Abstract

H-beam steel is often used as a basic material for building construction on the coast. Cases that often occur are H-beam steel that is installed quickly corrodes. This incident is caused by the coastal area belongs to an environment with a high level of corrosiveness.From the results of the pH tester test, the value of the degree of acidity is in rangeof pH=5 to pH=7.Coastal soils contain a lot of chloride Cl. In an acidic environment accompanied by a chloride Cl element, it triggers the breakdown of the passive layer on the surface which causes an anodic region to form so that the steel is in a state of releasing electrons. The problem that occurs can be overcome using a sacrificial anode cathodic protection system, with a zinc metal protection mechanism (Zn) 99, 99% which is used as a sacrificial anode has a lower potential value than the potential value of H-beam steel as a cathode protected by zinc metal (Zn) . This value of zinc metal (Zn) is more negative than the Fe steel which potential value is . The value of the potential difference is that it can be ascertained that the released Zn electrons can flow and adhere to the protected H-beam steel.

Abstract

Research on the "Effect of Magnetic Field Variations on Fuel Channels on the Efficiency of Consumption and Exhaust Emissions on Gasoline Engines" focus on how magnetic fields with various forces can increase the efficiency of fuel consumption and reduce exhaust gas emissions in gasoline -fueled engines. In this study, the magnetic field was applied to the fuel channel with the aim of affecting the combustion process in the engine. The strength variations of the magnetic field used are expected to optimize fuel combustion, so that fuel consumption becomes more economical and exhaust emissions, such as oxygen (O₂), carbon monoxide (CO), carbon dioxide (Co₂), and hydrocarbons (HC), can minimized. The results showed that the application of magnetic fields has the potential to have a significant impact on engine efficiency, especially at certain rotation, which can create environmental benefits with cleaner gas emissions and reduce overall fuel consumption.

Abstract

Injection molding is an important process in plastic manufacturing, especially for mini tray production that requires stability and severe accuracy. Temperature and injection time affect product quality, including material distribution and possible defects. This study aims to analyze the effect of these two parameters on the final weight of the product and determine optimal arrangements to achieve consistent quality. This study uses an experimental method with independent variables in the form of temperature and injection time, as well as the dependent variable in the form of product weight. Data is collected through testing with KT-105 injection molding machine and analyzed using Minitab 19 software to test the relationship between variables statistically. The results showed that the temperature and time of injection had a significant effect on the weight of the mini tray. Anova analysis proves a strong relationship between these two parameters, with a p-value value <0.05

Abstract

The automotive industry faces challenges in improving fuel efficiency and reducing exhaust emissions. One solution being developed is the Hydrocarbon Cracking System (HCS), which breaks down hydrocarbon molecules in fuel to enhance combustion efficiency. This study aims to analyze the effects of HCS on engine torque and exhaust emissions (CO, HC, and CO₂) in a four-stroke, single-cylinder gasoline engine. The research method involves an experimental factorial design of 6 × 2, testing torque and exhaust emissions at various engine speeds. Measurements were conducted using a dynamometer and a gas analyzer to compare standard conditions with HCS implementation. The results indicate that HCS increases engine torque by 3.40% and reduces CO and HC emissions by 28.12% and 54.35%, respectively. However, CO₂ emissions increased by 12.48%, indicating more complete combustion. Overall, HCS proves to enhance engine efficiency and reduce harmful emissions, making it a potential eco-friendly solution for motor vehicles.

Abstract

This study investigates the influence of tempering temperature and holding time on the flexibility of SUP9 steel leaf springs, addressing a practical need for enhanced vibration absorption in heavy-duty vehicles operating on irregular terrain. An experimental study was conducted using a full factorial design with three temperature levels (450°C, 550°C, 650°C) and three holding times (15, 20, 25 minutes). Flexibility was quantified by measuring the maximum deflection in a three-point bending test. The results demonstrate a strong, positive correlation between the tempering parameters and flexibility. The optimal flexibility (47.76 mm deflection) was achieved at the highest treatment condition of 650°C with a 25-minute holding time, representing an 83% improvement over the least effective treatment. ANOVA results confirmed that temperature, holding time, and their interaction are all statistically significant factors (p < 0.05). These findings provide a practical, data-driven guideline for manufacturing more resilient and comfortable leaf springs by optimizing heat treatment protocols.

Abstract

The increase in population means that the need for transportation is also increasing, causing more or less air pollution. Besides that, fuel oil is also a non-renewable natural resource. Oil fuel comes from plants and animals that have been dead for millions of years which have become fossils and which have been formed for a very long time  automatically become expensive. Therefore, people need vehicles that have many  advantages, including environmentally friendly, do not produce air pollution, do not produce noise, avoid traffic jams, and are easy to maintain. Flying electric vehicles are the right choice to overcome this problem. Electric car is a car driven by an electric motor that uses electric power stored in a battery. One of the advantages is that the engine construction is simpler compared to combustion engines which have so many components because there is combustion in the engine. Electric vehicles certainly need a chassis. The chassis that will be used is a tubular chassis type using fiberglass. The aim of this research focuses on planning electric flying vehicles, more precisely on static simulation of chassis design. The results of this research can be used as consideration for designing the chassis structure of flying electric vehicles. This research is expected to be the beginning of the development of an electric quadcopter flying vehicle chassis.

Abstract

This study aims to analyze the effect of the number of poles on the output power of the Permanent Power Generator (PPG). PPG is an innovative renewable energy system that utilizes permanent magnets to generate continuous electrical power without relying on external fuel sources. This study uses an experimental approach using 1 mm diameter wire and three pole configurations (3, 6, and 9 poles) to determine the optimal configuration to maximize power output. Voltage and current measurements were taken using a digital multimeter, and the power output was calculated using the formula P=V×I. The results showed that an increase in the number of poles significantly increased the generator's power output. The highest performance was achieved with a 9-pole configuration and a 1 mm wire diameter. These findings support the basic principles of electromagnetism, where a decrease in coil resistance and an increase in magnetic field frequency contribute to higher energy conversion efficiency. This study is expected to contribute to the development of environmentally friendly power generation systems and serve as a valuable reference in the design of high-power, high-efficiency generators for future renewable energy technologies.
