Endah Lestari officially earned her Doctorate in Civil Engineering after successfully defending her dissertation during the Open Doctoral Promotion Session held on Wednesday (16/07/2025) at Untar Campus I, Jakarta.
In her dissertation titled “Application of Hybrid Infrastructure Based on Low Impact Development (LID) for Surface Runoff Reduction (Case Study: Tanjung Priok, Koja, and Kelapa Gading Districts, North Jakarta),” Dr. Endah examined solutions for urban rainwater management through a sustainable drainage approach that combines grey infrastructure and green infrastructure methods.
This research stems from issues arising due to massive urbanization in North Jakarta. The increase in built-up areas and the reduction of water absorption zones have caused a sharp rise in surface runoff, resulting in localized flooding and waterlogging. Conventional drainage systems are considered no longer adequate to address these challenges.
As a lecturer in the Civil Engineering Program, Faculty of Infrastructure Technology and Regional Planning at Institut Teknologi PLN, Dr. Endah explained that the Low Impact Development approach based on hybrid infrastructure aims to reduce runoff volume, increase water infiltration, and maintain groundwater sustainability in densely populated areas.
“Through this approach, I hope the research results can provide concrete solutions to strengthen urban drainage systems that are more adaptive and environmentally friendly, especially in urban areas like North Jakarta,” said Dr. Endah.
The doctoral promotion session was chaired by the Rector of Untar, Prof. Dr. Amad Sudiro, S.H., M.H., M.Kn., M.M., with the main promoter Prof. Dr. Ir. Dede Rohmat, M.T., Pma-SDA, and co-promoter Dr. Ir. Wati A. Pranoto, M.T. The examination panel consisted of Prof. Dr. Ir. Agustinus Purna Irawan, M.T., M.M., IPU., A.E., Prof. Dr.-Ing. Ir. Agus Maryono, IPM., ASEAN Eng., Ir. Harto Tanujaya, S.T., M.T., Ph.D., and Ir. Oei Fuk Jin, S.T., M.Eng., D.Eng.
This research also contributes to the achievement of the Sustainable Development Goals (SDGs), particularly SDG 6 (Clean Water and Sanitation), SDG 11 (Sustainable Cities and Communities), and SDG 13 (Climate Action). The dissertation also refers to national policies related to rainwater utilization, such as the Minister of Environment Regulation No. 12 of 2009 and the Ministry of Public Works and Public Housing Regulation No. 11/PRT/M/2014.
With her graduation, Dr. Endah becomes the 93rd doctoral graduate from Untar’s Doctoral Program in Civil Engineering. Her scholarly work is expected to serve as an important reference in planning more efficient and sustainable urban drainage systems amid the challenges of climate change and urbanization. (VC/AJ)
