Authors: Paramashanti  , Larasati D A 
Published: November 2020

Abstract
Case studies were carried out for unbraced monopod structures located in the Java Sea by reviewing the value of the reliability index. This sea has a depth of 33 meters and a 100-yr wave height of 6.29 meters. The structures are designed optimally with a unity check ratio of 1.00 using API RP 2A WSD and API RP 2A LRFD standards under storm condition, assumed to be unmanned. For LRFD criteria, the value of the environmental load factor is varied, namely 1.35, 1.20, 1.10, and 1.00. Collapse analysis using static pushover analysis of the model produces a minimum RSR value meeting the minimum criteria for un-manned structures of 1.6. The reliability analysis process uses the First Order Reliability Method II (FORM II). The structural reliability index value has met the minimum criteria issued by DNV of 3.71 for the structure that is designed using the environmental load factor of 1.35. It can be concluded for unbraced monopod structures designed in the Java Sea, the environmental load factor value of 1.35 is following the minimum reliability index value proposed by DNV.

Published: November 2020

Abstract
Wind load is often defined as a static uniform distributed load in the design code, especially on small structures such as billboard, pedestrian cross bridge, etc. However, as a fluid, wind can deform from a laminar flow to a turbulence flow or it can also be amplified if enough disturbance around the object exists. If these small structures are not designed for a dynamic load or the corrected amplified load, it will collapse. This study aims to investigate the effect of street canyon width towards wind flow by observing a simplified model of 4 symmetrical high-rise buildings with changing street canyon width. The numerical model uses CFD with RANS in OpenFOAM v1912 which is validated with experimental results using a low wind speed wind tunnel and Particle Image Velocimetry (PIV). An Experiment has been performed in BBTA3 using a model with 1:420 scale, there are 2 models with different street canyon width. The result showed there is an increment of the mean wind speed about 5.92-20.20%.

Published: November 2020

Abstract
This article studies about Rapid Visual Assessment using android application RViSITS. The Institut Teknologi Sepuluh Nopember team has developed this application, and the purpose is to conduct a more accessible assessment survey in the digital version instead of using the standard form, applying the same standard called FEMA 154. This building vulnerability research was carried out using the application, due to data requirement for mitigation action needed by Surabaya government, due to two newly discovered faults passing the city, namely Surabaya and Waru faults. These two new faults concealed by the National Earthquake Research Centre (PuSGeN) lead to higher earthquake potential hazards in Surabaya, as stated in the SNI 1726. In this research, a two-phase survey was conducted to a total of 366 buildings. From the development of the result mapping of the application, it is discovered that the buildings built after SNI 1726 regulation issued have a higher level of resistance toward earthquake loads, especially the buildings in Surabaya, where gradual seismic risks keep increasing. Therefore, it is necessary to develop mitigation strategies due to the earthquake potential hazard in Surabaya.

Authors: Karjanto A , Nindyawati  , Susanto P B 
Published: November 2020

Abstract
The objective of this study is to see whether or not there is a difference in the flexure behavior between three-supported continued segmental precast concrete beam joined with a cast in place. The formation of the bond is 90° vertical combined with 45° against the horizontal reinforcement, making use of the beam as the formwork. The monotonic pressure was applied constantly at one stage until the beams reached the ultimate. The result of the experiment showed that the flexure behavior of the three-supported continued pre-cast beams joined with the cast in place at the condition before cracks (elastic) had the same trend as that of monolith beam at the base area, as well as at the supporting points. However, before passing the yielding condition (the pulling reinforcer yielded), the precast beam had broken into pieces at the supported area, while the monolith beam had a trend in elastic condition, yielding condition, and ultimate condition. The ductility value of the pre-cast beam was 1.33 (at the base area) and 1,5 (at the supported area). The ductility value of the pre-cast beam was 1.0 at the base as well as at the supported area. This means pre-cast beams reach ultimate before the iron reinforcer yield (the ultimate structure is collapse). The cracking patterns showed that at the joined area the bonding failed to happen between the pre-cast beam and the bonding agent.
A simplified method to estimate the fundamental frequency of simple span bridges supported on lead rubber bearing
Authors: Sugihardjo H , Habieb A B 
Published: November 2020

Abstract
The impulsive load method applied on the mid-span of a girder is often used to measure the fundamental frequency of the bridge. This method commonly involves a truck that is dropped from a certain height to generate an impulsive load. In high seismicity zones, bridge structures often involve base isolators such as lead rubber bearing (LRB) to reduce the seismic force demand. However, the application of LRBs on the bridge girders may reduce its vertical fundamental frequency. This fundamental frequency may decrease further if the girder is supported on the frames or cantilever beams on high columns. In this study, the fundamental frequency of several bridge spans is computed through a simplified analytical study based on a single degree of freedom assumption. The results show that the application of LRBs does not significantly affect the fundamental frequency of the girder when compared to the identical girder supported on hinge-roller supports, due to the high vertical stiffness of the LRBs. In average, the values of fundamental frequency obtained through the simplified method and the FE modeling are lower than which obtained from the dynamic loading test. It indicates that the stiffness of the existing bridge is higher than the analyses.

Abstract
In steel frame structures, the connection is very important element to design, especially for earthquake resistant structures. How to choose the material and and dimension are very important things in steel connection to receive the load. Nowadays, the application of joints using extended end-plate has become popular because of it easy fabrication, the erection, and precise seismic performance. This connection is used to connect beam to column or connect the two beams. As a study material, we’ll make the detail of steel connection due to cyclic load using Abaqus 2017. In this research, we will remodel the connection from previous research with a end-plate modification using finite element method. The dimension of beam is I - 360 × 170 × 12 × 8 and the column is I - 213 × 222 × 10 × 7 with the thickness of end plate is 15 mm and using Grade 8.8 bolts. There are 3 types variation model, one for verification of previous research, and the other two were modified connections. The result of the study is Extended End-Plate can affect the value of the displacement. Connection using Extended End-Plate has smaller displacements, so its better to receive the loads that can cause the collapse. Extended End-Plate also affects the value of lateral load that can be borne. Connection using Extended End-Plate can receive the greater lateral loads, so its more stable and stronger to holding the loads. From the three specimens analyzed, the first model has the best performance where there are extended end plates on both sides.

Abstract
This paper presents the experimental investigations in studying the durability performance of normal concrete and engineered cementitious composite (ECC) under varying key influencing factors. To this end, direct measurements on sorptivity, water absorption and rapid chloride penetration were undertaken for both normal concrete and ECC; each of which was tested using 67-mm thick sliced cylinder specimens with a diameter of 100 mm. The results from this studies highlight that the inherent low permeability properties in ECC are shown to provide excellent durability performance, in particular to the improvement of sorptivity rate and water absorption which is twice higher than that of normal concrete, indicating the very dense capillary pores microstructure. It is also found that chloride concentration on the surface of ECC is twice lesser than normal concrete, owing to the fact marginal manifestation of the electrical conductance.
Railway capacity analysis using Indonesian method and UIC code 405 method
Authors: Widyastuti H , Budhi W S 
Published: November 2020

Abstract
The government has been constructing double track at Surabaya-Madiun segment to improve railway operations performance. Accordingly, after the double track has been constructed in this segment, it is necessary to analyze existing railway capacity to determine the effect of development as a cost-effective solution. Nowadays, Indonesia is using the Indonesian method as a capacity analysis method and only provides railway capacity analysis using fixed block. On the other hand, another method such as the UIC method has different variables. Therefore in this study, the railway capacity analysis uses two analytic methods that are Indonesian and UIC code 405. The analysis result of both methods shows an improvement in railway capacity because of the double-track construction. These two methods have different results due to each variable. Moreover, one of the UIC variables is additional time due to maintenance differentiated based on its utilization. Utilization in the UIC method is differenced based on its operational conditions by peak and non-peak hours or normal conditions that may also affect the capacity. It also happens in MRT Jakarta operating systems in which the headway is divided into peak and non-peak hours. Accordingly, this study could be a preliminary study for policymakers to analyze capacity in the next near future condition.
Intercity train dwell time estimation by using robust regression method: a study case on Surabaya-Yogyakarta line
Authors: Dewi P , Widyastuti H 
Published: November 2020

Abstract
Dwell time is important an issue to optimise not only for train operation efficiency but also punctuality. This paper proposes a model based on a field survey of intercity trains along the Surabaya-Yogyakarta line by using a robust regression analysis of 138 observations from 13 trainsets operating on the line. Assuming no differences in door or platform width, a model has been formulated to include the number of people who are alighting and boarding, the type of platform and the number of train doors on one side. There were three robust estimators applied to the model. With a 2.037% mean absolute percentage error, the robust regression using the M estimator formed the dwell time model for this study. The results show that, between the dummy variable for platform type using a binary number (0 or 1), dummy variables for high-level platforms and mid-level platforms have opposing tendencies. High-level platform use reduces dwell time by 2.014 sec based on continuous variables; in contrast, dwell time increases by 9.353 sec based on continuous variables by using mid-level platforms. Furthermore, people who are alighting need less time than those boarding. Dwell time will increase by 1.222 sec per alighting passenger and 1.314 per boarding passenger, while it will decrease by 2.727 sec per door on a one-sided trainset. Moreover, dwell time estimates with the model have reduced trainset travel time.

Authors: Kasaf M , Prastyanto C A 
Published: November 2020

Abstract
Aggregates are the largest component of the flexible pavement structure. The quality of the road is largely determined by the nature and type of aggregates used. Currently, the development of road infrastructure in Indonesia continues to experience increasing amount of natural aggregate use, so this will cause the availability of natural aggregate raw materials to continue to thin out. For that reason, an effort should be made to find alternatives to the use of natural aggregates, one of which is the utilization of steel slag. In this study, it will be examined the characteristics of the steel slag aggregates by referring to the 2018 Bina Marga specifications and the Marshall characteristic test method. This study used steel slag addition with variations of 0%, 50%, 80% and 100%. The results obtained in this study are that the value characteristics of the slag aggregate meet the standard specifications. The use of steel slag at 80% variation in coarse aggregate produces the best stability value which is equal to 2320,19 Kg. Overall, the use of steel slag can be an alternative to the use of natural aggregates. Moreover, steel slag can also be an alternative to an effort to reduce waste.

Authors: Idfi G , Rahayuningsih T , Suryoputro N 
Published: November 2020

Abstract
Flooding occurs when rain runoff water cannot be accommodated by a river, due to the flow of water that exceeds its drainage capacity. Flooding can occur anywhere, one of which occurs in the Kemuning river, Sampang Regency. The existing ag factor of the river profile that is experiencing siltation is also a cause of flooding, especially in the rainy season. This study aims to reduce flood discharge in the Kemuning river by planning a diversion channel as a solution using HEC HMS and HEC RAS modeling. Diversion channel is a divider discharge channel or shortcut to reduce flood discharge in rivers that flow directly into the sea. In this study three alternative solutions are planned, alternative 1 is planned to use a rectangular cross-section, alternative 2 is planned to use a trapezoidal cross-section and alternative 3 is planned to use a trapezoidal cross-section and adding and raising existing river embankments. The results of the analysis and planning showed that the flood discharge plan for the 25 year return period in the HEC HMS modeling was 781.9 m3/sec. The results of the HEC RAS modeling with flood hydrograph input during the 25-year return period, Kemuning river conditions overtopping at all stations as high as 1-4 m. From the trial and error results in the HEC RAS modeling, the maximum capacity of the Kemuning river is 90 m3 / second. Based on the maximum capacity of the Kemuning river, alternative diversion channels 1 and alternative 2 are planned to accommodate flood discharge of 681.9 m3 / sec. An alternative diversion channel 3 is planned to only discharge flood discharges of 300 m3 / sec by adding and raising embankments on the Kemuning river. All alternative diversion channel planning can reduce flood discharge by a percentage of 88.5% for alternatives 1 and 2, 38.4% for alternative 3. Based on the maximum capacity of the Kemuning river, alternative diversion channels 1 and alternative 2 are planned to accommodate flood discharge of 681.9 m3 / sec.

Published: November 2020

Abstract
Global warming resulting in climate change has become a new disaster in the world. One of the changes in climate is the rise of sea water to land surface, which causes tidal flooding. One area that experienced tidal flooding was Kawunganten District, Cilacap, Central Java Province. The area is traversed by the Parit River with the river estuary located in Ujungmanik Village. The problem of tidal flooding in Kawunganten District can be overcome by constructing a moveable weir in the estuary of the Parit River. In planning on the moveable weir, a hydrological analysis is needed to determine the flood discharge plan. Rainfall data used as a basis for calculation of flood discharge at the study site is rainfall data from 3 observation stations namely Cilacap Station, Majenang Station and Ujungbarang Station with the recording period from 2009 to 2018. Calculation of rainfall plan is done using the Pearson Log Method III with a value of T100 = 165.463 mm. The results of the calculation of the flood discharge plan with the haspers method Q100 = 280.989 m3/sec, while the weduwen method Q100 = 132.804 m3/sec and the HSS Nakayasu method Q100 = 102.444. Furthermore, an analysis of tides on the coast of Cilacap Regency with the results of MWL (Mean Water Level) = 110 cm, LWL (Low Water Level) = 20 cm, HWL (High Water Level) = 220 cm.

Directed self-assembly of spheroids into modular vascular beds for engineering large tissue constructs
Authors: Carvalho Daniel T O , Feijão Tália , Neves Mariana I , da Silva Ricardo M P , Barrias Cristina C 
Published: November 2020

Abstract
Spheroids can be used as building-blocks for bottom-up generation of artificial vascular beds, but current biofabrication strategies are often time-consuming and complex. Also, pre-optimization of single spheroid properties is often neglected. Here, we report a simple setup for rapid biomanufacturing of spheroid-based patch-like vascular beds. Prior to patch assembly, spheroids combining mesenchymal stem/stromal cells (MSCs) and outgrowth endothelial cells (OECs) at different ratios (10:1; 5:1; 1:1; 1:5) were formed in non-adhesive microwells and monitored along 7 d. Optimal OEC retention and organization was observed at 1:1 MSC/OEC ratio. Dynamic remodelling of spheroids led to changes in both cellular and extracellular matrix components (ECMs) over time. Some OEC formed internal clusters, while others organized into a peripheral monolayer, stabilized by ECM and pericyte-like cells, with concomitant increase in surface stiffness. Along spheroid culture, OEC switched from an active to a quiescent state, and their endothelial sprouting potential was significantly abrogated, suggesting that immature spheroids may be more therapeutically relevant. Non-adhesive moulds were subsequently used for triggering rapid, one-step, spheroid formation/fusion into square-shaped patches, with spheroids uniformly interspaced via a thin cell layer. The high surface area, endothelial sprouting potential, and scalability of the developed spheroid-based patches make them stand out as artificial vascular beds for modular engineering of large tissue constructs.
