Pelatihan Pembuatan Biopori Untuk Antisipasi Banjir Di Bumi Perkemahan Cadika Gedung Johor Kota Medan

Abstract

Kegiatan Pengabdian Kepada Masyarakat (PKM) ini bertujuan meningkatkan pengetahuan dan keterampilan peserta dalam memanfaatkan teknologi lubang resapan biopori sebagai upaya mengantisipasi genangan dan banjir serta mengelola sampah organik di Bumi Perkemahan Cadika Gedung Johor, Kota Medan. Permasalahan yang dihadapi di lokasi kegiatan meliputi rendahnya pemahaman mengenai manfaat biopori, kurang optimalnya pemanfaatan sampah organik berupa dedaunan, rumput, dan ranting pohon, serta keterbatasan pengetahuan dan keterampilan dalam pembuatan biopori. Metode pelaksanaan kegiatan menggunakan ceramah, diskusi, coaching, dan praktik langsung dengan proporsi 30% teori dan 70% praktik. Kegiatan diikuti oleh sekitar 45 peserta dan dilaksanakan melalui tahapan pemberian materi, diskusi dan tanya jawab, serta praktik pembuatan biopori di sekitar area danau mini Cadika. Hasil kegiatan menunjukkan adanya peningkatan pemahaman peserta mengenai sampah organik, siklus air dan banjir, manfaat biopori, serta teknik pembuatan biopori. Penerapan biopori juga memberikan alternatif pemanfaatan sampah organik menjadi kompos, membantu meningkatkan resapan air ke dalam tanah, serta mendukung kesehatan tanah dan perakaran tanaman. Kegiatan ini diharapkan dapat mendorong penerapan biopori secara berkelanjutan sebagai salah satu upaya sederhana dalam pengelolaan lingkungan dan pengurangan risiko genangan di kawasan Cadika.

This Community Service (PKM) activity aimed to enhance participants' knowledge and skills regarding the use of biopore infiltration hole technology to mitigate water pooling and flooding, as well as to manage organic waste at the Cadika Gedung Johor Campsite in Medan City. Issues identified at the site included a lack of understanding regarding the benefits of biopores, suboptimal utilization of organic waste (such as leaves, grass, and twigs), and limited knowledge and skills in constructing biopores. The activity employed a combination of lectures, discussions, coaching, and hands-on practice, with a ratio of 30% theory to 70% practice. Approximately 45 participants took part in the program, which consisted of material presentation, discussions and Q&A sessions, and practical biopore construction around the Cadika mini-lake area. The results demonstrated an improvement in participants' understanding of organic waste, the water cycle and flooding, the benefits of biopores, and construction techniques. The implementation of biopores offers an alternative method for converting organic waste into compost, facilitates groundwater infiltration, and supports soil health and plant root development. This activity is expected to encourage the sustainable adoption of biopore technology as a simple yet effective measure for environmental management and flood risk reduction in the Cadika area.
