    The basin shape of Bandung limits dispersion and transport of air pollutants. This topographical characteristic causes air pollutants to be trapped and accumulated within the basin, where urban areas  were located. In the issue of of sustainable city, rainwater could be potential sources of  fresh water. However, air pollution in urban area might alter the natural rainwater composition. Characterization of rainwater was  conducted by collecting rainwater bulk samples at 4 (four) sites located in a transect from high elevation to the lowest at the base of the Bandung basin. Identification of trace metals, cations and anions were performed in rainwater collected in Bandung City during rainy seasons in February to March 2016. Acidity (pH), conductivity, anions and cations (SO42-, NO3-, Cl-, Ca2+, Mg2+, Na+, K+ and NH4+) and trace metals of Ag, Al, As, Ba, Cd, Co, Cr, Cu, Fe, Ni, Pb, Sb, Se, Sn, Sr and Zn were analysed. During the sampling period,  the rainfall rate ranged between 19.02 mm/week to 130.48 mm/week. The results show that rainwater pH were 4.10 – 5.95. The dominant chemical composition of rainwater were sulfat (37% – 39%) and ammonium (17% - 26%), followed by nitrate. The trace metals analyses indicated that lead (Pb) had the highest concentration (mean = 76.68 ”g/L). The concentration of the trace metals decreased in order of Pb, Fe, Zn, Al, Se, Cu, As, Ba, Co, Sr, Ni, Cd, Cr, Sn and Sb. Lead is a toxic compound, resulting from human activities, such as fossil fuel burning, mining and manufacturing. The initial analysis of rainwater composition including heavy metals suggested that rainwater contain various and potential harmful substances, including heavy metals. These findings are particularly important  and should be taken into consideration in the context of  rainwater as a water sources in urban area, e,g. rainwater harvesting for the domestic purposes and urban farming

    Autism is a disorder of pervasive development in children, which until now,the exact cause is unknown. The strongest allegations are genetic andenvironmental factors, especially heavy metals. This study aims to look therelationship between the occurrence of heavy metals pollution with theautism cases in Samarinda and Bantul. This study was carried out bymeasuring the levels of heavy metals in fish, vegetables, water and soil andalso hair of 30 autistic children and 10 control children in Samarinda and 30autism 4 control in Bantul.All samples were measured their heavy metalcontent (As, Hg, Cd, Pb) at The Central Nuclear Applied Science andTechnology Laboratory in Bandung. The result compares with the standardvalue and were found that the samples was exceeding the heavy metals valuein Samarinda is Arsenic in fish, lead in fish. While in Bantul, Mercury in fish,mercury in vegetable and lead in vegetable. In the hair samples result, thelevel of arsenic, mercury and lead were higher in autism children comparedto controls in Samarinda, while in Bantul only mercury and lead levels arehigher in hair of autism children than controls. Cadmium levelswere nodifference between autistic and control hair both in Samarinda and Bantul

    Effect of Community Education on Community Knowledge of Premature Rupture of Membranes

    Get PDF
    Premature rupture of membranes (PROM) is still a health problem with a reasonably high incidence among pregnant women in Indonesia. The PROM is defined as the rupture of membranes before signs of labor are observed. Better knowledge on the causes, signs, symptoms, and complications of PROM is believed to help in reducing maternal and infant mortality caused by PROM. This was a cross-sectional, analytic observational study conducted in Cipacing Village, Sumedang, West Java, Indonesia during the period of June-July 2022. . Community education was held to give better knowledge about PROM for women with an obstetric and gynecology specialist and fetomaternal consultant as the resource person. Total sampling was obtained from 62 women. Data were collection using pre-test and post-tests before and after the education session. The mean pre-test score was 6.48, while the mean post-test score was 7.96. A dependent T-test was used to determine the relationship between scores before and after the community education with a p-value of 0.0001. There was a significant increase in knowledge about PROM after the education session compared to before the session. This means community education is effective and impactful to increase the level of knowledge about PROM among women

    The Influence of Heavy Metal Levels on Autism Case in Bontang and Samarinda City, East Kalimantan – Indonesia

    Autism is a disorder of pervasive development in children, which until now, the exact cause is unknown. The strongest allegations are genetic and environmental factors, especially heavy metals. To observe the influence of the environment (heavy metals) on the incidence of autism in two cities located in East Kalimantan (Bontang and Samarinda). measurements of heavy metal levels were carried out in each of the 30 autistic children and 10 control children respectively. Furthermore, with a case control study design, a comparison between the levels of heavy metals in autistic patients' hair and hair control was done. Also by measuring the levels of heavy metals in shells, fish, vegetables, water and soil and comparing the results with heavy metals in the hair. As the results, the levels of arsenic (As), mercury (Hg) and lead (Pb) were higher in autism children’s compared to controls, but cadmium (Cd) levels were no difference between autistic and control hair, both in Samarinda and Bontang. Likewise, in environmental samples (shellfish, fish, vegetables, water and soil) there was an elevation of As, Hg, and Pb levels in  some samples which corresponded to As, Hg and Pb levels in autistic sufferers' hair, but there were no environmental samples were found to have high levels of cadmium. This is also in accordance with the cadmium levels in sufferers'hair and control. High levels of heavy metals detected  in children with ASDs at two cities in East Kalimantan indicate a correlation with environmental exposure. Further comprehensive investigations are recommended to assess environmental hazards at this location

    Cryptic diversity of a widespread global pathogen reveals expanded threats to amphibian conservation

    This work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License.Biodiversity loss is one major outcome of human-mediated ecosystem disturbance. One way that humans have triggered wildlife declines is by transporting disease-causing agents to remote areas of the world. Amphibians have been hit particularly hard by disease due in part to a globally distributed pathogenic chytrid fungus (Batrachochytrium dendrobatidis [Bd]). Prior research has revealed important insights into the biology and distribution of Bd; however, there are still many outstanding questions in this system. Although we know that there are multiple divergent lineages of Bd that differ in pathogenicity, we know little about how these lineages are distributed around the world and where lineages may be coming into contact. Here, we implement a custom genotyping method for a global set of Bd samples. This method is optimized to amplify and sequence degraded DNA from noninvasive skin swab samples. We describe a divergent lineage of Bd, which we call BdASIA3, that appears to be widespread in Southeast Asia. This lineage co-occurs with the global panzootic lineage (BdGPL) in multiple localities. Additionally, we shed light on the global distribution of BdGPL and highlight the expanded range of another lineage, BdCAPE. Finally, we argue that more monitoring needs to take place where Bd lineages are coming into contact and where we know little about Bd lineage diversity. Monitoring need not use expensive or difficult field techniques but can use archived swab samples to further explore the history—and predict the future impacts—of this devastating pathogen
