Flood is a disaster caused by various factors. Floods have caused many losses, ranging from disruption to daily activities to the loss of a person's life. Kelapa Gading is an area that is often hit by floods. This indicates that there are many factors that can cause flooding in Kelapa Gading. This study aims to find the factors that cause Kelapa Gading to be frequently flooded and solutions to reduce flooding in the area. There are several factors that needs to be examined, rainfall, drainage capacity, and drainage conditions. Drainage capacity will be calculated using the Manning method to determine the discharge from the existing drainage channel. Then it will be compared with the discharge caused by rainfall. From the results of the analysis, it is known that 12 of the 32 channels reviewed are not able to accommodate runoff discharge. After the analysis, it can be concluded that the factors that cause flooding are from the capacity of the drainage channels and external factors such as the presence of sediment at the bottom of the channel or the channel is obstructed by road construction. The solutions to this problem, deepening drainage channels or making infiltration wells in flood-prone areas. ABSTRAKBanjir adalah sebuah bencana yang disebabkan oleh berbagai faktor-faktor.

Abstract Road drainage function as important part that can control a large rainfall that caused puddles that often disturb the comfort of all community activities on the road. Condition of the drainage channel on the road Kebon Pala area, East Jakarta are not qualified due to mistake planning and lack of maintenance. Hence, it is necessary to evaluate the capacity of drainage channel on Road Perindustrian. The purpose of this study is to find the maximum amount of water flow that can be accommodated by drainage channels. Rain intensity was calculated using the Mononobe method, as well as the flow rate is calculated using the Rational method. The existing capacity of drainage dimensions are measured directly in the the field using Manning method for calculating flow velocity. The results obtain Q2yrs = 1.27mm/s, Q5yrs = 1.67mm/s, Q10yrs = 1.84mm/s, while Q channel 0.24mm/s. Thus, it can be concluded that capacity of road drainage channel is lower than Q rain that can not accommodate the existing rain flow.

Drainage Capacity

Changes in land use, namely from cultivated land to closed land or settlements, make the water demand in the area increase, if the water that comes out is not balanced with the water that enters the ground, it will cause a decrease in the ground water level. Another problem that arises due to changes in land use is runoff, where runoff occurs due to rainfall exceeding the suction power or infiltration of the soil, so that over time the runoff becomes a puddle and can even cause flooding. One way to overcome these problems is to apply infiltration wells. This case study takes place in the Hang Tuah Cipta Residence Housing Area, Pekanbaru. From the results of field research and Hydrological data analysis revealed that the main existing drainage channel discharge with a discharge capacity of 0.923 m³/s is unable to accommodate the discharge that occurs at 1.19 m³/s. Segment or secondary drainage channels Q12 and Q13 are also unable to accommodate the discharge that occurs at 0.085 m³/s with a capacity of 0.06 m³/s. Based on the analysis results it is planned that the infiltration well with a radius of 0.5 m and a depth of 9 m which has a capacity of 0.0022 m³/s. After the planned discharge infiltration well comes out to be 0.88 m³/s, it means that the discharge does not exceed drainage capacity of 0.923m³/s.

Based on the geographical location of Pekanbaru City is one of the areas included in flood-prone areas, even said that the city of Pekanbaru is included in the red zone related to flooding, seeing from the majority of the existing area is the rawah and river banks. The National Flood Mitigation Agency (BNPB) noted that the city of Pekanbaru is one of the flood-prone cities on the island of Sumatra. In addition to determining flood-prone areas for the Regional BPBD Office in Pekanbaru City, the community also wants to know the location that often floods and determine the long-term rain intensity capacity that will cause flooding, so that it does not hinder the daily activities. To deal with this problem, a Geographical Information System needs to be developed that can determine areas that often occur in natural flooding. Geographical information systems are expected to be able to assist the BPBD Office in managing flood data that has occurred in the city of Pekanbaru, and help provide information about floods that are needed by the community to anticipate further flood events.

The siltation occurs nearly along the drainage channel at Sangga Buana II Street Palangka Raya. The catchment area for rainfall is increasingly dense with both residence and shop buildings so that the recharge area is also getting decreased. These factors are assumed able to cause a bigger flood. This study aims to evaluate the flood potential in the channel and design the dimensions of the channel required if the drainage discharge consists of design-discharge with a 2-year return period and domestic-wastewater discharge. This study is conducted in 2019 by using a survey approach. The flood potential is analyzed based on the comparison between both the drainage capacity and drainage discharge. The channel capacity is analyzed by the Manning method while the drainage discharge is analyzed by the Rational method. The domestic-wastewater discharge is assumed equally to 80% of the total use of clean water. The result of study showed that the channel capacity is smaller than the drainage discharge, and it occurs almost along the drainage channel of Sangga Buana II Street Palangka Raya. It means that the channel has flood potential so that it needs to be re-designed. The channel is designed with an opened-channel type and squared-shape with 0,65 m width and 0,65 m depth. The discharge direction is divided into two directions. The first direction flows to the drainage channel at Batu Suli Street while the second one flows to the drainage channel at Lawu Street. It is needed to build box culvert in the five locations to ensure that the discharge direction can flow to the drainage channel both at Batu Suli Street and Lawu Street.

Drainage Channels

A good road drainage system is needed to ensure that road user activities are not disrupted due to rain puddles. The cause of inundation that occurs is land use change, there is no drainage channel, the channel is not well connected, the channel is closed due to widening of the road without considering drainage channels. Given this, research needs to be carried out on the condition of the existing drainage system as a material consideration for evaluating its feasibility and planning a drainage system that is able to overcome the inundation that occurs. Writing this final project refers to primary data and secondary data that already exist. The rainfall data came from the Climatology and Geophysics Meteorological Agency, Balai Besar Region II, Bogor Regency, which is the Darmaga huajn rainfall measurement station and the PUPR Binamarga Office of Bogor Regency. Meanwhile, to find out the dimensions of the existing drainage channels obtained by conducting surveys and direct observation to the field. Data analysis which was carried out was hydrological and hydraulics analysis. Hydrological analysis includes the analysis of rainfall frequency, determining the repeat period, calculating the concentration time, analyzing the rainfall intensity, and calculating the flow flow plan. Based on the results of hydrological analyzes, the hydraulics analysis is then performed, such as calculating the plan channel profile and calculating the height of the planned channel guard. From all of these analyzes, the results of the drainage study on the Cigombong KM 16 - KM 23 highway were carried out, that is, the entire capacity of the existing canals was not able to accommodate the planned flow discharge for a return period of 2 years 5 years 50 years. In addition, the results of the analyzes that have been carried out show that the rain that occurs during a certain period of time and a certain return period greatly affects the planned drainage channel profile and is due to the large amount of garbage in the channel which affects the reservoirs in the drainage that often occur frequently

Life On Earth

Global warming and greenhouse gas emissions (GHGs) became a hot issue in the world today. An increased concentration of carbon in the atmosphere becomes one of the serious problems that can affect life on Earth. Peatlands pointed out as one of the sources of GHG emissions. Drainage of peatlands cause decreased water level so that the decomposition process is faster on a layer above the groundwater table, thus affecting the chemical characteristics of peat. In addition to affecting the ground water level, drainage also leads to a decrease in surface height peat soil (subsidence). Given the magnitude of the role of drainage and land use types in affecting carbon stocks and emissions of CO2 on peat soil, this study is to measure carbon stocks and emissions of CO2 on peat soil in forests and shrubs that have been drained. CO2 emissions increase with the closer spacing of the drainage channel that is at a distance of 50 m to 500 m of drainage channels. Meanwhile, at a distance of 5 m and 10 m of the drainage channel can not be concluded because of the condition of ground water that is stagnant at the time of sampling gas, so be very low CO2 emissions. CO2 emissions on the use of forest land are higher than the shrub land.
