Abstract

Variations in billet temperature often lead to uneven stress and heat distribution on the dies during closed-die hot forging. This review aims to identify the die regions that are most vulnerable to excessive loading and to examine how thermal conditions influence the quality of the forged product. The literature analyzed includes studies that combine finite element simulations with actual forging trials carried out at different heating temperatures. The findings consistently show that the die edges experience the highest stress concentrations, particularly when forging is performed at lower billet temperatures, which increases the likelihood of local plastic deformation. In contrast, temperatures within the optimal range promote smoother metal flow, more complete die filling, and a longer die service life. Overall, this review highlights the crucial role of proper billet temperature control in maintaining dimensional accuracy and ensuring stable forging performance.

Abstract

Bandungrejo Village, located in Ngablak District, Magelang Regency, has various village potentials, including natural resources, horticultural agriculture, and distinctive local arts and culture. However, these potentials have not been optimally utilized due to limited integrated promotional media and the low use of digital technology in information dissemination. This condition has resulted in low tourist visitation and limited economic benefits from the tourism sector for the local community. This article is an output of a Community Service Program (Kuliah Kerja Nyata/KKN) aimed at documenting and describing the implementation of an online booklet development as a promotional medium for Bandungrejo Village’s potential. The activity employed a Participatory Action Research (PAR) approach, with data collected through field observations, interviews with village officials, tourism managers, and community leaders, as well as documentation studies of village profiles and supporting data. The implementation stages included identifying and analyzing village potential, coordinating and planning concepts with community partners, producing narrative and visual content, designing and digitalizing the booklet, and distributing it through digital media using links and QR codes. The results indicate that the online booklet effectively presents village potential in a systematic, informative, and easily accessible manner. The availability of this online booklet is expected to enhance the visibility of Bandungrejo Village, strengthen its image as a nature- and culture-based tourism destination, and serve as a sustainable promotional tool for village authorities and tourism management groups in supporting rural tourism development.
