Abstract

In construction projects, contract types play a crucial role in determining project success. This study examines the implementation of Lump Sum and Unit Price contracts in a fence construction project undertaken by PT. United Tractors Tbk in Jakarta. The research identifies the challenges and discrepancies arising from the use of Lump Sum contracts, especially when complete documentation is not available during the bidding process. A descriptive quantitative method is employed to analyze field data, interviews, and surveys with relevant stakeholders. The findings indicate that the Lump Sum contract led to significant additional work claims amounting to 16% of the initial contract value due to incomplete initial documentation and design changes during execution. The study also compares the Lump Sum contract with a hypothetical Unit Price contract scenario, revealing a potential cost deviation of 22.19%. The evaluation suggests that the Lump Sum contract was less suitable for this project, recommending the Unit Price contract as a more flexible alternative to accommodate changes and uncertainties in construction projects.

Abstract

Transport mode choice is a method for determining the choice of transportation mode for individuals on their way to a destination, which is influenced by several factors. This research focuses on the selection of transportation modes between conventional taxis and online taxis at the Purabaya Terminal in Sidoarjo. This study determined the characteristics of mode users, the factors influencing mode selection, the mode selection probability model, and the model sensitivity when a change occurred in each trip attribute. The data collection process was carried out by distributing questionnaires with the revealed preference technique to bus passengers who got off at Purabaya Sidoarjo Terminal. transport mode choice model data analysis used the binomial logit model and regression analysis. The results of multiple regression analysis to see the variables that influence the choice of mode found that the variables influencing the choice of mode in this study included gender, age, income, travel destination, estimated time, cost estimation, travel purpose, and mode background. The analysis using the binomial logit model revealed that at a waiting time of 5 minutes, the probability of choosing a conventional taxi was 1.40%, while the probability of choosing an online taxi was 98.64%. When the waiting time was 0 minutes, the probability of choosing a conventional taxi was 5.11%, while the probability of choosing an online taxi was 94.89%. In order for the chances of choosing a conventional taxi to be above 50%, the conventional taxi mode must reduce the waiting time by about 10 minutes so that a conventional taxi is chosen.

Abstract

The current concrete mix design is still based on the guidelines in SNI 03-2834-2000 which refers to Departement of Environment (DoE), Building Research Establishment, Britain and SNI 7656: 2012 which refers toAmerican Concrete Institute (ACI) 211.1-91. This study analyzes the differences between the standards SNI 7656:2012 and SNI 03-2834-2000 in designing concrete mixtures with a target compressive strength of 20 MPa. The analysis results show that SNI 7656:2012 uses less coarse aggregate, cement, and water, specifically 4.39%, 23.07%, and 16.35% less, respectively, but uses 41.75% more fine aggregate compared to SNI 03-2834-2000. The concrete designed using SNI 03-2834-2000 resulted in higher average compressive strength by 25.82%, higher tensile splitting strength by 46.27%, and higher flexural strength by 18.93%. However, the rate of strength development at 14 days was faster for concrete designed with SNI 7656:2012, with increases of 14.37% in compressive strength, 13.53% in tensile splitting strength, and 9.69% in flexural strength. Additionally, the water-cement ratio (WCR) and the proportion of aggregate mixtures were found to have a significant impact on concrete strength; a lower WCR and a higher proportion of coarse aggregate tend to increase concrete strength.

Abstract

The International Roughness Index (IRI) is a parameter used to determine the level of unevenness of a road surface in units of m/km. This parameter measures the level of unevenness of the road surface presented in a scale of values that can be the level of damage to the road surface layer felt by the driver. In this study, it is known that the percentage of unevenness conditions that need to be addressed along the Hamadi - Entrop Kelapa Dua Road section (STA.034 + 300 - STA.039 + 300) is 82% good condition with routine maintenance handling suggestions, 18% moderate condition with periodic maintenance handling suggestions. This research identifies and provides suggestions regarding appropriate handling based on the IRI value scale.

Abstract

The Pappa River is one of the rivers in South Sulawesi which often experiences flooding during the rainy season. The flooding that occurred resulted in scouring of the river cliffs, so to prevent damage to the cliffs and the expansion of the river, it was necessary to plan cliff supports in the form of gabions. This research aims to determine the form and dimensions of effective slope strengthening planning in the Pappa River, Takalar Regency. Planning the dimensions of retaining walls includes design of gabion size and gabion stability and is analyzed using the gabion reinforcement capacity formula based on SNI 03-0090-1999. The calculated results of the overturning forces were 8.82 ≥ 1.5 and the shearing forces was 4.34 ≥ 1.5 so that the gabion construction was safe. Meanwhile, the gabion building will be placed on a cliff downstream of the Jenelata river, 200 meters long with dimensions 2 x 1 x 0.5, number of partitions 1 and capacity of 1 m³

Abstract

The SMK NU Sudirman Rogojampi building has problems with its clean water installation system, namely water distribution that is not smooth and sometimes jammed. This problem is thought to be due to the value of flow speed and pressure in clean water installations that do not meet the applicable minimum requirements. The purpose of this study was to evaluate the installation of clean water in the SMK NU Sudirman Rogojampi building. In this study, the author used the SNI 03-7065-2005 as a reference to calculate the clean water demand and conducted simulations using the Plumbing Pipe Flow Expert software. This software was employed to evaluate and simulate water flow in detail according to the guidelines specified in the SNI 03-7065-2005 related to plumbing systems in buildings. The results of this research indicate that the current clean water demand in the SMK NU Sudirman Rogojampi building is 16,800 liters per day or 16.80 m3 per day. Subsequently, a simulation of the clean water plumbing installation was performed using the Pipe Flow Expert software. In the first simulation, the generated water flow rate was in accordance with the field testing results, and the flow velocity only met the minimum requirements of SNI 03-7065-2005 for pipes numbered 1, 2, 12, 14, 18, 20, and 21. The water pressure also met the minimum requirements at nodes 5 and 24. In the second simulation, the results showed that the water flow rate, flow velocity, and pressure in the installation met the minimum requirements specified in SNI 03-7065-2005. Based on the simulation results, a suitable simulation was obtained, namely in the second simulation in the form of an improvement in the addition of an upper pusher pump from the rooftank to increase the speed and pressure of water in the clean water installation of the SMK NU Sudirman Rogojampi building.

Abstract

Soaking wood is often done by traditional communities, including the people of Jogotamu Hamlet, Loano Village, Purworejo Regency, to preserve wood to be used as construction materials such as battens and formwork. Testing the flexural strength of sengon wood beams, which are low grade wood, were immersed in river water to see the effect of the bending strength of sengon wood due to being submerged in river water. The main objective of this research is to determine the physical properties (water content, density, and specific gravity), Modulus of Rupture (MoR), and Modulus of Elasticity (MoE). Flexural strength testing of sengon beams measuring 760 mm x 50 mm x 50 mm with guidelines based on SNI-03-3959-1995 with variations without soaking, 7 days soaking, 14 days soaking, 21 days soaking, 28 days soaking, and 35 days soaking Flexural strength testing was carried out at the Structure Laboratory of the Civil Engineering Department, Faculty of Engineering, Tidar University, Magelang. The test results produced an average value of water content without soaking, soaking for 7 days, 14 days, 21 days, 28 days and 35 days respectively, namely 14.65%, 31.85%, 36.21%, 31.85%, 33.37%, and 32.84%. The average density values are respectively 0.40 gr/cm3, 0.57 gr/cm3, 0.66 gr/cm3, 0.60 gr/cm3, 0.64 gr/cm3, and 0.61 gr/ cm3. The average values of specific gravity are 0.35, 0.43, 0.48, 0.46, 0.48, and 0.46, respectively. The average Modulus of Rupture (MoR) values were 24.77 MPa, 23.82 MPa, 22.75 MPa, 23.86 MPa, 23.73 MPa, and 25.47 MPa, respectively. Meanwhile, the average Modulus of Elasticity (MoE) values are 3,495.20 MPa, 3,382.14 MPa, 3,893.05 MPa, 4,316.36 MPa, 1,689.34 MPa, 2,899.42 MPa. Based on Anova analysis, soaking sengon wood during this period resulted in the conclusion that there was no significant difference or no effect.

Abstract

Changes in land use in a watershed can significantly affect its hydrological characteristics. In addition to extreme rainfall events, land-use changes are among the factors contributing to flooding. This study aimed to determine changes in CN values due to land use changes in the Sarokah Watershed. Land use analysis was conducted by training objects on satellite image data acquired by Landsat 7, Landsat 8, and Sentinel 2A. From 2002 to 2013, there was a 9.03% decrease in the area of paddy fields and a 5.83% increase in the area of farms in the Sarokah Watershed. From 2013 to 2023, there was a 3.16% increase in built-up area and a 5.26% decrease in the area of paddy fields. According to the district's spatial plan, from 2023 to 2042, there will be a 29.15% increase in the built-up area and a 19.69% increase in the area of paddy fields. However, forest/tree areas and farm areas will decrease by 17.36% and 23.96%, respectively. Based on the 2023-2043 land use changes, the highest increases in CN values in 2043 will be in Sub-watersheds S15, S6, and S14 at 16.5%, 13.2%, and 10.8%, respectively.
