Abstract

Self-Compacting Concrete (SCC) is an innovative concrete that can flow and compact itself without a compactor, making it highly effective for use in structures with dense reinforcement and complex shapes. However, the high cement requirements of SCC increase costs and carbon emissions, necessitating alternatives in the form of pozzolanic material substitutions such as fly ash and silica fume. This study aimed to analyze the effect of these two materials on the compressive and splitting tensile strength of SCC concrete through experimental methods with substitution variations of 0%, 10%, and 15% of the cement weight, as well as testing of fresh properties according to standards. The results showed that pozzolanic material substitution improved the mechanical performance of SCC, but to varying degrees. The addition of 10% fly ash only provided a moderate increase in compressive strength of approximately 4% at 28 days and had no significant effect on splitting tensile strength. On the other hand, 10% silica fume proved to be the most optimal composition because it produced the highest compressive strength of 57.49 MPa (an increase of about 28% from normal concrete) and increased the splitting tensile strength to 3.58 MPa, making it more effective for high-quality SCC.

Abstract

Asphalt Concrete Wearing Course (AC-WC) is a wearing layer on flexible pavements that directly receives traffic loads and environmental influences. However, conventional mixtures are still susceptible to plastic deformation, fatigue cracking, and water damage, so material modification is needed to improve their performance. This study aims to analyze the effect of adding latex and rice husk ash on the Marshall characteristics of AC-WC and to determine the optimal mixture variation. Laboratory experimental methods were used with 60/70 penetration asphalt, aggregates in accordance with the 2025 General Specifications for Highways, latex as an additive, and rice husk ash as a filler, with variations of 0%, 4%, 7%, and 9% latex and 0%, 3%, 6%, and 7% rice husk ash. Marshall test results showed that the combination of materials significantly affected the stability, flow, and stiffness of the mixture, while still meeting Bina Marga technical requirements. The best mixture was obtained with 3% latex and 6% rice husk ash, with VIM 4.82%, VMA 21.63%, VFB 78.01%, stability 831.17 kg, flow 3.73 mm, and MQ 222.33 kg/mm, making this variation recommended as the optimal and environmentally friendly AC-WC mixture.

Abstract

The Kendal Industrial Park (KIK), Central Java, is characterized by soft clay soil with low bearing capacity, requiring improvement before being used as a construction foundation. This study aims to determine soil classification, analyze the effect of ferronickel slag and alkali (NaOH and KOH) mixtures, and evaluate the potential of these mixtures as soil stabilization materials. The research was conducted experimentally in the laboratory through specific gravity tests, grain size distribution analysis, Atterberg limits, Standard Proctor compaction test, direct shear test, and California Bearing Ratio (CBR) test. The mixture variations used consisted of 10% ferronickel slag combined with alkali solutions of NaOH and KOH at concentrations of 6%, 8%, and 10%. The results showed that the original soil was classified as fine-grained soil with high plasticity and a CBR value of 5.6%, indicating low bearing capacity. The addition of ferronickel slag and alkali reduced soil plasticity and increased soil strength and bearing capacity. Therefore, the mixture of ferronickel slag and alkali has the potential to be used as an environmentally friendly alternative soil stabilization material.

Abstract

This study evaluates Occupational Health and Safety (OHS) performance in the Ibrahim Tower Phase 1 Construction Project at Roemani Muhammadiyah Hospital, Semarang, using a field-based empirical quantitative descriptive-evaluative approach. The research integrates hazard identification, frequency rate measurement, and assessment of preventive implementation to determine overall safety performance. From 203 identified potential hazards within the project’s SMK3 documentation, 39 were verified as actual occurrences, representing 19.21 percent of the total identified hazards. Frequency Rate calculations based on 985,600 working hours indicate that all actual hazard variables fall within the low-risk category (FR ≤ 5), demonstrating controlled accident intensity. Questionnaire analysis involving managerial and operational personnel reveals good to very good levels of preventive implementation, supporting the low frequency findings. The integration of documented safety systems, empirical verification, quantitative risk measurement, and organizational commitment suggests that the project’s OHS management system functions effectively.

Abstract

The growth of urban activities in Semarang City has led to an increase in traffic movement, particularly along Jalan Majapahit, which serves as a primary corridor connecting the city center with residential and industrial areas. Road rehabilitation works on this segment caused lane narrowing, resulting in reduced road capacity and affecting overall traffic performance. This study aims to analyze traffic characteristics and road performance on Jalan Majapahit before and during the road rehabilitation period. The evaluated parameters include traffic volume, side friction, road capacity, degree of saturation (DS), and level of service (LOS), based on the Indonesian Road Capacity Guidelines (PKJI 2023). The research method involved field surveys consisting of vehicle volume counts, side friction observations, and geometric road measurements. The collected data were then analyzed to determine road capacity and degree of saturation under both conditions. The results indicate that before rehabilitation, the degree of saturation reached approximately 0.736, representing relatively stable traffic conditions. However, during the rehabilitation period, the DS increased to 1.192, indicating that traffic demand exceeded road capacity, leading to congestion, reduced vehicle speeds, and traffic queues. Consequently, the level of service deteriorated from category C before rehabilitation to category E during rehabilitation

Abstract

Pile foundations play an important role in ensuring the stability of multi storey buildings subjected to axial loads, lateral loads, and moments. In the Batang III Industrial Worker Housing Project (JTGRSN21-03), the original foundation system used bored piles. This study redesigns the foundation into spun piles with a diameter of 0.80 m and a length of 12 m under the same soil conditions and loads. The research methodology was conducted through analysis of three foundation joints. Axial bearing capacity was evaluated using the Meyerhof method, resulting in a tip resistance of 946.00 kN, skin friction resistance of 2,970.37 kN, ultimate bearing capacity of 3,916.37 kN, and allowable bearing capacity of 1,305.46 kN. Lateral bearing capacity was analyzed using the Broms method with an allowable capacity of 162.0 kN. Group pile bearing capacity was determined using the Converse Labarre method. Settlement analysis using the Vesic method showed a single pile settlement of 22.69 mm and group settlements of 50.2 mm at joint 599, 41.8 mm at joint 628, and 21.0 mm at joint 371. Plaxis analysis produced smaller settlements of 13.94 mm, 13.44 mm, and 9.19 mm. The pile cap and shear wall design is considered safe.

Abstract

The construction sector significantly contributes to global energy consumption and carbon emissions, necessitating integrated strategies that combine operational efficiency and environmental sustainability. This study develops a conceptual Lean–Green integration model for construction projects in Manokwari through a Systematic Literature Review following the PRISMA protocol. The analysis synthesizes empirical findings published between 2018 and 2026 to examine the causal relationships between Lean Construction practices and Green Building performance indicators. The results indicate that Lean–Green integration potentially reduces material waste by 15–35%, decreases project costs by 10–20%, and improves operational energy efficiency by up to 30%. The proposed input–process–output framework identifies managerial commitment, workforce capability, regulatory support, and digital technology integration as critical determinants of successful implementation. The discussion highlights organizational culture, risk management, supply chain integration, and BIM-based digitalization as strategic enablers in peripheral regions with logistical constraints.

Abstract

Paving blocks are construction materials made from a mixture of cement, sand, aggregate, and water. Typically, paving blocks are molded in square or rectangular shapes and are used as surface coverings for roads, sidewalks, parking lots, and other public areas. One of the reasons why paving blocks are popular is because of their load-bearing ability, durability, and aesthetic appearance. This research aims to analyze paving blocks used in construction. Another objective of the research conducted was to analyze the opportunity of using added materials, namely recycled plastic and crumb rubber in making paving blocks, which aims to produce quality and sustainable products. In experimental research, the first step is to determine the variation in the composition of the additives used. Next, paving blocks are made through a dry mixing process until they are homogeneous, then molded using hexagonal molds and compacted manually. After that, the test objects undergo a curing process for 28 days before testing. Testing of paving blocks includes compressive strength and water absorption tests to determine the effect of adding additives on the quality and performance of the modified paving blocks. The results showed that the addition of plastic and crumb rubber can increase the strength of paving blocks and ensure flexibility and the product itself, reduce production costs and effective use of industrial waste.

Abstract

The construction of toll roads on soft soil frequently encounters geotechnical problems in the form of excessive ground settlement and low embankment stability, which may lead to structural failure if appropriate ground improvement measures are not implemented. Deep Soil Mixing (DSM) is a ground improvement technique in which in-situ soil is mixed with a binding agent to increase shear strength and reduce soil compressibility. This study aims to analyze the effectiveness of the DSM method in improving the stability of soft soil for toll road construction and to evaluate the influence of variations in column spacing and depth on soil deformation and safety factors. The study was conducted as a case study of the Probolinggo–Banyuwangi Toll Road Development Project, Package 2, at STA 16+550–STA 16+600, using analytical approaches and numerical modeling based on the finite element method with PLAXIS 2D software. Analyses were performed for conditions without ground improvement and with DSM improvement using two configurations, namely a column spacing of 1.5 m with a depth of 8 m and a column spacing of 1 m with a depth of 6 m. The results indicate that the application of the DSM method significantly increases the safety factor and reduces soft soil deformation, with a closer column spacing configuration demonstrating more optimal performance in enhancing embankment stability.
