Abstract

Improving teacher competency is a key factor in improving the quality of education. One of the latest innovations in teacher professional development in Indonesia is the Merdeka Mengajar Platform (PMM), a digital-based platform designed to provide flexible access to independent training. This study aims to evaluate the effectiveness of PMM in improving teachers' pedagogical and professional competencies, especially in the context of educational transformation in the digital era. The method used is a literature study, by collecting and analyzing relevant literature from reputable academic sources. The results of the study indicate that PMM significantly improves teacher competency through interactive modules, online learning communities, and digital resources designed for learning personalization. Teachers who participate in training through PMM show better ability in implementing innovative learning strategies compared to those who do not use this platform or participate in traditional training. However, the effectiveness of PMM can be influenced by teachers' technological readiness and digital literacy, especially in areas with limited infrastructure. This study highlights the importance of supporting technology-based education policies to ensure that the benefits of PMM can be felt inclusively and sustainably. In conclusion, PMM is a promising solution to address the teacher training gap in Indonesia, but requires a strategic approach to improve its access and effectiveness. Further research is needed to evaluate the long-term empirical impact of this platform on teacher professional development and student learning quality.

Abstract

With the advancement of technology and computing capabilities of computers, various applications and algorithms that were previously not applicable to portable devices such as laptops and smartphones can now be applied. Artificial intelligence (AI) is one of the increasingly popular techniques that are now a part of everyday life. AI is an umbrella term that refers to the simulation of human intelligence by machines that use big data to perform various tasks. AI has benefited many aspects of human life, including education. However, AI also has significant negative effects. This study aims to study the influence of artificial intelligence on students' critical thinking skills. This study uses qualitative research and literature analysis. However, the study also identified several negative impacts, including reliance on technology, unassured information quality, social isolation, and ethical and privacy concerns. Therefore, a balanced and strategic approach is needed in integrating AI in education to ensure that its benefits can be maximized, while its negative impact is minimized.

Abstract

This study aims to examine the understanding of students at Madrasah Ibtidaiyah Ihya Ulumiddin Banjarmasin regarding acid-base reactions through experiments using simple materials, namely vinegar and baking soda. The method used is qualitative research with a case study approach, where data is collected through observation, interviews, and documentation during the experiment. This research involves a number of fourth-grade students as research subjects. The results show that most students understand the basic concepts of acid-base reactions, such as color changes and gas bubble formation, although there are still some difficulties in explaining the relationship between reactants scientifically. This study provides an overview of the potential and challenges in teaching basic chemistry concepts at the Madrasah Ibtidaiyah level, and suggests a more interactive learning approach to enhance student understanding.

Abstract

The Garuga floribunda (Garuga floribunda Decne) plant is one of the species known for its various medicinal properties. This research aims to investigate the inhibitory activity of α- glucosidase and α-amylase enzymes and to determine the optimum concentration of the methanol extract of Garuga floribunda leaves as an antidiabetic agent. The leaves extraction is obtained through an extraction process using methanol as the solvent and tested for itsinhibitory activity against the α-glucosidase enzyme using the p-nitrophenyl-α-D- glucopyranoside (p-NPG) substrate and the α-amylase enzyme using the DNS (3,5- dinitrosalicylic acid) substrate. The method is UV-Vis spectrophotometry. The Phytochemical tests of this plant reveal the presence of flavonoids, alkaloids, saponins, tannins, steroids, and terpenoids. The inhibition test results show that the methanol extract of Garuga floribundaleaves exhibited significant inhibitory activity against both enzymes. The highest inhibition percentage against the α-glucosidase enzyme is 91.09%, indicating very high antidiabetic activity. Meanwhile, the inhibition against the α-amylase enzyme is 7.56%, showing no significant antidiabetic activity. The optimum concentration for inhibiting both enzymes is 1000 ppm.

Abstract

This study aims to assess the scientific argumentation skills of eleventh grade students at SMA Negeri 1 Telaga on the topic of electrolyte and nonelectrolyte solutions. The study employs a descriptive qualitative approach. The data collection method utilized a multiple-choice test with five indicators of scientific argumentatio, comprising 25 questions. The sample comprises 132 students from the eleventh grade at SMA Negeri 1 Telaga. The results reveal that students’ scientific argumentation skills on the topic of electrolyte and nonelectrolyte solutions are categorized as fair, with a claim level of 48,4%, data level of 53%, warrant level of 50,6%, backing level of 44,4%, and rebuttal level of 44,3%. It can be concluded that while students’ argumentation skills are aduwuate, many students still struggle to present a complete argumentation using all indicators. The active participation of both students and teachers during lessons is crucial to improving students’ scientific argumentation abilities, particularly in overcoming misconceptions related to electrolyte and nonelectrolyte solutions.

Abstract

Pineapples are often consumed by humans and produce waste from pineapple skin, but the content of pineapple skin has a water content of 81.72%, crude fiber 17.53%, carbohydrates 4.41%, protein and reducing sugar both have the same content of 13.65%. Usually Mexican people make pineapple skin as a fermented probiotic drink or also called tepache. With the fermentation process in this probiotic drink, of course there is the effectiveness of the Lactobacillus casei microbe which has the ability to inhibit pathogenic bacteria that have the potential in making tepache which is utilized from pineapple skin against sugar concentration. Using the Experimental research method is a systematic, careful, and logical study to control a condition. From making pineapple tepache will produce different tastes, colors, textures and aromas. The less sugar concentration, the more sour it tastes and vice versa. the more sugar concentration, the sweeter it tastes. This is because there is a percentage of lactic acid which will lower the low pH value at the sugar concentration in it.

Abstract

Mathematics is one of the main skills taught from elementary school to college, playing a role in developing critical and logical thinking patterns of students. However, many elementary school students have difficulty understanding mathematical concepts, especially spatial figures, due to the lack of supporting learning media. This study aims to explore the effectiveness of using Trimatra (three-dimensional) media in mathematics learning in elementary schools. Trimatra media, such as three-dimensional models of spatial figures, allows students to visualize and understand the characteristics and relationships between spatial figures in a concrete manner. The results of the literature study show that Trimatra media not only increases students' knowledge of mathematical concepts, but also motivates students to be actively involved in learning, increases critical thinking skills, and overall learning outcomes.
