  • Optimization of Resource Leveling Problem under Multiple Objective
           Criteria Using a Symbiotic Organisms Search

    • Authors: Doddy Prayogo, Christianto Tirta Kusuma
      Abstract: Scheduling and resource management are crucial in any construction project. Bad scheduling and resource management can cause delays or cost overruns. Optimization in solving resource leveling is necessary to avoid those problems. A total of nine objective criteria are used to solve resource leveling. Each of them has the same objective, which is to reduce the fluctuation of resource demand of the project. This study compares the performance of symbiotic organisms search (SOS) and particle swarm optimization (PSO) in solving resource leveling problems using separate objective functions. Those nine objective functions generate differing resource demand diagrams since each of them minimizes differing parameters. The results show that SOS produced a better solution in eight of the nine objective functions that are used, and only one objective function produced the same objective value in both SOS and PSO. Further finding reveals that one objective function is better in solving resource leveling than the others.

  • Strength Characteristics of PVC Coated Welded Wire Mesh as Steel Fiber
           Reinforced Concrete

    • Authors: Indradi Wijatmiko, Ari Wibowo, Christin Remayanti Nainggolan
      Abstract: Fiber concrete containing fibrous materials is manufactured to improve the low tensile strength of concrete and its brittle properties. In this research, fiber obtained from PVC coated welded wire mesh with diameter of 1 mm was utilized. There were several variations of fiber concrete samples made. Samples were subjected to tensile and compressive strength tests. The elastic modulus was measured by using extensometer and strain-stress gauges. The results show that the incorporation of PVC coated welded wire mesh increases the tensile strength of concrete, when the percentage of the fiber is 1.5%, with the length of 3.6cm, and the interlocking of 1.2cm. However, the compressive strength is slightly reduced from the normal ones. The elastic modulus results show that the introduction of PVC coated welded wire mesh tends to reduce the flexibility, as the value reduced 15-50% as compared to the normal ones without any fiber

  • Monitoring the Shear Fatigue Response of Reinforced Concrete Beams
           Subjected to Moving Loads using Digital Image Correlation

    • Authors: Benny Suryanto, George Staniforth
      Abstract: A series of three reinforced concrete beams without shear reinforcement were tested to failure under a centre-span monotonic load, a centre-span pulsating load, and a stepwise-moving pulsating load. During each experiment, load-deflection response was continuously monitored and at several stages during the experiment, the load was briefly stopped for crack observations. In addition to this manual crack mapping, more detailed crack mappings were undertaken using the digital image correlation (DIC) technique, employing the open-source DIC software Ncorr. It was shown that while the three beams exhibited a similar mode of failure (i.e. shear), each beam displayed a rather distinctive overall behaviour, particularly with regard to the load-deflection response and the nature of crack initiation and propagation. Results from the DIC analysis are presented to provide direct evidence on the damage progression during the load cycles and discuss the reduced fatigue life exhibited by the beam subjected to stepwise-moving pulsating load

  • The Correlation between Penetration Pressure Required to Install Pile
           Foundation and to Insert Bi-cones in Cone Penetration Test

    • Authors: Gogot Setyo Budi, Alvin Gilbert Tandiputra, Haven Kusuma Markho
      Abstract: One of the common methods used to install pile foundation is hydraulic jacked-in machine. In this method, a pile is pushed down into the ground up to the predetermined depth. The method has similar principle to that of Cone Penetration Test (CPT). This paper presents the correlation between the mobilize pressure required to install pile foundations and that required to push the bi-cones that attached at the tip of CPT rod. The results show that the penetration pressure required to install the pile into very soft clay layer is independent of pile diameter. The penetration pressure required to install the pile into soft to stiff clay layers depends on the pile diameter. The larger the diameter of piles, the smaller the penetration pressures required. The penetration pressure required to install the pile into stiff expansive clay layer beyond the depth of active zone can be predicted as high as the pressure calculated form CPT.

  • Impact of Earthquakes on the Transportation Infrastructure of Indonesia: A
           Preliminary Study

    • Authors: Anita Amirsardari, Massoud Sofi, Elisa Lumantarna, Iswandi Imran, Colin Duffield
      Abstract: Indonesia is a high seismic region and one of the most vulnerable countries prone to experiencing damaging earthquakes. It is critical that lifeline infrastructure remain operational or is quickly remediated after an earthquake to minimise physical, social, and economical losses. Not much work has been carried out in understanding the effect of earthquakes on transportation infrastructure systems. This study aims to gain a better understanding of the impact of earthquakes on the transportation infrastructure in Indonesia. This is achieved by firstly reviewing the frameworks and tools for conducting seismic risk assessment of lifeline infrastructure. The critical components of the transportation system are then identified. Various forms of transportation infrastructure damage caused by earthquakes are discussed. An overview of the damaging earthquakes for the past 20 years is presented. Finally, conclusions and recommendations are provided about the future work required for conducting risk assessment of the transportation infrastructure in Indonesia

  • Eco Drainage System for Surface Runoff Reduction in Indonesia

    • Authors: Cilcia Kusumastuti, Herry Pintardi Chandra, Kristanto Wibisono, Antonius Christopher Hartono
      Abstract: Sustainable urban drainage systems (SUDS) or eco-drainage system has been implemented in developed countries. The aims of the construction of the system are: to minimize surface runoff by capturing and temporarily retain it, to improve the quality of surface runoff, to infiltrate stormwater, to increase evapotranspiration, and to enhance landscape aesthetic value. Learning from the success of the implementation of SUDS in developed countries, the paper presents a model of eco-drainage system for residential area in Indonesia, which consists of rainwater harvesting system (RWHS) and retention ponds. A simulation of stormwater and surface runoff utilization is also presented. At 14,602.26 m2 bare land in Mojokerto Regency, East Java, which is transformed into residential area, the model of eco-drainage system could reduce surface runoff volume almost by 70%. It is recommended to adjust the dimension of rainwater storage tank and retention ponds in order to reduce more surface runoff volume.

  • Performance Evaluation of Hot Mixture Asphalt Using Concentrated Rubber
           Latex, Rubber Compound and Synthetic Polymer as Modifier

    • Authors: Nyoman Suaryana, Tedi Santo Sofyan
      Abstract: Research on the utilization of natural rubber for Hot Mixture Asphalt as modifier has been widely carried out, and more intensively since 2016 due to the declining global natural rubber price. Further research conducted is the utilization of pre-vulcanized concentrated rubber latex and rubber compound added with antioxidants and treated through vulcanization process. This study experimentally evaluates the performance of Asphalt Concrete Wearing Course (ACWC) using natural rubber and synthetic polymer as modifier, compared to ACWC without modifier (only petroleum asphalt).  The results show that the rubberized asphalt has higher index penetration value as well as higher elasticity compared to petroleum asphalt penetration grade 60, but lower than synthetic polymer modified asphalt. Similarly, the level of performance of rubberized asphalt mixtures, particularly resilient modulus, water resistance, deformation, and fatigue cracking, is between that of petroleum asphalt and synthetic polymer modified asphalt

  • Proposed Design Philosophy for Seismic-Resistant Buildings

    • Authors: Nanang Gunawan, Aylie Han, Buntara Sthenly Gan
      Abstract: Modern seismic design and technologies have undergone tremendous developments. In modern design codes, building structures subjected to high earthquake loads are allowed to experience plastic deformations without collapsing, and the design is permitted up to the ultimate strength. According to comparative results in Japan, the number of humans injured due to earthquakes is higher than the number of deaths/missing. Likewise, the number of residential buildings that collapsed are less than the partially damaged buildings. This outcome implies that residential buildings designed based on the revised seismic standards have good earthquake resistances. It also infers that the human deaths/injury casualties were not a result of the collapsed the structure, but due to the strong vibrations originated from the earthquake, yielding in the collapse of non-structural elements such as ceilings and bookshelves. This paper presents a proposed design philosophy that attempts to implement the effect of earthquakes to non-fatal human casualties.

  • Influence of Particle Size Distribution of High Calcium Fly Ash on HVFA
           Mortar Properties

    • Authors: Antoni ., Hendra Surya Wibawa, Djwantoro Hardjito
      Pages: 51 - 56
      Abstract: This study evaluates the effect of particle size distribution (PSD) of high calcium fly ash on high volume fly ash (HVFA) mortar characteristics. Four PSD variations of high calcium fly ash used were: unclassified fly ash and fly ash passing sieve No. 200, No. 325 and No. 400, respectively. The fly ash replacement ratio of the cementitious material ranged between 50-70%. The results show that with smaller fly ash particles size and higher levels of fly ash replacement, the workability of the mixture was increased with longer setting time. There was an increase in mortar compressive strength with finer fly ash particle size, compared to those with unclassified ones, with the highest strength was found at those with fly ash passing mesh No. 325. The increase was found due to better compactability of the mixture. Higher fly ash replacement reduced the mortar’s compressive strength, however, the rate was reduced when finer fly ash particles was used.

  • One Dimensional Site Response Analysis of Liquefaction Potential along
           Coastal Area of Bengkulu City, Indonesia

    • Authors: Lindung Zalbuin Mase
      Pages: 57 - 69
      Abstract: This paper presents one dimensional non-linear site response analysis of liquefaction potential caused by the 2000 and the 2007 earthquakes in coastal area of Bengkulu City, Bengkulu, Indonesia. Site investigations, including Standard Penetration Test (SPT) and shear wave velocity (VS) measurement, were conducted in three locations along the coastal area of Bengkulu City. Further, the site investigation data were used in simulation of one-dimensional non-linear site response analysis by applying the synthetic ground motions at bedrock. The results show that liquefaction could happen at 0 to 1.5 m deep. This was indicated by the excess pore water pressure ratio (ru) which exceeded one. At depth between 1.5 m and 20 m, the excess pore water pressure almost reached the initial effective stress decreasing the effective confinement pressure close to zero. The results also indicated that liquefaction is possible to occur in this depth range if a stronger earthquake occurs.

  • Displacement and Stress Function-based Linear and Quadratic Triangular
           Elements for Saint-Venant Torsional Problems

    • Authors: Joko Purnomo, Wong Foek Tjong, Wijaya W.C., Putra J.S.
      Pages: 70 - 77
      Abstract: Torsional problems commonly arise in frame structural members subjected to unsym­metrical loading. Saint-Venant proposed a semi inverse method to develop the exact theory of torsional bars of general cross sections. However, the solution to the problem using an analytical method for a complicated cross section is cumbersome. This paper presents the adoption of the Saint-Venant theory to develop a simple finite element program based on the displacement and stress function approaches using the standard linear and quadratic triangular elements. The displacement based approach is capable of evaluating torsional rigidity and shear stress distribution of homogeneous and nonhomogeneous; isotropic, orthotropic, and anisotropic materials; in singly and multiply-connected sections.  On the other hand, applications of the stress function approach are limited to the case of singly-connected isotropic sections only, due to the complexity on the boundary conditions. The results show that both approaches converge to exact solutions with high degree of accuracy.

  • Considering the Effect of Motorcyclist Risk Tolerance in Accident Risk
           Management: A Preliminary Study

    • Authors: Siti Malkhamah, Latif Budi Suparma, Don Gaspar Noesaku da Costa
      Pages: 78 - 85
      Abstract: Negative perceptions about accident are usually associated with speeding behavior. However, risk perception has not been considered in accident risk management. It is accepted as a personality matter, thus the number of accidents per year was used as accident risk tolerance indicator. Consequently, due to insufficient measurable indicators, it would be difficult to prevent the increasing speeding behavior. This paper discusses the improvement of accident risk tolerance indicators, i.e. safety factor and margin of safety, and their possible usage in speed management policies. These indicators were built based on the correlation between the results of interview and braking maneuver test. From this combine approach, using aggregated-individual and expert acceptance models, it was found that risk tolerance arose because motorcyclists accepted both the advantages and disadvantages gained from speeding, obtained through their riding frequency, duration of riding and/or accident involvement experienced. However, inappropriate speed due to miss-perception toward braking capability should be avoided. Inversely, an appropriate speed management should consider their travelling expectation

      Abstract: Buildings designed using older code should be checked against the higher demand required by newer code. In this study, performance of Building T of Petra Christian University, Surabaya, Indonesia, which was designed with older Indonesian Seismic Code (PPTGIUG 1983) is investigated. The effectiveness of VSL-Gensui Damper application is also investigated as an effort to enhance the performance of the building. Nonlinear time history analysis was conducted to analyze the building. Spectrum consistent ground acceleration generated from El Centro 18 May 1940 North-South component in accordance to current seismic code was used for analysis. The result shows that the existing building cannot resist the demand specified by current code (SNI 1726:2012) as some frame element failures are detected. The performance is greatly enhanced after installation of VSL-Gensui Dampers. Roof story drift and displacement decreased as much as 9% and 14%, respectively as compared to existing building, and structural element failures were no longer observed.

  • Improving Shear Strength Parameters of Sandy Soil using Enzyme-Mediated
           Calcite Precipitation Technique

    • Authors: Heriansyah Putra, Hideaki Yasuhara, Naoki Kinoshita, Erizal ., Tri Sudibyo
      Pages: 91 - 95
      Abstract: Several methods have been established for their various potential applications as soil improvement technique, and recently the application of grouting technique using biological process have been proposed. This study discussed the applicability of enzyme-mediated calcite precipitation (EMCP) in improving the shear strength parameters of sandy soil.  In this study, soil specimens were prepared and treated with the grouting solutions composed of urea, calcium chloride, magnesium sulfate and enzyme of urease. Evolutions in the cohesion and internal friction angle of the improved soil were examined through the direct shear tests. The presence of the precipitated materials, comprising 4.1 percent of the soil mass of the treated sand, generated a cohesion of 53 kPa. However, contrary to the improvement of cohesion, the friction angle is relatively constant. It indicated that the application of the EMCP technique has no significant impact on the friction angle

  • Initial Surface Absorption of Cement Combination Concrete

    • Authors: Samuel Olufemi Folagbade
      Pages: 96 - 101
      Abstract: This paper investigated the initial surface absorption (ISAT) of concrete using Portland cement (PC) and some binary and ternary cement combinations containing fly ash (FA), silica fume (SF) and metakaolin (MK) as partial replacements for PC at equal water/ cement ratios and strengths. At equal water/cement ratios, the cement combination concretes have higher ISAT values than PC concrete at 28 days and the disparity reduced with increasing curing age due to improved pozzolanic reactivity of the supplementary cementitious materials. SF and MK as binary and ternary cement components performed better than FA due to their higher fineness, improved particle packing and higher pozzolanic reactivity. At equal strengths, FA binary cement concretes have the lowest ISAT values and these reduced with increasing content of FA. At total replacement levels more than 20%, all the ternary cement concretes have lower ISAT values than PC concrete and the values reduced with increasing total replacement level due to the beneficial effect of FA.

           Construction Site Facilities

    • Authors: Doddy Prayogo, Jessica Chandra Sutanto, Hieronimus Enrico Suryo, Samuel Eric
      Pages: 102 - 110
      Abstract: A good arrangement of site layout on a construction project is a fundamental component of the project’s efficiency. Optimization on site layout is necessary in order to reduce the transportation cost of resources or personnel between facilities. Recently, the use of bio-inspired algorithms has received considerable critical attention in solving the engineering optimization problem. These methods have consistently provided better performance than traditional mathematical-based methods to a variety of engineering problems. This study compares the performance of particle swarm optimization (PSO), artificial bee colony (ABC), and symbiotic organisms search (SOS) algorithms in optimizing site layout planning problems. Three real-world case studies of layout optimization problems have been used in this study. The results show that SOS has a better performance in comparison to the other algorithms. Thus, this study provides useful insights to construction practitioners in the industry who are involved in dealing with optimization problems

  • A Numerical Investigation on the Structural Behavior of Deficient Steel
           Frames Strengthened using CFRP Composite

    • Authors: Amir Hamzah Keykha
      Pages: 1 - 7
      Abstract: Carbon fiber reinforced polymers (CFRP) is one of the materials that is used to strengthen steel structures. Most studies on CFRP strengthening steel on structures have been done on beams and steel columns. No independent study has studied the effect of CFRP strengthening on the structural behavior of steel frames having initial deficiency.The deficiency in steel structures may be created due to the errors caused by construction and others.This study aims to carry out a numerical study on the efficiency of CFRP sheet on strengthening square hollow section (SHS) steel frames having initial deficiency. Seven specimens, five of which were strengthened using CFRP sheets, were analyzed. ANSYS software was used to analyze the SHS steel frames. The results showed that the coverage length, the width, and the number of CFRP layers have a significant effect on increasing and recovering the ultimate load capacity of the SHS steel frames having initial deficiency.

  • Development of the DKMQ Element for Analysis of Composite Laminated Folded
           Plate Structures

    • Authors: Foek Tjong Wong, Kristofer Widjaja
      Pages: 8 - 15
      Abstract: The discrete-Kirchhoff Mindlin quadrilateral (DKMQ) element has recently been developed for analysis of composite laminated plates. This paper presents further development of the DKMQ for analysis of composite laminated folded plates. In this development, a local coordinate system is set up for each element at its centroid. The DKMQ stiffness matrix is superimposed with that of the standard four-node plane stress quadrilateral element to obtain a 24-by-24 folded plate stiffness matrix in the local coordinate system. To avoid singularity of the stiffness matrix, a small stiffness coefficient is added in the entries corresponding to the drilling degrees of freedom. The local stiffness matrix and force vector are then transformed to the global ones and assembled. The accuracy and convergence of the folded plate element are assessed using a number of numerical examples. The results show that the element is accurate and converge well to the reference solutions.

  • Stabilising Potential of Sawdust Lignin based Extracts in Compressed
           Lateritic Bricks

    • Authors: Fadele; O.A, Ata, O.J.
      Pages: 16 - 20
      Abstract: Lignocellulosic materials are abundant in nature, rich in some functional groups, considered less harmful to human health and the environment.The resulting waste may be recycled for other beneficial uses. Lignin is known to be a natural binder in lignocellulosic materials and several studies have confirmed it has binding ability with soil particles. This paper studied its stabilising potential in compressed lateritic bricks, especially its effects on density and compressive strength properties of the bricks. Lignin additives extracted from sawdust were used to stabilise laterite, while the bricks were moulded with the UNIFE ram, a type of the CINVA ram. The laterite was stabilised at 4%, 8% and 12%, while cement stabilised samples and 0% (unstabilised laterite) samples prepared accordingly were used as controls. The results showed that the LBAs contributed to the strength gained by the bricks at 3, 7, 14 and 28 days air curing, while the bricks samples were categorised as high density.

  • Metaheuristic-Based Machine Learning System for Prediction of Compressive
           Strength based on Concrete Mixture Properties and Early-Age Strength Test

    • Authors: Doddy Prayogo
      Pages: 21 - 29
      Abstract: Estimating the accurate concrete strength has become a critical issue in civil engi­neer­ing. The 28-day concrete cylinder test results depict the concrete's characteristic strength which was prepared and cast as part of the concrete work on the project. Waiting 28 days is important to guarantee the quality control of the procedure, even though it is a slow process. This research develops an advanced machine learning method to forecast the concrete compressive strength using the concrete mix proportion and early-age strength test results. Thirty-eight historical cases in total were used to create the intelligence prediction method. The results obtained indicate the effectiveness of the advanced hybrid machine learning strategy in forecasting the strength of the concrete with a comparatively high degree of accuracy calculated using 4 error indicators. As a result, the suggested study can provide a great advantage for construction project managers in decision-making procedures that depend on early strength results of the tests.

  • Wave Trajectory Study on the Coast of Lhoknga, Aceh Besar, Indonesia: A
           Numerical Model Approach

    • Authors: Ichsan Setiawan, Mohammad Irham
      Pages: 30 - 34
      Abstract: A numerical model of wave trajectory using shoaling and refraction formula was proposed in the coastal waters of Lhoknga, Aceh Besar, Indonesia. The developed model used a two dimensional (2D) numerical methods for wave trajectory with the input of wave height and period; 0.62 m and 8 second for high tide and 0.47 m and 6 second for low tide. This model was tested on site during low tide and high tide conditions for verification. The purpose of this numerical study is to trace the distribution of wave trajectory because of shoaling, wave breaking, and wave refraction. The model determines the wave height and crest pattern of the ray wave trajectory. The simulation result shows the pattern of the wave propagation at Lhoknga beach moves from the northwest to the east and south of the coast. The model also informs that the maximum wave height during high tide condition is 1.72 m and 1.31 m during low tide condition. The result indicates that the coast of Lhoknga has moderate wave conditions caused by a gentle beach bathymetry slope.

  • Performance of an Existing Reinforced Concrete Building Designed in
           Accordance to Older Indonesian Seismic Code: A Case Study for a Hotel in
           Kupang, Indonesia

    • Authors: Pamuda Pudjisuryadi, Benjamin Lumantarna, Ryan Setiawan, Christian Handoko
      Pages: 35 - 40
      Abstract: The recent seismic code SNI 1726-2012 is significantly different compared to the older code SNI 1726-2002. The seismic hazard map was significantly changed and the level of maximum considered earthquake was significantly increased. Therefore, buildings designed according to outdated code may not resist the higher demand required by newer code. In this study, seismic performance of Hotel X in Kupang, Indonesia which was designed based on SNI-1726-2002 is investigated. The structure was analyzed using Nonlinear Time History Analysis. The seismic load used was a spectrum consistent ground acceleration generated from El-Centro 18 May 1940 North-South component in accordance to SNI 1726-2012. The results show that Hotel X can resist maximum considered earthquake required by SNI 1726-2012. The maximum drift ratio is 0.81% which is lower than the limit set by FEMA 356-2000 (2%). Plastic hinge damage level is also lower than the allowance in ACMC 2001.

  • Evaluation of a Reinforced Concrete Wall Macroscopic Model for Coupled
           Nonlinear Shear-Flexure Interaction Response

    • Authors: Joko Purnomo, Jimmy Chandra
      Pages: 41 - 50
      Abstract: Reinforced concrete shear wall (RC wall) is an important element in tall buildings, which provides strength and stiffness against lateral loadings, e.g. earthquake and wind. Numerous researches have been conducted to study its nonlinear behavior via microscopic and macroscopic model. The later approach is currently being widely explored since it has many advantages compared to the preceding models. A well-known macroscopic model, namely Shear-Flexure-Interaction Multiple-Vertical-Line-Elements-Model (SFI-MVLEM) in the open source platform Open Sees, is capable of simulating the coupled nonlinear shear-flexure interaction response in the RC wall. This paper presents an evaluation to the applicability of SFI-MVLEM model to predict the coupled nonlinear shear-flexure behavior of RC wall specimens compared to experimental results in available literature. The analysis results show that the model is able to predict the behavior of RC wall considerably accurate in terms of hysteretic curves, cracking patterns, and contributions of shear and flexural displacement to total displacement.
