Abstract

Abstrak Sebagai kampus baru, pembangunan infrastruktur Institut Teknologi Sumatera (ITERA) disegala sektor terus dilakukan demi upaya menunjang proses pembelajaran, namun berdampak pada perubahan alih fungsi lahan sehingga daya resap air semakin berkurang dan limpasan air permukaan semakin meningkat, sehingga perlu dilakukan perencanaan drainase yang terintegrasi dengan pembangunan. Perencanaan drainase meliputi analisis curah hujan, pengukuran lapangan dan perhitungan dimensi saluran serta simulasi pada software HECRAS. Metode rata-rata aljabar digunakan untuk analisis curah hujan wilayah dengan distribusi log pearson III. Dimensi saluran berupa persegi dengan lebar 0,56 m dan tinggi 0,73 m. Adapun debit saluran 0,53 m3/det dengan metode rasional, sedangkan total biaya perencanaan drainase sepanjang 1282,1 m ini sebesar Rp. 1.107.523.000 (Satu Milyar Seratus Tujuh Juta Lima Ratus Dua Puluh Tiga Ribu Rupiah). Dengan terbangunnya drainase diharapkan mampu mengalirkan limpasan air permukaan yang terjadi. Kata Kunci: ITERA, Drainase, Debit, HEC-RAS  Abstract As a new campus, the infrastructure development of the Sumatera Institute of Technology (ITERA) in all sectors continues to support the learning process, however it has an impact on changes in land use so that water absorption capacity is decreasing and surface runoff is increasing, so it is necessary to carry out drainage planning that is integrated wit development. Drainage planning includes analysis of rainfall, field measurements and calculation of channel dimensions as well as simulations on the HECRAS. The aljabar method is used for the analysis of regional rainfall with a pearson III log distribution. The dimensions of the channel are square with widht of 0,56 m and height of 0,73 m. the channel discharge is 0,53 m3/s using the rational method. While total cost of drainage planning along the 1282,1 m is Rp 1.107.523.000, (one billion one hundred seven milion five hundred twenty three thousand rupiah). With the construction of the drainage is expected to be able to drain the surface runoff that occurs. Keywords: ITERA, Drainage, Discharge, HEC-RAS

Abstract

Analysis of unmeasured flow rates in watershed with the Syntetic Hydrograph Unit (SUH) Method is the most practical and simple method. This method requires watershed characteristics as river length and watershed area. Calculation and flow rate data are very useful in the development of water resources science and civil building planning especially in water construction work. Today, the Syntetic Unit Hydrograph (SUH) Method has been widely developed and most recently the ITB-1 Syntetic Unit Hydrograph (SUH) Method. The reliability of SUH ITB-1 in Sungai Tapung Kanan and Sungai Tapung Kiri shows good performance. This is indicated by the accuracy of the volume of the Tapung Kanan River 96.30% and the accuracy of the Tapung Kiri River 99.88%. The volume control ratio / direct run off (DRO) Sungai Tapung Kanan 1,00006 and Sungai Tapung Kiri 1,000088 (close to 1). While the peak discharge produced by Tapung Kanan River is 39,950 m3/ sec and Tapung Kiri River is 38,867 m3/sec.

Abstract

Floods are always a problem, especially in residential areas. This is in line with the development of people's lives. The Way Kuripan River is a river that passes through several villages in the city of Bandar Lampung, which often overflows into community settlements if the rainy season arrives, especially in the Pesawahan, Kuripan and Karang Cities which are downstream from the river. Therefore, it is necessary to have an analysis to find out the river water level that passes through an area if the rainy season arrives whether or not it can be accommodated by the river body or not. Based on the survey in the field, it is known that the width of the Way Kuripan River is found in the Betung Hills, West Tanjung Karang District, which is 20 m and the depth of the river is 4.51 m. if the rainy season arrives, the upper reaches of the Way Kuripan River have a water level that is 0.5 m - 3.0793 m so that the depth of the river is still able to be accommodated by different river bodies with downstream rivers in Pesawahan and Karang Cities where due to sedimentation the depth of the river is only 2.78 m and the width of the river is 10 m, while during the rainy season the river water level reaches 0.5 - 5,216 m. so that the water that passes through is unable to be accommodated in the river body and overflows in the area.

Abstract

Lampung Selatan saat ini sedang menghadapi krisis air. Hal ini disebabkan maraknya perubahan penggunaan lahan menjadi pembangunan infrastruktur yang menyebabkan penurunan cadangan air tanah dan juga masalah banjir. Pemerintah daerah saat ini mulai membangun reservoir sebagai fasilitas penyimpanan air. Embung adalah teknologi konservasi di lokasi tadah hujan untuk mengatasi ketersediaan air. Embung Margodadi di Lampung Selatan dibangun untuk menyimpan air hujan, mempertahankan ketersediaan air tanah dan juga membantu siklus hidrologi. Selain itu peruntukan air embungnya untuk irigasi perkebunan warga. Banyaknya manfaat dan potensi embung, sehingga penelitian awal perlu dilakukan dalam analisis kualitas air. Untuk menganalisis kualitas air menggunakan indeks kualitas air berdasarkan parameter yang ditentukan, termasuk DO, BOD, total padatan, Nitrat, Fosfat, kekeruhan, pH, suhu, dan fecal coliform. Hasil yang didapat dari analisis kualitas air dengan indeks, air embung masih layak digunakan untuk kebutuhan masyarakat, karena hasilnya masih mengikuti standar kualitas kelas 3, yaitu untuk irigasi.
