Abstract

Wasti lake in Manokwari is one of the mangrove forest areas located on the coast of Manokwari and has ecological, economic and socio-cultural potential. Development continues, land conversion for settlement and economic development will have a negative impact on the sustainability of the mangrove ecosystem in Wasti Lake. Thus, this study aims to determine the vegetation structure of the mangrove forest at Telaga Wasti and its ecological potential to prepare teaching materials for ecology courses at the Biology Education Study Program, University of Papua. This research was conducted in May - July 2022. The method used is the line method (transect line) and the quadratic method. Data was collected on plots measuring 20m x 20m for tree vegetation, 10m x 10m for pole vegetation, 5m x 5m for saplings and 2m x 2m for seedlings. The results of data analysis showed that the mangrove vegetation structure consisted of 7 species from 4 families. The highest INP at tree level for both stations was Sonneratia alba, while the highest INP for pole level at station I was Rhizophora stylosa and station II was Sonneratia alba. The highest level of sapling at station I INP was Rhizophora stylosa and at station II the highest INP was R. apiculata. Then the highest INP station I seedling vegetation was R. stylosa and the highest INP Station II was R. apuculata.

Abstract

This study aims to produce a valid and practical teaching module for the concept of mangrove plant taxonomy in Saubeba Bakau Bay, Manokwari City. The research method is Research and Development (R D). This study uses the ADDIE model with stages of Analysis, Design, Development, Implementation and Evaluation. Mangrove diversity data was collected by exploration and documentation methods, validity and practicality data were obtained from material experts, media experts, lecturers' and students' responses. To determine the percentage of validity and practicality of the module, the results were obtained from the calculation of the total score obtained divided by the maximum score multiplied by one hundred percent. The results showed that there were three types of mangrove plants found in Saubeba Bakau Bay: Avicennia alba, Rhizophora apiculata and Sonneratia alba. The results of the validation of the teaching module based on media experts showed that the developed module was very feasible with an average percentage value of 84%. The results of the assessment based on material experts obtained an average percentage value of 96% with a very feasible category. The results of the lecturer response assessment obtained an average percentage of 96.5% with a very practical category. The results of the student response assessment obtained an average percentage of 93%, indicating that it was very practical. Therefore, the developed teaching module is very feasible and practical, making it suitable for use in the learning process.
