Abstract:
The development of the popular scientific book Ethnobotany of the Bungur plant
(Lagerstroemia speciosa) is important because it can raise the local potential of the
community in the Bukit Tamiang area and as an enrichment material for the
Ethnobotany course in the ULM Biology education program. This study aims to
describe the ethnobotany study of Bungur (Lagerstroemia speciosa) in the Bukit
Tamiang forest area, Tanah Laut Regency, South Kalimantan and to describe the
validity and practicality of the contents of popular scientific books. This method uses
two types of research, namely descriptive research, interviews with the public about
the Bungur plant and followed by the formative evaluation of the Tessmer test for
validation and practicality of the contents of Popular Scientific Books. The results of
research on Bungur plants (Lagerstroemia speciosa) in the Bukit Tamiang forest area
have various studies including botanical, ethno-ecological, ethno-pharmacological,
ethnoanthropological, ethno-economic, and ethno-linguistic studies. The conclusion
from the development of a popular scientific book on the study of the ethnobotany of
the Bungur plant (Lagerstroemia speciosa) is that expert test results were obtained
by two validators with an average value of 90.3% with very valid criteria and the
results of the practicality of the content on individual tests by three students getting
average results. percentage 3,7% with very good criteria. The advantages of
developing a popular scientific book on the ethnobotany study of the Bungur plant
(Lagerstroemia speciosa) can be used by students as an enrichment material for
Ethnobotany courses and can be read by the wider community because this popular
scientific book developed is structured in such a way that it is easily understood by
readers. However, the weakness is that the learning material contained in this
developed book is insufficient so that further research is needed
