Abstract

This study aims to determine the structure of morphology and functional groups from activated charcoal for palm oil waste with variations in activation temperature. The process of two stages: the carbonation and activation stage. Carbonation process using a pyrolysis reactor at a carbonation temperature of 200oC -400oC for 6 hours. Then, the sample activated at a temperature of 700 °C, 750oC, 800oC, and 850 °C. Samples were characterization using SEM and FTIR. SEM analysis results show the largest pore size at a temperature of 850 oC with a diameter of 48.3 nm, and the lowest temperature was 700 °C with a capacity of 35.3 nm. Activated charcoal from oil palm shell waste at mesopore size. Next, FTIR analysis results show wave numbers 2165,18 cm-1, 1554 cm-1, 1030,76 cm-1 dan 424,11 cm-1.  The removal of some absorption bands and  the formation of new absorption bands, caused by the activation temperature

Abstract

This study aimed to analyze students' conceptual understanding by using a multi-representation assisted discovery learning model in measurement. This research was conducted in Public High School 1 Kendari. This research is a quasi-experimental study using a one-group pre-post test design. The research method consisted of a conceptual comprehension test using a caliper and a screw micrometer in an essay in the form of a multi-representational test on long measurements. The analysis showed an increase in conceptual understanding between the pre-test and post-test with an average pre-test score of 16.24 (SD = 14) and a post-test of 61.4 (SD = 21). These results indicate an increase in students' understanding of concepts after learning with an average N-gain increase of 0.5 (SD = 0.2) in the medium category. It also obtained the most significant increase in students' understanding of the indicators mentioned parts caliper and micrometer with an N-gain average of 0.6 in the medium category.

Abstract

ICT-based learning resources that are developed still need to be improved, especially in areas where learning facilities are lacking. It causes students difficulty in understanding the learning material. This study aims to develop an e-module on static fluid material based on corporate edition flip pdf software. The type of research used is Research and Development with the ADDIE method. The research object was class XI SMA, with a trial sample of 25 students. The research instrument consisted of validator sheets, teacher and student response questionnaires, and learning achievement test sheets. Data analysis techniques consist of descriptive analysis and hypothesis testing. The results showed that the static fluid physics learning e-module had a validity percentage of 89.95% (very good). The level of practicality of the static fluid physics learning e-module through the results of student responses is 87.42% (very good), and the teacher's response results are 86.25% (very good). The level of effectiveness of the learning e-module through students' learning interest obtains the medium category, and the increase in students' physics learning outcomes obtains the medium category. It indicates that the use of e-modules impacts interest and learning outcomes. The implication of this study is that learning e-modules are available in flip pdf corporate education that can be used by students and teachers as learning resources and can be accessed online online.
