Abstract

The braking system is a crucial component in a vehicle, where its performance is highly influenced by the wheel's rotational speed and the geometry of the brake pad. This study aims to analyze the impact of wheel rotational speed and variations in pad geometry on the temperature of the brake pad. The braking process generates heat due to friction, which, if not properly managed, can reduce braking performance and accelerate brake pad wear. The experiment was conducted at four levels of wheel rotational speed: 1000 RPM, 1500 RPM, 2000 RPM, and 2500 RPM. The testing system was designed using a braking system simulator equipped with a speed sensor (LM393) and a temperature sensor (K-type thermocouple), which were connected to an Arduino microcontroller and displayed in real-time through a Graphical User Interface (GUI) in MATLAB. The test results indicated that both the geometric shape of the brake pads and the wheel rotation speed significantly affected the resulting temperature. Standard brake pads produced the highest temperature at a speed of 2500 RPM, reaching 63.33°C. In contrast, brake pads with holes offered the best performance by maintaining a lower temperature of only 43.00°C. Furthermore, an increase in wheel rotation speed led to a noticeable rise in temperature; for standard pads, the temperature increased from 36.67°C at 1000 RPM to 63.33°C at 2500 RPM. This demonstrates that RPM is a major factor in heat generation due to friction. The MATLAB GUI effectively visualized the relationship between RPM and temperature, facilitating the analysis and evaluation of the data.

Abstract

FCAW welding is an automated welding process that employs a wire roll electrode to melt metal, using flux or powder within the electrode's core for protection. A common issue with FCAW welding is the occurrence of angular distortion and alterations in the length and width dimensions, particularly in thin plate iron materials, due to residual stresses from the welding process. This research aims to assess the impact of static thermal tensioning, preheating, and their combination on angular distortion in SS400 steel corner joints during FCAW welding, considering heat input during welding. True experimental research methodology was employed, with variations in preheating temperatures of 200°C, 250°C, 300°C, static thermal tensioning at 150°C, 200°C, 250°C, transient thermal tensioning at 150°C, 200°C, 250°C, and a reference method with no treatment to determine the welding approach that minimizes angular distortion. The material used was 3mm thick SS400 steel. Data analysis was performed using Minitab 18 software and the One-Way Anova method. The research results indicate a significant influence of static thermal tensioning, preheating, and their combination on angular distortion. The optimal welding methods identified are preheating-static thermal tensioning at 89°55', preheating-transient thermal tensioning at 89°50', static thermal tensioning at 150°C at 89°45', transient thermal tensioning at 150°C at 89°40', and preheating at 200°C at 89°35'.

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.

Abstract

The installation and training of CCTV security systems at Pondok Pesantren Putra Baitul Qur'an Al-Khusyu Malang aimed to improve both security and the technical skills of students. The training covered the basics of CCTV technology, including installation methods, system components, and maintenance procedures, enhancing students' knowledge and preparing them for the job market. The hands-on approach proved effective, as participants were actively involved in the installation and configuration of CCTV systems. Before the training, only a small percentage of students were familiar with CCTV technology, but post-training assessments showed a significant increase in knowledge. This program not only contributed to a safer environment within the pesantren but also provided valuable technical skills that students could use in their careers or entrepreneurship. Despite challenges such as limited resources and infrastructure, the training successfully empowered the students with skills relevant to modern security needs. This initiative sets a model for other educational institutions to integrate technical training with religious education, fostering a more skilled and competitive generation

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

The Sumberingin Baths, a prominent landmark of Wringinsongo Village, represent one of the region’s most promising tourism destinations, supported by facilities such as photo spots, food stalls, places of worship, and gazebos for visitor comfort. Since 2022, the site has been enriched through the installation of an Archimedes Screw Turbine Micro Hydroelectric Power Plant (MHPP) as an educational display under the DIPA Swadana Partnership Community Service program. In 2023, the same initiative facilitated the construction of a café whose architectural design uniquely integrates natural and scientific elements, offering visitors a rare and engaging thematic experience. Despite these developments, the area remains limited in mechanical attractions that combine education with entertainment. Addressing this gap, the 2024 DIPA Swadana Regular Competition Community Service program introduced the installation of a rhythmic water wheel that harmonizes nature and technology. Designed as both a visual centerpiece and an interactive learning medium, the water wheel transforms water flow into rhythmic motion by driving musical instruments, thereby creating an innovative educational adventure that blends natural beauty with technological insight.
