Abstract

Based on National Railway Master Plan (RIPNAS)in 2030, there is an increase in train passenger travel on Java Island by 858.5 million people/year. The capacity of the railway track is inadequate because it still uses a single track on the Mojokerto - Boharan line so that there is a plan for a double track railway. On Java Island, there are 2 railway routes, namely the northern route (pantura) and the southern route. For the northern route or the North Coast route connecting Jakarta and Surabaya, it is already a double track. While for the southern route in the form of a double track, it is still realized on the Jombang - Mojokerto track. Then, on the Mojokerto - Boharan track, the existing railway line is still a single track or single track. The main focus of this study is the planning of a double track railway at the placement of Mojokerto - Boharan Station (KM 53 + 400 - KM 51 + 700). The structure of the double track railway in the Mojokerto - Boharan section that was reviewed was the planning of a double track railway that was given a geotextile layer against the aspect of the planned railway load. The guidelines used in this design are the Regulation of the Service No. 10 of 1986 from PT. KAI. As a result of this study is a review of the safety factor due to dead load damage to the railway structure, the safety factor of slope and lateral swelling against the reinforcement of the geotextile layer meets the requirements.

Abstract

The Situbondo City - Bajulmati Road Section (Banyuwangi Regency) is one of the national roads connecting Situbondo City and Banyuwangi Regency. This road section is one of the national roads with a fairly high accident rate given the condition of the road on the hills. The frequent occurrence of traffic accidents on this road section is caused by the topography of the road which has hilly characteristics. The hilly topography causes the Situbondo City - Bajulmati (Banyuwangi Regency) STA 0+000 - STA 5+000 road section to have a road with long inclines and descents that have a risk of brake failure and loss of control of the vehicle on steep and cornering roads. The horizontal alignment evaluation uses the Bina Marga Method in the form of the 2021 Road Geometric Design Guidelines. This guideline is the latest guideline issued by Bina Marga in 2021 to replace the 1997 Road Geometric Planning Procedure. Horizontal alignment evaluation is carried out by analyzing the degree of bend, bend radius, length of the transition curve and type of horizontal bend. From the results of the evaluation of the horizontal alignment of the highway on the Situbondo City - Bajulmati Road section (Banyuwangi Regency), it is known that the calculation of the horizontal alignment using the Bina Marga method results in a horizontal alignment evaluation of 13 Spiral-Circle-Spiral type bends.

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

Indonesia, as a country with vast territory and a continuously growing population, faces significant challenges in providing adequate transportation infrastructure. Railways have become one of the most preferred modes of transportation among the public, making the improvement of railway line capacity an urgent necessity particularly along the southern Surabaya–Banyuwangi corridor, which has not yet been fully developed into a double track. One such segment is the line from Arjasa Station to Kalisat Station. On this segment, train frequency remains limited due to the single-track configuration, which impacts various sectors. This study focuses on the Arjasa–Kalisat segment, which includes three stations: Arjasa, Kotok, and Kalisat. The objective of this research is to evaluate the line’s transport capacity and geometric track design as part of the efforts to develop a double-track railway. The analysis shows that the transport capacity of the segment reaches 3,983,126 tons per year and is classified as a Class IV railway. This segment uses R.54 type rails with a gauge of 1,067 mm, comprising 13 horizontal curves with radii ranging from 270 to 850 meters, and 23 vertical curves with a radius of 6,000 meters. These findings provide a crucial foundation for planning future railway infrastructure improvements to support smooth mobility and regional economic growth.

Abstract

Traffic safety at night is strongly influenced by the quality of road lighting, particularly on newly constructed roads with complex geometric characteristics. This study aims to analyze the effectiveness of solar-powered Public Street Lighting (PJU) in improving transportation safety on the Southern Cross Road (JLS) Lot 3 Blitar and to compare it with JLS Lot 7, which is not yet equipped with lighting facilities. The research adopts a qualitative approach through nighttime field observations, visual documentation, road geometry analysis, literature review, and data triangulation with Road Safety Audit (RSA) recommendations. The solar-powered lighting system evaluated is the Integrated Solar System Light (ISSL) 80 W, installed at critical locations such as Spiral–Circle–Spiral (S–C–S) curves, an 80 m bridge, and segments prone to dark spots. The results indicate that increasing the number of lighting units from 49 to 102 significantly enhances visibility, improves drivers’ perception of road geometry, and reduces the risk of single-vehicle and run-off-road accidents. Adequate lighting also contributes to improved psychological comfort for road users. Furthermore, the application of solar energy through the ISSL 80 W system supports energy efficiency and sustainable road infrastructure development
