Abstract

Keamanan jaringan nirkabel tetap menjadi isu krusial seiring meningkatnya ancaman serangan Man-in-the-Middle (MitM), khususnya melalui metode Evil Twin. Serangan ini bekerja dengan menduplikasi Service Set Identifier (SSID) yang sah untuk mengelabui pengguna agar terhubung ke titik akses palsu. Penelitian ini bertujuan untuk mengidentifikasi kerentanan infrastruktur jaringan nirkabel terhadap penetrasi Evil Twin dengan mengimplementasikan metode network scanning. Metodologi penelitian mencakup tahap pemindaian paket data (ping sweep dan port scanning) untuk mendeteksi anomali pada alamat MAC dan kekuatan sinyal (Signal Strength). Hasil penelitian menunjukkan bahwa penggunaan alat pemindaian jaringan secara proaktif mampu mendeteksi keberadaan titik akses asing yang mencoba melakukan intersepsi data. Temuan ini memberikan kontribusi pada pengembangan protokol keamanan nirkabel yang lebih tangguh dan memberikan rekomendasi teknis bagi administrator jaringan dalam memitigasi risiko pencurian informasi sensitif.

Abstract

The appropriate use of learning media is essential as a tool to help students explore and enhance their understanding. In line with the advancement of time and technology, the learning process and access to information are no longer limited to what is provided by the teacher but can also be obtained from various sources, including social media. Therefore, this study aims to develop Instagram-based learning media as a self-learning resource for students. This media covers the topic “Chemistry in Our Environment”. The type of research used in this study is design and development based on the Richey and Klein model, which includes three stages: planning, production, and evaluation. This study resulted in the development of Instagram-based learning media on the subject Chemistry in Our Environment, which has been tested for its validity. The media contains learning outcomes, learning objectives, meaningful understanding, guiding questions, and learning materials presented on the Instagram account @belmiaclass. The validity test results indicate that this Instagram-based learning media is highly valid, with a score of 93% for content aspects and 100% for media aspects. Therefore, the media can proceed to the next stages, namely practicality testing and effectiveness testing.

Abstract

This study was motivated by difficulties in learning complex and abstract concepts in atomic model development, while commonly used learning videos still provide limited representation, reducing students’ ability to connect concepts with real phenomena. This study aims to develop a multilevel representation-based learning video on atomic model development and to examine its validity, practicality, and effectiveness using a research and development approach involving planning, production, and evaluation stages. The subjects in this study included 2 media experts, 2 material experts, 1 chemistry teacher, and 60 tenth-grade students from classes X-5 and X-6 at SMAN 14 Samarinda. Product validity was assessed by experts, practicality was measured through teacher and student questionnaires and activity observations, and effectiveness was analyzed by comparing pretest and posttest results quantitatively. The results show very high validity, with material expert validation reaching 100% and an average media expert score of 99.25%. Teacher practicality was categorized as very practical, with questionnaire and observation scores of 96.67% and 98.33%, while student practicality scores reached 82% and 81.7%, categorized as practical. The effectiveness of the media was demonstrated by an N-gain value of 0.56 (moderate) and an effect size of 4.94 (very strong), supported by positive student responses with ease of understanding scoring of 82.17% and learning interest of 86.33% (excellent category), while learning activity (79.66%) and media practicality and features (79.83%) fell into the good category. These findings confirm that multilevel representation-based learning videos effectively enhance students’ understanding of atomic model development.

Abstract

Science process skills (SPS) are essential competencies in chemistry learning that support development of scientific thinking and evidence-based problem solving. This study aimed to analyze differences in students' SPS based on gender in chemistry learning at a public senior high schools in Samarinda. The study used a retrospective comparative quantitative approach. The SPS data were collected by using documentation technique involving 65 SPS of eleventh grade students (31 males and 34 females) who programmed chemistry subject. SPS data were analyzed descriptively and inferentially using the Mann-Whitney U test (α = 0.05). The results showed that there was no significant difference in overall SPS between male and female students (p = 0.333) and in most indicators (p > 0.05), except for the observation indicator (p = 0.004), with female students having a slightly higher descriptive mean. These findings confirm that mastery of SPS is more influenced by the quality of the learning process than by gender factors, thus contributing empirically to the application of inclusive science learning oriented towards scientific activities.

Abstract

Science learning needs to provide students with direct learning experiences by utilizing the surrounding environment as a learning resource. However, based on observations, plant classification learning at SMP Negeri 20 Penajam Paser Utara still relies on textbooks as the main learning resource, and herbarium-making activities have never been conducted. This activity aimed to empower students through herbarium-making training as a science learning medium. The activity used a descriptive quantitative approach with a training method consisting of preparation, material delivery, demonstration, guided practice, and evaluation. The participants were 93 students divided into 16 groups. Data were collected through student questionnaires and observer observation sheets using a 1–4 Likert scale and were analyzed using percentage analysis. The questionnaire results showed an average student response of 81.4%, categorized as Very High, while the observation results for practical skills and collaboration were 79.9% and 76.7%, respectively, both categorized as High. These results indicate that herbarium-making training can support student empowerment by developing knowledge, practical skills, and cooperation in science learning.
