Abstract

Penelitian ini bertujuan untuk menghasilkan produk lembar kerja peserta didik berbasis ekosistem mangrove melalui model project based learningyang dapat membantu meningkatkan pemahaman konsep siswa pada materi ekosistem di SMAN 1 Lembar. Metode penelitian yang digunakan adalah Research and Development (R&D) dengan menggunakan model ADDIE (Analysis, Design, Development, Implementation, and Evaluation) Dalam penelitian ini yang menjadi populasi penelitian adalah seluruh kelas X MIPA dengan jumlah siswa sebanyak 131 siswa. Sampel pada penelitian ini diambil dengan teknik purposive sampling dan diperoleh kelas X MIPA 4 sebagai sampel penelitian berjumlah 33 orang dengan menggunakan uji coba lapangan terbatas. Sebelum dilakukannya uji coba lapangan terbatas, terlebih dahulu dilakukan uji coba kelompok kecil pada siswa kelas X MIPA 2 dengan jumlah siswa sebanyak 10 orang. Berdasarkan hasil temuan, validasi lembar kerja peserta didik oleh validator memiliki presentase rata-rata sebesar 79.61% dalam kategori layak. Sedangkan hasil penilaian siswa terhadap LKPD pada uji coba kelompok kecil penilaian keseluruhan sebesar 82.71% dalam kategori sangat layak dan pada uji coba lapangan terbatas penilaian keseluruhan sebesar 66.65% dalam kategori layak. Adapun perolehan nilai N-gain untuk mengetahui pengaruh lembar kerja peserta didik dapat meningkatkan pemahaman konsep siswa pada uji coba kelompok kecil skor N-gain sebesar 0.59 dalam kategori sedang. Sedangkan pada uji coba lapangan terbatas memiliki skor N-gain sebesar 0.63 masuk dalam kategori sedang. Dengan demikian, alhasil pengembangan produk lembar kerja peserta didik berbasis ekosistem mangrove melalui model project based learningdapat meningkatkan pemahaman konsep siswa SMAN 1 Lembar.

Abstract

Mangrove is an ecosystem that has a wealth of macrofauna, which includes plant species and biota associated therein, gastropods and bivalves associated with mangroves as living habitat, shelter, spawning and food supply. The purpose of this study was to determine the diversity of macrofauna associated with mangrove species. This research is a quantitative descriptive research with a survey method. The results showed that the diversity of gastropods and bivalves on the gastropod Cemara beach was 2.05. Bivalvia 1.22. Meanwhile in Bagek Kembar. Gastropods 1.73 and bivalvia 1.32 have relatively low diversity. The results of the analysis using the contingency table at the study site were 8 pairs from the Gastropod class and 4 pairs from the Bivalvia class, these pairs tended to associate at the 5% test level. The macrofauna and mangrove species pairs obtained had a positive association of 6 pairs, namely (Telescopium -Avicennia lanata, Terebralia sulcata -Avicennia lanata, Cerithideacingulata-Rhizophora mucronata, Cerithidea cingulata-Avicennia marina, Cerithideacingulata-Sonneratia caseolaris, Batillaria zonalis -Rhizophora stylosa) whereas in class bivalves there are 4 pairs (Anadara antiquata -Avicennia lanata, Anadara antiquata -Ceriops decandra, Gafrarium pectinatum -Avicennia lanata, Lutraria lutraria-Rhizophora mucronata). This pair of macrofauna with mangrove species shows a close relationship between the two. For future mangrove planting, it can be used as a benchmark by looking at macrofauna and mangrove pairs that are positively associated.

Abstract

Mangrove ecosystems have an important role in coastal areas. One of the roles of mangroves is to protect the shoreline and prevent seawater intrusion. Molluscs are one of the mangrove association biota whose lives are influenced by the presence of mangrove forests. Therefore, the purpose of this study was to determine the diversity of molluscs and the relationship between mangrove density and limiting molluscs to the coastal mangrove area of ​​Gerupuk Beach, Central Lombok. Sampling of molluscs used the quadrate sampling method with purposive sampling by taking into account the mangrove species found in the observation plots. The data obtained were then analyzed with the charisma index, associations, and Pearson's correlation coefficient. The results of this study obtained 13 species of Molluscs consisting of 12 species of the Gastropod family and 1 species of the Bivalvia family. The Brachyura diversity index at the research station was moderate with a value between 1.48–1.88. Furthermore, there were 8 species of Molluscs associated with 4 species of mangrove from 13 species of Molluscs found. The linear regression equation y = 0.1429x + 0.0007 with a Pearson correlation coefficient (r) of 0.57 indicates a strong relationship between the independent variable (x) mangrove density and the dependent variable (y) exposure to molluscs. The conclusion of this study is that the diversity of molluscs in the mangrove area of ​​Gerupuk Beach is included in the moderate category and there is a significant relationship between mangrove density and mollusk attractions.

Abstract

Cedar Beach is a tourist attraction with a unique mangrove forest, opened in 2015 by the Maritime Affairs and Fisheries Service together with the South Sheet Village. Macro fauna is a group of large animals that live in the soil or water and have an important role in improving the physical, chemical and biological properties of the surrounding environment. Research on the diversity of molluscs (Gastropoda and Polecypoda) was conducted to determine the type, diversity, and relationship between Molluscs (Gastropoda and Polecypoda) and Mangrove. The number of individual Gastropods and Polecypods found in the mangrove area of the Cypress Beach is 9 species of Gastropods and 4 species of Polecypods. Diversity of Gastropods found in the mangrove area of Pantai Cemara was 1,009 in the moderate category, 0,405 in the diversity of Polecypoda was found in the low category, and mangrove diversity was categorized as moderate. The correlation between the diversity of Gastropods, Polecypoda and mangrove diversity is not significant because the environmental parameter value is salinity at the study site above 35 ppm which has a negative impact on mangroves due to negative osmotic pressure.

Abstract

Research on the population structure of Assiminea brevicula associated with mangrove vegetation in Poton Bako Bay, South Coast of East Lombok was conducted in June 2023. This study aims to determine population structure, population density, distribution patterns and the length-weight relationship of Assimineea brevicula gastropods associated with Poton Bako mangrove vegetation, South Coast of East Lombok. Data collection was carried out using the quadratic method using purposive sampling by taking into account the mangrove species found in the observation plots. As a result, the frequency of the number of Assiminea brevicula gastropods in relation to the shell length of the samples was in the size range of 6 mm - 7 mm. The maximum shell length obtained was 10 mm. From the data obtained, the highest density figure during the research was located at station 3, namely 8.24 ind/m2. The population distribution pattern of Assiminea brevicula in Poton Bako is clustered, uniform, and random with a dominant cluster pattern. The length-weight relationship on June 11 2023 obtained the equation W = 0.18L1.04 and on June 18 2023 obtained W = 0.68L0.31, and on June 25 2023 with the equation W = 0.067L1.48 because slope < 3, with a thin shape, the nature of growth is negative allometric, which means that the increase in length of the snail is faster than the increase in weight.
