Abstract

Minyak atsiri serai (Cymbopogon citratus) dapur telah dipergunakan secara luas di berbagai industri, diantaranya sebagai agen antibakteri. Pada penelitian ini dievaluasi aktivitas antibakteri dan toksisitas minyak serai dapur yang dipekatkan pada suhu berbeda. Toksisitas dievaluasi melalui uji brine shrimp lethality test (BSLT), sementara uji antibakteri dilakukan terhadap bakteri Staphylococcus aureus dan S. epidermidis dengan metode difusi dan dilusi. Komponen kimia yang terdapat dalam minyak serai dianalisis menggunakan kromatografi gas spektrometri massa (GC-MS). Hasil yang diperoleh menunjukkan berdasarkan uji BSLT diperoleh nilai lethal concentration 50 (LC50) sampel minyak serai dapur semua perlakuan < 1000 ppm dengan LC50 terendah sebesar 16,53 ± 2,82 ppm. Nilai konsentrasi hambat minimun (KHM) dan konsentrasi bunuh minimum (KBM) minyak serai dapur terhadap S. aureus umumnya lebih rendah dibanding terhadap S. epidermidis. Aktivitas antibakteri minyak serai dapur terhadap S. aureus terkategori sangat kuat dengan nilai KHM dan KBM terendah ditunjukkan oleh minyak serai tanpa perlakuan pemekatan yaitu sebesar 1250 dan 2500 ppm terhadap S. aureus. Komposisi senyawa kimia utama dalam minyak serai dapur berdasarkan analisis GC-MS ialah sitral, neral dan β-myrcenehttp://dx.doi.org/10.23960/aec.v6.i2.2021.p168-179

Abstract

This study aims to analyze the influence of determinants that influence the distribution of pawn financing (Rahn) at PT. Indonesian Sharia Pawnshop for the 2017-2021 Period. The data used is quarterly data for each variable. The method used in this research is the multiple linear regression method using the Ordinary Least Square (OLS) analysis tool through the Eviews 9 program. The research results obtained are a) From the t test, the results show that partially the variables Number of Customers and Gold Price have a significant influence towards the Distribution of Pawn Financing (Rahn). Meanwhile, the Inflation Rate variable does not have a significant influence on the Distribution of Pawn Financing (Rahn); b) From the results of the f test, it was found that simultaneously the variables Number of Customers, Inflation Level and Gold Prices had a significant influence on the Distribution of Pawn Financing (Rahn); c) From the Adjusted R2 test, the results show that the variables Number of Customers, Inflation Level and Gold Price have an influence of 95.1% on the Distribution of Pawn Financing (Rahn)
