Abstract

The ANN procedure was used to develop an explicit equation for predicting the water level profile in a gradually varied flow. The equation consists of a series of hyperbolic tangent functions, with the number of series being the same as the number on the node in the hidden layer. The ANN model consists of 3 layers: the input layer consists of four nodes, the hidden layer has seven nodes and one node in the output layer. The input parameters used are parameters related to distance, discharge, roughness, and depth of flow at the downstream end of the channel. The output parameter is the flow depth at various points. The model has been used to estimate the water level profile for different flow conditions. The comparison between the explicit ANN model and the numerical model results is satisfactory. The models can be extended to study more complex flows and non-prismatic channels. The model is promising as a tool in decision support.

Abstract

The construction of Musi V Bridge is part of the series of Kapal Betung Toll Road, with the toll road in and out of Social Street which is connected to Lettu Karim Kadir Street. This study aims to obtain the performance of roads and intersections in Gandus District, obtain transportation modeling of traffic movements due to KayuAgung-Palembang-Betung Toll Road interchange, obtain predictions of the performance of roads and intersections resulting from traffic simulation models and provide policy suggestions in the form of strategies and traffic engineering management techniques. Data processing used the 2014 PKJI method and simulation with Vissim program. Results of data processing show that the performance of roads and intersections in existing conditions is still able to accommodate traffic flow, indicated by the degree of saturation that meets 2014 PKJI requirements, namely (DJ ≤ 0.85) with service level C and Vissim simulation results show the largest delay and queue length located in segment 3 (M Amin Fauzi Street -Tph Sofyian Kenawas Street) which is 138.18 meters and 21.02 seconds and on Lettu Karim Kadir Street (Direction of Musi II) of 14.04 seconds and 58.96 meters. After the operation of the Musi V Bridge, there was an increase in traffic volume which resulted in decreased performance of roads and intersections. Therefore, to improve its performance, road widening is carried out. The results of 2014 PKJI analysis showed a decrease in the degree of saturation from 0.43 to 0.35, a delay from 9.02 seconds / cur to 8.22 seconds / cur and the chances of queuing from 8.50 - 20.39% to 6.04 - 15.91% on Lettu Karim Kadir Street (Musi II Direction).

Abstract

Flooding is a problem that is often found in cities, especially in the rural areas of Baturaja Permai. When it rains, the quantity of river water exceeds its capacity or becomes too much, and there will be inundation caused by overflowing rivers. Factors of natural events such as high rainfall intensity cause flooding, coupled with factors from human activities. This study aims to investigate flood characteristics by developing an integrated model between hydrology and hydraulics. The development of this flood model is based on the hydrological model of runoff using the synthetic unit hydrograph method Soil Conservation Service (SCS), a one-dimensional (1D) hydraulic model for water flow propagation in macro drainage systems, and two dimensions (2D) for calculations if the river flow exceeds the existing capacity so that it experiences water propagation in the inundation area using the HEC-RAS software. To model the flood inundation it is required data Digital Elevation Model (DEM) was obtained by measuring the height of the land using a Total Station (TS) measuring instrument and analyzed using ArcMap software. The calculation of direct runoff is designed for a 5-year return period. The simulation results indicate that the Baturaja Permai area is an area that is prone to flooding with inundation depth of 0.558 m - 4.692 m and a peak runoff discharge of 15.6 m³/s at a 5-year return period.

Abstract

Soil is an important element in supporting development activities in the world of civil construction. One type of soil that is often found in South Sumatra is clay. Clay soil is a type of fine-grained soil that is strongly influenced by water content. Each type of clay has a different carrying capacity value. Therefore, an analysis is needed to test the effect of adding a mixture of materials to the clay. A test was carried out to see the effect of adding mixed materials to the soil. In this test, soil samples were taken from the Banyuasin district and mixed with materials in the form of fiber, husk ash, and lime. For variations in soil mixture testing, 0.1% fiber, 2.5% husk ash, and lime consist of 2.5%, 5%, and 7.5%, as well as plain water. The test results show that the addition of a mixture of fiber, husk ash, and cement can improve the physical and mechanical properties of clay, where the optimum addition variation in the 4th variation is a mixture of soil + fiber 0.1% + husk ash 2.5% + lime 5%, which is 52.49%.

Abstract

In structures located in earthquake-prone parts, energy dissipation capacity is one of the criteria that must be achieved by the structure. For old structures or built long before earthquake regulations were introduced, it becomes very vulnerable to earthquakes, so it necessitates to be anticipated to prevent collapse, and one method that can be done is by jacketing. In this subject field, testing was conducted using a cyclic load on a reinforced concrete square column measuring 300 mm x 300 mm, which jacketing using wire mesh and self-compacting concrete. From the test results, it was found that in specimens jacketed with M6 wire mesh and self-compacting concrete experienced an increase in accumulative energy dissipation by 23.32% with a relatively minor loss of strength.

Abstract

The toll road network in Indonesia is growing very rapidly in line with the plan of the Government of the Republic of Indonesia to build 24 toll roads on the island of Sumatra which will connect every provincial capital. The impact of toll road construction is certainly different in each region, and those who feel the greatest impact in the areas closest to them. Toll roads, both existing and planned, cause the development of local roads in the vicinity directly or indirectly. Development of road network systems can affect the movement so that network performance becomes better and increasing road capacity is not the right solution to overcome congestion on the road. This study discusses the impact of the construction of the Trans Sumatra toll road on the national road network in the city of Palembang by using four-step models and a macro simulation program, namely the software PTV Visum. The model reliability test resulted in a determinant coefficient (R2) of 0.7227, which means it represents the existing traffic conditions in the field. The modeling stage is continued to predict the performance of the road network after the Trans Sumatra Toll Road operates. Prediction results show in 2036 there will be a decrease in the level of service with the increase in the V/C Ratio of National Roads that directly access the Trans Sumatra Toll Road. Adding more traffic lanes in 2031 and 2036 on these roads, will significantly improve the performance of the National Road network. The unification of the Trans Sumatra toll gate also helps to increase the level of service on the nearest road.

Abstract

Expansive soils have high compressibility, swelling, and shrinkage properties. So we need an effective method to improve soil conditions when the structure is built on it. This paper presents the results of research on the effect of the substitution of ceramic waste on the physical properties of the expansive soil. Soil improvement using construction waste will contribute to reducing the amount of waste and conserving natural resources. The stages of the research included testing the physical properties of both soil and waste materials, then testing the physical properties of the mixed soil which included the Atterberg limit test, soil compaction test, and SEM test. The addition of ceramic waste powder can function as a material that can chemically change the physical properties of the soil. There was a decrease in the optimum water content (wopt) of the soil and an increase in the maximum dry density (gd max) value of the soil along with the addition of the percentage of ceramic waste powder that was up to 1.410 gr/cm3. The percentage of chemical content (SiO2 and Al2O3) in ceramic powder affects soil compaction parameters and decreases soil plasticity index, where the content of SiO2 and Al2O3 in ceramic powder 1 is higher than ceramic powder 2 giving lower IP (Index Plasticity) values and optimum moisture content, respectively by 16.26 and 28%, and a higher maximum dry density value of 14.4 gr/cm3.

Abstract

Batutegi Reservoir is a multi-purpose reservoir that is used to increase the water supply to the Argoguruh Weir to expand the irrigation area in the Sekampung Irrigation System. Batutegi Reservoir supplies the water demand not only for irrigation, covering an area of 66.573 Ha, but also for hydroelectric power generation (hydropower) of 2 x 14 MW and the raw water supply of 2.250lt/s. The operational curves of the Batutegi Reservoir were prepared in 2017, aiming to control the water release to ensure the planned demand is fulfilled. However, the reservoir operation curves must be reviewed at least once every 5 (five) years to comply with the changes in reservoir conditions and the development of its benefits/functions. The study aimed to determine the reservoir reliability by updating the reservoir operation curves in 3 conditions; wet year, normal year, and dry year using the SOR (Standart Operating Release) simulation method according to the inflow and outflow during the mid-month period. Results showed that in the wet year, normal year, and dry year, the reservoir reliability in supplying water for irrigation, raw water, and hydropower is satisfactory in each period. In conclusion, although some simulation periods showed the final RSL (Reservoir Water Levels) of the reservoir are below the upper limit of the operation curves, they are still above MOL (Minimum Operation Level) hydropower level meaning all supply for irrigation, raw water, and hydropower can be 100% fulfilled.

Abstract

Permeable pavement is a type of road pavement that allows stormwater to infiltrate through the pavement surface and the underlying base layer to reduce surface runoff. Open-graded aggregates are often used as the base layers to temporarily store water and allow the water to infiltrate slowly into the soil below the pavement or through sub-drainage. The strength of open graded material is usually less than the dense-graded materials. Therefore; the mixture of the aggregate for both base and drainage layer need to be designed carefully. In Indonesia, the criteria for aggregate as both base and drainage layer is stipulated in Bina Marga Specification. This study aims at designing an optimum mixture of local aggregate to be used as the base of permeable pavement. The mixture should fulfil the mechanical properties based on laboratory CBR value, and hydraulic properties based on storage capacity and the coefficient of permeability. Five aggregate samples of Andesite origin from South Lampung area were selected for this study. Careful laboratory test procedures were adopted to select configurations of aggregate sizes (design mix formula) that satisfies the requirements both as Aggregate A and as drainage layer. A dense graded aggregate based on the grain size distribution was prepared for design mix formula to meet the requirement as Aggregate A. Then, the fine particles passing No 40 sieve was removed to form open aggregate sample suitable as drainage layer. Both samples were tested for grain size distribution, CBR, permeability and storage capacity. Results show that the local aggregate fulfils the requirements both as base and as drainage layer with average CBR of 92%, average storage capacity of 18.32% and average permeability of 0.05 m/sec. The thickness of the permeable pavement layer could be estimated based on storage capacity and the permeability of the drainage layer.

Abstract

Roads must have the appropriate mix of thickness and design to protect the subgrade from damage and to accommodate the load pressure on the road. The purpose of this research is to investigate the effects of adding crumb rubber to the hot asphalt mixture of the Laston AC-WC type. The research was conducted in two stages, involving the creation of test specimens. In the first stage, the bitumen content of the specimens included 5%, 5.5%, 6%, 6.5%, and 7%. In the second stage, In the second stage, crumb rubber was added to the mixture at percentages: 0%, 5%, 10%, 15%, and 20%. The crumb rubber was mixed using the dry mix method. Several parameters were considered based on the results of the Marshall Test, in accordance with the General Highways specifications (VFA, VIM, VMA, Stability, Meltability and MQ). characteristics analysis aims to determine the impact of crumb rubber content on the elasticity, durability, and other properties of the asphalt mixture. Of all the variations of the hot mix asphalt type Laston AC-WC mixed with crumb rubber; the optimum level of crumb rubber mixture was obtained at 5% for the hot mix asphalt type Laston AC-WC. From the research results, when 5% crumb rubber was added to the asphalt mixture, the following values were obtained: 856.1 kg stability, 3.07 mm flow and 290.40 kg/mm MQ. In contrast, the stability value of hot asphalt concrete asphalt concrete type AC-WC with 5% asphalt has 813.7 kg stability, 3.03 mm flow and 268.30 kg/mm MQ.
