Students' difficulties understanding and identifying various forms of microalgae hurt their learning outcomes. As a result, students become increasingly bored with the learning process. This research aims to develop an interactive E-module to improve conceptual understanding and microalgae identification skills. This research uses research and development (R&D) procedures using the ADDIE development model. The subjects of this research were one media expert, material expert, design expert, biology lecturers for needs analysis, nine students for single trials, and eighteen students for small group trials. The methods used to collect data are observation and interviews. The data collection instrument uses a questionnaire. The data analysis technique uses qualitative, quantitative descriptive analysis and the N-gain test. The research results, namely that the interactive E-module obtained very feasible criteria based on the results of expert validation tests with a percentage greater than 80%. Based on the N-Gain test calculation results, the average concept understanding variable is 0.84, while the identification skills variable is 0.70, indicating a gain value greater than 0.7, which means it is very successful. It was concluded that the interactive E-module was practical and effective in improving student's understanding of concepts and identification skills.

Penelitian ini bertujuan menggambarkan pentingnya literasi digital untuk keamanan data privasi dalam transaksi belanja daring di Indonesia. Penelitian dengan pendekatan kualitatif ini menggunakan paradigma critical-constructivism, dan teknik pengumpulan data wawancara terhadap konsumen pembeli, penjual, pengelola marketplace dan pakar IT. Hasilnya menunjukkan tidak ada jaminan keamanan pengelolaan data pribadi. Sementara Indonesia belum memiliki perangkat hukum setingkat Undang-Undang yang digunakan untuk melindungi data pribadi warga negara. Oleh karenanya diperlukan kecerdasan pengguna dalam bertransaksi, meski di marketplace yang terkenal. Literasi digital diperlukan untuk meminimalkan kebocoran data dan kerugian yang diakibatkannya. Dari aspek marketplace upaya meningkatkan keamanan data pelanggan dilakukan dengan terus memperbarui protokol aplikasi. Literasi digital memang tidak cukup melindungi data pribadi, melainkan diperlukan Undang-Undang Perlindungan Data Pribadi. Setiap individu harus memahami resiko pemberian data pribadi pada ranah digital. Analisis data dilakukan menggunakan kerangka teori difusi inovasi, untuk melihat sejauh mana inovasi dikomunikasikan dengan saluran yang tepat dan berkesinambungan kepada sekumpulan individu dari sistem sosial..
