Abstract

This study aims to analyze the effect of the combination of oil viscosity and shock load on the compression characteristics of telescopic shock absorbers on motorcycles, which include depth, time, and compression speed parameters. The experiment was carried out using two levels of oil viscosity, namely 10 cSt and 15 cSt (equivalent to SAE 10W and SAE 15W), as well as two shock load variations, namely 40 kg and 50 kg, which were dropped vertically from a height of 30 cm. Compression depth measurements were carried out using a slow-motion camera at a speed of 240 fps and the results were validated using Kinovea software. Meanwhile, the compression time measurement is carried out with a stopwatch, and the compression speed is calculated from the results of the comparison between the compression depth and the compression time. The experimental data were analyzed using Minitab software with the Two-Way ANOVA method to determine the influence of each variable on response. The results of the analysis showed that oil viscosity and shock load had a significant influence on the compression depth, while the viscosity of the oil also significantly affected the compression speed. However, neither the viscosity of the oil nor the shock load exerted a significant influence on the compression time. To support the results of the experiment, a mass-spring-damper system theory model approach was used, which represents the dynamic behavior of shock absorbers. This model helps to explain the compression response to changes in fluid and load parameters theoretically. Based on the analysis of experimental results and model simulations, the optimal combination that provides the best performance is found in the use of oil viscosity of 10 cSt (SAE 10W) with a shock load of 50 kg.

Abstract

This study investigates the influence of wheel rotational speed and brake pad material on the temperature of disc braking systems. The experimental setup incorporates an LM393 speed sensor and a MAX6675 thermocouple temperature sensor, both interfaced with an Arduino microcontroller, with data output displayed via a MATLAB GUI and an LCD screen. Testing was conducted in three repetitions across four rotational speed variations (1000, 1500, 2000, and 2500 rpm) and three types of brake pad materials: standard, semi-metallic, and full-metallic. The results indicate a direct correlation between rotational speed and braking temperature. At 2500 rpm, the highest temperatures recorded were 83.3°C for full-metallic pads, 59°C for semi-metallic pads, and 47°C for standard pads. These findings confirm that both the pad material and wheel speed significantly affect the heat generation during braking.

Abstract

The development of electric vehicle technology has encouraged the use of electric bicycles as an environmentally friendly and energy-efficient mode of transportation. One of the main components of an electric bicycle is the hub BLDC (Brushless Direct Current) motor, which is considered more efficient because it is directly integrated into the wheel without requiring a chain transmission system. However, the performance of the hub BLDC motor is affected by operating conditions, particularly variations in load and speed, which influence current consumption and overall electrical performance. This study aimed to analyze the effect of load and speed variations on the current consumption of a hub BLDC motor. A quantitative experimental method was employed by conducting direct tests on an electric bicycle using load variations of 50 kg, 60 kg, and 70 kg, as well as speed variations of 30 km/h, 35 km/h, and 40 km/h. Current measurements were carried out in real time using a PZEM 051 sensor, and the collected data were analyzed using average values obtained from repeated measurements. The results showed that increasing the load and speed led to higher current consumption of the hub BLDC motor, from 4.6 A to 5.0 A under load variation and from 4.5 A to 5.1 A under speed variation. These findings indicate that both load and speed significantly affect the electrical current required by the hub BLDC motor, demonstrating that greater operating demands result in higher energy consumption.

Abstract

White oyster mushrooms (Pleurotus ostreatus) represent a vital agricultural commodity and a major source of income for residents of Dusun Wiloso, Desa Gondowangi, Kecamatan Wagir, Kabupaten Malang. Despite their economic potential, the productivity of local mushroom farmers remains constrained by the conventional manual process of preparing baglog planting media, which involves mixing wood sawdust and rice bran. This traditional method is not only labor-intensive and time-consuming but also prone to inconsistencies that may damage the planting media and reduce overall yields. In response to these challenges, the Community Service Program (PPM) introduced an innovative training and technology transfer initiative focused on the design, fabrication, and utilization of a mushroom planting media mixing machine. This intervention effectively mechanizes the mixing process, thereby improving production efficiency, ensuring greater uniformity and quality of the planting media, and enhancing cultivation outcomes. Beyond its technical advantages, the program promotes local capacity building by expanding community knowledge in mechanical engineering and fabrication, fostering innovation, and stimulating entrepreneurial opportunities among local fabrication workshops. These workshops play a strategic role in sustaining the availability of appropriate agricultural technologies, supporting the continuous improvement of mushroom cultivation systems, and strengthening the region’s technological independence. Consequently, this PPM initiative not only addresses critical production bottlenecks but also contributes to broader goals of rural economic development, technological empowerment, and sustainable community self-reliance within Dusun Wiloso.

Abstract

This study of the failure of spinning roll shafts used in cone plate formation, caused by uneven stress distribution due to suboptimal geometric design. The aim of this research is to analyze the root causes of shaft failure and optimize its design using Finite Element Method (FEM). The method employed involves simulating the spinning roll shaft with various geometric dimensions, such as diameter and fillet radius, to evaluate stress distribution and identify potential failure points. The results indicate that maximum stress occurs at the shaft diameter transition and fillet radius areas, leading to stress concentration, which can cause premature failure. Design improvements, such as increasing the fillet radius and enlarging the transition diameter, significantly reduced maximum stress and enhanced the shaft's safety factor. In conclusion, the research demonstrates that shaft failure is primarily caused by geometric design flaws resulting in excessive stress concentration rather than material quality. Modifying the geometry, especially the fillet radius and diameter transition, can improve the reliability and lifespan of the shaft, thereby reducing the risk of failure in cone plate spinning processes.
