Abstract

The challenge in 4.0 era requires teachers as part of the society to have certain qualities such as able to prepare knowledgeable and skillful students in science, technology, engineering, and mathematics (STEM) subjects as STEM based learning is align with 2013 curriculum in Indonesia. At SDN 6 Tebat Karai, teachers' ability to develop STEM-based learning tools is still lacking, so training in making and developing learning tools is needed. This activity is a community service activity aimed at elementary teachers so that they can design, prepare, and produce a set of STEM-based teaching instruments and able to perform those instruments in a classroom. The community service activity was done in SDN 06 (state elementary school) of Tebat Karai Region, Kepahiang on 28-29th of July 2023. This activity was a training program followed by 15 elementary teachers of Tebat Karai. The training method used was technical assistance method in a workshop that consisted of training, guided practice, monitoring, and evaluation processes. The output of this activity was STEM-based lesson plan using project-based learning model that consist of 6 major learning activities which are: (1) introductory by giving essential questions; (2) project planning; (3) scheduling; (4) project progress monitoring; (5) student assessment; (6) learning experience evaluation. From the activities that have been carried out, the results obtained are an increase in teacher understanding of STEM-based learning tools with a difference in N-Gain value of 0.87 in the high category.

Abstract

This research aims to identify students' misconceptions on redox reaction material using the Four Tiers Diagnostics Test. The four tiers/stages are selecting answer, affirmation of the chosen answer, selecting reason of the chosen answer, and the affirmation of the selected reason. The diagnostic was carried out at SMAN (senior high school) 5 Bengkulu. The trial of the diagnostic test was conducted to students of class X MIPA 3 and the misconception diagnostic was conducted to students of X MIPA 2. The results show that the percentage of student misconceptions regarding the redox reaction material was 35% (medium category), while 40% of students understand the concept, and 25% of students do not understand the concept. The highest misconception occurs in the sub-concept of reduction and oxidation reactions (42%), follows by dispropornation and conpropornation reactions, (38%), oxidizing-reducing agents (37%), change in oxidation number from element to compound (24 %).

Abstract

This study aim is to synthesize and characterize metal organic frameworks La-NDC and determine the electronic response to borax (H3BO3) compounds. The method used to synthesize La-NDC MOFs is the solvothermal method with dimethylacetamide (DMA) as solvent. The research was conducted in the learning laboratory of FKIP UNIB and the Basic Science laboratory of FMIPA UNIB from April to June 2022. The synthesis stages of La-NDC MOFs consisted of six stages, namely preparation, mixing, heating and cooling, washing, drying and weighing. Yield results obtained as much as 70.77% and 63.85%. The results showed that La-NDC MOFs have been synthesized with a slightly yellowish white crystalline form. Characterization of La-NDC MOFs was carried out using FTIR, SEM and XRD methods. The results of FTIR characterization showed that Lanthanum metal ions had coordinated with NDC ligands to form a network of MOFs, XRD characterization results showed that La-NDC MOFs had good crystallinity and SEM characterization results showed that the morphology of La-NDC MOFs resembled irregular rocks with diameters ranging from 73 - 581 m. The analytes used for the response test were borax, benzene, toluene and formalin. The electronic response test of La-NDC MOFs was carried out using a UV-Vis spectrophotometer at a wavelength range of 200-800 nm. The results of the electronic response test on the sample of MOFs with borax show that La-NDC MOFs have no potential as sensors because they do not show specific electronic behavior towards borax

Abstract

The goal of this study is to construct a valid and reliable HOTS-based cognitive assessment tool. The HOTS-based assessment instrument was used to measure students' higher order thinking skills on the buffer solution material. The stages of this research were the analysis, design, development, implementation, and evaluation phases of the ADDIE model. The research subjects were students of class XI MIPA 4 at Senior High School 5 Bengkulu City during the 2021–2022 academic year. The research data came from expert validation sheets, needs analysis questionnaires, empirical test analysis, and examination of students' HOTS skills. The 20 multiple-choice questions and 10 essay questions made up the instrumen's features. The following are the outcomes: (1) The expert's assessment of the practicality of the material led to the creation of 26 valid questions, including 18 multiple-choice questions and 8 essays. (2) The empirical validity study produced 23 valid items, including 6 essay questions and 17 multiple-choice questions. (3) The reliability analysis results for both essays and multiple choice questions fell into the very good category, with scores of 0.94 and 0.98. (4) The findings of the examination of students' higher-order thinking skills revealed that 1 student was in the very good category, 5 students were in the good category, 5 students were in the fairly good category, 22 students were in the poor category, and 1 student was in the very poor category.
