Abstract

FSSW is a variation of FSW developed in metal processes. The principle of FSSW is rotating an object that is wear-resistant and then rubbed with a plate joint. The use of FSSW can be utilized in the installation of rivets such as in the drilling process, so this process needs to be investigated. This is because the heat caused by rotation will change the mechanical properties of the material so further research is needed. In this study, a connection performance comparison was made between the FSSW method and the drill. The plate used is aluminum 7075-T6 with a lap joint connection type. To find out each performance, a shear test, hardness test, and metallographic test were carried out. From the results of the shear strength test, it can be concluded that the FSSW variation is the best with an average shear strength value of 755,190 MPa, while the drill variation has an average shear strength value of 470,227 MPa. The average value for drill variations in the HAZ area was 185.06 while for the FSSW variation, it only reached 147.75. The macro test results proved that the cause of the shear strength in the FSSW was greater than that of the drill, this was caused by the difference in the size of the rivet diameter due to the use of a bad rivet gun. Meanwhile, based on the results of micro photos, the size of the structure in the HAZ area will be relatively longer than the RAW section, this is caused by friction between the tool and the workpiece

Abstract

Gondang Hamlet, Donokerto Village, faces challenges in accessing clean water, especially during the dry season, as the main water source comes from a turbid river flow. This community service initiative aims to address the issue by implementing a simple water filtration technology using a combination of media such as silica sand, zeolite, activated carbon, and magnesium. The design, training, and installation processes were carried out collaboratively with local residents to ensure sustainable usage. The results showed an improvement in water quality after filtration, although there was a challenge in the form of reduced water flow, which was resolved by installing an additional pump. This program also emphasizes the involvement of the community in maintaining the equipment and conducting regular monitoring to ensure the long-term functionality of the system. Keywords: clean water, filtration device, community service, zeolite, activated carbon

Abstract

The Dawis41 Women's Farmers Group (KWT) in Argorejo is a forum for women to improve the village economy through goat and muscovy duck farming activities. This group faces three priority problems: the lack of alternative electricity sources for barn lighting, the lack of an independent livestock feed management system, and the lack of processing of livestock waste into compost. The purpose of this community service activity is to increase production and the implementation of management and alternative energy in KWT Dawis41. This activity is carried out through five systematic methods that include program socialization, training, technology application, mentoring and evaluation, and program sustainability. The Appropriate Technology (TTG) implemented is one solar panel unit, one feed chopper unit, and one compost mixer unit. This program successfully resolved the problems faced by partners in the areas of production and management. The implementation of TTG has succeeded in increasing the level of community empowerment with a breakdown of 100% for the Solar Panel TTG, 58% for the Animal Feed Chopper TTG, and 45% for the Compost Mixer TTG. The training also yielded positive results, with 61% of the 23 participants responding with a good understanding of TTG use and waste management. The community partnership program successfully resolved partner issues through effective TTG implementation, improving business efficiency and group empowerment.

Abstract

This research focuses on manufacturing composite wings using the vacuum bag process. The vacuum bag method is used because it can reduce manufacturing time and improve the quality of the final product. This study aims to determine the impact of the vacuum bag method on the geometry between the design stages and the final results of the UAV wing. Differences in design geometry and final results are calculated by measurement. The effects of variations in thickness and loading were estimated by modeling simulations with Fusion360 Software. The geometry of the design stage and the final result did not have a significant change, with a difference of 10% in thickness, 2.45% in wing length, and 0.80% in wing width. For deformation, it can be concluded that the increase in thickness and loading is directly proportional to the magnitude of the deformation that occurs. The greater the value of thickness and loading, the greater the deformation that occurs.

Abstract

Currently, the aviation industry is experiencing rapid growth, not only in manned aircraft but also in the development of Unmanned Aerial Vehicles (UAVs). One of the crucial components in UAVs is the propeller. Common manufacturing methods for propellers include forming, hand lay-up, and vacuum bagging. Alternative methods with promising potential include silicone molding and three-dimensional (3D) printing. This study aims to determine the most suitable manufacturing method for producing a propeller with a Clark Y airfoil type. The research was conducted using simulation, geometric analysis, and visual analysis. The silicone molding method can serve as an alternative to injection molding, as the dimensional difference between the CAD design and the final product is relatively minor, with the maximum shrinkage recorded at -8.77%. Meanwhile, the 3D printing method is more appropriate when the airfoil thickness is greater.
