Abstract

. Composite materials have developed rapidly over the years and now play an important role in the advancement of materials technology. It is believed that the use of mixed (hybrid) composites between natural fibers and artificial (synthetic) fibers can produce better composites. This research aims to determine the effect of the arrangement of hybrid composite laminates reinforced with hemp fiber and carbon fiber using an epoxy resin matrix on mechanical properties, namely tensile strength and impact toughness. The composite was made using the hand lay up method with variations in the laminate composition, namely Carbon-Hemp-Carbon-Hemp and Hemp-Carbon-Carbon-Hemp. The hemp fiber was treated with alkali by soaking in 5% Naoh for 2 hours. The research results show that of the two specimen variations, the Hemp-Carbon-Carbon-Hemp variation has the highest tensile strength value of 245 MPa with the highest strain reaching 0.074 while the highest elastic modulus in the Carbon-Hemp-Carbon-Hemp variation is 6.04 GPa. Charpy impact testing obtained the highest impact value in the Hemp-Carbon-Carbon-Hemp variation of 0.07762 J/mm².

Abstract

Proton Exchange Membrane Fuel Cells (PEMFCs) are increasingly developed due to their high efficiency, power density, durability, and environmental friendliness. However, the high cost of platinum catalysts limits their widespread application. Reducing platinum usage through the development of low-cost catalyst support materials is a promising approach. Activated carbon derived from biomass offers a sustainable and economical alternative, particularly when utilizing agricultural waste such as coffee husks, which are often discarded. This study aims to evaluate the characteristics of activated carbon produced from coffee husk waste through pyrolysis as a catalyst support for PEMFCs. Pyrolysis was conducted at 400 °C, followed by chemical activation using 1 M H₃PO₄ and 1 M KOH with a residence time of 90 minutes. The resulting activated carbon was analyzed through proximate analysis to determine moisture content, ash content, volatile matter, and fixed carbon content. The results showed that activation with 1 M H₃PO₄ produced the lowest moisture content (3.4%), the lowest ash content (3.8%), and the highest fixed carbon content (60.5%), while 1 M KOH yielded the lowest volatile matter content (27.7%). Based on these results, activated carbon produced using H₃PO₄ meets the requirements of SNI No. 01/6235/2000 and demonstrates strong potential as a catalyst support material for PEMFC applications.

Abstract

Background: The current demands of Industry Revolution 4.0 require highly skilled vocational graduates who are skilled in the fundamental technology of automation, including pneumatic control systems. Meanwhile, SMKN 1 Windusari Mechanical Engineering have competency shortage as the school does not have physical equipment in the form of trainer kits in the field of electropneumatic. Contribution: The aim is to improve the technical skill and competency level of students in the control pneumatic systems to be able to meet industry demands as a requisite baseline of smart automation in the Industry 4.0 era. Method: Basically, this program used measurable training methodology, simulation, and hands-on. But the course process involves three stages: situation analysis, preparation, intensive and measured training (1st day: seminar, 2nd day: practical training, simulation), then evaluation and projected outcomes. Results: In quantitative terms, the program realized a gain in knowledge for the students, with the average test score increasing from 66.67 to 72.00 (grade 0-100). Qualitatively, the students can make some electro-pneumatic circuits, like stamping unit, vertical inventory, conveyor line separator, vertical inventory to storage, etc. Conclusion: This Community Service Program has successfully addressed its primary objective: the enhancement of technical competencies in pneumatic control systems as a fundamental element of smart automation in the Industry 4.0 era among SMKN 1 Windusari students.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) producing sweet potato chips in Mandiran Village, Salaman District, Magelang Regency face productivity challenges due to the manual slicing process. This method reduces production capacity, causes inconsistent slice thickness, and increases the risk of workplace accidents. Limited technical knowledge also prevents optimal use of existing slicing machines. This program aims to enhance operational capability through training on machine operation and maintenance, based on Standard Operating Procedures (SOP) and occupational safety principles. The method includes needs assessment, development of training modules, machine operation demonstrations, and evaluation of participants’ skills. The results indicate significant improvements in operational competence, work efficiency, and product consistency. The participatory approach also fosters a safer work culture and supports the sustainable adoption of appropriate technology, thereby strengthening the competitiveness of local food-based MSMEs.

Abstract

This study investigates the effect of zinc phosphate coating duration on the corrosion rate and wear resistance of ST42 steel for maritime applications. The experimental method involved immersion at 90°C with time variations ranging from 10 to 30 minutes. Corrosion rate testing utilized the potentiodynamic method (ASTM G102-89) in a 3.5% NaCl solution, while wear resistance was evaluated using the universal wear method (ASTM G99). The results indicate that the lowest corrosion rate occurred at a 30-minute coating duration (0.00678 mmpy), whereas the highest rate was at 10 minutes (0.08600 mmpy). Optimal wear resistance was observed at 20 minutes, yielding a value of 0.000642 mm³/kg·m. In conclusion, zinc phosphate coating effectively enhances the durability of ST42 steel against corrosive environments and mechanical friction. A 30-minute duration is recommended for maximum corrosion protection, providing a viable solution for extending the service life of maritime components such as anchor chains.

Abstract

This study aims to investigate the influence of overhang inclination angle and nozzle temperature on the surface roughness of the overhang section in a 3D printed object using Polylactic Acid (PLA) material with the Fused Deposition Modeling (FDM) method. An experimental approach was employed by varying the overhang angles (35˚, 45˚, and 55˚) and nozzle temperatures (210˚C, 220˚C, and 230˚C) during the printing process. Surface roughness measurements were performed on unsupported overhang areas using a surface roughness tester. The results showed that surface roughness increased with greater overhang angles and higher nozzle temperatures. The lowest surface roughness value was recorded at 210˚C with a 35˚ overhang angle, while the highest was observed at 230˚C with a 55˚ overhang angle. These findings indicate that controlling the nozzle temperature and overhang angle is crucial for achieving optimal surface quality in overhang printing. This study is expected to contribute to the optimization of FDM process parameters to produce smoother surfaces.
