Abstract

Vibration testing using a shaker table vibration tester aims to determine the dynamic characteristics and the structural endurance of a test object under vibrational or shock loads. The addition of motion axes (X, Y, Z) to the shaker table through the use of a connecting link rod-type exciter allows for greater displacement of the exciter, thereby expanding the variety of vibrational movements produced by the shaker table. This configuration enables more complex and varied testing conditions, leading to more comprehensive and representative test results. This research uses the Research and Development method by making a 3-axis shaker table vibration testing machine. Using a mechanical exciter slider crank with a connecting link rod as the mechanism, and varying the value of the connecting link rod installation distance on the deviation adjustment disk by 5, 10, 15, and 20 mm from the center point to vary the amplitude of the shaker table. The results of the machine function test obtained the vibration value of the frame when the machine operates with the test object at a deviation of 5 mm, which is 16.017 rms mm/s on the X axis, 17.237 rms mm/s on the Y axis, and 13.844 rms mm/s on the Z axis, while at a deviation of 10 mm the vibration value of the frame is 7.192 rms mm/s on the X axis, 28.224 rms mm/s on the Y axis, and 22.334 rms mm/s on the Z axis. From these data, it can be identified that the vibration of the frame falls into the unsafe category according to ISO 2372 standards.

Abstract

The ratio between chicken meat and flour in the dough affects its texture, including thickness, elasticity, and ease of molding. This study aims to analyze the effect of dough ratio variations and pulley diameter sizes on the performance of a meatball (pentol) molding machine. The pulleys used were 25.4 mm (1 inch), 50.8 mm (2 inch), and 76.2 mm (3 inch), with dough ratios of chicken meat to flour at 1:1, 1:2, and 2:1. The research employed an experimental method by testing each combination to measure the number of successful molds, failures, production capacity, and molding time. The results showed that the 1-inch pulley with a 1:1 dough ratio produced the highest success rate (15 pieces), the lowest failure rate (7 pieces), and the fastest molding time (3 minutes 15 seconds). Conversely, the 3-inch pulley resulted in the slowest process (6 minutes 40 seconds) and a lower success rate. Based on these findings, it can be concluded that the smallest pulley combined with a balanced dough ratio is the most effective in improving production efficiency.

Abstract

Pada proses pembubutan, temperatur tinggi sering terjadi akibat gesekan antara pahat dan benda kerja, yang berdampak pada peningkatan keausan pahat dan penurunan kualitas hasil pemesinan. Penelitian ini bertujuan untuk menganalisis pengaruh parameter proses, yaitu kecepatan putar (spindle speed), kecepatan makan (feed rate), dan kedalaman potong (depth of cut), terhadap temperatur pahat menggunakan metode analisis variansi (ANOVA) dan regresi linier berganda. Percobaan dilakukan sebanyak 16 kali berdasarkan rancangan faktorial penuh 2³ dengan dua replikasi. Hasil analisis menunjukkan bahwa feed rate dan depth of cut berpengaruh signifikan terhadap temperatur pahat, sedangkan spindle speed tidak memberikan pengaruh yang signifikan secara individual. Namun, interaksi antara faktor-faktor tersebut terbukti memberikan pengaruh yang signifikan terhadap temperatur. Model regresi linier berganda yang dikembangkan memiliki nilai koefisien determinasi (R²) sebesar 93,99%, yang menunjukkan kecukupan model untuk prediksi. Temuan ini memberikan kontribusi dalam pengendalian parameter proses untuk meminimalkan temperatur pahat, memperpanjang umur pahat, serta meningkatkan efisiensi dan kualitas dalam proses pembubutan.

Abstract

This research analyzes the aerodynamic characteristics of the VU-EV electric vehicle using Computational Fluid Dynamics (CFD) simulation. The study evaluates airflow patterns, pressure distribution, and wake formation at three speeds (20 km/h, 25 km/h, and 30 km/h), aiming to enhance the aerodynamic efficiency and performance of a six-passenger electric golf car equipped with solar panels.The simulation results indicate that higher speeds result in more turbulent airflow, greater pressure differentials between the front and rear, and increased aerodynamic drag. For future studies, improvements in body design—especially at the rear—and the addition of aerodynamic devices are recommended to minimize drag, alongside experimental validation to ensure simulation accuracy and wider applicability for the development of sustainable vehicles.

Abstract

The use of metal or steel in a variety of applications has begun to be replaced by Carbon Fiber Reinforced Polymer (CFRP). Some of the advantages of CFRP include mechanical strength almost equal to, and sometimes exceeding, that of metal materials. One innovation in the manufacture of carbon fibre composites is the vacuum infusion method. Resin is drawn into the mould under suction pressure from a vacuum pump. Excess resin is drained from the mould through a hose and collected in a container, which also serves to control the vacuum pressure in the mould before it enters the pump. Previously, the catchpot was made of square-shaped iron with permanently welded joints, resulting in unstable suction pressure. Additionally, the resin's fast curing properties made cleaning difficult, leading to blockages in the hose over time. These issues highlight the need for a vacuum infusion design that is easy to open and close, easy to control and leak-proof. In this study, a research and development (R&D) approach was taken. The design process for the Cylinder Catchpot Vacuum Infusion begins with the design, calculation, and design stages, and ends with functional testing. The design process takes into account dimensions and the motor power required to use ¼HP for a 1-liter catchpot. The component is manufactured through the manufacturing stage and undergoes functional testing, where the Cylinder Catchpot Vacuum Infusion tool detects no leaks in the circuit, ensuring stable pressure, and ensuring proper resin distribution throughout the fibers, ensuring no voids in the composite
