In this study, we analysed the sea pollution caused by sewage from vessels. The Dubrovnik aquatorium was chosen as a typical sea area that accommodates a variety of vessels in different locations. We sampled the sea at eight different coastal locations over 14 months and then analysed the samples to determine the presence of the indicators of fecal pollution. Simultaneous with the sampling of the sea, we recorded the number and type of vessels accommodated at the port. These data were applied in chi-square tests, which were used to determine the existence of the relationship of certain types of vessels with fecal coliform bacteria in the sea for each location. The correlation was determined between smaller vessels such as boats, yachts, megayachts, and smaller cruise ships in national navigation with bacteria at sea at the sampling locations. The results can provide an improved understanding of sea pollution due to sewage from vessels.

Fecal Coliform Bacteria

Water is the main source for life and also the most severe substance caused by pollution. The mandatory parameters for determining microbiological quality of drinking water are total non-fecal Coliform bacteria and Coliform fecal (Escherichia coli). Coliform bacteria are a group of microorganisms commonly used as indicators, where these bacteria can be a signal to determine whether a water source has been contaminated by bacteria or not, while fecal Coliform bacteria are indicator bacteria polluting pathogenic bacteria originating from human feces and warm-blooded animals (mammals) . The water inspection method in this study uses the MPN (Most Probable Number) method which consists of 3 tests, namely, the presumption test, the affirmation test, and the reinforcement test. The results showed that of 15 drinking water samples 8 samples were tested positive for Coliform bacteria with the highest total bacterial value of sample number 1, 15 (210/100 ml), while 7 other samples were negative. From 8 positive Coliform samples only 1 sample was stated to be negative fecal Coliform bacteria and 7 other samples were positive for Coliform fecal bacteria with the highest total bacterial value of sample number 1 (210/100 ml).

The well is one of the source water used for bathing, washing, and drinking by the citizens in Jiken Hamlet, Rarang Village, Terara Sub-District. Poor dug well construction conditions can affect the amount of coliform bacteria contained in the dug well water. The purpose of this study is to identify the construction of dug wells and the content of coliform bacteria in dug well water and determine the relationship between dug well construction and the content of coliform bacteria. This research is analytic with a cross sectional study design. The results were obtained from 11 samples of dug wells which were observed in construction and the coliform content was known that all samples did not requirements as good dug well construction. Coliform content test results showed that as many as 5 dug well water samples did not pass the clean water quality standards. The results of data analysis with the chi-square test variable construction of dug wells with coliform content variable  showed 0,172 > 0,05, then the concluded is the dug well not suitable to use by people in that area as a source of water for daily needs.

This research is analytic with an approachof a sectional cross. The study population was all post partum mothers in the Dr. M. Soewandhie Surabayahospital in January 2016 to March 2017, which amounts to an average of 1840respondents while theresearch sample number 182. Measuring collection sheet data obtained by systematic random sampling.The Study was conducted Chi-Square test obtained mean count X2 (0,00) is less than á (0.05) thenH0 is rejected and H1 accepted it means that there is a relationship between the age of high risk withbleeding post partum. Conclusion, there is a relationship between the age of high risk with the incidenceof bleeding post partum in the Spaceof the Maternity room Dr. Moch. Soewandhie Surabayahospital.

In the current era of globalization, humans always interact with technological developments. One result of the development of technology is the use of computers. The use of computers that are not under the ergonomic position causes effects on health, one of them is tension-type headaches. In the United States, 1-4% of patients coming to the Emergency Care Unit complain of headache, 90% of them are tension-type headaches. The proportion of migraine and other headache syndromes in the hospital. Harapan Bunda in 2011 and RS. Camatha Sahidya in Batam in Batam was 5% and 0.7% respectively. Whereas the incidence of tension headaches in 5 puskesmas in Batam in 2014 ranged from 0.5% - 1.3%. The proportion of tension headaches at the BIP Clinic in the January-April 2018 period is 1.5%. Tension-type headaches that occur continuously can cause barriers to daily activities. The purpose of this study is to determine the relationship of computer use with the incidence of tension-type headaches in workers. This research uses a descriptive-analytic method with a cross-sectional approach. The sampling technique is purposive sampling. Of 97 respondents who visited the clinical BIP that met the criteria, it was found that computer user respondents experienced tension-type headaches of 18 people (42.9%) and not tension-type headaches of 24 people (57.1%). Whereas the respondents who were not computer users experienced tension-type headaches of 10 people (18.2%), and non-tension-type headaches of 45 people (81.8%). Bivariate chi-square analysis showed that p = 0.008 (p <0.05). This means that Ha is accepted and H0 is rejected.

Postpartum hemorrhage is bleeding that occurs after the birth of the baby, placenta, and 2 hours after the placenta is born. One of the causes is anemia. Research in 2015, 60% of 100 mothers giving birth at RSIA Kirana Taman Sidoarjo experienced postpartum hemorrhage. The aim of the study was to determine the relationship of anemia in pregnancy with the incidence of postpartum hemorrhage in labor mothers. The study design used an analytical survey with a retrospective method. The population of 206 maternity mothers was taken with simple random sampling technique as many as 136 samples in August 2017. Data were analyzed by Chi Square statistical test with 0.05. The results showed that postpartum hemorrhage was more experienced by mothers with anemia (66.7%) than  those without anemia (26.2%). While those who did not experience postpartum hemorrhage were more experienced by mothers who were not anemic (73.8%) than those who were anemic (33.3%). Chi square test results  (p=0.000  <0.05),  which means there is a relationship  of anemia in pregnancy with the incidence of postpartum hemorrhage in labor mothers. Conclusions of the study were the relationship of anemia in pregnancy with the  incidence  of postpartum hemorrhage in labor mothers. It is expected that midwives and doctors conduct early detection of anemia so that appropriate care can be carried out.
