Pengenalan Lubang Resapan Biopori Sebagai Upaya Warga Kawasan Padat Penduduk Mengatasi Banjir Limpasan Air Hujan

Biopore infiltration holes function to help rainwater run-off to immediately enter the ground. Biopore infiltration holes have many benefits, one of which is to prevent flooding because it acts as a place for water absorption, as well as a groundwater reserve. In the Community Service Activity, the PKM team from the Faculty of Engineering and Informatics UPGRIS conducted socialization and training on the creation and installation of biopore infiltration holes for residents in the RT 1 RW 7 area of ​​Kampoong Sampangan, Semarang City. The reason for choosing it is because Sampangan is an area that meets the criteria for installing biopores, namely: densely populated settlements, has quite high rainfall, has the character of permeable soil conditions; and during heavy rains, rainwater runoff begins to inundate roads and other surfaces even though the rain has stopped for a long time. The creation of biopore infiltration holes has been proven to help overcome rainwater runoff by absorbing it into the ground, and can reduce runoff and waterlogging. Residents of RT 1 RW 7 have seen the benefits directly because areas that are usually flooded now dry quickly. Vegetable gardens and medicinal plant gardens are very suitable for installing biopore holes because besides providing water reserves, cleaned leaf and plant waste can be directly put into the biopore holes.
