Abstract

The role of teachers in education goes beyond simply delivering teaching materials. A teacher must create an exciting and interactive learning atmosphere that captivates students' attention and encourages active participation in learning. Teachers often face challenges in creating engaging and relevant learning materials while integrating the latest technology, which can impede the achievement of learning goals and reduce the effectiveness of the teaching-learning process. A significant issue is the lack of student motivation and involvement, evident from boredom and inattention despite using various learning resources. This study aims to address this issue by developing a Pop-Up Book-based learning media utilizing Augmented Reality (AR) for science subjects in Grade V Elementary School. The research was conducted at SDN Pandanwangi 3 and followed the ADDIE development model—Analysis, Design, Development, Implementation, and Evaluation. The findings indicate that the AR-based Pop-Up Book is effective in enhancing the quality of learning. Implementing this media at SDN Pandanwangi 3 successfully motivated students, improved their understanding of the subject matter, and demonstrated high practicality according to questionnaires and learning outcomes. The final evaluation confirms that this media is valid, practical, and effective in meeting learning objectives. It is recommended that AR-based learning media, such as Pop-Up Books, be extended to other subjects and educational levels. Further research is suggested to explore the effectiveness of such media across different contexts and disciplines, ensuring broader applicability and impact in academic settings.

Abstract

The science and technology model is learning to teach science and technology in the context of experience and everyday life, focusing on societal issues, whether local, regional, national, or global, with science and technology components. Meanwhile, the scientific approach is an approach to learning science process skills. It uses a scientific approach where students are directed and guided in observing, asking, trying, reasoning, and building networks to disseminate the learning results obtained. Learning outcomes are a path to mastering knowledge or skills in a subject, usually indicated by test scores or numbers given by the teacher. Learning outcomes are obtained from learning to master knowledge, usually developed and shown by numbers. This research aims to determine whether implementing a science and technology learning model based on a scientific approach affects the science learning outcomes of grade IV students at SDN Pemongkong. Researchers are implementing technology in science learning at SDN 1 Pemongkong. Still, many obstacles exist, such as internet signals and technological stupors; only some have a laptop or cellphone. Therefore, the idea that emerged in this research was the use of technology that can be accessed by all students, namely the community science technology model based on a scientific approach, which is expected to improve student learning outcomes. The method used in this research is experimentation. This type of experimental research uses Quasi-Experimental Design or quasi-experiments. The experimental plan used in this research is a Nonequivalent Control Group Design. Hypothesis testing is carried out using uji t (independent samples test). Comparison of the average learning outcomes of the experimental class and the control class for the two classes experienced an increase compared to before learning; namely, the average value of the control class at the pretest 54.82 and increased to 73.10 after learning, while the average value of the experimental class is at posttest 58.07 and rose to 74.42 on posttest. The average learning outcomes are similar between the control class and the class experiment. However, the average learning outcomes of the experimental class are still higher than those of the control class. The class that was taught used the community science and technology learning model. Namely, two students got a score of 90 in the control class, and in the conventional class, only one got a 90. By hypothesis testing, face H0 accepted that the scientific approach-based community science and technology learning model influences the learning outcomes of class IV students at SDN 1 Pemongkong. In this case, it can be interpreted that the community science and technology learning model positively impacts student learning outcomes.

Abstract

Limboto Lake is one of the lakes in Indonesia that has been degraded due to sedimentation and waste disposal, which will affect the lake ecosystem and its surroundings. This research aims to analyze the Magnetic Susceptibility in Vertical Sediments in the fish pond area of ​​Limboto Lake. Efforts must be made to trace sediment's contribution, which is controlled by lithogenic and anthropogenic components. Vertical sediment samples from Fish Ponds in Limboto Lake were taken at one point with a depth of 15 meters using an XY-1A Spindle drilling machine. This type of research uses survey techniques and laboratory tests that use rock magnetism methods, especially susceptibility parameter analysis using the Bartington MS2 susceptibility meter instrument at a low frequency of 470 Hz and a high frequency of 4700 Hz to obtain information on the concentration of magnetic minerals. The sediment samples tested did not go through preparation, such as sieving and drying, but the unsifted samples were put into the plastic holder to analyze the susceptibility magnetic parameter. The measurement results show that the low-frequency magnetic susceptibility (XLF) value ranges from 1.11 x 10-8 m3/kg to 9.68 x 10-8 m3/kg. The concentration of magnetic minerals in this sample contains paramagnetic minerals, and based on the XFD % value, which ranges from 0.206% to 4.714% with an average value of 1.170%, the magnetic minerals in the samples tend to be dominated by coarse-grained non-superparamagnetic minerals (>0.03 µm) and tend to occupy stable single-domain (SSD) and multi-domain (MD) domains. Magnetic susceptibility parameters tested using sediment samples without going through a sieving process can be used to determine sediment characteristics in lake areas that tend to be controlled by anthropogenic components.

Abstract

The skin is a protective barrier against environmental disturbances and infections. Staphylococcus aureus is a common bacterium on human skin that can lead to infections. In light of this, the study investigates the effectiveness of natural liquid soaps in controlling Staphylococcus aureus while promoting overall skin health. The primary objective is to showcase the advantages of using natural ingredients in liquid soap formulations compared to synthetic chemicals. To achieve this, the researchers conducted a systematic literature review (SLR), utilizing reputable databases such as PubMed and Mendeley to gather relevant studies focused on natural liquid soaps. They carefully selected articles based on inclusion criteria established through the PICO framework, emphasizing the antibacterial effectiveness of these natural products against Staphylococcus aureus. The review encompassed ten high-quality studies, revealing that formulations containing natural extracts such as breadfruit leaf, cardamom, aloe vera, and honey exhibited significant antibacterial activity against Staphylococcus aureus. These natural ingredients offered effective bacterial control and provided additional benefits, including skin moisturization and reduced irritation, making them preferable to synthetic alternatives. This study introduces a novel perspective by comprehensively reviewing various natural ingredients used in liquid soaps and their comparative effectiveness against Staphylococcus aureus. It underscores the potential of plant extracts and essential oils as safer and more effective alternatives to traditional chemical antibacterial agents in skin cleansers. In conclusion, natural liquid soaps effectively reduce Staphylococcus aureus on the skin while maintaining skin health. Incorporating natural ingredients ensures antibacterial protection without the adverse effects commonly associated with chemical-based soaps, such as dryness or irritation, thereby advocating a shift towards more natural skincare options.
