han. Metode yang digunakan berbentuk deskriptif kualitatif dengan melibatkan 26 siswa sebagai subjek kajian. Data dihimpun melalui empat cara, yakni tes, pengamatan, wawancara, dan penelusuran dokumen. Hasil kajian memperlihatkan bahwa pemahaman siswa atas konsep pecahan tergolong masih rendah, dibuktikan oleh angka ketuntasan belajar yang hanya menyentuh 23,07%. Kondisi tersebut dipengaruhi oleh sejumlah hal, di antaranya lemahnya penguasaan dasar pecahan, rendahnya keterlibatan siswa saat belajar, serta metode pengajaran yang belum diterapkan secara maksimal. Mengacu pada hasil tersebut, diperlukan strategi pembelajaran yang lebih interaktif untuk mendorong peningkatan pemahaman siswa terhadap pecahan.
Fraction is a fundamental mathematical topic that frequently appears in everyday situations. This study set out to examine how well fourth-grade students at SD Negeri 010091 Kisaran Baru grasp the concept of fractions. A qualitative descriptive design was employed, with 26 students taking part as participants. Four data-gathering techniques were used: testing, observation, interviews, and document review. Findings revealed that students’ grasp of fraction concepts was still limited, shown by a completion rate of only 23,07%. Several factors contributed to this outcome, among them a weak foundation in basic fraction concepts, low student involvement during lessons, and teaching methods that had not been optimally applied. Based on these findings, more interactive learning strategies are needed to help strengthen students’ conceptual grasp of fractions.

Abstract:Cayenne pepper (Capsicum frutescens L.) is a horticultural commodity with high economic value and continuously increasing market demand. The success of cayenne pepper production is largely determined by vegetative growth…
in the early stages, which is influenced by the availability of nutrients and plant growth regulators. The use of manure as a source of organic matter and natural Plant Growth Regulators (PGRs) is expected to enhance vegetative growth. This study aimed to determine the effect of manure application and natural PGRs on the vegetative growth of cayenne pepper and to identify the treatment that produces the best growth.The research was conducted from December to January 2026 at the land of the Kopbun Suka Tani Sejahtera Business Research Center, Kota Juang District, Bireuen Regency. The study used a factorial Randomized Block Design (RBD) with a 4 × 3 pattern and three replications. The first factor was the dosage of manure consisting of 0 kg (control), 1 kg, 1.5 kg, and 2 kg per plant. The second factor was the type of natural PGR, consisting of shallot extract, rice water, and coconut water. The observed parameters included plant height, number of leaves, leaf width, and number of branches at 15, 30, and 45 days after planting (DAP). Data were analyzed using the F-test and continued with the Honestly Significant Difference (HSD) test at a 5% significance level if the results were significant.The results showed that manure application had no significant effect on all vegetative growth parameters up to 45 DAP. The application of natural PGRs also showed no significant effect at 15, 30, and 45 DAP, as well as on other parameters. There was no significant interaction between manure and natural PGRs on all observed parameters.
Abstract:This study analyzes the implementation of the waiting list policy in the administration of the Hajj pilgrimage at the Office of the Ministry of Religious Affairs of Central Maluku Regency. A descriptive qualitative approach…
ach was used to examine how the policy is translated into public service practices, particularly in a local context where the waiting period has reached approximately 18 years, with about 2,500 prospective pilgrims and an annual quota of 135 people. Data were obtained through interviews, observation, and document review involving officials responsible for Hajj and Umrah services and relevant community informants. The data were analyzed using the interactive model of Miles, Huberman, and Saldana, consisting of data condensation, data display, and conclusion drawing. The findings show that policy implementation is supported by four interrelated factors: bureaucratic structure, resources, communication, and the disposition of implementing officers. A clear organizational structure and standard operating procedures facilitate coordination and accountability. Competent human resources, adequate facilities, and the use of Siskohat strengthen service accuracy and transparency. Multi-channel communication helps reduce misunderstanding, while professional and empathetic officer attitudes build public trust. The novelty of this study lies in its local-level analysis of Hajj waiting list implementation in an archipelagic regency. The study implies that transparent, responsive, and humanistic public services are essential for maintaining fairness and legitimacy in long-term Hajj queue management.

secara mendalam bagaimana emosi dan belajar sosial memengaruhi proses pembelajaran di sekolah dasar melalui perspektif neuropedagogik dan brain‑based learning. A mixed methods approach was used by combining quantitative analysis (meta-analysis of 173 respondents and 47 indicators of NP, EC, OB, MS, BS) and descriptive qualitative analysis using thematic analysis techniques on semi-structured interviews with five elementary school teachers. The meta-analysis results showed a very strong average effect of the latent construct relationship (t(128) = 12.92; p < 0.001; r ≈ 1.00) with almost zero heterogeneity (Qₑ(128) = 1.67; τ² = 0; I² = 0%), and no significant moderating effects were found for all indicators; the partial meta-regression coefficients for all items were very close to zero and the R² value was 0.000. Qualitatively, three main themes emerged: (1) positive emotions as the foundation of learning readiness, (2) social interaction as a reinforcement of meaning formation, and (3) contextual learning that integrates cognitive, emotional, and social dimensions. Although most teachers have not yet mastered the concepts of neuropedagogy and brain-based learning theoretically, they have intuitively implemented its principles through motivation, praise, humor, group work, collaborative projects, and learning experiences relevant to students' real lives. These findings support the latest theory that places emotions and social interactions as the main drivers of brain function in learning (Immordino Yang, 2016; Tyng et al., 2017; Vygotsky, 1978; Jensen, 2008), and emphasizes the importance of strengthening teachers' competence in understanding and designing brain- and emotion-based learning to support the holistic development of elementary school students.
