Abstract

A pavement management system needs to be implemented as a form of road management to ensure that roads function properly. The Markov Chain model describes future pavement conditions to produce optimal highway maintenance. The research was carried out on Suprapto Street, Ahmad Yani Street, and Yos Sudarso Street in Indramayu Regency. Based on road conditions in 2024 by PCI and SDI assessment results, predictions are made by multiplying the initial condition vector by the transition probability matrix. Once the condition of the road is known, the proposed type of maintenance can be determined based on Ministerial Regulation of Public Work No. 13/PRT/M/2011, along with the costs required based on the maintenance cost history. The Markov Chain predictions show that road conditions will deteriorate and there will be an increase in severe damage over the years if no treatment is carried out. Maintenance action patterns vary; sections that experience a high level of damage will receive more serious treatment, and in the following year maintenance will decrease and then increase again according to the level of damage. The pattern of maintenance costs also follows the handling actions taken. Costs in the initial year were the highest, while most costs were spent on Suprapto Street.

Abstract

Trotoar merupakan fasilitas penting dalam mendukung mobilitas pejalan kaki di kawasan perkotaan. Namun, pada kawasan dengan fungsi campuran, pemanfaatannya sering terganggu oleh aktivitas lain dan kondisi fisik yang belum memenuhi standar. Penelitian ini bertujuan untuk menganalisis tingkat kenyamanan pejalan kaki serta mengevaluasi kesesuaian trotoar di Jalan Kusuma Kebumen berdasarkan Permen PU No. 03 Tahun 2014. Metode yang digunakan adalah deskriptif kuantitatif melalui observasi lapangan, pengukuran dimensi trotoar, dan penyebaran kuesioner. Analisis dilakukan menggunakan pendekatan persentase terhadap aspek kenyamanan fisik, psikologis, fungsional, dan visual. Hasil penelitian menunjukkan tingkat kenyamanan pejalan kaki berada pada kategori cukup nyaman sebesar 56,43%, sedangkan pemenuhan standar trotoar baru mencapai sekitar 50%. Permasalahan utama meliputi lebar trotoar yang belum sesuai standar, adanya hambatan berupa pedagang kaki lima dan parkir liar, serta belum tersedianya fasilitas aksesibilitas seperti ramp pada elevasi trotoar dan guiding block pada jalur trotoar. Kondisi ini menunjukkan trotoar belum berfungsi optimal sebagai ruang pejalan kaki yang aman, nyaman, dan inklusif.

Abstract

Kondisi perkerasan jalan merupakan faktor penting yang mempengaruhi kenyamanan, keselamatan, dan tingkat pelayanan lalu lintas. Penurunan kondisi jalan yang tidak ditangani secara tepat dapat menyebabkan peningkatan biaya pemeliharaan di masa mendatang. Penelitian ini bertujuan untuk mengevaluasi kondisi perkerasan jalan serta menentukan jenis pemeliharaan yang sesuai menggunakan metode Surface Distress Index (SDI). Objek penelitian adalah ruas Jalan Boncorejo di Kabupaten Purworejo dengan panjang total 1.000 meter. Metode penelitian yang digunakan adalah survei visual lapangan dengan membagi ruas jalan menjadi sepuluh segmen pengamatan masing-masing sepanjang 100 meter. Hasil penelitian menunjukkan bahwa kondisi jalan didominasi oleh kategori sedang sebesar 80,00%, sedangkan kategori rusak ringan sebesar 20,00%. Berdasarkan nilai SDI dan mengacu pada ketentuan Permen PU No. 13/PRT/M/2011, jenis penanganan yang direkomendasikan adalah pemeliharaan berkala pada segmen dengan kondisi sedang dan rehabilitasi pada segmen dengan kondisi rusak ringan. Hasil penelitian ini menunjukkan bahwa metode SDI efektif digunakan untuk menggambarkan kondisi perkerasan jalan dan mendukung penentuan program pemeliharaan yang tepat. Pendekatan ini diharapkan dapat membantu pengelola jalan dalam menyusun strategi pemeliharaan yang lebih efisien dan berkelanjutan.

Abstract

In Wonosobo Regency, Central Java, mountainous terrain and high economic activity have contributed to a significant increase in motor vehicles. This growth has placed pressure on road infrastructure, particularly at strategic intersections such as the Pasar Kertek Roundabout. This unsignalized four-leg intersection connects traffic from several directions and carries thousands of motorized and non-motorized vehicles each day. The combination of local traffic, regional freight transport, and side friction from traditional market activities causes vehicle conflicts, long queues, and congestion. This study analyzes the intersection’s performance in terms of capacity, degree of saturation, delay, and queue probability, and determines its level of service (LOS). A quantitative approach was used, following the 1997 Indonesian Highway Capacity Manual (MKJI). Primary data on traffic volume, side friction, and road geometry were collected alongside secondary data. The highest peak-hour traffic volume occurred on Monday, 4 May 2026, from 07:00 to 08:00 Western Indonesian Time, reaching 11,284 vehicles/hour, equivalent to 6,568.5 passenger car units/hour (pcu/hour). Based on MKJI 1997, the capacity of the roundabout’s weaving sections ranged from 1,459.26 pcu/hour (section AB) to 2,243.92 pcu/hour (section DA). All sections were oversaturated, with degrees of saturation exceeding the specified threshold of 0.85: 1.17 for AB, 1.70 for BC, 1.69 for CD, and 1.26 for DA. These conditions resulted in substantial traffic delays and high queue probabilities throughout the roundabout. All weaving sections were classified as LOS F, indicating severely congested flow. Traffic engineering and area management measures are therefore needed, including restricting access to Sukardi Road to market operations, enforcing rules against unauthorized parking and roadside motorcycle taxi stands, relocating street vendors, and reducing side friction caused by public transport vehicles stopping on the road shoulder.
