Abstract

The research is aimed to study the effect of temperature and rotation speed of mollen dryer on the characteristic of (aloe vera linn)co-crystalization.The temperature usedwere 55 degree C,60 degree C,and 65 degree C.The rotation speeds of mollen dryer are 12 rpm, 18 rpm, and 24 rpm respectively.The experimental design was the factorial random design with two replications. The result showed the best product was obtained from temperature of 60 degree C and 18 rpm rotation speed of mollen dryer.The composition of the dried aloe vera is :total sugar 56.18%,moisture content 0,84%,fiber content 0.92% and the solubility is 98.31%.While organoleptically (taste,texture,aroma,and appearane)the product was acceptable

Abstract

A study on the effect of salt concentration and the length of fermentation on "ikan peda" (a kind of fermented fish product) has been conducted. The fermentation was done in two steps; the first one using the variation of salt concentration (20, 30, and 40%), while the second was varied on its length of fermentation (10, 20, and 30 days). The first fermentation could be done for one week. The different length of second fermentation did not affect the product significantly. The result showed that the salt concentration of 30% gave the best quality of product with 47,75% moisture content and 1438% salt content.

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

 Anethol that is used in flavor, fragrance and medicine is the main component of anise oil. Pure antehol has melting point around 21.6 to 22 derajat celcius that is close to room temperature. An attempt to isolate anethole from Star anise oil (Illicum verum) a studied through freezing process has been done. It was found when the oil was cooled to 12 derajat celcius almost all the oil was solidified. The crystal contains 89% anethole that is not pore enough. When the oil was cooled at 14 derajat and 16 derajat celcius, 30% and 7% of the oil was crystallized respectively and contained 90% and 94% anethole. The experiment showed the lower the temperature, the least pure anethole was collected. A technique to isolate anethole from star anise oil can be done by fractional crystallization.

Abstract

Citronellal, citronellol and geraniol are then main components of citronella oil. They can be isolated by chemical means or fractional distillation. This study employed the second method. A perforated plate colomn, bubble cup type was used and the operation was carried out on 1:3 reflux ratio. The result showed that citronella was distilled as the first and second fraction after 85 min. The third fraction was a mixture of all components.It took 60 min. to produce 300 ml of liquid; the boiling range was 84-87 C and the separation was poor. It can be said that other than boiling point, the time of distillation should also be managed carefully. The separation depend on the time of distillation and the value of reflux ratio.

Abstract

Margarin dan cokelat tabur (meses) sering digunakan secara bersamaan sebagai selai untuk menambah cita rasa pada roti tawar. Secara komersial, kedua produk tersebut dikemas secara terpisah, dengan demikian penelitian ini dilakukan untuk memformulasi margarin dan meses menjadi satu produk olesan. Margarin dibuat dengan mencampurkan antara fase lemak (palm oil, palm stearin dan red palm oil pada rasio 70:25:5), flavor, lesitin, BHA & BHT) dan fase air (air dan garam) yang didinginkan pada suhu 4 °C dan diaduk hingga homogen. Setelah margarin membentuk kristal semi padat, sejumlah meses yang terbuat dari cocoa butter substitute, gula dan cocoa powder ditambahkan ke dalamnya dengan konsentrasi 5-50% b/b terhadap margarin. Produk di-tempering pada suhu 18-22 °C selama 2x24 jam kemudian dipindah ke ruangan suhu 28-30 °C. Mutu produk dianalisa meliputi kadar lemak, air, karoten dan gizi serta uji organoleptiknya. Hasilnya adalah produk berbentuk semi padat dengan tekstur lunak dan berwarna kuning kecokelatan. Semakin banyak cokelat tabur membuat kadar lemak, air dan karoten pada margarin menurun sementara warna semakin cokelat. Hasil uji organoleptik menunjukkan bahwa semakin banyak jumlah cokelat tabur memberikan tingkat kesukaan panelis relatif tinggi terhadap tekstur, rasa, warna dan bentuk. Produk yang paling disukai oleh panelis adalah campuran cokelat tabur sebanyak 40-50 %.

Abstract

Senyawa epoksi merupakan produk komersial yang dapat diterapkan untuk beberapa tujuan seperti plasticizer, stabilizer, dan coating resin polimer, serta antioksidan dalam pengolahan karet alam. Penelitian ini bertujuan untuk membuat senyawa epoksi berbasis minyak sawit kasar dengan melakukan optimasi proses dengan variabel pelarut, suhu, dan katalis. Penelitian ini menggunakan bahan aku minyak kelapa sawit (CPO), katalis amberlite, H2SO4, H2O2, benzena, heksana, dan asam format. Parameter yang diamati meliputi bilangan oksigen oksiran, bilangan iod, bilangan asam, bilangan penyabunan, dan fourier transform infrared spectroscopy (FTIR. Hasil penelitian menunjukan semakin tinggi perbandingan H2O2 dan asam formiat menyebabkan pembentukan senyawa epoksi yang semakin baik ditunjukan dengan bilangan oksiran yang semakin tinggi.Perbandingan yang optimum antara H2O2, dan asam formiat adalah 2:1 Hasil penelitian menunjukan bahwa kondisi yang optimal pembuatan epoxy diperoleh dengan menggunakan pelarut benzene sebanyak 25% dari CPO, katalis amberlite, pada suhu 70C selama 6jam. Hasil analisis menunjukan bilangan oksigen oksiran 6, 20% bilangan iodium 12,6 (g iod/100g), bilangan asam 8,96 (mg KOH/g), bilangan penyabunan 202 (mg. KOH/g).
