Abstract

combustion system, especially in the cylinder head gasket, which regulates the flow of fuel and air into the combustion chamber. A common problem is leakage due to imprecision, affecting compression pressure, engine performance, and potentially causing overheating. This research aims to analyze the temperature effects on cylinder head gaskets using the finite element method and to recommend appropriate thermal loads.The study employs a clinking method where a machine moves a ram to a die, pressing sheet metal to shape the gasket, followed by a blanking stage. Analysis is conducted using SolidWorks 2022. Results indicate that temperature significantly affects the gasket's strength. As temperature rises, the gasket's strength decreases. Stainless steel, the material used, expands with higher temperatures, altering dimensions and impacting the safety factor. The higher the temperature, the lower the strength and safety factors of the cylinder head gasket.This research highlights the crucial role of temperature in the design and material selection for cylinder head gaskets. Ensuring that gaskets can withstand thermal loads is essential for maintaining engine performance and preventing issues like overheating. By understanding the relationship between temperature and gasket strength, better materials and designs can be developed to enhance durability and reliability in internal combustion engines.

Abstract

The welding process is widely used for joining in machine construction and steel construction. One popular welding method today is SMAW. SMAW welding is effective and practical because it only requires simple tools and electrodes in its use. The purpose of this study is to determine the effect of different welding currents on the cooling liquid on the welding results of SS400 steel material. This study uses SMAW welding with an E6013 Ø2.6mm electrode and SS400 steel material. After welding, the specimens were immersed in cooling liquids, namely 10% dromus, radiator coolant, and SAE 40 oil. The results of the research on the SMAW welding process for SS400 steel showed that immersion using SAE 40 oil produced the highest tensile strength at both 80A and 90A currents, which were 28.79 kg/mm2 and 28.22 kg/mm2, respectively. Meanwhile, the bending test results showed two different outcomes: at 80A current, immersion welding using radiator coolant produced the highest bending strength at 1067.77 kgf/mm2, whereas at 90A current, immersion welding using dromus produced the highest bending strength at 1130.22 kgf/mm2.

Abstract

A ship's steering system contains steering gear auxiliary machinery which functions to move the rudder or rudder when maneuvering the ship where the ship's rudder is located at the stern of the ship behind the propeller. This research aims to test the MG995 servo which is used to move a simulated ship's rudder to measure the time and accuracy of the angle of rotation of the rudder with various load variations in accordance with Solas rules. This research is a continuation of the previous research roadmap regarding sensor comparison for ship steering simulations. The capabilities of the MG995 servo were tested by comparing several loads to test stall torque conditions and the ability to move the ship's rudder. The equipment used in preparing this ship steering simulation includes a rudder to determine the position towards the port side and starboard side, an Arduino as control equipment, a rotary encoder to determine the rudder angle, a servo to move the rudder, and a rudder to test the load on the servo.

Abstract

When constructing wind turbine blades, one of the challenges is deciding on the number of blades, which in turn requires determining their height and diameter. Wind turbine blades need to be structurally sound so that they can spin with minimal wind forces. The primary objectives of this study are to ascertain the wind turbine blade height, diameter, form (specifically, helical type), and number of blades. Literature review, shaft and blade design, analysis, and discussion are all components of the design technique that the research employs. The design findings showed a wind turbine with a 2,280 mm blade height, a 1,820 mm blade diameter, a 13 mm shaft diameter, and a 90° twist, all at a low wind speed of 4.3 m/s.

Abstract

The municiple solid waste problem currently facing Kalianda City is the lack of appropriate technology that is effective and efficient. This research aims to analyze the characteristics of Kalianda city waste and its feasibility as an alternative energy source by applying appropriate technology. Surveys and investigations of waste generation volume, composition and characteristics have been carried out referring to SNI 19-3964-1994. Characterization of analytical tests such as mouister content, ash content, volatile matter, fixed carbon and chemical elements to calculate the heating value. The measurement results show that the average waste generation in Kalianda City is 0.39 kg/person/day with a composition of 65% organic waste and 35% anorganic waste. Organic waste has a mouister content of 63.05%, ash content of 16.29%, volatile matter of 70.48%, and produces fixed carbon of 44.26%. Empirical calculations after drying the waste until the mouister content was <10%, obtained a calorific value of 4,017.69 kcal/kg to 4,140.62 kcal/kg. The application of torrefaction technology results in an increase in the heating value of up to 5,424.60 kcal/kg to 5,623.29 kcal/kg equivalent to subbituminous coal B which can be used for thermal and electricity generation. The technology is economical, sustainable and uses a relatively small area.

Abstract

This study aims to analyze the effect of increasing the number of blades on a vertical axis wind turbine on the torque and power generated using the NACA 0018 airfoil. The need for efficient and sustainable renewable energy sources underscores the importance of wind turbines in the energy sector. In wind turbine design, the number of blades is a critical factor that influences the turbine's performance and efficiency. Therefore, this research focuses on understanding how variations in the number of blades affect key performance parameters such as torque and power. Simulations were conducted using ANSYS software at wind speeds of 3 m/s, 5 m/s, and 8 m/s over 10 seconds, testing blade configurations of 2, 3, 4, and 5 blades. At 3 m/s and 5 m/s, the three-blade turbine produced the highest torque and power, with maximum values of 0.358271 Nm and 5.0073110 W at 3 m/s, and 0.99525 Nm and 20.83626 W at 5 m/s.At high wind speeds (8 m/s), the two-blade turbine showed excellent performance with a maximum torque of 1.806616 Nm and maximum power of 38.36925 W. The five-blade turbine had stable performance across all wind speeds but came with higher production and maintenance costs. The four-blade turbine offered intermediate performance, better than the two-blade but less efficient than the three-blade setup. This study concludes that the three-blade turbine is most efficient for low to medium wind speeds, while the two-blade turbine performs best at high wind speeds.

Abstract

AISI 4140 steel is a low-alloy steel widely applied in the manufacturing industry due to its good combination of strength, toughness, and wear resistance. To optimize its mechanical properties, proper heat treatment processes are necessary. Previous research has shown that variations in tempering temperature can affect the size and distribution of carbides, which in turn impacts the tensile strength of the steel. Additionally, the choice of cooling media influences the cooling rate and, consequently, the final microstructure and mechanical properties. In this study, the influence of heat treatment tempering temperature variation and cooling media on the tensile strength of AISI 4140 steel is relevant. This research employs an experimental method by varying the heat treatment tempering temperature and cooling media to compare the tensile strength of AISI 4140 steel under different heat treatment conditions. In this study, specimens were divided into two variation categories: specimens heated to 175°C and 250°C (heat treatment tempering). The tensile stress graph shows that the material tempered at 175°C in water achieved a high stress value of 2047.75 MPa, while the material tempered at 250°C in oil achieved 1793.51 MPa. For strain, the material tempered at 175°C in water achieved a high strain value of 13.28%, while the material tempered at 250°C in oil achieved a low strain value of 12.34%. From the results obtained, it can be concluded that for the tensile strength of AISI 4140 steel, the highest stress value was obtained for the material tempered at 175°C in water, and the lowest stress value was obtained for the material tempered at 250°C in oil. For strain, the highest value was obtained for the material tempered at 175°C in water, and the lowest value was obtained for the material tempered at 250°C in oil.
