This study aims to determine and analyze the combination of aeration systems with Multiple Tray Aerator and Filtration with Rapid Sand Filter in reducing iron (Fe) content in water. The source of water used is shallow well water that is still used by the community. The research design used in this study was One-Group Pretest-Posttest Design. The study located in Pangkep Regency, South Sulawesi Province, and then for the second location in Manado City, North Sulawesi Province. The number of samples with the type of experimental research was 10 with the Purposive Random Sampling technique. The instruments used in this research are Multiple Tray Aerator and Rapid Sand Filter. The results showed that the percentage of reduction using a combination of aeration and filtration systems when averaged for the two study sites, a rate of 58.50 percent obtained. The increase in iron (Fe) content, one of which is influenced by the climate at the research location, will directly increase the water temperature sources in this study, namely surface wells, which will dissolve more iron (Fe) levels. Another factor that affects iron (Fe) levels is the difference in research locations, namely on islands and coasts. This can be seen in the differences in the results of iron (Fe) levels obtained at the two research locations. Those who wish to conduct further study should pay attention to the tool's type and ability and design a more accurate model to minimize energy and cost and a more concrete form.

Undergoing relatively slower growth, infants with low birth weight (henceforth, LBW) sometimes suffer from digestive tract disorders that leads to deficiency of nutrients supply within the body. The 2018 data in Gorontalo Regency reported that 312 under-fives suffer from LBW. This study intends to analyze whether or not LBW contributes to stunting cases in 24-59 months infants in Haya-haya village, Western Limboto sub-district, Gorontalo regency. The analytical observational survey study employed cross-sectional approach. The study treated the population of all babies with LBW as the sample by total sampling technique. Moreover, it involved LBW as the independent variable and stunting as the dependent variable. The statistical test result indicates that χ2count > χ2 table with ρ value of 0.00 < 0.05; therefore, signifying that H0 is denied and Ha is accepted. All in all, there is a significant correlation between LBW and stunting cases in 24-59 months babies in the research site.

Background: The most essential aspect to reduce the number of maternal and newborn mortality is midwife competence. Midwives have a great role to be able to handle variety of health services (antepartum, intrapartum, and postpartum) to avoid or decrease the maternal and infant mortality rate. Performance of health workers, particularly midwives, is the most crucial in affecting the quality and quantity of midwives’ services to  enhance the national health development.Aim: This study analyzed factors affecting village midwife performance for reducing maternal and infant mortality in seek for achieving Bone Bolango cemerlang or bright Bone Balango as the vision of Bone Bolango District in 2021.Methods: This study was an analytical survey with a cross-sectional approach. It was conducted from March to June 2019 in the working area of Bone Bolango District Health Office. There were 227 people from 19 primary healthcare centers as the population, and the sample size was 227 selected by using the total sampling technique. The data were collected by distributing questionnaires to the respondents and using secondary data. The data processing was done through chi-square test and multiple logistic regression with backward wald method.Results: Midwife performance in Bone Bolango District was assessed based on several variables. Most of them were ≥ 25 years old (80.6%); worked for ≥ five years (58,6%); mostly had not participated in any normal childbirth care training (76.7%); had a good competence (96.5%); had good resources/equipment (79.7%); had a good reward (92.5%); had a good attitude (76.2%); had a good motivation (90.7%). There were 12 maternal mortalities from 2017 to 2019 handled by only 11 midwives (4.8%). On the other hand, infant mortality rate (IMR) reached 25 cases in the same years; of 227 midwives, these cases were handled by only 21 midwives (9.3%).Conclusion: A midwife as a part of the health workers has an important role to increase the quality of maternal and child well-being program. Some variables that became indicators of midwife performance and had an effect on reducing the MMR and IMR included work period, reward, and motivation. This study recommends that all midwives have to be provided with a normal childbirth care training in the working area and increased rewards in the process of labor and delivery. Keywords: midwives, performance, maternal mortality rate, infant mortality rate.
