Abstract

Clean water supply is one of the crucial aspects that must be considered in every region. PDAM is responsible for meeting clean water needs by considering quality, quantity, and continuity. A distribution network that does not meet the standards will hinder fulfilling the community's clean water needs. Tools such as E-PANET are needed to analyze and optimize the water distribution system, which can be used in the design, hydraulic model calibration, residual chlorine analysis, and customer evaluation. This research was conducted in Adi Mas Giri Banyuwangi Housing, Banyuwangi Regency, using a quantitative analysis using E-PANET 2.0 and GIS software. The results showed that the clean water demand in Adimas Giri Banyuwangi Housing was 0,2784 liters/second. Meanwhile, the analysis results using E-PANET 2.0 show that the clean water distribution network in the area has not functioned optimally. Therefore, improvement efforts are needed, such as replacing large-diameter pipes that do not flow with smaller ones, adjusting the pressure in the system, and identifying potential bottlenecks in the network. With this optimization, clean water distribution in Adi Mas Giri Housing is expected to be more efficient and equitable.

Abstract

The production of portland cement generates carbon dioxide emissions, which contribute to environmental degradation. To address this issue, researchers have explored the use of coal waste, such as fly ash, as a partial replacement for cement. This research investigates the potential of fly ash as a substitute in the production of geopolymer concrete. The research follows an experimental approach involving the fabrication of test specimens to evaluate the concrete's mechanical properties. The process encompasses material analysis, specimen preparation, curing, and testing for volume weight, compressive strength, split tensile strength, and elasticity modulus. The findings reveal that the volume weight values range between 2.260,000 kg/m ³ and 2.336,395 kg/m ³, while compressive strength varies from 10,152 MPa to 16,994 MPa. Additionally, the split tensile strength falls within 1,415 MPa to 1,556 MPa, and the elasticity modulus spans from 2.727,352 MPa to 3.325,204 MPa. The results emphasize the significant influence of temperature variations on the mechanical performance of geopolymer concrete, with 60 °C identified as the optimal curing temperature for achieving the highest compressive strength, split tensile strength, and elasticity modulus.

Abstract

The lateral bearing capacity of piles is a crucial factor in foundation design, particularly under lateral loads. This study analyzes the lateral bearing capacity of hydraulic jacked-in piles using the Broms method and interprets loading test results with the Chin and Mazurkiewicz methods. Additionally, numerical analysis of lateral deflection was conducted using the p-y method in LPile and the Finite Element Method (FEM) in PLAXIS 3D to assess compatibility with field test results. The results indicate that the lateral bearing capacity is 16,20 tons using the Broms method, 18,76 tons with the Chin method, and 16,50 tons with the Mazurkiewicz method. The lateral deflection at 200% load was 11,82 mm from field tests, 14,69 mm from LPile, 12,25 mm from PLAXIS 3D (Mohr-Coulomb), and 11,91 mm from PLAXIS 3D (HS Small). The HS Small model yielded the most accurate prediction, closely matching field test results. This research highlights the importance of numerical modeling in predicting lateral pile behavior and provides valuable insights for foundation design under lateral loads.

Abstract

The T. Nyak Makam Canal Bridge in Santan, Banda Aceh, serves as a vital transportation link, spanning 135 meters in length and 24,6 meters in width. This study presents a comprehensive analysis of the pile foundation bearing capacity, utilizing Standard Penetration Test (SPT) data to evaluate the middle pillar"™s structural performance. The analysis adheres to established engineering standards, including SNI 03-1726-2002, SII 0136-80, SNI 03-6747-2002, and PPPJJR (1987). The bearing capacity was assessed using multiple methodologies: Meyerhof"™s method (169.99 tons), Briaud et al."™s method (280,52 tons), and the material strength method (349,561 tons), yielding an average bearing capacity of 266,69 tons. Given the total structural load of 36.778 tons, the foundation required 228 piles to ensure optimal load distribution and stability. Pile group settlement analysis via the Meyerhof method indicated a displacement of 0,1328 m, while stability assessments resulted in ΣVi = 37.169,145 tons, ΣHi = 4.191,265 tons, and ΣMi = 838,669 t.m. The foundation consists of reinforced concrete piles with a diameter of 0,5 meters and a length of 26 meters, strategically arranged in 38 columns and 6 rows to maximize structural integrity. The findings confirm that the pile foundation exhibits high stability and meets all safety requirements, ensuring its suitability for long-term bridge performance.

Abstract

Geopolymer concrete is a form of concrete where the traditional Portland cement binder is substituted with alternative materials rich in silica and aluminum. Cement production involves a high-temperature combustion process, reaching 1.500 °C, which produces large amounts of carbon dioxide (COâ‚‚) emissions, roughly equivalent to the amount of cement produced. Due to the significant environmental impact of traditional cement production, there has been a growing emphasis on developing geopolymer concrete that uses fly ash as an alternative binder in concrete mixtures. This study adopts an experimental approach to fabricate geopolymer concrete specimens incorporating fly ash. The study involves testing to assess both the physical and mechanical properties. The findings indicated a slump range of 16-28 cm, an average density ranging from 2.274,501 Kg/m ³ to 2.322,177 Kg/m ³, a 28-day compressive strength between 11,247 MPa and 15,915 MPa, split tensile strength varying from 1,179 MPa to 1,721 MPa, and elasticity modulus between 2.003,573 MPa and 3.417,811 MPa. The optimal variation was achieved by adding 0% water. Thus, geopolymer concrete incorporating fly ash holds considerable promise as an environmentally sustainable substitute for traditional cement-based binders.

Abstract

Roads are vital infrastructure that plays a role in supporting economic growth, the agricultural sector, and regional development by improving accessibility and smooth transportation. However, high traffic intensity and environmental factors can cause road quality degradation, impacting user safety and comfort. Kubu Raya Regency still faces road deterioration problems, one of which is on the Jalan Rasau Jaya - Sungai Bulan section in Rasau Jaya District. This research aims to identify the types of road deterioration, evaluate the pavement condition using the Surface Distress Index (SDI) and Pavement Condition Index (PCI) methods, and provide recommendations for improvement. The analysis showed that the road experienced various types of deterioration, including potholes, slippage cracks, ravelling, longitudinal cracking, edge cracking, transverse cracking, rutting, and alligator cracking. The SDI values at the first, second, and third kilometres were 237,5, 235, and 237,5, respectively, indicating severe deterioration. Meanwhile, the PCI values indicate poor to very poor conditions, with values of 29,91, 13,32, and 21,58. Based on the evaluation results, reconstruction is recommended for the entire segment. Both methods provide similar recommendations, but the PCI method is superior due to its more detailed classification and ability to categorize deterioration by severity and type.

Abstract

Geopolymer concrete is a sustainable alternative that replaces Portland Cement (PC) with fly ash. This research aims to analyze the mechanical properties of geopolymer concrete with variations in NaOH solution aging. An experimental method was applied through a series of tests, including slump, compressive strength, split tensile strength, and modulus of elasticity. The results indicate that the slump value ranges from 9,5 cm to 15,5 cm. The bulk density of geopolymer concrete varies between 2.313,052 Kg/m ³ and 2.387,324 Kg/m ³. The maximum compressive strength at 28 days was achieved after a 24-hour NaOH curing period, reaching 15,915 MPa, whereas the minimum strength of 10,186 MPa was observed with no curing time. The highest split tensile strength was observed at 24 hours (1,556 MPa), whereas the lowest occurred at 0 hours (1,085 MPa). Using the Chord Modulus method, the modulus of elasticity reached its highest value at 24 hours (3.625,261 MPa) and its lowest at 48 hours (2.152,499 MPa). Thus, this research concludes that a 24-hour NaOH curing period results in geopolymer concrete with optimal compressive strength and mechanical properties.

Abstract

Geopolymer concrete is an innovative construction material developed as an alternative to Portland cement. First introduced by Davidovits in 1978, geopolymer exhibits a chemical composition similar to zeolite but with an amorphous microstructure. One of its most significant advantages is its ability to reduce carbon dioxide emissions by approximately 80% compared to conventional concrete, making it a promising solution for mitigating the environmental impact of the cement industry. This study explores the utilization of coal-fired power plant waste to develop geopolymer concrete with varying heating durations, aiming to create a more environmentally friendly alternative that reduces pollution and lowers COâ‚‚ emissions from cement production. The experimental process involved producing test specimens using fly ash, NaOH, Naâ‚‚SiO₃, fine aggregates, and coarse aggregates, followed by mechanical property evaluations, including compressive strength, splitting tensile strength, and elastic modulus tests. The results demonstrated an average density ranging from 2,238.780 kg/m ³ to 2,323.662 kg/m ³, an average 28-day compressive strength between 15.279 MPa and 16.977 MPa, an average splitting tensile strength ranging from 1.320 MPa to 1.627 MPa, and an average elastic modulus (Chord Modulus method) between 2,838.251 MPa and 3,631.342 MPa. The optimal heating duration was identified as 24 hours, producing the highest 28-day compressive strength of 16.977 MPa. These findings confirm that fly ash is a viable substitute for cement in construction applications, offering a sustainable and eco-friendly alternative to traditional concrete.
