Penulis  melaksanakan penelitian yang berkaitan dengan estimasi biaya proyek dengan menggunakan metode Cost Significant Model pada proyek pembangunan gedung kargo bandara. Hal ini didasarkan rumusan masalah yang penulis ajukan, yakni (1)  komponen item pekerjaan apakah yang berpengaruh secara signifikan terhadap biaya total pembangunan kargo bandara?, (2) bagaimana model estimasi biaya pembangunan kargo bandara dengan menggunakan metode Cost Significant Model?, dan (3) bagaimana perbandingan akurasi model estimasi biaya pembangunan kargo bandara dengan menggunakan  metode Cost Significant Model?.                Penelitian ini menggunakan pendekatan kuantitatif dengan mengambil data biaya berupa rencana anggaran biaya (RAB) pembangunan kargo bandara di 3 provinsi, yakni Provinsi Jawa Barat (di Majalengka), Provinsi Jawa Tengah (di Kulon Progo), dan Provinsi Sumatra Utara (di Medan). Kemudian, biaya pekerjaan yang dimasukkan ke dalam analisis adalah (1) pekerjaan persiapan, (2) pekerjaan struktur, (3) pekerjaan arsitektur, (4) pekerjaan plumbing, (5) pekerjaan mekanikal, dan (6) pekerjaan elektrikal. Selanjutnya, analisis data dilakukan sesuai tahapan berikut ini (1) perhitungan time value, (2) menentukan cost significant item, (3) uji persyaratan untuk analisis, (4) analisis data, berupa uji analisis linier berganda, (4) pengujian model dengan Cost Model Factor (CMF).                Hasil analisis penelitian ini adalah (1) komponen item pekerjaan yang berpengaruh secara signifikan terhadap biaya total pembangunan kargo bandara berdasarkan perhitungan dengan metode cost significant model adalah (a) X2 Pekerjaan Struktur: 63,93%, (b) X3 Pekerjaan Arsitektur: 27,77%, dan (c) X6 Pekerjaan Elektrikal: 5,69%; (2) Model estimasi biaya pembangunan kargo bandara dengan menggunakan metode Cost Significant Model di 3 provinsi adalah Y = 208,453 + 0,747 X2 + 1,505 X3 + 1,844 X6; (3) Perbandingan akurasi model estimasi biaya pembangunan kargo bandara di 3 provinsi dengan menggunakan  metode Cost Significant Model diperoleh rata-rata 47,68%, serta menurut Standar AACE International bahwa hasil estimasi biaya ini termasuk ke dalam class 2 dengan End Usage: Control or Bid/Tender sesuai tabel 2.2 pada halaman 25.

<p>Salah satu elemen penting dalam proyek adalah tahap estimasi biaya. Sering kali saat proyek masih pada tahap awal ,informasi untuk mengestimasi belum terlalu detail, sehingga hasil estimasi cenderung tidak begitu akurat, oleh karena itu dibutuhkan model estimasi biaya yang dapat menjelaskan sebagian besar proyek berdasarkan informasi yang sesedikit mungkin. Metode estimasi yang digunakan adalah <em>Cost Significant Model</em>, model ini menggunakan biaya pekerjaan yang secara signifikan berpengaruh terhadap biaya total proyek. Tujuannya adalah untuk mengetahui tingkat keakuratan model estimasi biaya pada pembangunan jembatan beton bertulang terhadap biaya actual proyek. Data dihimpun dengan menggunakan metode <em>sampling </em>dan diperoleh berupa 5 paket proyek konstruksi jembatan beton bertulang dari tahun 2013 sampai 2017. Dengan hasil yang didapatkan berupa persamaan model estimasi yaitu Y=-19.832.201,418+1,948X1  +0,889X2  +4,274X3, dengan <em>Cost Model Factor </em>sebesar 0,9844. Tingkat keakuratan hasil estimasi berkisar antara -3,37% sampai +1,69%. Dilihat dari persentase keakuratan hasil estimasi tersebut, <em>AACE International </em>menunjukkan model ini dapat digunakan untuk pengecekan perkiraan penawaran.</p>

Plasma Lactate Level

Changes in myocardial metabolism can be detected externally by registration of time-activity curves after administration of radioiodinated fatty acids. In this scintigraphic study the influence of lactate on fatty acid metabolism was investigated in the normal human myocardium, traced with 123l-17-iodoheptadecanoic acid (123l-17-HDA). In patients (paired, n = 7) lactate loading decreased the uptake of 123l-17-HDA significantly from 27 (control: 22-36) to 20 counts/min/pixel (16-31; p <0.05 Wilcoxon). The half-time value increased to more than 60 rriin (n = 5), oxidation decreased from 61 to 42%. Coronary vasodilatation, a well-known side effect of lactate loading, was studied separately in a dipyridamole study (paired, n = 6). Coronary vasodilatation did not influence the parameters of the time-activity curve. These results suggest that changes in plasma lactate level as occurring, among other effects, during exercise will influence the parameters of dynamic 123l-17-HDA scintigraphy of the heart.

Parameter Values

Optimal fitting of a myocardial time-activity curve is accomplished with a monoexponential plus a constant, resulting in three parameters: amplitude and half-time of the monoexponential and the constant. The aim of this study was to estimate the precision of the calculated parameters. The variability of the parameter values as a function of the acquisition time was studied in 11 patients with cardiac complaints. Of the three parameters the half-time value varied most strongly with the acquisition time. An acquisition time of 80 min was needed to keep the standard deviation of the half-time value within ±10%. To estimate the standard deviation of the half-time value as a function of the parameter values, of the noise content of the time-activity curve and of the acquisition time, a model experiment was used. In most cases the SD decreased by 50% if the acquisition time was increased from 60 to 90 min. A low amplitude/constant ratio and a high half-time value result in a high SD of the half-time value. Tables are presented to estimate the SD in a particular case.

Significant Model

SummaryA panel of haemostatic tests was perfomed on 400 primiparous women at 28 weeks to test whether one or more could predict the development of pregnancy complications. Fifteen women subsequently developed pre-eclampsia with significant proteinuria and 13 delivered growth retarded infants. There were no significant differences between mothers in the pre-eclampsia group and 22 randomly selected controls. A stepwise logistic discriminant analysis of the data did not produce a significant model. In the growth retarded group only beta thromboglobulin levels were significantly lower than in the controls (p <0.05), although in the logistic discriminant analysis the inclusion of both beta thromboglobulin and fibrin degradation products led to a borderline significant improvement in fit of the model. We conclude that the haemostatic variables studied are not significantly changed at 28 weeks nor clinically useful predictors of either pre-eclampsia or fetal growth retardation.

Asking Questions

This series of videos, Chief Resource Management Officer, decontextualizes and amplifies mundane tasks and actions, exposing an inherent absurdity and dry humor. Conceptually and visually, I engage themes of corporate management structures, cult dynamics, and Sisyphean tasks. Within this work, I am primarily interested in developing situations that disrupt familiar social and political hierarchies. Utilizing recognizable apparel and gestures, I playfully occupy the threshold of absurdity while asking questions about time, value, routines, and the monetization of work and/or presence.
