Abstract

Penelitian ini bertujuan untuk meningkatkan keterampilan sosial peserta didik kelas IV SDN 5 Palangka melalui penerapan model Problem Based Learning. Penelitian ini dilaksanakan menggunakan penelitian Tindakan Kelas model Kurt Lewin yang dilaksanakan dalam dua siklus, masing-masing terdiri dari tiga pertemuan. Subjek penelitian adalah 19 peserta didik kelas IV SDN 5 Palangka Tahun Ajaran 2024/2025. Data dikumpulkan melalui lembar observasi keterampilan sosial yang memiliki 3 aspek 14 indikator, dinilai oleh dua observer. Teknik analisis  data menggunakan Teknik statistik deskriptif. Hasil penelitian menunjukkan pada pra siklus terdapat (15,8%) peserta didik berkategori sangat kurang, (42,1%) kurang, (15,8%) cukup, dan (26,3%) baik. Setelah tindakan siklus I, kategori sangat kurang menjadi (0%), kurang (10,5%), cukup menjadi (63,2%), dan baik (26,3%). Pada siklus II seluruh peserta didik berada pada kategori cukup (31,6%) dan baik (68,4%). Dengan demikian, PBL terbukti efektif meningkatkan keterampilan sosial peserta didik.This study aims to improve the social skills of fourth-grade students of SDN 5 Palangka through the application of the Problem-Based Learning model. This study was conducted using the Kurt Lewin Classroom Action Research model, which was carried out in two cycles, each consisting of three meetings. The subjects of the study were 19 fourth-grade students of SDN 5 Palangka in the 2024/2025 Academic Year. Data were collected through social skills observation sheets that had 3 aspects of14 indicators, assessed by two observers. The data analysis technique used descriptive statistical techniques. The results of the study showed that in the pre-cycle, there were (15.8%) students in the very poor category, (42.1%) lacking, (15.8%) sufficient, and (26.3%) good. After the cycle I action, the very poor category became (0%), lacking (10.5%), sufficient became (63.2%), and good (26.3%). In cycle II, all students were in the sufficient (31.6%) and good (68.4%) categories. Thus, PBL has proven to be effective in improving students social skills.
IDENTIFIKASI SENYAWA BIOAKTIF EKSTRAK ETANOL DAUN SENGKUBAK (Pycnarrhena cauliflora) MELALUI UJI FITOKIMIA DAN ANALISIS GC-MS SERTA POTENSINYA SEBAGAI ANTIKANKER KOLOREKTAL SECARA IN SILICO Septaria Yolan Kalalinggi; Yuneta Yuneta; Wahyu Nugroho; Letus Sepsamli

Abstract

Sengkubak (Pycnarrhena cauliflora (Miers) Diels) merupakan tanaman endemik Kalimantan yang dikenal memiliki berbagai aktivitas biologis, termasuk potensi antikanker. Penelitian ini bertujuan untuk mengidentifikasi senyawa bioaktif ekstrak etanol daun sengkubak melalui skrining fitokimia dan analisis GC-MS, serta mengevaluasi potensinya sebagai antikanker kolorektal melalui molecular docking secara in silico terhadap protein CDK2 (PDB ID: 2B54). Hasil skrining fitokimia menunjukkan bahwa ekstrak etanol daun sengkubak mengandung alkaloid, flavonoid, tanin, dan steroid. Berdasarkan analisis GC-MS yang dilaporkan oleh Yuneta et al. (2025), lima senyawa mayor yang teridentifikasi yaitu Phytol, Farnesol isomer a, l-Gala-l-ido-octose, E-11-Hexadecenoic acid ethyl ester, dan Pentadecanoic acid ethyl ester. Hasil molecular docking menunjukkan nilai energi bebas pengikatan kelima senyawa tersebut berturut-turut sebesar −6,7; −5,8; −5,7; −5,3; dan −5,1 kkal/mol terhadap protein CDK2. Senyawa farnesol isomer a menunjukkan energi ikatan paling negatif, mengindikasikan interaksi paling kuat dan stabil. Hasil ini menunjukkan bahwa senyawa bioaktif daun sengkubak berpotensi sebagai kandidat agen antikanker kolorektal.

Abstract

Tujuan: Penelitian ini bertujuan untuk menganalisis penerapan program Tujuh Kebiasaan Anak Indonesia Hebat di SD Negeri 1 Palangka serta mengidentifikasi faktor pendukung dan penghambat pelaksanaannya. Program ini bertujuan membentuk karakter peserta didik melalui pembiasaan positif yang meliputi bangun pagi, beribadah, berolahraga, makan sehat dan bergizi, gemar belajar, bermasyarakat, dan tidur cepat. Metode: Penelitian menggunakan pendekatan kualitatif deskriptif dengan subjek kepala sekolah, guru kelas IV, peserta didik, dan orang tua. Pengumpulan data dilakukan melalui observasi, wawancara, dokumentasi, dan angket, kemudian dianalisis menggunakan model Miles dan Huberman. Hasil penelitian dan Pembahasan: Hasil penelitian menunjukkan bahwa sebagian besar kebiasaan telah diterapkan dengan baik di sekolah, seperti bangun pagi, beribadah, berolahraga, makan sehat, dan bermasyarakat. Namun kebiasaan gemar belajar dan tidur cepat belum optimal karena dipengaruhi oleh lingkungan keluarga. Faktor pendukung meliputi dukungan sekolah, peran guru, sarana prasarana, serta keterlibatan orang tua, sedangkan faktor penghambat antara lain penggunaan smartphone berlebihan, perbedaan pola asuh, dan keterbatasan pemantauan di rumah.

Abstract

This study investigates the effect of combining peer tutoring with a project-based learning (PjBL) model on the academic performance of students enrolled in an Educational Statistics course within an elementary teacher education program. A quasi-experimental design was employed with two intact classes (n = 42) from a state university in Indonesia. The experimental group received peer-assisted PjBL instruction, while the control group experienced conventional PjBL without peer tutors. Both groups followed the same syllabus, instructor, and assessment structure. Data were collected through standardized Midterm (UTS) and Final (UAS) exams validated by subject-matter experts. The findings revealed that students in the experimental group achieved significantly higher academic performance and demonstrated greater improvement from midterm to final exams compared to the control group, with a moderate effect size (Cohen’s d = 0.59). The integration of peer tutoring within project-based activities effectively reduced anxiety, encouraged collaboration, and deepened conceptual understanding of statistical principles. These results confirm that peer-supported, project-based instruction offers a practical and contextually relevant approach to improving statistical learning outcomes among pre-service teachers. The study underscores the importance of active, student-centered pedagogies in preparing future educators to navigate data-rich educational environments. Future research is recommended to examine the long-term retention, scalability, and adaptation of this model across different subjects and institutional settings.

Abstract

Background: The Suggestopedia method is a learning approach that emphasizes providing positive suggestions to students through a comfortable, relaxed, and enjoyable learning environment. This method was developed by incorporating music, voice intonation, and a conducive classroom atmosphere to enhance students' concentration and their ability to absorb learning materials. Through this approach, the Suggestopedia method is believed to help students learn more effectively, particularly in improving their reading comprehension skills. Aim: This study aims to describe the implementation of the Suggestopedia method in instructional materials to improve the reading comprehension skills of fourth-grade elementary school students. The research employed a library research method using a qualitative descriptive approach with content analysis techniques. The data were collected from various relevant literature sources, including books, scientific journals, and previous research findings. The data collection technique involved document analysis of curriculum content standards for Indonesian language learning in elementary schools (SD/MI), theories of the Suggestopedia method, and the focus of Indonesian language learning materials for fourth-grade students. Result and Discussions: The findings revealed that six chapters in the fourth-grade Indonesian language curriculum are relevant for the implementation of the Suggestopedia method. These chapters include: Chapter 1 Fictional Stories and Life Values; Chapter 2 Understanding Nonfiction Texts; Chapter 3 Appreciating Children's Poetry; Chapter 4 Informative Texts (Facts and Opinions); Chapter 5 Simple Explanatory Texts; and Chapter 6 Indonesian Folktales. These six chapters are described according to the three stages of the Suggestopedia learning procedure proposed by Georgi Lozanov, as cited in Tarigan (2011), namely: the pre-session stage, the concert session stage, and the elaboration/active session stage.
