Abstract

Clove essential oil is processed product of clove leaves which is used as perfumes and medicines. In general, the method used to extract clove leaf essential oil is the steam distillation method. This method has not maximized the yield essential oils produced because a lot of essential oils are still trapped in plant tissues. Modification of the essential oil isolation methods to produce more yields needs to be done, one of which is the fermentation method with the help Rhizopus oligosporus before the distillation process is carried out. The fermentation method is able to destroy the oil tissues on the leaves using enzymes produced by rhizopus oligosporus. The aims of this study were to isolate the essential oil clove leaves and look for the effect of the mass and fermentation time on the yield and content of clove leaf essential oil compounds produced. The results showed that the isolation  essential oils using fermentation methods was successfully carried out, the mass and fermentation time had a significant influence on the yield and content of essential oil chemical compounds. The best result was obtained at a mass of 35 grams with a fermentation time of 36 hours with a yield 0.32% and the content eugenol, caryopillene compounds obtained respectively at 93.43% and 2.28%.

Abstract

Industri batik tergolong industri dalam jumlah besar dan berbahaya. Salah satu limbah yang dihasilkan adalah limbah cair yang mengandung ion krom (Cr 6+). Cairan limbah yang dikeluarkan sangat keruh, berwarna, dan memiliki pengelolaan yang busuk sehingga menimbulkan masalah serius bagi badan air, masyarakat, dan lingkungan. Limbah tanpa perlakuan khusus dibuang ke lingkungan. Sehingga metode pertukaran ion dapat mengurangi pencemaran lingkungan akibat limbah industri batik. Penelitian ini bertujuan untuk mengetahui pengaruh resin dalam menurunkan kandungan ion kromium pada limbah cair industri batik dengan menggunakan metode pertukaran ion. Yaitu dengan menggunakan dua kondisi operasi yang divariasikan yaitu berat resin (40, 60, 80, 100, dan 120 gram) dan kecepatan pengadukan (150, 175, 200, 225, dan 250 rpm). Ion kromium yang bermuatan positif akan bertukar dengan H +ion yang ditemukan dalam resin dowex. Sehingga kandungan krom pada limbah cair batik dapat dikurangi. Hasil tersebut diperoleh dari kecepatan pengadukan dan berat resin yang digunakan. Penurunan kandungan ion chromium tertinggi terjadi pada kecepatan pengaduk 250 rpm dengan berat resin 120 gram sebesar 97,86%.

Abstract

The essential oil from crystal seedless guava leaves has several utilization as an antioxidant and antimicrobial active compound. Essential oil extraction with maceration and conventional method has many disadvantages, so the microwave hydrodistillation method is used as an alternative to optimizing its quantity and quality. This research aims to obtain the effect of microwave power and feed to the solvent ratio toward essential oil yield. The extraction of essential oil used crystal guava leaves with feed and solvent ratio (w/v) 1:4; 1:5; 1:6; 1:7. The extraction process was carried out at atmospheric pressure and 100 oC with an electrical power of microwave from 300, 450, and 600 watts over 3 hours. The result shows that microwave power and the ratio of feed to solvent (F/S) give a significant ratio to essential oil yield. Its yield rises significantly along with increasing microwave power and ratio of feed and solvent. The highest yield is obtained at 600 watts and 1:7 (w/v) ratio that is 1.0 %.
