Abstract

Transkrip akademik merupakan dokumen yang sangat rahasia di lembaga pendidikan. Oleh karena itu, transkrip akademik harus memenuhi aspek keamanan informasi, yaitu autentikasi, keaslian pesan (integritas data), dan non-repudiasi. Banyak kasus telah dilaporkan terkait pemalsuan dan penyalahgunaan transkrip akademik. Hal ini disebabkan karena tidak adanya perlindungan terhadap integritas dan autentikasi transkrip akademik. Prosedur validasi diperlukan untuk menjamin integritas dan keaslian transkrip akademik. Untuk memberikan perlindungan terhadap integritas dan otentikasi, prosedur tanda tangan digital diperlukan pada transkrip akademik. Tanda tangan digital adalah skema yang terdiri dari dua komponen, yaitu penandatanganan dan verifikasi. Skema ini digunakan untuk menjamin integritas informasi dalam dokumen digital. Penelitian ini mengusulkan prosedur validasi transkrip akademik yang sangat otentik berdasarkan tanda tangan digital menggunakan algoritma Rivest Shamir Adleman (RSA) dan BLAKE3. Skema yang diusulkan memanfaatkan kombinasi algoritma RSA dan fungsi hash BLAKE3 dalam implementasi algoritma tanda tangan digital. Hasil eksperimen menunjukkan bahwa sistem dapat menjamin validitas dokumen transkrip digital dalam format PDF. Kecepatan proses penandatanganan rata-rata pada server localhost A adalah 55,0511 milidetik dan kecepatan verifikasi adalah 19,2658 milidetik. Pada server localhost B, kecepatan rata-rata proses penandatanganan adalah 41,8563 milidetik dan kecepatan verifikasi adalah 11,9715 milidetik.

Abstract

This paper proposes a smart hydroponic system that operates automatically using a fuzzy logic algorithm, integrating IoT functionalities to support smart agriculture. The system allows for remote monitoring and control via the internet, providing real-time data on water levels, pH levels, temperature, and nutrient solution temperature. Precise dosing and temperature control are critical for optimal plant growth, and the system schedules temperature measurements to ensure stability. Unstable temperature can affect pH levels, thereby impacting nutrient absorption. The proposed system employs sensors to continuously monitor the electrical conductivity (EC) and pH levels of the nutrient solution. Fuzzy control is utilized to regulate the nutrient solution pump, automatically adjusting EC and pH levels to promote optimal plant growth. This approach reduces the time burden on producers and provides more precise control over the nutrient solution, resulting in improved growth outcomes. The main contributions of this work are as follows: the development and implementation of an AI-based system integrating a controller, IoT environment, fuzzy logic algorithm, and NFT (nutrient film technology) hydroponics; the creation of a user-friendly interface for farmers through the Smart-Hydroponic application, enabling hybrid monitoring and control of hydroponic farms; the establishment of an IoT-based cloud environment for sensor data monitoring; the implementation of a smart hydroponic system for nutrient sensing, monitoring, and control; and a comparative analysis between smart and conventional hydroponics based on morphological results.

Abstract

Motor vehicle tax payments represent a substantial portion of regional income. However, recurrent delays in motorbike tax payments, notably in the Kandang Limun sub-district of Bengkulu City, pose a significant threat to regional development. This research aims to address these delays by predicting and implementing effective strategies. Using the RapidMiner application and the Artificial Neural Network (ANN) method, a delay rate of 36.14% was predicted. The study incorporates interviews to propose several strategies, including enhancing websites, improving offline and online services, implementing Drivethru services, and using SMS Blast notifications to combat delays. To evaluate the feasibility of these strategies, the research employs the Strategy Alignment Maturity Model (SAMM). The assessment at BPKD reveals a maturity level of 4, signifying an ability to improve and manage processes effectively.The maturity assessment suggests that the proposed strategies for overcoming delays are well-aligned with BPKD's capabilities. They have demonstrated a robust alignment between IT and business strategies, leveraging IT to enhance performance, and conducting thorough business and IT evaluations.In addition to the maturity assessment, the research offers suggestions and evaluation strategies. These encompass the adoption of biometrics for authentication, implementation of chatbots, Samsat self-service kiosks, real-time vehicle monitoring, and the introduction of automatic tax programs.
