Abstract

The COVID-19 pandemic, coupled with climate change repercussions, has gravely impacted global economies, notably the MSMEs in Kelurahan Meteseh. These MSMEs, which play key roles in local tourism and cuisine, struggle with energy and capital issues. This community service program addresses these challenges by implementing a green economic ecosystem for these SMEs, leveraging digital platforms, and promoting environmentally friendly business operations. Methodologically, the project encompassed preparation, technology deployment and installation, technology transfer, and mentoring. To address these issues, a community service program introduced Eco-Crowdinvesting green business technology with solar panels to help MSMEs recover sustainably. Solar panels and the Eco-Crowdinvesting platform reduce operational costs, improve finance, and strengthen MSMEs, making energy affordable for them. In line with national digital and green economy strategies, this program gives MSMEs access to solar power and an innovative financing platform, strengthening their economic resilience, promoting sustainable business practices, and increasing environmental awareness.

Abstract

This regional community service program seeks to empower Micro, Small, and Medium Enterprises (MSMEs) in the Semarang sub-districts of Meteseh and Tembalang by integrating clean energy solutions and smart technology. Meteseh faces significant challenges with plastic waste management, while Tembalang struggles with maintaining a stable energy supply for its MSMEs. To address these issues, the project introduced a solar-powered smart plastic waste shredding machine in Meteseh and a solar panel monitoring system in Tembalang. The shredding machine reduced unmanaged plastic waste by approximately 65%, enabling the processing of up to 15 kg of plastic per hour, while promoting recycling and environmental sustainability. In Tembalang, the solar energy system increased the operational hours of MSMEs’ craft production by 6–8 hours per day, resulting in a 100% increase in production capacity and a 30% reduction in operational energy costs. These initiatives have enhanced MSMEs’ productivity, sustainability, and resilience while fostering socio-cultural transformation and green economic awareness within the communities. The program demonstrates the measurable and transformative potential of clean energy and smart technology in regional development, offering a scalable and replicable model for sustainable economic growth across Indonesia and beyond.

Abstract

Flow-Induced Vibration (FIV) in oscillatory flow represents a complex fluid–structure interaction that remains insufficiently explored, particularly for two-degree-of-freedom (2-DoF) systems allowing coupled inline and cross-flow motion. Previous studies have primarily focused on steady flows or limited parameter ranges, leaving a significant knowledge gap in understanding dynamic responses influenced by both reduced velocity ( ) and Keulegan–Carpenter (KC) numbers. This study aims to numerically investigate the vibration characteristics of a 2-DoF circular cylinder subjected to oscillatory flow, emphasizing the coupling mechanism between the two motion directions under varying  and KC values. The research employed a numerical approach based on the Direct Forcing Immersed Boundary (DFIB) method integrated with Navier–Stokes solvers and structural motion equations. Simulations were conducted for KC values of 5–20 and  ranges between 5–35. The temporal integration was performed using the third-order Adams–Bashforth schemes to ensure accuracy and stability. The results reveal that lock-in phenomena occur within specific UR ranges for each KC value, with resonance peaks identified at  = 5 for KC = 5,  = 10 for KC = 10,  = 15 for KC = 15, and  = 20 for KC = 20. Increasing KC values amplify the interaction between flow and structural responses, producing multi-mode vibrations and nonlinear coupling between inline and transverse motions. Furthermore, galloping phenomena were detected at higher UR, indicating a transition from vortex-induced vibration to hydrodynamic instability. These findings contribute to a deeper understanding of FIV dynamics in oscillatory environments, offering insights for optimizing offshore structure design and wave energy harvesting devices.
