Vision DEDIKASI 2025 was a national competition aimed at finding the best innovations in water resources management and sustainable infrastructure development. The event drew participation from numerous prestigious universities across Indonesia, with the main challenge centered on creating sustainable solutions to improve societal welfare.

The Minasunwin Team, comprising Mochamad Reynald Purnama Dewa, Faizunisa Thahir, and Achmad Fahrezi, delivered an exceptional performance right from the preliminary round, successfully achieving the highest paper score. They carried this momentum into the final round in Makassar, where they outperformed teams from other universities with their outstanding presentation.

The flood and water crisis in the Maros District prompted the team to present the Integrated Nature-Based Smart Drainage System, a solution that combines smart technology with a nature-based approach. This system consists of three primary integrated components: rainwater harvesting, a smart drainage system, and a smart retention pond.

As the name suggests, rainwater harvesting serves to collect and filter rainwater from gutters prior to the main reservoir. This component is equipped with an ultrasonic sensor that measures water levels to prevent overflow. Filtered water is then either distributed to the ground to enhance natural filtration or flowed to drainage.

Meanwhile, the smart drainage system functions as an enclosed drainage channel that effectively minimizes puddles and improves environmental quality. It is equipped with a trash rack to prevent damage to the channel, a control tank, and an electrode sensor, allowing it to detect and prevent sedimentation and blockage in the water channel.

Lastly, the smart retention pond temporarily stores water before it is discharged into rivers. This pond not only holds rainwater from the drainage system but also features a water treatment plant to process the water before it is distributed to nearby homes. To prevent overflow, the pond is equipped with an automatic sensor that activates the watergate when water levels exceed a certain threshold, ensuring a well-regulated water flow.

From Vision DEDIKASI 2025, the Minasunwin Team learned that realistic, applicable, and relevant innovations are needed to answer real-world challenges. Although the location of interest was located far away, they successfully completed their study by using long-range remote area analysis.

They revealed that it is necessary that the proposed innovation align with the aims and objectives, which was also a key factor in their success.

According to the team, their precision in designing a solution that directly addressed the problem statement earned them the champion title. "We learned that a good innovation must be implementable in the real world," said one team member. As a token of appreciation, they expressed their gratitude to fellow WREM colleagues from the Class of 2021; their advisor, Faizal Immaddudin Wira Rohmat, S.T., M.T., Ph.D.; and the Chairman of WREM, Dr. Eng. Arno Adi Kuntoro, S.T., M.T., for their continued support and guidance throughout the competition.
