Abstract

Automatic Speech Recognition (ASR) for the Indonesian language faces significant challenges due to high Word Error Rate (WER), especially when using pre-trained models without fine-tuning. This study develops an optimized ASR system using a hybrid cloud architecture that integrates the Faster-Whisper large-v3 engine with advanced audio preprocessing techniques. The system adopts a distributed architecture, with Google Colab (Tesla T4, 15GB VRAM) as the GPU server and Ubuntu 22.04 LTS (8 core, 32GB RAM) as the client. Evaluation was conducted on five Indonesian audio samples covering formal news, informal conversations, and long-duration recordings. The system achieved an 80% success rate in processing, with WER ranging from 27.69% (formal news) to 645.16% (informal conversations). Resource utilization was also efficient, with 21.3% GPU usage and 35.4% RAM usage. Processing time remained stable for normal-sized files but experienced timeouts on large files (>50MB). The results indicate that hybrid cloud architecture is feasible for distributed ASR processing in Indonesian, with several areas still open for optimization toward production deployment.

Abstract

Schools are not only institutions for the transfer of knowledge but also environments that play a crucial role in shaping students’ behavior and instilling positive habits, one of which is environmental care. One form of environmental concern that can be cultivated from an early age is the discipline of disposing of waste properly. However, SD Negeri Jambewangi, located in Dusun Pesantren, has not yet fully implemented effective waste sorting practices. Waste disposal is still carried out without distinguishing between organic and inorganic waste, which may have negative impacts on the school environment. To address this issue, community service activities were carried out by KKN students from Universitas Tidar through outreach programs and the distribution of sorted waste bins. The socialization activity applied the Extend Parallel Process Model (EPPM) communication strategy using a Severity Model approach, which emphasized the dangers and consequences of improper waste management practices. During the sessions, students were encouraged to discuss and identify various types of waste, as well as the potential environmental and health impacts associated with them. Direct practice was also provided by encouraging students to actively participate in sorting waste before disposal into the designated bins. The implementation of this program showed a positive impact, as students demonstrated an increased understanding of waste management and began to practice sorting waste more consistently. The provision of separate bins for organic and inorganic waste further facilitated this new habit. It is expected that the discipline of sorting and properly disposing of waste will continue to be applied by students, teachers, and the entire school community. Such continuous practices can foster collective awareness, contribute to maintaining environmental cleanliness, and provide long-term benefits not only for the school but also for the surrounding community.
