Abstract

Industri konstruksi merupakan salah satu sektor penting dalam perekonomian suatu negara. Sektor ini berperan dalam pembangunan infrastruktur, sarana dan prasarana, serta berbagai fasilitas umum lainnya. Dalam pelaksanaannya, proyek konstruksi sering kali mengalami pembengkakan biaya (cost overrun). Cost overrun adalah perbedaan antara biaya aktual yang dikeluarkan dalam pelaksanaan proyek dengan biaya yang telah direncanakan sebelumnya. Cost overrun merupakan hal dapat yang terjadi pada proyek konstruksi di seluruh dunia dan hal ini menyebabkan kerugian ekonomi. Dengan kata lain, pembengkakan biaya telah menjadi tantangan dalam mencapai keberhasilan konstruksi proyek. Penelitian ini merupakan studi kasus dari proyek Gedung sekolah dan gedung mess, dengan menggunakan metode wawancara dan perbandingan data RAP dan RAB. Dengan membandingkan RAB dan RAP dapat mengetahui jenis pekerjaan apa saja yang terjadi cost overrun dan menggunakan metode wawancara dapat diketahui faktor faktor apa saja yang menjadi penyebab utama cost overrun pada jenis pekerjaan tersebut. Hasil penelitian ini diharapkan memberi kesadaran tentang cost overrun pada proyek sehingga dapat meminimalisir terjadinya cost overrun.

Abstract

As an area develops, developments in all areas of construction become increasingly widespread, including the construction/improvement of road construction. In the implementation of construction projects, problems often occur, one of which is that there is still a lot of remaining material that is wasted and will cause waste (Lestari, 2022). This research aims to identify and categorize the types of materials that cause waste in road construction, as well as evaluate the percentage, causes and impact of waste on project losses. Quantitative methods are used to obtain the percentage of waste on projects using data on material type, installation volume, purchase volume and total material costs. Then the data is processed using multiple regression analysis which will be simulated in SPSS. The analysis results indicate that the types of materials most frequently contributing to waste in rigid pavement road construction/improvement projects are as follows: X1 ready-mix concrete 10.99%, X2 wiremesh iron 6.73%, X3 dowel iron 11.81%, and X4 plastic 5.11%. The sources causing the generation of waste materials include design, implementation, material procurement/handling, and residuals. Assessing the impact of waste materials on losses in road construction projects using SPSS multiple linear regression, the project loss variable is derived as Y = -711.522 + 0.749 X1 + 60.096 X3. This implies that the materials significantly affecting project losses are X1 ready-mix concrete and X3 dowel iron. The magnitude of the influence of independent variables (ready-mix concrete and dowel iron) on project losses is 58.80%. The results of this research have implications in preventing losses from road construction projects in DKI Jakarta.

Abstract

The construction of buildings generally uses reinforced concrete, concrete has varying strengths from fc'35, fc' 45, etc. The compressive strength of concrete also has varying prices, the higher the quality, the more expensive it is. Before carrying out construction, it is important to calculate the RAB because with the RAB we can find out the budget that will be spent and which construction method is more effective. This study conducted using a comparative analysis method where the author compared the price of casting using high quality concrete with different concrete qualities, the resulting price will be a comparative material for casting with high quality concrete or casting with different qualities that are more effective. This study conducted to determine how much cost efficiency can be obtained by using different concrete qualities. The cost efficiency obtained by using different concrete qualities is ±9.82%. if construction uses different concrete qualities. It found that casting with high concrete quality is Rp. 21,989,341,942.77. If the casting uses different concrete quality, the price obtained is Rp19,829,336,609.91, then the cost savings obtained are Rp2,160,005,332.86. The results of the project analysis will be more efficient with the use of different concrete quality resulting in a cheaper price. Abstrak Pembangunan gedung umum menggunakan beton bertulang, beton memiliki kekuatan yang beragam dari fc’35, fc’ 45, dll. Kuat tekan beton juga memiliki harga yang bervariasi semakin tinggi mutu nya semakin mahal harga nya. Sebelum melakukan pembangunan sangatlah penting untuk melakukan perhitungan RAB karena dengan ada nya RAB kita dapat mengetahui anggaran biaya yang akan di keluarkan dan metode pembangunan mana yang lebih efektif. Penelitian ini di lakukan dengan menggunakan metode analisis komparatif di mana penulis melakukan perbandingan harga pengecoran dengan menggunakan mutu beton tinggi dengan mutu beton berbeda harga yang di hasilkan akan menjadi bahan perbandingan pengecoran dengan beton mutu tinggi atau pengecoran dengan mutu berbeda yang lebih efektif. Penelitian ini di lakukan untuk mengetahui seberapa besar efesiensi biaya yang dapat di peroleh dengan penggunaan mutu beton berbeda. Efesiensi biaya yang didapatkan dengan menggunakan mutu beton berbeda sebesar ±9,82%.bila pembangunan menggunakan mutu beton berbeda.

Abstract

The implementation of program management in megaprojects often encounters a gap between strategic planning and field execution. This study evaluates stakeholder perceptions regarding the effectiveness of program implementation and project performance in Indonesia’s Nusantara Capital City (IKN). A quantitative survey was conducted with 200 respondents divided into two infrastructure typologies: Horizontal (roads, area development, water resources) and Vertical (high-rise and low-rise buildings). A 6-point Likert scale questionnaire measured six variables: benefit tracking (X1), resource allocation (X2), coordination (X3), risk management (X4), program implementation (M1), and project performance (Y1). The data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) and multigroup analysis. In Horizontal projects, coordination emerged as the dominant factor (X3→M1 = 0.546; p = 0.000), with program implementation significantly affecting project performance (M1→Y1 = 0.413; p = 0.000). In Vertical projects, risk management was key (X4→M1 = 0.302; X4→Y1 = 0.412; p = 0.000). The strongest indirect effect was found in the coordination-to-performance path through program implementation (0.259; p = 0.000). R² values indicate strong predictive power for program implementation (Horizontal = 0.617; Vertical = 0.660) and project performance (Horizontal = 0.680; Vertical = 0.597). These findings highlight the importance of context-specific program governance strategies.

Abstract

A significant proportion of existing buildings in Indonesia were constructed prior to the adoption of modern seismic design standards, resulting in a high level of vulnerability to earthquakes. This poses a serious threat to occupant safety and the continuity of building functionality during seismic events. This study aims to evaluate retrofitting strategies using the ASCE 41-17 approach to enhance the seismic resilience of existing structures. A total of eight buildings in the Jakarta area were analyzed using the Tier 1 checklist to identify structural vulnerabilities. Based on field inspections, retrofit methods such as the addition of structural elements, column jacketing, expansion joints, and detailed structural surveys were proposed. Cost estimates were prepared through a Bill of Quantities (BOQ) and evaluated using a Benefit-Cost Analysis approach. The results indicate that most retrofit methods yield benefit-cost ratios significantly greater than 1, suggesting that the benefits of improved seismic performance outweigh the associated costs. This study provides practical and effective retrofit recommendations, which can serve as a reference for policymakers, building owners, and civil engineering practitioners in planning structural strengthening of existing buildings in earthquake-prone areas. Abstrak Sebagian besar bangunan eksisting di Indonesia dibangun sebelum adopsi standar desain seismik yang mutakhir, sehingga memiliki tingkat kerentanan tinggi terhadap gempa bumi. Kondisi ini menjadi ancaman serius bagi keselamatan penghuni dan keberlanjutan fungsi bangunan saat bencana terjadi. Penelitian ini bertujuan mengevaluasi strategi retrofitting menggunakan pendekatan ASCE 41-17 untuk meningkatkan ketahanan seismik bangunan eksisting. Sebanyak 8 bangunan di wilayah Jakarta dianalisis menggunakan checklist Tier 1 untuk mengidentifikasi kerentanan struktural. Berdasarkan hasil inspeksi lapangan, ditentukan metode retrofit seperti penambahan elemen struktur, jacketing, sambungan dilatasi, dan survei detail struktur. Estimasi biaya disusun melalui Rencana Anggaran Biaya (RAB) dan dianalisis menggunakan pendekatan Analisis Biaya-Manfaat. Hasil menunjukkan sebagian besar metode retrofit memiliki nilai signifikan di atas 1, menandakan bahwa manfaat yang diperoleh dari peningkatan ketahanan terhadap gempa melebihi biaya yang diperlukan. Penelitian ini memberikan rekomendasi solusi retrofit yang layak dan efektif, serta dapat dijadikan acuan bagi pemangku kebijakan, pemilik bangunan, maupun praktisi teknik sipil dalam merencanakan penguatan struktur bangunan eksisting di wilayah rawan gempa.

Abstract

The Nusantara Capital City (IKN) development project is one of the strategic megaprojects in Indonesia with the aim of moving the center of government to East Kalimantan. The megaproject faces a number of significant challenges, including delays in physical progress, budget constraints, constraints in land acquisition, and complex technical risks. This study aims to analyze the challenges and risk mitigation strategies implemented in the IKN project through a qualitative approach based on progress reports until September 2024. With thematic analysis using the NVivo tool, three main themes in risk mitigation were found, namely flexible financial management, the use of Building Information Modeling (BIM) technology, and a cross-sector collaborative approach. The use of BIM has proven to be effective in detecting design clash detection, which reduces technical risks in the field. In addition, the involvement of local governments and local communities in the land acquisition process accelerates negotiations and reduces the potential for social conflict. The results of this study show that cross-sector collaboration, technology integration, and adaptive budget management play an important role in ensuring the smooth running of large-scale projects. This study is expected to contribute to the development of risk management strategies in Indonesian infrastructure projects.

Abstract

Occupational accidents are a problem in Occupational Health and Safety (OHS) activities in a job, especially construction. Accidents that occur can provide losses both in terms of workers and companies. Such as workers who are hit by material that can cause injury so they have to undergo hospitalization and disrupted work time. Things like this can cause losses in terms of time, cost, and performance of a job. This analysis focuses on workers and identifies the factors that cause accidents that are often experienced by workers so that the factors that are most at risk of causing accidents during work activities can be identified. The research will be conducted by direct interviews and distributing questionnaires to workers at the Mandiri Bumi Slipi IT Project. The risk assessment method uses a risk assessment matrix that originates from Standard Operational Procedures for Hazard Identification, Risk Assessment, Determination of Risk Control and Opportunities (SOP/UPM/DJBM-149). The results obtained from processing the risk value data from the formwork, reinforcement and curtain wall work categories belong to the small to medium risk level with the smallest value of 2 and the highest moderate risk level of 6. Abstrak Kecelakaan kerja merupakan suatu permasalahan dalam kegiatan Kesehatan dan keselamatan Kerja (K3) pada suatu pekerjaan terutama konstruksi.
