Abstract

Soil conditions with weak zone points can cause damage to road structures such asland subsidence. Geoelectric surveys can identify subsurface structures based onvariations in rock resistivity. Road infrastructure crash due to weak zones of soilbearing capacity can be identified by geoelectric surveys and geotechnical tests assupporting analysis. Based on the master plan of Politani Samarinda 2025-2029 inthe southern area, a ring road of ± 1.5 km will be built, so geoelectric andgeotechnical support data are first needed as a basis for road planning. The mainobjective of this study is to mapping subsurface structure and identify the stability ofthe strong and weak zones of the soil in the planned area of the ring roadconstruction. The geoelectric resistivity survey uses the Wenner Schlumbergerconfiguration with 2 longitudinal tracks of ± 100 m per track with a spacing (a) of 5m which can identify the distribution of subsurface resistivity values laterallymapping.The resistivity value obtained from 2D geoelectric inversion is the lowestvalue of 2.62 ohm.m which is suspected as clay, medium 78.5 ohm.m which issuspected as sand, and the highest 7716 ohm.m which is suspected as sandstoneand used as a reference in the strong zone of the road building foundation.Furthermore, the USCS classification geotechnical test at 2 track points resulted insand (SM) and silt clay (MH) soil types based on mechanical laboratory tests. Theresults of the identification of geoelectric surveys and geotechnical tests have asignificant correlation with road construction that has a potential strong zonebearing capacity because the top soil is in the form of silt, clay, sand which isunderneath in the form of sandstone which is strong enough to withstand the load ofroad construction.

Abstract

The increasing growth of infrastructure and building development has led to a reduction in land surface cover. The lack of surface cover significantly impacts the environment, such as causing severe flooding. To address water-related issues, one approach is to manage runoff at its source through Low Impact Development (LID) strategies, such as permeable pavements. One method used to infiltrate water is porous concrete. Key parameters of porous concrete include strength, water-cement ratio, porosity, and permeability coefficient. The permeability coefficient of porous concrete is obtained through permeability testing. Laboratory permeability tests are more commonly used than field-testing. Therefore, it is important to have a dedicated tool for testing the permeability of porous concrete. The first stage involves the development and testing of a prototype, which includes prototype design, material survey, material procurement, equipment preparation, prototype construction, and testing. The prototype development refers to the ACI 522R-10 standard. The results of the prototype testing are analyzed using Darcy’s law to determine the permeability coefficient and analyze the flow characteristics. Based on the research findings, the permeability test prototype for porous concrete can be used as a testing tool for porous concrete permeability both in laboratory and field settings. The prototype exhibits laminar flow, thus allowing Darcy’s law to be applied for evaluating hydraulic conductivity.

Abstract

Concrete with waste tire rubber powder is one of the approaches to utilizing rubber waste, which continues to increase in volume over time. This study aims to investigate in detail the effects of using waste tire rubber powder on the mechanical properties of concrete through experimental methods, with a focus on compressive strength and elastic modulus. The comparison results of compressive strength and elastic modulus are then analyzed using a forensic engineering approach to determine their impact on potential structural failures and their influence on the service life of the structure. The results of this study show that the use of rubber powder in the range of 2.5% to 10% as a fine aggregate substitute in concrete mixtures can reduce compressive strength and elastic modulus by approximately 16% to 28% for compressive strength, and 5% to 11% for elastic modulus. In terms of structural service life, the use of rubberized concrete can reduce the service life by approximately 22% to 27%. Rubberized concrete offers great potential in rubber waste utilization and in enhancing the sustainability of construction materials. However, from a forensic engineering perspective, rubberized concrete presents new challenges in understanding, evaluating, and predicting the long-term performance of structures.

Abstract

Simpang Bawen area connects Semarang with surrounding cities such as Salatiga, Surakarta, and Yogyakarta. Between 2017-2023, 98 accidents were recorded starting from Hortimart Agro Center to Simpang Exit Tol Bawen. This study aims to analyze the characteristics of traffic accidents, contributing geometric and operational design factors, and recommendations for safety improvements. The in-depth analysis method in qualitative descriptive research was used with accident data from the Semarang Police Traffic Unit and supporting data from the Central Java-Yogyakarta National Road Implementation Center. Field surveys were conducted to observe location conditions. The analysis was carried out by dividing the research location into five zones. The results of the analysis showed that the most frequent accident types varied in each zone and were dominated by motorcycles and heavy vehicles. Accidents occurred in sunny weather with moderate severity and were caused by non-priority behavior. Recommendations for improvement include closing U-turns, adding rumble strips, building flyovers, installing traffic lights, enforcing traffic laws, and improving street lighting.

Abstract

Lightweight concrete is an increasingly popular construction material because of its lightweight and high strength, so effective adhesive technology is needed to increase the adhesion between elements. This study aims to compare the effectiveness of the use of polyurethane glue with MU 380 on the variation of bonding time and shear strength of bonding in the installation of lightweight brick concrete. In this study, tests were conducted on lightweight brick concrete joints using two types of adhesives, namely polyurethane glue and mortar. The variation of bonding time applied to the application of polyurethane glue includes 5, 10, 15, 20, 25, 30, 60, 360, 720, and 1440 minutes. Meanwhile, for mortar adhesive, the bonding time used is 5, 10, 15, 20, 25, 30, 60, 360, 720, and 1440 minutes. After the application of glue and mortar, shear strength testing was carried out to determine how well the concrete joints can withstand shear loads. The results showed that polyurethane glue produced much higher shear strength than mortar at all bonding times tested. The highest average shear strength was obtained at a setting time of 25 minutes for polyurethane glue, which was 21.85 MPa, while the average maximum strength of the mortar occurred at a setting time of 360 minutes with a value of 3.123 MPa. In addition, the shorter setting time of polyurethane glue allows for better installation time efficiency.

Abstract

Soft clay soil, which is often found in coastal and lowland areas of Indonesia, has characteristics such as low bearing capacity, high plasticity, and easy to subside under load, making it a challenge in infrastructure projects. Various soil stabilization methods have been developed, one of which is the use of chemical stabilizers. This study examines the use of Calcite (CaCO3) and Spent Catalyst RCC 15 as stabilization materials to improve the quality of soft clay soil. Calcite is known to reduce plasticity and increase soil bearing capacity, while Spent Catalyst RCC 15, as industrial waste, has the potential to improve soil structure and increase soil stability. Tests were conducted in the laboratory by mixing 6% Calcite and variations of Spent Catalyst RCC 15 (0%, 4%, and 8%) in soil samples from Cililin, West Java. The test results showed that the combination of Calcite and Spent Catalyst RCC 15 significantly increased the California Bearing Ratio (CBR) value of the soil, which means increasing the soil bearing capacity. The higher the percentage of Spent Catalyst RCC 15, the higher the CBR value obtained, indicating the effectiveness of this combination of stabilization materials in improving soft clay soil. These findings indicate the potential for an economical and sustainable solution to address soft clay soil problems in Indonesia and support more environmentally friendly industrial waste management.

Abstract

The availability of clean water is a fundamental need that is crucial for the survival of all living beings, including humans. Katapang Hamlet, located in Lokki Village, Huamual District, West Seram Regency, faces serious issues related to the distribution of clean water due to frequent pipeline system failures, particularly caused by flooding. The pipeline system in this area has been built three times, but it continues to experience damage, affecting the clean water distribution to the community. The current system is highly vulnerable to natural disasters such as floods, with pipelines located in high-risk areas like riverbanks and steep cliffs, irregular pipeline routes, and inadequate system components. During floods, the community often goes without a clean water supply for days. To address this problem, a redesign of the clean water distribution network is required. This study aims to design an optimal clean water distribution system using Epanet 2.2 software. Through this application, the analysis and simulation of the distribution pipeline network are carried out to ensure that the system continues to function well, even during heavy rain or floods, so that the community can consistently receive a clean water supply. The results of this study are expected to provide a long-term solution to the clean water distribution problems in Katapang Hamlet.
