The problem at informal sector in particular for farmer when used the pesticides. In Sumber Mufakat village the farmers always use the pesticides without using the safety equipment and have direct contact with the pesticides exposure. The purpose of this research was to apply the safety talk and check method as prevention method to solve the pesticides toxicity that asses from safety and health of pesticide use behaviour. This preventive intervention research was using Participatory Action Research (PAR) design.The data collected by observation, quetionaire, and health check list. The population was all holticultura farmers in Sumber Mufakat village that divide in nine farmer's group. The sample collected by using proportional random sampling. The data will analyze by using qualitative descriptive. The result showed that the implication of safety talk and check method could prevent of pesticide exposure that present from safety and health of pesticides use behaviour. To support the action of safety talk method needed to develop one community that care about the farmers with government endorsement. The check method was very helpful the farmers to identify and predict their health. Both of it could be to cultivate the farmer in safety of pesticide used and early discovery of health symptom cause pesticide used.

Stunting is one of major problem in the world, including Indonesia. Its prevalence 30.8% in 2018. It is a chronic growth faltering caused by low food intake and long-term disease makes child shorter than the average of the same age. The objective of the research was to assess the relationship of caries experience and food intake with stunting in 6-8 years-old elementary school children in Pantai Labu in 2018.The research used a cross-sectional approach. The samples were 144 aged 6-8 years-old, taken by using a cluster sampling technique. Stunting was assessed by measure the value of height to age, caries experience was measured by using the def-t index and food intake were calculated by using food recall 24 hours. The data were analyzed by using the Chi-square test and multiple logistic regression tests. The result of this study indicated that stunting children occurred due to high caries experience (52.4%) and low protein intake (54%). The result of Chi-square test showed that there was the relationship of caries experience (p=0.004; PR=2.150, CI=1.216-3.799), and protein intake (p=0.001; PR=2.376, CI=1.338-4.219) with stunting. The result of multiple logistic regression tests indicated that low protein intake the most dominant correlate with stunting (p=0.001; PR=3,950, CI=1.725-9.405). The conclusion was high caries experience and low protein intake was risk factor for stunting. Stunting in children is 3 times comes from low protein intake and have a chance about 89% causing stunting compared to good protein intake.

Marantha arundinacea L. or arrowroot is a tropical plant that can be taken tuber as processed food product. This plant bulbs can be made flour to produce food, such as fresh bread done in this study. The research was conducted in 2017 at the Nutrition Lab of the Faculty of Public Health of the University of North Sumatra for making of fresh bread and Balai Penelitian Standardisasi Industri (Baristan) Medan for the examination of nutritional quality, from the production of bread from flour bulbs Marantha arundinacea L. and wheat flour. Nutritional analysis performed include moisture content, ash content, fat content, carbohydrate levels, protein content. The results found that the quality of nutrition examined varied. The addition of more arrowroot flour in the production of fresh bread will increase the levels of crude fiber, and carbohydrates. It is expected that arrowroot flour can be used as a mixture in the manufacture of food such as fresh bread added to the ingredients of about 10-30%, and arrowroot flour can exchange of wheat flour commonly used in the production of bread.

Weighing the child's weight every month to find out the nutritional status of children is one of the routine activities at the Posyandu. One effort to reduce the problem of malnutrition in children is to increase the participation of mothers in visiting and weighing their children to the Posyandu every month. This study aims to determine the relationship of the number of Posyandu visits with the nutritional status of children under five (1-5 years). This study uses a descriptive correlation design with a retrospective approach. The study was conducted in the working area of the Amplas Health Center with a sample of 382 mothers and children under five years old using proportional random sampling technique based on the number of Posyandu. The measuring instrument used was a questionnaire for demographic data and a child's weight-weighing registration book. The analysis used is univariate analysis to determine the frequency distribution and bivariate analysis using chi-square. The results showed that 145 people (38%) regularly visited Posyandu and 237 people (62%) did not regularly visit Posyandu. Children who have good nutritional status are 203 people (53.1%), malnutrition is 109 people (28.5%), and malnutrition is 70 people (18.3%). The bivariate analysis results obtained p value (0.00) <ɑ (0.05), so it can be concluded that there is a correlation between the number of Posyandu visits and the nutritional status of children under five. Suggestions for puskesmas staff to be able to conduct training and health education to cadres and improve health facilities in Posyandu.

The aim of this study to classification maternal mortality in health promotion for reducing the maternal mortality rate in Dairi. The result of this study indicated the decision tree and Naïve Bayes are available to train and test the dataset. The accuracy of the decision tree of maternal mortality is 100 % and the Naïve Bayes model indicates 97.37 % of maternal mortality.

Abstract-Anemia and stunting are major public health problems, and they have a high prevalence rate in Southeast Asia. In this cross-sectional study, infants from 0 to 6 months and their mothers were investigated to determine the prevalence of stunting and anemia in infants and anemia in breastfeeding mothers. Multistage cluster was used as sampling techniquein selecting five sub districtsin Binjai City of North Sumatera Province, Indonesia. Analysis uses the information of hemoglobin levels from 100 breastfeeding infants and their mothers which have their peripheral blood tested by hemocue. Examination of anemia infants based on the levels of hemoglobin give results <14g/dL for 0-3 days of age, <13g/dL for one weekof age, <12g/dLfor 2 weeks of age, <11g/dL for 1 month of age, <10g/dL for 2-6 monthsof age. Anthropometric indicator (range-for-age ≤2SD) were measured for stunting infants. Data analysis uses chi-square test. The overall prevalence of anemia in infants was 29%, and anemia in breastfeeding mothers was 52%, while prevalence of stunting in infants was 34%. Anemia in breastfeeding mothers is not associated with infant anemia (p=0.685 > 0.05), and with stunting in infant (p=0.161 > 0.05). Hb concentration in infants were not statistically different (p=0.83) among breastfeeding mothers which are anemia (11.4±1.7 g/dL) and non anemia (11.5±2.2 g/dL). The results of this study indicate that maternal anemia during breastfeeding was not associated with anemia and stunting in infants. These results are very important as a baseline for prevention planning of stunting and anemia in children.
