Abstract

Counseling on Clean and Healthy Living Behavior (PHBS) is an activity to convey health messages to the community, groups or individuals in the hope of gaining knowledge about better health, which in the end this knowledge can change the behavior of the community itself. Diarrhea is a disease that occurs due to bad habits of the community, and the most severe risk factor for this disease is death. This study aims to determine the effect of PHBS counseling on changes in people's behavior to prevent diarrhea. This research is a pre-experimental study with one group pretest-posttest design. The pretest is the observation of public health behavior to prevent diarrhea before PHBS counseling, the treatment is in the form of PHBS counseling to the community, while the posttest is the observation of public health behavior to prevent diarrhea after PHBS counseling. Participants as extension subjects came from Waworada, Sie Village, Bima City - Indonesia. The number of participants was 64 people with various characteristics ranging from gender, age, and education. Health behavior was measured using a questionnaire that was conducted to the participants. Each behavioral data was analyzed descriptively and statistically (using paired t-test). The results of the study have shown that the initial observation, before PHBS counseling, most of the people behaved "enough" in preventing diarrheal diseases. After the implementation of PHBS counseling, most of the people behaved "good". That is, descriptively people's behavior changes in preventing diarrheal diseases with PHBS counseling. Statistically, this behavior change was tested and it was found that there was an effect of PHBS counseling on people's behavior to prevent diarrhea (p 0.000 < 0.05). It is hoped that the results of this study can provide empirical evidence, so that the inculcation of health knowledge through counseling can continue to be carried out in a structured manner to the wider community.

Abstract

Free radicals are unstable molecules caused by several electrons in the molecule that does not have a partner. Free radicals can potentially trigger the onset of various degenerative diseases. One of the efforts that can be made to ward off the disease is by consuming antioxidant compounds. Antioxidant compounds can be found in plants with the genus Allium, such as Allium cepa L. This study aims to determine antioxidant activity, flavonoid concentration, and phenolic concentration in Allium cepa L extract. The DPPH method (2-2-diphenyl-1-picryhydrazil) is used to determine antioxidant activity, calorimetrically determined flavonoid consensuality with AlCl3, and the Follin-ciocalteu method is used to determine the phenolic consensual consensuality in the sample. The multilevel maceration method in sample extraction uses different polarity solvents, dichloromethane, ethyl acetate, and 96% ethanol. Based on the research data, flavonoid and phenolic compounds were found in 96% ethanol extract but in dichloromethane and ethyl acetate extracts were not found. The concentration of flavonoid ethanol extract is 96% by 4,125 mgQE/gr extract. Phenolic concentration in ethanol extract was 96% by 1,071 mgGAE/gr extract. The IC50 value in ethanol extract is 96% which is 201,221 ppm. These results show that the antioxidant activity of Allium cepa L is classified as moderate, with IC50 values being between the range of 100-250 ppm.

Abstract

This study aims to identify students’ mathematical critical thinking ability in solving HOTS problems based on cognitive styles and gender. It is a descriptive and qualitative study. It used the purposive sampling technique to determine 4 subjects based on the categories of impulsive and reflective cognitive styles covering both male and female students. Data were collected by interviews, documentation, the MFFT test, and the mathematical critical thinking skill test using HOTS questions. The results showed that students who have the impulsive cognitive style could meet the FRISCO indicators in solving HOTS questions. Students with a reflective cognitive style could not meet the indicator of reason as they were unable to provide supporting reasons related to the information found. Female students provided a more detailed, coherent, and clearer explanation in solving HOTS questions compared to male students.
