Using the fuel oil is the basic necessary in the world now. But, the raw material cannot be updated. To ensure the availability of the fuel oil so, the newest of alternative energy is explored it. One of the ways is biodiesel which made from vegetable oil. In this research is resulted from the transesterification reaction between candlenut oil and methanol by utilizing ultrasonic equipment. This research has passed some phases, they are the determining of acid number in oil then continued by creating biodiesel from ultrasonic wave 47 kHz. Identification of FTIR and GCMS are two methods which used to analyze the component compound in biodiesel product. The conversion number that be gotten from FAME with reaction of variation time 30, 40 and 50 in succession 0,037%, 0,029% and 0,018%. The result analysis of FTIR shows some of functional groups which are special from biodiesel. While the result of GCMS analysis is known that there are 5 component compounds in biodiesel namely ester methyl palmitic acid, ester methyl olead, stearata ester methyl, linoleic ester methyl and elaidic ester methyl.

Plants gotu kola (Centella Asiatica L .Urban) is a wild plant that efficacious as remedies traditional cure disease tuberculosis (TB).TB is disease contagious infection caused by bacteria mycobacterium tuberculosis. Research aims to understand the ability extract methanol leaves gotu kola red and leaves gotu kola green and determines the concentration optimal extract methanol leaves gotu kola red and leaves gotu kola green and to know the comparison between extract methanol leaves gotu kola red with an extract methanol leaves gotu kola green in inhibits the activity of mycobacterium tuberculosis.Extraction done with the methods maceration use methanol and continued with evaporation until obtained extract viscous .Testing antibacterial activity done in a microscopic observation drug susceptibility ( mods ) use plate petri dish 24 hole with the variation of concentration ie 20%,40%, 60%, 80% and 100%.The results of testing show that extracts methanol leaves gotu kola red and leaves gotu kola green positive capable of inhibiting the growth of bacteria mycobacterium tuberculosis with inhibition optimal in concentration 80 % and 100 % characterized by the absence of growth bacteria colonies which are (-) or 0 %.Extract methanol leaves gotu kola green capable of inhibiting the growth of bacteria mycobacterium tuberculosis better than extract methanol leaves gotu kola red seen in concentration 40% and 60%.

Isolation and identification of secondary metabolites from EtOac extract of the root bark of Kleinhovia hospita Linn. plant had been performed. Separation techniques used consisted of extraction, fractionation, and purification. The compounds obtained were tested and elucidated based on UV, IR, and NMR spectroscopy data. A compound obtained was geranil-1”,3”-dioxo-para-chresol.

SENYAWA GOLONGAN STEROID DARI EKSTRAK n-HEKSANA KULIT BATANG KAYU BITTI (Vitex cofassus) DAN UJI TOKSISITAS TERHADAP Artemia salina Leach. Asriani Ilyas; Iin Novianty; Irmayanti Irmayanti
Chimica et Natura Acta Vol 3, No 3 (2015)
Publisher : Departemen Kimia

Penelitian telah dilakukan untuk mengidentifikasi dan mengkarakterisasi senyawa bioaktif dari kulit batang kayu bitti (Vitex cofassus), suatu tumbuhan endemik dari Sulawesi yang termasuk famili Verbenaceae. Tahapan penelitian meliputi maserasi, fraksinasi, pemurnian, identifikasi dan uji toksisitas. Ekstraksi dilakukan dengan metode maserasi menggunakan n-hexane. Tahapan identifikasi meliputi melibatkan uji warna,analisis KLT, analisis IR, sedangkan uji toksisitas menggunakan metode BSLT dengan Artemia salina Leach sebagai bioindikator. Hasil penelitian adalah senyawa dengan bentuk kristal jarum berwarna putih dengan 0,4745 gram dan analisis fitokimia menunjukkan bahwa senyawa tersebut adalah senyawa golongan steroid. Hal ini juga didukung oleh data IR yang menunjukkan gugus fungsi kelompok steroid. Uji toksisitas menunjukkan harga LC50 pada ekstrak, fraksi, dan senyawa murni berturut-turut sebesar 74,079 ug/ml, 118,850 ug/ml and 88,201 ug/ml. Data ini menunjukkan bahwa seyawa murni yang dihasilkan adalah murni.
