Abstract

Glass bottle waste is non-biodegradable and concerns about its impact on the environment. One alternative is to use recycled glass bottle waste in a form of glass powder as a partial replacement for fine aggregate in concrete. This study compared the glass powder concrete containing 20% glass powder as a partial replacement for fine aggregate treated by steam curing to the normal concrete treated by immersion curing. To obtain a higher early strength, the glass powder concrete will be treated with steam curing method for total duration of 9 hours. The test results showed that glass powder concrete treated with steam curing experienced a significant increase of 40.7% in compressive strength at 1 day of age with a compressive strength of 7.84 MPa compared to normal concrete of 5.56 MPa, an increase of 57.0% at 3 days of age with a compressive strength of 16.88 MPa compared to normal concrete of 10.75 MPa, and an increase of 14.0% at 7 days of age with a compressive strength of 23.86 MPa compared to normal concrete of 20.94 MPa. The results of this study indicated that steam curing has the effect of increasing the early compressive strength of concrete at the age of 1, 3 and 7 days. In addition, the use of 20% glass powder as a partial replacement for fine aggregate can contribute to the utilization of non-biodegradable glass bottle waste.

Abstract

This study deals with analysis of structures using mixed Eulerian-Lagrangian description. Apart from generally used Lagrangian description which uses initial configuration as reference, the newly proposed uses one of actual configuration as reference. Therefore, the total displacement is decomposed into two portions, i.e., the portion covering displacement from initial into referential configuration called Eulerian displacement, and the portion covering displacement from referential configuration into current configuration called Lagrangian displacement. The new technique is suitable to be applied to several classes of structures such as frictional contact and tensile structures. Eulerian displacement is used to represent relative displacements between material points paired in a nodal point in which slip mode occurs, while Lagrangian displacement is used to represent mutual displacement of material points paired in a nodal point in which stick mode occurs. The method was applied to certain contact problems, and the results obtained agreed fairly well with existing results found in references.

Abstract

Soil condition at the Pulomas tower project site with a water level of 17 m below the ground and the hard soil at ground depth of 18 – 22 m, as well as the project location surrounded by houses and office buildings made the choice of bore pile as the foundation in this project. This condition is the background to the need for a bore pile capacity analysis in this tower project. The objective of this study is to analyze the bore pile capacity which is based on Standard Penetration Test (SPT) and Cone Penetration Test (CPT) and to be compared to the interpretation result of static loading test at a tower project location in East Jakarta. The ultimate bearing capacity of bore pile foundation was calculated using Meyerhof method and Reese & Wright method, and static loading test using Chin method. This study indicated that the ultimate bearing capacity using Reese & Wright method is closer to the interpretation result of static loading test from Chin method compared to Meyerhof method.

Abstract

LRT or Light Rail Transit is an alternative to mass transportation from the outskirts to the city center, helping to cut travel time and is integrated with public transportation and activity center locations. LRT effectiveness needs to be supported by LRT stations, the factors included are passenger queues and access bridge. This research delves into an analysis of the queuing system and access bridge at Kuningan LRT station, Jakarta, focusing on the expected waiting time in the system (card tapping time) and the queue at the north and south entrances. The research methodology involved a combination of observation and analytical methods, including data collection on the dimension of the access bridge and LRT station and the use of Queuing theory with multiple single servers' models for data analysis. The research findings reveal that during peak hours, with an estimated daily influx of 10,990 passengers arriving at Kuningan LRT and 10,096 departing from it, the average number of people in the queue is less than one person, with no prolonged queues. The analysis of data presented in this study reveals that the design and construction of the Kuningan LRT access bridge align closely with the pertinent development regulations. The study contributes to the knowledge of queuing systems and provides insights into the number of people estimated to be queuing at the Kuningan LRT station and to forecast how many queues may form during peak hours.

Abstract

The most common impediment to project work is a delay in implementing work activities. Even though the completion time has been calculated, there are several influencing factors, such as natural factors that cannot be predicted, late material delivery, a lack of workers that are not optimal when doing project work, and insufficient funds. In this case, the construction project of the Kampung Akuarium flats in Penjaringan area of North Jakarta was delayed from both technical and non-technical. The objective of this study is to identify the factors causing the project delays and the delay time of the project. This research was conducted by collecting data obtained and processed using Microsoft Project 2019 and the Critical Path Method (CPM) to help identify the problems. From the results that have been analyzed, critical paths include the structural work, finishing architecture 3rd floor, finishing architecture 4th floor, and finishing architecture 5th floor. If not completed immediately or delayed during implementation, the entire project schedule will be delayed. This has an effect where the initial contract plan was completed in 182 days to 259 days with a difference of 77 days or 11 weeks.
