EVALUASI TINGKAT PELAYANAN JALAN (STUDI KASUS SIMPANG TAK BERSINYAL BUGIS KABUPATEN MALANG)

Abstract

ABSTRAK Simpang merupakan pertemuan dua atau lebih jalan yang berpotensi menimbulkan konflik lalu lintas dan kemacetan. Permasalahan ini terjadi di Simpang Bugis, Kabupaten Malang, seiring pertumbuhan penduduk yang mencapai lebih dari 2.734.898 jiwa. Penelitian ini bertujuan mengevaluasi tingkat pelayanan simpang, mengetahui volume maksimum kondisi eksisting, serta menentukan solusi penanganan. Analisis menggunakan Pedoman Kapasitas Jalan Indonesia (PKJI 2023) dengan parameter derajat kejenuhan, tundaan, dan peluang antrian. Volume maksimum terjadi pada lengan Utara hari Sabtu pukul 16.00–17.00 WIB, lengan Timur hari Senin pukul 16.00–17.00 WIB, lengan Selatan hari Senin pukul 07.00–08.00 WIB, dan lengan Barat hari Senin pukul 07.00–08.00 WIB. Volume maksimum tercatat pada lengan Utara 331,9 smp/jam, Timur 994,4 smp/jam, Selatan 492,4 smp/jam, dan Barat 1212,9 smp/jam. Hasil analisis menunjukkan Dj 1,235, tundaan 51,66 det/smp, dan peluang antrian 63–128%, sehingga Simpang Bugis berada pada tingkat pelayanan (LOS) E dengan kondisi buruk.

ABSTRACT An intersection is the meeting point of two or more roads that has the potential to create traffic conflicts and congestion. This problem occurs at Bugis Intersection, Malang Regency, due to the rapid population growth, which has reached more than 2,734,898 people. This study aims to evaluate the intersection's level of service, determine the maximum traffic volume under existing conditions, and identify appropriate improvement measures. The analysis was conducted using the Indonesian Highway Capacity Guidelines (PKJI 2023) based on the parameters of degree of saturation, delay, and queue probability. The maximum traffic volumes occurred on the North approach on Saturday from 16:00 to 17:00 WIB, the East approach on Monday from 16:00 to 17:00 WIB, the South approach on Monday from 07:00 to 08:00 WIB, and the West approach on Monday from 07:00 to 08:00 WIB. The recorded maximum traffic volumes were 331.9 pcu/h on the North approach, 994.4 pcu/h on the East approach, 492.4 pcu/h on the South approach, and 1,212.9 pcu/h on the West approach. The analysis results showed a degree of saturation of 1.235, an average delay of 51.66 s/pcu, and a queue probability of 63–128%, indicating that Bugis Intersection operates at Level of Service (LOS) E, representing poor operating conditions.
