Abstract

Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri ekstrak etanol daun sirih hijau (Piper betle L.) terhadap Escherichia coli dan Staphylococcus aureus serta menentukan konsentrasi yang paling efektif dalam menghambat pertumbuhannya. Metode penelitian menggunakan difusi cakram dengan variasi konsentrasi ekstrak 40%, 60%, 80%, dan 100%, serta kontrol positif dan negatif. Hasil uji menunjukkan bahwa ekstrak etanol daun sirih hijau memiliki aktivitas antibakteri terhadap kedua bakteri uji. Konsentrasi 60% paling efektif menghambat pertumbuhan E. coli dengan kategori kuat, sedangkan konsentrasi 100% paling efektif menghambat pertumbuhan S. aureus dengan kategori sedang. Uji statistik ANOVA menunjukkan adanya perbedaan signifikan antar perlakuan (p = 0,000). Analisis GC-MS juga mengidentifikasi senyawa aktif seperti hydroxychavicol, palmitic acid, dan phytol yang berperan dalam aktivitas antibakteri. Dengan demikian, ekstrak etanol daun sirih hijau berpotensi sebagai sumber antibakteri alami yang efektif dalam menghambat pertumbuhan bakteri patogen

Abstract

Traditional medicinal plants have long been used and trusted by the community to treat various diseases. The senggani plant is useful for reducing fever (antispiretic), pain reliever (analgesic), urine laxative (diuretic), treating vaginal discharge (leukorrhea), and as a medicine for various types of wounds. This research was conducted using extracts of Melastoma malabatricum (L.) leaves extracted using methanol as a solvent. GC-MS analysis of secondary metabolites of senggani leaves (Melastoma malabatrichum L.) was carried out as a first step to determine the content of active secondary metabolite compounds contained in senggani leaves.The results of this study show that 8 peaks were observed during maximum run time of 40 min. The results revealed that, compounds such as 3-Hexadecyloxycarbonyl-5-(2-hydroxyethyl)-4-methylimidazolium, Melezitose, Thiosulfuric acid, Neophytadiene, 9-Icosyne, Phytol, Hexadecanoic acid dan 9-Octadecenoic acid (Z) were present in the methanolic extract of Melastoma malabatrichum (L.) which can mostly contribute to several therapeutic activities such as antimicrobial.

Abstract

The high rate of divorce that occurs in society is caused by several factors, including; due to disharmony, no responsibility, and economic problems. Among divorce cases, the most filed for divorce are from the wife. There are several reasons for divorce regulated by Islamic Law, Marriage Law Number 1 of 1974 in conjunction with Law Number 9 of 1975, and the Compilation of Islamic Law, including, disputes and quarrels that occur continuously as reasons for divorce. However, Islamic Law, Marriage Law Number 1 of 1974 in conjunction with Government Regulation Number 9 of 1975, and the Compilation of Islamic Law, do not explicitly stipulate in detail the minimum time limit for marriage to be able to file for divorce for this reason, and there is no explanation any reason belongs to the constant strife and bickering. This causes multiple interpretations, because the scope is too broad, so many things are used as reasons for disputes and fights for divorce, and later it can become one of the drivers of divorce which is too easy to do in people's lives. The Marriage Law cannot determine a minimum time limit for disputes and continuous bickering as reasons for divorce, because divorce is a human right.
