Abstract

Jalan Lingkar Tuban is a national strategic route on the north coast of Java that serves as an alternative to overcome various obstacles. It is expected that this road can encourage the overall growth of the city, improve the convenience of vehicle accessibility, and encourage economic growth without causing congestion. To achieve this, good pavement is essential. Given the high traffic volume and overloading that will be travelled on the Tuban Ring Road, rigid pavement planning is highly recommended. The method used in this research is the AASHTO 1993 method, as it has been widely adopted by many countries abroad. The result of this research is 390 mm thick rigid pavement, 100 mm foundation layer (LMC), and 150 mm drainage layer.  The cost budget plan obtained results worth Rp 128,804,000,000 (One Hundred TwentyEight Billion Eight Hundred Four Million Rupiah).

Abstract

The increasing intensity of economic activity and traffic movement in the Babat Highway area, Lamongan Regency, has given rise to various transportation problems, particularly related to the performance of pedestrian facilities and road capacity. This study aims to analyze the level of service (LOS) on existing pedestrian paths and road sections and to develop effective traffic engineering management strategies to accommodate community mobility needs. The methodology used includes a primary survey in the form of traffic counting and spot speed studies for pedestrians and motorized vehicles. The data obtained were then analyzed using the 2014 Indonesian Road Capacity Guidelines (PKJI). The results show that the pedestrian path has not met minimum service standards, characterized by low LOS values ​​and high conflicts between pedestrians and vehicles. In addition, the road section shows a degree of saturation (DS) value that is close to the capacity threshold, indicating the need for traffic engineering interventions. The resulting recommendations include redesigning sidewalks by taking into account user dimensions and needs, rearranging parking spaces, controlling side obstacles, and improving road geometry. The implementation of this strategy is expected to improve safety, movement efficiency, and comfort for road users in a sustainable manner.

Abstract

Dhoho Airport in Kediri serves as a vital air transportation infrastructure supporting regional mobility. However, no intermodal transport service currently connects Tamanan Terminal to the airport. This study aims to design an airport shuttle bus system that provides an effective and efficient linkage. Data were collected through interviews and questionnaires using the stated preference method, focusing on service effectiveness attributes. The planning analysis refers to the Technical Guidelines of the Directorate General of Land Transportation No. SK.687/AJ.206/DRJD/2002. The proposed mode of transport is the E-Inobus electric bus with a capacity of 24 passengers. The analysis results indicate 15 designated stops along the route, with a total circulation time of 73 minutes. The load factor is estimated at 25%, with an average headway of 13 minutes. A total of bus 20 unitsare required, operating at a frequency of 2 vehicles per hour. The average passenger waiting time is 13 minutes, and the operating speed is set at 30 km/h. This planning is expected to provide an integrated intermodal transport service that enhances accessibility and travel efficiency to and from Dhoho Airport.

Abstract

Kabupaten Lamongan mengalami peningkatan aktivitas ekonomi dan mobilitas, terutama pada koridor Lamongan selatan menuju pusat kabupaten, sedangkan moda transportasi umum belum menjangkau Kecamatan Mantup sehingga masyarakat bergantung pada sepeda motor, yang memicu perjalanan mahal, risiko kecelakaan, dan kesenjangan akses. Penelitian ini bertujuan merencanakan rute baru angkutan kota Mantup–Lamongan Kota yang layak secara operasional dengan mengkaji karakteristik calon pengguna, kebutuhan armada, headway, load factor, serta jumlah dan lokasi titik henti. Data primer diperoleh melalui survei kuesioner dengan sampel menggunakan rumus Slovin, sedangkan data sekunder berupa jumlah penumpang angkutan kota rute Babat–Lamongan 2020–2024 digunakan sebagai pembanding. Hasil analisis menunjukkan sekitar 60 persen penumpang menuju Lamongan berasal dari kawasan Mantup, sehingga diusulkan rute Mantup–Lamongan–Mantup sepanjang 21 km, tujuh armada, headway 31,5 menit, dan lima titik henti. Proyeksi lima tahun menunjukkan kenaikan load factor dari 72,69 persen menjadi 77,49 persen sehingga rute dinilai potensial meningkatkan aksesibilitas dan mengurangi ketergantungan kendaraan pribadi.

Abstract

Trans Jatim is a provincial bus-based public transport system initiated by the East Java Government to strengthen regional connectivity and alleviate traffic congestion, particularly within the Gerbangkertosusila metropolitan area. One of the newly introduced corridors, Corridor V, operates along the Surabaya–Bangkalan route via the Suramadu Bridge. This study aims to assess the operational performance of this corridor by focusing on three key indicators: load factor, travel time, and headway. A field survey with an observational approach was conducted to collect primary data directly from actual operations. The findings indicate that the average load factor reached only 42%, which falls short of the required minimum standard of 70%. In contrast, the average travel time of 118 minutes and headway of 20 minutes both meet the acceptable thresholds outlined in official technical guidelines. These results reveal that among the evaluated indicators, only the load factor fails to comply with the service standards. The insights from this research are expected to serve as a reference for enhancing the efficiency and service quality of the Trans Jatim Bus Corridor V in a more sustainable manner.
