Penelitian ini bertujuan untuk mengetahui jenis-jenis tumbuhan paku terestrial yang ada di KHDTK (Kawasan Hutan dengan Tujuan Khusus), besarnya frekuensi dan frekuensi relatif tumbuhan paku terestrial, dominansi dan dominansi relatif tumbuhan paku terestrial, indeks nilai penting daritumbuhan pakuterestrial, dan indeks dominansitumbuhan paku terestrial. Metode penelitian yang digunakan adalah metode deskriptif dengan teknik purposive samplingdengan melihat komposisi jenis dan jumlah tumbuhan paku pada suatu area tertentu. Penelitian ini digunakan untuk mendeskripsikan keanekaragaman jenis paku yang ada di KHDTK (Kawasan Hutan Dengan Tujuan Khusus), Pandeglang, Banten. Pengamatan terhadap kondisi lingkungan meliputi intensitas cahaya, suhu lingkungan, kelembaban lingkungan, pH tanah, dan ketinggian tempat. Hasil penelitian yang diperoleh adalah ditemukannya tiga spesies pakupada KHDTK, yaitu Selaginella plana, Lygodium salicifolium,danDiplazium esculentum.INP tertinggi terdapat pada spesies Selaginella planadan terendah terdapat pada Diplazium esculentum.Selaginella planalebih dominan dibandingkan spesies lainnya yaitu Lygodium salicifolium danDiplazium esculentum.
This research aims to find out the relationship between critical thinking skills and students’ learning motivation in the excretory system content. The research employs a descriptive method with correlation approach. The research population includes students of Madrasah Tsanawiyah Negeri of a school in Jakarta Timur, Indonesia. Sampling is conducted using multi-stage sampling. Samples used are 95 students of Grade IX. The research instruments consist of critical thinking skill test and learning motivation questionnaire. Data analysis uses regression analysis technique. The regression equation is compiled and tested with variance analysis using ANOVA table with F-test. The multiple regression hypothesis testing carries out by compiling multiple regression equation and testing using variance analysis with t-test. The research results indicate pxy, means that there is a correlation between critical thinking and learning motivation. The research recommendation is that the excretory system learning activity empowers critical thinking so that it improves motivation to learn the excretory system.
