Abstract

The river is a gathering place for water in the surrounding environment which flows towards a lower place. Way Besai river is located in Sumberjaya sub-district, West Lampung district which has an area of 410.72 km2. Direct runoff needs to be carried out on the Way Besai river to determine the flood hydrograph that occurs in the Way Besai river. The HEC-HMS model is a numerical hydrological model developed by the Hydrologic Engineering Center (HEC) of the US Army Corps Of Engineers.The methods used in direct flow runoff in the HEC-HMS software are the SCS UH method, the Clark's UH method and the Snyder's UH method. The purpose of this research was to analyze the Way Besai river flood hydrograph by calculating direct runoff using these three methods. The results of this study indicate that the SCS UH method is the most suitable compared to Clark's UH method and Snyder's UH method because it produces the smallest deviation value. Keywords : Way Besai, direct runoff flow, HEC-HMS, SCS UH, Clark's UH, Snyder's UH

Abstract

Water is all water that above or below the ground surface, including sea water that is on land. The need for clean water will increase, while clean water is scarce and must be paid handsomely. Meanwhile, the water source crisis is caused by the increasing need for water as a result of the growing population and land functions that can change the hydrological cycle. One way to meet human needs for clean water is by establishing the concept of rainwater harvesting, which is the concept of collecting rainwater that is stored in a reservoir and then the collected water can be used as an alternative source of water.The purpose of this study was to analyze the quality of rainwater before electrolysis and to determine the pH and TDS values of the permanent yield of rainwater and electrolysis.The results of this study are based on the results of laboratory tests showing that the overall quality of water in rainwater meets PerMenKes N0.416 of 1990. For the decreased pH and TDS values in the electrolysis process using a 1 ampere current adapter with a voltage of 300 volts has increased by 0 , 2-0.4 cm in acidic water. As well as for the area of titanium that affects the electrolysis process, the smaller the size of the titanium, the faster it will produce acid water.Keywords: water, rainwater, rainwater harvesting concept, electrolysis method, acid water.

Abstract

Spillway is a hydraulic structure whose existence is very important because it is built to release excess water or flood discharge that cannot be accommodated in the dam. The hydraulics analysis of this study used a spillway design (Stepped modified Spillway) with a 2-D physical model and the sediment used was sand with a uniform diameter of 1.8 mm or passed sieve no. 16. This research was carried out 5 times for every 25 minutes of upstream water level observations.In the Stepped spillway spillway the maximum scour (dsmax) occurs at an upstream height (H0) of 3 cm of 0.125 m with an Lds of 0.09 m from the downstream of the spillway. Meanwhile, for the Stepped Modified Spillway spillway, the maximum scour (dsmax) occurs at an upstream height ( H0) 3 cm is 0.076 m with Lds of 0.221 m. This shows that the greater the flow rate, the greater the depth of scour that occurs. So it can be concluded that the Lacey method is the closest to the laboratory results. This is because a balance has been achieved. The deeper the local scour that occurs, the more volume of sediment carried downstream of the weir.Keywords: Stepped and stepped modified spillway, local scour, sediment.

Abstract

The construction of a transverse structure on a river such as a dam and weir needs to pay attention to environmental factors and the surrounding ecosystem, especially for the ecosystem in the river. Therefore, it is necessary to build a fishway or fish in the transverse river structure so that the river ecosystem which has migration characteristics from upstream to downstream or vice versa is not disturbed because the migration route is blocked. This is the background of the author in taking the title of the thesis Analysis of the Effect of Slope and Basic Shape of Fishway on the Eel Movement Ratio (Anguilla bicolor, sp). The results of this study indicate that eels are nocturnal or active at night. Eel activity most often occurs at a fishway angle of 30 ° by testing using a 0.5 inch pvc pipe foothold type, while the lowest activity occurs at a 35 ° fishway tilt angle by testing using a 1 inch pvc pipe foothold type. The most effective slope based on the test results is at a slope angle of 30 ° but for a slope of 50 ° it can still be said to be effective because the activity ratio shows almost double the activity. Keywords: Fishway, Footing Type, Eel Activity
