Abstract

The population increases, leading to extensive urbanization and the consequent rise in impervious surfaces. This urbanization trend has exacerbated stormwater runoff issues, necessitating sustainable stormwater management strategies. Low Impact Development (LID) techniques, such as bioretention, have emerged as promising solutions to mitigate the adverse effects of increased impervious surfaces on stormwater management. Through drainage simulation using EPA SWMM 5.2 software, this study assessed the effectiveness of bioretention in mitigating stormwater runoff within Pesona Regency Housing in Jember Regency. In this approach, hydrological techniques use rainfall for a 2-year return period based on the typology of the study area. The bioretention scenarios used coverage of 5%, 10%, and 20% of the subcatchment area as Scenario 1, 2, and 3. The simulation revealed promising reductions in peak runoff discharge across various scenarios, with average reduction rates of 80%, 88%, and 92% for Scenarios 1, 2, and 3, respectively. However, the effectiveness of bioretention varied across different junctions and scenarios due to factors such as location, junction area coverage, soil properties, and local drainage patterns. While larger bioretention areas generally resulted in greater runoff reduction, the study underscores the importance of considering location and cost-effectiveness in bioretention design. Overall, this research provides valuable insights into the efficacy of bioretention as a stormwater management strategy in rapidly urbanizing areas, offering guidance for property developers in planning flood-resistant housing with LID bioretention.

Abstract

Sabrang Village is one of the villages in Ambulu sub-district, Jember Regency, the majority of the population make a living as farmers and ranchers.  Animals that are farmed are cows. Manure waste from cattle in Sabrang Village has not been managed and utilized properly, so if it can be managed properly, it will be able to improve the welfare of the people in the village.  This is in line with the Community Service Team program on livestock waste management and treatment to reduce environmental pollution. One that supports this program is to process livestock manure waste into something useful, one of which is an alternative fuel such as biogas. Therefore, it is necessary to increase public insight into the utilization of livestock manure waste into biogas.  This can later meet people's needs for fuel that will be useful for their lives later.
