Abstract

Algoritma Vigenere merupakan model algoritma enkripsi yang masih dikembangkan dalam bidang keamanan informasi saat ini. Salah satu aspek yang dianggap penting dalam bidang keamanan informasi adalah kerahasiaan. Masalah pencapaian kerahasiaan pesan atau informasi yang tinggi sangat penting dalam bidang keamanan informasi. Extended Vigenere dikenal sebagai evolusi dari Vigenere yang menerapkan lebih banyak set karakter. Salah satu pengembangan algoritma Vigenere adalah dengan memodifikasi generator kunci yang digunakan. Eksperimen ini bertujuan untuk menguji pengaruh kerahasiaan informasi pada penggunaan generator kunci Blum Blum Shub (BBS) dan nomor Euler yang diterapkan pada Extended Vigenere. Metode pembangkitan kunci BBS dan nomor Euler digunakan secara berurutan. Sebagai metrik pengukuran, perhitungan entropi dari keluaran Extended Vigenere digunakan. Hasil yang diperoleh berupa peningkatan kerahasiaan informasi yang signifikan dengan nilai entropy achievement lebih dari 79% dari entropy optimum.

Abstract

This community service activity aimed to enhance the security and efficiency of halal certification mentoring services at the Aurum First Sunrise community in Surakarta. The main challenge faced by the partner was the risk of sensitive SME data leakage such as ID cards, recipes, and supply chain information, due to the lack of an adequate document security mechanism. The core solution implemented was Technology Implementation in the form of a Cryptographically-based Document Management Information sistem (utilizing the Light Weight PDAC algorithm) integrated with digital access rights management and user Training. Evaluation demonstrated successful implementation, evidenced by an increase in the average satisfaction of SMEs regarding data security to 97.8%, confirming enhanced trust. Furthermore, digitalization successfully improved the efficiency of the mentoring team, reflected by a satisfaction score of 85.0%. In conclusion, this service successfully transformed the partner into a secure, efficient, and credible mentoring institution, significantly supporting SMEs in accessing halal certification.

Abstract

In the era of public information disclosure, digital documents have become strategic assets in supporting transparent, accountable, and participatory governance. Effective management of these documents is essential to ensure that public information services are responsive and accessible. However, document classification tasks carried out by Public Information and Documentation Officers (PPID) still rely heavily on manual processes, which are time-consuming, inefficient, and prone to human error. To address this challenge, this study aims to develop an intelligent classification model for public documents using Artificial Intelligence (AI) and Natural Language Processing (NLP), integrated within the Data Lifecycle Management (DLM) framework. The proposed solution was designed using the Design Science Research (DSR) methodology and implemented through Agile development practices. Evaluation was conducted in a simulated laboratory environment that mirrors real-world PPID operations.The developed model leverages transformer-based architectures, particularly BERT (Bidirectional Encoder Representations from Transformers), and is compared against traditional algorithms such as Naive Bayes and K-Nearest Neighbors (KNN). Experimental results show that the BERT model achieves superior performance, with an accuracy of 89%, precision of 0.88, recall of 0.89, and F1-score of 0.88. These metrics confirm that Transformer-based models are highly effective for classifying public documents into categories of information accessibility: available at all times, periodic, immediate, and exempted from disclosure.This research highlights the potential of AI-powered classification to streamline public information services, reduce workload, and enhance compliance with information disclosure laws. The findings support national development priorities such as RPJMN 2025 by contributing to digital transformation in the public sector. The study also provides a replicable framework for other government agencies aiming to implement adaptive and transparent document classification systems.

Abstract

The implementation of digital technology, particularly in graphic design, is crucial to enhancing students' skills in the digital era. However, many young people, especially those in orphanages, have not optimally utilized technology for learning and skill development. This is due to limited access and guidance in Information and Communication Technology (ICT). Therefore, this Community Service (PKM) activity aims to improve digital literacy among the children at Panti Asuhan Al-Ikhsaniyah through graphic design training using the Canva application on smartphones. The activity was conducted from August 1 to November 4, 2023, with 15 participants, consisting of 11 males and 4 females, all currently in junior high school. The method used in this activity was Participatory Action Research (PAR), which actively involved the stakeholders throughout each phase, including observation, theoretical and practical training, and reflection on the implementation of the material taught. The evaluation instruments used were pre-tests and post-tests, as well as rubrics for assessing design works. The results showed significant improvement, with 80% of participants successfully creating graphic design posters independently, producing 30 design works. Furthermore, 100% of participants were able to understand and use the Canva application. The average score on the design evaluation rubric increased to 16 out of 20, with 73% of participants feeling more confident in designing posters after the training. In conclusion, the application of digital technology in the form of graphic design using Canva significantly improved participants' skills and confidence, while also benefiting their digital skill development and creativity.

Abstract

Penelitian ini mengintegrasikan pendekatan Socio-Technical Systems (STS) dan Design Thinking untuk menciptakan logo produk minuman herbal yang holistik dan sesuai dengan kebutuhan pengguna. Proses desain dimulai dengan tahap Empathize untuk memahami preferensi visual, nilai-nilai konsumen, dan kebutuhan informasi tentang produk alami. Tahap berikutnya melibatkan pengembangan konsep kreatif melalui brainstorming di tahap Ideate, diikuti dengan pembuatan prototipe yang diuji dalam berbagai media pada tahap Prototype. Pengujian logo dilakukan menggunakan System Usability Scale (SUS) untuk mengukur kegunaan dan kepuasan pengguna terhadap logo yang dihasilkan. Hasil penelitian menunjukkan bahwa integrasi STS dan Design Thinking secara efektif menghasilkan logo yang relevan secara estetika, fungsional, dan diterima oleh audiens target. Pendekatan ini dapat digunakan dalam proyek desain lain yang memerlukan keseimbangan antara elemen sosial dan teknis.
