Abstract

Staphylococcus aureus merupakan salah satu bakteri patogen yang bisa menyebabkan infeksi. Penggunaan antibiotika untuk penanganan infeksi yang tidak rasional dapat membuat kuman patogen menjadi resistensi, sehingga penggunaan Rimpang kunyit (Curcuma domestica V.) mungkin dapat sebagai alternatif pengganti antibiotik. Tujuan penelitian ini adalah untuk mengetahui daya hambat ekstrak etanol rimpang kunyit (Curcuma domestica V.) terhadap pertumbuhan bakteri Staphylococcus aureus secara in vitro. Penelitian ini bersifat eksperimental laboratorium dengan desain post-test only control group design menggunakan metode difusi (cakram) yang dilakukan dari Februari 2015 sampai September 2015 di Laboratorium Mikrobiologi Fakultas Kedokteran Universitas Andalas. Sampel yang digunakan adalah rimpang kunyit yang berasal dari ladang kunyit Puncak Payo, Tanah Garam Solok. Berdasarkan hasil penelitian dapat disimpulkan bahwa ekstrak etanol rimpang kunyit (Curcuma domestica V.) memiliki daya hambat yang berbeda terhadap pertumbuhan bakteri S. aureus dengan berbagai konsentrasi yaitu 10%, 20%, 40%, 80% b/v . Konsentrasi ekstrak yang paling efektif dalam menghambat S. aureus adalah konsentrasi 80% b/v. Penggunaan ekstrak etanol rimpang kunyit (Curcuma domestica V.) sebagai alternatif pengganti antibiotik terhadap infeksi oleh S. aureus perlu dipertimbangkan.

Abstract

The objectives of this study were to identify types of politeness strategies, to examine the differences of  politeness patterns used by different gender and to see how the politeness strategies imply in the culture of “indirectness” a culture of Javanese who avoid being direct to utter something which were reflected in Javanese indirect speech acts in request. The approach used in this study are based on politeness theory of Brown & Levinson (1987); Bald-on record, Positive, Negative, and Off Record. This study employed descriptive qualitative design. The data were the transcription of recorded observation and interview using audiovisual recorder in Javanese social interaction in doing business transaction  at “PasarRebo”, a traditional market in Deli Serdang, North Sumatera. The politeness strategies used were bald-on record strategy, positive politeness strategy and negative politeness strategy. Different strategies were performed by different gender; male dominantly used bald-on record strategy while female dominantly used positive politeness strategy. The realization of Javanese indirect speech acts used by female established an indirect correlation to politeness strategies and the culture of “indirectness” in Javanese. The realization of these politeness strategies by the speakers were aimed to minimize Face Threatening Acts to endeavor a harmony in social interaction. Keywords: Gender; Indirect speech act; Politeness strategiesement if they were taught by using TBL model.

Abstract

Proverbs are words or groups of words which states a purpose or will, circumstance of someone, something, or something that express behavior, actions and things about a person indirectly, but implicitly convey a message that can be understood by both the reader and the listener. String matching is an algorithm to search for all occurrences of short and long strings, and for short strings called patterns and long strings called text. Horspool Algorithm is a simplification of the Boyer-Moore algorithm which in search of text is to search in large text to find the first pattern. Because the text sought can be very large (allowing hundreds of thousands of characters) it is important to use more efficient techniques based on that case, a search application based on android is made to make it easier for someone to find proverbs because not everyone understands this and that makes it more practical and efficient in terms of its use without having to carry proverbs in print media such as books.
