Abstract

This study objectives to theoretically analyze the morpho-physiological responses of mustard greens (Brassica juncea L.) to micro-environmental engineering and to formulate an efficient agronomic strategy based on a compilation of prior research data. The method used was a literature review by synthesizing secondary data from various scientific journals related to edaphic porosity manipulation and organic Nitrogen nutrient optimization. The results of the review show that edaphic engineering using porous materials such as husk biochar is consistently proven to enhance oxygen circulation in the rhizosphere, which increases the efficiency of active transport nitrate ion absorption. Optimal Nitrogen accumulation accelerates cell division in leaf mesophyll and increases chlorophyll concentration, thereby boosting carbon assimilation rates during the rapid vegetative phase (30–40 days). The implication of this study is the availability of a sustainable conceptual model for leafy vegetable horticulture cultivation using local organic materials. Based on the literature synthesis, stable micro-environmental manipulation is proven crucial to maintaining high turgor in amfistomatic guard cells, producing wide, fresh, and crispy leaves.

Abstract

Food processing technology plays a crucial role in improving food quality, safety, and shelf life amid the growing demand for safe, nutritious, and sustainable food products. Various processing methods, ranging from conventional techniques to advanced technologies, have been developed to maintain product quality while minimizing spoilage and contamination risks. This article aims to examine the role of food processing technology in enhancing food quality, safety, and shelf life through a literature review approach. Data were collected from scientific journals, books, research reports, and other relevant academic sources related to food processing technology. The reviewed literature indicates that processing technologies such as heating, cooling, freezing, drying, fermentation, canning, and modern packaging effectively preserve the physical, chemical, sensory, and microbiological characteristics of food products. These technologies also contribute to controlling pathogenic microorganisms, reducing post-harvest losses, improving product stability, and extending storage periods. Furthermore, recent innovations, including modified atmosphere packaging and non-thermal processing technologies, provide additional opportunities to improve food quality while maintaining nutritional value. In conclusion, food processing technology is an essential component of modern food systems, supporting the production of safe, high-quality, and sustainable food products while contributing to food security and reduced food waste.

Abstract

Teacher professionalism and competence are crucial elements in ensuring the effectiveness of educational management and improving the quality of education. Teachers are expected to possess professional attitudes and competencies that support effective teaching and learning processes. This study aimed to analyze teacher professionalism and competence within the perspective of educational management at SMP Negeri 2 Gunungsitoli Utara. A qualitative descriptive method was employed to obtain an in-depth understanding of the phenomenon under investigation. Data were collected through interviews, observations, and documentation, with the school principal serving as the primary informant. The collected data were analyzed using the Miles and Huberman model, which includes data reduction, data display, and conclusion drawing. The findings indicate that teacher professionalism is reflected in responsibility, discipline, commitment to teaching duties, active participation in school programs, and efforts to improve instructional quality. Teachers generally demonstrate adequate pedagogical, professional, social, and personal competencies, although differences in competency levels among individuals remain evident. Educational management plays an important role in supporting teacher development through supervision, training programs, professional development activities, performance evaluation, and the provision of a conducive working environment. Furthermore, the principal contributes significantly to fostering teacher professionalism and competence through guidance, monitoring, and continuous support. The study concludes that effective educational management contributes substantially to strengthening teacher professionalism and competence, thereby enhancing the overall quality of education at SMP Negeri 2 Gunungsitoli Utara.
