Abstract

Transformasi digital dan perkembangan Generative Artificial Intelligence (Generative AI) telah membawa perubahan signifikan dalam praktik rekrutmen kerja, khususnya dalam penyusunan dokumen karier profesional seperti Curriculum Vitae (CV) dan surat lamaran kerja (cover letter). Mahasiswa vokasi sebagai calon lulusan siap kerja dituntut memiliki kemampuan adaptif terhadap perkembangan teknologi digital serta keterampilan dalam menyusun dokumen karier yang kompetitif dan selaras dengan standar industri. Namun demikian, masih banyak mahasiswa yang mengalami kesulitan dalam menghasilkan dokumen yang efektif, terstruktur, dan kompatibel dengan sistem Applicant Tracking System (ATS). Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kesiapan karier mahasiswa vokasi di Kota Madiun melalui model pelatihan hybrid yang mengintegrasikan pemanfaatan generative AI. Program ini melibatkan 120 mahasiswa vokasi yang dibagi ke dalam empat kelas pelatihan. Tahapan pelaksanaan meliputi persiapan, pelatihan interaktif hybrid, serta evaluasi melalui pretest dan posttest. Aplikasi Generative AI yang digunakan meliputi chatgpt, canva, text-to-speech, dan duolingo. Hasil evaluasi menunjukkan adanya peningkatan signifikan pada pemahaman peserta, yang tercermin dari kenaikan skor posttest. Selain itu, CV dan cover letter peserta menunjukkan perbaikan pada aspek struktur, kualitas konten, optimasi ATS, dan tampilan visual. Peserta juga memberikan respons positif terhadap relevansi materi dan manfaat praktis pelatihan. Program ini menunjukkan bahwa pelatihan hybrid berbasis generative AI efektif dalam mendukung peningkatan literasi digital dan kesiapan karier mahasiswa vokasi, khususnya dalam menghadapi tuntutan kompetitif industri perkeretaapian.

Abstract

Safety in railway shunting operations requires continuous monitoring of train distance and speed to reduce the risk of operational accidents. In practice, shunting activities are still highly dependent on manual observation and verbal communication, while the performance of vision based safety systems under real operational conditions remains uncertain. In addition, comprehensive performance evaluations of deep learning based object detection models in real shunting environments, particularly under different hardware capabilities and lighting conditions, are still limited. This study aims to evaluate the performance of the YOLOv8 algorithm for real-time distance and speed monitoring during railway shunting operations. The system was tested using a camera-based detection approach under different processor configurations, namely an internal CPU and an RTX GPU, and under morning, daytime, and nighttime lighting conditions. System performance was evaluated based on accuracy, precision, and real-time detection capability across these conditions. The results show that the system achieved an average accuracy of 87.32% when operating on a CPU which increased to 91.30% when using a GPU. Optimal performance was observed under adequate daylight conditions, while reduced lighting led to a decline in performance, particularly on CPU-based processing. These findings indicate that hardware configuration and lighting conditions play a critical role in determining the reliability of YOLOv8-based safety monitoring systems for railway shunting operations.

Abstract

Tourism-based creative economies require distinctive souvenirs that draw on local resources and reflect regional cultural identities. Preliminary observations around the Reog Ponorogo Statue tourism site indicated that some souvenirs were sourced from outside the region, suggesting opportunities to strengthen local production. This community empowerment study aimed to improve the knowledge and skills of members of Karangtaruna Panca Manunggal Anderpati in Carangrejo Village, Ponorogo, through training in resin souvenir production using natural materials. Twenty-two participants took part in a needs assessment, preparation of tools and materials, technical training, guided production, locally inspired design development, and introductory digital marketing activities. The evaluation was structured around Kirkpatrick's four levels—reaction, learning, behaviour, and results—while changes in assessed competence were examined using pretests, posttests, and normalized gain (N-gain). The overall mean assessment score increased from 48.77 to 82.27. Mean scores also increased in resin material knowledge (48 to 83), natural-material selection (52 to 86), moulding and finishing techniques (45 to 81), and digital marketing competence (40 to 78). N-gain values ranged from 0.63 to 0.71, corresponding to moderate-to-high improvement under the adopted classification. Participants produced souvenir prototypes incorporating natural materials and design elements inspired by Ponorogo's cultural tourism. The findings therefore document improved assessment performance and immediate application of practical skills within the participating group. Production continuity and effects on sales or income were not evaluated.
