Abstract

ABSTRACT The implementation of this toll road construction project requires cost and time control. For this reason, research is carried out using the earned value analysis method in order to detect as early as possible if there is a cost overrun or delay that may occur in the implementation of a project. For the results of the analysis, it is found that based on the calculation of the performance analysis of the progress of this work, the cost performance index is 1.212 this value indicates a CPI > 1 which means that the expenditure is smaller than the planned budget. The schedule performance index is 0.889, this value indicates SPI < 1, which means that the work has been delayed from the plan. The result of the calculation of the estimated cost at the time of project completion (EAC) is Rp 19,035,298,952. So, the total cost needed to complete the project is Rp 19,035,298,952 indicating that the cost required for project completion is less than the planned budget of Rp 23,073,860,159, from this value the difference is Rp 4,038,561,207. From the analysis of the estimated completion time or Estimate Completion Date (ECD), it is found that the time required to complete the project is 465 days, which means that the work has been delayed by 15 days.

Untuk itu dilakukan penelitian dengan menggunakan metode earned value analisys agar dapat mendeteksi sedini mungkin bila terjadi pembengkakan biaya maupun keterlambatan yang mungkin terjadi dalam pelaksanaan suatu proyek. Untuk hasil analisis yang didapatkan bahwa berdasarkan perhitungan analisa prestasi progress pekerjaan ini, indeks penampilan biaya bernilai 1,212 nilai ini menunjukkan CPI > 1 yang artinya pengeluaran lebih kecil dari anggaran yang direncanakan. Indeks penampilan jadwal bernilai 0,889 nilai ini menunjukkan SPI < 1 yang artinya pekerjaan mengalami keterlambatan dari rencana. Hasil perhitungan prakiraan biaya saat penyelesaian proyek (EAC) Rp 19.035.298.952. sehingga total biaya yang dibutuhkan untuk menyelesaikan proyek adalah Rp 19.035.298.952 menunjukkan bahwa biaya yang diperlukan untuk penyelesaian proyek lebih kecil dari anggaran yang direncanakan sebesar Rp 23.073.860.159, dari nilai tersebut didapat selisih sebesar Rp 4.038.561.207. Dari hasil analisa prakiraan waktu penyelesaian atau Estimate Completion Date (ECD) didapat waktu yang dibutuhkan hingga akhir proyek selama 465 hari yang artinya pekerjaan mengalami keterlambatan selama 15 hari. Kata kunci: Waktu, Biaya, konsep nilai hasil (Earned Value Concept), PVD-Preloading.

Abstract

ABSTRACT A new product of lightweight concrete that has a low specific gravity that is increasingly used in the world of construction is foam concrete. In this study, testing the addition of superplasticizers to the foam concrete mixture was carried out, by analyzing the effect of adding superplasticizers as much as 0.3% of the amount of cement on the process of setting time and compressive strength of foam concrete. The purpose of the study was to determine the effect of adding superplasticizers as much as 0.3% of the amount of cement on the process setting time and compressive strength of foam concrete. In this study, the method used was an experimental method. The results showed that the addition of superplasticizers to the concrete mixture can make the cement binding time longer than without the addition of superplasticizers to the concrete mixture. While in testing the compressive strength of concrete, there is a significant increase in concrete strength in concrete variations with the addition of superplasticizers, this is because the use of added superplasticizers can reduce water use so that the cement water factor becomes lower and improves concrete quality. Keywords: Concrete Foam, Superplasticizer, Compressive Strength ABSTRAK Produk baru beton ringan yang mempunyai berat jenis rendah yang semakin banyak digunakan dalam dunia konstruksi yakni beton busa. Pada penelitian ini dilakukan pengujian penambahan superplasticizer pada campuran beton busa, dengan menganalisis pengaruh penambahan superplasticizer sebanyak 0,3% dari jumlah semen terhadap proses setting time dan kuat tekan beton busa. Dengan tujuan penelitian adalah untuk mengatahui pengaruh penambahan superplasticizer sebanyak 0,3% dari jumlah semen terhadap proses setting time dan kuat tekan beton busa. Dalam penelitian ini metode yang digunakan adalah metode eksperimental. Hasil penelitian menunjukan dengan adanya penambahan superplasticizer kedalam campuran beton dapat membuat waktu ikat semen lebih lama dibandingkan tanpa penambahan superplasticizer kedalam campuran beton. Sedangkan pada pengujian kuat tekan beton terjadi peningkatan kekuatan beton secara signifikan pada variasi beton dengan penambahan superplasticizer, hal tersebut dikarenakan penggunaan bahan tambah superplasticizer dapat mengurangi pemakaian air sehingga faktor air semen menjadi lebih rendah dan meningkatkan mutu beton.
