Abstract

Skopoletin merupakan senyawa kumarin yang telah dibuktikan secara ilmiah mempunyai efek kesehatan terhadap manusia.  Efek kesehatan skopoletin diantaranya adalah sebagai antikanker, antioksidan, antidiabetes tipe 2, antihipertensi, antibakteri, memperbaiki memori atau daya ingat, dan pengendalian stres serta bad mood.  Berdasarkan hal tersebut, penting untuk mengetahui sumber pangan yang mengandung skopoletin.  Penelitian ini bertujuan untuk menentukan kandungan skopoletin dalam berbagai jenis umbi-umbian yang ada di Indonesia.  Metode analisis skopoletin yang digunakan adalah metode kromatografi cair kinerja tinggi-fluoresensi (KCKT-FL).  Hasil analisis menunjukkan bahwa skopoletin terdapat pada kulit dan daging ubi kayu, ubi jalar, dan ganyong.  Skopoletin tidak terdapat pada talas, garut, dan iles-iles.  Kandungan skopoletin tertinggi terdapat pada daging ubi kayu jenis Malang 4 yaitu sebesar 112.66 mg/kg (berat kering) sedangkan pada ubi jalar terdapat pada kulit ubi jalar Cilembu sebesar 69.73 mg/kg (berat kering).

Abstract

Lactic acid bacteria (LAB) are known to have an antagonistic activity toward a variety of microorganisms Bacteriocin production from LAB is one of the properties responsible for the antibacterial activity against closely related species and possibly gram-positive food spoilers and pathogens bcteriocins produced by lactic acid bacteria are either small thermostable peptides or large thermolabile proteins .large numbers of bacteriocin producers have been found among different genera of the lactic acid bacteria .the diffusion method of bacteriocins on solid medium or antagonistic method as direct method and sport on the lawn and flip streak methods as indirect method can be used as screening of bacteriocin purification methods of bacteriocins can used ammonium sulphate precipitation ,ion exchange chromatography,hydrophobic interaction chromatography, and phase back high performance liquid chromatography. Bacteriocins are of interest for potential application in the food industry because of their antimicrobial activity and technologically favorable properties.

Abstract

The studies Ginger (zingiber officinale) is one of herb plant which contains various of active compounds,which is proved has function has  to human health .in indonesia , there are 3 main ginger variaties,those are :giant gingger (zingiber officinale var .officinale),emprit ginger (Zingiber officinale var. amarum ), and red ginger (Zingiber officinale var.rubrum) .Each ofthem has different characteristic and function .the problems which often occurs are ginger counterfeting,often mixed with other gingers.this counterfeiting difficult to be detected with conventional test method. therefore needed study about characteristic of each ginger with HPLC so counterfeiting able to be traced .Asensitive and accurate high-performance liquid chromatography (HPLC) method has been developed to determine the quantity of active componen in the methanolic extract of Zingiber officinale Bioactive component was separated on persuit C18 Column (250 mm x4.6 mm,particle size:5 um)with gradient system of water and acetonitrile as mobile phase. the calibration plot was linear in the range of 0.10-150 mg/L .of 6-,8-,10-gingerol and the correlation coefficient of o.9998 was indicative of good linear dependence of peak area on concentration .the limit of detection (LOD) OF 6-gingerol ,8-ginggerol ,6-shogaol and  6-shogaol and the correlation coefficient were 2,34 1,06; 1,25, and 0,67 mg/l and limit of detection (LOD)were 7,81 :3,53 :3,53; 4,18 and 2,29 mg/lrespectively.the developed HPLC method was found selective,precise and accurate,and can be used for routine analysis of gingers in the quality control laboratories .

Abstract

Deodorizing and reaction time of degumming are some of the most important factors that can affect the quality refined vegetable oils or its derivatives. The results of unit operations in doedorizing and degumming give low viability of product especially produced by vegetable oils smallholder industry in Indonesia. To increase quality of those and income producer there is a need to enhance process by introducing appropriate equipments. This study was devoted in designing and testing centrifuge for degumming of crude vegetable oils (Palm kernel oil) and vacuum deodorizer using jet pump for refining oils. The maximum capacity of sentifuge constructed is 12 liters and it was equipped with four container and 1 horse power of induction motor. The performance test of centrifuge showed reaction time for degumming was two hours with maximum impurities or gums (7%). This reaction time is shorter than those of conventional degumming process using settling tank e.g all night reaction time. Deodorizer reactor has capacity of 40 liters oil processed, and it is generated with 1,1 hp of induction motor. steam from small boiler unit was introduced to the doedorized tank to reduces impurities and free fatty acid (FFA). The reactor was equipped with metal heater element of 5000 watt which immersed in silicon oil as heating medium and it was covered by insulator. The reaction temperature of deodorizing process was 160 degree celcius. Palm kernel oil quality processed by vacuum deodorizer tested e.g. free fatty acid (FFA) was 0,03%, peroxide number was 3,03 meq/kg, moisture content was 0,94%,anisidin number was 3,97, and color were yellow and red (0,4 and 7). It means that those results of refined palm kernel oil caracteristics meet the standard required.

Abstract

Enzim yang berasal dari mikroorganisme merupakan enzim yang paling banyak digunakan dalam dunia industri karena ekonomis dan lebih stabil dibandingkan dengan enzim yang berasal dari tanaman dan hewan. Pasar global industri enzim bernilai 3,1 milyar USD pada tahun 2009 dan mencapai 3,6 milyar USD pada 2010. Produksi enzim pada fermentor skala besar perlu dilakukan optimasi pada skala bench karena sulitnya mengendalikan faktor-faktor yang mempengaruhi kinerja proses fermentasi. Tujuan dari penelitian ini adalah untuk mendapatkan kondisi optimal komposisi media dan kecepatan agitasi untuk produksi α-amilase dengan menggunakan Bacillus amyloliquefaciens T1 pada skala bench. Pada penelitian ini dilakukan produksi enzim α-amilase pada skala 50 ml menggunakan media molase dan media sintesis untuk mengidentifikasi pengaruh penggunaan media pada aktivitas enzim. Media molase menghasilkan aktivitas α-amilase 154,0 U/ml sedangkan pada penggunaan media sintesis dihasilkan aktivitas α-amilase 108,6 U/ml. Optimasi agitasi dilakukan dengan variasi agitasi 100 rpm, 150 rpm, dan 200 rpm pada media sintesis di fermentor 10 l. Kecepatan agitasi optimum pada penelitian ini adalah 150 rpm dengan aktivitas enzim maksimum adalah 38,96 U/ml pada 37°C.

Abstract

The aim of this experiment is to study the effect of harvesting age of "Pisang Ambon Jepang (Musa cavendishii Lambert) to the rate of rip g ening. The fruit age was varied from 3.5 to 4.5 months. The ripening process was induced by moisteninin dilute ethrel of 720 ppm and calcium carbide of 0.6%. The analysis was carried out soon after seven days of the ripening process. The results showed that the suitable fruit age was between 4 and 4.5 months.
