Abstract

Adhesive bonding has become one of the most widely used joining techniques in engineering due to its ability to provide uniform stress distribution, minimize structural weight, and avoid the thermal distortion during welding processes. This study examines the effect of carbon black weight fraction on the shear strength of aluminum single-lap joints bonded with polyurethane adhesive. Aluminum 6061 specimens were prepared following ASTM D1002 standards and were reinforced with carbon black at weight fractions of 0, 8, 16, and 24 wt%. Fourier Transform Infrared (FTIR) spectroscopy was conducted to identify any chemical interactions, and lap shear testing was performed using a Universal Testing Machine (UTM). The results indicated that increasing the weight fraction of carbon black enhanced the shear strength and gradually shifted the failure mode from adhesive failure to cohesive failure. The specimen containing 24 wt% of carbon black exhibited the highest shear strength of 2.81 MPa, with 88% of the failures occurring cohesively. FTIR analysis revealed that carbon black did not introduce any new functional groups but functioned as a physical reinforcing filler within the polyurethane matrix. Therefore, carbon black is an effective reinforcing material for improving the mechanical performance of polyurethane adhesive-bonded aluminum single-lap joints.

Abstract

Particleboard is a composite material based on lignocellulose that can be produced from agricultural waste, serving as an alternative to traditional wood products. This study utilized waste from oil palm fronds and empty fruit bunches as raw materials for the production of particleboard. The oil palm fronds were processed into filler particles of varying sizes: 80-mesh, 60-mesh, and 35-mesh. The composition of the raw materials included 50% oil palm frond particles, 15% empty fruit bunch fiber, 20% PVAc adhesive, and 15% epoxy resin. The particleboard was manufactured using a single-punch cold-press process at a pressure of 0.30 MPa for 120 minutes, followed by curing at 150°C for 60 minutes. Various characteristics of the particleboard were tested, including density, water content, thickness swelling, modulus of rupture (MOR), and modulus of elasticity (MOE). The results indicated that the particle size of 80-mesh yielded the best properties, with a density of 0.88 g/cm³, a water content of 5.51.6%, thickness swelling of 1.13%, a MOR of 19.79 MPa, and a MOE of 1.08 GPa. All specimens met the standards set by SNI 03-2105-2006 for density, water content, thickness swelling, and MOR; however, the MOE value did not meet the required standards.

Abstract

Cassava (Manihot esculenta Crantz), also known as tapioca or cassava, is one of the main tuber crops cultivated in humid tropical regions. In addition to being a staple food source, cassava is also used to produce tapioca flour and cassava chips through a shredding process. Cassava shredding can be done manually with traditional tools or made easier by using technology in the form of a shredding machine. However, the use of shredding machines still faces obstacles such as relatively long time and uneven shredded results. This machine is designed to increase the quantity and quality of shredded results. Horizontal knives and spring-shaped pushers are used in the machine. The way this machine works is by rotating the blade using a 125 watt electric motor, using 2 blades and machine dimensions of 60 cm long x 30 cm wide x 40 cm high. The results of this study were carried out 3 times, obtaining an average yield of 886 grams and an average time of 80.41 seconds with a production capacity of 40.636 kg / hour and a production efficiency of 88.6%.

Abstract

The process of bending steel pipes in making classroom table frames in many workshops is still carried out manually, resulting in less precise bending angles, inconsistent product quality, and low work efficiency. This study aims to design and make a jig and fixture for bending steel pipes as a tool to assist in the classroom table frame manufacturing process by applying the VDI 2222 method. The research stages include literature review, needs analysis, concept design, selection of design alternatives, making the tool, and testing the tool's performance. The testing was conducted on several types of steel pipes, namely galvanized pipes with thicknesses of 0.9 mm and 1.7 mm, as well as ST37 pipes with thicknesses of 1.4 mm and 1.7 mm. The results show that the designed jig and fixture can bend steel pipes up to a 90° angle while keeping the pipe stable during the bending process. The material and thickness of the pipe affect the quality of the bending results, where the thicker the pipe, the greater the force required and the higher the potential for wrinkles to form on the inside of the bend. A 1.4 mm thick ST37 steel pipe produces bending quality that is most suitable for making classroom table frames. Overall, the designed tool has fulfilled its function as a steel pipe bending aid, although further development is still needed on the forming and holding system to reduce bending defects and lower the operating force.

Abstract

One of the factors influencing the performance of the can-pressing machine is the motor speed. This study aimed to determine the effect of machine rotational speed variations on the final height of compressed aluminum cans and the pressing time required. The experiments were conducted using a can-pressing machine powered by a 1 HP electric motor with rotational speed variations of 1200 rpm, 1300 rpm, and 1400 rpm. Each rotational speed was tested in three trials using 10 used aluminum cans as test specimens. The observed parameters were the final height of the cans after pressing and the time required for the pressing process. The results showed that the machine rotational speed significantly affected both the compression height and the pressing time. At 1200 rpm, the average final can height was 18.87 mm with an average pressing time of 36.67 seconds. At 1300 rpm, the average final can height decreased to 17.47 mm with an average pressing time of 20.67 seconds. Meanwhile, at 1400 rpm, the average final can height was 17.02 mm with an average pressing time of 16.67 seconds. These findings indicate that increasing the machine rotational speed results in a lower final can height and a shorter pressing time. Compared with the manual pressing method, which produced a final can height of approximately 30 mm and required about 70 seconds, the machine-assisted pressing process proved to be more effective and efficient. Based on the results of this study, it can be concluded that a rotational speed of 1400 rpm is the optimal operating condition, as it produced the smallest final can height and the shortest pressing time. Therefore, increasing the machine rotational speed within the tested range can improve the quality of the compression results and enhance the efficiency of the used aluminum can pressing process.

Abstract

Designing a pipe bending jig and fixture by applying the stages of the VDI 2222 method, so that a design suitable for the production process of class chairs is obtained. At this stage, written data regarding the bending of ST37 pipes and research results using the VDI 2222 research method are collected from reputable sources such as journals, books, research reports, scientific papers, and articles. From the bending results, it can be concluded that the ST37 pipe responds quite well when bent using this tool, producing good bends and only experiencing slight ovalization compared to other pipes. Therefore, this 1.4 mm diameter ST37 pipe becomes the best product choice compared to other ½-inch pipes. Based on the analysis of the tool I designed and built, it can be concluded that the tool using the VDI 2222 method is capable of bending ST37 pipe with a diameter of 1.4 mm shows quite good bending results, only experiencing slight ovalization.

Abstract

The engine hood of the prototype electric vehicle, developed in a previous study, still uses a permanent mounting system, which limits access for inspection and maintenance of the vehicle’s front compartment. This study aims to implement an opening-closing system and a reinforcement structure for the hood using 1 mm-thick Steel Plate Cold Commercial (SPCC). The research was conducted through the following stages: design using SolidWorks 2022; fabrication of the hood panel and reinforcement structure; assembly of the opening-closing mechanism components; and evaluation of the implementation results. The opening-closing mechanism consists of a hood hinge, a hood latch, and a hood support rod, while the reinforcement structure was fabricated using a 25 × 25 × 2 mm hollow square  profile. The results of the study indicate that the opening-closing system and the reinforcement structure were successfully implemented according to the design, forming a single structural unit with the hood panel. The reinforcement structure serves to strengthen the panel while also acting as a mounting bracket for the hood hinge and hood latch, whereas the implementation of the opening-closing system improves ease of access to the vehicle’s front compartment for inspection and maintenance compared to the previous design, which used a permanent mounting system. Furthermore, the development of the hood enhances functionality without altering the primary dimensions or the basic concept of the front body of the prototype car.

Abstract

Metroxylon sago is a palm that grows widely in tropical wetlands and has high economic and ecological value. The sago stem pulp waste contains cellulose fibers that have potential as reinforcement in composite materials. However, the hydrophilic nature and surface impurities of natural fibers limit their mechanical performance. Therefore, this study aims to analyze the effect of liquid smoke treatment on the morphology and tensile strength of single fibers from sago stem pulp. This study used an experimental method. The fibers were soaked in coconut shell liquid smoke for 1, 2, and 3 hours, followed by drying in an oven at 40°C for 30 minutes. Morphological observations were performed using a JEOL JCM 6000 Scanning Electron Microscope, and single fiber tensile tests were conducted according to ASTM D3379-02 standard. The results were compared with untreated fibers as control. The results showed that liquid smoke treatment altered the fiber morphology in all treatment variations. The most optimal surface morphology was obtained at 1 hour of treatment, characterized by a cleaner and rougher surface due to the removal of hemicellulose and impurities. In terms of mechanical properties, liquid smoke treatment increased the tensile strength of single fibers. The highest tensile strength was achieved at 1 hour of treatment with a value of 49.232 MPa, while the lowest was at 2 hours of treatment with 16.694 MPa. Prolonged soaking beyond 1 hour caused fiber degradation and a decrease in tensile strength. It can be concluded that 1 hour of liquid smoke treatment is the optimum duration to improve the morphology and tensile strength of single sago stem pulp fibers. This treatment can be used as an environmentally friendly alternative to enhance the quality of natural fibers for composite reinforcement applications.

Abstract

Utilising oil palm frond fibre and eggshell powder provides an opportunity to convert plantation and food waste into functional composite constituents. This study examined the effects of fibre length and eggshell-powder content on the Charpy impact strength of a polyester-matrix composite. A 3 × 3 full-factorial design was applied using fibre lengths of 60, 70, and 80 mm and eggshell-powder contents of 3, 6, and 9 wt.%. Three specimens were prepared for each combination by hand lay-up, giving 27 specimens, and were tested with reference to ISO 179-1. The highest mean impact strength was 50.72 kJ/m² for the 80 mm–9% combination, whereas the lowest was 15.52 kJ/m² for the 80 mm–6% combination. Two-way ANOVA indicated significant effects of fibre length, eggshell-powder content, and their interaction (p < 0.001). The interaction confirms that a longer fibre does not automatically improve impact strength unless it is accompanied by an appropriate filler content. The investigated composite is therefore positioned as an initial candidate for car bumper components.

Abstract

The use of environmentally friendly composite materials has been increasingly developed as an alternative to conventional materials for automotive components. This study aimed to investigate the effect of stacking sequence variations on the thermal insulation performance and impact strength of Green Sandwich Composites reinforced with coconut coir fiber, woven fiberglass, a balsa wood core, and polyester resin. The specimens were fabricated using the hand lay-up method combined with vacuum bagging, followed by thermal insulation and Charpy impact testing. The data were analyzed using One-Way ANOVA. The results showed that the GF–NF–C–NF–GF configuration exhibited the best performance, achieving a thermal insulation efficiency of 40.65% and an impact strength of 198.98 kJ/m². However, the One-Way ANOVA results indicated that stacking sequence variations had no statistically significant effect on either parameter at a 5% significance level. Nevertheless, the GF–NF–C–NF–GF configuration is recommended as the optimum stacking sequence because it provides the best combination of thermal and mechanical performance for environmentally friendly automotive bumper applications.
