Abstract

This study investigates the effect of building shape on seismic performance in earthquake-prone areas such as Padang City. Using the Indonesian seismic standard SNI 1726:2019, three multi-story reinforced concrete buildings were modeled: a square (regular), a rectangular (regular), and an irregular plan. The analysis focused on internal forces, base shear, displacement, and drift ratio to evaluate differences in structural response. Results show that buildings with horizontal irregularities experience higher internal forces and displacements. The bending moments in irregular buildings are 4.84% higher than in rectangular buildings and 10.07% higher than in square buildings. Base shear is 1.53% and 3.04% higher, respectively. The maximum displacement differences reach 0.93 m (X direction) and 0.54 mm (Y direction). The average drift ratio in the X direction is about 0.56% for all models, while square-shaped buildings show smaller Y-direction drift. These findings highlight that plan irregularities significantly influence seismic performance, providing insights for safer structural design in seismic regions.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a strategic role in the economic growth of Padang City, particularly in the handicraft sector, which represents both cultural identity and a vital source of local economic activity. However, technological limitations and low production efficiency remain major obstacles to improving the competitiveness of local crafts in the global market. This Community Service Program (PkM) aims to integrate 3D printing technology with conventional production methods as an effort to enhance product quality, efficiency, and design innovation. The implementation method includes identifying the potential and challenges faced by artisans, conducting training on the use of 3D printing, and providing mentoring in the design and production processes. This approach combines the artistic touch and craftsmanship of conventional manual techniques with the precision and speed of digital technology. The results show an improvement in artisans’ ability to utilize digital technology for prototyping and developing new designs that are more responsive to market trends. Furthermore, the training and equipment facilitation support continuous knowledge transfer, strengthening the innovation capacity and independence of MSMEs. The combination of traditional skills and modern technology not only produces products with high aesthetic value but also opens opportunities for market expansion and increased economic value. Therefore, the application of 3D printing has proven to be an effective innovative solution for enhancing the competitiveness and sustainability of the local handicraft sector in the era of the digital creative industry.
