PENINGKATAN JALAN MENGGUNAKAN PERKERASAN KAKU (RIGID BETON) PADA RUAS JALAN MAHKOTA IRIGASI UJUNG, KOTA TIMIKA-PAPUA

Introduction

Peningkatan jalan menggunakan perkerasan kaku (rigid beton) pada ruas jalan mahkota irigasi ujung, kota timika-papua. Meningkatkan jalan di Timika, Papua, dengan perkerasan kaku (rigid beton). Perencanaan menggunakan metode AASHTO untuk ketebalan pelat dan beban lalu lintas.

Abstract

Ruas Jalan Mahkota irigasi ujung merupakan bagian dari sistem transportasi sebagai pelayanan sarana infrastruktur bagi dampak pertumbuhan jumlah penduduk. Guna memenuhi kebutuhan tersebut perencanaan perkerasan baru diperlukan untuk melayani kebutuhan lalu lintas di masa yang akan datang. Perkerasan kaku adalah suatu susunan konstruksi perkerasan dimana sebagai lapisan atas dipergunakan pelat beton, yang terletak di atas pondasi atau langsung diatas tanah dasar (Bina Marga, 2003). Konsep dari perencanaan perkerasan kaku (beton semen)  direncanakan terhadap konfigurasi beban sumbu yang mengakibatkan tegangan terbesar pada pelat. Konsep Perencanaan perkerasan Metode AASHTO yaitu tebal pelat rencana akan bertambah sesuai pertambahan lalu lintas ekivalen selama umur rencana dan sebaliknya tebal pelat akan berkurang dengan pengurangan volume lalu lintas ekivalen.akan tetapi dalam menentukan LHR kendaraan hanya menghitung beban sumbu truk saja. Perencanaan Tebal Pelat beton perkerasan jalan dengan menggunakan metode AASHTO 32 cm, sebesar 1-2 cm, Hal ini akibat perbedaan konsep dasar dari Satu metode.

Review

The submitted paper, "Peningkatan Jalan Menggunakan Perkerasan Kaku (Rigid Beton) Pada Ruas Jalan Mahkota Irigasi Ujung, Kota Timika-Papua," tackles a pertinent and practical issue of infrastructure development in response to population growth. The focus on enhancing a specific local road, Mahkota Irigasi Ujung, using rigid concrete pavement in Timika-Papua, demonstrates a direct application of civil engineering principles to address regional needs. The abstract clearly outlines the objective of designing a new pavement to accommodate future traffic demands, utilizing the AASHTO method for pavement thickness, which is a recognized standard in the field. However, the abstract presents several critical areas that demand further clarification and robust methodological justification. A significant concern arises from the statement "dalam menentukan LHR kendaraan hanya menghitung beban sumbu truk saja." While truck axle loads are indeed primary drivers for rigid pavement design, the exclusive focus on them without explicit reasoning could lead to an incomplete traffic load assessment and potentially impact the accuracy of the design and projected lifespan. Moreover, the concluding sentence, "Perencanaan Tebal Pelat beton perkerasan jalan dengan menggunakan metode AASHTO 32 cm, sebesar 1-2 cm, Hal ini akibat perbedaan konsep dasar dari Satu metode," is highly ambiguous. It suggests a discrepancy in the calculated pavement thickness (implying a 32 cm design with a 1-2 cm difference) attributed to a "perbedaan konsep dasar dari Satu metode." This needs precise elaboration: what are these differing conceptual bases, and how do they manifest in such a numerical variance? In conclusion, the paper addresses a relevant local engineering problem with a commendable practical approach. Nevertheless, for this work to meet scholarly publication standards, major revisions are imperative. The authors must provide a comprehensive justification for the specific traffic load considerations and thoroughly explain the "perbedaan konsep dasar" that leads to the stated discrepancy in pavement thickness. A more detailed and coherent presentation of the problem, the specific application of the AASHTO methodology, and a clearer articulation of the design results, including how any observed discrepancies were resolved or accounted for, are essential to enhance the paper's rigor and contribution. Without these substantial clarifications, the current abstract, and consequently the implied research, lacks the necessary depth and clarity expected for a peer-reviewed journal.
