Abstract

Traction Energy Asia 2020 reported that 3 million kilolitres of WCO were collected in Indonesia in 2019, 1.6 million kilolitres from urban households. WCO poses risks due to common reuse or disposal. Repurposing for MES surfactant is vital. Hence, this study aims to produce an MES surfactant from WCO feedstock using NaHSO3 as a microwave-assisted reactant by observing the influence of variables such as reactant mole ratio, catalyst concentration, sulfonation reaction time, and microwave power. The adsorption method involves vacuum filtration of WCO to remove impurities, mixing with activated carbon, and settling before a second filtration. Transesterification transforms WCO into methyl ester through mixing with methoxide solution with a molar ratio of methanol to WCO of 1:9 and a 1 wet% NaOH catalyst based on WCO, followed by washing and drying. Sulfonation involves reacting methyl ester with NaHSO3 (1:1, 1:2, 1:3, 1:4) and CaO catalyst (1%, 1.5%, 2%, 2.5%). The reaction occurs in a microwave at power variations of 300, 450, 600, and 750 Watts, as well as with variations in time of 20, 30, 40, 50, and 60 minutes. After that, it ends with purifying and neutralizing to produce MES. The optimal conditions for MES production are a 1:2 molar ratio of reactants, 1.5% CaO catalyst concentration, 20 minutes, and 450 W, yielding 48.06%. MES characteristics: pale yellow color, density of 0.859 g/cm3, viscosity of 1.780 cSt, and surface tension of 32.62 dyne/cm. FTIR analysis confirms sulfonic acid groups at 1195.27 cm−1 and 1169.1 cm−1 wavelengths.

Abstract

The post-COVID-19 pandemic has resulted in learning loss in almost all subjects, including science learning. In addition, there is a decrease in motivation in capturing learning. In contrast, 21st-century education demands literacy skills accompanied by competencies and characters that lead to lifelong learning. Therefore, services in the form of technology that can improve students' skills and interests are needed, one of which is using virtual reality. This technology is believed to be a future asset that can help students construct their cognitive structures. Thus, this study aims to examine the use of virtual reality technology in improving meaningful learning in science learning at school. The method used in this study is a qualitative method with a descriptive approach through a literature review of Google Scholar and Scopus-indexed journals.  The data that has been collected is analyzed by correlating the relationship between the use of virtual reality with meaningful learning in science subjects. After that, it ends by elaborating on the ideas in this article. Based on studies that have been conducted, it is found that virtual reality is a 3D technology that helps visualize science concepts that combine the real and virtual worlds (immersive) so that learning is more interactive. Despite its great potential, this technology should be used as a supporting tool, not a substitute for human interaction in learning. Virtual reality can also create meaningful learning by directly involving students in constructing their cognitive structures related to facts, concepts, procedures, and metacognition. In addition, this technology is also able to integrate science concepts that were previously fragmented to be integrated comprehensively through 3D virtual simulations. This will help create meaningful learning because students can understand science concepts comprehensively by connecting their experiences to real learning materials through immersive technology. Keywords: Immerse Technology; Meaningful Learning; Science Subject; Virtual Reality

Abstract

This study aims to find out and describe the values ​​of Sundanese local wisdom that can be implemented in literacy-based learning in madrasas in the process of strengthening the Pancasila student profile. This study uses a qualitative descriptive method by analyzing the problem and then breaking it down into ideas. the preparation of this paper uses secondary data by reviewing relevant literature from scientific articles. After the data is collected, the analysis is carried out using descriptive and comparative analysis. The profile of Pancasila students is interpreted as a profile of lifelong students with the character of faith and piety to God Almighty, noble character, global diversity, cooperation, independence, critical thinking, and creative reasoning. In this regard, Sundanese local wisdom can be internalized as silih asih, silih asah, silih asuh, silih wawangi, cageur, bageur, bener, pinter and singer. These values ​​are moral values ​​that are firmly held by the Sundanese people and are relevant to strengthening the profile of Pancasila students. In its implementation, these values ​​are designed through the literacy movement by dividing its activities into 3 stages. The first stage is the habituation stage. At this stage, the inculcation of local wisdom values ​​can be divided into each day of the learning process, so in one week of learning, students can form the expected characteristics of the Pancasila student profile. In the second stage, namely the development stage through the literacy corner. The last stage is the learning stage applying learning models that focus on students.

Abstract

Previous reports showed that there has been a continuous increase in the annual production of onion in Indonesia, and it is inversely proportional to the market price. The price drop is often caused by the high water content, which makes it easy to rot. Preservation of onions through a tray dryer is a good preservation method because it is effective and does not require much energy. Therefore, this study aims to determine the effect of variations in time, material thickness, and air velocity on the drying rate of onions. The samples were sliced to a size of 2 - 5 mm, followed by drying for 60 min using a tray dryer with different air rates between 4 - 7 m/s, and the rate of the process was observed every 15 min. The results showed that the drying time reduced the humidity in the chamber. The highest rate of 0.525 g/min was obtained at the peak air rate of 7 m/s. ANOVA results revealed that variations in time, onion thickness, and flow rate have a significant effect on increasing the drying rate of onions. This indicates that the method can be an effective and efficient solution to optimize the drying of the commodity.

Abstract

The transformation of 21st century education demands assessments that not only measure basic cognitive learning outcomes but also encourage deep engagement of higher-order thinking. Computational Thinking (CT), as a systematic and logical thinking approach to problem solving, offers great potential to be integrated in learning assessment design. Thus, this study aims to explore the development of CT-based assessments in promoting deep learning through analyzing relevant scientific literature. The method used is a descriptive qualitative literature review, by analyzing articles from various scientific sources that discuss CT theory, components, and implementation in the context of education and assessment. Data were collected from articles indexed in Google Scholar, ScienceDirect, and other academic sources, then analyzed thematically and comparatively. The results of the discussion show that CT-based assessments, which involve the components of decomposition, abstraction, pattern recognition, algorithms, and generalization, are able to reveal students' thinking processes in depth. This assessment not only measures knowledge, but also encourages reflective, creative, and transdisciplinary skills. In the context of project-based learning, such as the design of an AI-based automatic air purifier system, CT assessments can serve as a tool that encourages students to contextually understand, design, and evaluate solutions. In conclusion, CT-based assessments contribute significantly to deep learning and need to be systematically developed in educational practice. This is in line with the need to form a generation of adaptive, critical, and solutive learners in facing the challenges of a complex and technology-based modern world.
