Local Potential of West Kalimantan's Mangrove Ecosystem as A Study Material in Biology Education at Mangrove Area School

Abstract

West Kalimantan has the local potential of mangrove ecosystems to become a source of biology education. Utilizing the local potential as a source of learning provides opportunities for students to understand phenomena directly from nature so that they can foster environmental care attitude. This research aims to create a sudy material in the form of student worksheets or Lembar Kerja Peserta Didik (LKPD) based on the local potential of the mangrove ecosystem in West Kalimantan. The method used in this research was the Four-D (4D) Research and Development model proposed by Thiagarajan. The data were collected through validated questionnaires and student response questionnaires. The results showed that the developed LKPD was feasible to use, seen from the results of the validator's assessment with an average value on each aspect at 87.60% (very valid category) as well as the practicality value of the students' responses with an average value on each aspect at 86.14% (very good category). The developed LKPD can also enhance the understanding in biology education about mangrove ecosystems and fostering an environmental care attitude and scientific attitude. Hence, it becomes a solution to anticipate environmental damage in Indonesia, especially through the mangrove forest conservation area in West Kalimantan.
