Abstract

Water is the source of life and take on an important role in supporting human activities. Form of the problems faced in the utilization of water resources management in general is a problem right way so that at the optimum can result from existing resources. Efforts should be made to overcome these problems by taking into account the constraints faced, the negative impacts and completion is expected to be effective and efficient.Among the various alternatives, the research to optimize the utilization of the water dam Batutegi an option. Linear program is one form of optimization techniques. The objective function is to maximize the amount of water that can be supplied for irrigation. The problem is the availability of water in the dam Batutegi. Completion of this optimization problem using QM For Windows software.Efficiency optimization results are outflows of 2:05 m3/sec in the first growing season, 1:19 m3/sec in the second growing season and the addition of irrigated area of 1,100 ha in the first growing season, 512 ha in the second growing season.

Abstract

Synthetic unit hydrograph is a synthetic based hydrograph of watershed parameters. One way to find out the magnitude of the flood watershed of Way Tebu River Basin is to predict the amount of flow from existing rain data, Therefore rainfall data as the main input of rain diversion process becomes a very important thing and must have a high level of accuracy. The research presents a simple approach to determine peak discharge and unit hydrograph form in the Waytebu River Basin. Several methods of unit synthesis hydrograph such as Nakayasu, Limantara and Snyder are used to calculate peak discharge and hydrograph form. Flood discharge plans with various reworks in each method, providing mixed results. The greatest result is the Limantara HSS (Q25 = 1,413.13 m3 / sec) and the smallest HSS Snyder (Q25:814,57 m3 / s), while HSS Nakayasu (Q25 = 922.93 m3 / s). From the hydrograph comparative analysis of the three methods for Limantara method, the top time is happened at (Tp: 5.57) with top flow (Qp: 10,19 m3 / s), While Nakayasu method has the same top time at (Tp: 5,93 ) with top flow (Qp: 11.65 m3 / s) and Snyder method top time happened ad (Tc: 5.57) with top flow (Qp: 10.19 m3 / s)

Abstract

Kota Karang Village and Kota Karang Raya Village are two urban villages located in the coastal city of Bandar Lampung and are vulnerable to tsunami threats. The tsunami threat comes from the possible subduction of the Indo Australia Plate and the Eurasian Plate as well as the volcanic activity of Mount Anak Krakatau. The two villages are inhabited by 16.726 people with a high density of 29.344 people per km2 and occupy an area of 0,57 km2 with an average height of 10 meters. The dense population and moderate contours left both villages potentially causing casualties in the event of a tsunami disaster. Therefore, a study on the optimization of the tsunami evacuation route in both urban villages is needed. The method used in this research is to conduct a review of the tsunami evacuation route through analysis of population data and topographic data which will then become evacuation simulation input using Evacuware software. The data included in the form of population data by sex and age and topographic data in the form of situation map and evacuation route map. The simulation is done with two scenarios, the first scenario uses two Temporary Evacuation Sites namely Mount Mastur and Dwipangga Park. The second scenario conducted by placing four additional vertical shelter using three reconstructed primary schools and one reconstructed community health center

Abstract

Way Semah River is the longest river located in Pesawaran Regency. Way Semah Creek passes several villages such as Gedong Tataan, Kesugihan, Kagungan Ratu, Katon Country, Halangan Ratu, Negara Saka, and many other villages. The upstream area of the Way Way River is located on Mount Pesawaran, while the downstream of the Way Semah River goes to the river Way Sekampung. The purpose of this study is to find out the fluctuation picture of the rising and falling water flow in the Way Semah river, knowing the peak discharge and the length of flow time, in certain period. The purpose of this study is to analyze rainfall occurring in das way semah. know the fluctuation of the water flow with the hydrograph of nakayasu, Limantara, and Snyder methods, and comparH Limantara, strongly influenced by the slope of the river, the higher the elevation difference between the upstream and downstream of the river, the higher the Qp value, and the reverse is true, whereas for the Tp value is relatively the same

Abstract

DAS Way Sulan located in East Lampung Regency of Lampung Province. DAS Way Sulan this was the area of review in the research of the preparation of this thesis. Flood-prone areas in the planning area includes the  rea of the estuary's Way Home, flood plains and alluvial plain especially along the Way Sulan. Factors cause flooding include the high rainfall, the closure of land upstream capacity and reduced flow of the rivers especially in areas of lower reduced due to sedimentation and topographic area. Flood hazards/safeguards for potential flooding in River Way Sulan can do planning safeguards against a flood with a building plan that aims to reduce the damage that occurs due to the flood levels most minimum. Building planning in the field of water resources can be done well if rainfall data at each station the rain can be known and calculated using the debitnya method of the HSS

Abstract

Ketibung catchement area administratively located at Southern Lampung and Eastern Lampung districts. Ketibung river upstream is Ketibung dam that administratively located at Talang Baru village Sidomulyo districts Eastern Lampung district. Ketibung river has a variatif wide from upstream to downstream, river’s wides at the upstream approximately ± 8,5 m, wides at the middle stream approximately ± 6,8 m and at the downstream approximately ± 7,2 m, with the catchement area extensive approximately 315 km2. At these areas hidrology data are not avaliable, to decrease unit hidrograf, synthetic hidrograf unit is made according to physical characteristic of Ketibung catchement area. Using HSS Nakayasu, Limantara and Snyder methods that will be used as flow at river infrastructures planning for the flood management. From these three methods, for the biggest design flood is using Snyder method (Q25 : 653,72 m³/second), for Limantara Method (Q25:416,45 m³/second) and Nakayasu ( Q25 : 519,40 m³/second). For HSS Limantara, the top time is happened at (TP:4,91) with top flow (Qp:7,813 m³/second), while HSS Nakayasu has the same top time at (TP:4,91) with top flow (Qp:11,5 m³/second) and HSS Snyder top time happened at (Tp;5,39) with top flow (Qp:10,80 m³/second)

Abstract

Hydrological data is not available in most areas of Lampung Province. To decrease the unit hydrograph, then it’s made a Synthetic Unit Hydrograph is created based on the physical characteristics of the River Basin. Way Kandis River which is a creek of Way Sekampung River is one of the watershed that does not have unit hydrograph so it is necessary to make HSS calculation from some existing method. The design flood debits calculated in this study were Q2, Q5, Q10, Q20, Q25, Q50, and Q100 using the HSS Snyder Method, the Nakowsasu HSS Method and the Limantara HSS Method. The peak debit (Qp) results on the highest 100 year (Q100) recalculation on the Limantara Q100 method = 615.44 m3 / sec HSS by a margin of less than 5 m3 / s through the Snyder Q100 method = 610.79 m3 / s. Lowest Method Nakayasu Q100: 437,40 m3 / s. The time to reach the longest peak (Tp) discharge on the Snyder method = 8 hours by 1 hour difference in each method. Nakayasu Method = 7 hours and Limantara Method = 6 hours. Of the three methods HSS can not yet predicted which approach approaches the flood hydrograph in Way Kandis watershed because there is no data for calibration. Therefore, further research is needed to obtain measurable flow data on Way Kandis River
