“…The higher power makes microwave energy emitted larger so that it makes the degradation of the material and oil components. Tremendous energy received by the material to be converted into heat so that the reaction cuts the triglyceride compound ester bonds (TG) from the oil nyamplung will be bigger, making the TG turn into FFA so FFA increases ( Erliyanti and Rosyidah, 2017 ).…”

“…Hasil dari kandungan senyawa metabolit sekunder yang dimanfaatkan pada kulit bawang merah dipengaruhi oleh metode ekstraksi dan pelarut yang digunakan (Sulistiyono et al, 2018). Beberapa metode ekstraksi yang dapat digunakan untuk menghasilkan senyawa metabolit sekunder adalah Microwave Assisted Extraction (MAE) (Sulistiyono et al, 2018), metode microwave hydrodistillation (Erliyanti dan Rosyidah, 2017), metode sokletasi (Widodo et al, 2019), metode maserasi (Puspitasari dan Proyogo, 2017). Berdasarkan metode tersebut yang paling mudah adalah metode maserasi karena prosedur dan peralatan yang digunakan sederhana dan tidak dipanaskan sehingga bahan alam tidak terurai (Puspitasari dan Proyogo, 2017).…”

Bawang merah diambil bagian umbi, untuk bagian kulit bawang merah penggunaanya masih terbatas. Kulit bawang merah (Allium cepa L.) merupakan limbah yang belum dimanfaatkan. Tujuan Penelitian ini untuk mengetahui pelarut antara ekstrak etanol 96%, ekstrak air, ekstrak campuran etanol 96%-air menghasilkan ekstrak kulit bawang merah (Allium cepa L.) paling tinggi dan mengetahui perbedaan kandungan golongan senyawa kimia dari ekstrak etanol 96%, ekstrak air, ekstrak campuran etanol 96% dan air pada kulit bawang merah (Allium cepa L.). Penelitian dilakukan secara eksperimen, sampel di ekstraksi dengan cara di maserasi selama 3 X 24 jam dengan menggunakan pelarut etanol 96%, pelarut air dan pelarut campuran etanol-air. Hasil rata-rata rendemen ekstrak etanol 96% 10,66%, ekstrak air 10,29% dan ekstrak campuran etanol-air 13,27%. Berdasarkan hasil penelitian bahwa rendemen optimal pada ekstraksi kulit bahwa merah menggunakan pelarut campuran etanol-air yaitu sebesar 13,27% dengan analisis fitokimia secara kualitatif mengandung senyawa alkaloid, flavonoid, saponin. Kata Kunci : Ekstrak Kulit Bawang Merah, maserasi, pelarut

“…Sumber daya alam hayati yang dimiliki oleh Indonesia sangat banyak, beragam, dan belum banyak dimanfaatkan secara optimal. Salah satu keanekaragaman sumber daya alam hayati tersebut terdapat tanaman yang berpotensi untuk dijadikan minyak atsiri [1]. Sekitar 40 -50 jenis tanaman yang berpotensi menghasilkan minyak atsiri dan diperdagangkan di seluruh dunia ditanam di Indonesia [2].…”

“…Hal ini dikarenakan aquadest mempunyai konstanta dielektrik yang tinggi [16]. Konstanta dielektrik adalah suatu ukuran yang menunjukkan kemampuan pelarut untuk menyerap gelombang mikro [1]. Pelarut yang mempunyai konstanta dielektrik yang tinggi mempunyai kapasitas yang tinggi untuk menyerap energi microwave [17].…”

Crystal seedless guava is a new horticultural commodity that is cultivated in Indonesia and has many benefits. Crystal seedless guava has the potential of essential oil to be extracted from the leaves. Extraction using the microwave hydrodistillation method is an alternative to improve the efficiency and effectiveness of the essential oil extraction process. The purpose of this study was to determine the effect of microwave power and the feed to solvent ratio toward the characteristics of density and refractive index of essential oil from crystal seedless guava leaves. The reduced size crystal seedless guava leaves were extracted by microwave using aquadest as solvents with the feed to leaves. The ratio of feed to solvents used in this study was 1:4, 1:5, 1:6, and 1:7 (weight/volume or w/v). The second variables were performed using various microwave powers of 300, 450, and 600 Watts. The extraction conditions were carried out at ± 100 o C at one atmospheric pressure for three hours. The results showed that microwave powers and material to solvent ratios had significantly effect toward the density of essential oil from crystal seedless guava leaves. However, the variables had no significant difference in the value of the refractive index. The higher number of microwave powers and the solvent to feed ratios had a higher number of density. The highest density and refractive indexes were 0.948 grams/ml and 1,49862, respectively. The best extraction condition to extract the essential oil from crystal seedless guava leaves using microwave hydrodistillation was performed by microwave power of 600 Watt with 1:7 (w:v) as leaves to solvent ratio.
