Abstract

This study aims to develop a Crossword Puzzle learning media based on the Puzzle Maker application as an evaluation tool for environmental change and conservation material in class X MAN 1 Boalemo. The background of this study is based on the low level of student involvement in biology learning which is still dominated by conventional methods, so that students have difficulty understanding abstract concepts. The research method used is Research and Development (R&D) with the Plomp development model which includes three stages, namely preliminary research, prototyping phase, and assessment phase. The subjects of this study were 22 students of class X MAN 1 Boalemo, and one biology teacher. The instruments used included expert validation questionnaires, student response questionnaires, teacher response questionnaires, and observation sheets for learning implementation. The results showed that the validity of the media was in the very valid category, with an assessment from material experts of 86% and a media expert of 96%. The practicality of the media was also assessed as very good based on the learning implementation reaching 93-95%, student responses with a percentage of 85%, and teacher responses of 93%. Thus, the Puzzle Maker-based Crossword Puzzle media is declared feasible and practical to use as an evaluation tool, and has the potential to increase student involvement in biology learning.

Abstract

This study aims to determine the composition of vegetation types in the karst area of Gorontalo province and determine the vegetation structure in the karst area of Gorontalo province. The method used in this study uses the square transect method, the transect line is made perpendicular along 100 m, with the plot size being 20 x 20 m for tree strata, 10 x 10 m for pile strata, and 5 x 5 m for seedling strata, The results of vegetation structure analysis based on the highest INP value for tree-level strata at station I are Leucaena leucocephala species 2.20%, at Ceiba petandra station II 1.24%, and at Muntingia calabura station III 1.72%. At the stake level, the Leucaena leucocephala species had the highest INP value of the three stations, which was 1.81%. For the nursery rate, the highest INP is owned by the Leucaena leucocephala species at 2.10%. Based on the results of the analysis using ordinance charts, stations II and III have almost the same formation pattern so that the graph tends to overlap, while for station I it is very different from stations II and III, for station I it has its own formation pattern compared to stations II and III, and station I is also indicated to have its own characteristics based on habitat conditions and environmental factors.
