"Kondisi dalam proyek konstruksi sangat dipengaruhi oleh besarnya tingkat ketidakpastian. Umumnya ketidakpastian biasa terjadi pada tahapan awal proyek. Pemahaman mengenai ruang lingkup yang kurang, pengalaman si pembuat jadwal yang kurang, serta estimasi biaya yang tidak tepat semakin menyebabkan ketidakpastian semakin besar. Membuat jadwal yang realistis sesuai dengan pelaksanaan adalah suatu hal yang sangat sulit untuk dicapai. Walaupun perencanaan dan estimasi yang matang sudah dilakukan, terkadang pada proyek yang tipikal juga mengalami overrun pada perkiraan biayanya. Resiko dan ketidakpastian dalam penjadwalan suatu proyek akan berhubungan dengan biaya, mutu dan waktu pada tahapan pelaksanaan proyek. Langkah awal yang tepat dalam menghadapi ketidakpastian adalah dengan memberikan perhatian pada penjadwalan, dengan mengukur ketidakpastian tersebut. Teknik dan metode dalam mengelola resiko secara lebih efektif dapat membantu untuk mengatasi tantangan terhadap ketidakpastian yang mengancam kesuksesan proyek. Monte Carlo merupakan metode statistik yang digunakan untuk mengidentifikasi resiko/peluang dan mengevaluasi kemungkinan. Metode ini adalah yang paling sering digunakan dalam melakukan analisa resiko kuantitatif. Prosedur Simulasi Monte Carlo adalah derivasi dari realisasi atau hasil keluaran sintetik dari durasi aktivitas yang relevan. Setelah realisasi ini dihasilkan, teknik penjadwalan standar dapat digunakan.

Project construction condition was very influenced by level of uncertainty. Generally, the uncertainty commonly happened at the initial phase of the project. Less understanding about the scope definition, less experience of the scheduler and also imprecise cost estimate cause ever greater uncertainty. Realistic scheduling as according to project execution was very difficult to be reached. Although the estimation and planning have been done maturely, evenly sometimes for typical project had overrun from estimate costs.

Risk and uncertainty in project scheduling related to cost, quality and time when project executed. Early step in facing uncertainties were giving attention at scheduling, with measuring the uncertainties. Technique and method in risk management effectively can assist to overcome challenges through uncertainty that threatening project successfulness. Monte Carlo represent statistical methods used to identify risk/chance and evaluate possibilities. This method commonly used for quantitative risk analysis.

Monte Carlo simulation procedure were derivated from realization or synthetic output from dates of relevant activities. After this outcome yielded, standard scheduling technique can be used. Monte Carlo simulation method for cost and time of Wwest Jakarta Mayor Office Project taken value level of confidence 70 %. Validating through cost and time to entirely prohect realization shows good result, where the differences of real cost with simulation was 8,86 % and for time 7 %. Project activity that most have an effect to entire project was iron installation for beam floor plate zone 2 at twelve floor with SSI value 39 %."

"Dosimeter luminisensi LiF:Mg,Ti (TLD-100) merupakan detektor yang memiliki densitas material hampir ekivalen dengan jaringan tubuh manusia dan merupakan pilihan detektor yang terbaik untuk pengukuran dosis radiasi in vivo. Selain itu, TLD-100 memiliki kelemahan seperti ketidakseragaman respon, efek fading, dan ketergantungan respon energi. Keberadaan fading dan variasi sensitivitas sangat mempengaruhi respon TLD. Detektor TL memiliki respon yang bersifat tidak linier dari rentang dosis rendah sampai dosis tinggi. Keakurasian dalam estimasi dosis sangat penting dalam melakukan audit dosimetri. Dalam penelitian ini dilakukan usaha peningkatan akurasi proses bacaan TLD melalui pengurangan variasi respon TLD dengan memperkecil rentang rata-rata respon pada nilai ±3%, penentuan faktor koreksi fading berdasarkan variasi respon TLD 0.05%, mencari respon TLD terhadap perubahan energi pada rentang RQR dan Cobalt 60. Selain itu dilakukan juga evaluasi penggunaan metode bacaan menggunakan kondisi TTP dosis rendah dan TTP dosis tinggi. Berdasarkan pengelompokan TLD dengan variasi respon 0.05%, diperoleh koreksi fading y = 122.962 x-0.049, fungsi ini dapat digunakan untuk mengkoreksi bacaan TLD jika pembacaan dilakukan pada hari yang berbeda. Dengan menggunakan variasi respon TLD 3% diperoleh respon TLD yang menurun pada RQR4-RQR7, dan menaik pada RQR8-RQR15. Diketahui pengaruh pengaturan TTP memberikan perbedaan rasio bacaan dosis rendah terhadap dosis tinggi pada TLD yang berdampak nilai faktor kalibrasi TLD berubah sebesar 1.05, 1.03, dan 1.05 berturut dengan tegangan tabung 40, 70 dan 150 kV, sedangkan untuk cobalt 60 dengan variasi dosis 2, 1, dan 0.1 Gy perbandingannya sebesar 0.95, 0.96, dan 1.00. Estimasi ketidakpastian gabungan tipe A dan tipe B diperoleh rata-rata adalah sebesar 5.77% dengan batas tingkat kepercayaan 95%, dua standar deviasi.

Luminiscent dosemeters LiF: Mg, Ti (TLD-100) is detector that has an equivalent density material compare to human tissue and the best choice for in-vivo radiation dose measurement. On the other hand, TLD-100 has some weaknesses such as the ununiform responses, fading effects, and energy response dependent. The presence of fading and variations of sensitivity are greatly affect to the response of TLD. The response of detector TL is not linear from low dose up to high dose. Accuracy in dose estimation is essential in performing dosimetry audit.

This study aim to increase the accuracy of TLD reading process by reducing the variation response of TLD with minimizing the response range within ± 3%, measuring of the fading correction factor using TLD with response variation ±0.05%, determining TLD response dependency in energy RQR range and Cobalt 60. In addition, this work also evaluate the reading method using low and high dose TTP setting. Based on ±0.05% TLD response variation grouping, fading correction function is y = 122.962 x-0.049, this function can be used to correct the TLD readings when readings performed on different day.

By using a variation of TLD response ±3%, it is found there is a decreased response in TLD, over RQR4-RQR7, and an increased over RQR8-RQR15. It is found that different setting of TTP will affects readings result low dose ratio with the high dose will change on TLD of calibration factor value 1.05, 1.03, and 1.05 respectively with a tube voltage of 40, 70 and 150 kV, while for cobalt 60 with variation of doses around 2, 1, and 0.1 Gy the value of ratio around 1.05, 1.04, and 1.00. Estimation uncertainty both of type A and type B are obtained on the average of 5.77% with a limit of level confidence 95%, two standard deviations."
