Evacuation routes are important component during evacuation process, but sometimes the evacuation route conditions are not ready to use for evacuation. The good evacuation route can be seen from various aspects including width, pavement conditions and associated with the load or density during the evacuation process. An evacuation route need to optimize, but it is very difficult, due to time and cost constraints that cause not all available routes become good choices during evacuation. So it is necessary to select a good route for evacuation. In this study, the best evacuation routes are select using AHP method to analyze the priority of evacuation route. The criteria including the shortest distance and pavement conditions. Of the 20 available routes, seven routes are becomes recommended evacuation route. This research provides practical recommendations for improving road conditions and increasing capacity on specific routes to enhance evacuation efficiency in the disaster-prone areas of Merapi.

Jalan Margonda Raya is a primary collector road in Depok City that plays a vital role in urban traffic movement. The high volume of vehicles, especially during peak hours, often leads to significant congestion. This study aims to analyze traffic performance on the road segment based on the Indonesian Highway Capacity Guidelines (PKJI, 2023) and to evaluate the application of Artificial Intelligence (AI) in traffic surveys to improve data accuracy and minimize bias commonly found in conventional methods. The survey was conducted on weekdays, and the analysis showed that the highest traffic volume reached 4,161 pcu/hour, with a total vehicle count of 10,465 pcu/hour and an average speed of 31 km/h. The degree of saturation (DS) was recorded at 0.90, indicating a Level of Service (LOS) E—an unstable traffic condition approaching maximum capacity. The peak traffic period occurred between 06:45 and 07:45 AM. The implementation of AI in traffic surveys proved to deliver efficient and reliable results, offering an innovative alternative to support decision-making in transportation planning.

This study evaluated the impact of using turpentine oil as an additive in gasoline fuel mixtures on exhaust emissions. Turpentine oil, obtained from pine tree resin, has flammable properties and high oxygen content, which is believed to be able to improve the combustion process in the engine. In this experiment, gasoline was mixed with turpentine oil in various concentrations (0%, 5%, 10%, 15% and 20%) and tested on a single-cylinder 4-stroke gasoline engine with engine speeds (1500, 3000, 4500 and 6000) rpm. The emissions analyzed included carbon monoxide (CO), hydrocarbons (HC), carbon dioxide (CO₂), and oxygen (O2). The results showed that the addition of turpentine oil in certain amounts could reduce CO and HC emissions at engine speeds above 4000 rpm due to more perfect combustion, although accompanied by a slight increase in CO2 and O2 emissions at engine speeds above 4000 rpm. Overall, turpentine oil shows potential as an environmentally friendly alternative additive in reducing emission pollution from gasoline fuel.

Tires are a vital component of a motor vehicle that serves to minimize vibrations caused by uneven road surfaces, stabilizing the vehicle on the road and facilitating the driver's control over the vehicle's direction. Tire pressure that does not meet standard specifications will affect the braking performance, making it suboptimal, which can result in less effective vehicle braking. This research will discuss the influence of varying wind pressure in tyres on the effective braking distance of Honda Supra X 125 cc motorcycles to prevent accidents caused by tyre blowouts. In this test, the author will compare three (3) variations of tire pressure at the front tire position, namely 20, 29, and 40 Psi. The initial speed of the vehicle in this test is 40 km per hour and 60 km per hour, until the vehicle comes to a stop. This test is limited to dry road surface conditions and the rear tire pressure is kept the same at 33 Psi. From the results of the test, we can conclude that the best (shortest) braking distance at initial speeds of 40 km per hour and 60 km per hour is still better at a tire pressure variation of 29 Psi (in accordance with the guidelines of the manual book or the standards of Honda motorcycle manufacturers).

Accidents occur on various road terrains that cause drivers to experience losses from property to fatalities. Prof. Hamka Street and Siliwangi Street are located in the city of Semarang where Prof. Hamka Street is a road with a hilly topography while Siliwangi Street is a flat road. Problems occur on these road sections such as the many accidents that result in fatalities. The existing problems need to be addressed immediately so that they can reduce the risk of accidents in the future. The stages carried out first analyze the characteristics of accidents and vulnerable locations so that they know the most appropriate handling points and recommendations. In determining the location points prone to accidents using the EAN and UCL methods while in identifying the hazards of vulnerable locations using HIRARC. The results obtained on Prof. Hamka Street, the location points are at STA 6 (0 + 700) and 9 (1 + 000) while on Siliwangi Street, the location prone to accidents is at STA 18 (1 + 900) and 5 (0 + 600). The recommended handling is to repair the condition of the road surface that has cracks at the joints, signs at accident-prone locations that are still very lacking, street lighting at accident-prone locations, maintenance on the road so that obstacles on the side of the road do not block visibility and installation of vehicle speed control devices.

This study aims to analyze the contribution of human error factors to traffic accidents in Bali using a mixed-method approach with a convergent triangulation design. Data were collected from three main sources: traffic accident records from the Bali Regional Police for the 2023–2024 period, a survey of 166 respondents, and in-depth interviews with five road safety experts. Quantitative analysis was conducted through statistical descriptions, Incident Rate per Million Vehicle Kilometers (IRMS), and assessment of public understanding levels, while qualitative analysis was carried out using a thematic approach supported by ChatGPT software. The results show that the majority of accidents occurred in Denpasar, with victims predominantly in the young adult age group (20–29 years), with senior high school education or equivalent, and without a driver's license. The most common type of accident was single-vehicle crashes involving motorcycles, occurring on collector roads in the afternoon, under clear weather and good road conditions. The survey revealed that only 3 out of 9 aspects were well understood by most respondents, indicating the need for public outreach regarding age, occupation, driver behavior, road conditions, road geometry, and weather. Expert interviews emphasized the importance of education through direct outreach, mass media, improved infrastructure, and stricter law enforcement. This study highlights the need for systemic and educational interventions to reduce the contribution of human error to traffic accidents in Bali.

One solution to make the combustion that occurs in a motorbike closer to perfect is by utilizing the use of a Voltage Stabilizer. The performance of the Voltage Stabilizer is able to focus the electric current from the coil, so that the sparks emitted by the spark plugs are greater than before. Through the measurement results, in the condition of the Voltage Stabilizer installed, the lowest CO level was 0.72%vol, the lowest CO2 was 6.06%vol, the lowest HC was 1336 ppmvol occurred at an engine speed range of 5000 rpm. The lowest O2 level of 6.25%vol was obtained at an engine speed of 5000 rpm when the standard condition was without the Voltage Stabilizer installed. The highest O2 level obtained was 17.12%vol at an engine speed of 1000 rpm with the Voltage Stabilizer installed. The highest Torque (T) value was 8,722 Nm, and the highest Power (P) value was 8,414 PS at an engine speed range of 8000 rpm. Occurred when the Voltage Stabilizer was installed. With the installation of Voltage Stabilizer, it causes an increase in the Torque value of 11.93% and Power of 12.80% produced. The highest Fuel Consumption value of 0.642 Kg/h when the engine speed is in the range of 8000 rpm, occurs in conditions without the Voltage Stabilizer installed. The lowest Fuel Consumption value of 0.094 Kg/h when the engine speed is in the range of 1000 rpm, occurs in conditions with the Voltage Stabilizer installed. Furthermore, the installation of the Voltage Stabilizer causes a decrease in the Fuel Consumption value of 14.22%. This happens because the installation of the Voltage Stabilizer can stabilize the current and voltage obtained from the Battery/Accu to be distributed to the electrical components of the vehicle, so that there is efficiency in the vehicle's electrical supply, affecting emissions and fuel consumption produced.

The use of an Oil Catch Tank (OCT) is intended to optimize the clean air entering the intake manifold and reduce vehicle exhaust emissions. The main function of the OCT is to prevent oil particles or oil vapors from re-entering the intake system. Blow-by gases from the crankcase first enter the OCT tube, where they are trapped by a filter medium (steel wool), allowing only clean air to reach the combustion chamber. From the experimental results, across all OCT filter variations, the lowest CO levels were recorded at 1000 rpm, while the highest CO occurred at 3500 rpm. The highest CO level of 20.97% vol was found under standard vehicle conditions at 4500 rpm. The lowest HC value of 93.57 ppm vol was obtained using a 0.5-micron OCT filter at 5000 rpm. The highest torque and power values of 143 Nm and 108.65 HP, respectively, were achieved when using a 1-micron filter OCT at 6000 rpm. This study confirms that OCT installation can significantly reduce exhaust emissions and improve engine performance. These findings contribute to addressing global environmental concerns, particularly air pollution and climate change caused by the transportation sector. Furthermore, the results support the broader adoption of environmentally friendly automotive technologies, especially in enhancing combustion efficiency and emission control in internal combustion engine vehicles.

Growth in the number of vehicles, especially in urban areas, has a significant impact on traffic density, especially during peak hours, so an approach is needed to group traffic conditions based on the volume of all types of vehicles and the degree of saturation using the K-Means Clustering algorithm. The data used are the volume of all types of vehicles and the degree of saturation obtained from the Surabaya City Transportation Agency. The clustering results show that there are 4 clusters of different traffic characteristics, such as the volume of 2-wheeled vehicles during heavy traffic conditions of more than 4700 vehicles with a degree of saturation of more than 0.45. Evaluation using the silhouette coefficient produces a value of 0.63, which means the quality of the cluster is in a medium structure. This study shows that the clustering method is effective in understanding traffic conditions, although additional features can be done to optimize the quality of the cluster.
