Abstract

This study aims to observe the effect of Indole Butyric Acid (IBA) concentration and coconut water on the growth of orchid plant shoots of Cattleya sp. In vitro using the tissue culture method. The research was conducted at the YAHDI Tissue Culture Laboratory from March to July 2024. There were 9 treatments with a combination of IBA concentrations (0, 1, 2 mg/l) and coconut water (0, 50, 100 ml/l), which were repeated 3 times each, resulting in a total of 27 experimental units. The variables observed included the time of emergence of shoots, the number of shoots, the number of leaves, and the height of the plantlet. The results showed that a coconut water concentration of 100 ml/l provided the best bud growth, while an IBA concentration of 1 mg/l and coconut water of 100 ml/l produced the highest number of leaves. However, variance analysis showed that the application of IBA and coconut water did not have a significant effect on the number of shoots, the number of leaves, and the height of orchid plantlets at the age of 6 MST. Observations showed that the interaction between IBA and coconut water was not optimal enough to stimulate bud growth, and the use of younger orchid leaves gave the best results. This study provides insight into the use of coconut water in tissue culture to improve the growth of Cattleya orchids, although its effectiveness is still limited to certain concentrations.

The interactive simulation is embedded in the LMS used by Unimed in the learning process, and this is called Sistem Pembelajaran Daring (Online Learning System). This study presents the effectiveness of implementing virtual laboratories through interactive simulations in a Basic Mathematics course during online learning. The effectiveness is seen from two approaches, namely qualitative and quantitative approaches. Qualitatively, the interactive simulation has been validated by media experts and material experts. Then, the simulation was carried out with students through LMS, and after that, the students were asked to fill out a response questionnaire related to the interactive simulation with a 5 rating Likert scale. The results indicate that good responses were obtained from students in that the average score reached 4,23. Quantitatively, a test of the difference in the increase in the value of learning achievement was carried out on students who were taught using interactive simulations, and students who were not taught using interactive simulations. The data obtained were tested by t-test through SPSS. The results show that there is a significant difference in the achievement of learning scores between students who were taught using interactive simulations and students who were not taught using interactive simulations. Therefore, it can be concluded that virtual laboratory activities through interactive simulations are effective. Keywords:Effectiveness of virtual laboratories, Interactive Video, Software Maple

Abstract

Animalia learning in high schools is still dominated by general textbooks that rarely integrate local biodiversity, resulting in limited cognitive learning outcomes. This study aimed to develop a Crustacea Booklet of Ujung Patikalo Beach as a learning resource for Animalia and to evaluate its validity, practicality, and effectiveness. This Research and Development (R&D) study employed the 4D model (define, design, develop, and disseminate). The study involved six expert validators, one biology teacher, and two Grade X classes of SMA Negeri 1 Tukka as the experimental and control groups. Data were collected through observations, interviews, questionnaires, documentation, and cognitive achievement tests. The booklet was rated highly valid by experts (87.01–91.73%) and received very positive responses from the teacher and students (91.66–99.00%). The experimental class achieved a high N-Gain score (0.71), exceeding that of the control class (0.39). The Independent Sample t-test indicated a significant difference in cognitive learning outcomes between the two groups (p < 0.05). These findings demonstrate that the developed booklet is a valid, practical, and effective local potential-based learning resource for improving students’ cognitive learning outcomes in Animalia.
