Abstract

The inefficiency of traditional administrative processes highlights the need for innovative digital solutions. This study aims to evaluate and compare the performance of blockchain-based and non-blockchain-based business licensing systems to determine which approach offers better efficiency and security. The blockchain system was developed using Hyperledger Fabric with IPFS for data storage, while the non-blockchain system utilized Node.js with the Express.JS framework and MinIO for storage. Testing involved document upload and retrieval operations based on User ID and Document ID. Results indicate that while the blockchain system offers enhanced data integrity and security, it suffers from significantly slower performance, especially in document upload operations. The non-blockchain system demonstrated faster and more consistent response times, suggesting that in contexts where speed is crucial, a non-blockchain approach may be more suitable, despite the security trade-offs.

Abstract

The digital transformation in vocational education demands institutions to optimize the use of Learning Management Systems (LMS) as effective platforms for hybrid learning. Politeknik Penerbangan Indonesia Curug has adopted LMS, yet its usage remains limited to administrative functions and lacks deeper pedagogical integration. This community service initiative aimed to enhance the digital competencies of teaching staff through intensive LMS training based on the Direct Instruction with Guided Practice method. The program's partner consisted of lecturers from PPI Curug. The training was conducted in stages, including material delivery via Telkom University's e-learning platform, interactive offline workshops, guided hands-on sessions, evaluation through pre- and post-tests, and final feedback. Results showed an average score increase of 7.47 points, with 93.3% of participants achieving post-test scores within the 91–100 range. This effort aligns with Indonesia’s Asta Cita vision, particularly Asta Cita 4, in strengthening human resources, science, and technology towards realizing Indonesia Emas 2045. It also supports the Sustainable Development Goals (SDG) point 4 on Quality Education through the digitalization of learning processes. Consequently, this activity reflects the strong commitment of Telkom University’s academic community in upholding the values of HEI (Harmony, Excellence, Integrity), which derive from the AKHLAK BUMN core values, serving as the foundation of institutional culture and service. Through structured collaboration, this program contributes to building an innovative and sustainable digital education ecosystem.

Abstract

Inventions solving problems through the incorporation of technology and social impacts to facilitate human life can be defined as the Internet of Things (IoT). Security and privacy are challenges in various Internet of Things applications given the rapid growth of IoT devices. Meanwhile, IoT devices still do not have sufficient communication security. Communication systems on IoT devices require cryptographic to maintain the security of their communications. The appropriate algorithm to be implemented on IoT devices should be the smallest and fastest lightweight cryptographic algorithm or commonly called Lightweight Cryptography because IoT devices have limited memory and computing power. In this study, the proposed algorithm to be implemented in Long Range or LoRa-based IoT devices is the Simon-Speck, Simeck, and Skinny encryption algorithm. This study discusses the implementation of the Simon-Speck, Simeck, and Skinny algorithms on Long Range-based IoT devices. The parameters compared are the computation time of the encryption and decryption process and the avalanche effect value. In the encryption and decryption process, the Speck algorithm has the fastest computation time. Meanwhile, the highest avalanche effect value is obtained by the Skinny algorithm, which is 50.34%.

Abstract

Kinerja pembangkit listrik tenaga surya dipengaruhi oleh faktor lingkungan seperti suhu, kelembapan, dan intensitas cahaya, yang dapat menyebabkan fluktuasi daya listrik. Penurunan performa akibat kondisi tersebut dapat menghambat pemanfaatan energi surya secara optimal. Penelitian ini bertujuan untuk merancang sistem monitoring berbasis Internet of Things (IoT) untuk memantau parameter lingkungan dan menganalisis pengaruhnya terhadap kinerja sistem. Sistem dibangun menggunakan mikrokontroler serta sensor suhu, kelembapan, dan intensitas cahaya, dengan data yang divisualisasikan melalui antarmuka web, serta notifikasi peringatan dini melalui Bot Telegram. Hasil penelitian menunjukkan bahwa intensitas cahaya sangat memengaruhi daya keluaran, sementara suhu tinggi cenderung menurunkan efisiensi. Kelembapan menunjukkan pengaruh terhadap daya, namun tidak secara langsung memengaruhi efisiensi panel. Daya maksimum sebesar 2232 W tercapai pada iradiasi 431,4 W/m², suhu 35,81°C, dan kelembapan 26,5%, dengan efisiensi 24,7%. Sedangkan daya minimum sebesar 318 W terjadi saat iradiasi 54,2 W/m², suhu 31,25°C, dan kelembapan 57,7%, dengan efisiensi 28%. Kata kunci— Sistem Monitoring, IoT, Suhu, Kelembapan, Intensitas Cahaya, PLTS
