Abstract

Mortar mixture is an important element in civil/construction work. As a binding agent, mortar mixtures are widely used in various types of work with different strength levels according to their needs. Many sand raw materials are often used but do not meet the material requirements, either grain gradation or other requirements. In this research, a compressive strength test was carried out using fine sand with the addition of stone ash, to test how much strength was achieved with varying percentages of additional stone ash. The manufacture of test specimens for this mortar mixture refers to SNI 03-6882-2002. Testing was carried out at 7 days, 14 days and 28 days. With additional variations of 0%, 20%, 40% and 60% stone ash. The results of this research are mortar mixtures with the addition of 20% stone ash will increase the compressive strength from 4.74 MPa without the addition of stone ash to 7.13 MPa, tending to decrease at an additional 40% the compressive strength is 6.96 MPa and at an additional 60% the strength is obtained. press 5.74Mpa. The simple regression equation for the relationship between the addition of the percentage of stone ash (variable x) and the compressive strength value (variable y) is y = -22.578x2 + 14.97x + 4.8122 with the coefficient of determination R2 = 0.97 (very strong).

Abstract

High-strength concrete is a crucial construction material in modern infrastructure development. It involves replacing some conventional raw materials with environmentally friendly alternatives to enhance concrete quality. Rice husk ash (RHA) is an agricultural waste that contains natural pozzolanic materials capable of improving the mechanical properties and strength of concrete. The use of rice husk ash (RHA) in high-strength concrete mixtures has the potential to reduce cement consumption and enhance crack resistance. The aim of this research is to investigate the effect of substituting cement with rice husk ash and the addition of superplasticizer on the flexural strength of concrete. The target concrete strength is 4.50 MPa, with rice husk ash substitution rates of 5%, 10%, and 15% of the cement weight. This study found the flexural strength of the concrete at 28 days to be 4.71 MPa for the 5% substitution, and 3.79 MPa for both the 10% and 15% substitutions.

Abstract

So far, there have been many industrial waste materials such as onyx sand, iron lathe fibers that have not been utilized optimally. One ofthe industrial waste that has not been used optimally is glass waste This study aims to determine the effect of the addition of glass powder on the compressive strength of paving blocks and polynomial regression relationships between variations in glass powder and compressive strength of paving blocks. The method used in this study was to conduct research in the Laboratory of the Faculty of Engineering, University of Muhammadiyah Palangkaraya with variations in the addition of glass powder 0%, 2%, 4% and 6%. Overall the compressive strength of paving blocks fluctuates with the addition of glass powder instead of partial volume. Concrete compressive strength with a variation of 0% is 33.14 kg / cm2, variation of 2% is 22.65 kg / cm2, variation of 4% is 22.92 kg / cm2 and variation of 6% is 26.38 kg / cm2. Where the compressive strength of paving increases with the addition of glass powder by 6% with an increase ratio of 0.79 from the condition of 0%. This shows that the addition of glass powder at a variation of 6% only reduces the compressive strength of 21% from a variation of 0%. Polynomial regression equation relationship between the addition of glass powder with compressive strength of paving blocks is Y =32.760953 - 623.05279. X + 8717,332985 X 2

Abstract

The Nusantara Capital City (IKN) development project is one of the strategic megaprojects in Indonesia with the aim of moving the center of government to East Kalimantan. The megaproject faces a number of significant challenges, including delays in physical progress, budget constraints, constraints in land acquisition, and complex technical risks. This study aims to analyze the challenges and risk mitigation strategies implemented in the IKN project through a qualitative approach based on progress reports until September 2024. With thematic analysis using the NVivo tool, three main themes in risk mitigation were found, namely flexible financial management, the use of Building Information Modeling (BIM) technology, and a cross-sector collaborative approach. The use of BIM has proven to be effective in detecting design clash detection, which reduces technical risks in the field. In addition, the involvement of local governments and local communities in the land acquisition process accelerates negotiations and reduces the potential for social conflict. The results of this study show that cross-sector collaboration, technology integration, and adaptive budget management play an important role in ensuring the smooth running of large-scale projects. This study is expected to contribute to the development of risk management strategies in Indonesian infrastructure projects.

Abstract

Sukabangun II Street in Palembang City is an area with a fairly high population density where the quantity of activities is quite high using vehicles on the road. The position of this road in Palembang City which is a traffic activity for the community's economy will affect street activities, especially at the intersection of this road. Traffic jams often occur due to narrowing of the road and slowing of vehicle flow along the intersection on Jalan R.A Abusamah and the direction of Jalan Beringin. This results in obstacles to traffic for people passing through Jalan Sukabangun II. In this study, an evaluation of the performance of the Sukabangun II road section in Palembang City was carried out. The method used is the PKJI 2023 method and is interpreted in 3-dimensional visualization using the PTV VISSIM Ver. 2021 microsimulation application. The results of the study showed a capacity value of 1,904 pcu units per hour, and a traffic flow value (Q) of 1160.8 pcu units per hour, so that the degree of saturation (DJ) was obtained as 0.61. This conclusion shows that the Sukabangun 2 road section in Palembang City is included in the category of roads with service level F.

Abstract

Most of the railway lines in Indonesia use a ballasted track system, including the Jember–Kalisat line in Operational Area IX Jember which is the location of this research. The rail structure consists of a superstructure (rails, tethers, sleepers) and a substructure (ballast layer, sub-ballast, subgrade), which must meet technical specifications according to PM 60 of 2012. The ballast layer is the initial layer that receives load distribution from the upper structure, so it requires routine maintenance to maintain stability. This research aims to estimate the decline in the ballast layer due to annual loads using a quantitative approach. The calculation results show that the annual tonnage on the Jember–Kalisat segment is 17,328,960 tons/year, which is in accordance with class II route specifications. Field measurements at five sample points showed that the ballast thickness did not meet the standard, namely 30 cm, so it was estimated that there would be a greater decrease compared to standard conditions. The largest estimated decrease occurred at KM 202+200 to KM 202+300, with a decrease of 4.06 cm per year upstream and 3.36 cm per year downstream. This calculation also produces an estimated graph of ballast layer reduction based on annual tonnage. It is hoped that this research can provide important recommendations regarding ballast layer maintenance to maintain railway track stability.

Abstract

Road safety is a crucial aspect that must be prioritized when planning a transportation system. In 2023, Magelang Regency recorded 1,016 accident cases, resulting in 154 fatalities. One of the contributing factors to these accidents is road conditions. The Magelang-Purworejo Provincial Road faces significant challenges, particularly due to its steep and lengthy descents, which are a major cause of accidents. Drivers, especially those operating heavy-loaded vehicles, often struggle to control their speed on sharp declines, especially during slippery or rainy conditions. This study aims to identify potential hazards on the Magelang-Purworejo Provincial Road to reduce the risk of accidents and fatalities caused by road hazards. Using the Hazard Identification Risk Assessment (HIRA) method, the safety inspection analysis for the Magelang-Purworejo Road—a primary collector road with a provincial status and a 2/2 UD type—revealed several key hazards, including uneven shoulder height, road damage, obstructed traffic signs, and limited visibility. Based on the risk assessment, 18% of hazards are categorized as low level, 76% as moderate, and 6% as high, with major consequences accounting for 24%, and the highest likelihood of accidents reaching 41%. Improvement recommendations have been proposed to mitigate these risks and enhance the safety of road users.

Abstract

Clay soil has high plasticity and low shear strength characteristics, making it a challenge in construction projects, especially in areas with high water content, such as Bereng Bengkel District, Palangkaraya City. To address this issue, polymers and biopolymers have been used as stabilization materials to enhance the shear strength of the soil. This study aims to evaluate the effect of adding polymers and biopolymers on the mechanical parameters of clay soil, particularly cohesion (CC) and internal friction angle (ϕ). Laboratory experiments were conducted following SNI 2825:2015 standards for direct shear testing. Clay soil samples were collected from Bereng Bengkel and mixed with polymer (polyacrylamide) and biopolymer (xanthan gum) at concentrations of 0.5%, 1.0%, 1.5%, and 2.0%. Shear strength parameters were analyzed to determine the effectiveness of each stabilization material, with the optimal concentration determined based on maximum cohesion and internal friction angle values. The results showed that the addition of polymer could increase cohesion by up to 70% and the internal friction angle by up to 130% at concentrations of 1.0% to 1.5%, while biopolymers could increase cohesion by up to 39% and the internal friction angle by up to 313% at concentrations of 1.0% to 2%, compared to the initial values. These findings indicate that soil stabilization with polymers and biopolymers significantly improves the shear strength of Bereng Bengkel soil. The study concludes that the optimal combination of stabilization materials can significantly enhance the mechanical properties of clay soil and opens opportunities for further research with other additive materials such as lime or cement.

Abstract

The segment of Jalan Yos Sudarso is designated as a shopping area. The largest shopping center on Jalan Yos Sudarso is Lippo Plaza. Activities at Lippo Plaza are frequented by many residents of Palangka Raya City. This condition affects the level of traffic congestion caused by the significant movement of vehicles to and from Lippo Plaza, which includes traffic volume, side obstacles, and vehicle speed. This study aims to discuss the impact of activities at the Lippo Plaza shopping center on the performance of the road segment on Yos Sudarso Street in Palangka Raya City, including the average daily traffic volume, average side friction, instantaneous vehicle speed, and vehicle maneuvering time at U-turns using the Indonesian Road Capacity Guidelines 2023. From the research results, the peak traffic volume was obtained at 1,346.30 smp/hour in Direction A-A, and 1,503.10 smp/hour in Direction B-B. The peak side friction obtained was 1,852.80 incidents/hour in Direction A-A with a classification of "Very High" and 410.70 incidents/hour in Direction B-B with a classification of "Moderate." The saturation degree values obtained were 0.48 in Direction A-A and 0.49 in Direction B-B, with the service level classification for both directions being "C."

Abstract

Traffic Impact Analysis (Andalalin) is basically an analysis of the influence of land use development on the surrounding traffic flow system, which is caused by the generation of new traffic, diverted traffic, and by vehicles entering and leaving the development land. The Kirana Garden Residence housing development plan will have an impact on the smoothness of traffic around it, especially the performance of the nearest roads in the development area. Therefore, there is a need for a study to analyze the impacts resulting from the Kirana Garden Residence housing development plan. The aim of this research is to identify the performance of sections and intersections that are estimated to be affected by the Kirana Garden Residence housing construction activities, then formulate efforts to deal with the impact caused by the Kirana Garden Residence housing construction activities on the surrounding traffic. The research method used is the Indonesian Road Capacity Guidelines 2023 (PKJI 2023) approach, with the results namely the value of the degree of saturation of the surrounding road sections and intersections during existing conditions before construction and during operational conditions after the construction of the Kirana Garden Residence housing complex. The results of the research show that there is a decrease in road performance after the Kirana Garden Residence housing development plan, so it is necessary to take action to minimize the impact of traffic that will occur, especially during the Kirana Garden Residence housing construction activities.
