Abstract

Discipline is one of the fundamental aspects in creating a school culture that is conducive to the learning process. This article examines the role of school principals in cultivating discipline within the school environment. The study employs a qualitative approach through literature review and analysis of educational leadership practices. The findings reveal that the principal of SMKN 2 Pelaihari acts as a role model, motivator, and supervisor in instilling the values of discipline among teachers, staff, and students. The strategies implemented include establishing clear regulations, maintaining consistency in enforcing school rules, providing motivation, and fostering a collaborative culture oriented toward disciplinary values. Furthermore, effective leadership is able to build harmonious communication and create a school environment that supports the internalization of discipline as part of students’ character development. In conclusion, the leadership of the school principal is a key factor in shaping a sustainable culture of discipline, which positively impacts the quality of learning and the overall school climate.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan kemampuan mahasiswa dalam memahami bacaan melalui kegiatan menyimpulkan teks berita. Pendekatan yang digunakan adalah kualitatif deskriptif. Subjek penelitian terdiri atas 30 mahasiswa. Teknik pengumpulan data dilakukan melalui tes membaca berupa teks berita, kemudian mahasiswa diminta untuk menyimpulkan kembali isi bacaan tersebut secara lisan. Data dianalisis dengan cara mengklasifikasikan hasil simpulan mahasiswa berdasarkan kelengkapan isi, ketepatan informasi, dan kejelasan bahasa. Hasil penelitian menunjukkan bahwa kemampuan mahasiswa dalam menyimpulkan teks berita berada pada kategori bervariasi, dengan sebagian mahasiswa mampu menangkap gagasan utama secara tepat, sementara sebagian lainnya masih mengalami kesulitan dalam menyusun simpulan yang utuh dan sistematis. Penelitian ini diharapkan dapat menjadi dasar pengembangan pembelajaran Keterampilan Membaca di perguruan tinggi.

Abstract

Polymorphisms in exon 3 of the leptin gene have been linked to reproductive and production traits in sheep. However, comprehensive in silico studies that combine comparative sequence analysis, phylogenetic relationships, gene expression profiling, and protein–protein interaction (PPI) networks across various sheep breeds remain limited. A total of 21 sheep leptin DNA sequences were extracted from NCBI GenBank. The leptin DNA sequences were aligned using BioEdit to identify single nucleotide polymorphisms (SNPs) and amino acid changes. Phylogenetic relationships among various sheep breeds were analyzed using Clustal Omega version 1.2.4. Leptin gene expression in sheep was analyzed using the Expression Atlas database, and leptin protein interactions with other proteins were evaluated using the STRING platform. The results showed that the leptin gene is highly expressed in the hypothalamus and moderately expressed in reproductive organs, highlighting its important role in regulating energy metabolism and reproductive function. Protein–protein interaction (PPI) analysis using STRING revealed a strong interaction between leptin and its receptor, which activates key signaling pathways, including the JAK2–STAT3, PI3K, and MAPK pathways. Genetic analysis revealed a predominance of missense mutations over silent mutations, with SNPs g.92G>A (Arginine→Glutamine) and g.208G>T (Valine→Leucine) appearing consistently across several breeds. Phylogenetic analysis also revealed substantial genetic diversity among sheep breeds, with clustering patterns reflecting distinct evolutionary origins. These findings demonstrate that integrating comparative genomics with functional bioinformatics analyses provides deeper insight into leptin exon 3 variation and serves as a comprehensive in silico framework for future functional validation and association studies in sheep.
