Abstract

Learning evaluation plays a crucial role in early childhood education because it helps teachers understand child development and the effectiveness of learning activities. This study aims to examine early childhood learning evaluation, encompassing basic concepts, objectives, principles, types, and evaluation methods. The study employed a qualitative descriptive approach through a literature review, reviewing various relevant sources. The study's findings indicate that early childhood learning evaluation needs to be conducted continuously, taking into account both the child's learning process and outcomes. Various techniques, such as observation, portfolios, interviews, and assessment of work, are used to obtain a picture of child development. Appropriately implemented evaluation can serve as a basis for future learning planning and support optimal child development.

Abstract

Biosynthesis of silver nanoparticles (AgNP) is a process of changing Ag+ ions to Ag0. The biosynthesis method in this research is green synthesis using natural ingredients to reduce silver, this synthesis is safer, environmentally friendly and economical. Based on this, this research aims to determine the optimal reaction conditions in the biosynthesis process using ethanol extract from cock leaves. The research method carried out pH optimization with variations of 8, 9, and 10 and then obtained the best pH, where the pH optimization will later be used in the AgNO3 optimization process with variations of 1mM, 2mM, and 4mM. After obtaining the best Ag optimization, the next stage was extract optimization using variations of 0.5%, 1% and 2%, the results of which will be seen based on the SPR peak of 400-500 nm which indicates the formation of AgNPs. The results of the research showed that AgNPs from cockang leaf ethanol extract were able to reduce at pH 8, AgNO3 2mM and 4mM, as well as 0.5% extract, and the contact time reaction showed a good formula for AgNP 1, AgNP2, AgNP3 which was indicated by the absorbance intensity at long waves that form AgNPs at the SPR peak of 400-500. Based on the results of SEM characterization, the morphology at a concentration of 2 mM has a surface that is not very smooth and the size is not very uniform, but at a concentration of 4 mM the surface is smooth and the particles are not uniform. With particle sizes in the range of 50-80 nm.
