Analysis of Mangrove Vegetation in the Patuguran Mangrove Tourism Jogging Track Area, Rejoso District, Pasuruan Regency as a Potential Resource for Learning Biology 1st Grade of Senior High School Analisis Vegetasi Mangrove di Kawasan Jogging Track Wisata Mangrove Patuguran Kecamatan Rejoso Kabupaten Pasuruan sebagai Potensi Sumber Belajar Biologi Kelas X

Abstract

Mangroves are plants that live on the coast or river estuary with the influence of tidal influences of seawater. The vegetation is specially arranged in the levels of trees, stakes, poles, and seedlings. Vegetation analysis is used to study the arrangement and composition of vegetation based on plant structure. Patuguran Village, Rejoso District, Pasuruan Regency has a mangrove forest area, namely the Patuguran Mangrove Tourism Jogging Track. This study aims to determine mangrove vegetation, INP and diversity index and mangroves in the Patuguran Mangrove Tourism Jogging Track Area and find out its potential as a source of biology learning for class X. The results of this study show that there are 6 types of mangroves, namely Avicennia marina (Forssk.) Vierh., Avicennia alba Blume, Rhizophora stylosa Griff., Sonneratia caseolaris (L.) Engl., Acanthus ilicifolius L., and Bruguiera gymnorhiza (L.) Lam. ex Savigny. Avicennia marina also has the highest INP in all stands, namely at the tree level of 150.970%, the pole level of 180.819%, the pile level of 172.043% and the seedling level of 189.416%. The type of mangrove that has the highest overall important index value is Avicennia marina (Forssk.) Vierh., with a value of 167.482%. The mangrove diversity index (H') of stations I, II, and III yielded values of 0.838, 0.952, and 0.948, respectively. The total value of the diversity index is 1.057. The results of the analysis were used as a learning resource for biology class X on biodiversity materials, which were presented in the form of poster learning media
