PERBANDINGAN LARUTAN BUAH PINANG (Arecha catechu L) DAN DAUN SIRIH HIJAU (Piper betle L) TERHADAP KEJELASAN JARINGAN HATI SEBAGAI ALTERNATIF PEWARNA ALAMI PREPARAT JARINGAN SEBAGAI SUMBER BELAJAR BIOLOGI

Abstract

Fruit Arecha catechu L and leaf Piper betle L are plants that contain
pigments that can be used as natural dyes for tissue preparations. This study
aims to determine the differences in liver tissue clarity using natural Arecha
catechu L and leaf Piper betle L, determine the natural coloring solution of
Arecha catechu L and Piper betle L the best for the clarity of tissue
preparations and research results can be used as a source of high school
biology learning in the form of practical instructions.
Research conducted at the Integrated Science Laboratory of the
Universitas of Muhammadiyah Metro in May 2019, the results of a photo
analysis of liver tissue preparations with natural dyes fruit Arecha catechu L
obtained percentage on criteria 1 "very clear and very contrast" (46.66%),
criterion 2 "unclear and contrastless" (40%) and criterion 3 "unclear and
non-contrasting" (13.33%), while the percentage results obtained on photos of
liver tissue preparations with natural dyes of leaf solution Piper betle L in
criterion 1 "very clear and very contrasting" (40%), criterion 2 "unclear and
less contrasting" (40%) and criterion 3 "unclear and not contrasting" (20%).
The results of this study were compiled as a source of learning biology in the
form of practical instructions and validated by two expert lecturers, obtaining
an average percentage of 88% with the criteria of "Very Good".
