruskal-Wallis statistical test. Results: The range and mean COD values before and after treatment were 3174.32 -5136.43 mg/l, and 584.29 - 1049.20 mg/l, respectively. The decrease in COD according to treatment ranged from 80.83% to 84.76%, while in the control group it was only 2.90%. There was an effect of the weight of corn husk activated carbon to decrease COD of batik industrial wastewater (p = 0.015), and there was an effect of the weight of corn husk activated carbon to decrease COD of batik industrial wastewater between control group and treatment group (p = 0.021). Conclusion: Corn husk activated carbon has a high potential to reduce the COD of chemical waste in the batik industry.

The purpose of this study was to see the comparison between the administration of Massage Counterpressure and the provision of dark chocolate to reduce menstrual pain (dysmenorrhoea). The design uses a quasi-experimental design with two groups of pretest and posttest with control group design. The results showed that in the dark chocolate and anti-pain medication group, massage counterressure and anti-pain medicine obtained ρ value of 0,000. there are significant differences before and after the administration of action. The results of the man whitney test found that there were differences between the 2 groups with a value of ρ value of 0,000. Conclusion, there is a difference of influence between the dark chocolate group and the counterpressure massage group on the intensity of menstrual pain. Giving 100 grams of dark chocolate for 2 days and anti-pain medication is more effective than a 20-minute counterpressure massage for 2 days and anti-pain medication for menstrual pain intensity.   Keywords: Dark Chocolate, Massage counterprssure, Menstrual pain

The objective of this research exercise is to examine how reciprocal teaching affects 7th-grade students reading motivation in the subject of English. To meet the desired objective, the study employed a quasi-experimental design. The intact classes were randomly allocated to the experimental and control group. The experimental group was instructed with reciprocal teaching strategies, while the control group was taught with the traditional method. The Motivations for Reading Questionnaire (MRQ) was administered before and after the intervention. The study employed Pretest-Posttest Nonequivalent Control Group Design for data collection. The data was analyzed using the independent sample and paired sample t-test. The results of the study revealed that the motivation level of students who were taught with reciprocal teaching is significantly higher than those students who were taught with the traditional method. These results suggest that reciprocal teaching should be incorporated in teacher education programs as appropriate instructional practice for reading.

Breastmilk is the only perfect and best food for babies because it contains the nutritional elements needed by babies for optimal growth and development. Although the rate of exclusive breastfeeding in the Pringsewu Regency has increased from year to year, support for community participation and empowerment in health development has not been optimal. One solution that can help overcome barriers to exclusive breastfeeding is hypnobreastfeeding. The purpose of this study was to determine the effect of hypnobreastfeeding on the motivation of breastfeeding in the Pringsewu Regency in 2019. This research is a quasi-experimental research with pre-post-test design with a control group design. The sampling technique was purposive sampling with a sample size of 48 pregnant women from term to breastfeeding. Data analysis was done by using the Independent Two Mean Difference test (T-Test) using the Paired Sample Test. The results of the study on the Paired Sample Test showed a significant value (p) of 0.004, meaning that there was a significant difference in the motivation of breastfeeding before and after hypnobreastfeeding. Midwives always provide hypnobreastfeeding therapy and lactation education to help increase motivation for breastfeeding as part of efforts to increase exclusive breastfeeding and breastfeeding for up to 2 years or more. For other researchers, it is necessary to carry out further research with other variables that can affect the motivation of breastfeeding.

Stunting occurs in a chronic small intestinal inflammation syndrome, called pediatric environmental enteropathy, resulting in increased intestinal permeability and the entry of immune cells into the intestinal epithelium. The purpose of this study was to study the types of prebiotic food formulas and their effects on LAZ in stunting children. This type of research is a quasi-experimental design with a pretest-posttest control group design. Held in Sei Ambawang District, Kubu Raya Regency 2019. Samples of stunting children aged 12-24 months were 40 children. The sampling technique was used for purposive sampling. The intervention given is prebiotic formula food given for 30 days. Data processing for LAZ, nutrient intake, and t-independent test statistical analysis each using WHO Anthro 2005, Nutri survey, and SPSS software. The results showed there were differences in LAZ before and after in the group given MF-2 food formula in stunting children (p= 0,034), whereas in the group who received MF-1 showed no difference (p= 0,114). Based on LAZ differences between the two groups after the intervention with independent t-test did not show significant differences (p > 0,05). In conclusion, MF-1 and MF-2 did not differ in increasing LAZ in stunting children, but each group showed MF-2 had an effect on increasing LAZ.

The Indonesian government has initiated the provision of iron tablet supplementations to pregnant women. However, the lack of support from the family, especially husbands, in controlling the consumption of these tablets has resulted in the government program not being able to achieve the target set. This quasi experimental study used a pre-posttest model with a control group design. In this study, there were two groups, namely the treatment group and the control group who were given a questionnaire before and after the intervention. The treatment group was given intervention in the form of a husband's mentoring video, while the control group received services in the form of health education with sample size for each group at 47 persons. The results of the analysis showed there were more respondents who experienced the increased knowledge, i.e., 30 persons when compared to those in the control group by only 16 persons. It was then concluded that the use of video to increase the participation of husbands as a companion to remind the wife to consume iron supplementation was significant.
