Abstract

Hortaea werneckii is a fungus causes of tinea nigra. Plants that are known to have antifungal compounds are bay leaves (Syzygium polyanthum). This study was aimed to determine the best concentration of the methanol extract from bay leaves (S. polyanthum) can inhibit the growth of Hortaea werneckii (T1) in vitro. This study used a completely randomized design (CRD) with treatment levels that consisted of concentrations of 20, 25, 30, 35 and 40%, negative control (sterile distilled water) and positive control (ketoconazole 2%). The antifungal activity test was carried out using the Kirby-Bauer method. Based on the results study showed that concentration 30% is the best concentration in inhibit fungal growth Hortaea werneckii (T1).

Abstract

Penelitian ini bertujuan untuk mengetahui apakah terdapat perbedaan kemampuan mahasiswa calon guru matematika dalam mengubah soal cerita ke dalam bentuk model matematika ditinjau dari tipe kepribadian Hipporcrates. Kemampuan representasi matematika diukur dari empat indikator yaitu representasi gambar, representasi visual, representasi kata dan representasi ekspresi matematik. Penelitian ini merupakan penelitian kualitatif yang menggunakan tiga instumen yaitu instrument angket untuk mengetahui tipe kepribadian subjek penelitian, instumen tes kemampuan mengubah soal cerita kedalam bentuk model matematika materi geometri bidang dan ruang dan instrument wawancara sebagai penguatan hasil instrument tes agar data yang diperoleh semakin valid. Data yang telah dikumpulkan kemudian dianalisis dengan menggunakan aplikasi Nvivo 12 Plu. Hasil penelitian menunjukkan bahwa keempat tipe kepribadian hipporcrates yang paling baik dalam mengubah soal cerita kedalam bentuk matematika yaitu tipe kepribadian melankolis karena dapat mengubah wacana menjadi bentuk ilustrasi, dapat menggambarkan dan menemukan segitiga kongruen dan sebangun, dapat menuliskan dan menjelaskan langkah-langkah penyelesaian suatu masalah, dan menyelesaikan permasalahan menggunakan ekspresi matematika. Hal ini menunjukkan bahwa subjek memiliki pengetahuan matematika yang utuh, baik secara konseptual maupun procedural.

Abstract

Preschool students are vulnerable to dental health problems and poor dental hygiene behavior. Dental health issues in children can have an impact on their growth, development, and learning. Therefore, it is necessary to pay attention and provide intensive methods of health services to preschool students, namely by providing dental health services directly in schools through the school's dental health business program. The method of implementing this community service activity is the provision of dental health services for school students, assisted by the Kendari City Pembina State Kindergarten. Activities carried out from September to December 2017, the activities carried out are limited to promotive, preventive, and curative services. The results of the activity showed that students' knowledge about dental health increased, changes in dental health maintenance behavior became better, and limited curative treatment could be carried out well. It is recommended that these activities be carried out continuously, in stages, and the forms of activities developed to provide greater and long-term benefits.
