Analisis Perbandingan Biaya Siklus Hidup Perkerasan Lentur dan Perkerasan Kaku Jalan Bencorejo-Angkrukketip Kabupaten Purworejo

Introduction

Analisis perbandingan biaya siklus hidup perkerasan lentur dan perkerasan kaku jalan bencorejo-angkrukketip kabupaten purworejo. Analisis biaya siklus hidup perkerasan lentur & kaku Jalan Bencorejo-Angkrukketip Purworejo. Temukan perkerasan kaku lebih efisien 1,47 kali, menghemat anggaran proyek jalan.

Abstract

Pembangunan infrastruktur jalan memerlukan biaya awal yang besar, selain itu biaya tidak hanya diukur dari pembiayaan awal saja, tetapi juga biaya perawatan dan rehabilitasi jalan di masa yang akan datang. Penelitian ini bertujuan untuk menganalisis tebal lapis perkerasan lentur dan perkerasan kaku, perbandingan total biaya siklus hidup perkerasan lentur dan perkerasan kaku, jenis perkerasan yang lebih efisien untuk ruas Jalan Bencorejo - Angrukketip, Kabupaten Purworejo. Penelitian ini menggunakan metode kuantitatif. Penentuan tebal perkerasan lentur dan perkerasan kaku menggunakan metode Manual Desain Perkerasan Jalan 2017. Data primer yang digunakan dalam penelitian ini adalah data LHR dan data CBR tanah, sedangkan data sekunder meliputi harga upah, alat, dan bahan Kabupaten Purworejo, data inflasi, dan data suku bunga.Hasil dari penelitian untuk tebal perkerasan lentur adalah AC-WC 40 mm, AC-BC 60 mm, dan lapis pondasi agregat kelas A 400 mm, sedangkan untuk perkerasan kaku adalah beton (fs) 45 MPa dengan tebal 175 mm dan lapis pondasi kelas A dengan tebal 125 mm, jenis perkerasan kaku beton bersambung tanpa tulangan (BBTT) dengan dowel. Diameter dowel yang digunakan 28 mm, panjang 450 mm, jarak 300 mm, dan diameter tie bar 16 mm, panjang 700 mm, jarak 750 mm. Nilai discounted life cycle cost untuk perkerasan lentur Rp 6.417.595.391,14 sedangkan nilai discounted life cycle cost perkerasan kaku Rp 4.378.123.644,16. Dapat disimpulkan bahwa perkerasan lentur membutuhkan biaya 1,47 kali lebih besar dibandingkan perkerasan kaku. Analisis biaya menunjukkan bahwa perkerasan kaku merupakan pilihan yang lebih efisien untuk ruas jalan Bencorejo – Angkrukketip Kabupaten Purworejo.

Review

This paper, "Analisis Perbandingan Biaya Siklus Hidup Perkerasan Lentur dan Perkerasan Kaku Jalan Bencorejo-Angkrukketip Kabupaten Purworejo," addresses a critical issue in civil engineering and infrastructure development: the long-term cost-effectiveness of road construction. Recognizing that initial construction costs are only one component of a road's total economic impact, the study sets out to conduct a comprehensive life cycle cost (LCC) analysis. The primary objectives are to determine the optimal thickness design for both flexible and rigid pavements for the specific Bencorejo-Angkrukketip road segment in Purworejo Regency, compare their total LCCs, and ultimately identify the more efficient pavement type for this particular stretch of road. This localized focus provides valuable practical insights for regional infrastructure planning. The research employs a quantitative methodology, utilizing the Manual Desain Perkerasan Jalan 2017 for pavement thickness design, which lends strong methodological rigor to the engineering aspects. Data collection was comprehensive, incorporating primary sources such as daily traffic (LHR) and California Bearing Ratio (CBR) soil data, alongside secondary data including local costs for labor, equipment, and materials, as well as inflation and interest rates pertinent to Purworejo Regency. The findings are highly specific and impactful: for flexible pavement, the optimal design consisted of AC-WC 40 mm, AC-BC 60 mm, and a 400 mm Class A aggregate base. In contrast, the rigid pavement design specified 175 mm thick concrete (fs 45 MPa) with a 125 mm Class A base, identified as dowel-jointed plain concrete pavement (BBTT), with detailed specifications for dowel and tie bar dimensions. Crucially, the discounted LCC analysis revealed a significant difference: flexible pavement cost Rp 6,417,595,391.14, whereas rigid pavement cost Rp 4,378,123,644.16. This translates to flexible pavement being approximately 1.47 times more expensive over its life cycle, leading to the clear conclusion that rigid pavement is the more efficient choice for the target road. This study provides a valuable contribution to the field by offering a concrete, data-driven comparison of pavement types tailored to a specific local context. Its strength lies in its meticulous application of recognized design standards (MDPJ 2017) and the inclusion of comprehensive economic factors (inflation, interest rates, and discounted LCC) which are often overlooked in initial cost assessments. The clear recommendation for rigid pavement on the Bencorejo-Angkrukketip road segment offers direct, actionable insights for local authorities and planners in Purworejo. Furthermore, the methodology could serve as a replicable framework for similar LCC analyses in other regions of Indonesia or developing countries facing comparable infrastructure challenges, encouraging a more sustainable and economically sound approach to road development that considers long-term value beyond initial construction expenses.
