Abstract

Critical thinking skills are very necessary in the 21st century, several studies still show that students’ critical thinking skill in Indonesia are still low. This study aims to determine the effect of applying the Jigsaw type Cooperative Learning model assisted by Eco-pop media on the critical thinking skills of fifth-grade elementary school students. The research method used was a pre-experiment with a one group pretest-posttest design. The research subjects consisted of 20 fifth-grade elementary school students, namely 8 male students and 12 female students at an elementary school in Purwakarta. Data collection was carried out through test instruments in the form of pretest and posttest questions, each consisting of 10 essay questions that measured students’ critical thinking skills. Data analysis used parametric inferential statistics with the help of the SPSS application. The normality test results showed that the data were normally distributed, with a pretest significance value of 0.071 > 0.05 and a posttest significance value of 0.155 >0.05. The results of the Paired Sample T-Test showed a significance value of0.000 < 0.05, confirming a significant difference between critical thinking skills before and after treatment. Thus, it can be concluded that the Jigsaw Cooperative Learning model assisted by Eco-pop media has a significant effect in effectively improving the critical thinking skills of fifth-grade elementary school students and is recommended for use in the classroom learning process.

Abstract

: Kemampuan argumentasi logis sangat krusial bagi calon guru, namun miskonsepsi pada materi implikasi matematika masih sering ditemukan. Penelitian kualitatif deskriptif ini bertujuan menganalisis pola penalaran dan struktur argumentasi matematis mahasiswa. Subjek penelitian terdiri atas 30 mahasiswa PGSD, yang datanya dikumpulkan melalui tes tertulis uraian berbasis Higher Order Thinking Skills (HOTS) dan dianalisis menggunakan tahapan pemecahan masalah Polya serta skema Toulmin. Hasil penelitian menunjukkan bahwa sebagian besar Mahasiswa berada pada tingkat kemampuan tinggi dan sukses menyusun argumen deduktif formal dengan jaminan logis yang valid. Sisanya, mahasiswa pada tingkat sedang, masih terjebak pada representasi verbal, mengandalkan intuisi naratif, dan kerap melakukan kesalahan logika affirming the consequent. Disimpulkan bahwa mayoritas mahasiswa telah memiliki tingkat penalaran formal yang tinggi, namun penguatan pemahaman konsep dasar tetap diperlukan.

Abstract

Livestock are routinely exposed to environmental, nutritional, managerial, and infectious stressors that challenge the neuroendocrine and immune systems. Dysregulation of this integrated axis is increasingly recognised as a principal driver of reduced health resilience and productive performance. This systematic literature review characterised the molecular mechanisms underlying neuroendocrine–immune homeostasis in livestock, identified major disruption categories triggered by stressor exposure, and synthesised evidence-based mitigation strategies. Forty-one peer-reviewed articles from 2020–2026 were retrieved from Scopus, Web of Science, and Google Scholar and analysed through data reduction, display, and conclusion drawing. Findings indicate that chronic HPA axis over-activation triggers six inter-related disturbances: periparturient immunosuppression, Th1/Th2 imbalance, reproductive hormone dysregulation, pro-inflammatory cytokine dysregulation, heat-stress-induced endocrine disruption, and negative energy balance collectively heightening susceptibility to mastitis and metritis while suppressing reproductive efficiency and growth. Effective mitigation requires adaptive housing, precision nutrition, and evidence-based welfare practices to sustain livestock productivity in tropical systems.

Abstract

Kegiatan bazar kewirausahaan mahasiswa merupakan media pembelajaran aplikatif yang berperan penting dalam mengembangkan kompetensi bisnis dan kreativitas mahasiswa. Namun, keberhasilan produk yang dihasilkan perlu dievaluasi secara empiris melalui persepsi konsumen. Penelitian ini bertujuan untuk menganalisis persepsi dan tingkat kepuasan pengunjung terhadap produk mahasiswa pada kegiatan bazar kewirausahaan sebagai dasar pengembangan usaha ekonomi kreatif. Penelitian ini menggunakan pendekatan kuantitatif deskriptif dengan metode survei. Data dikumpulkan melalui kuesioner yang disebarkan kepada pengunjung bazar sebagai responden, dengan indikator penilaian meliputi kualitas/rasa produk, harga, kemasan, dan minat beli. Data dianalisis menggunakan statistik deskriptif untuk menggambarkan kecenderungan persepsi dan tingkat kepuasan pengunjung. Hasil penelitian menunjukkan bahwa secara umum pengunjung memberikan persepsi positif terhadap produk mahasiswa, khususnya pada aspek rasa dan kemasan. Namun demikian, aspek harga dan konsistensi kualitas produk masih menunjukkan tingkat kepuasan yang relatif lebih rendah dibandingkan indikator lainnya. Temuan ini mengindikasikan bahwa produk mahasiswa memiliki potensi pasar yang baik, tetapi memerlukan perbaikan pada strategi penetapan harga dan pengendalian mutu agar lebih kompetitif. Penelitian ini diharapkan dapat menjadi data awal dalam pengembangan usaha mahasiswa serta mendukung pencapaian Sustainable Development Goals (SDGs) poin 8 dan 12.
