Abstract

Traffic conflicts are an indicator that can be used to identify potential accidents before they occur. Jalan Laswi in Bandung City is an urban arterial road with high traffic activity, where various violations, such as U-turns, crossings, and counter-traffic, are still found, potentially increasing traffic conflicts. This study aims to identify the types of conflicts, determine the level of seriousness of the conflicts based on violations using the Traffic Conflict Technique (TCT) method, and map the distribution of conflict levels on Jalan Laswi in Bandung City. Data collection was conducted through a survey of traffic volume, traffic conflicts, vehicle speeds, and distance between vehicles over three days of observation. Analysis was conducted using Time to Accident (TA) and Traffic Conflict (TC) parameters. The results show that conflicts are dominated by U-turns, crossings, and counter-traffic, with the highest concentration in Segment 3. The highest TA value of 0.52 seconds is categorized as a non-serious conflict, while the lowest value of 0.10 seconds is categorized as a serious conflict. The highest conflict rate reached 100,504 conflicts per 1,000 vehicles in Segment 3 northbound, while the lowest conflict rate was 0.131 conflicts per 1,000 vehicles in Segment 1 northbound. The results of the study indicate that the TCT method is effective in identifying priority locations for handling and supporting preventive traffic safety efforts.

Abstract

Pembangunan basement pada kondisi tanah lunak memerlukan sistem penahan tanah yang mampu menjaga stabilitas galian dan mengendalikan deformasi tanah. Penelitian ini bertujuan untuk menganalisis pengaruh variasi diameter secant pile terhadap stabilitas dan deformasi galian basement serta menentukan diameter yang paling efisien. Analisis dilakukan pada galian sedalam 7,45 m di sebuah gedung komersial di Jakarta Selatan menggunakan metode elemen hingga (Finite Element Method/FEM) dengan bantuan perangkat lunak Plaxis 2D. Variasi diameter secant pile yang dianalisis yaitu 0,6 m, 0,8 m, dan 1,0 m pada kondisi pembebanan statik dan gempa. Parameter evaluasi meliputi faktor keamanan dan deformasi maksimum berdasarkan SNI 8460:2017. Hasil analisis menunjukkan bahwa galian tanpa perkuatan tidak memenuhi persyaratan faktor keamanan, sedangkan seluruh variasi secant pile mampu meningkatkan stabilitas galian hingga memenuhi persyaratan yang ditetapkan. Namun, diameter 0,6 m menghasilkan deformasi maksimum sebesar 4,22 cm yang melebihi batas izin sebesar 3,725 cm, sedangkan diameter 0,8 m dan 1,0 m masing-masing menghasilkan deformasi maksimum sebesar 3,57 cm dan 3,13 cm sehingga memenuhi batas deformasi yang diizinkan. Berdasarkan hasil tersebut, diameter secant pile 0,8 m direkomendasikan sebagai alternatif yang paling efisien karena memenuhi persyaratan faktor keamanan dan batas deformasi sesuai SNI 8460:2017.
