Abstract

Indonesia was located in a seismically active region and was situated between three tectonic plates. The construction resilience that met the requirements was necessary in earthquake-prone areas. The purpose was to protect and reduce the risk of severe damage caused by significant seismic loads. However, more than 70% of buildings in developing countries like Indonesia utilized the Confined Masonry (CM) structural system. The implementation of CM systems in Indonesia often led to fatal damages during earthquakes. Due to the severity of these damages, the addition of reinforcement systems to CM became one of the options to address the shortcomings of the CM system. There were various types of materials that could be used as reinforcement, such as steel cages, polymers, polypropylene bands, bamboo meshes, and plastic materials. This study investigated the utilization of ferrocement layers as reinforcement material for CM structural system panels. The specimen panels used had a width of 2300 mm and a height of 1370 mm. The specimens in the research were numerically modeled using the ABAQUS/explicit program. The research variation focused on the influence of the wiremesh sheet orientation angle. The number of variations for the ferrocement layer was one layer with angle configurations of 0, 45, and 60 degrees. This reinforcement layer was applied to one side of the CM panel. As a comparison, results from the control specimen were included. The hysteresis curve, energy dissipation, stiffness degradation, and damage patterns were evaluated in this research.

Abstract

Indonesian houses are characterized as non-engineered and vernacular, constructed using local material, techniques, and architectural style. As a results these houses are typically built without the involvement of experts. In Indonesia, most lower class houses are unreinforced masonry (URM), masonry without structural elements. The absence of structural elements makes URM highly vulnerable to earthquakes and makes the masonry walls the main load bearers. This study analyses the performance of corner joint masonry wall with perforated plate to enhance the integrity between the perpendicular walls. This research was carried out experimentally. The results indicate that URM joint corner walls without perforated plates has the highest load capacity and ductility. Perforated plates in layers of masonry walls can decrease the lateral load capacity by 55%. The failure pattern occurred are slip failure, with cracks appearing at mortar-brick joint and mortar-perforated plate interfaces. From the test that have been carried out, it was found that perforated plate could reduce the cohesiveness of the walls rather than enhance the integrity of the perpendicular walls.

Abstract

This paper describes significant wave height downscaling model in south sea around Banyuwangi and Bali. It utilizes 3rd Generation Simulating Wave Nearshore (SWAN) spectral model forced by ERA-5 Reanalysis data of wind and wave. The downscale is done using refined grid in Kuta Beach and Nusa Dua Beach. Model calibration conducted in the offshore and nearshore areas. The offshore wave results are validated using altimeter data, while the nearshore wave results are compared with site measurement in Kuta Beach and Nusa Dua Beach. A parametric study is performed to obtain model sensitivity and compared with observation, such as: wind multiplier factor, bottom friction coefficient, whitecapping, and wave breaking parameter. The model result gives good agreement with altimeter data. Indeed, the wind multiplier factor can be used as one calibration parameter in the wave model. The comparison with measured data shows good agreement in Kuta Beach, where the model can predict the nearshore wave transformation from offshore. Although, in Nusa Dua Beach the model nearshore wave transformation shows more dissipation if compared with wave measurement. Indeed, the downscaling process shows it can be used further in wave climate prediction after calibrated with measurement.

Abstract

High-rise building construction projects are characterized by significant risks and numerous challenges, which frequently lead to low productivity, causing delays and hindering project completion. One way to address these problems is to analyze the risk factors of low productivity in construction projects using a clustering method based on their probability and impact. This approach helps determine the dominance level of each cluster and provides insights into the occurrence of risk factors that affect low productivity in high-rise building projects in Surabaya City. This research was conducted with surveys filled out by 37 respondents involved in four high-rise building projects in Surabaya City. The aim of this study is to analyze risk factor clustering and determine the dominance of each cluster affecting low productivity in high-rise building projects in Surabaya City by employing the Agglomerative Hierarchical Clustering method to identify clusters and determine the most dominant cluster using Euclidean Distance. From the literature review, 33 risk factors were identified as the variables of this research. The AHC method was carried out based on the mean probability and impact of each cluster obtained from the survey. The result of AHC is that Cluster 1 consists of 23 factors, Cluster 2 consists of 5 factors, and Cluster 3 consists of 5 factors. For the dominance level of each cluster, the Euclidean distance method was carried out, and the result was that Cluster 2 emerged as the highest overall risk, and Cluster 3 represented a low overall risk.

Abstract

As the population increases, the level of activity and mobility will also increase. To facilitate people's movement, the Indonesian Government built infrastructure in the form of toll roads. The Trans-Java Toll Road stretches between Merak Harbor, Cilegon, Banten Province, and Ketapang Harbor, Banyuwangi, East Java Province. The Surabaya-Banyuwangi section is currently in the development stage. The existence of the Banyuwangi-Surabaya toll road will impact behavioural patterns in using transportation modes. Currently, several modes of land transportation can be used, i.e., buses via toll and non-toll (economy), trains, and private cars. The current travel time from Banyuwangi-Surabaya is 6 hours 30 minutes using a toll bus and 8 hours 15 minutes using a non-toll bus. In comparison, the travel time for the Wijayakusuma train mode (Banyuwangi-Surabaya) is 6 hours 2 minutes. Private vehicles (cars) also use a variety of different routes, causing the travel time and travel costs of private cars to be affected. Differences in travel time and routes used due to the existence of the Banyuwangi-Surabaya toll road change mode preferences between toll buses, non-toll buses (economy), trains, and private vehicles (cars). This research is a model for selecting transportation modes for the Banyuwangi-Surabaya route using the split modal method with an exponential function or difference function (β) with a value of NMAE= 0.0000087, where the NMAE value is close to 0, and can be used to estimate the proportion of modal choices on the Banyuwangi Surabaya route.

Abstract

This research evaluates the mechanical properties and fracture behaviour of ethylene-vinyl acetate (EVA) polymer-modified warm mix asphalt under the influence of ageing simulated through oven heating at 85oC in two different durations of 2 and 8 days. EVA contents of 4 - 6% of binder weight were employed, and the effect was measured through the semi-circular bending (SCB) test. Volumetric properties measurement showed negligible effect of polymer addition, with the difference in air void ratio ranging from 0.5% to 8% compared to the control mix. Meanwhile, the density and void in mineral aggregate (VMA) differed by a maximum of 2% compared with the control mixture. Moreover, the increase in the heating period was found to enhance the tensile strength, with a maximum difference of 81.72% exhibited by the mix with 0.5% EVA, corresponding to its tensile strength from the 8-day ageing conditioning by 28% larger than the control mix. Moreover, crack resistance and flexibility indexes (CRI and FI) were inversely proportional to the increase of polymer dosages for both 2- and 8-day aged specimens from being 20.5% and 52% to 6.4% and 18.3% larger than the control mixture, respectively, with the 8-day aged specimens having the CRI of 8% larger and FI of 8.7% smaller than the 2-day aged samples, indicating a brittle behaviour in respect to the ageing duration. Conclusively, the heating ageing simulation results in a brittle asphaltic mixture modified with EVA, displayed with higher strength and lower flexibility, particularly at 5% to 6% w/t.

Abstract

The palm oil processing industry in Indonesia has experienced significant growth, bringing both positive economic impacts and negative consequences, specifically the generation of spent bleaching earth (SBE), a waste product of bleaching earth. Despite its potential as a substitute material for cement due to its pozzolanic properties, challenges arise from SBE's oil content. Hence, this study introduces pre-treatment methods involving extraction and calcination to optimize the use of SBE, referred to as Pre-treated Spent Bleaching Earth (PSBE). This research aims to analyze the optimized PSBE material through the optimization of the pre-treatment process in the usage of mortar. The optimized PSBE is compared to another supplementary cementitious material, which is fly ash to see the performance of optimized PSBE as supplementary cementitious material. The performance of the mortar was evaluated through tests including slump test, compressive strength test, and mortar hydration temperature analysis. The pre-treatment process of SBE was optimized by combining extraction and calcination methods, which yielded the most effective results from oil content test. One of the performance analysis results showed that the compressive strength test revealed a 28-day compressive strength value of 50,22 MPa for the optimized PSBE mortar, while the fly ash mortar had a compressive strength of 37,36 MPa. In conclusion, the optimized PSBE shows promising potential as a supplementary cementitious material.

Abstract

Kualanamu Airport railway transportation has yet to become the public's leading choice for commuting to Kualanamu Airport because, according to the public, the rates set are still relatively expensive. So, further research is needed on the level of passenger satisfaction, ability to pay (ATP), and willingness to pay (WTP) so that tariffs can be determined according to people's ability and willingness to pay. The method used in this research includes distributing questionnaires and interviews using stated preference techniques. The methods used in this research are the importance-performance analysis (IPA) method and the household budget method. The main priority for the level of satisfaction that needs to be improved is the attribute in quadrant 1 (A), namely the time interval between Kualanamu Airport train, Kualanamu Airport train operational schedules, and Kualanamu Airport train ticket prices. The ability to pay (ATP) for train users at Kualanamu Airport is IDR 79,000. Willingness to pay (WTP) from Kualanamu Airport train users is IDR 49,000.

Abstract

 Slope failure is caused by many factors, mainly high rainfall, especially in a tropical country like Indonesia. Many solutions have been expanded to do remediation of slope failure. However, establishing the best solution method is difficult because of many geotechnical challenges and different situations at the site. In addition, fast rate construction in line with a good quality of stability aspect is necessary to be attained. Therefore, a comparative study of two common solution methods, namely conventional cantilever wall and mechanically stabilized earth wall, was conducted to determine the best solution for slope failure remediation in the case studied. The analysis was performed by using a computer software program coded Geo5. A slope failure case in Bali was selected to investigate the performance of both studied methods in meeting all engineering criteria, including bearing capacity, internal stability (overturning and sliding), and global stability. The results show that mechanically stabilized earth wall gives more advantage not only in meeting all criteria but also in providing aesthetic concern and sustainable performance. On the other hand, conventional cantilever walls show a deficiency in global stability that will require pile foundation support or another reinforcement under the base plate, which will automatically increase construction time. The use of computer software will provide a more sophisticated analysis to examine various slope failure remediation methods to establish the most suitable solution for the specific sites. There is still expansive room to be researched in this area.

Abstract

Geopolymer concrete, an eco-friendly alternative, employs silica, alumina, and alkaline activators. While wet mixing has been extensively studied, its limitations, such as impracticality, quick setting, and low workability, are overcome by the dry mixing method. Study by previous research is limited only to compressive strength, flexural strength, and shrinkage. However, research on bond strength, crucial for concrete-reinforcement adhesion, is limited. This study investigates bond strength through pull-out tests using consistent concrete materials, including Type C fly ash, 12M NaOH, and an alkali ratio of 1:1. Specimens with varying reinforcement diameters (D10, D12, D16) and additional transverse reinforcement (f6-150) were tested. Bond stress averages at D10, D12, and D16 are 25.80 MPa, 25.36 MPa, and 24.25 MPa. Reinforcement diameter directly influences bond strength, with larger diameters yielding greater bond stress.
