Abstract

This study aims to determine the effect of the flipped classroom model on the problem-solving ability of students in the industrial revolution era 4.0. This study is a type of meta-analysis research. Data sources come from 13 national and international journals published in 2021-20224. The inclusion criteria in this study are research derived from journals indexed by Sinta and Scopus, research related to the influence of the flipped classroom model on students' problem-solving abilities, tracing data sources from Researchgate, SciencedDirect, Mendeley, and ERIC, and research has complete data to calculate the value of effect size. Data analysis with the help of Microsof Excel and Jamovi applications. The results of this study concluded that the application of the flipped classroom model had a significant effect on students' problem-solving abilities with an average effect size value of 1.14 and Standard Error of 0.42. This finding has a positive impact on teachers to apply this flipped classroom model in developing students' problem-solving skills.

Abstract

This study aims to determine the management of integrated water resources (IWRM) in cross-border river areas. This type of research is a literature review research. The data sources in the study analyzed several relevant literatures. The keywords for searching for data sources are water resources, off-limits rivers; and river flow. Data analysis techniques in the study are through qualitative analysis using atlas.id application. The results of this study conclude and best practices in the application of IWRM in various geographical and institutional contexts. The results of the review show that IWRM is a crucial approach in overcoming the problem of transboundary water management, but still faces various obstacles such as lack of coordination between countries, conflicts of interest, and climate change. This research highlights the importance of international cooperation, community participation,

Abstract

Concrete is a brittle and fragile construction material so it needs to be increased in strength. This study aims to increase the strength of concrete by adding natural fibers of water hyacinth to the concrete mixture. Hyacinth fibers are cut by 3-5 cm and added with variations of 0%, 0.1%, 0.2%, 0.3%, 0.4% and 0.5% of the volume of concrete. Cylindrical specimens 15 cm in diameter and 30 cm in height were tested for compressive strength and tensile strength at the age of 28 days. The test results showed that the addition of hyacinth fiber up to 0.5% increased the compressive strength of concrete up to 17.6% and tensile strength up to 71.4% compared to normal concrete without fiber. The increase in strength is due to hyacinth fibers being able to withstand micro-cracks in concrete. The more fiber added, the more microcracks are able to be prevented thereby increasing the strength of concrete. In conclusion, the natural fiber of hyacinth effectively increases the strength of concrete both in compressive and tensile capacity.
