ABSTRAK

Tanaman Daun Cengkeh merupakan salah satu tanaman penghasil minyak atsiri yang cukup penting sebagai komoditas ekspor Indonesia. Namun daun cengkeh cenderung dibuang karena dianggap sebagai sampah padahal dapat menghasilkan nilai lebih ekonomis. Dalam menghasilkan minyak daun cengkeh diperlukan upaya untuk memperbaiki metode dan kondisi operasi agar proses penyulingan dapat menghasilkan minyak daun cengkeh sesuai dengan standar mutu SNI. Penelitian ini bertujuan untuk mempelajari perbandingan proses pengambilan minyak daun cengkeh dengan metode hydro distillation dan steam-hydro distillation dengan pemanasan microwave serta mempelajari pengaruh faktor daya 264 dan 400 watt yang digunakan dan massa bahan baku 50 70 90 110 dan 130 gram terhadap rendemen dan mutu minyak daun cengkeh. Pada penelitian yang dilakukan digunakan pelarut air untuk mengambil minyak dalam daun cengkeh serta dilakukan pengambilan distilat setiap 15 menit. Uap yang dihasilkan dikondensasi dan distilat yang berupa campuran minyak dan air dipisahkan dengan menggunakan corong pemisah. Perolehan minyak dimurnikan dengan sodium sulfat anhidrat Na2SO4 untuk memisahkan minyak dari sisa air yang masih tertinggal. Dari hasil penelitian didapatkan hasil terbaik pada metode hydro distillation dengan pemanfaatan microwave pada daya 400 watt dan massa 90 gram dengan rendemen sebesar 28349 dan kandungan eugenol 7931. Densitas minyak daun cengkeh didapat 10420-10217 gml untuk metode hydro-distillation dan 10435-10204gml untuk metode steam-hydro distillation. Nilai indeks bias untuk metode hydro-distillation berada pada range 15331-15326 dan metode steam-hydro distillation berada pada range 15327-15312.


ABSTRACT

Clove leaves can produce essential oil which quite important for Indonesian export comodities. Unfortunately clove leaves tend to be discarded because they are considered as trashes even though they bring more economic value. In producing clove leaves oil we need to improve methods and operating conditions in order to produce a clove leaves oil which is appropriate with SNI quality standards. This research studies the comparison of extracting clove leaves oil by applying hydro distillation and steamhydro distillation with microwave as well as studies the influence of used power 264 and 400 watt and weight of clove leaves 50 70 90 110 and 130 grams to yield and quality of clove leaves oil. This research also studies the process that using water as solvent to extract oil in clove leaves with sampling the distillate in every 15 minutes. Vapor produced is condensed and the distillate that contains with the mixture of water and oil is separated by using separator funnel. The gained oil is purified by sodium sulphate anhydrate Na2SO4 to separate the oil from the water that left over. From the result of research we gain conclussion that the best result of clove leaves oil is obtained from hydro distillation by using microwave with 400 watt of the power used and 90 grams of clove leaves weight variable. This variable obtains 2.8349 yield and eugenol composition 79.31. The values of the clove leaves oil densities are 1.0420-1.0217 gml for hydro distillation and 10435-10204 gml for steam-hydro distillation. The values of the clove leaves oil refractive indexes are 1.5331-1.5326 dan metode steam-hydro distillation berada pada range 1.5327-1.5312.
