Abstract

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 oC 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.

Abstract

Karbon aktif adalah karbon yang diproses sedemikian rupa sehingga mempunyai daya serap/adsorpsi yang tinggi terhadap bahan yang berbentuk larutan atau uap. Karbon aktif dapat dibuat dari bahan yang mengandung karbon baik organik atau anorganik, tetapi yang biasa beredar di pasaran berasal dari tempurung kelapa, kayu dan batubara. Karbon aktif dapat dipergunakan untuk berbagai industri, antara lain yaitu industri obat-obatan, makanan, minuman, pengolahan air (penjernihan air) dan lain-lain. Hampir 70% produk karbon aktif digunakan untuk pemurnian dalam sektor minyak kelapa, farmasi dan kimia. Banyak industri yang membutuhkan karbon aktif sebagai bahan pembantu atau bahan penunjang dalam proses, sehingga pabrik karbon aktif ini sangat potensial untuk didirikan baik untuk memenuhi kebutuhan industri dalam negeri dikarenakan kebutuhan karbon aktif setiap tahun meningkat. Pada tahun 2018 kebutuhan akan karbon aktif mencapai 11860,851 ton. Melihat banyaknya kebutuhan karbon aktif didalam negeri maka direncanakan pendirian pabrik karbon aktif di Indonesia. Pabrik karbon aktif direncanakan didirikan pada tahun 2022 yang berlokasi di kawasan industri Kota Dumai – Riau dengan kapasitas produksi sebesar 20000 ton/tahun. Proses yang digunakan pada pembuatan karbon aktif adalah menggunakan proses pembakaran (pirolisis) dan proses aktivasi secara kimia. proses pembuatan karbon aktif harus melalui 4 tahap, yaitu tahap pre-treatment, pirolisis, aktivasi, dan penyelesaian. Berdasarkan analisa ekonomi yang telah dilakukan diperoleh internal rate of return sebesar 10.82 % dengan pay out time selama 4,11 tahun dan break even point sebesar 32%. Ditinjau dari uraian di atas, maka secara teknis dan ekonomis, pabrik karbon aktif dari tempurung kelapa layak untuk didirikan
