Abstract

Green sintesis Ag nanopartikel menggunakan ekstrak tumbuhan sebagai bioreduktor untuk mereduksi spesies Ag+ menjadi Ag0. Batang tanaman pisang dipilh sebagai bioreduktor karena mengandung senyawa metabolit sekunder. Uji kandungan metabolit sekunder pada batang pisang diketahui mengandung alkaloid, flavonoid, tanin, dan triterpenoid. Karakterisasi Ag nanopartikel menggunakan UV-Vis dan XRD. Hasil analisis menggunakan spektroskopi UV-Vis menunjukkan panjang gelombang maksimum 447 nm yang mengindikasikan terbentuknya Ag nanopartikel. Sedangkan hasil pengukuran XRD diketahui pola difraksi nanopartikel perak ditemukan nilai 2???? yaitu 39,1o;44,3o; 64,5o dan 77,4o.

Abstract

Social studies learning in elementary schools often experiences obstacles in the implementation of practices due to lack of student activity and limited facilities and infrastructure. This study examines strategies that teachers can apply to optimize social studies learning practices by utilizing environmental media around the school. The results of the literature review show that the use of environmental media creatively and in a structured manner can increase student involvement and overcome limited facilities and infrastructure. A contextual approach using local resources has proven effective in creating meaningful learning experiences and improving understanding of social studies concepts in elementary school students

Abstract

Science education (IPA) in elementary schools plays a crucial role in shaping students' conceptual understanding and scientific thinking skills. However, the dominance of conventional teaching methods leads to low student engagement and learning outcomes. This study aims to examine the impact of using instructional modules and interactive learning on improving elementary school students' science learning outcomes. The method used is a Systematic Literature Review (SLR) of relevant articles from various scientific databases published between 2014 and 2024. The findings show that interactive instructional modules in the form of videos, educational games, digital applications, and e-books can enhance student motivation, conceptual understanding, and active participation. Modules with a contextual approach also help students connect science content with their everyday lives. The success of module implementation is highly influenced by the quality of design and teacher competence, especially in applying the Technological Pedagogical Content Knowledge (TPACK) approach and Higher Order Thinking Skills (HOTS) based learning. Challenges include limited infrastructure, teachers' insufficient understanding of differentiation, and gaps between the modules and students' characteristics. Therefore, collaboration between teachers, developers, and policymakers is necessary to support the effective implementation of interactive instructional modules.
