Abstract

Green mobility is one of the main solutions to reduce the environmental impact of transportation, as well as to support sustainable urban development. This study aims to identify strategies for implementing green mobility in urban areas using the SWOT (Strengths, Weaknesses, Opportunities, Threats) and STP (Segmentation, Targeting, Positioning) analysis approaches. This study uses a qualitative method based on literature studies that examine various sources related to policies, infrastructure, and green mobility practices in various cities. The results of the SWOT analysis show that the main strength of green mobility implementation lies in green mobility being an environmentally friendly transportation with low operational costs and can reduce congestion, although there are weaknesses in terms of inadequate infrastructure and resistance to behavioral change. Opportunities that can be utilized include support from government policies and global trends towards smart cities and increased investment in the environmentally friendly transportation sector, while threats faced by resistance from the conventional vehicle industry include high dependence on private motor vehicles. In the STP analysis, market segmentation is carried out based on geographic, demographic, and psychographic characteristics, targeting urban workers who are more open to environmentally friendly transportation solutions. Green mobility is positioned as an efficient, cost-effective, and environmentally friendly transportation option. Based on the analysis results, it is suggested that transportation policies that support green mobility focus on developing better infrastructure, educational campaigns, and policy support from the government. Thus, the implementation strategy obtained is green mobility education to the community, development of supporting infrastructure, provision of incentives and subsidies, and government policies that support the implementation of green mobility.

Abstract

Bekasi City as one of the main buffers of DKI Jakarta is experiencing rapid population growth, accompanied by an increasing need for public transportation. Urban Transportation (Angkot) K19A is one of the vital modes of transportation for the community, especially for trips to work, school, and shopping centers. However, the increasing number of users means that the K19A fleet is often unable to meet the needs of the community, which is characterized by passenger density during peak hours and long waiting times. This condition has the potential to reduce the quality of service and encourage a shift to private vehicles, which can worsen congestion and air pollution. This study aims to analyze the need for additional K19A fleets based on passenger demand data, travel patterns, and route efficiency. By using a data-based approach, the results of the study are expected to be the basis for policy makers in formulating strategies to improve more effective and sustainable public transportation services in Bekasi City

Abstract

At intersections, traffic performance indicators consist of saturation degree, queue length, and delay. There are several methods commonly used to calculate performance indicators at intersections, including the PKJI method (2023) and the RJ method. Salter (1981). Each method produces different performance values. Between the PKJI 2023 method and the RJ method, it is not yet known which method is most representative of field conditions, therefore it is necessary to identify which method produces performance that is most in accordance with real conditions in the field. There are several differences and similarities between the analysis of signalized intersections with the PKJI 2023 and RJ methods. Salter, namely the emp value between the PKJI 2023 method and the RJ Salter method, it can be seen that the PKJI 2023 method divides the emp into 2 (two), namely protected and opposed emp, while RJ Salter does not divide it. The magnitude of the emp value is also different for each type of vehicle, this is likely due to the characteristics of vehicle behavior and the geometry of the intersection. In addition, the saturation current formula between the two methods is different, but in the PKJI 2023 and RJ methods. Salter has a So variable (basic saturation current) in the formula. Calculation of cycle time analysis, green time, and approach capacity of the 2nd intersection method with the same approach. Calculation of traffic behavior in this case the queue length and traffic delay from the 2 methods are different. The results of the Mann-Whitney test between the median performance parameters from the survey results and PKJI 2023 show that there is a difference. While the test results between PKJI 2023 and RJ. Salter there is no difference.

Abstract

This study aims to analyze the effect of load variation on braking efficiency and disc temperature in Yamaha Aerox automatic motorcycles equipped with an Anti-lock Braking System (ABS) using the roadtest method. The experimental research method was applied, with independent variables including load variations (65 kg, 85 kg, 130 kg, and 150 kg) and two ABS conditions (active and inactive). The dependent variables observed were braking distance, deceleration, braking efficiency, and disc temperature. The research findings indicate that at low speeds (40 km/h), the ABS system results in a longer braking distance compared to non-ABS conditions. However, at high speeds (50 km/h), ABS proves to be more effective in optimizing braking performance and preventing wheel lock, especially under heavier loads. The lowest average value in braking efficiency is obtained in the ABS ON 40 km/h treatment with a load of 150 kg, the result is 51%. while the highest average value of efficiency is obtained in the ABS ON 50 km/h treatment with a load of 65 kg, the result is 92%. Additionally, load variation significantly affects the increase in disc temperature, with heavier loads leading to higher disc temperatures after braking. The lowest average for disc temperature was obtained in the ABS ON 40 km/h treatment with a load of 65 kg, the value is 37.16 degrees Celsius. while the highest average value of disc temperature was obtained in the ABS OFF 50 km/h treatment with a load of 150 kg with an average value of 73.1 degrees Celsius. This study provides valuable insights into the effectiveness of ABS in enhancing road safety and highlights the importance of regulatory considerations regarding the implementation of ABS in motorcycles in Indonesia.

Abstract

The development of transportation, especially the use of motorcycles has contributed significantly to increasing community mobility. However, along with the increasing number of vehicles, the risk of traffic accidents has also increased. One of the main factors causing accidents is the failure of the braking system, which most often occurs in two-wheeled vehicles. Automatic motorcycles, which generally still use conventional braking systems, have a higher level of vulnerability to brake failure compared to other types of vehicles. The ease of use of automatic motorcycles makes this vehicle the main choice for people in their daily activities. One of the braking system technologies developed by motorcycle manufacturers in Indonesia is the Combi Brake System (CBS), which aims to improve the safety of motorcycle riders. This study aims to analyze the comparison of braking efficiency between the CBS and Non-CBS systems by considering variations in load and type of road pavement construction. The research method uses an experimental approach with the road brake test method at speeds of 40 km/h and 60 km/h. The test results showed that the highest brake efficiency of 56.76% occurred on asphalt roads with active CBS brakes and a load of 65 kg at a speed of 60 km/h, while the lowest efficiency of 23.28% occurred on concrete roads with inactive CBS brakes and a load of 125 kg at a speed of 40 km/h. . While the brake temperature analysis showed the highest value of 79.34 °C on asphalt roads with CBS brakes off and 125 kg load at 60 km/h speed, while the lowest temperature of 48.36 °C occurred on concrete roads with CBS brakes on and 65 kg load at 40 km/h speed.

Abstract

Balise jalur adalah perangkat elektronik yang ditempatkan di antara dua rel atau di atas bantalan rel pada jalur kereta api untuk berkomunikasi dengan transponder di sarana perkeretaapian, menentukan posisi kereta, dan mengaktifkan fungsi lainnya. Di LRT Jabodebek, digunakan Eurobalise 21 yang harus dipasang dengan presisi sesuai standar untuk beroperasi optimal. Pada pemeriksaan Balise pada LRT Jabodebek terdapat 3 parameter tolak ukur yang diperhatikan yaitu pengukuran ketinggian center Balise dengan top rail, jarak center Balise dengan running rail, dan ketinggian Balise dengan bracket base. Pengukuran saat ini menggunakan alat manual seperti roll meter, meteran, dan mistar, yang rentan terhadap kesalahan. Untuk meningkatkan efisiensi dan akurasi, saya merancang alat ukur jarak balise menggunakan sensor jarak infrared laser, modul ESP32, dan OLED 0,96 Inch sebagai output, dengan data logger untuk penyimpanan data. Alat ini diuji dengan hasil menunjukkan akurasi 99,66% pada Sensor A untuk jarak balise terhadap bracket base, 99,10% pada Sensor B untuk jarak balise terhadap top rail, dan 99,94% pada Sensor C. Hasil ini membuktikan bahwa alat ukur yang dirancang mampu memberikan pengukuran yang akurat, sehingga diharapkan dapat mempermudah tim perawatan dalam pengukuran dan meningkatkan efisiensi serta akurasi dalam perawatan balise di LRT Jabodebek.

Abstract

This study examines the optimization of bottled water distribution logistics at a water company that serves eight regular customers using two Isuzu Traga Box fleets, each with a capacity of 400 cartons. The study addresses the Capacitated Vehicle Routing Problem (CVRP) by comparing three proven route optimization methods: the Saving Matrix Algorithm, the Nearest Insertion Heuristic, and the Nearest Neighbor Algorithm. The research methodology integrates exponential smoothing techniques for demand forecasting and utilizes Google Maps and Google Earth for precise distance measurements and route planning. The initial distribution system operated with 8 separate routes covering a total distance of 327.6 km, resulting in inefficient resource utilization and high operational costs. Through comprehensive optimization analysis, all three methods demonstrated significant efficiency improvements with varying performance levels. The Saving Matrix algorithm achieved the highest distance reduction of 33.67%, followed by Nearest Insertion at 33.59%, and Nearest Neighbor at 32.74%. The Saving Matrix method, selected as the optimal solution based on comprehensive performance evaluation, successfully redesigned the distribution network into 4 consolidated routes with a total distance of 220.35 km. This optimization resulted in substantial operational improvements, including: reducing delivery time from several days to 2 working days, reducing fuel consumption costs by 33.67%, and an extraordinary 60% reduction in driver meal allowances. This implementation also improved vehicle utilization efficiency and enhanced customer service reliability. The study concluded that the Saving Matrix Algorithm provides the most effective and practical solution for improving distribution logistics efficiency in the bottled water industry, offering significant cost savings while maintaining service quality standards.

Abstract

A level crossing is an intersection between a road and a railway line where the intersection is in a horizontal plane. To improve safety in railway operations, it is necessary to monitor both infrastructure, facilities, traffic and human resources. The level of safety is the main factor that is taken into consideration by service users when choosing the mode of transportation to use. Whether on land, sea or air, safety always comes first. Safety is an absolute factor that must be present in every situation, including rail transportation itself. There needs to be collaboration between parties to achieve safety at level crossings. Every level crossing has certain risks. Risk cannot be eliminated, but can be controlled. Risk control is the process of responding to and treating risks, as well as follow-up plans (Hanafi, 2006). It is necessary to identify risks as a basis for steps that must be taken by the relevant parties so that they can be controlled to reduce accidents at level crossings.

Abstract

Palembang has three main modes of transportation operating separately: river transport, Bus Rapid Transit (BRT), and Light Rail Transit (LRT). Although these modes have great potential to complement each other, the lack of proper integration results in inefficiencies in public transportation services. This study employs a qualitative approach using descriptive methods. This approach is chosen to describe and analyze the actual conditions and potential integration between river transport, Bus Rapid Transit (BRT), and Light Rail Transit (LRT) in Palembang. Data were collected from field observations, in-depth interviews with relevant stakeholders, and literature studies. Based on the integration performance measurement, the Modal Interaction Matrix resulted in a Normalized Score of -200, which falls into the poor category. Several key challenges were identified, including unintegrated infrastructure, unsynchronized operational schedules, and separate ticketing systems.
