Developing enrichment module of polyploidy on shallot (Allium ascalonicum L.) for 12^th grade students

The objectives of this research were to determine the effect immersion duration and concentration of colchicine on polyploidy of shallots (Allium ascalonicum L.), to develop enrichment module based on the study, and to assess the enrichment module feasibility based on assessment of material experts, media experts, biology teachers, and responses of students. The research was development research using ADDIE model limited to development stage. Data of the study was the description of chromosome counting. The module feasibility data was obtained from the assessment by the reviewers and the responses of the respondents. The module feasibility assessment data was processed into quantitative data. The aspects analysed include the assessment of appropriateness of the concept, feasibility of content, presentation, language, and graphic. The results showed that colchicine's immersion duration and concentrations had effects on polyploidy of shallots. The results of the research were used to develop module of mutation learning based on 2013 curriculum. Module review from material experts showed that most of the module's substances were appropriate. Module review from media experts and responses of students showed that the module was feasible, and from biology teachers was highly feasible. The overall assessment results showed that polyploidy module was eligible feasible as teaching material in enrichment program for 12^th grade students.
