<![CDATA[Severe traffic congestions are often in Dewa Ruci Intersection. It leads to the Bali Provincial Government is forced to build an underpass at this intersection. The impact of construction will be add to the congestion becomes more severe that will take it during the project. To overcome, it is necessary to make the comparative method that have already used (secant pile) with precast method (sheet pile) is known relatively quickly and cheaply. However, this comparison should be followed up with a risk analysis that will happen with these methods. The results showed that sheet pile can accelerate 13.58 days or 5.21% and reduce Rp. 2,754,284,040.00 or 14.47% of secant pile method. The construction cost risk level of sheet pile is almost equal to secant pile but the construction time risk level of sheet pile is smaller than the secant pile.]]>

<![CDATA[Multiyear construction project is one of the riskiest project due to uncertainty and dynamic economic condition. In multi-years project, cost escalation is inevitable because during construction period various risk factors such as increasing of labor cost, materials cost, energy cost, and equipment cost will affect the costs of the projects. This paper proposes a model to estimate cost escalation based on System Dynamic (SD) approach. SD is used to represent correlation among risk factors influencing cost escalation and to calculate cost escalation during project period. Causal Loop Diagram (CLD) was made based on in-depth literature review and confirmed by the experts. To validate the model, 7 multi-years projects in Indonesia were used as case study. The result showed that the proposed model can accurately predict project cost escalation with an accuracy of 91.21%. Simulation of SD also showed that the change of scope of work, ambiguous contract condition, unpredictable conditions, project schedule delay, inflation, and extreme weather condition are the most influencing factor of cost escalation. Besides predicting cost escalation of project, this model can also be used as early warning system in multi-year projects environment.]]>

<![CDATA[Indonesia is one of the countries prone to earthquakes. One of the earthquake disasters that occurred several years ago hit Palu and Donggala on September 28, 2018. It caused severe damage to infrastructure. Therefore, it is necessary to evaluate buildings vulnerable to earthquakes as a form of prevention. One of the buildings in Jember, the dr. Soebandi hospital, experienced cracks in the walls during an earthquake measuring 6.0 on the Richter scale in Nusa Dua Bali on July 16, 2019. This study carried out the risk assessment of the vulnerability of buildings to earthquakes using the Rapid Visual Screening (RVS) method from FEMA P-154. RVS is a method to identify a building that is potentially vulnerable to earthquake hazards based on visual observations from the exterior and interior of the building. The results of the evaluation using the RVS method showed that the dr. Soebandi hospital is categorized as safe and not prone to earthquakes, with a potential vulnerability percentage of 0.0126%. Based on these results, the building does not require special treatment to anticipate earthquakes; however, maintaining the occupants' safety and extending the building's life requires routine maintenance. ]]>

<![CDATA[Kecelakaan kerja di sektor konstruksi masih mendominasi dibanding industri lain. Hal ini berdampak terhadap program pemerintah dalam mewujudkan SDGs bidang ketenagakerjaan. Berbagai penelitian tentang K3 sudah dilakukan tetapi masih memiliki kelemahan yang harus disempurnakan agar dapat membantu menyelesaikan permasalahan K3. Salah satu metode yang diharapkan mampu menyelesaikan permasalahan ini adalah metode Fault Tree Analysis (FTA) karena metode ini selain dapat menentukan faktor penyebab kecelakaan juga dapat memperkirakan probabilitas kejadiannya. Pada penelitian ini menggunakan metode wawancara dan pengamatan serta pencatatan data K3 pada proyek konstruksi pekerjaan jalan. Variabel yang digunakan diperoleh dari studi literatur dan Job Safety Analysis (JSA) yang dikonfirmasi kepada responden serta hasil pengamatan di lapangan yaitu faktor manajemen K3, unsafe condition, dan unsafe action. Metode FTA berhasil memprediksi probabilitas kegagalan pelaksanaan K3 pada proyek tersebut sebesar 0.3323 dengan kontribusi terbesar diperoleh dari variabel unsafe condition diikuti faktor manajemen K3 dan unsafe action. Untuk membuktikan keandalan model ini dilakukan validasi terhadap luaran model FTA dengan mendeskripsikan data kecelakaan yang terekam baik kuantitas maupun kategorinya. Untuk mencari besaran kontribusi setiap variabel dilakukan skenario model dan diperoleh hasil bahwa unsafe condition memiliki kontribusi terbesar diikuti manajemen K3 dan unsafe action dengan nilai masing-masing 0.0624, 0.0593 dan 0.0468. Model FTA juga dapat dikembangkan menjadi konsep DSS dengan syarat dan ketentuan tertentu.]]>

<![CDATA[Settling of Tower Crane (TC) will influence efficiency of task served, it will effect to leasing cost and operational cost of TC. This problem is gotten by contractors while they arrange construction schedule. TC’s placement isn’t exact that due to extend scheduling and cost wasteful. Therefore, TC’s settling needs a calculation of TC workload balance in order to minimize duration time. To field observation will be taken an ongoing construction project which is Jember Icon’s Project on Gajah Mada street in Jember. Results of these researches shown exactly settling of TC will reduce operational hours and project schedule. Penempatan Tower Crane (TC) akan mempengaruhi efisiensi pekerjaan yang dilayani, hal ini juga akan berpengaruh pada biaya sewa dan biaya operasional TC. Permasalahan ini sering dihadapi oleh kontraktor ketika menyusun rencana pelaksanaan kegiatan proyek. Penempatan TC yang tidak tepat dapat mengakibatkan jadwal pelaksanaan yang panjang dan pemborosan biaya. Oleh karena itu dalam penempatan TC memerlukan perhitungan keseimbangan beban kerja TC agar dapat meminimalisasi durasi penggunaan TC. Observasi lapangan dilakukan pada proyek konstruksi yang sedang berjalan yaitu pada proyek Jember Icon, yang berlokasi di Jalan Gajah Mada, Jember. Hasil penelitian menunjukkan penempatan TC dapat diketahui bahwa penempatan TC yang tepat dapat mereduksi jam operasional TC dan jadwal proyek.]]>

<![CDATA[Proyek Apartemen Grand Shamaya Surabaya merupakan salah satu proyek gedung tinggi di Surabaya yang dibangun di atas lahan yang memiliki kondisi tanah yang buruk dan sempit serta berada di antara gedung tinggi yang berdekatan. Pada pekerjaan basemen gedung ini memerlukan metode pelaksanaan yang tepat karena metode pelaksanaan ini sangat berpengaruh terhadap ketercapaian tujuan proyek (biaya, mutu dan waktu). Oleh karena itu perlu adanya analisa yang mendalam dengan mempertimbangkan semua variabel yang berpengaruh dalam penentuan metode konstruksi. Salah satu metode yang dapat diaplikasikan untuk membantu dalam pengambilan keputusan metode konstruksi yang tepat adalah Metode Analytical Hierarchy Process (AHP). Metode ini memiliki kemampuan dalam menyusun skala prioritas (sebagai faktor bobot) dari variabel yang kompleks dan mudah diaplikasikan, sehingga metode ini dapat dijadikan alat untuk pengambilan keputusan penentuan metode konstruksi yang mudah dan cepat. Pengambilan data dilakukan melalui kuisioner dan indepth interview dengan responden yang memiliki kepakaran (pengetahuan, pengalaman, dan keterampilan yang baik dalam penyusunan metode konstruksi). Hasil penelitian menunjukkan bahwa metode AHP ini dapat disusun sebagai sistem pengambilan keputusan penentuan metode konstruksi pekerjaan basement dengan tepat. Bobot prioritas yang dihasilkan dari AHP dapat dijadikan parameter untuk menentukan nilai keputusan penentuan metode konstruksi berdasarkan ketersediaan sumber daya yang dimiliki pada proyek tersebut.]]>

<![CDATA[In the implementation of project development, problems often occur which cause the project to get obstacles, causing delays in project completion time and failure to achieve the project goals. Therefore, it is necessary to research risk analysis and effectively mitigate it to reduce the negative impact of delays. Currently, many studies analyze the risk of delays but are limited to risk assessment based on probability and impact, and mitigation is only carried out on the causal variables without paying attention to the agent of the delay. While in this study using the House of Risk (HOR) method which consists of 2 stages. The first stage (HOR-1) is to determine the main factors causing delays and the second stage (HOR-2) is to mitigate risk effectively to properly resolve the delay problem based on the delay agent. The results of the delay risk analysis using HOR obtained 6 delay events caused by 7 dominant agents/causes of delay based on the Pareto diagram. Recommendations for handling project delays that are effective can be carried out through 4 main mitigation efforts so that the impact of delays can be prevented or reduced.]]>
