Abstract

ABSTRAKTujuan dari penelitian ini adalah untuk mengetahui diameter daya hambat air rebusan daun sirih terhadap bakteri penyebab mastitis. Bakteri yang digunakan dalam penelitian ini adalah Staphylococcus aureus dan Escherichia coli. daun sirih yang digunakan adalah daun sirih hijau yang banyak tumbuh di Pulau Timor. Rancangan penelitian yang digunakan adalah faktorial dengan 3 waktu perebusan (30, 45 dan 60 menit) dan 3 konsentrasi (12.5%, 25% dan 50%) dengan 3 pengulangan. Hasil penelitian menunjukkan bahwa air rebusan daun sirih hijau belum mampu menghambat pertumbuhan bakteri Escherichia coli. Air rebusan daun sirih konsentrasi 50% dengan waktu perebusan 45 menit menunjukkan hasil penghambatan paling besar. Air rebusan daun sirih mampu menghambat bakteri Staphylococcus aureus namun belum mampu menghambat bakteri Escherichia coli.Kata kunci: Escherichia coli, rebusan air daun sirih, Staphylococcus aureus, uji antibakteriABSTRACTThe aim of this study is to determine the inhibition of betel leaf decoction water against bacteria that caused mastitis. The bacteria used in this study are Staphylococcus aureus and Escherichia coli. The betel leaves used are non-fragrant green betel leaves which are widely grown on Timor Island. The design used was a factorial pattern with 3 boiling time (30, 45 and 60 minutes) and 3 concentrations of boiled water (12.5%, 25% and 50%) with 3 replications. The results showed that the betel leaf decoction water was not able to inhibit the growth of Escherichia coli. Betel leaf decoction water concentration of 50% with a boiling time of 45 minutes showed the greatest inhibitory effect. Betel leaf decoction water has been proven to be able to inhibit the Staphylococcus aureus but has not been able to inhibit Escherichia coli.Keywords: Escherichia coli, decoction of betel leaf water, Staphylococcus aureus, antibacterial test

Devotion with the title of potential plant extracts as natural pesticides in Salu village, Miomafo Barat district, TTU district was held in November 2018. The purpose of this service was to provide knowledge on how to increase food production through eradicating pests, providing knowledge about the advantages of natural pesticides compared to synthetic pesticides, and make soursop leaf extract as a natural pesticide. The main target of this activity is the farmers who are conducted through methods of lecture, brochure distribution, and product manufacturing training. This service activity was conducted in 3 sessions. The first session was socialization of ways to increase food production through eradicating pests. The second session is a socialization of the advantages of natural pesticides compared to synthetic pesticides. Making soursop extract as a natural pesticide is the third session that closes all the series of devotion. In addition to providing questions, farmers also provide personal experiences that are useful for the development of science. The coordination of the making of soursop extract indicates the high enthusiasm of the farmers in Salu village towards this devotion. The final product in this activity is soursop leaf extract which is ready to be applied to plants.

Abstract

Processing and application of tarum leaves into indigo powder for woven threads dyeing has been carried out in the Weaver Women's Group of Amol Village, North Central Timor District. The less knowledge in producing indigo-colored woven fabrics and unavailable source of Indigo leaves during the dry season are the main reasons to conduct this program. This program was carried out in 4 main stages, namely socialization, demonstration of Indigo leaves processing into indigo powder, application in yarn dyeing and evaluation. This activity was able to increase the knowledge and skills of the Weaver group in processing Indigo leaves which are abundant in the rainy season into indigo powder which can be stored for use in the dry season. The resulted powder has been applied in the coloring of the woven yarn to produce an indigo blue color.
