Abstract

Flooding has become one of the recurring environmental problems affecting residential areas in Samarinda City, with significant repercussions across multiple dimensions of community life. This study was designed to examine how residents perceive the impacts, triggering factors, and flood mitigation measures undertaken in the Haji Saleh Housing Complex, Loa Janan Ilir Subdistrict. A descriptive quantitative method was employed using a Likert-scale questionnaire (1–5). A total of 40 respondents were selected through purposive sampling, with an age criterion of 15–64 years. Data were analyzed using mean values. The findings reveal that all measured indicators fell within the high to very high categories, yielding an overall mean score of 4.42. Respondents identified heavy rainfall as the primary triggering factor of flooding (mean 4.68), while inadequate drainage capacity also contributed significantly (mean 4.65). The most dominant impacts were property damage (4.60) and mobility disruption (4.53). Meanwhile, community-based flood mitigation efforts were categorized as high. These results indicate that residents possess a strong flood risk perception, underscoring the need for strengthened collaboration between government and community in sustaining mitigation efforts and improving drainage infrastructure on an ongoing basis.

Abstract

Soybean wastewater contains high levels of organic pollutans, such as high COD, TSS, and TDS values. This study aims to evaluate the effectiviness of phytoremediation using two aquatic plants species, Salvinia molesta and Azolla pinnata, in reducing pollutant levels in soybean wastewater. The experiment was conducted in a batc system using 10-liter plastic conyainers filled with 5 liters of soybean wastewater and 200 grams of each plant spesies. The study was cinducted over 7 days with samples taken on days 1, 3, and 7. The parameters measured included temperature, pH, dissolved oxygen (DO), total suspended solids (TSS), total dissolved solids (TDS), and chemical oxygen demand (COD). The results showed that Azolla pinnata significantly reduced COD levels by 65,91%. Overall, phytoremediation using Azolla pinnata demonstrated higher efficiency in improving water quality and could serve as a cost-effective and environmentally friendly treatment option for soybean wastewater.
