Analysis of Metal Fiber Testing with Pondidaha Coarse Aggregate and Konawe Fine Aggregate Against Flexural Strength (Beams)

Haydir, Haydir, Eva Delpia, Villa, Sakti, Putra, Safitri Maladeni, Eva
Abstract: The territory of Indonesia is a high level of earthquake risk among several earthquake areas around the world. One way to reduce the occurrence of potential damage to building construction is to utilize waste and metal as… s added material from coarse and fine aggregate to the flexural strength of beams that have equivalent flexural strength. The equivalent flexural strength value tends to increase with the addition of metal fibers. This study aims to determine the effect of adding metal fibers to the flexural strength of the beam and the pattern of cracks and collapse mechanisms that occur in the beam when the object is tested. This research is a type of quantitative research with physical laboratory experimental methods. The data collection method used is a preliminary study, The selection of the type of aggregate and metal fiber and secondary data were then carried out laboratory tests for the gradation of fine aggregate and coarse aggregate. The data analysis technique is linear regression analysis in the Ms. program. Excell to determine the effect of metal fibers as additives on the flexural strength of the mixing of coarse and fine aggregates.

Management of Learning Strategies in Elementary Schools During the Covid-19 Pandemic to Maintain Education Quality

Irma Mulyati, Ade, Abin Syamsudin, Tb., Mudrikah, Ahmad, Syaodih, Cahya
Abstract: This research was motivated by the unpredictable Covid-19 Pandemic which forced various parties to carry out social distancing and Work from Home (WFH). This condition has an impact on school closures, students learn from… m home and teachers teach from home. The condition of the Covid-19 pandemic as a new era of Distance Learning. Distance Learning with online/offline/hybrid learning modes as an effort to provide educational services to students. The purpose of this study was to identify and analyze the management of learning strategies in elementary schools during the Covid-19 pandemic to maintain the quality of education. The policy that underlies this research is the Decree of the Minister of Education and Culture Number 719/P/2020 concerning Guidelines for Implementing Curriculum in Education Units in Special Conditions. This research is based on George R. Terry's Theory of Management Functions, according to him “There are 4 management functions, which in the management world are known as POAC; Namely: planning, organizing, actuating and controlling. The approach in this research is a qualitative approach, with a case study type of research method. The research was conducted at Sirnagalih State Elementary School and Al Azhar Syifa Budi Parahyangan Elementary School (ASBP) West Bandung Regency with the research subjects being students. Research results: 1) Schools implement learning strategy management by preparing program plans (materials, strategies, assessments) that are adapted to the Emergency Curriculum and synergize with related parties to carry out learning during the Covid-19 pandemic. 2) Schools have carried out efforts to maintain the quality of education during the Covid-19 pandemic but have not been optimal. This is evidenced by the vast differences between one school and another. On the one hand, there are schools that implement very good distance learning with learning programs and strategies during the Covid-19 pandemic that are well planned by organizing human resources by conducting in-house training, but in other schools distance learning is carried out simply because schools have not establish learning policy guidelines during the Covid-19 pandemic. 3) Implementation of elementary school learning during the Covid-19 pandemic with online/offline/hybrid learning modes. 4) There are several obstacles in primary school learning during the Covid-19 pandemic, including the limitations of studying the Emergency Curriculum with studies on the selection of Core Competencies and Basic Competencies, the fulfillment of facilities and infrastructure, the condition of teachers who when carrying out learning still refers to student books as learning resources. 5) There are solutions to overcome obstacles including schools being required to improve teacher competence to be technology literate, designing adaptive curricula and facilitating adequate infrastructure, as well as Hybrid Learning with visiting teachers (Jarunjung). The conclusion of this study is that the management of learning strategies in elementary schools during the Covid-19 pandemic to maintain the quality of education has been attempted by implementing Distance Learning both online/offline/hybrid learning, but the results have not been optimal.

Abstract: This study aims to examine the application of the High-Low method, Scatterplot, and Least Squares in cost analysis, particularly in separating fixed and variable cost behavior. The research uses a library research approach… ch by collecting and reviewing literature from textbooks, journals, and official publications related to cost estimation and cost behavior modeling. The findings indicate that the High-Low method is simple because it uses only the highest and lowest activity levels, but its accuracy is limited due to reliance on extreme data points. The Scatterplot method provides a visual representation of the relationship between cost and activity, helping identify patterns and potential outliers; however, its results may vary due to subjective judgment in determining the cost line. Meanwhile, the Least Squares method is considered the most accurate because it utilizes all available data to produce the best-fit regression line, although it requires more complex calculations and statistical understanding. Overall, the selection of the most suitable method depends on the objective of the analysis, data availability, and the level of accuracy required
