Abstract:
This development research has the aim of describing the practicality of the
popular scientific book on ethnobotany Myrtaceae Forest Areas with Special
Purposes (KHDTK) ULM which is an education and training forest under the
institution of Lambung Mangkurat University. This popular scientific book
(BIP) was developed through Tessmer's Formative Evaluation, while the stages
carried out were conducting a self-evaluation, followed by expert validation,
student readability test (one-to-one evaluation), Small Group Test, and Field
Test. The results of the practicality test of the contents of the one-to-one
evaluation get an average value of 95.51% with very good criteria. Based on the
results of the implementation test, the expectation was to get a percentage of
88.89% and the actual 92.22% was expected with very good criteria. the
students' s response was expected to get a percentage of 96.80% and the actual
97.40% with very practical criteria. Based on the results of the research
developed, it can be stated that the Popular Scientific Books (BIP) developed
can be used in improving students' critical thinking skills because the scientific
books developed have very practical criteria
