Abstract

This study tackles the persistent environmental and economic complexities associated with conventional concrete manufacturing by establishing a novel sustainable production framework. This framework strategically integrates geospatial data on local aggregate reserves with key regional economic variables, focusing specifically on West Java, South Sumatra, and South Sulawesi as representative study areas in Indonesia. Leveraging Geographic Information System (GIS) technology and official statistics from the Geospatial Information Agency (BIG), alongside regional economic indices from the Central Statistics Agency (BPS), the investigation meticulously analyzed the spatial arrangement of high-quality aggregates, material price fluctuations, and crucial logistics expenditures. A multiple linear regression model was employed for quantitative analysis, which decisively revealed that aggregate pricing (=0.62, p < 0.001) and logistics expenses (=0.31, p < 0.05) are the predominant cost drivers in sustainable concrete production, whereas aggregate technical quality contributes a smaller, measurable influence (=0.09, p > 0.05). The exceptional coefficient of determination (R2=0.89) substantiates the model's predictive power and its practical utility for cost management and optimization within eco-friendly concrete systems. Ultimately, this research emphasizes the critical necessity of converging environmental, technical, and economic data for effective resource stewardship. It also proposes future scholarly endeavors should focus on integrating real-time monitoring and advanced digital supply chain technologies to further bolster the sustainability credentials of the domestic construction industry.

Abstract

Clay soil is a type of basic soil for a structure or construction that has characteristics, namely poor bearing capacity, this makes clay soil a material that is very lacking for construction work, so that improvements are needed by adding additives such as lightweight brick ash and Bentonite to the original soil. This study aims to obtain changes in the value of free compressive strength and shear strength with the addition of lightweight brick ash and Bentonite. With the addition of 10% bentonite, there was an increase of 12.19%, the free compressive strength value of the original soil was 0.812, increasing to 0.911 and the free compressive strength value continued to increase when lightweight brick ash was added with variations of 5%, 10%, 15% and, 20%. According to ASSHTO, the soil is classified as a type of clay soil that is included in group A-7-5, and according to USCS, the soil is included in the OH group "organic clay with moderate to high plasticity". The results of the compaction mechanical properties test increased in the optimum water content and dry volume weight, while the shear strength test obtained an increase in the cohesion value and internal friction angle. The highest cohesion value in the original soil of 10% light brick ash + 20% Bentonite is 0.6143 kg/cm3, and the highest friction angle value in the original soil of 10% light brick ash + 20% is 24.11. Meanwhile, in the compressive strength test, the highest Qu value was found in original soil with 10% light brick ash + 10% Bentonite, namely 1.260.

Abstract

Soil is the most important part to support a construction, one of which is clay soil which has a high moisture content so that the CBR of clay soil is low and causes a decrease in soil carrying capacity. This study aims to determine the effect of the addition of urea and fly ash fertilizers on the CBR value and permeability of clay soil. The percentages used in this study are Fly Ash 10% and Urea Fertilizer 10% and 20% plus variations in curing time, namely 7 and 14 days. According to AASHTO, soil is included in the A-7-5 category while according to USCS soil is included in the CH category. The maximum CBR value occurred at the addition of 10% Fly Ash + 20% Urea Fertilizer with 14 days of Curing with a CBR value of 23.89%.while the maximum Permeability Value occurred at the addition of 10% Fly Ash + 20% Urea Fertilizer with 14 days of Curing with a Coefficient value of 0.0151 cm/minute.

Abstract

Along with the development of technology and increasingly complex construction needs, the use of concrete is growing and becoming increasingly important in infrastructure development. One innovation to improve the quality of concrete is by adding additives or substitute materials to concrete. But concrete still has many weaknesses, especially in tensile and flexural strength, therefore the use of fibers such as nails or steel fibers in concrete is expected to be able to overcome these problems. In this study, a normal concrete compressive strength design of 25 MPa was used with the aim of the study to obtain the effect of nails on the tensile strength and flexural strength of concrete. In this study, the percentage of added nails was 2%, 4%, 6%, 8%, 10% of the weight of the concrete. This study shows that the use of nails in concrete causes an increase in tensile strength and flexural strength in nail variations of 2%, but the use of nails with variations of 4%, 6%, 8% and 10% decreases tensile and flexural strength. Increased tensile strength and flexural strength in nail variations of 2% with values of 3.06 Mpa and 5.67 Mpa. This shows that the greater the addition of nails, the tensile and flexural strength achieved decreases.

Abstract

Concrete is a very popular construction material and is widely used throughout the world. This is because concrete has several advantages, such as high strength, weather resistance, and relatively low cost, but forces the rate of cement production to increase which can cause carbon emissions and air pollution. Therefore, using silica fume as an alternative material as a cement reduction material by adding additional materials to strengthen the concrete mixture such as naphthalene. In this study, a normal concrete compressive strength design of 25 MPa was used with the aim of the study to obtain the effect of Cement Reduction Using Silica fume with Naphthalene Additives on the Compressive Strength and Flexural Strength of Concrete. The mixing method is carried out by partially replacing cement with silica fume by 10% and adding naphthalene additives of 0.2%, 0.4%, 0.6%, 0.8%, and 1%, respectively, by conducting concrete compressive and flexural strength tests. This study shows that the addition of Silica Fume as a partial replacement of cement by 10% with the addition of Naphthalene increases the compressive strength of concrete, and for a variation of 1% it gets the largest compressive strength value of 26.82 Mpa, and also increases the flexural strength value of concrete, and for a variation of 1% it gets the largest compressive strength value of 5.33 Mpa.

Abstract

Development in Indonesia continues to develop along with advances in technology, many types of soil have been discovered to improve the quality of clay soil, which is often done through various stabilization techniques. One method that has attracted attention is the addition of Trass and Firewood Ash. Trass, which is a volcanic-based additive, has pozzolanic properties which can improve its carrying capacity, firewood ash as a by-product of wood burning waste. The aim of this research is to find out how much influence the addition of trass and firewood ash has on clay soil. In this research, CBR and Permeability testing was carried out with substitution of 10% trass at variations of 10%, 15% and 20%. And add firewood ash as much as 5%, 10%, 15% and 20%. The CBR and Permeability values have increased successively. The CBR value of the original soil was 13.03%, the soil with a mixture of 5% firewood ash and 10% firewood ash had CBR values of 21.85 and 22.16, while the CBR value with a mixture of trass and firewood ash was 32.96%, 42.67 % and 53.32%. Meanwhile, the permeability value for the original soil is 0.0039%, for soil with variations of 5% firewood ash and 10% firewood ash the permeability value is 0.0048cm/m3 and 0.0057cm/m3, while the permeability value with a mixture of trass and firewood ash is 0 .0066cm/m3, 0.0078cm/m3 and 0.0086cm/m3

Abstract

Pile foundations are widely used in construction, particularly for structures on low-bearing capacity soils or heavy buildings. Driven and bored piles are the most common types. This study explores driven piles as an alternative to bored piles, focusing on foundation strength through bearing capacity comparison. The selected driven pile is a prestressed precast concrete pile, 1 meter in diameter and 14 meters deep. The method involves calculating bearing capacity using the Meyerhoff equation based on N-SPT data, along with analyzing pile reactions and displacement at the supports through displacement analysis. The calculation results show that the carrying capacity of piles with a diameter of 1 m and a depth of 14 m reaches 2861 kN, larger than a drilled pile with a diameter of 0.8 m and a depth of 21 m with a carrying capacity of 1895.1 kN. Based on these results, prestressed spun pile concrete piles were selected with a concrete quality of fc' 50 MPa, a diameter of 1 m, and a total length of 21 m. The selection of this alternative based on the results of the analysis is still within the safe limit so that the foundation is safe to use.
