Abstract

Education plays a central role in community development and the enhancement of human resources. In the rapidly evolving digital era, information and communication technology has significantly transformed the education landscape. Technology has become an integral part of the teaching and learning process in schools, bringing both challenges and significant opportunities. Particularly at the Junior High School (SMP) level, subjects like Mathematics, Natural Sciences (IPA), Physics, and Chemistry play a central role in shaping students' foundational knowledge. However, students often have varying levels of understanding and different learning styles. This poses a challenge for teachers trying to meet the diverse learning needs of their students. The use of the same linear teaching methods for all students is often ineffective in such a context. In this research, we employed a literature review methodology. This approach helps summarize and synthesize existing knowledge on the role of technology in enhancing student motivation in Science, Technology, Engineering, and Mathematics (STEM) education. By analyzing trends, findings, and patterns emerging from related literature, we can establish a strong knowledge base for this research. The adaptive learning approach, leveraging technology, has emerged as an intriguing solution. This approach allows for real-time analysis of student learning data and the adjustment of content, material, or teaching methods to suit individual needs. The research highlights the primary benefits of adaptive learning, such as personalized content adjustment, enhanced student motivation, more efficient monitoring and evaluation, and time savings in achieving better understanding. However, the research also acknowledges several challenges, including uneven technology infrastructure, the need for teacher training, and student data protection. Nevertheless, this research emphasizes the importance of adaptive learning in the context of STEM education at the SMP level in the digital era, while recognizing the need for further research to explore the potential of technology in enhancing the quality of education at this level.

Abstract

Abstract.Network anomaly detection is a situation that occurs in network traffic that causes conditions to become abnormal. This research aims to analyze the performance of various machine learning algorithms in network anomaly detection and compare the performance of single classifier algorithms with ensemble learning. This ensemble learning technique has advantages such as increased accuracy and performance, can reduce the risk of overfitting and underfitting by using different subsets and features of data, and can turn weak learning into strong learning. However, on the other hand, this ensemble learning technique also has disadvantages in its use, namely that this ensemble method may not work well with high variance models, as the ensemble method may not be optimized for anomaly detection and that this method can be computationally expensive and time consuming due to the need to train and store multiple models. Some of the techniques used are deep learning, eager learning, lazy learning, bagging, feature selection, boosting, and stacking. In addition to this, this machine learning algorithm has weaknesses, including if any of the data used is incomplete, it will result in inaccurate completion data, making the programming process quite time-consuming. This research can help develop a more effective and efficient network anomaly detection system. The results of this research show that using ensemble learning and feature selection techniques can improve anomaly detection performance by reducing the processing time of redundant data and classification, as well as increasing precision values.

Abstract

Particularly in the context of the technological industrial revolution, information technology is developing more quickly. We cannot prevent technological development in this life because it will inevitably follow scientific advancements in science. Educational technology has the power to transform traditional teaching methods into innovative ones. Even though the term "educational technology" has a very broad definition, it is frequently assumed to refer only to electronics or other technical tools. For this reason, we will talk more about educational technology in this article, particularly as it relates to its development in the context of science's rapid advancement. as well as society culture and technology Programming breakthroughs have virtually eliminated the need for manual implementation Our work and interests these days often stress our proficiency with computers. Logical thinking is crucial to the development of this revolution in order to comprehend its components, particularly the interconnectedness of computer programming algorithms and mathematics. In order to ascertain the actualization of this programming procedure, the literature analysis method was employed in the composition of this work. The sources for this article's collection included books and a number of earlier publications, the titles of which were created using bibliometric techniques. Thus, it is believed that the development of technological knowledge can proceed without hiccups with the involvement of algorithmic programming so that students can enhance the caliber of the amalgamation of technological information in the industrial revolution.

Abstract

Research has been carried out on the use of wood sawdust as an adsorbent for ikat weaving liquid waste. This research aims to determine the effect of using wood sawdust as an adsorbent on ikat weaving liquid waste. This research was carried out at the IKIP Muhammadiyah Maumere Laboratory and the Maumere Health Service Laboratory. The sample in this study was ikat woven liquid waste which was divided into four treatments, namely Control (K) and the other three were treatments (P1, P2, P3) with the addition of 1,2 and 3 grams of activated charcoal. The method in this research is an experimental method with the research design being True Experimental in the form of Posttest Only Control Group Design. The characteristic tests in this research include a water content test with a value of 0.0833%, and a yield test with a value of 1.9634%. The test parameters used include the degree of acidity (pH), Manganese (Mn) content test and organoleptic test. The research results showed that the pH value before contact with activated charcoal was 9.63 (alkaline pH), and after contact with activated charcoal at a dose of 3.0 grams the pH value became 8.01 (alkaline pH). In testing Mn levels before contact with activated charcoal, the value was 4.60 mg/l and after adding 1.0 grams, 2.0 grams and 3.0 grams of activated charcoal, there was a decrease in Manganese levels respectively, namely from 3 mg/l. , 2.78 mg/l and 1.83 mg/l. Furthermore, for the organoleptic test, there was a change in the color of the ikat woven liquid waste from initially black to clear yellow. Thus, it can be concluded that the addition of activated charcoal from sawdust can have an effect on ikat weaving liquid waste.

Abstract

An introduction to algorithms begins with a basic understanding of the algorithm itself. An algorithm is an organized sequence of steps to solve a problem, taking into account systematic sequence and logical goals. Meanwhile, a programming algorithm is a set of instructions that a computer is asked to execute to solve a problem. Good mastery of programming algorithms is absolutely necessary for people who want to study computer science or mathematics. Therefore, this article aims to help readers who want to learn the importance of programming algorithms through basic concepts. This paper uses a literature review method from various types of existing sources to discuss history, function and properties, algorithm structure, notationincluding natural, pseudocode and flowcharts.
