Abstract

Road infrastructure has a function as one of the supporters of the development of an area. The Road infrastructure still used today is a flexible pavement composed of a mixture of asphalt and aggregate, which is heated and then compacted. Asphalt serves as a binder in the flexible pavement to maintain density and resist the weathering of aggregates caused by weather. It is an innovative additive used in concrete waste to replace rough aggregates. Adding LGA B50/30 in a base mixture is expected to be an alternative to improving the quality of the base mix and supporting the government in the use of domestic products. The study aims to determine how marshall is characterized if concrete waste is used in the AC-BC Ashburton mix as a substitute for rough aggregates and whether it meets the requirements of the Binna Marga Specification. The study was conducted experimentally with marshal characteristic parameters density, VIM (Void In Mix), VMA (Void In Mineral Aggregate), VFA (Void Filled with Asphalt), stability, and Marshall Quotient. (MQ). The Optimum Asphalt Rate used is 6.5%. The result is the density decreases with the addition of concrete waste levels, with the highest value at the 30% concrete waste level of 2,408 gr/cc. The increase in the VIM value with the addition of the concrete residue level has a higher value at a rate of 70% or 4.66%. The highest MQ is at a 50% concrete waste rate of 334.04 kg/mm. The study results show that waste concrete innovation materials can be used in Asbuton AC-BC mixtures with levels not exceeding 60%. Based on this research, concrete waste can be an alternative to natural aggregate substitutes.

Abstract

This research aims to conduct a feasibility study on the Meulaboh port dock in Aceh. The port dock is a key infrastructure in supporting shipping and trade activities in the region. With continued economic growth and changing trade patterns, it is important to evaluate the feasibility and need to upgrade the Meulaboh port dock. The port dock feasibility study involves reviewing several analytical aspects, including technical, economic, environmental, and social aspects. However, in this research, the researcher only reviewed the technical aspects. Researchers will evaluate the physical condition and capacity of the pier so that barges can dock safely. The research methodology involved field surveys, secondary data analysis, and interviews with relevant stakeholders. It is hoped that the results of this research can provide clear guidance for decision-making regarding investment and development of the Meulaboh port pier.The research entitled Feasibility Study of the Meulaboh-Aceh Port Pier resulted in the conclusion that the pier can be berthed by barges measuring 270 feet. It is hoped that the results of this research can also be a basis for intelligent decision-making in efforts to improve and develop this important port infrastructure. The results of this research indicate that there has been damage to the jetty pier structure and significant corrosion to the breasting dolphin structure. The deformation due to service loads is very large in the damaged area of the pier jetty structure so it will definitely endanger users. Recommendations for this pier to continue functioning as public infrastructure require repairs.

Abstract

Clay soil is a type of soil that has problems because it has high plasticity, a low carrying capacity, and is prone to settlement. This soil condition can be found in the Hanging Tramble, Pangkalpinang City. This study aims to determine the effect of FGD waste gypsum on clay soils, the maximum value of soil shear strength, and the minimum value of soil consolidation settlement. The stabilizing agent used in this study was Flue Gas Desulfurization ( FGD) waste gypsum with a mixture of 10%, 15%, and 20% FGD waste gypsum from the dry weight of the soil., for a total of 39 samples of the test object. Testing in this research uses Indonesian National Standards (SNI).The test results obtained the maximum value of the shear strength of the soil in the FGD waste variations of gypsum at 15%, which is 115.243 kN/m2, and in the 20% FGD gypsum waste mixture, the value of the shear strength of the soil decreased by 79.634 kN/m2. The minimum value for consolidation settlement was obtained from FGD waste variations (gypsum 20%), which is 0.683 cm. The minimum value obtained for consolidation settlement is influenced by the calcium content in the FGD waste gypsum, which can bind soil minerals so as to increase soil strength. It can be concluded that the maximum soil shear strength value occurs in the 15% FGD waste mixed sample variation gypsum, while the minimum soil consolidation settlement value is in the 20% mixed FGD waste mixture gypsum.

Abstract

Cantilever beam structures are part of civil building structures that are efficient in supporting loads without requiring additional structures. The reasons for using cantilever beams are that they can reduce weight compared to prismatic beams so that costs are reduced, architecturally they provide visual beauty and are aesthetically attractive, they can increase structural rigidity, they can reduce deformation to maintain structural stability and performance and they can produce innovative designs according to needs. The research method used is a quantitative research method using material data, geometry and cross-section of structural components. Model and analysis using SAP2000 software. In this research, 5 models have been made consisting of 1 reinforced concrete prismatic cantilever beam model with a ratio of end beam height (h1) and base beam height (h2) h1/h2 = 1/1 and 4 models (model 2, model 3, model 4, model 5) reinforced concrete nonprismatic cantilever beam with variations in the nonprismatic ratio of end beam height and base beam height with ratios h1/h2 respectively 1/2, 1/3, 1/4, 1/5. The dimensions of the beam are 450 mm wide and 1000 mm high with a beam length of 4000 mm. The beam is modeled as a shell element with rectangular and triangular element models. The position of the base of the cantilever structure is fully clamped. Based on the results of the analysis, it can be concluded that decreasing the height ratio (h1/h2) of the reinforced concrete non-prismatic cantilever beam or reducing the concrete volume for each model causes an increase in deflection and a decrease in the maximum principal stress (Smax) for the reinforced concrete prismatic cantilever beam model.

Abstract

The increase in building and infrastructure development in Indonesia demands effectiveness and efficiency in construction projects, particularly in the selection and placement of heavy equipment such as tower cranes. This study focuses on optimizing the placement of a tower crane in the construction project of the Graduate Building of Universitas Riau, planned to have 6 floors with a height of 31.45 meters. The main issues include delays in structural progress and the tower crane being positioned close to the maximum jib reach, which decreases lifting speed and increases cycle time, ultimately raising operational costs. The research aims to find a placement that maximizes productivity and minimizes operational costs. The methods employed include direct observation and interviews. Observations were conducted on 20 columns at elevation 13.45 meters on the 3rd floor to determine the tower crane cycle time. Data analysis compared cycle times between the existing placement and two alternative placements. The study results indicate that the existing placement requires 598.195 hours with operational costs of Rp1,402,373,077.80, while alternative 7 requires 590.637 hours costing Rp1,389,917,824.27, and alternative 9 requires 606.393 hours costing Rp1,415,882,093.32. The time and cost difference between alternative 7 and the existing setup is 7.558 hours faster and Rp12,455,253.54 cheaper. Hence, the optimal position for the tower crane is alternative 7 at coordinates 764722.537; 53537.493. This placement demonstrates that a shorter distance between the tower crane and the supply point enhances productivity and reduces operational costs.
