One of the Basic Competencies (KD) in Biology for Indonesian Senior High School is KD 4.12 which reads "Presents observations of the process of mitosis in the onion root and determines the phases it finds". Based on the basic competency test, students are required to have skills in making and observing mitotic preparations of plant tissue with at least using onion. Observation of mitotic division in plant tissues requires skill in making preparations. Making preparations in observing cells and tissues of plants or animals needs staining. Dyes often used in lab work are synthetic dyes. One of the synthetic dyes commonly used is safranin. However, safranin is quite expensive. This limitation requires teachers to look for alternatives to synthetic dyes that are easily found at a more affordable price, namely with natural dyes. One of the plants that has the potential to overcome this issue is beetroot (Beta vulgaris). The purpose of this study was to determine the quality of plant tissue preparations (Allium cepa) stained with beetroot skin (Beta vulgaris) as a natural coloring agent. The research method used was an experimental method with a Completely Randomized Design consisting of two factors, namely the staining time (1 hour, 2 hours, and 3 hours) and the type of solvent (aquades and citric acid 10%). The results of the study were analyzed with qualitative descriptive methods which included contrast and clarity of the preparations. Based on the results of the study, the quality of Allium cepa root preparations using beetroot (Beta vulgaris) skin extract with variations in the type of solvent and duration of staining showed good results on the staining time of 1 hour and 2 hours. The staining time of the preparations can affect the contrast and clarity of the preparations.

Indriyani et al, (2013) stated that many students had dificulty in understanding the generic structure of analytical exposition text. Therefore, the present study tried to investigate the correlation between students understanding in writing generic structure of analytical exposition and the quality of students’ writing in second grade of senior hight school. Grounded in explanatory correlational research design by Creswell (2011), this study conducted over two weeks in one of senior high school in Indramayu. Close-ended questionnaire and writing test were instruments to collect the data and it was analyzed  by using SPSS 22. The statistical calculation from students understanding in writing generic stucture of the text and writing test indicated that the value of tcount was 3.23 and the value of ttable was 0.361. It can be concluded that the hypothesis was accepted because tcount 3.23 > ttable 0.361. The finding reveal that there was middle correlation or middle prediction in students understanding of generic structure of analytical exposition and students writing quality with the score 0,52.
