Abstract

Material delays are a significant challenge in completing construction projects, closely tied to the understanding of material supply flow. As a result, a risk weight analysis is essential, considering both internal factors (such as supply, control, processes, and demand) and external factors (such as disasters). This study began with a literature review to compile a list of potential risks, followed by data collection through a questionnaire administered to 50 experts in construction material procurement. The risk analysis was then conducted using both the Severity Index and Monte Carlo methods. The results showed average risk differences between the two methods: supply side (16.40% vs. 16.76%), control risk (16.28% vs. 11.53%), process risk (11% vs. 11.20%), demand risk (16.10% vs. 13.87%), and disaster risk (13.78% vs. 13.41%). The highest risk identified was in the supply side, specifically the extended waiting times due to staggered material deliveries, while the lowest risk was related to the process of ordering materials, where issues arise from the need for reordering based on inaccurate quantity information.

Abstract

Erosion is one of the exogenic processes that commonly occur around river dynamics. Intensive erosion occurs at the riverbank area, which has the potential to cause the slope on that side to collapse. Therefore, a groyne-type structure is required to prevent this from happening. A groyne-type structure is planned to reduce the impact of erosion in the Pelangai River with embankment. This research aims to determine the stability of the groyne with embankment design using Plaxis 2D software. Plaxis 2D modeling uses soil input parameters based on CPT, SPT, and groyne structure with approximation parameters. The modeling results show that with the addition of groyne, embankment and traffic load, the safety number drops from 1.906 to 1.241. This figure does not meet the safe number limit according to SNI Geotechnical 8460 of 2017, which requires a minimum safe number of 1.25. In addition, the addition of groyne, embankment, and traffic load resulted in soil settlement of up to 6.3 cm, which is still considered safe.

Abstract

This research focuses on the design of earthquake-resistant houses in West Sumatra Province to improve the structural quality of residential buildings. Significant damage to houses caused by previous earthquakes poses a serious threat, especially as it can hinder evacuation processes during disasters. Ensuring individual safety is a top priority in evacuation efforts, making it crucial to build earthquake-safe homes, whether through new construction or renovation, to minimize the risk of casualties. The study employs a quantitative approach guided by the earthquake-resistant house requirements handbook developed by JICA and the Ministry of Public Works. The result is an alternative DED design for a Type 45 house suitable for West Sumatra. This single-story house is designed on hard soil with a structure that meets earthquake standards. The analysis results show the structural specifications as follows: the foundation uses stone with a bottom dimension of 80 cm, a top dimension of 40 cm, and a height of 80 cm; BS beams measure 15 cm x 30 cm; RB beams 15 cm x 20 cm; and columns 20 cm x 20 cm. The average Safety Factor (SF) values are BS beams 1.04, RB beams 1.3, columns > 3, and stone foundation 3, indicating that the planned sections meet the requirements for earthquake-resistant houses. This study aims to contribute to disaster risk mitigation and serve as a guide for communities in constructing earthquake-resistant homes, especially in the West Sumatra region.

Abstract

Building constructions found in Indonesia generally use concrete as the main structural material. This research aims to analyze the use of ground granulated blast furnace slag (GGBFS) as a cement substitute in concrete mixtures using the Analysis of Variance method (Anova) and the Tukey Method. The GGBFS levels used are 0%, 25%, 30%, 35%, 40% and 45% as cement substitute. The average compressive strength values ​​obtained for each sample were 25.08 MPa, 25.1 MPa, 25.7 MPa, 25.9 MPa, 26.4 MPa, 27.7 MPa and 26.2 respectively. MPa. The compressive strength value continues to increase with the highest compressive strength value at 40% and decreasing again at 45%. The use of ggbfs requires an activator to accelerate the mechanical properties of ggbfs itself. The activator used is NaOH with a concentration of 4 Mol.

Abstract

Coconut shell waste is one type of agricultural waste that is often underutilized, despite its potential as an alternative material in concrete construction. This study aims to examine the effect of using coconut shells as coarse aggregate in concrete, focusing on the compressive strength of the concrete. Standard concrete with varying coconut shell proportions of 0%, 2%, 4%, 6%, and 8% was tested to observe differences in compressive strength. The results showed that as the percentage of coconut shell in the concrete mix increased, the compressive strength tended to decrease. Concrete with coconut shell proportions of 2%, 4%, 6%, and 8% exhibited average compressive strengths of 16.416 MPa, 16.327 MPa, 14.817 MPa, and 13.779 MPa, respectively, compared to normal concrete with an average compressive strength of 20.008 MPa. This decrease in compressive strength is attributed to the physical properties of coconut shells, which have lower density compared to conventional aggregates. Nevertheless, the use of coconut shells as coarse aggregate offers environmental and economic benefits, such as reducing waste and dependence on limited natural resources.

Abstract

The availability of clean water is very important for improving public health. Clean water sources can come from the ground, rivers, dug wells, and so on. The Pangkalarang community also really needs clean water. Currently, they only use dug well water that does not meet health requirements. The quality of clean water in this area is affected by seawater intrusion that pollutes groundwater. Pangkalarang has a surface water source in the form of Rangkui River water whose quality must be known if it is to be used as clean water. So researchers consider it necessary to conduct laboratory tests on river water samples. The parameters tested were pH (5.83) so that the pH of the water is categorized as an acidic liquid because the pH value is less than 7), COD (the highest value is 39.8 mg/L while the standard value is 10 mg/L), BOD (the highest value is 4.52 mg/L while the standard value is 2 mg/L), heavy metal content Zn (value <0.0377 mg/L and while the standard value is 0.01 mg/L), and Eschericia Coli bacteria content (the highest value is 350 MPN/100 ml while the standard value is 0 MPN/100 ml) according to PP Number 22 of 2021 concerning the Implementation of Environmental Protection and Management. Based on laboratory tests, Rangkui River water does not meet health requirements. Therefore, researchers do not recommend the river water as a source of clean water.

Abstract

Slopes are open land surfaces that form an angle and therefore their stability and safety factors need to be considered. This research aims to analyze the stability of sand slopes using the Bishop Simplified method in Hyrcan 2.0 software with the addition of calcite (CaCO3) as a reinforcement method. Sand slopes have low stability due to low cohesion and lack of interaction between particles, which is exacerbated by the influence of groundwater. The addition of CaCO3 in various concentrations (0%, 10%, and 20%) was applied to improve the shear strength parameters of the sand slope. The simulation model includes six material variations with slope geometric configurations that reflect field conditions. The simulation results showed that the slope with 20% CaCO3 concentration had the highest factor of safety (FOS) of 1.05, compared to 0.73 in the model without reinforcement. Vertically shifting the landslide center point affects the length of the slide plane and the FOS value, where increasing the CaCO3 concentration contributes significantly to improving the slope stability. The relationship between the vertical location of the landslide center and FOS was analyzed using linear regression, which showed a negative relationship between the two. This study concludes that the addition of CaCO3 effectively improves the stability of sand slopes, with FOS approaching safe values although the FOS value in the best model is still categorized as unsafe.

Abstract

This study assesses the financial feasibility of a privately financed infrastructure project under a Build-Operate-Transfer (BOT) scheme with a total investment of USD 76 million. The investment is distributed over a three-year construction phase, followed by a 30- to 60-year operation period generating annual net profits of USD 8.64 million. Key financial metrics including Net Present Value (NPV) and Internal Rate of Return (IRR) are utilized to evaluate the project. The results indicate a negative NPV of approximately USD -14.85 million for a 30-year operation, suggesting the project is not viable under a conservative time horizon. However, extending the operation to 60 years yields a positive NPV of USD +23.8 million and an estimated IRR of 11.7%, surpassing the assumed discount rate of 10%. These findings highlight the importance of operational duration in BOT projects and suggest that long-term operation is essential to achieve financial sustainability. Recommendations include extending the concession period and optimizing cost structures to enhance investment attractiveness.

Abstract

Candlenut shells are an organic waste that can be used as a mixed aggregate in making lightweight concrete to reduce environmental pollution. This research aims to analyze the compressive strength performance and the effect of changes in the water absorption capacity of paving blocks made from plastic waste mixed with candlenut shells as a substitute for fine aggregate. Using experimental methods according to the SNI-03-2834-2000 standard, this research was carried out at the Structure and Materials Laboratory of the Muhammadiyah University of Parepare with 12 paving block samples. The results showed that after 3 days, the addition of candlenut shells of 0%, 10%, 15%, and 25% increased the compressive strength of paving blocks of 4,450 MPa, 4,633 MPa, 4,917 MPa, and 5,000 MPa respectively, while the absorption capacity water increases to 1.1%, 1.5%, 1.6%, and 2.0% at the age of treatment The same. The combination of candlenut shell waste with plastic waste has been proven to increase the compressive strength performance of paving blocks, with optimal results obtained by adding 25% candlenut shells. This shows that candlenut shell waste has the potential to be an effective component in paving block mixtures made from plastic waste, while providing dual benefits in reducing waste and improving material quality, thereby contributing to environmental sustainability and advances in concrete technology.
