PD Pasar Jaya manages 153 markets spread across Jakarta. Market building is a place of public services, in order to provide excellent service to the community, it is important to maintain it properly. Maintenance management of PD Pasar Jaya is still far from the expected. The purpose of this study was to determine the effect of directly and indirectly from the condition of the building and maintenance resources to user satisfaction through maintenance management. The research method is by taking a sample of 14 buildings market, then use the check list building condition assessment visually and dissemination of survey questionnaires to 216 respondents, namely the market manager, the kiosk, and visitors. The questionnaire consisted of four variables: the condition of the building (X1), maintenance resources (X2), as an variable, independent maintenance management (Y) as variable, an intervening while user satisfaction (Z) as the dependent variable. Furthermore, assessment data is processed by the descriptive analysis of the building, while the questionnaire survey data processed by path analysis using linear regression with SPSS ver. 22. The results of assessment of 14 buildings is a market average of 78 of the highest value of 100, this means that the condition of the building is being with only minor damage. The total yield of the influence of the condition of the building (42.38%) and maintenance resources (25.01%) towards satisfaction of a user through maintenance management (1.26%) is 68.65%.
Industri lift, escalator dan moving walk merupakan bagian yang sulit dilepaskan dari industri konstruksi. Industri ini telah menciptakan alat transportasi yang dibutuhkan manusia untuk melakukan perjalanan di dalam suatu bangunan. Perencanaan kebutuhan lift yang baik perlu dilakukan sejak awal perencanaan suatu bangunan. Hal ini dilakukan agar tidak terjadi antrian yang panjang dalam suatu gedung. Salah satu cara yang dapat dilakukan adalah dengan melakukani koordinasi dengan beberapa pihak yang ahli dibidangnya seperti supplier lift, untuk mendapatkan hasil perencanaan yang sesuai standar SNI 03-6573-2001. Optimasi perencanaan spesifikasi lift yang dilakukan menggunakan Traffic Vision System telah mempertimbangkan faktor-faktor yang paling berpengaruh terhadap traffic pada suatu bangunan seperti luas bangunan, faktor kekosongan, populasi atau kapasitas penghuni gedung, fungsi gedung, fungsi lift dan beberapa faktor lainnya. Berdasarkan hasil optimasi yang dilakukan terhadap 10 data perencanaan lift penumpang pada bangunan perkantoran di Jakarta, optimasi ini berpengaruh terhadap kuantitas, kapasitas, dan kecepatan lift pada saat melaksanakan perencanaan lift. Penghematan rata-rata yang didapatkan sebesar 5,01% terhadap nilai kontrak suatu proyek dan juga memiliki pengaruh rata-rata 0,37% lebih besar dari perencanaan awal terhadap nilai kontrak suatu proyek. Hal ini menunjukkan bahwa perencanaan awal ke 10 data lift penumpang yang diselidiki termasuk kedalam kategori over specification.Kata kunci: Perencanaan kebutuhan lift, Traffic Vision System, penghematan
ABSTRAKIndustri konstruksi untuk bangunan industri khususnya industri MIGAS sangat rentan terhadap risiko ketidakpastian karena sifat bisnisnya dari penilaian investasi awal proyek sampai dengan penyelesaian fisik diakhir proyek. Dan juga sangat rentan terhadap bahaya jika tidak ada langkah langkah yang tepat dan tindakan pencegahan yang diambil, terutama dalam mengelola risiko dan ketidakpastian. Manajemen risiko memastikan bawah risiko dapat diidentifikasi, diperiksa dan dimitigasi dimana para stakeholder sebagai kunci dalam setiap pengambilan keputusan. Penerapan manajemen risiko dalam suatu proyek sangat diperlukan agar tingkat keberhasilannya tinggi dan menghasilkan keuntungan yang tinggi pada tim proyek. Pada penelitian ini dilakukan studi risiko dan biaya dengan mengidentifikasi, mengevaluasi terhadap laporan HAZOP studi terhadap dampak biaya. Analisis risiko dan biaya dievaluasi dengan menggunakan metode simulasi Monte Carlo dengan bantuan perangkat lunak Crystall Ball Versi 11.1.2.3 untuk menentukan konsekuensi risiko dan biaya apa saja yang paling signifikan dalam suatu sistim pada instalasi produksi dan kelayakan suatu proyek untuk dapat dilanjutkan pada tahap konstruksi. Studi Risiko dan biaya pada tahap FEED (perencanaan awal) dengan mengevaluasi laporan HAZOP dilakukan dengan teknik probabilitas menggunakan bantuan software crystal ball Ver.11.1. Dari hasil simulasi pada tingkat keyakinan 90% diperoleh nilai rentang risiko yang masuk dalam kategori Low (rendah) berdasarkan spesifikasi ring rangking dari pihak OWNER. Sedangkan estimasi biaya proyek berdasarkan standar AACE pada tingkat keyakinan 90% masih berada dalam pada rentang nilai biaya tersebut.

And it is also very vulnerable to danger if there are no appropriate steps and precautions taken, especially in managing risks and uncertainties. Risk management ensures that risks can be identified, examined and mitigated by which stakeholders are key in every decision making. The application of risk management in a project is very necessary so that the success rate is high and produces high profits on the project team. In this research, a risk and cost study is carried out by identifying, evaluating the HAZOP study report on the impact of costs. Risk and cost analysis is evaluated using the Monte Carlo simulation method with the help of the Crystall Ball software Version 11.1.2.3 to determine the consequences of the most significant risks and costs in a system at a production plant and the feasibility of a project to proceed at the construction stage. Risk and cost studies at the FEED (initial planning) stage by evaluating the HAZOP report were carried out using probability techniques using...
This paper introduces a method of value engineering analysis by calculating the value coefficient of the substructure work in an office building project. Value coefficient is obtained by dividing the performance coefficient with cost coefficient, whose result shows that the retaining wall system is the main object to be developed. The retaining wall system used in the initial design is soldier pile consisting of rows of 80 cm diameter bored pile with a one-meter center to center spacing, which in each gap between two adjacent bored piles, a 40 cm diameter bentonite pile was constructed. The construction cost of the substructure generated from the initial design is Rp. 35,554,793,500.00. After implementing VE analysis, the VE team chose spun piles with 60 cm diameter (without bentonite piles) with 70 cm center to center spacing as a substitute for the initial design. The assessment performed by the VE team about the performance of the alternative indicates that there is 20.6% increase of performance compared to initial design and cost savings of 17.75%, resulting in a value coefficient of 1.22, this result is 47% higher than the initial design has, which is 0.83.
