Abstract

The relatively new and innovative welding technique known as friction stir welding (FSW) has found widespread application in the automotive, railway, and aircraft industries. Due to engineering and financial considerations, welding of dissimilar metals is frequently carried out in these industries. During the friction stir welding process, three tool rotational speeds—910, 1500, and 2280 rpm—were utilized, while the welding speed remained constant at 30 mm/min. Several experimental works, including fractography, tensile tests, and observations of the microstructure, were carried out following welding. Results showed that ultimate tensile strength (UTS) and yield strength (YS) expanded as the tool rotational speed was expanded and the best UTS and YS, typically 228 MPa and 156 MPa at the speed of 2280 rpm. The precipitation of AA6061-T6 in the stir zone (SZ) and the increased degree of mixing were linked to the improved weld strengths.

Abstract

Nggirli Park is one of the tourist attractions in Srimulyo Village that is quite crowded and in demand by the community. During the COVID-19 pandemic, Nggirli Park had to be closed. After the pandemic, this park has not been able to revive. Revitalization is an effort to reconstruct the area so that it can improve the function of the previous area. The revitalization of Nggirli Park is one of the programs to support the revival of the tourism potential of Srimulyo Village and is expected to help accelerate revitalization after COVID-19. The Nggirli Park revitalization program is part of community service from Janabadra University, with activities including cleaning, renewing the facilities, greening, and rehabilitating the gazebo. This community service applies the participatory observation method. To obtain information from community leaders to determine the appropriate Nggirli Park revitalization program for the community, community service program students from Janabadra University conducted interviews with Bintaran Wetan Hamlet Chief and the Nggirli Park Management. The launch of several programs is expected to be able to support the growth of tourism in Srimulyo Village so that it becomes a sustainable tourism village.
