Background:Dysmenorrhea is a gynecological problem defined as cramping pain in the lower abdomen that occurs during menstruation. Management of dysmenorrhea can use non-pharmacological therapy such as warm compresses. Warm compresses can cause blood vessel dilation (vasodilation) so that it can increase blood circulation, relieve ischemia in myometrial cells, decrease myometrial smooth muscle contraction, increase muscle relaxation and reduce pain due to spasm or stiffness. Methods: This research is a quantitative research. This research method is pre-experimental with one group pretest-posttest design. The sampling technique is purposive sampling. The sample in this study were 74 students who experienced dysmenorrhea in January 2022. Data was collected using the Numeric Rating Scale (NRS) dysmenorrhea pain scale observation sheet before (pretest) and after (posttest) warm compresses were given. Data were analyzed using the Wilcoxon Signed Rank Test. Results: After the Wilcoxon Signed Rank Test, the results showed a p-value of 0.000. The p value is smaller than the significant value or Sig. (2-tailed), which is 0.05(p < 0.05) so that H0 is rejected, and Ha is accepted. Conclusion:Based on the results of this study, it can be concluded that there is an effect of giving warm compresses to the decrease in the degree of dysmenorrhea in students of MAS Ushuluddin Singkawang City in 2022.

Background :In Indonesia experienced a very worrying Extraordinary Event (KLB), namely the incidence of Diphtheria. Diphtheria incidence in Indonesia has always fluctuated since the 1980s. In 2007 there were 183 cases of diphtheria which increased to 1,192 cases in 2012 and decreased incidence of diphtheria in 2013-2016 (Sariadji, 2017). And according to the Indonesian Pediatrician Association (IDAI), the diphtheria outbreak in Indonesia is the highest in the world. Diphtheria outbreaks occurred in 28 provinces and 142 districts / cities. So there has never been the most in the world and the coverage is 28 Provinces, "said the Chairman of the Indonesian Pediatrician Association, Aman Bhakti Pulungan, during a press conference at the IDI office Jalan Sam Ratulangi, Central Jakarta (Nugraha, 2017). As of November 2017, there were 20. provinces that have reported diphtheria with 593 cases and 32 deaths. Director General of Disease Prevention and Control Ministry of Health, Mohamad Subuh said, 66 percent of the total prevalence did not immunize. Then, 31 percent did immunization, but not until the final stage. To be free from diphtheria, at least the individual must get three times the immunization. Meanwhile, the remaining 3 percent has received complete immunization (Putra, 2017). The purpose of this study is the relationship between work status and completeness of basic immunization in infants. Method : quantitative with cross sectional approach. Research location Pus public health Botania. The population in this study were all live births in the Botania Community Health Center working area, namely 2184 people. This sampling technique uses purposive sampling method, data analysis uses bivariate data analysis with statistical tests, namely the Chi Square test using the SPSS program. Result : shows that out of 96 respondents the majority have a working status of work as many as 54 people (56.2%), majority were incomplete as many as 56 people (58.3%). Chi-square analysis results obtained p-value 0.000, which means p-value <0.05 so that Ho is rejected

Background : Abortion is the threat or release of the product of conception at ≤ 20 weeks of gestation. In the world there are 20 million cases of abortion every year and 70,000 women die from abortion each year. One of the causes of abortion, among others, parity, maternal age, infectious diseases. This study aims to determine the relationship between parity and abortion. Method : The research method used was an analytic survey with a cross sectional approach. Conducted at ST Elisabeth Hospital, Batam City, the study was conducted for 6 months, all pregnant women recorded in the medical records at Santa Elisabeth Hospital, Batam City, namely 242 pregnant women for the period 2020. Sampling was using total sampling technique with research instruments using checklists. Data analysis using Chi square. Result : The results showed that most pregnant women with primiparous parity were 126 people (52.1%). Of the 242 pregnant women, 124 (51.2%) did not abort and 118 (48.8%) experienced abortion. Based on the results of the chi-square statistical test analysis, the value of ρ value was 0.002 smaller than α (0.05). Conclusion : Which means that there is a significant relationship between parity and the incidence of abortion at Santa Elisabeth Hospital. Suggestions to further researchers to be able to expand the research by taking more samples from several other hospitals, in order to strengthen the accuracy of the research results.

One of the causes of bleeding during pregnancy is placenta previa, which is the placenta that covers all or part of the internal uterine ostium. One of the risk factors for placenta previa is Age because it can cause sclerosis of small arteries and myometrial arterioles which causes uneven blood flow to the endometrium so that the placenta grows wider with a larger surface area. So the researchers wanted to look for a relationship between maternal age and placenta previa. This research method is analytic observational with a cross-sectional approach conducted at the Camatha Sahidya Hospital in Batam City in 2019. Data is taken from the patient's medical record from June 1 to June 31, 2019. The sampling technique is total sampling where the number of samples is the same with a population of 135 people in June 2019. The results of the study were analyzed by frequency distribution in a cross-tabulation then tested by Chi-square test. The results of this study showed that out of 135 mothers, 4 mothers (17.4%) out of 23 mothers aged> 35 years were declared into the Placenta Previa group and 19 mothers (82.6%) out of 23 mothers aged> 35 years were stated in the group. No Placenta Previa. And obtained 112 mothers aged 20-35 years from 135 mothers in which there were 2 mothers (1.8%) who were stated in the Placenta Previa group and 110 mothers (98.2%) stated in the No Placenta Previa group. Chi-Square analysis results obtained significance value p = 0.008. This figure is significant because the p-value is smaller than the significance level () = 5% (0.05). Therefore it can be concluded that there is a significant relationship between maternal age and the incidence of placenta previa. Based on this study it can be concluded that there is a significant relationship between maternal age and the incidence of placenta previa.
