Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak daunkenari (Canarium indicum L.) terhadap jumlah kelenjar dan ketebalan endometrium tikus putihbetina (Rattus norvegilus, L.). Jenis penelitian ini adalah eksperimen menggunakan desain penelitian Rancangan Acak Lengkap (RAL). Obyek yang digunakan adalah tikus putih yang kurang lebih2 bulan yang belum pernah bunting. Tikus dibagi menjadi 4 kelompok, yaitu kontrol (tanpa ekstrak daun kenari), perlakuan I (200 mg/ekor/hari), perlakuan II (300 mg/ekor/hari), perlakuan III (400 mg/ekor/hari). Pencekokan dengan perlakuan ekstrak daun kenari terhadap tikus putih berlangsung selama 21 hari. Data yang diamati adalah tebal lapisan endometrium dan jumlah kelenjar endometrium.Uji Kruskal Wallis digunakan untuk menganalisis  pengaruh pemberian ekstrak kenari terhadap jumlah kelenjar endometrium.Uji One Way Annova digunakan untuk menganalisis pengaruh pemberian ekstrak daun kenari terhadap tebal lapisan endometrium untuk mengetahui perbedaan antara kelompok kontrol dan kelompok perlakuan, apabila ada perbedaan yang nyata maka dilanjutkan dengan uji DMRT (Duncan’s Multiple Range Test) untuk mengetahui perbedaan antara perlakuan. Hasil penelitian menunjukkan bahwa pemberian ekstrak daun kenari memiliki pengaruh nyata (P 0,01) terhadap jumlah kelenjar endometriumdan ketebalan lapisan endometrium.Kata kunci: Kenari, Endometrium,Kelenjar  endometrium.

Learning mathematics is a crucial part of education. Mathematics is one of the subjects feared by students. One of the problems in the object of mathematics study is the material for X class of Senior High School. Students of grade X are undergoing adaptation from the junior high school level to the high school level so that the findings of conceptual errors, calculations, and thinking patterns in problem-solving algorithms are often found. This also happened to the students of the Muhammadiyah Senior High School Special Program of Kottabarat Surakarta. In connection with the above problems, the author analyzes student errors in solving math problems at the Muhammadiyah senior high school special program of Kottabarat Surakarta.This study aims to find out errors, causes of error, and alternative problem solving related to students' errors in solving math problems. This research is qualitative descriptive research. The research subjects were taken by sampling purposes.  they are three students of class X. The research method used is qualitative research methods, data collection techniques used in this study are test methods, interview methods, and documentation methods. The research instrument is the main instrument, namely the researcher himself and the auxiliary instruments in the form of test sheets, interview guidelines, and field notes. The data analysis technique uses data reduction, data presentation, and data verification, and triangulation techniques. The results of this study indicate that the types of errors that did most often made are errors in understanding questions that were 9 times, process skills errors and coding errors were 6 times, and reading errors were never made by research subjects.
