Abstract

The electrospinning method is a method of making nanofibers using the influence of an electric field to produce a jet of electrically charged polymer solution. In this experiment, polyvinyl alcohol (PVA) nanofibers and ketapang leaf extract with various viscosities were made using electrospinning equipment with a static collector. Scanning using an electron microscope (SEM) shows that the morphology of the nanofibers formed looks homogeneous, continuous, and without beads (beads free). The SEM results were analyzed using ImageJ software, which was then carried out using Origin software to determine the fiber diameter. Diameter size distribution with fiber diameter size distribution ranging from 2000 to 8000 nm.

Abstract

This preliminary study investigates the critical thinking skills of Grade VII students at SMP Negeri 01 Belitang Jaya on the topic of temperature and heat, focusing on Ennis's critical thinking indicators. It aims to identify students' critical thinking levels based on five indicators and highlight areas needing improvement. The study uses a qualitative descriptive method, involving 154 students from five classes. Data were collected through questionnaires covering five indicators: providing simple explanations, building basic skills, drawing conclusions, providing further explanations, and managing strategies and tactics. The findings show that students excel in providing simple explanations (74.66%, high category). However, they perform moderately in building basic skills (46.79%), drawing conclusions (58.54%), and providing further explanations (41.60%). Managing strategies and tactics scored the lowest (31.20%, low category). These results suggest a need for targeted educational interventions, especially in strategy and tactics management. The study provides a reference for developing interactive teaching materials, such as augmented reality-assisted e-modules, to improve students' engagement and critical thinking skills. It lays the groundwork for innovative teaching strategies to make the learning process more effective and engaging

This research uses a qualitative descriptive research method. Data collection techniques include: observation and interviews. The research subjects or informants were the school principal, class teacher/homeroom teacher and student parents. Collaboration between parents and teachers is very necessary in the formation and improvement of inclusive education. The research results show that: (1) In inclusive education, the role of the principal as the highest decision holder in an institution greatly influences the direction and goals to be achieved by the institution. (2) There are many factors inhibiting the management of inclusive education at SDN Talang Pantai from the beginning of management until now. The role of the teacher/class teacher is very important in learning, namely the teacher always provides motivation when starting the teaching and learning process, the teacher always pays more attention to children with special needs compared to other normal children and the teacher/class teacher always guides children with special needs when carrying out ongoing learning. (3) Efforts made by parents towards children with special needs, namely that parents pay attention to the child, provide appropriate guidance when implementing inclusive education at school. Parents of children with special needs need to be directly involved in making every decision, starting from school placement to the collaboration they carry out with the school.
