Abstract

The impact that occurs from the rampant development of residential areas will certainly make the volume of surface water flow or run off become large. Drainage is a system created to deal with the problem of excess water flow that is above the surface of the earth, some of the things that cause excess water are caused by high water intensity and the long duration of rain. In this study, the problem that occurred was in the drainage network in the residential area of Vila Rizki Ilhami 2 Sawangan, which was a transfer of land functions from infiltration land into a residential area. Evaluation that must be done is covering hydrological analysis and hydraulics analysis to get the amount of flood discharge plan that will be used to analyze the capacity of the planned channel so that no flooding occurs at the location of the settlement area when the settlement is built, recommendations for drainage system design and determine the size of the river dimension / size / times that should be made when accommodating water discharge during maximum rain so that the flood control system can be well integrated. With 3 methods of calculating rainfall, the method of calculation is selected using the gumbel method which is SNI (Indonesian National Standard) with a return period of 2 years, 5 years and 10 years. From the evaluation obtained is to add height height or free board to accommodate flood discharge plan.

Abstract

Drainage is a way to dispose of excess water that is not in an area. In other words, this drainage also works in controlling checked areas, puddles, and also flooding. Flooding is an event when excessive water flows overland. North Jakarta is an example of the city area in Indonesia that often experiences such flooding events with a repeated frequency every year. With low topographic conditions and also located in the northern coastal area of Java Island, resulting in a large flow of water through North Jakarta. One of the areas that always experiences flooding is Jalan Gaya Motor, Sungai Bambu Village Tanjung Priok sub-district. Flooding in this area caused major losses in economic mobility in North Jakarta because the road is the main access to an s considerable automotive factory area in the Jakarta area. Drainage systems in the area need to be designed to accommodate water discharge especially when it is raining. Drainage capacity needs to be accounted for to accommodate existing water discharge. From the results of the analysis obtained the amount of channel capacity value of 0.46 m3/s, then bulk discharge flood plan in the period of-2 Years 22.95 m3/s, for 5 Years 34.26 m3/s, for 10 Years 41.75 m3/s. With the flooded value of the plan, it was concluded that the capacity of the existing channel could not accommodate rain at the peak discharge of the plan, so the area always experienced flood events. Also, drainage channels in the area were affected by the high rise in water levels due to the influence of tides with an average increase of 0.6 m with an average elevation of water level of 0.607.

Abstract

One of the goals of development is to improve the welfare of the community by building various supporting facilities and assets in people's lives. Depok City plans to build the Sawangan 1 State Elementary School. Environmental impact analysis studies are needed to predict the environmental impacts that will occur. This research aims to analysis the environmental baseline quality and predict the impacts that will occur as well as how to minimize impacts at the pre-construction stage, construction stage and operation stage. This research using observation method, interview method, and scoping. The results of this study are the initial environmental baseline at the research site indicates that the environmental quality at the research site is in good category, both in terms of ambient air quality, air quality and air quality, in order to create an environmental concept development environment. The predicted impacts that arise in the reconstruction activities of the Sawangan 1 State Elementary School, Depok City are at the pre-construction stage the impact is in the form of public perception, at the construction stage in the form of a decrease in air quality, an increase in increase, an increase in surface runoff, job opportunities and business opportunities, public health problems, domestic waste generation as well as the emergence of positive and negative public perceptions of construction activities, while at the operational stage the predicted impacts will be a decrease in air quality, increased opportunities and job opportunities for the surrounding community, public health problems, changes in environmental sanitation, traffic disturbance traffic and the emergence of public perception. In general, to minimize the negative impacts that occur in any reconstruction activity of the Sawangan 1 Elementary School building, Depok City can be carried out by means of a social approach with the community, carrying out construction activities only during the day, prioritizing local communities as workers, during the construction phase until the construction phase. and as a provider of workers' needs, optimizing reforestation in the environment and greem opem spaces as well as good waste management and complete cleaning facilities so as not to interfere with public health and produce environmentally friendly development.
