Pemakaian Tower Crane (TC) seringkali terkait oleh mahalnya biaya sewa
dan biaya operasionalnya. Ada pun penempatan TC yang kurang tepat dan dapat
berakibat kurang efisiennya pekerjaan yang dilakukan. Hal ini merupakan masalah
yang dihadapi oleh kontraktor dan mempengaruhi efesiensi penggunaan TC terhadap
jadwal proyek yang beresiko akan terjadinya pemborosan biaya pada penggunaan TC.
Maka dari itu diperlukan suatu perhitungan keseimbangan beban kerja TC serta
perbaikan penempatan TC itu sendiri dimana upaya tersebut dapat meminimalisasi
durasi penggunaan pada setiap aktivitas proyeknya.
Metode dalam penelitian ini dilakukan dengan cara observasi lapangan
dilakukan pada proyek konstruksi yang sedang dalam pembangunan pada proyek
Jember Icon, yang berlokasi di Jalan Gajah Mada, Jember. Dari hasil observasi
akan diketahui jadwal pemakaian TC dan aktivitas-aktivitas yang menggunakan
TC. Tahapan analisis diawali dengan pembagian daerah tujuan material dan
memastikan seluruh lokasi penempatan tower crane yang memungkinkan. Dengan
menggunakan metode try and error, didapatkan output alternatif lokasi tower crane.
Perbaikan penempatan TC akan dianalisis berdasarkan total waktu siklus dan
keseimbangan beban kerja pengangkutan material dalam tahap pekerjaan yang
ditinjau.
Hasil dari penelitian ini adalah total waktu pekerjaan dan keseimbangan beban
kerja yang lebih kecil nilainya dari lokasi TC sebelumnya. Lokasi TC1 yang semula
mempunyai koordinat di (64,778; 3,9119), TC2 di (103,38; 99,32), dan TC3 di
(21,281; 91,886) lalu diperbaharui menjadi TC1 di (38,303; 41,934), TC2 di (87, 681;
40, 794), dan TC3 di (99,856; 99,586) dapat menekan nilai keseimbangan beban kerja
viii
(σ) menjadi lebih kecil yaitu sebesar 127,94 menit dari lokasi TC yang sebelumnya
yaitu 156,2 menit. Total waktu kerja seluruh TC terminimalisir dari 10526 menit
menjadi 9721.3 menit dengan rata-rata waktu setiap pekerjaan yang semula 3509
menit menjadi 3240,4 menit. Di samping itu, hanya pekerjaan beton saja yang dapat
dihitung selisih waktunya terhadap pekerjaan per lantai karena titik supply beton
berada di luar bangunan. Didapatkan rata-rata selisih waktu per lantai adalah 0,39238
menit. Selanjutnya dapat disimpulkan bahwa lokasi TC yang baru adalah optimum

A System Dynamics Approach to Optimizing Building Design for Constructability and Maintainability
Get PDFMany projects in Indonesia experience delays and budget overruns due to designs that do not align with field implementation and project cycles. This study introduces a System Dynamics (SD) approach as a breakthrough for modeling the complex, dynamic relationships among Design, Constructability, and Maintainability factors in building projects. The research's novelty lies in applying holistic, predictive dynamic simulation modeling to quantify the interplay among variables that have previously been analyzed only partially. Simulation results reveal that social, economic, and environmental aspects significantly influence design. A maintainability-focused strategy increases the Maintainability Index to 1.00, but reduces Constructability to 0.50. Conversely, prioritizing Constructability raises the Constructability Index to 1.00, while decreasing Maintainability by 30% (0.70). A hybrid scenario yields moderate improvements (Constructability 0.80, Maintainability 0.70), confirming that partial optimization results in suboptimal system performance. The implementation prospects are robust for the Indonesian construction industry. This model provides a quantitative basis for encouraging best practices such as early contractor and supplier involvement and more strategic integration of Building Information Modeling (BIM). Scenario simulations demonstrate that a balanced optimization strategy is significantly superior to a partial approach. Stakeholders can adopt these findings as a decision-making tool to allocate resources more effectively, improve construction efficiency, and ensure the long-term sustainability of building performance, thereby accelerating sustainable infrastructure development.

Get PDFThe implementation of physical work requires good project control because various conditions can affect the construction implementation process. The calculation of performance analysis is carried out with Earned Value Management (EVM) and the determination of project completion time is carried out by the CPM-PERT method. In this research, it was found that in the 26th week, the schedule performance index value was 0.75758 with an estimated project completion time using the EVM method of 242 days. The critical path shown by the CPM method is M - G - H - N - F - D - E - P - O - K - B – A with a total project completion time of 274 days. Based on the PERT method, the probability of completion time for the project is 71.90%. Acceleration is carried out using the CPM critical path with an optimistic duration of PERT. This acceleration can be done by optimizing the project completion time to 256 days
Evaluation of Building Vulnerability to Earthquake Using Rapid Visual Screening (RVS) Method
Get PDFIndonesia 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
