Insufficient knowledge about the decomposition of microplastics from plastic waste in landfills hinders community involvement in waste management and sorting, posing a new threat to the environment and public health. The present study identifies, characterizes, and quantifies the microplastics in landfills soil sample to determine the latest threats posed by microplastics in the environment, particularly in landfills that are close to residential areas. This research is a descriptive study, with soil samples taken from six points in landfill site in Depok City. The abundance and shape of microplastics were characterized using a microscope, while the microplastic types were identified using Fourier Transform Infrared Spectroscopy (FTIR). The results showed that the abundance of microplastics in the Depok City landfill soil was 60,111.67 particles/kg, with the largest percentage being fragments at 63 %. FTIR functional group characterization showed the presence of plastic types, such as Polyethylene (PE), Polyvinyl Chloride (PVC), Polystyrene (PS), Polypropylene (PP), Polyethylene Terephthalate (PET), and Polyamide. The differences in waste types entering the Depok Landfill caused variations in the number, shape, and type of microplastic samples, and this study provides a foundation for mitigating and biodegrading microplastics in the landfill to minimize environmental impact and protect public health.

Introduction: Stunting, or linear growth failure, is defined by a height-for-age z-score of below -2SD according to WHO growth standard. Stunting can have short-, medium-, and long-term consequences. Rivers have an important role in human life. In several riverside areas, households still depend on the river for their livelihoods and health. This study aimed to explore the prevalence of stunting in children living by the riverside and its related factors. Methods: Epidemiological studies published from PUBMED, MEDLINE via EBSCOHost, Science Direct, ProQuest, and Research Gate databases were systematically searched. The publication period was not restricted. Only open-access and English articles were examined. Results: A total of 20 from 1200 studies were reviewed. The prevalence of stunting ranged from 20% to 48.3%. The other outcomes besides stunting were wasting and underweight status. There were 83 risk factors studied, and the most studied variables were age, gender, diarrhoea, water source, parent’s education, immunisation, and inappropriate complementary feeding practices (6 to 13 studies). Household water sources from rivers and economic status were consistently correlated with stunting. Majority of the risk factors studied were related to nutrition. From the environmental aspect, the most studied risk factors were water sources and sanitation. Conclusion:
Children living by the riverside face a significant risk of stunting attributed to the consistent correlation between household water sources from rivers and economic status, affecting various aspects of daily life beyond drinking water. Future research is needed to examine the impact of environmental factors and the behaviours of riverside communities.
