Abstract

This study aimed to determine the effect and identify the optimal sterilization pattern for suppressing contaminant growth in the in vitro culture of Sidikalang Arabica coffee (Coffea arabica L.) leaf explants. The experiment was conducted using a completely randomized design (CRD) with five treatment levels and 15 replications. Data were analyzed using the Kruskal Wallis test, and if significant differences were found, the Mann Whitney test was applied at a 5% significance level. The results showed that sterilization patterns significantly affected the time to contamination onset, the percentage of contaminated explants, the percentage of browning explants, and the percentage of explants forming callus. However, no significant effect was observed on the time of callus initiation. Sterilization pattern 5 was identified as the most optimal in suppressing contamination, with the lowest contamination percentage (6,6%), browning (6,6%), and the highest callus formation (93,3%). This pattern involved washing with detergent; soaking in Agrept (30 minutes) and Benlate (30 minutes); followed by sterilization in a laminar airflow cabinet (LAFC) using Tween 20 (20 minutes), graded Bayclin at 10%, 20%, and 30% (for 20, 15, and 5 minutes, respectively), 70% alcohol (20 seconds), and ascorbic acid (20 minutes).

Abstract

This study aims to analyze the visual representation aspects and level of representation in genetics textbooks related to DNA material. This study is descriptive qualitative with two genetics textbooks as the research objects. The analysis technique used is visual representation function analysis and level of representation. The results of the analysis show that visual representation is dominated by illustrative functions (70-75%), followed by complementary functions (23-25%), while explanatory functions only appear 5%, and decorative functions are not found. The level of DNA topic representation falls under the molecular level of representation. This finding indicates that the visual representations in both genetics textbooks are predominantly illustrative, followed by complementary functions, while explanatory functions appear only to a limited extent, and decorative functions are absent. This analysis provides valuable insight into the quality of the textbooks and their relevance to potential student misconceptions. The implication of this study is that it can serve as a reference for authors of genetics textbooks, particularly in the topic of DNA, to pay closer attention to the balance of visual representation functions, ensuring that no single function dominates and that the visuals more effectively support students’ conceptual understanding.
