Abstract

As a region prone to earthquakes, lightweight concrete is strongly recommended to be used in construction development in Indonesia, especially buildings. If lightweight concrete is used as a non-structural element, it will reduce the total mass of the building which causes the load to be smaller and the design to be more economical as well. The addition of foam agent ADT in the concrete mix will produce air bubbles that can reduce the specific gravity of the concrete but will also reduce the compressive strength of the concrete. The addition of additive foam concrete ADT to the concrete mixture which has a function other than as a plasticizer also serves to stabilize the air bubbles produced by the foaming agent. The purpose of this research is to get the best composition of ADT foaming agent in concrete mixtures with additional additive foam concrete so as to produce better concrete resistance performance, determine the compressive strength, and water absorption of concrete with the use of variations in the composition of ADT foaming agent and the addition of additive foam concrete. The results show that the greater the density value of foam concrete, the higher the compressive strength value. While the percentage of water absorption produced in this study, the greater the density value of concrete with added foam, the smaller the absorption rate

Abstract

The road project in Lumajang Regency is one of the projects that experienced delays in work caused by several factors. One of them is uncertain weather such as continuous rain that affected sometask cannot be carried out on time or cannot be continued which had an impact on other work. The solution that can be used to accelerate project completion time is to carry out a comparative analysis of acceleration of implementation time on projects using the crashing method using alternatives to increase working hours and the number of workers to obtain maximum completion time for work that is on the critical path. In the crashing method, can generate the Crash Duration, Crash Cost, and Cost Slope analysis is carried out on work activities that are crashed. After that, the most efficient results of accelerating the duration of the project were obtained, namely by alternatively adding working hours which could speed up the project completion time by 25 days from the normal completion time of 219 days and a total cost of 9.465.138.216,75. Hitting the alternative of adding working hours can exceed the project completion target of the initial project plan duration.

Abstract

Pasuruan Regency provides an access road from Surabaya to Banyuwangi and Bali. The access from Surabaya to Banyuwangi and Bali is one of the roads with quite heavy traffic. In the future, of course, traffic volume will continue to become increasingly dense. Apart from that, Pasuruan Regency also has an alternative route that can quickly connect motorists to Pandaan, Sukorejo and Malang. Due to these factors, the potential for sound or noise pollution along roads in Pasuruan Regency is something that needs attention. The aim of this research is to examine the relationship between vehicle volume and noise due to the influence of traffic and to determine a map of the distribution of noise levels along JL Raya Pande Rejo, Legok to Jl. Soekarno Hatta Pasuruan city. This research uses Geographic Information System tools to display thematic maps. In order to get better results, this should be done during peak hours, namely 07.00 - 09.00 in the morning and 16.00 - 18.00 in the afternoon. From the noise level calculation, it was found that the highest noise in the morning was on Jalan Attorney General Suprapto (Segment 4) with a noise value of 81.74 (dBA) caused by the dense traffic volume on Jalan Attorney General Suprapto (Segment 4) of 2040.9 junior high school/hour. So the noise produced is also very large. The results of calculations using the multiple linear regression method, obtained an R2 value of 0.938 on Jalan Attorney General Suprapto with a fairly strong positive correlation value of 0.796 for MC vehicles. It can be concluded that a positive correlation means that the more vehicle volume, the higher the noise level received.

Abstract

The issue of environmental pollution has become a strategic issue because of its chain effects on all aspects of life. The construction of the City of Pekanbaru wastewater treatment facility is aimed at the treatment of domestic wastewater due to the density of the population and economic activity so that the quality of the environment is awakened. In this study, the risk of delay in the construction of a sewage treatment facility B1 in Pekanbaru was identified using the Relative Importance Index. (RII). The actual work duration is delayed against the duration of the original plan. Risk analysis uses a stochastic approach to the duration of work. In this analysis, the probability distribution function triangle distribution with 3-point estimate is used. This risk simulation uses @risk software with a maximum of 100,000 iterations. Work in the critical trajectory plays a crucial role in setting the project completion timetable. Initially, the estimated time of execution of the work was 1,075 days. After the analysis (Risk Pert Before Mitigation) the execution time with a 95% confidence rate reached 1,370 days, suggesting a potential delay of 295 days.
