Abstract

This study aims to examine the limitations of human resources (HR) in school laboratories and their impact on the implementation of biology practicum activities at the senior high school level. A descriptive qualitative method was employed in Kotagede District, Yogyakarta, using purposive sampling to select two schools with active biology laboratories. Data were collected through in-depth interviews with laboratory personnel and biology teachers to explore the availability, involvement, and roles of laboratory staff in supporting practicum activities. The findings revealed significant differences between the two schools. School A had a complete laboratory staff, including a head of the laboratory and a laboratory assistant, which allowed practicum activities to be conducted in a structured and systematic manner, effectively supporting students' conceptual understanding and scientific understanding. supporting students' conceptual understanding and scientific skills. In contrast, School B lacked laboratory personnel, resulting in all practicum responsibilities being assigned to the biology teacher, which led to suboptimal implementation and limited student learning experiences. Therefore, efforts to increase the availability and competence of laboratory personnel in accordance with national standards are necessary. The presence of professional laboratory staff plays a crucial role in creating effective, meaningful, and skill-oriented biology learning through practicum-based approaches.

Abstract

The Anatomy of Tekokak (Solanum torvum Sw.) is a plant that grows wild in the forest and its fruit is used as a vegetable. This study aims to complete the study of the anatomical structure of tekokak and identify typical microscopic characteristics that can be used as specific markers. This research is important in order to contribute to the scientific documentation of local plant taxonomy and support the utilization of plants in the fields of pharmacy, conservation, and as an a reference for botanical education in Biology. The research data were analyzed using a qualitative descriptive method by comparing the characteristics of the samples found with references. The results of this study include image data and qualitative descriptive data obtained from the anatomy of the roots, stems and leaves of Solanum torvum Sw The root of S. torvum Sw. consists of the epidermis, exodermis, a cortex layer made up of cortex parenchyma, endodermis with Casparian strips, a pericycle or pericambium layer, special medullary ray structures, and vascular tissues, xylem, and phloem. The stem part is composed of an epidermis with star-shaped non-glandular trichomes, lamellar collenchyma, cortex, endodermis layer, pericycle, vascular tissue comprising xylem and phloem, and pith. The anatomical difference between unbranched and branched stems lies in the arrangement of the vascular bundles, the thickness of the supportive tissue, and the complexity of the vascular tissue, indicating structural adaptations to the position and function of the stem. On the stem found scalariform trachea, annular trachea, reticulate trachea, thickened reticulate trachea, tracheid, fiber tracheid and libriform fiber. The leaf cross-section shows adaxial epidermis with cuboid-shaped cells and anisocytic stomata, palisade parenchyma, spongy parenchyma, abaxial epidermis with anomocytic stomata, and non-glandular star-shaped trichomes.

Abstract

This study aims to identify the proportions and types of visual representations in Grade XI Biology textbooks, specifically on the topic of the Human Locomotion System. Visual content in Biology textbooks plays a crucial role in facilitating students’ understanding of biological concepts; however, previous studies have shown that such content remains limited in depth and rarely connects biological material to real-life contexts. The objective of this research was to examine the functions and forms of visual representations in selected textbooks, and to evaluate their alignment with principles of effective visual representation. Employing a qualitative content analysis approach, four textbooks were analyzed using a classification framework that classified the visual representations by their function (decorative, illustrative, explanatory, complementary) and by their form (e.g. illustrations, diagrams, tables, maps). The results revealed that visual representations were predominantly illustrative in both function and form across all Biology textbook samples. Among the samples, the YT textbook demonstrated the highest quantity and diversity of visual content, while KM had the fewest. These findings suggest that the textbooks have not fully adhered to the principles of effective visual representation, which may limiting students’ understanding of complex biological concepts. It is recommended that future editions increase both the quantity and variation of visual content to enhance pedagogical effectiveness and promote deeper learning.
