  The amount of exhaust emissions resulting from the burning of motor vehicles caused the air in the city of Makassar to be polluted. This study aims to estimate the concentration of Sulfur dioxide (SO2) and Nitrogen dioxide (NO2) for 10 years (2017-2027) on the main road of Makassar city. This research is an observational analytic research with dynamic system model approach. Results showed that in the next 10 years, the estimated total concentration of total Sulfur dioxide (SO2) in the first scenario without do nothing in 2017 of 6.44 μg/Nm3 increased by 2027 by 8,581 μg/Nm3 by multiples of increased concentration 61.58 times/month and an annual increase of 1.80 times/year whereas the estimated concentration of Nitrogen dioxide (NO2) in the absence of control measures increased from 2017 by 4.99 μg/Nm3 increased by 2027 by 7,934 μg/Nm3 by multiples of increased concentration 37.6 times/month. Application of Second Scenario (2) has decreased total concentration of Sulfur dioxide (SO2) and Nitrogen dioxide (NO2) when compared to total concentration in first scenario (I). Increasing the concentration of Sulfur dioxide (SO2) in 2017 by 6.44 μg/Nm increased by 2027 by 3785 μg/Nm3 with total monthly concentration increase of 37.4 times/months and total annual concentration increase of 0.72 times/year. Effectiveness in the second scenario in reducing the concentration of Nitrogen dioxide (NO2) by 22.72%. Application of the third scenario (3) there is a significant decrease in the concentration of sulfur dioxide and nitrogen dioxide when compared to the first scenario (1). Effectiveness in the third scenario (3) in reducing sulfur dioxide concentration of 66.43%. Implementation of the fourth scenario (4) passenger shift for the use of bus rapid transportation (bus rapid transportation) with the aim of decreasing the volume of vehicles operating on the main road, if it is assumed that 50% of passengers switch to BRT bus, BRT passengers in 2027 will be 3960/days.

  The vigorous campaign of complementary feeding in both society and in the hospital, as well as through electronic media (radio and TV) and newspapers, makes many mothers interested in providing their children with early complementary feeding. In addition, stay-at-home mothers’ duties and the customs and traditions of the community are also driving factors in giving children early complementary feeding. In 2008, Azrul Azwar stated that complementary feeding should be granted gradually to infants to suit their digestive development. This study aims to assess the differences in media exposure and family support regarding the provision of appropriate complementary feeding in a group of working and stay-at-home mothers. Our cross-sectional study used a sample size of 121 women, divided into groups of 76 working mothers and 45 mothers who do not work outside the home. Based on the results of multivariate statistical tests using Hotelling’s T2 test, we obtained F values of 5.813 and p values of 0.004 (p<0.05). This means that there are significant differences in family support and media exposure regarding the provision of appropriate complementary feeding in infants zero to six months of age between working mothers and stay-at-home mothers. It was recommended that the government, in this case, the Center of Health, appeal to the media to provide proper information to the public, primarily to working mothers who did not give complementary feeding early. Families also need an explanation about the right time to provide complementary feeding so as not to risk infant health.
