Abstract

ABSTRAK Pemindahan ibu kota negara ke kawasan Ibu Kota Nusantara (IKN) merupakan proyek pembangunan strategis nasional yang memiliki tingkat kompleksitas konstruksi tinggi serta target waktu pelaksanaan yang ketat, khususnya pada pembangunan bangunan Istana dan Kantor Wakil Presiden. Kondisi tersebut menuntut penerapan metode pelaksanaan yang efektif dan efisien untuk menjamin pencapaian target mutu, waktu, dan biaya. Penelitian ini bertujuan menganalisis penerapan re-engineering pada pekerjaan struktur beton, khususnya pekerjaan plat lantai, melalui evaluasi metode pengecoran dan bekisting. Penelitian menggunakan pendekatan kuantitatif dengan tahapan re-engineering yang meliputi tahap informasi, kreatif, analisis, dan rekomendasi. Identifikasi pekerjaan kritis dilakukan menggunakan Breakdown Cost Model dan analisis Pareto, sedangkan evaluasi alternatif metode dilakukan melalui analisis waktu–biaya berdasarkan Rencana Anggaran Biaya (RAB), analisis harga satuan pekerjaan, serta perbandingan durasi pelaksanaan. Hasil penelitian menunjukkan bahwa kombinasi metode bekisting sistem dan beton ready mix dengan concrete pump yang ditambahkan aditif superplasticizer Sika Viscocrete 8007 merupakan alternatif paling optimal. Penerapan metode tersebut mampu mengurangi durasi pekerjaan sebesar 66 hari dibanding metode eksisting serta menghasilkan efisiensi biaya sebesar Rp327.419.470,00 tanpa menurunkan mutu pekerjaan. Temuan ini menunjukkan bahwa penerapan re-engineering metode konstruksi dapat meningkatkan efisiensi pelaksanaan proyek infrastruktur pemerintahan dan mendukung percepatan pembangunan kawasan inti pemerintahan secara lebih efektif.Kata Kunci: Ibu Kota Nusantara (IKN), percepatan pekerjaan, metode kerja beton, ready mix concrete, superplasticizer, bekisting semi sistem. ABSTRACT The relocation of Indonesia’s capital city to the Nusantara Capital City (IKN) represents a strategic national development project characterized by high construction complexity and strict completion targets, particularly in the construction of the State Palace and the Vice Presidential Office buildings. These conditions require effective and efficient construction methods to ensure the achievement of quality, time, and cost targets. This study aims to analyze the implementation of re-engineering in concrete structural works, specifically floor slab construction, through the evaluation of casting and formwork methods. The research employs a quantitative approach using re-engineering stages consisting of information, creative, analysis, and recommendation phases. Critical work items were identified using the Breakdown Cost Model and Pareto analysis, while alternative methods were evaluated through time–cost analysis based on the Bill of Quantities (BOQ), unit price analysis, and schedule comparison. The results indicate that the combination of system formwork and ready-mix concrete using a concrete pump with the addition of the superplasticizer Sika Viscocrete 8007 is the most optimal alternative method. The implementation of this method reduces project duration by 66 days and achieves cost efficiency of IDR 327,419,470 compared to the existing method without compromising construction quality. These findings demonstrate that the application of construction method re-engineering can significantly improve project efficiency and support the acceleration of government infrastructure development within the core administrative area.Keywords:Nusantara Capital (IKN), construction acceleration, concrete work methods, ready-mix concrete, superplasticizer, semi-system formwork.

Abstract

ABSTRACTThe provision of vertical housing in developing cities such as Tegal faces challenges not only in construction but also in sustaining building functionality and maintenance over time. The feasibility of public rental housing (Rusunawa) constitutes a critical component of urban housing asset management to ensure safety, comfort, and service sustainability for low-income residents. This study aims to assess the feasibility level of Block B of Kraton Rusunawa within a framework that integrates technical evaluation and occupants’ perceptions. A descriptive quantitative approach was employed through checklist-based observations in accordance with the Regulation of the Ministry of Public Works and Housing (Permen PUPR No. 22/2018), combined with user assessments. The evaluation covered three main aspects: structure (45%), architecture (35%), and utilities (20%), using a 1–4 rating scale. The results indicate that all floors fall into the conditionally feasible category, with scores ranging from 1.61 to 2.12. A disparity in building conditions across floors was identified, with the fourth and fifth floors exhibiting higher levels of degradation compared to the lower floors, thereby requiring priority maintenance. These findings highlight the importance of preventive maintenance strategies and periodic rehabilitation scheduling as part of Rusunawa asset management. From a policy perspective, the study provides an evaluative basis for local governments in planning maintenance programs and allocating housing budgets within the framework to ensure the long-term sustainability of vertical housing.Keywords: Building Feasibility, Vertical Housing, Public Housing Maintenance, Urban Asset Management, Technical EvaluationABSTRAKPenyediaan hunian vertikal di kota sedang berkembang seperti Kota Tegal menghadapi tantangan tidak hanya pada pembangunan, tetapi juga pada keberlanjutan fungsi dan pemeliharaan bangunan.

Abstract

Risk management in the form of initial mitigation by considering internal and external factors and issues will be able to narrow the gap in making predictions and strategies to accelerate the completion time of work until it is completely completed. The Loji-Banger River Flood and Robo Control Project Package 1 is one of the government's strategic projects which aims to overcome tidal floods on the north coast of Pekalongan City. Risk assessment is carried out in several stages from risk identification to mitigation suggestions to reduce the scale of risk from inherent risk to residual risk which shows that of the 35 variables assessed, all risk factors have decreased on the risk scale, however there are several risk factors that are of particular concern. because the residual risk is still at a moderate level, so very tight controls or control are needed because it could potentially cause a gap in the work acceleration target time, including possible risks due to delays in material delivery (X2), possible risks due to some of the work land not being free (X11 ), possible risks due to the DIPA Budget Refocusing Issue, its influence on cash flow (X18), possible risks due to the influence of the company's financial condition on the project action plan (X19), possible risks due to errors in preparing work sequences or work zoning (X27).

Abstract

The construction of the Simpang Joglo Elevated Track Bridge is an iconic development in the city of Surakarta with the Elevated Railway Bridge which was built over seven very busy intersections. At this intersection, traffic jams often occur when trains pass, for this reason an elevated track railway bridge was built to reduce this congestion. The implementation of development is not free from risks that occur both internally and externally. This research aims to identify the risks and problems that occur in the construction of the Simpang Joglo Elevated Track Bridge. After identification, an assessment will be carried out on the level of risk that has been identified in the construction of the elevated track bridge at Joglo intersection. Data collection was divided into two, namely primary data collection through distributing questionnaires and interviews on the Simpang Joglo Elevated Track Bridge Construction Project which was conducted with project owners, consultants and contractors and secondary data collection through previous research and data from the Simpang Joglo Elevated Track Bridge Construction Project. Risk identification is carried out using the Risk Breakdown Structure (RBS) method and probability impact grid to determine the level of risk. After obtaining the data, a feasibility test will be carried out on respondents and then a validity and reliability test will be carried out for the three stakeholders. Risk identification is carried out by calculating the probability and impact for each variable and then clarifying the ranking using the Extremely Ineffective, Ineffective, Moderately Ineffective, Very Effective and Extremely Effective rating scale. After that, the risk level is classified using a probability-impact matrix. From the results of the risk level classification, it was found that there were 31 risk variables in the high category from the owner, 31 risk variables according to the consultant and 19 risk variables according to the contractor. Determining the high category of risk is based on combining the same variables from the three stakeholders to obtain 18 risk variables. These variables are problems that occur and influence the implementation of the Simpang Joglo Elevated Track Bridge Construction Project. These problems include increased vibration, traffic flow, road damage, K3 environmental sanitation, community attitudes and perceptions, organizational structure, payments, owner finances, overtime, time and cost estimates, changes in design, heavy equipment and materials

Abstract

This paper presents research on anticipation and solutions for equipment cost overruns on toll road construction projects in Jabodetabek. A survey was conducted with 76 respondents (Managers, Consultants, Contractors). The dominant factor causing equipment cost overrun is breakdown of heavy equipment (mean = 4.32), followed by delay in mobilization (mean = 4.18). Preventive maintenance schedules and contractual penalty clauses are established as key solutions.
