Abstract

Plant morphology plays a crucial role in biological education, yet it often faces challenges regarding the effectiveness of its learning models. This preliminary study aims to identify student needs in plant morphology learning. A survey method was used to collect data on student opinions, understanding, difficulties, and attitudes after completing the plant morphology course through a questionnaire. The study was conducted from December 2024 to January 2025. The sample selection used a purposive sampling technique, with 128 respondents consisting of Biology and Biology Education students at UAD. Data were collected using a Google Form-based questionnaire. Research variables were measured using a Likert scale, along with binary yes/no options to assess respondents' agreement with various statements, as well as several open-ended questions. The study results show that 99% of students consider plant morphology an important course. However, students still find difficulties in learning plant morphology, particularly in the topics of flower parts, floral formulas, and floral diagrams (55.5%). The study found that students prefer environmental learning resources to better master the material. Practical and observational methods were selected by 84% of students as preferred learning. Furthermore, 90% of students emphasized the importance of outdoor learning experiences due to direct involvement with nature, and 86% expressed willingness to participate. Thus, it can be concluded that a learning model incorporating outdoor experiences is needed for plant morphology courses

Abstract

This research is an exploratory study conducted in Batang Regency. The research samples, namely bitter mustard (Brassica juncea L.) and petsai (Brassica pekinensia L.) leaves, were collected in December 2022. The selection of research samples is based on the level of production and availability. The data analysis method used in the research is descriptive quantitative analysis. The results showed that bitter mustard (Brassica juncea L.) and petsai mustard (Brassica pekinensia L.) have the same epidermal characteristics, namely irregularly shaped epidermal cells with notched cell wall edges and elongated polygonal cells with flat cell wall edges. The epidermal derivatives found are stomata and trichomes. The stomata of the study sample have anisocytic type, closed slit condition, but have different sizes (length and width), index and density. Trichomes have a simple needle-like hair type on the edge of the leaf, but have different sizes (length and width). The differences in the research samples can be observed quantitatively.
