Abstract

Hujan adalah bagian dari siklus hidrologi yang paling berbahaya karena dapat menyebabkan erosi. Penelitian di Kebun Kolektif TP PKK Kota Bandar Lampung mengindikasikan kekurangan unsur hara akibat erosi yang disebabkan oleh limpasan air hujan, ditambah dengan kondisi lahan yang cukup curam. Tujuan penelitian adalah menganalisis pengaruh variasi kemiringan dan intensitas curah hujan terhadap laju erosi serta upaya pengendaliannya. Metode yang digunakan pada penelitian ini adalah rainfall simulator. Hasil dari penelitian adalah laju erosi terkecil terjadi pada intensitas curah hujan 0,75 liter/menit dan kemiringan lereng 8% terjadi sebesar 0,04 Ton/Ha sedangkan laju erosi paling besar terjadi yaitu pada intensitas curah hujan 1,75 liter/menit dan kemiringan lereng 45% terjadi sebesar 0,59 Ton/Ha, terlihat bahwa intensitas curah hujan dan kemiringan lereng mempunyai pengaruh signifikan terhadap laju erosi tanah, laju erosi semakin meningkat seiring dengan kedua faktor tersebut. Kesimpulannya adalah curah hujan dengan intensitas tinggi dan kemiringan lereng yang curam meningkatkan laju erosi yang dapat merusak struktur tanah, sehingga perlu dilakukan teknik konservasi untuk mengurangi laju erosi dan menjaga kesuburan tanah, seperti pemeliharaan vegetasi penutup tanah dan penyuluhan teknik konservasi tanah bagi petani dan masyarakat.

Abstract

The calculation is done using the rainfall data obtained from BMKG Kotabumi North Lampung,from 1998 until 2011 with time increment in minutes. The Log Pearson III method is used to findthe design rainfall with return period 2 years, 5 years and 10 years. Then the result isimplemented in the Intensity-duration-frequency (IDF) curves. Time of concentration is linked intothe IDF curves to determine rainfall intensity. Based on the calculated rainfall intensity, thedesign discharge for each return period can be calculated using the rational method.The values of design discharge are then inputted as upstream boundary condition in HEC-RAS.Model output are presented in cross and long section to determine at which return period thedrainage capacity is overflowed. Simulation using HEC-RAS were also done to determine thechannel capacity.Based on the results of this research, it can be concluded that rainfall intensities are 52,6918mm/hour, 65,7820 mm/hour and 75,9032 mm/hour, for 2, 5, an 10 year return period respectively.The capacity of the drainage channel is 2.02 m 3 /hour and is expected to be exceeded on 5 yearsreturn period.Key words : Intensity, Rasioanal method, HEC-RAS, capacity

Abstract

          Water is the source for life. Earth is called the blue planet, as water covers three-quarters of Earth's surface. It's just that most of the sea water (salt water).  Generally, the condition springs in Indonesia experienced a decline in the amount and debit, were damaged in the catchment area and the surrounding environment. To determine the existence of water resources, necessary to identify water resources. This research is to identify the sources of springs in knowing the status of water resources.          The primary data collection is done by identifying the condition of land cover in the catchment area, the condition of the springs, the condition of land cover in a radius of 200 m, the performance of the fountain, the critical level of water catchment areas, the critical level of water catchment areas, the critical level of a radius of 200 m, utilization springs, and the dependence of communities on water resources. While the collection of secondary data obtained from BPLHD Kab. East Lampung in the form of water quality data from 12 springs. Spring Water Quality Analysis using WQI Malaysia with graphic works of Dr. GatotEkoSusilo, S.T., M.Sc.          From the calculations, the average value of the 12 WQI water source is 95.1, meaning that all 12 springs are so richly used by people for drinking, bathing, cooking and others. The 12 water spring in the district of Batang Among them there are 5 springs, in the district of Marga Tiga there are 5 springs, in the District of Sri Bawono there is one source of water, and in District Jabung there is one source of water. Keywords: Water, Water Quality, East Lampung Spring Water, Water            Quality Index Malaysia
