Abstract

The Martapura River Bridge is located on Jalan A. Yani KM 40 Martapura, Banjar Regency, South Kalimantan. Traffic processes that occur on Jalan A. Yani KM 40 Martapura often experience problems because congestion often occurs and the condition of the old IA bridge sometimes makes driving users feel restless when crossing the bridge located on the Martapura river. So that at the location of the Martapura river, it is deemed necessary to build a bridge next to the IA bridge so that the IB bridge to be built can be more sturdy and durable so that there is no anxiety for driving users and also to reduce congestion that occurs, where later the IB bridge will be used as a road with one way only towards Banjarmasin and the martapura IA bridge will be used as a one-way road towards the Hulu Sungai so that it will make it easier for traffic on Jalan A. Yani KM 40 Martapura. The methodology used in loading planning refers to SNI 1725-2016 concerning Loading Standards for Bridges. For the methodology in calculating the stress loss, refer to the NAASRA Bridge Design Specification on Chapter VI Bridge Design Specifications (Prestressed Concrete Design). For the methodology in calculating the moment of the vehicle floor using the Three Moment Equation method and for the method of subsidence of group pile foundations using the method of Schultze and Sheriff (1973), assuming that the pile group is the Equivalent Raft Foundation. The material used in the design of the upper structure is prestressed concrete, while the lower structure is planned to use reinforced concrete with a square pile. The results obtained are the T-Girder Prestressed type bridge with class A, 34 m span, 7 m traffic width, and 1 m wide sidewalk. Prestressed T-Girder is designed using fc' 40 MPa (K-482) Strands used are uncoated 7 wire super strands ASTM A-416 grade 270 with a diameter of 12.7 mm and an area of 100 mm2 with a tensile strength of 1860 MPa. As for the lower structure, the abutment uses concrete with a quality of fc' 25 MPa (K-300) with a height of 565 cm, a width of 480 cm and a length of 1050 cm.type piles Square Pile with a length of 15 m with a quality of 50 MPa (K-600) with a width of 60x60 cm with a configuration of 18 piles for each abutment. Estimated Budget Plan The cost of constructing the Martapura river bridge is IDR 8,129.511,475.00.-.

Abstract

The characteristics of rainfall in Banjar Regency can be known by analyzing the rainfall data that occurred in Banjar Regency. To conduct rainfall analysis, the data was obtained from the Banjar Regency Central Bureau of Statistics, which is contained in the Banjar Regency in Figures from 2014 to 2023. The data that used in this analysis is maximum rainfall data. The research method that used in this analysis is frequency analysis to determine the suitable distribution method to be used based on the available data. Based on the analysis, it was found that the distribution method that meets the requirements for analyzing design rainfall is the Log Person III method. The design rainfall for a 2-year return period is 456.6607 mm, for a 5-year return period is 603.5907 mm, for a 10-year return period is 713.0071 mm, for a 25-year return period is 1178.534 mm, for a 50-year return period is 990.5573 mm, and for a 100-year return period is 1125.165 mm. Using the Monobe method, an analysis is conducted to determine the rainfall intensity for each return period. The highest rainfall intensity is estimated to occur at the 25-year return period, which is 408.575 mm. It is expected that this research can help the local government and the community to be considered as a basis for flood control building planning in Banjar Regency

Abstract

This research intends to determine whether the capacity of existing drainage channels is still sufficient or not. The method of analysis used involved collecting rainfall data over the past 14 years (2010-2023) from the Class I Banjarbaru Climatology Station and obtaining the dimensions of the drainage channels from direct field measurements. From the results of the study, it was found that some of the drainage was unable to withstand the discharge plan, so redesign and new drainage design were needed. The planned channel dimensions for the redesigned drainage have a channel depth of 1 m and a planned width of 0.9 m. The planned channel dimensions for the new drainage have a channel depth of 0.9 m and a planned width of 0.7 m.

Abstract

The Guntung Payung River in Banjarbaru City has undergone a structural cross-section modification from a box culvert to a bridge to address flooding caused by the inability of the existing cross-section to accommodate peak rainfall discharge. This study employed a Steady Flow 1D hydraulic simulation using HEC-RAS version 6.5 to analyze the impact of structural cross-section changes on water surface elevation and flood inundation area. The data used included river cross-section measurements, maximum daily rainfall over the past 20 years, and a Digital Elevation Model (DEM) map. The design discharge was calculated using the Rational Method for return periods of 2, 5, 10, 20, and 25 years. The results indicated that, for a 25-year return period, the water surface elevation at the downstream section (STA 0+190.75) decreased from 5.05 m to 3.75 m, and the inundation area was reduced by 61.15%. Conversely, the upstream section (STA 0+3116) showed no significant changes in water surface elevation or inundation area. These results indicate that the cross-section structure change is more effective in reducing flood potential downstream but does not impact the upstream area. Keywords: Guntung Payung River, HEC-RAS, Steady Flow 1D, cross-section structure change, water surface elevation, inundation area.

Abstract

To increase rice production in Tanah Laut Regency, one of the programs implemented by the Tanah Laut Regency Government is the development of swamp irrigation areas in Sabuhur Village. Sabuhur Village has a large swamp area, which has great potential to be developed as agricultural land. However, the success of this development is highly dependent on the suitability of the soil for use as agricultural land. Therefore, testing the physical and chemical characteristics of the soil is a crucial first step to identify the potential and constraints that may occur. The method used is field sampling and laboratory testing. Based on the test results, it can be seen that the characteristics of the physical and chemical properties of the soil at the research location. In terms of soil physical properties at the location, it can be known that soil permeability ranges from 1.86-3.64 cm/h (silty clay), bulk density ranges from 1.01-1.46 g/cm3 (most have exceeded critical values for agriculture), particle density ranges from 1.9-2.86 g/cm3 (mineral soil conditions), porosity ranges from 38.83%-63.31% (silty clay), and aggregate stability ranges from 14%-62.8%. As for the chemical properties of the soil, the total Fe content ranges between 112.19-507.47 ppm, pyrite content between 0.004-0.053% (small pyrite content), CEC ranges between 16.15-30.81 me/100gr (moderate to high soil clay content), and moisture content ranges between 4.88%-29.03. Therefore, the sampling location is not a swamp area because it is mostly mineral soil with a small moisture content. The observation location is a permanently submerged wetland environment.
