Abstract

Tanaman obat tradisional merupakan potensi teknik pengobatan yang diketahui lebih aman dan murah. Pengembangan kajian ilmiah tanaman obat mendorong dilakukannya penelitian terhadap potensi tanaman sebagai antimikroba. Salah satu tanaman obat yang berkhasiat adalah Delima Merah (Punica granatum). Untuk mengetahui kemampuan antimikroba Punica granatum, maka dilakukan penelitian dengan memakai ekstrak etanol daun Punica granatum yang dibuat kedalam seri konsentrasi yang bervariasi dari terkecil hingga terbesar. Mikroba patogen yang digunakan berjumlah delapan mikroba patogen dengan masing-masing tiga kali ulangan. Hasil menunjukkan bahwa jumlah konsentrasi berpengaruh terhadap zona hambat yang terbentuk untuk masing-masing mikroba uji. Dapat dismpulkan bahwa semakin tinggi konsentrasi ekstrak etanol daun delima merah maka semakin tinggi zona hambat yang terbentuk.

Abstract

Learning mathematics in elementary school is often labeled as a difficult and scary subject by students. This assumption can lead to suggestions to students that this subject is difficult to learn. This research aims to overcome the problem of difficulties in understanding and remembering mathematical formulas at SDN 101774 Up, especially in high classes by using a fun learning method, namely HARUMPALA (Memorizing Formulas Using Songs). This approach converts mathematical formulas into familiar children's song lyrics, making it easier for students to remember and understand the formulas. This research uses a qualitative approach with interview methods and literature review to gain an in-depth understanding of the factors that cause difficulties in learning mathematics at SDN 101774 Till. The research results show that the HARUMPALA method is effective in reducing mathematics anxiety and increasing students' ability to remember formulas. With a more enjoyable learning atmosphere, it is easier for students to understand and apply mathematical concepts in more depth. This method not only helps in memorizing formulas, but also in understanding the concept and its application.
