EFFECTIVENESS OF PHYSICS INTERACTIVE LEARNING MEDIA IN IMPROVING LEARNERS’S SCIENCE LITERACY SKILLS: SYSTEMATIC LITERATURE

Dwi Rika Andriyani — 2024-12-13

This study reviews the literature in an effort to determine how well students' science literacy can be raised by utilizing interactive learning resources for physics. Understanding scientific ideas, using science knowledge in daily situations, and analyzing and resolving science-related issues are all components of science literacy. This study has identified and analyzed a variety of interactive learning media, including interactive magazines, interactive kinematics learning applications, interactive electronic learner worksheet based on LiveWorksheets, Higher Order Thingking Skill-based interactive modules, and learning videos based on the 5E learning cycle model. The study's findings show that interactive learning media can be a very useful tool for teaching physics, but its effectiveness depends largely on how well it is implemented, how well the design of the instruction is done, and how well the learning environment supports the student.

The purpose of this study was to determine the conceptual understanding of eleventh-grade students in Science-Three at Senior High School 8 Malang on the topic of temperature and heat. The study used a survey method with a multiple-choice question instrument that had been tested. The data analysis technique used was quantitative descriptive analysis based on the percentage of students' level of understanding. The questions were analyzed by the level of difficulty. The results of the study indicated that students' conceptual understanding score was 45.4%. It can be concluded that eleventh-grade students in Science-Three at Senior High School 8 Malang have a moderate level of understanding of the concepts of temperature and heat. The study revealed that many students had misconceptions about heat capacity and heat equilibrium. This study revealed that many students have misconceptions about heat capacity and heat equilibrium indicating that students do not fully understand this material. The author analyzed students' responses to questions categorized as difficult to determine the extent of their conceptual understanding when answering.

BIOACTIVE GLASS BONE IMPLANT MATERIALS FROM CANE WASTE AND EGG SHELL WASTE

Nafiusokhib — 2024-12-13

Sugarcane bagasse and eggshell waste are common types of waste found in Indonesia. This article introduces an innovation to utilize these two waste materials as bone implant materials, offering a way to increase their economic value. Bone implant materials primarily consist of SiO2 and CaO, both of which can be derived from sugarcane bagasse and eggshell waste. The process of making bone implants begins with the purification of sugarcane bagasse and eggshell waste to produce SiO2 and CaO compounds. Characterizations conducted at each stage of the reaction process in this research include FTIR, XRD, and SEM.The purification of sugarcane bagasse into SiO2 is carried out using a hydrothermal reaction, while the purification of eggshell waste is performed using the calcination method. Once the high-purity raw materials are obtained, the process continues with the production of bioactive glass. Bioactive glass is a biomatrix material used as a bone implant material. Its composition requires SiO2 = 45%, Na2O = 25%, CaO = 25%, and P2O5 = 5% (weight/weight). The sol-gel method is employed to produce the bioactive glass.After the bioactive glass material is produced, it is further characterized to evaluate its structure and properties. Additionally, bioactivity testing is conducted using SBF (Simulated Body Fluid) to ensure its safety when used as a bone implant and its interaction with body tissues.
