Pengujian Infusa Rebusan Bunga Telang (Clitoria ternatea) Sebagai Pewarna Alami Sediaan Apus Darah Tepi (SADT)

Fajar Husen, Nur Aini Hidayah Khasanah — Mon, 31 Jul 2023 00:00:00 +0000

Telang flower (Clitorea ternatea) is a flower that belongs to the endemic plants that are often found in Ternate. C. ternatea belongs to the Fabaceae family of leguminous plants and is the world's most prominent family of flowering plants. C. ternatea contains a lot of blue pigments or cyanos known as anthocyanins. These dyes have great potential as alternative dyes to replace methylene blue and are potential blood cell dyes. This study aimed to examine the potential of the anthocyanin content in the butterfly pea flower infusion as a natural differential dye for erythrocytes and leukocytes. This research method is descriptive in nature, in which the results of making cytological preparations in the form of capillary smears of human blood are stained with butterfly pea flower infusion at a concentration of 10%. The stained spots were then observed using a light microscope at 400x magnification. The colouring results of butterfly pea flowers were compared with a standard dye, Giemsa dye. The results showed that a 10% concentration of butterfly pea flowers stained erythrocytes but did not stain leukocytes well, while Giemsa's staining significantly stained well. The results also showed that butterfly pea flower infusion could only differentiate stained erythrocytes and unstained leukocytes but could not differentiate the types of leukocytes. Further research can be carried out by extracting anthocyanins from butterfly pea flowers and fractionating them to isolate single anthocyanin compounds that can potentially be dyed.

Non-violence education is a progressive approach to educational transformation that deeply reveals the vulnerabilities, failures and practices of violence in multiracial coexistence. As an educator, a teacher must be cool and service-oriented to children at school. Because the teacher's social status should not be considered as the cause of educational development, because it is in their hands that the nation's children will be educated and educated to maturity. Therefore the government must seriously prepare reliable and professional teachers who also understand the character of students and are anti-violence. However, it should also be remembered that the role of parents in transforming their children into human beings who care about the environment, upholding human and ethical values is also very important. The method used in this study is a qualitative method, this method was chosen because it aims to determine how to find, collect, process, and analyze data from the results of the research. Anti-violence education is not only the responsibility of the government or educational institutions, but also the responsibility of all members of society. Collaboration and participation of various parties is the key in creating a safe and peaceful environment for all individuals. By prioritizing non-violence education, we can build a society that is more dignified, full of respect and appreciates differences.
