Abstract

Earned Value Analysis (EVA) is a powerful and effective tool in construction project cost and schedule control. With proper implementation, EVA can help project managers to keep the project within the set budget and schedule, and increase the chances of overall project success. Although it faces challenges in its implementation, the benefits derived from using EVA far outweigh them, making it an invaluable approach in construction project management. Based on the BCWP value and the percentage of work realization obtained from the calculation until week 33 is Rp.6,601,973,900, - less than the BCWS value until week 33, which is Rp.7,686,078,000, - with a difference in realized and planned costs of Rp.1,084,104,100 and Rp.1,084,104,100. .084,104,100 and the percent progress realization of 68.699% is less than the percent plan which is 79.98%, with a difference in percent realization and plan of 11.28% this shows that until week 33 the project is delayed by 3 weeks from the scheduled plan. By using the BCWP value and the CPI value, the estimated value of the remaining cost or ETC is Rp.2,758,926,605, - and the estimated final cost of the project or EAC is Rp.8,609,028,353, 48 the EAC value is smaller than the planned budget cost of Rp.9,610,000,000, - meaning that the Earned Value to be obtained by the company is Rp.1,000,971,647

Abstract

This study aims to describe the process of monitoring the quality of concrete in the retaining wall construction project at the South Sumatra High Prosecutor's Office. The concrete used is a type of ready mix quality K-175, with supervision carried out through the stages of slump test, sample collection and curing, and concrete compressive strength test. This research uses a qualitative descriptive method with a case study approach. The results showed that the concrete slump value was within the specification range (10-12 cm), while the concrete compressive strength test results at the age of 7 days reached an average of 181.469 kgf/cm² and at the age of 14 days amounted to 188.397 kgf/cm². These values indicate that the concrete has met the technical strength requirements for non-structural structures. Some field constraints such as high rainfall and delays in concrete delivery can be overcome by rescheduling, the use of work area protection, and good logistical coordination. Overall, the concrete quality in this project was in accordance with the set standards.

Abstract

This study aims to evaluate the suitability between planning and realization of implementation time in the retaining wall construction project at the South Sumatra High Prosecutor's Office. Using quantitative descriptive method and case study approach, data was obtained through direct observation, documentation, and analysis of weekly and monthly project reports. The S-curve is used as the main tool in monitoring the deviation between the planned and realized work weights. The results showed that in general the project was on schedule, although there was a negative deviation in weeks 7 to 9 due to weather constraints, material delays, and labor shortages. However, through acceleration strategies such as overtime and improved logistics management, delays were minimized. Structured time monitoring proved effective in keeping the project within schedule tolerance limits. This research emphasizes the importance of an adaptive monitoring system as well as good coordination between teams as keys to successful implementation of construction projects.

Abstract

The increasing number of employees and vehicles at the Head Office of PT Bukit Asam Tbk Tanjung Enim has created a growing demand for adequate parking facilities. Limited parking space tends to encourage the use of on-street parking, which may lead to traffic congestion and reduce the comfort of the office environment. This study aims to analyze parking capacity and provide optimal management recommendations. The research was conducted through a preliminary survey, literature review, collection of primary and secondary data, and descriptive analysis to determine the parking space requirements for each type of vehicle. The results show that the maximum parking duration for cars and motorcycles is 440 minutes, with peak volumes of 142 vehicles/hour for cars and 124 vehicles/hour for motorcycles at 06.00–06.59. The parking index reached 96.52% for cars and 73.33% for motorcycles. The available static capacity is 115 SRP for cars and 210 SRP for motorcycles, while the ideal parking space requirement is 122 SRP for cars and 151 SRP for motorcycles. In conclusion, the current parking capacity is sufficient for motorcycles but insufficient for cars. Therefore, optimization of parking patterns, such as adjusting the parking angle to 90°, is necessary to increase capacity and improve convenience for all employees.

Abstract

This study aims to examine the effect of utilizing plastic waste as an additive material in lightweight concrete on the compressive strength of the concrete. The testing was conducted with variations in the percentage of plastic waste at 5%, 10%, and 15% in the concrete mix, then compared to normal concrete without plastic waste. The results showed that the highest compressive strength was obtained in the mix with 5% plastic waste, reaching 29.09 MPa, which is slightly higher than the normal concrete with a compressive strength of 28.24 MPa at 28 days of age. At 10% and 15% plastic waste, the compressive strengths were 28.45 MPa and 28.03 MPa respectively, indicating a decrease compared to the 5% mix. These data suggest that the addition of plastic waste does not consistently improve the quality of concrete, so the optimal percentage must be carefully determined to avoid reducing the concrete’s strength. This study illustrates that the utilization of plastic waste as an additive in lightweight concrete can enhance compressive strength at certain levels, but excessive use may negatively affect the concrete’s performance.Keywords: Plastic Waste, Environmentally Friendly Lightweight Concrete

Abstract

Roads are essential land transportation infrastructure; therefore, the quality of pavement must be maintained to ensure optimal performance and service life. One approach to improving the quality of flexible pavement in the Asphalt Concrete-Wearing Course (AC-WC) layer is by utilizing alternative materials as filler. This study investigates the effect of adding bamboo ash as an additional filler in AC-WC mixtures with PG 76 asphalt on Bulk Density and Marshall Stability. Bamboo ash contains silica (SiO₂) and exhibits pozzolanic properties that have the potential to enhance mixture performance. The bamboo ash content variations used were 0%, 0.5%, 1.0%, 1.5%, and 2.0% by total aggregate weight. Testing was conducted using the Marshall Test method in accordance with the 2018 Bina Marga General Specifications, Revision 2. The results showed that adding 1.0% bamboo ash produced the highest Bulk Density value of 2.310 g/cc, while the highest Marshall Stability value was obtained at 0.5% with 1,168.3 kg. All mixture variations achieved residual Marshall Stability values above the minimum requirement (≥90%), with the highest value of 91.47% recorded at 0.5%. Based on the balance between density and stability, the optimal bamboo ash content as an additional filler in AC-WC PG 76 is in the range of 0.5%–1.0%..Keywords: PG 76 asphalt, AC-WC, bamboo ash, filler, stability, density.

Abstract

Soil is one of the primary materials in construction, serving as the medium that supports the loads of buildings and other infrastructure. The stability of the structures built on it greatly depends on the physical and mechan- ical properties of the subgrade soil. However, not all soils possess characteristics that are ideal for construc- tion. One type of soil that often poses technical problems is expansive clay. This soil is known for its tendency to swell when wet and shrink when dry due to its high content of active clay minerals. Not all soils are suitable for use in construction, as some subgrade types have issues related to both bearing capacity and settlement (Lestari & Lestari, 2014). Therefore, expansive clay requires special treatment before it can be used as a construction medium. One common technique for improving soil properties is compaction (Diana et al., 2022). Compaction is carried out to increase the dry unit weight of the soil, reduce porosity, improve bearing capac- ity, and minimize the potential for volume change due to variations in water content. In general, compaction alters several soil characteristics, such as dry density, void ratio, shear strength parameters, and soil volume (Lubis, 2007). Through compaction, it is expected that the soil will become more stable both structurally and mechanically. To determine the optimal compaction condition, a laboratory test known as the Standard Proctor Test is conducted. On the other hand, to assess the extent of improvement in the mechanical properties of soil after compaction, a shear strength test such as the Unconfined Compression Test (UCT) is used. UCT is a simple method for measuring the strength of cohesive soils without the application of confining pressure. Shear strength is the soil's ability to resist shear stress when subjected to loading (Agustina & Elfrida, 2019). Through this test, the value of Unconfined Compressive Strength (qu) can be obtained, which can then be used to determine the undrained shear strength (su) of the soil. The combination of the Standard Proctor Test and the Unconfined Compression Test becomes essential in analyzing the relationship between compaction level and the shear strength characteristics of expansive clay. Water content during compaction plays an important role in determining the values of unconfined compressive strength and shear strength. Expansive clay samples compacted at optimum moisture content (OMC) using the Standard Proctor method yield the highest compres- sive and shear strength values (Yunus & Annisa, 2023). Keywords: Compaction, Shear Strength, Expansive Clay Soil, Water Content

Abstract

This research is an experimental study aimed at investigating the effect of bamboo ash filler on the characteristics of Asphalt Concrete-Binder Course (AC-BC) using PG 76 hard asphalt. The variations of bamboo ash filler used were 0%, 0.5%, 1%, 1.5%, and 2% of the total filler weight. The tests conducted included the Marshall test to obtain stability, flow, VIM, VMA, VFB, and density parameters. The results indicate that the addition of bamboo ash as a filler affects the characteristics of the mixture. The stability values still meet the 2018 Bina Marga specifications (revision 3), although a decrease was observed at certain levels. Bulk density fluctuated with the addition of filler, while VIM, VMA, and VFB values changed according to the bamboo ash content. Overall, bamboo ash can be considered as an alternative filler in AC-BC mixtures, provided that the optimum content is maintained to avoid reducing the mixture’s performanceKeywords: filler, bamboo ash, AC-BC, PG 76 asphalt, Marshall

Abstract

This study aims to analyze flood discharge characteristics based on hydrological data and to assess the effectiveness of implementing a polder and retention pond system for flood control. The research methods include hydrological analysis using maximum annual rainfall data (2010–2023) from the Meteorology, Climatology, and Geophysics Agency (BMKG), frequency and distribution analysis (Normal, Log Normal, Gumbel, and Log Pearson Type III), distribution suitability testing, rainfall intensity calculations using the Mononobe formula, and determining the planned discharge using the rational method. The analysis results indicate that the rainfall data conforms to a normal distribution with a mean of 469.43 mm and a standard deviation of 93.44 mm. The planned discharge for a 50-year return period is 0.70 m³/s. The planned capacity of the polder and retention pond is sufficient to accommodate this discharge, thus this system is considered effective in reducing flood risk in the study areaKeywords: Polder, Retention Pond, Flood, Hydrology, Tanjung Senai
