Abstract

One of the mangrove forests in Indramayu, West Java, Indonesia that plays an essential role in the environment and becomes a learning center, is the Karangsong mangrove forest. The study aimed to determine the feasibility and effectiveness of Enrichment E-Module of Mangrove Ecosystem (EMME) to improve students' self-regulated learning. This study was Research & Development with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). This study was conducted at a Senior High School in Sindang, Indramayu, Indonesia with ten (X) grade of science class. The samples were chosen using a purposive sampling technique, resulting in class X-7 chosen as a control group and class X-8 as an experimental group. The design of this study used a non-equivalent control group design. The average validation result by experts was that media expert of 87.75 (very feasible), material expert of 94.36 (very feasible), and biology teacher of 93.40 (very feasible). The results indicated that the enriched e-module of the mangrove ecosystem was feasible in enrichment learning. E-module did not significantly influence to improve students' self-regulated learning, as seen from the result of the Mann Whitney test (0.077). Improvement of students' self-regulated learning was low, as seen from the N-gain score of the control group (0.06) and the experimental group (0.20). These concluded that the e-module of the mangrove ecosystem could be used in the learning, and short time allocation causes the module not to influence self-regulated learning significantly. Several revisions are needed in order to make the e-module more effective in improving students' self-regulated learning.

Abstract

The Serawai tribe is one of the indigenous tribes who live in the Bengkulu Province. The Serawai people still use medicinal plants because of the high trust of the Serawai people towards traditional medicine. Local plants have enormous potential to be developed as a source of learning biology. Therefore, the purpose of this study was to obtain information about the species of plants used by the Serawai tribal community in Tanjung Aur Village, Bengkulu as medicinal plants that have the potential as learning resources in biology learning at the high school level. The ethnobotanical studies covered include plant species, plant families, organs used, processing methods, and use value indexes (UV) for each plant. The ethnobotany study in this research used a qualitative descriptive-analytical method. Based on the results of the ethnobotanical study, there are 44 species of medicinal plants and 23 families. The most widely used plant part is the leaf with a percentage of 52.27%. The highest Use Value is Kaempferia galangal L from the Zingebareceae family. Based on the curriculum, the results of the investigation of medicinal plants can be used as teaching materials in biodiversity and plant topics for the grade of 10-th of high school. Teaching materials can form to be learning modules of medicinal plants.
