Abstract
Time and cost are two important things in the implementation of construction projects. The greater the volume of the building will increase the period of implementation so that the higher the cost. Time and transaction costs provides challenges, and in the same time also opportunities for the construction planners to prepare the best construction plan with the optimal time and cost in order to complete the projects implementation. This research aims to obtain a relationship model of time, cost, and volume of the construction of Education Building in Aceh Province, particularly in the area of Bireun, Pidie, Aceh Utara, Aceh Selatan, Aceh Barat, Aceh Timur, Aceh Tengah, and Aceh Besar/Banda Aceh. The study is limited on the single storey building. The collected data as RAB, appointment/PHO, and images were obtained from the Education Department of Aceh province from 2008-2009 fiscal year resulted 105 (one hundred and five) projects, consist of Kindergarten/Early Childhood, Elementary, Junior High and Senior High school. This research involved the statistical calculation approach of Bromillow equation model and multiple regression analysis. The output indicates that the relationship of time and cost in those eight regions are exist (Model Bromillow). But, the recommended areas are only in Aceh Utara/Lhokseumawe at T = 12.75 C0, 26, and Aceh Barat at T = 6.68 C0, 36. As the result, the relationship model of cost, time, and volume is Y = 37.729 + 0.035X1 + 0.021X2 in Aceh Utara/Lhokseumawe. The finding of the relationship of those three models are recommended based on the linear hypothesis testing and the level of validation is <15%.
