Optimization of Biopore Infiltration Holes as an Environmental Conservation Effort in Graha Indah Urban Village to Support the CGH Program

Optimalisasi Lubang Resapan Biopori sebagai Upaya Konservasi Lingkungan di Kelurahan Graha Indah dalam Mendukung Program CGH

Abstract

Environmental problems in residential areas, such as reduced water infiltration and unmanaged household organic waste, are increasingly common due to urban development. This community service activity aimed to introduce biopore infiltration holes as a simple technology to support a clean, green, and healthy environmental program in Graha Indah Urban Village, Balikpapan City, using a participatory approach involving the community and neighborhood units. Activities included field observation, coordination with local leaders, environmental education, and direct implementation of biopore holes. Education was conducted for residents of two neighborhood units, attended by 40 of 50 invited participants, an 80 percent attendance rate, while implementation was carried out in four neighborhood units. Evaluation using pre-test and post-test showed that 37 of 40 participants, or 92.5 percent, achieved a good knowledge category after the education session, exceeding the program's success indicator of 80 percent. A total of 26 biopore holes were successfully installed across the four target areas. These results indicate that the program achieved its objectives, improving community understanding and practical skills in biopore construction, enhancing rainwater infiltration, and encouraging household organic waste processing into compost.
