Abstract

This study aims to analyze the capacity of the Cijangkelok River downstream in facing the planned flood discharge, with a hydraulic modeling approach using HEC-RAS software. Maximum daily rainfall data from five rainfall stations during the 2014-2023 period was used as the basis for calculating flood discharge using the Rational method and Nakayasu Synthetic Unit Hydrograph (HSS). The calculation results showed that the peak flood discharge for the 10, 25, and 50-year return periods reached 599.71 m³/det, 648.91 m³/det, and 682.82 m³/det using the Rational method, and 835.01 m³/det, 888.68 m³/det, and 922.90 m³/det using the Nakayasu HSS method, respectively. Flow simulations with HEC-RAS indicated that some river cross sections, especially at STA 27+950, 28+050, and 28+100, were unable to accommodate the maximum discharge, causing runoff outside the channel. This finding indicates that the capacity of the existing channel is not adequate to safely channelize flood flows. The results of this study are expected to serve as a technical reference in river normalization planning and more targeted and sustainable flood mitigation efforts.

Abstract

This study analyzed the performance of the Seuseupan Irrigation Area in Cirebon Regency using the E-PAKSI application. The research employed a descriptive-qualitative method with both primary and secondary data collection. The results revealed a combined main and tertiary irrigation system performance index of 57.62%, which falls into the underperformance category. Water discharge analysis indicated sufficient supply for the rice-rice cropping pattern across the 1,347-hectare service area. However, institutional aspects and personnel were found to be non-compliant with regulations. Furthermore, there was a significant increase in maintenance costs (AKNOP), rising from Rp2.31 billion in 2022 to Rp22.33 billion in 2024. This highlights the critical need for serious attention to the management of irrigation assets and infrastructure in the region.

Abstract

Desa Kanci di Kecamatan Astanajapura, Kabupaten Cirebon, memiliki program Kuliah Kerja Nyata (KKN) yang bertujuan untuk mengoptimalkan potensi pertanian dengan menerapkan smart watering system. Meskipun Desa Kanci memiliki banyak lahan pertanian, sebagian besar masih bergantung pada tadah hujan, sehingga sering terjadi kekeringan selama musim kemarau. Kondisi ini menyebabkan produktivitas lahan menurun. Kegiatan pengabdian dilakukan dengan pendekatan partisipatif dan melibatkan mitra utama seperti Gabungan Kelompok Tani (Gapoktan), Kelompok PKK, pemerintah desa, dan 13 mahasiswa Universitas Swadaya Gunung Jati Cirebon yang didampingi oleh satu dosen pembimbing lapangan. Di lahan percontohan, tim dosen dan mahasiswa melakukan hal-hal seperti sosialisasi, pelatihan, instalasi teknologi, dan pendampingan penggunaan sistem air pintar. Untuk meningkatkan kapasitas ekonomi keluarga, kelompok PKK juga menerima pelatihan tentang pengembangan usaha mikro dan manajemen sederhana. Hasil kegiatan menunjukkan peningkatan pemahaman dan keterampilan mitra dalam mengelola teknologi pengairan kontemporer, peningkatan efisiensi penggunaan air, dan komitmen mitra untuk mempertahankan dan mengembangkan teknologi secara mandiri. Sementara PKK lebih aktif terlibat dalam kegiatan ekonomi produktif, gopoktan yang sebelumnya hanya berfokus pada padi mulai mencoba berbagai jenis tanaman hortikultura. Mahasiswa membantu masyarakat dalam pelaksanaan dan dokumentasi program, dan pemerintah desa memberikan dukungan administratif dan fasilitasi. Secara keseluruhan, masyarakat Desa Kanci telah berhasil meningkatkan kemampuan mereka dalam bidang pertanian dan pemberdayaan ekonomi dan menjadi model penerapan teknologi tepat guna berbasis partisipasi masyarakat untuk pembangunan desa yang berkelanjutan melalui program kerja keras.
