Abstract

The structure and function of plant tissue was difficult material for students to learn, especially in identifying plant tissue due to limited laboratory facilities such as plant tissue preparations. Learning media could help students in overcoming these problems that could display plant tissue clearly. The atlas media contained anatomical pictures of the leaves of six types of dicot ornamental plants which could help students to observe plant tissues. This study aimed to determine the validity of the leaf anatomy atlas media of six types of dicot ornamental plants in the structure and function of the sub-material of plant tissue in class XI. The research method was quantitative descriptive. Progress in making atlas consists of pre-production, production, and post-production. The media atlas was validated by five validators with a Likert scale (1-4). The validated aspects were presentation, content, language, and usage with 21 criteria. The data were analyzed using Laswhe method. The results of the validation showed that the aspects of language and usage obtained reached the minimum value of the Lawshe index of 0.99 but the presentation and content aspects have not reached the minimum value of the Lawshe index. The results of the validation show that the atlas media was not yet valid, especially in terms of presentation and content, so the atlas needs to be revised before being used in the classroom.

Abstract

Climate change causes drought in many places, including tropical areas, which affects ornamental plants both in morphology and anatomy. Codiaeum variegatum (L.) Rumph. ex A.Juss. and Excoeceria cochinchinensis Lour have low transpiration rates and allow them to be resistant to drought. This study aims to observe the morphology and anatomy of C. variaegatum and E. cochinchinensis leaves due to drought stress. The experimental design was a factorial completely randomized design (2x2) with 3 replications. The main factors are two types of plants and two conditions namely control and drought. The combination was the interaction between the two main factors. Observations included descriptions of leaf blades and edges every week for four weeks. Stomata changes, description of stomata and leaf anatomical tissue were counted and measured using a microscope connected to optilab. Observation results showed changes in the appearance of leaf blades and leaf rolling. Stomata and SD varied as well as the thickness of leaf tissue which was differentiated in both thickness and shape. The conclusion of this research was that C. variaegatum was a drought tolerant plant and E. cochinchinensis was low tolerant. Both plants can aprropriately be used to green the area with water constrain as well as ornamental plants.
