In Silico Evaluation of Chitosan's Antibacterial Potential Against Gram-Positive and Gram-Negative Bacteria
No full textChitosan, a natural biopolymer, has attracted attention for its potential antibacterial properties against a wide range of pathogens. The escalating crisis of antibiotic resistance necessitates the exploration of novel antibacterial agents effective against both Gram-positive and Gram-negative bacteria. This study aimed to predict the antibacterial potential of chitosan against Staphylococcus aureus (a Gram-positive bacterium) and Escherichia coli (a Gram-negative bacterium) using a comprehensive in silico approach. Short chitosan oligomers, specifically trimers, were used to ensure computational feasibility and reliable molecular docking, as full-length polymers are too large for standard docking algorithms. Molecular docking simulations were performed using AutoDock to investigate the interactions between 13 chitosan compounds and the essential bacterial protein DNA gyrase, a key enzyme involved in DNA replication and repair. Binding affinities, interaction patterns (such as hydrogen bonding and hydrophobic contacts), and conformational changes were analyzed. The ligand showing the most favorable docking profile was further evaluated via molecular dynamics simulations using OpenMMDL to assess the stability of the complex over time. The results indicated that the chitosan derivatives, namely aminoethyl chitosan and dimethylaminoethyl chitosan, interact favorably with DNA gyrase in S. aureus and E. coli, respectively, with differential binding energies and interaction modes suggesting potential variations in inhibitory mechanisms between Gram-positive and Gram-negative bacteria. These computational findings support the potential of chitosan as a broad-spectrum antibacterial agent and provide a theoretical framework to guide further in vitro and in vivo validation of chitosan as a novel antibacterial compound
Model-Model Pembelajaran Pendidikan Agama Islam dalam Internalisasi Nilai-Nilai Ekoteologi untuk Pelestarian Lingkungan Hidup
No full textIncreasingly complex environmental problems require educational efforts that address not only technical aspects but also ethical and spiritual dimensions. Islamic Religious Education (IRE) has a strategic role in instilling ecotheological values as an ethical foundation for environmental sustainability. This study aims to examine the role of Islamic Religious Education learning models in the internalization of ecotheological values for environmental conservation. This research employed a qualitative approach using a library research design. Data were collected from scholarly journal articles, academic books, and other relevant literature, which were analyzed using content analysis through data reduction, data display, and conclusion drawing. The findings indicate that active and contextual IRE learning models, such as Project-Based Learning, Problem-Based Learning, and Contextual Teaching and Learning, play a significant role in fostering ecotheological values. These learning models encourage students to connect Islamic teachings with real-life environmental issues, thereby promoting environmental awareness and ecological responsibility. The discussion highlights that the integration of ecotheological values in Islamic Religious Education is more effective when supported by participatory and experience-based learning models, enabling religious values to be understood not only conceptually but also practiced in students’ daily behavior
Pengaruh Game Edukasi Terhadap Hasil Belajar Sejarah Kebudayaan Islam Kelas VIIIA DI MTs Hidayatul Mubtadiin Desa Sidoharjo Kecamatan Jati Agung Kabupaten Lampung
No full textLearning Islamic Cultural History in madrasas still faces challenges in creating an engaging and meaningful learning environment for students. The use of less varied learning methods and media results in low student engagement and suboptimal learning outcomes. The development of educational technology provides opportunities for the use of innovative learning media, one of which is through educational games that integrate learning and game elements interactively. This study used a quantitative approach with a quasi-experimental design. The subjects were class VIII A students of MTs Hidayatul Mubtadi'in, Sidoharjo Village, Jati Agung District, South Lampung Regency, in the 2025/2026 academic year. The application of educational games was carried out in the Islamic Cultural History learning process as a learning treatment. Data were obtained through learning achievement tests, observation, and documentation, then analyzed using inferential statistical techniques. The results showed differences in student learning outcomes after the implementation of educational game-based learning. The application of educational games was able to increase student engagement in the learning process and made a positive contribution to the achievement of Islamic Cultural History learning outcomes.

No full textLearning in the pesantren environment plays a strategic role in developing female students’ competencies through the internalization of Islamic values and local wisdom rooted in pesantren traditions. Pesantren local wisdom, which grows from long-standing traditions, cultural practices, and distinctive educational activities, constitutes an important potential for the development of contextual and meaningful learning. This study aims to describe the development of learning based on pesantren local wisdom in enhancing the competencies of female students at Hidayatul Mubtadiin Islamic Boarding School, Sidoharjo Village, Jati Agung District, South Lampung Regency, in the 2025/2026 academic year. This research employs a qualitative approach using a descriptive method. Data were collected through observation, in-depth interviews, and documentation involving the pesantren leader, female teachers (ustadzah), and female students as research informants. Data analysis was conducted through data reduction, data display, and conclusion drawing. The findings indicate that the development of learning based on pesantren local wisdom is implemented through the integration of pesantren traditions, role modeling by ustadzah, habituation of worship practices, and various pesantren activities oriented toward the formation of religious, social, and practical competencies of female students. This learning development has a positive impact on improving discipline, independence, moral character, and active participation of female students in both the learning process and daily life within the pesantren

Prinsip Pemberdayaan Umat Dalam Agribisnis
No full textCommunity empowerment in agribusiness is a strategic approach aimed at strengthening the capacity of local communities to manage agricultural resources independently, productively, and sustainably. This study examines the core principles of community empowerment—including self-reliance, participation, sustainability, and equity—and analyzes how these principles can be applied in community-based agribusiness development. Using a literature review method, this research synthesizes insights from books, scholarly journals, international institutional reports, and relevant policy documents. The findings indicate that community empowerment in agribusiness is not solely focused on increasing farmers’ income but also on enhancing their capacity through education and training, expanding access to technology and information, strengthening local institutions, and providing inclusive financing mechanisms, including Islamic finance schemes. Furthermore, transparent and integrative partnerships between farmers, government, the private sector, and religious institutions have been shown to create fairer and more competitive value chains. This study concludes that community empowerment in agribusiness is a multidimensional effort that generates economic, social, and ethical impacts, thereby serving as a crucial foundation for achieving food security, community self-sufficiency, and overall societal welfare
