Abstract

Internet of Things bekerja untuk menyediakan berbagai layanan yang menghubungkan sensor dengan aktuator. Pada masa sekarang, layanan IoT telah banyak digunakan diberbagai bidang. Dengan pertumbuhan eksponensial IoT menyebabkan meningkatnya masalah ancaman keamanan. Untuk memastikan keamanan data tersebut, diperlukan algoritma untuk mengenkripsi data. Algoritma yang paling umum dalam melakukan enkripsi adalah Advanced Encryption Standard (AES). AES adalah salah satu metode yang digunakan untuk mencapai privasi dan kerahasiaan data yang ditransfer melalui berbagai jaringan komputer. Selain AES, terdapat pula SHA256 sebagai algoritma enkripsi. Dalam implementasinya algoritma SHA256 digunakan untuk integritas data dan otentikasi pesan. Metode yang digunakan dalam meneliti perbandingan enkripsi menggunakan algoritma AES (Advanced Encryption Standard) dengan SHA-256 (Secure Hash Algorithm 256-bit), dapat mengadopsi model NDLC (Network Development Life Cycle). Baik AES maupun SHA-256 adalah algoritma yang kuat dan mapan untuk enkripsi data, dan kecepatan keduanya hampir sama dengan perbedaan yang kecil dalam ukuran milisekon.

Abstract

In response to global environmental challenges such as climate change, pollution, and resource depletion, this study aimed to develop and evaluate Education for Sustainable Development (ESD)–oriented science learning materials on the human digestive system to enhance students’ sustainability awareness. Employing a Research and Development (R&D) approach and the ADDIE model, the instructional materials were implemented in a quasi‑experimental design with two eighth‑grade groups at SMP Negeri 2 Tulis during the 2024/2025 odd semester. Sustainability awareness was measured using a 26‑item questionnaire administered as a pretest and posttest. The experimental group, which received the ESD‑oriented intervention, demonstrated a mean pretest score of 70.55 and a posttest score of 92.06 (mean N‑Gain = 0.63). The experimental group showed significantly higher gains in both sustainability awareness—especially in emotional engagement—compared to the control group. These outcomes suggest that integrating ESD into science learning not only improves conceptual understanding but also shaping environmentally responsible and reflective students.
