Abstract

The development of Depok-Antasari Toll road construction was delayed by the work on the implementation of land work of 30.70% from the original plan presentation so that The initially planned time was completed in August 2019 extended to be completed in December 2019. In this study will analyze the acceleration of completion duration on The construction project of Depok–Antasari Toll road with an alternative to the number of heavy equipment. The purpose of this research is to know the cost of project that is physical and duration of time is faster by using the alternative. The results of the analysis was obtained that total project cost under normal conditions is IDR. 9,860,552,249.00 with the duration of project execution 130 working days. In the condition after accelerated with the addition of the number of heavy equipment alternative– 1 obtained a fee of Rp. 10,030,638,486.00 or more expensive 1.02% of the project cost in normal conditions and duration Project execution of 109 business days or faster 21 days from the normal duration. While the total cost of the project in the alternative condition–2 obtained Rp. 10,153,918,103.00 or more expensive 1.04% of the project cost under normal conditions and duration of project execution 104 days or faster 26 days from the normal duration. It can concluded that the acceleration of work by alternative method-1 is a more effective and economical acceleration alternative, because By applying an alternate acceleration–1. The duration of project work is faster than normal circumstances and does not experience a delay of employment from the planned time of 120 days. And the total budget cost of the project is cheaper compared to the alternative acceleration method-2.

Abstract

The Indonesian government stepped up infrastructure projects in the country for logistical and economic equality equalization, infrastructure in the form of a Freeway. This study aimed to analyze and compare the costs, timing, and precise method in Fullslab Precast erection work on 1 module. The data used are primary and secondary. Using the method of removal/erection with heavy equipment cranes. For the calculation of comparative analysis is obtained by analysis of the cost and time analysis. Field observations, and direct cost analysis calculation, and not directly into the calculations that will be loaded to get the proper method to the cost and time of work. The results of the right method are method 1 Crawler Crane at Rp 206.598.086,00.

Abstract

Low geographical conditions and flowed by many rivers and the reduction of retention ponds in Jakarta, then built a reservoir. However, during the implementation period, it was delayed by 9.74%. One of the things that can be done to overcome delays is to choose a method of implementation. The method is diversion and dewatering. The results of the analysis are expected to produce a large comparison of the costs and time of each method. From the analysis results, the cost of implementing the method of soil and rock diversion in the box culvert work is Rp. 363,935,953, while the sandbag diversion method is Rp. 332,805,831. For box culvert work using open pumping dewatering method, the required cost is Rp. 394,637,510. From these data, it was concluded that the difference in the cost of diversion sandbag and rock soil was Rp. 31,130,122. While rock soil and dewatering diversion are Rp. 30,701,557. As well as sandbag diversions with dewatering of Rp. 61,831,679. The results of observations of the implementation time obtained the conclusion that the work of box culvert with sandbag diversion method takes 35 days, and rock soil diversion 49 days while dewatering 63 days. By time comparison the sandbag diversion method is 14 days faster than rock soil diversion, and 28 days compared to the dewatering method. From these data, it can be concluded that in terms of cost and time, the sandbag diversion method is more economical and efficient than the other two methods.

Abstract

Infrastructure Development Certification of Human Resources Deputy Building 3 is planned as one of the supporting facilities to improve the quality of human resources, especially in the environment Badan Siber dan Sandi Negara, Indonesia. The purpose of this study is to find out the results of the analysis of the types of risk of K3 in the erection work in Project Pembangunan Infrastruktur Sertifikasi SDM Badan Siber dan Sandi Negara and know the types of K3 risks that play the most role that occur in erection work in Project Pembangunan Infrastruktur Sertifikasi SDM Badan Siber dan Sandi Negara. Using the research method of the survey method that will be validated by K3 Experts. The survey results from the respondent questionnaire were processed using the SPSS (Statistical Package for Social Science). To analyze risk, use the result of multiplying the average opportunity value and the average impact value.

Abstract

Soft soil with low bearing capacity presents challenges for infrastructure projects like the Kayu Agung–Palembang–Betung Toll Road. This study aims to identify the most efficient soil improvement method using the Value engineering (VE) approach and simulate associated risks. Using a descriptive quantitative method, data were collected through field observations, expert questionnaires, and project documents. Three methods were evaluated: preloading without vertical drains, with vertical drains, and vacuum preloading. Risk simulation was conducted using the Monte Carlo method with Crystal Ball software. Results show that preloading without vertical drains is the most cost-efficient but carries higher technical risks. Preloading with vertical drains offers a good balance between cost and stability, while vacuum preloading ensures optimal stability with higher costs.
