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.</p> Muhammad Cahyono Copyright (c) 2022 Muhammad Cahyono 2022-06-07 2022-06-07 11 1 1 6 10.35139/cantilever.v11i1.131 Stabilitas Pilar Beton Pracetak Segmental Pada Jembatan Standar Terhadap Beban Dinamik <p>The use of precast technology in the manufacture of segmental components for the bridge substructure is one application that can be used in the acceleration of bridge construction. Better concrete quality and precision are two advantages that can make precast technology a solution in accelerating bridge construction. Commonly, segmental precast concrete piers are not designed to resist earthquake loads; however, the use of segmental piers systems is still possible in seismic zones by limiting additional dead loads. This study discusses the load limitation using the dynamic response calculation methodology of segmental precast concrete pillar structures to the El Centro (1940) earthquake load by varying the slenderness of the piers/column between 22 to 100. Examination of the stress combination due to axial load (DL) and inertia load due to the earthquake is carried out to find out how much residual stress can be accommodated by the piers/columns. Additional dead load (W<sub>ADD</sub>) is obtained by using Newton's second law by dividing the allowable additional inertial load based on the residual stress to the peak ground acceleration. The calculation results show a good correlation between piers’/columns’ slenderness and the proportion of additional dead load (W<sub>ADD</sub>) to dead load (W<sub>DL</sub>), so that the applicability of using segmental precast concrete piers/columns in seismic zones can be predicted earlier through this correlation.</p> Anton Husen Purboyo Hinawan Teguh Santoso Copyright (c) 2022 Anton Husen Purboyo, Hinawan Teguh Santoso 2022-06-08 2022-06-08 11 1 7 16 10.35139/cantilever.v11i1.130 Identifikasi Penyebab Kecelakaan Kerja Konstruksi Menggunakan Accident Root Cause Tracing Model (ARCTM) dan Fault Tree Analysis (FTA) <p>The construction sector greatly contributed to the increase in the number of injuries and even deaths of workers. This study aims to identify unsafe conditions and unsafe acts and to analyze the causes of work accidents on the Talago Embung Project in the village of Sikabu kabu, Luhak, District of Limo Puluh Kota by using the Accident Root Cause Tracing Model (ARCTM) and Fault Tree Analysis (FTA). Data were collected through observation, in-depth interviews, and documentation. The causes of construction accidents identified are as follows; a) environmental factors i.e. weather or climate, lack of lighting, b) tools and facilities factors i.e. equipment life cycle, availability of Personnel Protective Equipment (PPE), and negligence in maintaining it, c) human factors i.e. personal issues, work pressure, and physical condition of workers, lack of skills and experience of workers, and d) management factors i.e. ineffective communication between the management team and workers and among workers, inadequate SOP and inappropriate material layout planning. Based on the results, it is expected that there will be training directly related to tasks and work safety, adequate project layout planning, proper supervision, and adequate maintenance of work safety equipment.</p> Utami Dewi Arman Jihan Melasari Aldan Roby Suwanda Copyright (c) 2022 Utami Dewi Arman, Jihan Melasari, Aldan Roby Suwanda 2022-07-08 2022-07-08 11 1 17 28 10.35139/cantilever.v11i1.112 Analisis Tingkat Layanan Ruas Jalan dan Persimpangan di Kecamatan Gandus Akibat Pembangunan Jalan Tol Kayu Agung – Palembang - Betung <p>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&nbsp; 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).&nbsp;</p> Melawaty Agustien Debby Yulinar Copyright (c) 2022 Melawaty Agustien, Debby Yulinar 2022-07-11 2022-07-11 11 1 29 38 10.35139/cantilever.v11i1.56 Analisis 1D – 2D Genangan Banjir pada Kawasan Perumahan Baturaja Permai, Kecamatan Baturaja Timur <p>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.</p> Rudy Suryadi Dinar Dwi Anugerah Putranto Imroatul C.

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%.</p> Indrayani Indrayani Andi Herius Puryanto Puryanto Revias Noerdin Maharu Ismail Siti Aisyah Copyright (c) 2022 Indrayani Indrayani, Andi Herius, Puryanto Puryanto, Revias Noerdin, Maharu Ismail, Siti Aisyah 2022-09-14 2022-09-14 11 1 49 54 10.35139/cantilever.v11i1.132 Disipasi Energi Pada Kolom Dijacketing Dengan Wire Mesh dan Self Compacting Concrete Akibat Beban Siklik <p>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.</p> Hence Michael Wuaten Copyright (c) 2022 Hence Michael Wuaten 2022-08-01 2022-08-01 11 1 55 64 10.35139/cantilever.v11i1.136 The Impact of Trans Sumatera Toll Road Development on The National Road in Palembang City <p>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 (R<sup>2</sup>) 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.</p> Perwira Manggala Wicaksana Erika Buchari Melawaty Agustien Copyright (c) 2022 Perwira Manggala Wicaksana, Erika Buchari, Melawaty Agustien 2022-09-14 2022-09-14 11 1 65 72 10.35139/cantilever.v11i1.137
