Tangerang City has an increasing population with an annual average of 1.87% between 2009-2019. Increased space requirements, leading to land function changes. The conversion of land use will change the built-up and the vegetation index will affect green open spaces. If it does not support properly, there will be less green open space in Tangerang City. The purpose of the research is to examine implied changes in the built-up and the vegetation index on green open space in Tangerang City. The analysis will be carried out by built-up index, and vegetation index carried out in 2009, 2014, 2019. The analysis is carried out to determine the distribution of the built-up and the vegetation index in the City of Tangerang, so that it can be seen which locations dominated by class distribution high and very high vegetation density. The density class is the assumption that represents green open space. Based on the analysis of the results, the green open space of Tangerang City is less than 30%. So, implications are related to the need for green open space in Tangerang City. The government has implemented the green open space development that has been carried out in the Tangerang City RTRW 2012-2032.

Background: The lack of folic acid and zinc intake has considerable impact on both mother and fetus, and based on this research, the intake of folic acid and zinc among pregnant women in West Java is still quite low.Objective: The purpose of this research was to know the intake and average of folic acid and zinc among pregnant women in West Java.Methods: The method of this research was descriptive using cross sectional research design, and the sample was selected by using total sampling method from research of Academic Leadership Grant (ALG) on all first trimester pregnant women as many as 176 respondents who lived in the city of Sukabumi, Cirebon, Bandung and Cimahi recruited in the period of July 2016 - February 2017. Data source was the secondary data from food diary. The analysis used univariate data.Results: Most of the respondents with the folic acid intake not fulfilled were 97,2% and most of them with the zinc intake not fulfilled were 96%, with the average of folic acid intake 163 μg/day and the average of zinc intake 5,1 mg/day.Conclusion: Most of the respondents are categorized in the not fulfilled folic acid and zinc intake with the average under the Recommended Dietary Allowances (RDA) for pregnant women.

In Indonesia, especially Bandung, there are still many cases of maternal deaths during pregnancy, birth, and postpartum which can increase the Maternal Mortality Rate (MMR). Cases of maternal deaths are mostly due to exsanguination, infection, anemia, and the other causes that related to pregnancy. To reduce the MMR of Bandung, we can analyze to determine the factors that influence the MMR in order to maximize the maternal health care programs so as to prevent the possibility of death. The analysis is using Zero-Inflated Poisson (ZIP) regression because maternal mortality data is the result of counting that allows overdispersion due to excess zeros. Regression parameter estimation use expectation maximization algorithm followed by the Newton-Raphson iteration method. The analysis result showed that of the five suspected factors to affect the MMR -such as the first tetanus toxoid immunization (TT1), the provision of 90 Fe tablets (Fe3), postpartum care, pregnancy complications, and the first antenatal care (K1)- only TT1 and postpartum care are significantly affect the MMR.
