Schools as educational institutions with information technology services in the form of New Student Admission Systems, e-report systems, and other information technology services require devices supported by good service. Information technology devices must be appropriately managed to conduct business processes according to business goals. With good service management, the business value offered to customers (students) will increase. ITIL V4 contains information technology service management guidelines that contain best practices for information technology service management, including attention to customer experience, value streams, and support for current digital transformation. This research measures information technology equipment services at high schools in Kendal Regency. This research uses indicators adapted to schools with ITIL V4: Key Performance Indicators (KPI) and Critical Success Factors (CSF). The results of this research show that the performance of the hardware needs to be improved, and the value of the maturity model for each service device is still not good.

Usaha mikro kecil menengah (UMKM) perlu memasarkan produk melalui platform digital agar bisa terus berkembang. Salah satu strategi pemasaran yang dapat diterapkan adalah iklan digital. Pelaku UMKM yang ingin cepat meningkatkan pelanggan dan pendapatan dapat beriklan agar membangun kesadaran konsumen adanya usaha dan produk yang dimiliki. Keunggulan menggunakan iklan digital diantaranya peningkatan jangkauan pemasaran, target audiens yang efektif, hasil yang terukur, dan efektivitas biaya. Banyak sarana yang dapat digunakan untuk memasang iklan, Google Ads dan Instagram Ads dapat menjadi media alternatif untuk menerapkan strategi tersebut. Namun demikian, para pelaku UMKM jarang memahami hal itu karena cenderung dianggap kompleks. Oleh karena itu, kegiatan pengabdian kepada masyarakat harus mengajarkan periklanan digital melalui Google Ads dan Instagram Ads kepada pelaku UMKM. Kegiatan dilakukan dengan cara mendampingi para pelaku UMKM di desa Mangunsari, kecamatan Gunungpati, kota Semarang. Hasil kegiatan ini adalah meningkatnya pemahaman dan kemampuan menerapkan iklan digital melalui Google Ads dan Instagram Ads.

SMA PGRI 1 Kendal menghadapi masalah rendahnya pemahaman siswa tentang Internet of Things (IoT), khususnya dalam membangun sistem palang parkir otomatis. Hal ini disebabkan belum adanya mata pelajaran khusus maupun modul pembelajaran IoT di sekolah. Untuk mengatasi hal tersebut, Tim Pengabdian UniversitasIvet melaksanakan pelatihan pembuatan palang parkir otomatis berbasis IoT menggunakan Arduino UNO dalam bentuk prototype. Kegiatan ini bertujuan memberikan simulasi pembelajaran IoT kepada siswa melalui metode ceramah, diskusi, bimbingan, dan praktik langsung. Hasil kegiatan meliputi penyampaian materi, perakitan perangkat sesuai modul, pemrograman Arduino, dan penyerahan produk ke sekolah. Evaluasi menunjukkan peningkatan pemahaman siswa sebesar 80% setelah pelatihan, meskipun terdapat satu kelompok yang gagal membuat prototype. Secara keseluruhan, kegiatan dinilai berhasil berkat dukungan peserta, guru, dan kepala sekolah dalam meningkatkan literasi dan keterampilan siswa di bidang teknologi IoT

Data theft from year to year has increased in the era of big data and society 5.0. One area that requires data security is patient medical data. Medical image data security must be done to protect medical data security from data theft by third parties so that they cannot access the data. The development of Diabetic Retinopathy (DR) is also increasing every year. Determining the severity of DR is done by detecting the Foveal Avascular Zone (FAZ). Encryption is the process of changing a plain image into a cipher image. In this study, we compared the results of image quality and encryption time between the Vigenere Cipher method and a combination of pixel scrambling. The average encryption time of the tested FAZ images is 3.20 seconds. This result proves that the pixel combination method has a faster encryption time than the Vigenere Cipher. Vigenere Cipher encryption time is 4.96 seconds. The existence of the FAZ area with the pixel combination randomization method of the encryption process is also invisible, so third parties will not know about its existence.

The development of Artificial Intelligence (AI) technologies, particularly deep learning has led to the emergence of innovative applications such as deepfake technology, which enables the realistic manipulation of digital images and videos. While this technology offers positive applications in fields such as entertainment and education, it also poses significant risks of misuse, particularly in the dissemination of false information and violations of privacy. Therefore, deepfake detection has become a crucial aspect in preserving the authenticity of digital content. This study aims to analyze the effectiveness of transfer learning methods in detecting deepfake images using VGG16, VGG19, and ResNet50 architectures. The research employs a dataset of deepfake and real images sourced from Kaggle, comprising 10,826 facial images with a resolution of 256 × 256 pixels, evenly balanced between authentic and manipulated content. The data are split in an 80:20 ratio for training and testing purposes. Each model is trained using identical parameter configurations. The performance evaluation of the models was conducted using confusion matrix metrics, including accuracy, precision, recall, and F1-score. The results indicate that the VGG16 model achieved the best performance, with an accuracy of 76%, followed by VGG19 at 72%, and ResNet50 at 58%. VGG16 also outperformed the other models in terms of precision, recall, and F1-score, demonstrating more effective performance in identifying visual manipulation patterns. In contrast, ResNet50 exhibited the lowest performance, which may be attributed to its architectural complexity not being optimally aligned with the characteristics of the dataset. It can be concluded that the transfer learning approach using the VGG16 model is more effective in detecting deepfake images on this dataset. This study also highlights the importance of selecting appropriate architectures and fine-tuning models to the characteristics of the data.
