Occurrence and visual characterization of microplastics from Mahakam River at Tenggarong City, Indonesia

Journal of Contaminant Hydrology (2024)

Indonesia generates approximately 7.8 million tons of plastic waste annually, which 4.9 million tons is mismanaged. Presently, there is significant concern on microplastics (MPs) pollution in aquatic environment. The research on the prevalence of MPs in river systems are comparatively lower than the studies conducted on marine systems. The primary goal of this research was to look into the prevalence of MPs in the river water of Mahakam of Tenggarong City, Indonesia. To adequately represent this area, a meticulous selection method was used to find five separate sampling locations, with two stations at each location, positioned 200 m apart on opposite sides of the river. According to the study's findings, MPs has been observed in the range of 19.2 ± 1.8 to 58.5 ± 3.5 particles/l. Based on the MPs type, fragments (43.4 %) were the most common type of MPs found in water samples. Furthermore, 44.6 % of the MPs had size smaller than 1000 μm. The prevalent hues observed in the water samples were transparent and black, composing 75.6 % of overall formation. The determination of microplastic polymers employed Attenuated Total Reflection-Fourier Transform Infrared (ATR-FTIR) spectroscopy, revealing the presence of various type, such as polyethylene (PE) and polypropylene (PP).

Assessing social vulnerability to flood hazards: A case study of Sarawak's divisions

International Journal of Disaster Risk Reduction (2023)

Ismallianto Isia Tony Hadibarata Ratih Indri Hapsari Muhammad Noor Hazwan Jusoh Rajib Kumar Bhattacharjya

Social vulnerability assessment to flood hazard depends upon multiple factors that can vary across the different indicators. However, there is limited knowledge on specific indicators suitable for assessing social vulnerability on Sarawak. This study systematically analyzed important components of vulnerability and mapped them by weight for the 12 different divisions. Indices focusing on components of the two different dimensions of vulnerability (physical exposure and resistances) were identified based on the literature. Data on these different indices were then collected through relevant government agencies. Components of vulnerability dimensions were assessed and significantly contributing components were identified by Principal Component Analysis (PCA). An entropy method was used to weight the dimensions of vulnerability for the different divisions. Vulnerability was estimated based on the Iyengar and Sudarshan methodology and the data were used to produce a vulnerability map based on a proposed Social Vulnerability Index (SVI). The results indicated that divisions of Kuching, Miri, Sibu and Bintulu were more vulnerable (score over than 0.81) than those in other divisions. Greater vulnerability was mainly due to high exposure to extreme events and less adaptive capacity of resistance, which can affect agricultural production negatively, in combination with high population density in communities. The map clearly shows which areas are more susceptible, indicating that the government's adaptation measures should vary depending on the available resources, urgency, and means of survival needed to achieve resilience against climate change.
