Abstract

Mangrove is an ecosystem found in coastal areas and is influenced by the ebb and flow of sea water. This ecosystem has ecological, socio-cultural and socio-economic roles. The purpose of this study was to determine the level of damage to mangrove forests. This study used survey and line transect methods. Based on the results of the study in Palopo Village, 13 types of mangroves were found to be included in the station. Among them are, Bruguiera sp, Bruguiera sexangula, Rhizophora apiculata, Rhizophora mucronata, Ceriops tagal, Avicennia lanata, Sonneratia alba, Xylocarpus mollucensis, Lumnitzera racemosa, Calophyllum inophyllum L, Excoecaria agallocha L, Ceriops decandra and Bruguiera plaviflora. In accordance with the Decree of the Minister of Environment Number 201 of 2004 concerning the criteria for mangrove forest damage, the density of trees at stations I and II is included in the damaged category (rare) because the density is <1000 trees. For the canopy cover of mangrove trees, the Excoecaria agallocha L. species at station II obtained a coverage percentage of 50.23%, while the other 11 species obtained a coverage percentage below 50%. Based on the coverage criteria, the mangrove species Excoecaria agallocha L. is included in the good (moderate) category, while the other 11 species are included in the damaged category.

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.

Abstract

Research aims to improve students' science process skills by using the Discovery Learning learning model on biodiversity material. This classroom action research was carried out at SMA Negeri 1 Gorontalo. The instruments used in this research were observation sheets and written tests to measure students' science process skills. The research results show that using the discovery learning model can improve students' science process skills. This is proven by the results of the 6 indicators of science process skills, namely observing, classifying/grouping, interpreting, asking questions, hypothesizing and applying the concepts measured, getting an average percentage in cycle I of 70.42% and in cycle II amounting to 81.37%. with an N-Gain score obtained of 0.59 or a value of 0.3 ≤ g ≤ 0.7 (medium category). The achievement of student learning outcomes as measured by objective test questions also saw an increase in the average score in cycle I of 55% and in cycle II of 76%. Thus it can be concluded that the discovery learning learning model can be used in the learning process which can improve students' science process skills at SMA Negeri 1 Gorontalo and as information material, especially in the use of appropriate learning models in learning activities

Abstract

This research was calssifed as a Research and Development (R&D) that aimed to detemine the validity, practicality, and effectivenes of developing problem-based learning module to improve students’ learning outcomes. The samples consisted of 20 students in class X of SMA Negeri 7 PrasetyaGorontalo. This research was conducted to create module tahtreffered to the ADDIE model (Analysisi, Design, Development, Impelemntation, and Evaluation), but it was only limited to the development stage, namely the limited trial develpment stage. The instruments used were interview, validation sheet, and student response questionnaire, implementation of learning (teacher activity), student activity, and pre-test dan post-test. Teh result of module validation analysis with here validators obtained an average score of 85% (very valid). Meanwhile, the result of practicality analysis was observable from the teacher activity which obtained an average score of 93.3% (very good), the student activity in the small group trial obtained an average score of 90% (very good), and the student responses obtained an average score 88% (very feasible). In the meantime, the result of effectiveness analysis were observable from the result of N-Gain analysis in small group trial which obtained an average score of 0.62% (fairly effective). To conclude, the development of problem-based module on enviromental pollution topic intending to improve the students’ learning outcomes had met the valid and practical criteria but has not been effetive due to it only reached a limited trial. However, the module was feasible to use in the learning process.
