Abstract

The National Science Olympiad (OSN), which in 2020 changed its name to the National Science Competition (KSN), is held in stages to motivate students, teachers, managers and education coaches to compete healthily in order to improve the quality of national education. In the field of science, in previous years the results in Kolaka Regency were still in the low category, including SDN 1 Lamokato. In the academic year 2019/2020 SD Negeri 1 Lamokato will send again its students to take part in the 2020 KSN.Therefore, there needs to be preparation early, one of the preparation iswith the Community Service program by a team of lecturers and students of the Biology Education Study Program, Sembilanbelas November Kolaka University. which was carried out in the form of providing learning guidance for KSN-SD preparation. PkM activities include the stages of preparation, implementation and evaluation. The preparation stage includes curriculum analysis and OSN questions and giving pretest questions. The implementation stage includes the provision of material about OSN, guidance and assistance in solving OSN questions, and the evaluation stage includes giving posttest questions and questionnaires at the end of the activity. The results of the implementation of PkM tutoring for the National Science Competition (KSN-SD) at SD Negeri 1 Lamokato went smoothly and had a positive impact on the preparation for the KSN-SD students in 2020. This result was shown by the increased ability of participants to solve Olympic questions (from scores the average pretest 45.83 to 75.0 at posttest). The results of the evaluation questionnaire analysis also showed that the participants were motivated (83.33%), the participants' understanding of the material and the supervisor's ability to provide the material was considered very good (88.89%). However, additional time is needed in mentoring and mentoring participants who will take part in the KSN-SD selection so that this activity can provide an optimal contribution.

Abstract

The village of Lamundre is an area overgrown with a mangrove ecosystem of 4 hectares and is well developed on the coast. The area can be well overgrown with mangroves because of environmental conditions and other supporting factors such as muddy substrate, muddy sand in tidal transition areas, salty, brackish water and the presence of currents/waves that are classified as mangrove growing conditions. This study aims to determine the types of mangrove plants and environmental parameters on the abundance of mangrove species on the coast of the Rainbow Bridge, Lamundre Village, Watubangga District, and Kolaka Regency. This type of research is descriptive and qualitative by using mangrove samples on the roots, stems, leaves, flowers and fruit. The method used is Line Transect, which uses plots that are aligned on the main line (Basseline) that has been determined in the research area along 280m, the total number of plots is 10, with each plot of 10m x 10m.  Based on the study's results on the identification of mangroves in the Pantai Pelangi Beach, Lamundre Village, Watubangga District, and Kolaka Regency, it shows that mangroves belong to 2 families and                 7 species. The mangroves are from the Rhizophoraceae family namely Rhizophora mucronata species, Rhizophora apiculata, Rhizophora stylosa, Ceriops decandra, Bruguira cyndrica, Bruguira ghymnorryza and the Soneratiaceae family namely Soneratia caseolaris. Keywords: Lamundre village, identification, mangrovee
