ABC Company is an agent of network construction, operation, and maintenance. ABC Company is currently implementing the STTF (Shit to the Front) project, which is the project to add FTTH (Fiber to the Home) networks in areas that can have high customer demand. One of the STTF project construction sites is the Indra Prahasta II housing location. However, the project is currently experiencing work delays due to the Covid-19 disaster in Indonesia. Delays in project execution can result in potential prospects choosing another company that provides similar services. The project schedule can be accelerated using the crashing method and TCTO (Time Cost Trade-Off) analysis to solve this problem. This research's acceleration will be carried out with alternatives for adding 3 hours, 2 hours, 1 hour, and an alternative to increasing workers' number. This project has an average duration of 55 working days with a total cost of Rp 604,124,460. The results obtained from data processing, on the alternative of adding 1 hour of overtime work, the total duration becomes 54 working days with total project cost is Rp 605,734,138. In addition to 2 hours of overtime work, the project's total duration can be reduced to 54 days with a total project cost Rp 606,803,619. And for the addition of 3 hours overtime, the total duration can be shortened to 54 days with a total cost of Rp 606,803,619. As for increasing the number of workers, project work duration can be shortened to 54 working days with a total project cost Rp 604,556,748

Today, Construction based Industry is the prospering industry which has a high economical influence on any nation. Delay in the huge construction project increases the total project cost. Henceforth, uncertainties as well as risks must be significantly regarded during the project. For organizing and completing the projects in a financially, timely and qualitatively accountable manner, careful scheduling of projects is compulsory. Effectual scheduling of project assures project success. This study concentrates on qualitative analysis, risk identification, together with quantitative analysis. The targets are i) to ascertain the key risk aspects that disturb the project schedule, and ii) to find the probability of finishing the project within specified time. Questionnaires are distributed amongst 20 industry practitioners with disparate experience from [1] to [25] years.  Quantitative analysis is made by the methods like Monte Carlo simulation (MCS) and PERT. @RISK by Palisade corp. is utilized for MCS.

Prior to the construction of a new hydroelectric facility on the Toulnustouc River, Quebec, Canada, optimization was carried out on the dams and spillway design, resulting in a CAN$6 million reduction in the total project cost while improving flood control. This result was obtained using a new approach to the design of civil works, in which the dam and spillway were in complete interaction with one another. In this approach, the possibility of increasing the freeboard of the dams more than that usually required by Hydro-Québec criteria was allowed. The additional freeboard or reservoir volume is strictly assigned to flood control to reduce the maximum released discharge to existing downstream facilities. The raising of dam crests generates additional cost that is more than compensated for by a reduction in spillway capacity and cost.Key words: flood, control, cost, spillway, dam, optimization, security, freeboard.

In the implementation of construction project activities there are thre things that influence the success and failure of the project: time, cost and quality. The success of a project is usually seen from the timing of completion which is relatively short but without neglecting the quality of the project work. Appropriate and targeted project management and management are required to ensure the time, cost, and quality of the project. This is certainly to avoid a variety of undesirable things such as late settlement, swelling costs, quality failures, and so on that could have an impact on project failure and the emergence of the cost of fines. The purpose of this study is to calculate changes in cost and time of project implementation with alternatives to additional working hours (overtime) comparing the results between normal and cost changes after the addition of working hours (overtime). The data used in this research is secondary data obtained from contractor implementing. Arrow diagram The results program are critical paths and cost increases due to the addition of working hours (overtime) while the result of the time cost trade off method is the acceleration of duration and the increased cost due to the acceleration of duration in any accelerated activity. The results of this study indicate that the total project time and cost under normal conditions is 508 days at a cost of Rp 22.240.655.701  with the addition of 3 hours of overtime work in the duration of crashing 485 days and at a cost of Rp 23.252.220.373,34

ABSTRACT                                                                         In the construction of a construction project, there are three main elements: time efficiency, minimal costs, and appropriate quality. This study aims to calculate changes in the cost and time of project implementation with variations in overtime and additional workforce. Data analysis using Microsoft Project 2010 program and Time-Cost Trade-Off method. The results of this study indicate that (1) the optimum time and costs due to overtime are obtained at the project age of 235 working days with a total project cost of IDR 8,438,038,832 with a project time efficiency of 5 days (2.13%) and a project cost efficiency of IDR 3.559,695 (0.042%). (2) The optimum time and cost due to the addition of labor is the best choice with the results obtained at the project age of 226 working days with a total project cost of IDR 8,429,832,759 with a project time efficiency of 14 days (6.19%) and cost-efficiency. project amounting to Rp. 11,779,674 (0.14%). ABSTRAKDalam pelaksanaan pembangunan suatu proyek konstruksi, terdapat tiga unsur utama yaitu waktu yang efisien, biaya minimal dan mutu yang sesuai. Tujuan dari penelitian ini adalah menghitung perubahan biaya dan waktu pelaksanaan proyek dengan variasi lembur dan penambahan tenaga kerja. Analisis data menggunakan program Microsoft Project 2010 dan metode Time Cost Trade Off. Hasil penelitian ini menunjukkan bahwa (1) Waktu dan biaya optimum akibat lembur didapat pada umur proyek 235 hari kerja dengan total biaya proyek sebesar Rp8.438.038.832 dengan efisiensi waktu proyek sebanyak 5 hari (2,13%) dan efisiensi biaya proyek sebesar Rp3.559.695 (0,042%). (2) Waktu dan biaya optimum akibat penambahan tenaga kerja menjadi pilihan terbaik dengan hasil yang didapat pada umur proyek 226 hari kerja dengan total biaya proyek sebesar Rp8.429.832.759 dengan efisiensi waktu proyek sebanyak 14 hari (6,19%) dan efisiensi biaya proyek sebesar Rp11.779.674 (0,14%).

Rural development policies aim to raise the people living in rural areas to the level of the cities in agricultural, economic, social and cultural issues and to increase their living standards. Rural areas in Turkey are areas where a significant portion of the population is engaged in agriculture. Improving the infrastructure of agricultural enterprises will increase the living standards of the people living in rural areas. Turkey should support its rural infrastructure in order to be competitive in rural development. In this sense, with the order of the Ministry of Agriculture and Forestry of the Republic of Turkey, the first 50% grant support, and the Rural Development Investments Support Program started to be implemented in the whole country with the decision of the Council of Ministers in 2011. In 2021, the support continued in two different parts under the name of agricultural-based economic investments and supporting rural economic infrastructure investments. In the study, Kastamonu province, which has an important potential, was examined in terms of rural development. The contribution of the supports provided with the program "Supporting Economic Investments Based on Agriculture within the Scope of Rural Development Supports" implemented in the province in 2021 has been evaluated. There have been 18 project applications for agricultural-based economic investments in Kastamonu province for 2021. Their total project cost is 12.8 million TL. 279 project applications were made to support rural economic infrastructure investments. The total project cost of these was 30.8 million TL.
