Abstract

Seiring dengan mobilitas penduduk yang cukup signifikan maka perlu adanya analisa tingkat pelayanan yang nantinya akan memenuhi syarat dalam penggunaan jasa angkutan umum.Tujuan penelitian ini adalah untuk menganalisa kinerja atau tingkat pelayanan angkutan umum penumpang dari segi kenyamanan, keamanan dan ketepatan waktu serta menganalisa penentuan tarif angkutan umum penumpang yang melayani trayek Sorong - Klamono dengan menggunakan metode Ability To Pay (ATP) dan Willingness To Pay (WTP). Metode yang di gunakan dalam penelitian ini menggunakan pendekatan kuntitatif yang didalamnya berisikan survey dan kuisioner atau angket sebagai instrumen penelitian serta dokumentasi. Data yang dihasilkan kemudian akan diolah dan dianalisis sesuai tujuan penelitian. Adapun hasil dari penelitian ini menyimpulkan bahwa tingkat pelayanan pada angkutan umum trayek Sorong – Klamono berdasarkan indikator penilaian prestasi kerja dari parameter kenyamanan, keamanan dan ketepatan waktu dikatakan masih dalam kondisi baik serta keinginan pengguna untuk membayar jasa angkutan lebih besar daripada kemampuan membayarnya dikarenakan pengguna mempunyai penghasilan yang relatif rendah tetapi utilitas atau manfaat yang dirasakan pengguna terhadap jasa tersebut sangat tinggi

Abstract

This study aims to evaluate the feasibility of incorporating Type C excavation waste and beach sand as alternative fine aggregate and filler materials in Hot Rolled Sheet–Wearing Course (HRS-WC) mixtures. A laboratory-based experimental approach was conducted to assess the mechanical performance and durability characteristics of the proposed mixtures. The results reveal that the mixture utilizing beach sand achieved the most balanced performance at an optimum bitumen content of 7.35%, with a stability value of 1755.78 kg and an air void (VIM) of 4.15%, fully complying with the 2018 Bina Marga specification. Moreover, the combination of excavation waste and beach sand fillers significantly improved moisture resistance, yielding the highest Index Retained Strength (IRS) of 127.39% and the lowest Cantabro loss of 0.59%. These findings indicate that the synergistic use of excavation waste and beach sand not only enhances mixture performance but also reduces the demand for natural aggregates and mitigates construction waste disposal. In practical terms, this approach supports a more sustainable, resilient pavement design for coastal infrastructure, where material scarcity and chloride exposure are major challenges. Overall, the study highlights the potential of locally available materials such as excavation waste and beach sand to produce HRS-WC mixtures that meet technical performance standards while promoting sustainable, cost-effective, and resource-efficient road construction in coastal regions.
