Abstract

Banjir adalah salah satu bencana alam yang sering melanda Indonesia, khususnya di wilayah perkotaan seperti Kota Semarang yang menempati peringkat kedua jumlah bencana di Jawa Tengah. Salah satu penyebab utama banjir di Semarang adalah Banjir Kanal Timur (BKT), yang meskipun dibangun sebagai infrastruktur pengendali banjir, kini menunjukkan penurunan kapasitas akibat sedimentasi, penurunan muka tanah, kenaikan permukaan laut, dan buruknya pengelolaan drainase. Kejadian banjir terbaru, termasuk banjir pada Maret 2024 dengan genangan hingga 70 cm, menunjukkan perlunya perencanaan pengendalian banjir yang komprehensif. Penelitian ini bertujuan untuk menganalisis debit banjir rancangan dengan menerapkan metode Hidrograf Satuan Sintetik (HSS) Nakayasu, memodelkan perilaku banjir menggunakan perangkat lunak HEC-RAS 6.3 pada kondisi eksisting, serta merancang upaya pengendalian banjir berupa normalisasi sungai dan perencanaan tanggul sepanjang 14,70 km kanal. Penelitian menggunakan data curah hujan 10 tahun dari empat stasiun serta data pasang surut dari Stasiun Meteorologi Tanjung Emas. Hasil studi ini diharapkan memberikan gambaran teknis mengenai zona rawan banjir, strategi mitigasi berbasis simulasi, serta estimasi biaya awal penanganan. Penelitian ini berkontribusi pada pengembangan strategi pengendalian banjir yang berkelanjutan di Kota Semarang.

Abstract

SMP Negeri 11 Malang is an Adiwiyata (environmentally oriented) school that still faces environmental challenges, including excessive use of clean water, damaged and soil-covered biopores, and suboptimal waste management. These conditions indicate limited awareness and pro-conservation behavior among students, particularly regarding water resources. A Community Service (PkM) team from Universitas Brawijaya implemented an integrated water conservation education program using a participatory approach to improve students’ literacy and behavior toward water resources and the school environment. The program consisted of three core activities: (1) socialization on the importance of clean water and water-saving behavior; (2) maintenance of biopores and education on 5R principles (Reduce, Reuse, Recycle, Replace, Replant), accompanied by the development of a “waste lifespan” information board; and (3) installation of a simple rainwater harvesting (RWH) system and drip irrigation in the school garden. The methods combined interactive presentations, discussions, field practice, educational games, and evaluation through simple pre- and post-tests. The results showed that students’ comprehension score reached 85%, while in the technical aspect of biopore maintenance, 6 out of 10 treated biopore points functioned effectively again. The initial survey also indicated that approximately 95% of the school’s biopores were nonfunctional, making maintenance a priority intervention in this program. In addition, the program produced environmental educational media and a functioning RWH and drip irrigation system as appropriate technology within the school. The school expressed its commitment to sustaining and integrating this program into regular Adiwiyata activities, highlighting its potential to strengthen a school-wide culture of environmental conservation.
