Abstract

Sungai Sringin berada di wilayah Semarang Timur, Kecamatan Genuk merupakan daerah yang bertopografi rendah dan berbatasan langsung dengan laut Jawa. Perkembangan industri, perdagangan, pelabuhan, serta pertumbuhan penduduk yang cepat sebesar 2,84% per tahun (BPS Kota Semarang, 2021) menjadikan kawasan Semarang Timur khususnya Kecamatan Genuk sebagai pusat pertumbuhan utama. dan terminal jasa distribusi. Hal ini akan mempengaruhi daerah Sungai Sringin sebagai daerah tangkapan air. Pada 6 Februari 2021 telah terjadi limpasan air permukaan di beberapa wilayah Sub Das Sringin dikarenakan intensitas hujan yang tinggi serta berkurangnya daerah infiltrasi air hujan yang ada. Maka dari itu diperlukan metode LID untuk mengurangi limpasan air permukaan. Dari pemodelan yang di lakukan menggunakan Software Strom Water Management Model (SWMM) di dapat bahwa puncak limpasan air permukaan tertinggi berapa pada Subcatchment 6 dengan nilai 23.10 m3/s. Untuk mereduksi limpasan air perumakaan yang ada digunakan metode pembangunan berdampak rendah. Metode pembangunan berdampak rendah (LID) merupakah cara mengelola air hujan dalam skala mikro terutama pada kawasan tangkapan air hujan yang besar. Pada penelitian ini digunakan metode Rain Barrel, Bioretention Cell, dan Infiltration Trench yang merupakan contoh dari penerapan pembangunan berdampak rendah. Hasil dari pemodelan dengan menggunakan ketiga metode tersebut didapatkan pada nilai limpasan air permukaan mengalami penurunan

Abstract

Flood disasters in Indonesia are persistent challenges during the rainy season, primarily due to intense rainfall and inadequate flood control. This study evaluates hourly rainfall to characterize hydrology and predict flood discharge more accurately, benefiting water infrastructure planning. The research used modified Mononobe methods, observational data, and rainfall-runoff modeling, including HEC-HMS simulations with the SCS-CN unit hydrograph. Observed rainfall simulated a flood discharge of 779.7 m³/s, while empirical rainfall yielded 3623 m³/s, showing a 79.12% deviation. Comparing flood hydrographs, recorded rainfall data closely matched previous studies (R² = 0.94), unlike empirical rainfall (R² = 0.88). The study concludes that observed rainfall is highly effective for estimating flood runoff, accurately representing local characteristics. This method significantly aids planning and design of water resource infrastructure like dams, weirs, and bridges at the study site.

Abstract

The increasing need for food due to population growth demands the optimization of dry land through efficient irrigation strategies. One approach is the selection of alternative crops with low water requirements but high economic value. This study aims to assess the potential of the KK-09 water spinach variety as an alternative cropping pattern in optimizing dry land irrigation. The method used is a literature review based on the Scopus database with relevant keyword searches and topic mapping using the Vos viewer tool. A total of 70 articles related to irrigation optimization in dryland were identified. In addition, an analysis of water requirements was conducted based on plant growth phases (germination, vegetative, flowering, and ripening). The results show that KK-09 water spinach only requires ± 720 mm of water in one planting cycle (110 days), with an average discharge requirement of ± 0.069 liters/second/hectare. The economic water efficiency reaches IDR 68/mm and a profit of IDR 100,400/m³, making it superior to other secondary crops such as corn, sorghum, and mung beans. These findings indicate that the KK-09 variety has the potential to be a sustainable irrigation solution for areas with limited water availability.
