Abstract

Kota Surabaya termasuk wilayah yang memiliki tingkat kerawanan terhadap bencana banjir, salah satunya berada di Kecamatan Pakal. Upaya penanganan banjir melalui pembangunan infrastruktur drainase juga sejalan dengan tujuan pembangunan berkelanjutan, khususnya SDGs ke-9 yang menitik beratkan pada pembangunan infrastruktur yang tangguh serta inovasi teknologi. Tercatat bahwa di kawasan ini terdapat kurang lebih tujuh titik genangan yang sempat terjadi dalam beberapa waktu terakhir. Penelitian ini bertujuan untuk mengevaluasi kinerja dimensi box culvert dalam upaya pengendalian banjir di Kecamatan Pakal, Surabaya. Metode penelitian dilakukan melalui analisis data curah hujan harian periode 2009–2024 menggunakan Distribusi Log Pearson Tipe III untuk memperoleh curah hujan rencana. Selanjutnya, debit banjir rencana dihitung dengan metode rasional. Kapasitas hidrolis box berukuran 7,00 m × 3,50 m dan kemiringan rencana sebesar 0,0005%, dianalisis menggunakan persamaan Manning guna mengetahui kemampuan saluran dalam mengalirkan debit banjir. Hasil perhitungan menunjukkan bahwa kapasitas box culvert yang direncanakan mampu menampung debit sebesar 61,197 m³/det, yang nilainya lebih besar dibandingkan debit banjir periode ulang 10 tahun sebesar 14,03 m³/det. Dengan demikian, dimensi box culvert tersebut dinilai efektif dalam menurunkan potensi genangan di wilayah Kecamatan Pakal.

Abstract

Soenandar Priyo Sudarmo Road, located in Sidoarjo Regency, East Java, is surrounded by various industrial facilities and storage warehouses, leading to significant stress on the pavement due to heavy vehicle traffic. This condition increases the risk of pavement deterioration. Therefore, this study aims to evaluate the impact of overloaded vehicles on the remaining service life of the pavement along Soenandar Priyo Sudarmo Road. The study utilizes both secondary data—such as Average Daily Traffic (ADT) and vehicle loads—and primary data obtained through field traffic surveys. The AASHTO 1993 method is employed to analyze the effect of vehicular loads on pavement life. Two scenarios are assessed: first, assuming all vehicles comply with standard axle loads; and second, analyzing the condition with overloaded freight vehicles based on actual overload data. Calculations include ESAL, W18, truck factor, and remaining pavement life. The analysis results indicate that the cumulative standard load (ΣW18) ranges from 372,983.25 to 16,839,371.72, while the overloaded condition ranges from 731,161.54 to 31,982,312.35. The remaining life percentage under overloaded traffic is reduced by 31%, resulting in a decreased service life of 3.1 years. Consequently, the pavement is projected to reach the end of its design life by November 2028.

Abstract

Motorcycles dominate traffic composition in East Surabaya, making the determination of Passenger Car Equivalent (PCE) values for motorcycles a crucial aspect of road performance assessment. This research evaluates motorcycle PCE value on six road sections on Raya Prapen Street, Jemursari Street, Jemur Andayani Street, Panjang Jiwo Street, Kali Rungkut Street, and Rungkut Industri Street, each observed in two directions (12 segments in total), with samples collected during peak hours on Monday (06:00–10:00) and Friday (15:00–19:00). The Time Headway method is used to calculate the PCE value, and followed by statistical procedures, including t-tests and the calculation of the coefficient of determination, were performed using SPSS software. Findings show a strong correlation between PCE values and the characteristics of each road section. The adjusted motorcycle PCE values range from 0.12 to 0.20 across all sections, with site-wise pairs for direction 1/direction 2 as follows: Raya Prapen 0.20/0.16, Jemursari 0.18/0.19, Jemur Andayani 0.14/0.12, Panjang Jiwo 0.20/0.19, Kali Rungkut 0.15/0.16, and Rungkut Industri 0.15/0.14. The result coefficient of determination of R2 = 0.817 indicates a strong association between Time Headway and PCE Values. This research is limited by the assumption of a uniform motorcycle dimension factor across all sections.
