The background to this research is based on observations of students at SMP Negeri 6 Lembor, East Nusa Tenggara, where mathematical critical thingking abilities were still low. Data collection techniques include test results, interviews, and documentation. This data collection used critical thingking ability tests and interviews with twenty students from class 7B, even during the semester of the 2021/2022 academic year. Data analysis techniques use data reduction, data presentation, and concluding students' critical thinking skills in solving mathematical problems using the Blended Learning approach. The results showed that students with critical thinking skills in the 'low' category were only able to fulfill one indicator and did not fulfill all of them because they had not been able to understand the meaning of the problem, formulate concepts, write solutions, and draw conclusions properly and correctly. Students with 'medium' critical thinking skills can meet 2 to 3 indicators because they can only choose the right solution strategy but are still wrong and make mistakes in their calculations. In contrast, students with 'high' critical thinking skills meet all ability indicatorsâ€”critical thinking. Because students can choose a solution strategy and give reasons related to the chosen strategy wholly and correctly, it can be concluded that as many as 80% can think critically in the 'low' category, as much as 10% can think critically in the 'medium' category, and 10% can think critically in the 'high' category.

Salah satu media pembelajaran yang wajib dikembangkan oleh calon guru selama praktik mengajar adalah Lembar Kerja Siswa (LKS). Akan tetapi, berdasarkan hasil observasi yang dilakukan pada calon guru magang di sekolah, diketahui bahwa LKS yang dikembangkan masih kurang inovatif dan belum menggunakan teknologi online. Oleh karena itu, tujuan kegiatan pengabdian ini adalah meningkatkan keterampilan pengembangan e-LKS calon guru melalui pelatihan. Tahap-tahap pelatihan yang digunakan antara lain: 1) pelatihan penyusunan LKS sesuai dengan kaidah pembelajaran inovatif, dan 2) pelatihan integrasi LKS menjadi e-LKS. Masing-masing pelatihan terdiri dari 2 sesi yaitu sesi materi dan sesi praktik. Dari kedua sesi dilakukan evaluasi pengetahuan dan keterampilan untuk melihat peningkatan yang terjadi. Berdasarkan hasil pelaksanaan diperoleh: 1) kegiatan pemberian materi pada pelatihan dapat meningkatkan pengetahuan calon guru mengenai LKS cetak dan e-LKS. Hal ini dapat dilihat dari hasil evaluasi pengetahuan secara online yang mencapai rata-rata 87,5, 2) Keterampilan calon guru dalam mengembangkan e-LKS juga meningkat dengan baik. Hal ini dapat dilihat dari bentuk e-LKS calon guru yang melibatkan masalah sehari-hari, metode penemuan, gambar dengan warna-warna atraktif, serta bentuk koding-koding input bervariasi pada Liveworksheet.

Abstrak. Pemikiran awal yang melatarbelakangi pemilik membuat suplemen organik untuk hewan ternak ayam adalah pemilik ingin bisa berternak di lingkungan perumahan tanpa memberikan dampak negatif terhadap lingkungan berupa aroma tidak sedap dari kotoran ayam. Dalam proses pembuatnnya itu ternyata 1 resep bisa untuk 10 liter produk, sedangkan untuk pemakaiannya hanya digunakan 10 ml untuk 1 liter air minum ayam, sehingga muncul keingingan untuk menjual di market place. Sampai saat ini opalfood_farm sudah memiliki 7 produk suplemen organik untuk hewan ternak ayam yaitu air alkali, probiotik, jafer (jahe fermentasi), enzim petelur, enzim pedaging, BREW, dan dragon fermentasi. Tujuan pengabdian masyarakat ini adalah untuk menumbuhkan pemikiran baru di masyarakat bahwasanya berternak ayam tidak harus di desa dengan lahan yang luas untuk menghindari polusi dari bau kotoran ayam, namun dilingkungan perumahan dengan lahan yang terbatas juga bisa dimanfaatkan untuk bertenak ayam. sehingga setiap rumah bisa menghasilkan daging dan telur organik yang jelas lebih bergizi dan tentunya mengurangi pengeluaran bualan untuk belanja dapur. Metode yang digunakan dalam pengabdian masyarakat ini adalah penyuluhan terhadap ibu-ibu PKK RT 01 RW 02 tembalangan kelurahan jatimulyo kecamatan lowokwaru Kota Malang.

This study aims to explore the geometric concepts contained in Papuan cultural heritage and integrate them into mathematics learning. The main focus of this study is on three Papuan cultural heritages, namely the Honai traditional house, the Papuan Crown, and the Tifa. These three cultural artifacts not only have deep cultural value but also contain geometric principles that are relevant to mathematics learning. The method used in this study is qualitative research with an ethnographic approach, which involves direct observation and documentation. The data obtained is then analyzed using GeoGebra software to visualize and analyze the geometric shapes in the cultural heritage. The results of the study show that each Papuan cultural heritage contains geometric principles that can be used as examples in mathematics learning, as well as contributing to the development of ethnomathematics learning. The Honai Traditional House, with its circular base, tubular body, and conical roof, reflects the application of stable and efficient geometry. The Papuan crown, with a semicircular base and decorations that contain the principles of rotation, reflection, and dilation, demonstrates the application of symmetrical and harmonious geometry. The Tifa, which is cylindrical or tubular in shape with geometric elements in the form of circles at the top and decorations in the form of isosceles triangles, equilateral triangles, and kites, also reflects the application of significant geometric principles. This study recommends further development related to the application of GeoGebra in ethnomathematics learning and the development of ethnomathematics-based e-LKPD that highlights the cultural heritage of Papua. Thus, it is hoped that mathematics learning can become more contextual and relevant to local culture, as well as provide a more interactive and meaningful learning experience for students. Keywords: Ethnomathematics, GeoGebra, Geometry, Papuan Cultural Heritage.

This quasi-experimental study (pretest–posttest control group design) investigates the effectiveness of a Video Recording Task (VRT) in enhancing the speaking ability of second-semester students in a Visual Communication Design (DKV) program. Sixty participants were assigned to control and experimental groups and received six weeks of instruction. While the control group followed traditional speaking activities, the experimental group engaged in structured VRT-based tasks. Pre- and post-test data were collected to assess gains in fluency, accuracy, pronunciation, and vocabulary. The pre-test and post-test results of the experimental group (n = 30) show improvements across all speaking subskills, with fluency increasing from 22.1 to 27.4 (gain = +5.3), accuracy from 23.2 to 27.1 (gain = +3.9), and pronunciation from 24.2 to 27.9 (gain = +3.7). Quantitative results demonstrate a notable improvement in the experimental group, with measurable gains across all four speaking components and a higher overall achievement score compared to the control group. Additionally, participants in the VRT group reported increased confidence and greater engagement in speaking tasks. These findings indicate that integrating video-based activities into ESP instruction significantly supports learners’ oral performance and contributes to technology-enhanced learning practices. The study highlights the pedagogical value of VRT, particularly within creative disciplines such as DKV, and suggests promising implications for future ESP course design.

The development of literacy and numeracy competencies is a primary concern in elementary education, particularly in fostering students’ ability to understand, interpret, and apply mathematical concepts in everyday contexts. However, numeracy learning in elementary schools is often presented through conventional approaches that lack contextual and culturally relevant learning resources. Integrating local cultural narratives, such as urban legends, into digital learning media offers an innovative strategy to enhance students’ engagement and numeracy skills. Therefore, this study aimed to develop a Story Jumper-based learning media utilizing urban legend content to improve elementary school students’ numeracy abilities. This research employed a Research and Development (R&D) approach using the ADDIE model, consisting of Analysis, Design, Development, Implementation, and Evaluation stages. The participants involved elementary school students, teachers, and expert validators. Data were collected through validation sheets, observation, questionnaires, and numeracy tests. Quantitative data were analyzed descriptively, while qualitative data were examined through content analysis. The findings revealed that the developed Story Jumper media met the criteria of validity, practicality, and effectiveness. Expert validation indicated that the media was highly feasible for classroom implementation. The practicality assessment demonstrated positive responses from both teachers and students regarding usability, attractiveness, and accessibility. Furthermore, the effectiveness test showed a significant improvement in students’ numeracy performance after using the media. The integration of urban legend narratives provided meaningful contexts that facilitated students’ understanding of numerical concepts and problem-solving processes. In conclusion, the Story Jumper-based urban legend media is a valid, practical, and effective learning resource for enhancing numeracy skills among elementary school students. The media also contributes to preserving local cultural heritage while supporting innovative digital learning practices in primary education.
