Abstract

Biology learning needs to support sustainable development. This research was a quantitative-qualitative sequential explanatory mixed research. This research aimed to obtain information about the relationship between naturalist intelligence and environmental responsibility behavior. This research was conducted in February-August 2019. Quantitative research data were obtained by using a questionnaire with a Likert scale for the variables. Qualitative research data were obtained by doing interviews and observations. Quantitative data were analyzed using descriptive statistic calculation. The data hypothesis was tested by using a correlation test with the Product Moment Pearson formula. The result of this research showed that there was a positive relationship between naturalist intelligence and environmentally responsible behavior with regress equation Ŷ = 20.331 + 0,7524X. Correlation coefficient (r) = 0.66 and determination coefficient (r²) = 43.56% meant that the interpretation value was strong. r² value means that 43.56% environmentally responsible behavior correlates by naturalist intelligence and 56.44% environmentally responsible behavior is influenced by other factors. Biology learning must have a role to be able to provide innovations related to increasing students' knowledge about the environment. This study concludes that there is a correlation between the two variables.

Abstract

This research aims to determine the vitamin C potential of tree sorrels (Averrhoa bilimbi) as a natural latex coagulant. The researchers employed the Completely Randomized Design (CRD) method. The method consisted of three repetitions with five treatments, namely negative control (without clotting) and positive control, by administering tree sorrel extract (Averrhoa bilimbi) with a volume of 5 ml, 10 ml, 15, and 20 ml. The researchers tested the vitamin C levels using UV-VIS Spectrophotometry DR 6000 with a wavelength of 265 nm to 271 nm. Furthermore, the data were analyzed using the One-Way ANOVA statistical test and the LSD to determine the most effective volume as a latex coagulant. The quantitative data were the clotting time and latex weight. The results showed that tree sorrel extract could be used as a latex coagulant. The fastest duration (1.18 minutes) and the highest weight (34.30 grams) of latex were found in the 20 ml volume. At the same time, the lowest yield was at a volume of 5 ml with a clotting time of 5.4 minutes and a weight of 18.62 grams.
