Abstract

This study aims to comprehensively evaluate the potential pharmacological activities and safety profiles of seven secondary metabolite compounds (Caffeic Acid, Syringic Acid, Quercetin, Luteolin, p-Coumaric Acid, Ferulic Acid, and Epicatechin) identified in the Bajakah plant (Spatholobus littoralis Hassk.). The research approach integrates in silico analysis using the PubChem database, biological activity prediction via PASS Online, oral toxicity assessment through ProTox-II, and pharmacokinetic evaluation using pkCSM, which were subsequently validated through an empirical literature review. The results indicate that these compounds exhibit significant activity probabilities, particularly as antimutagenic, antiseptic, and antioxidant agents. Luteolin demonstrated the highest antimutagenic potential, while Quercetin showed dominant antioxidant activity. Toxicity profiling revealed that Luteolin and Caffeic Acid possess the highest safety levels (Class 5), whereas Quercetin requires special attention (Class 3). These computational findings strongly correlate with empirical evidence demonstrating that Bajakah extract exhibits broad-spectrum antibacterial activity against Staphylococcus aureus, antifungal activity against Candida albicans, as well as high antioxidant and anti-inflammatory capacities. This study provides a strong molecular foundation for the development of Bajakah as a safe and effective phytopharmaceutical candidate.

Abstract

Penelitian ini bertujuan untuk mengetahui tingkat kemampuan self-regulated learning siswa SMP Negeri 1 Kabun dan SMP Negeri 3 Tualang. Penelitian ini merupakan penelitian desktiptif kuantitatif, dengan menggunakan pendekatan Survey. Populasi dalam penelitian ini adalah peseta didik SMPN 1 Kabun dan SMPN 3 Tualang, dengan sample yaitu sebagian siswa di SMPN 1 Kabun dan SMPN 3 Tualang yang diambil secara acak. Teknik pengumpulan data adalah survei dengan instrumen berupa kuesioner/angket. analisis data menggunakan statistik deskriptif dengan membandingkan hasil evaluasi dengan kriteria evaluasi selanjutnya membandingkan apakah kedua sekolah tersebut memiliki perbedaan signifikan. Hasil evaluasi menunjukkan kemampuan self regulated learning matematika siswa SMPN 1 Kabun dan siswa SMPN 3 Tualang berada dalam kategori tidak baik. Oleh karena itu, direkomendasi untuk guru memberikan kegiatan-kegiatan yang bisa membuat peserta didik bebas untuk mencapai tujuan pembelajaran matematika serta mengatur waktunya, guru dapat memberikan panduan/pengarahan pada pembelajaran matematika sesuai kebutuhan peserta didik untuk menguasai strategi penataan diri dalam pembelajaran matematika.

Abstract

Penelitian ini bertujuan meningkatkan kemampuan problem solving mahasiswa dengan menerapkan PBMCCS. Metode penelitian yang akan digunakan adalah Mixed Method dengan strategi eksplanatoris sekuensial dan desain penelitiannya adalah equivalent control group pretest–posttest design. Populasi penelitian adalah mahasiswa program studi pendidikan matematika Universitas Islam Riau. Sampel penelitian diambil dengan teknik total sampling. Instrumen penelitian adalah lembar RPP berbasis PBMCCS dan Lembar Kerja Mahasiswa (LKM) terintegrasi kemampuan pemecahan masalah matematis (KPMM). Instrumen pengumpulan data kuantitatif melalui instrumen tes KPMM, dan instrumen wawancara untuk data kualitatif. Teknik analisis data dilakukan secara kuantitatif dan kualitatif. Analisis data dilakukan untuk data kuantitatif dilakukan analisis statistik inferensial dengan pengolahan menggunakan bantuan Microsoft Excel dan SPSS versi 20, sedangkan data kualitatif dianalisis menggunakan analisis deskriptif kualitatif dengan melakukan triangulasi data. Hasil penelitian menunjukkan bahwa terdapat perbedaan peningkatan kemampuan pemecahan masalah matematis mahasiswa yang mendapatkan Pembelajaran Berbasis Masalah dengan Cognitive Conflict Strategy secara keseluruhan, dan berdasarkan level curiosity matematis, terdapat peningkatan kemampuan pemecahan masalah matematis mahasiswa untu level tinggi dan rendah. Dari hasil wawancara diperoleh informasi bahwa sebagian besar mahasiswa memahami apa yang ditanyakan soal, apa langkah yang dilakukan dan memeriksa kembali jawaban yang diberikan, namun sebagian kecil mahasiswa masih kesulitan dalam menentukan langkah atau teorema apa yang dipakai dalam penyelesaian soal yang diberikan. Kesimpulan terdapat peningkatan kemampuan problem solving matematis mahasiswa melalui pembelajaran berbasis masalah dengan cognitive conflict strategy berdasarkan keseluruhan dan level curiosity matematis mahasiswa.

Abstract

Burnout remains a major occupational health concern among nurses, particularly in the post-COVID-19 era, where prolonged job demands continue to compromise psychological well-being and healthcare quality. Although emotional intelligence and social support have been identified as important protective resources, limited evidence has simultaneously examined their roles while accounting for heterogeneity among nurses. This study investigated the relationships between emotional intelligence, social support, and burnout among nurses at Arifin Achmad Regional Hospital, Riau Province. A quantitative cross-sectional correlational design was employed using Structural Equation Modeling–Partial Least Squares (SEM-PLS). Data were collected from 223 nurses selected through purposive sampling using the Wong and Law Emotional Intelligence Scale, the Multidimensional Scale of Perceived Social Support, and the Oldenburg Burnout Inventory. The findings revealed that both emotional intelligence and perceived social support were significant negative predictors of burnout, indicating that nurses with greater emotional competencies and stronger social support experienced lower levels of burnout. To further explore heterogeneity within the sample, Latent Profile Analysis identified two distinct subgroups: Moderate Resource Nurses (66.8%) and High Resource Nurses (33.2%), differentiated by their levels of emotional intelligence, social support, and burnout. These findings are consistent with the Job Demands–Resources theory, emphasizing that personal and social resources buffer the adverse effects of occupational demands on psychological health. The study highlights the value of strengthening emotional intelligence and workplace social support through profile-based intervention strategies to reduce burnout and promote nurses' well-being.

Abstract

Although mathematical conceptual understanding has been widely investigated, limited attention has been given to examining its relationship with demographic and educational factors among vocational high school students, particularly in statistics learning. This study aimed to describe students' mathematical conceptual understanding and analyze the factors associated with it. A quantitative approach with a descriptive-comparative method was employed involving 105 tenth-grade students of SMK Negeri 4 Pekanbaru. The research instruments consisted of a five-item essay test on mathematical conceptual understanding, a 34-item questionnaire, and a student profile form. Data were analyzed using descriptive statistics, the Independent Samples t-test, and One-Way ANOVA. The findings indicated that students' mathematical conceptual understanding was generally in the low category. In addition, the analysis of demographic and educational factors provided a more comprehensive description of the factors associated with students' mathematical conceptual understanding. The findings are expected to serve as a reference for teachers in designing learning strategies that are better aligned with students' characteristics.
