Abstract

The COVID-19 pandemic is a new situation that brings challenges to all sectors, including education. One of the impacts is that there is an adjustment in the implementation of learning, including practicums, which are usually held offline, turning into online learning. In this study, an analysis of the implementation of biochemistry practicum was carried out for two semesters during the Covid-19 pandemic. This study uses a descriptive case study design. Research data obtained from document analysis and questionnaires. There are five classes used as samples of this study. Questionnaires were given to 116 students. The results showed that the implementation of the biochemistry practicum had been carried out well. This is marked by positive responses from students through questionnaires. Even so, there are significant differences in student achievement compared to conditions after the pandemic. This shows that practicum activities, especially those related to laboratory skills, cannot be facilitated with online learning

Abstract

3D printing transforms abstract contexts into more concrete ones and effectively enhances creativity. The purpose of this study is to explore the benefits and challenges teachers face in using 3D printing. The research method used in this study involved a narrative review of various literatures related to the use of 3D printing by science teachers. The results of this study show that there are benefits in using 3D printing as well as barriers experienced by science teachers. The benefits obtained by teachers are not only limited to themselves but also colleagues due to collaboration and of course for students. Teachers' pedagogical skills in designing lessons and using technology also experienced positive changes. Meanwhile, the obstacles in using 3D printing are also felt by teachers such as limited teacher skills, availability of tools and the use of tools that are relatively time-consuming.

Abstract

The increasing adoption of electric vehicles and large-scale energy storage systems has intensified demand for high-performance and sustainable lithium-ion battery separators. This review summarizes recent progress in biopolymer-based separators as environmentally friendly alternatives to conventional polypropylene/polyethylene membranes. Fourteen research articles published between 2020 and 2026 are analyzed, focusing on biopolymers such as bacterial cellulose, chitosan, lignin, alginate, silk fibroin, and poly(L-lactic acid). The discussion covers material classification, membrane fabrication techniques, and modification strategies, including composite formation and crosslinking. Overall, the reviewed studies indicate that biopolymer-based separators generally exhibit improved electrolyte wettability, enhanced ionic conductivity, and adequate thermal stability, leading to competitive electrochemical performance and good cycling stability. In addition to performance benefits, the use of biomass-derived materials and water-based fabrication processes offers sustainability and potential biodegradability advantages. This review highlights current research trends and outlines key challenges related to testing standardization and manufacturing scalability for future lithium-ion battery applications.
