Abstract

General Background: Waste management and alternative energy utilization are critical challenges in sustainable engineering systems. Specific Background: Conventional combustion systems often rely on mechanical devices such as blowers to improve combustion, which increases complexity and energy consumption. Knowledge Gap: Limited studies integrate steam boiler systems directly into combustion processes to generate airflow without additional mechanical assistance. Aims: This study aims to design and analyze a steam-assisted combustion stove using waste oil as fuel, focusing on thermal performance, steam generation, and flow characteristics. Results: The system employs a steam boiler with dimensions of 40 × 40 × 40 cm, producing steam at a rate of 0.0170 kg/s with a required heating power of 38,382 W and fuel consumption of 1.2 kg/h. Simulation results show flow velocities ranging from 52.8 m/s in the pipe to 531 m/s at the nozzle, indicating significant acceleration due to geometric constriction. Novelty: The integration of a steam boiler into a combustion system enables the conversion of thermal energy into kinetic energy flow without mechanical air supply devices. Implications: The design provides a practical solution for improving combustion performance using waste-derived fuel while maintaining system simplicity and safety. Keywords: Steam Boiler, Waste Oil Fuel, Combustion System, Flow Velocity, Thermal Design Key Findings Highlights Steam generation reached stable mass flow under defined thermal conditions Nozzle configuration created substantial acceleration in fluid stream Structural design met pressure resistance and operational safety criteria

Abstract

General Background: Automotive development increasingly emphasizes component material selection and manufacturing methods to optimize engine performance. Specific Background: Pistons are critical engine components whose production route, particularly casting and forging, may influence power and torque characteristics. Knowledge Gap: Although many studies discuss piston materials and engine performance separately, direct comparative experimental evidence between casting and forged pistons under identical operating conditions on the Yamaha Jupiter Z 2007 remains limited. Aims: This study aims to analyze the differences in power and torque generated by standard, casting, and forged pistons using dynotest measurements at 2000, 4000, 6000, and 8000 RPM. Results: The results indicate that forged pistons produced the highest overall performance, with average torque reaching 13.32 Nm at 2000 RPM and average power reaching 11.2 HP at 6000 RPM. Casting pistons occupied an intermediate position, while standard pistons consistently produced the lowest values. At high engine speed, forged pistons maintained better performance stability than casting and standard pistons. Novelty: The study directly compares three piston types within the same motorcycle platform while also relating performance differences to piston mass variation, where forged pistons showed the lightest weight. Implications: These findings indicate that piston manufacturing type is closely associated with engine output, and forged pistons offer stronger potential for applications requiring higher power and torque performance. Keywords: Forged Piston, Casting Piston, Engine Performance, Power and Torque, Dynotest Key Findings Highlights Forged pistons produced the highest output across most engine speed ranges. Peak engine capability was observed around 6000 RPM before declining at 8000 RPM. Lower piston mass was associated with stronger high-speed performance stability.

Abstract

General Background Fish crackers are a popular Indonesian snack with a simple production process but high demand. Specific Background In Pasuruan Regency, SMEs struggle with manual dough mixing, which leads to inconsistent texture and high labor costs. Knowledge Gap Current traditional methods lack efficiency and structural consistency, requiring a more robust and hygienic automated solution. Aims This study aims to design and validate an automatic fish cracker dough mixing machine using static load simulations. Results The selection process using a morphological chart led to Concept A, which utilizes a 0.37 kW motor and stainless steel components. SolidWorks 2016 simulations revealed a maximum von Mises stress of 14.224 MPa and a maximum displacement of 8.74 mm under a 92 Nm torque load. Novelty The research introduces a highly stable frame structure (50x50x3 mm profile) with a safety factor of 13, significantly exceeding standard safety requirements for SME equipment. Implications This innovation allows for consistent 10 kg batch production, reducing manual labor and increasing the profit potential for local food industries. Keywords Dough Mixer, Fish Crackers, Morphological Chart, Static Simulation, Safety Factor Key Findings Highlights Concept A was selected as the optimal design using a systematic morphological chart and FEA validation. The frame structure achieves a safety factor of 13, ensuring high durability for small-scale industrial use. The automated system replaces manual labor with a 0.37 kW motor capable of handling 10 kg loads efficiently.

Abstract

General Background: Dissimilar metal welding is widely used in industrial applications where different materials are combined to balance mechanical strength, corrosion resistance, and economic efficiency. Specific Background: Carbon steel ASTM A36 provides good strength and low cost, while stainless steel 316 offers superior corrosion resistance, making their combination attractive for structural applications. Knowledge Gap: Although dissimilar metal welding has been widely studied, limited experimental data directly compare the effects of welding current and cooling media on tensile properties and macrostructure in ASTM A36 and stainless steel 316 joints using stainless steel electrodes. Aims: This study aims to analyze the effect of welding current and cooling conditions on the tensile strength and macrostructure of dissimilar metal welded joints. Results: Nine specimens were welded using current variations of 70 A, 80 A, and 90 A with air, natural air, and oil cooling. The highest stress value was 389.060 Kgf/mm² at 90 A with oil cooling, the highest strain value was 0.039 at 90 A with oil cooling, and the highest elastic modulus was 11,610 Kgf/mm² at 90 A with natural air cooling. Macrostructure observation showed that the 90 A natural air specimen had no visible welding defects, while the 70 A water-cooled specimen showed porosity, underfill, arc strike, and slag inclusion. Novelty: The study directly compares current variation and cooling media simultaneously in dissimilar metal welding between ASTM A36 and stainless steel 316. Implications: Proper current selection contributes to better tensile performance and improved weld quality in dissimilar metal joining applications. Keywords: Dissimilar Metal Welding, Welding Current, Tensile Strength, Macrostructure, ASTM A3 Key Findings Highlights The 90 A parameter produced the most favorable overall mechanical response. Defect-free weld morphology appeared under natural air cooling at high current. Lower current generated more visible discontinuities in the welded region.
