Abstract

Indonesia adalah salah satu negara penghasil minyak atsiri terbesar di dunia. Salah satu tumbuhan yang dapat menghasilkan minyak atsiri yaitu akar wangi. Kegunaan minyak akar wangi tidak jauh dengan kegunaan minyak atsiri pada umumnya, yaitu dapat dimanfaatkan sebagai bahan baku obat-obatan dan kosmetik. Selain itu, minyak atsiri dari tanaman akar wangi juga berpotensi berperan sebagai antioksidan dan antibakteri karena mengandung senyawa terpenoid yaitu eremophilane, eudesmane, dan nootkatone. Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri minyak akar wangi terhadap Escherichia coli ATCC 25922 dan Pseudomonas aeruginosa ATCC 27853. Metode yang digunakan pada penelitian ini yaitu metode difusi sumuran untuk mengetahui diameter daya hambat dengan beberapa konsentrasi minyak akar wangi (20%, 40%, 60%, 80%, dan 100% v/v). Kontrol positif yang digunakan adalah meropenem, sedangkan kontrol negatif yang digunakan adalah n-heksana. Hasil penelitian menunjukan bahwa nilai diameter daya hambat terbesar terdapat pada konsentrasi 80% untuk  E. coli dengan nilai DDH 3,89 mm dan 20% untuk P. aeruginosa dengan nilai DDH 20,61 mm. Oleh karena itu, dapat disimpulkan bahwa pada minyak atsiri akar wangi terdapat aktivitas antibakteri terhadap E.coli dan P. aeruginosa. Kata kunci: antibakteri; diameter daya hambat; minyak atsiri akar wangi; escherichia coli; pseudomonas aeruginosa

Abstract

          Sorgum merupakan salah satu serealia sumber karbohidrat yang sering dimanfaatkan sebagai bahan baku industri khususnya dalam bentuk pati. Ekstraksi pati menghasilkan produk samping yaitu protein yang memiliki kandungan protein 3 kali lipat lebih tinggi dari kandungan protein pada biji sorgum. Isolasi protein sorgum dapat dilakukan dengan menggunakan enzim α-amilase. Sifat fisik dan kimia akan memengaruhi sifat produk selama proses pengolahan, penyimpanan dan konsumsi makanan. Sifat fisikokimia tersebut meliputi kadar air, abu, protein, lemak, dan morfologi permukaan granula isolat protein sorgum. Penelitian ini bertujuan untuk mengetahui karakteristik fisikokimia yang dimiliki oleh isolat protein sorgum yang dihasilkan. Penelitian ini dilakukan dengan metode eksperimental yang dilanjutkan dengan analisa secara deskriptif. Penelitian yang dilakukan 2 konsentrasi enzim yang berbeda (30000 U/g dan 53681,6 U/g) dalam waktu hidrolisis yang sama (30 menit). Hasil isolasi protein menggunakan metode enzimatis dengan konsentrasi enzim α-amilase 53681,6 U/g pati, menghasilkan konsentrat protein sorgum dengan kandungan protein 70,96%, serta kadar non-protein seperti kadar air, abu, lemak, dan karbohidrat dengan nilai berturut-turut sebesar 79,72%, 0,68%, 0,15%, dan 5,1% dengan morfologi isolat protein berupa kafirin yang saling menempel erat satu dengan yang lainnya mengelilingi endosperm.           Sorghum is a cereal source of carbohydrates that is often used as industrial material, especially in the form of starch. Extraction of starch produces protein as a by-product which has a protein content of 3 times higher than the protein content of sorghum grain. Isolation of sorghum protein can be done by using the α-amylase enzyme. The physical and chemical properties will affect the product properties during the processing, storage, and consumption of food. The physicochemical properties included water content, ash, protein, fat, and surface morphology of sorghum protein isolate granules. This study aims to determine the physicochemical characteristics of the sorghum protein isolate produced. This research was conducted using an experimental method followed by a descriptive analysis. The experiment was conducted with 2 different enzyme concentrations (30000 U/g and 53681.6 U/g) in the same hydrolysis time (30 minutes). The results of protein isolation using the enzymatic method with α-amylase enzyme concentration of 53681.6 U/g starch, resulted in a protein concentrate of sorghum with a protein content of 70.96%, as well as non-protein content such as water, ash, fat, and carbohydrate content which their values are 79.72%, 0.68%, 0.15%, and 5.1% respectively with the morphology of protein isolates in the form of kafirin which are closely attached to one another around the endosperm

Abstract

Minyak nilam yang dihasilkan oleh petani umumnya masih memiliki kualitas yang rendah dikarenakan teknik penanganan panen dan pascapanen yang kurang tepat. Beberapa penelitian telah dilakukan untuk meningkatkan mutu minyak nilam dengan menggunakan metode distilasi fraksinasi. Distilasi fraksinasi merupakan proses pemisahan komponen berdasarkan titik didih senyawa. Penelitian ini bertujuan untuk mengetahui pengaruh rasio refluks terhadap kondisi proses distilasi fraksinasi. Metode penelitian yang digunakan adalah metode eksperimen dengan analisis deskriptif. Penelitian ini dilakukan dengan menggunakan tiga variabel, yaitu rasio refluks 20:1, 30:1 dan 40:1 dengan pengulangan sebanyak dua kali, serta diatur untuk menghasilkan 5 fraksi (cut) pada masing variabel. Parameter yang diukur meliputi bobot jenis, indeks bias, rendemen proses, massa residu, massa hilang dan total lama waktu distilasi. Hasil penelitian menunjukkan perlakuan refluks memberikan pengaruh terhadap kondisi operasi dimana semakin besar rasio refluks yang digunakan maka waktu yang dibutuhkan untuk distilasi fraksinasi juga semakin lama. Kondisi operasi optimal diperoleh pada rasio refluks 20:1. Perolehan lama waktu dan rendemen proses secara berturut adalah 10,9 jam dan 93%. Rasio refluks 20:1 dinilai lebih efisien karena waktu fraksinasi yang lebih singkat serta mampu menghasilkan rendemen yang tinggi.
