Abstract

Kecepatan aliran bidang vertikal di lahan gambut memiliki karakteristik unik dan berbeda dengan sungai, yang dipengaruhi oleh topografi, morfologi, dan hidrometri saluran. Penelitian ini bertujuan untuk menganalisis profil distribusi kecepatan aliran bidang vertikal dan kecepatan aliran rerata yang dilakukan pada 2 saluran dengan variasi lebar dan kedalaman. Pengukuran kecepatan dilakukan pada potongan melintang yang dibagi menjadi 7 rai (B/2, B/4, B/8, B/16) pada kiri dan kanan serta tengah, dimana (B) adalah lebar saluran. Pada setiap rai, kecepatan diukur pada sepuluh titik kedalaman dengan pengulangan 5 hingga 16 kali. Hasilnya menunjukkan pola distribusi kecepatan yang sama pada beberapa rai di kedua saluran, khususnya (B/2 di tengah, B/4 kiri, B/8 kiri, B/4 kanan, dan B/8 kanan). Pada rai ini, kecepatan besar di permukaan dan menurun mendekati dasar. Namun, di tepi saluran 1 (B/16 kiri, B/8 kanan), saluran 2 (B/16 kanan), pola distribusi menunjukkan kecepatan aliran bertambah besar di dasar saluran. Rerata kecepatan aliran mencapai 0,041 m/dt di saluran 1 (B/16 kanan) dan 0,048 m/dt di saluran 2 (B/2 tengah), dengan kedalaman rerata 0,4 sampai 0,6 h. Hal ini disebabkan pada lahan gambut terdapat akar dan serat, membentuk pori-pori yang mempercepat pergerakan aliran air tanah menuju saluran khususnya bagian tepi.

Abstract

Menurut AISC, kekuatan batas leleh lokal badan pada balok WF yang diakibatkan beban terpusat, dipengaruhi oleh panjang tumpu N dari pelat landasan, bukan lebar B. Beban terpusat tersebut didistribusikan ke badan balok dengan asumsi kemiringan sebesar 1: 2.5. Penelitian ini bertujuan untuk meninjau kemungkinan lebar pelat landasan B berpengaruh terhadap peningkatan kekuatan leleh lokal badan, serta asumsi kemiringan distribusi beban 1: 2.5 dapat dioptimalkan lebih lanjut. Metode penelitian dilakukan secara simulasi numerik dengan menggunakan software analisis elemen hingga (FEA), yang memodelkan baja WF di bawah pelat landasan sebagai elemen solid. Hasil FEA menunjukkan bahwa lebar B berpengaruh terhadap kekuatan leleh lokal badan, tetapi tidak signifikan. Distribusi beban juga dapat diusulkan dengan kemiringan 1:3.

Abstract

Bandung merupakan salah satu kota di Indonesia yang sering mengalami kemacetan akibat meningkatnya volume kendaraan dan keterbatasan kapasitas jalan. Salah satu titik rawan kemacetan berada di Bundaran Cibiru, konflik arus kendaraan dari berbagai arah serta desain bundaran yang tidak lagi memadai menyebabkan kepadatan lalu lintas, terutama pada jam sibuk. Untuk mengatasi permasalahan ini, pemerintah mengusulkan pembangunan underpass sebagai simpang tidak sebidang. Penelitian ini mengevaluasi kelayakan ekonomi proyek underpass melalui analisis kinerja lalu lintas dan parameter ekonomi. Analisis lalu lintas membandingkan kondisi eksisting dan simulasi pasca pembangunan dengan meninjau kecepatan rata-rata kendaraan serta tingkat kejenuhan (degree of saturation). Sementara itu, aspek ekonomi dinilai berdasarkan Biaya Operasional Kendaraan (BOK), Nilai Waktu (Time Value), serta perhitungan Benefit Cost Ratio (BCR) dan Net Present Value (NPV). Hasil penelitian menunjukkan nilai BCR sebesar -14 (<1) dan NPV negatif senilai - Rp 16 triliun, yang berarti proyek ini tidak layak secara finansial. Dengan demikian, diperlukan pertimbangan ulang atau alternatif solusi lain untuk mengatasi kemacetan di Bundaran Cibiru.

Abstract

Kinerja balok baja dalam menahan momen lentur dan gaya geser sangat dipengaruhi oleh geometri penampang dan properti materialnya. Dalam perancangan struktur baja, ketidaksempurnaan geometri penampang dalam batas toleransi umumnya tidak diperhitungkan secara eksplisit, meskipun dapat berkontribusi terhadap perubahan perilaku struktur. Penelitian ini bertujuan untuk mengevaluasi dampak ketidaksempurnaan penampang dalam batas toleransi terhadap kekuatan dan kapasitas deformasi lentur serta geser pada balok baja berpenampang sayap lebar. Kajian dilakukan secara numerik menggunakan perangkat lunak elemen hingga pada model balok kantilever dengan panjang yang berbeda untuk merepresentasikan kegagalan dominasi lentur dan geser. Variasi model mencakup enam tipe ketidaksempurnaan berdasarkan standar JIS G3192:2008. Hasil analisis menunjukkan bahwa ketidaksempurnaan penampang yang menghasilkan bentuk asimetris terhadap sumbu lemah (Tipe-1 dan Tipe-2) dapat menurunkan kapasitas rotasi dan daktilitas lentur balok, sehingga tidak dapat digunakan sebagai bagian dari sambungan balok kolom Rangka Momen Khusus sesuai SNI 7860:2020. Selain itu, kedua tipe ketidaksempurnaan ini (Tipe-1 dan Tipe-2) dan ketidaksempurnaan pelat badan web yang tidak lurus (Tipe-6) menurunkan kapasitas deformasi geser balok, hingga 7% di bawah kekuatan geser nominal penampang. Temuan ini mengindikasikan bahwa meskipun berada dalam batas toleransi, ketidaksempurnaan geometri penampang dapat berpengaruh terhadap performa struktur.

Abstract

The growth of educational activities and urban mobility in the Jatinangor area has significantly increased traffic intensity and the risk of pedestrian accidents, particularly along the Bandung–Sumedang Highway. This study aims to evaluate the technical and functional feasibility of constructing a pedestrian bridge (JPO) and to compare it with the alternative of a pelican crossing as a more adaptive pedestrian solution. The research methods include field surveys, analysis of pedestrian behavior and traffic flow, as well as multi-criteria assessments of both alternatives based on safety, cost efficiency, accessibility, and utilization levels. The findings indicate that although the pedestrian bridge meets technical requirements, its effectiveness is limited due to low utilization rates and poor accessibility for vulnerable groups. In contrast, the pelican crossing is considered more suitable for medium-capacity roads with high pedestrian volumes, as it offers greater efficiency, inclusivity, and lower costs. These results support the hypothesis that the pelican crossing provides a more appropriate solution for improving pedestrian safety in the study area, while also offering recommendations for context-sensitive and sustainable traffic infrastructure planning.

Abstract

Productivity in Building Information Modeling (BIM) modeling plays a key role in project efficiency. However, the comparison between precast and traditional methods is still rarely studied. This research investigates the productivity comparison between BIM modeling methods and traditional construction execution on the Rumah Sakit Mitra Pumbon Subang project. The study uses a descriptive quantitative approach with data collected through 3D modeling (Autodesk Revit), scheduling (Microsoft Project), and 4D simulation (Autodesk Navisworks). The results show that BIM modeling requires more time (28 days) compared to the precast method (41 days) due to design complexity and more detailed object modeling in Revit compared to traditional CAD drawings. Meanwhile, the traditional construction method takes longer (153 days) compared to the precast method (137 days), due to the standardization advantages of precast work. In terms of material needs, BIM provides more precise calculations using the "Duplicate with Full Properties" and "Rebar Template Library" features in Revit. In conclusion, BIM modeling takes longer, but offers better precision and physical efficiency. This research emphasizes the importance of selecting the appropriate modeling method for optimal construction performance.

Abstract

Innovations in modern building design encourage the integration of utility systems, such as rainwater drainage, into structural elements to improve space efficiency and aesthetics. This study aims to analyze the effect of embedding PVC (pralon) pipes as internal drainage channels on the strength and efficiency of reinforced concrete columns. A numerical analysis was carried out using the spColumn software on columns with dimensions of 350 × 600 mm, with variations in the number of 4-inch pipes (zero, one, two, and three). The results show that installing one, two, and three pipes gradually reduced the maximum compressive capacity of the column from 4100 kN to 3930 kN, 3790 kN, and 3650 kN, respectively. Despite this reduction, all column configurations were proven to be safe for sustaining the planned ultimate load of 368.72 kN. Interestingly, the structural–material efficiency of the column increased by up to 4.2% in the three-pipe configuration, as the reduction in concrete volume outweighed the decrease in capacity. It is concluded that the integration of PVC drainage pipes into columns offers a structurally safe, functional, and more material-efficient solution. These findings highlight the potential to reduce the need for external drainage channels, thereby improving spatial efficiency and lowering construction costs. Furthermore, integrating the drainage system into columns allows for cleaner, more minimalist façade designs without conventional piping interruptions, ultimately enhancing the aesthetic value and architectural competitiveness of the building.

Abstract

This study analyzed the impact of Transit Oriented Development (TOD) on transportation mode shifts in Cawang–Cikoko, East Jakarta, using a quantitative approach with multiple linear regression on data from 103 respondents. The findings indicate that TOD significantly influences mode choice by 45.1%, with the Shift variable being most dominant, followed by Connect and Transit, while Walk showed no significant effect, suggesting that TOD development in the area should prioritize intermodal integration and public transportation quality.

Abstract

Construction sequence mismatches in stairwells often necessitate connecting stair slabs to the primary structure after it has already been erected. One practical on-site solution is the use of chemical anchors on the landing beam (edge beam), which interacts with the existing column. This study compares two behavioral schemes: (i) free-standing, where the stair slab spans between floor slabs without relying on the landing beam–column system; and (ii) bearing, where the slab edge rests on the landing beam anchored to the column. Numerical modeling was conducted using SAP2000, employing shell elements for the stair slab and link elements to represent joint stiffness. Gravity loads were defined according to SNI 1727:2020, while flexural–shear capacity evaluations of the slab followed SNI 2847:2019. The observed outputs included bending moment M11, shear V13, service deflection, link reactions, and local forces on the landing beam and column at the drilling zone. Comparative results show that the free-standing scheme reduces force transfer to the column but increases the demand on the stair slab; conversely, the bearing scheme decreases deflection and slab bending moments but raises anchor reactions and local column forces. In the case study, the design flexural capacity φMn of the slab approached but slightly fell below the demand Mu, while the serviceability deflection limit was satisfied. Therefore, the recommendation is conditional: the free-standing scheme is feasible if φMn ≥ Mu and deflection requirements are met; otherwise, slab strengthening or a shift to the bearing scheme with adequate anchor design is required. These findings provide a practical decision-making basis for projects involving non-monolithic stair connections.

Abstract

Formwork removal is a critical stage in reinforced concrete construction as it is directly related to quality, safety, and efficiency. In practice, this process often relies solely on the concrete age in days, without verification of the actual compressive strength, which may lead to cracking, excessive deflection, or even permanent damage. This study aims to analyze the relationship between the development of concrete compressive strength and the capacity of primary structural elements—columns, beams, and slabs—in carrying construction loads, as a basis for determining the safe timing of formwork removal. The method employed consists of a literature review and conceptual analysis based on SNI 2847:2019, ACI 347.2-17, and compressive strength test data at ages 1–28 days. Axial and flexural capacities of the elements were compared with construction loads in accordance with SNI 1727:2020, along with an evaluation of service deflections. The analysis results indicate that columns can be safely stripped at 1 day, as their axial capacity significantly exceeds the applied loads, whereas slabs and long-span beams are safe to dismantle after 14 days, when concrete achieves at least 70% of f’c. These findings confirm that concrete age alone cannot serve as the sole reference; verification of actual strength is crucial to ensure that formwork removal is carried out safely and efficiently.
