Abstract

Abstract Pectin is used in a number of foods as gelling agent, thickener, texturizer, emulsifier and stabilizer. It is also used in pharmaceutical, dental and cosmetic industries for its jellifying properties. Commercial pectin is divided into high and low methoxy pectin. Low methoxyl pectin (LMP) is reported posses anti cancer activity. One of our local resources, green cincau (Premna oblongifolia Merr.) is one of source of LMP. Due to its wide spectrum of functional properties and its potency as anti cancer compound, hence it is urge to develop a production process of LMP from green cincau. The current technology of pectin extraction is acidic hydrolysis. It has at leat two demerits: it does not allows pectin to be extracted fully with no damage to its structure and it does not meet the environmental safety. An enzyme-hydrolytic technology seems environmentally safe and more effective in terms of pectin yield. But nowadays the main demerits of the enzymatic extraction is the high price of commercial enzyme. In order to overcome all the demerits of pectin extraction, it is proposed to enzymatically extract the pectin of green cincau by using enzyme isolated from the local resources such as cellulase which can be isolated from hepatopancrease of snail and protease isolated from Calotropis gigantea. Key Words: enzyme, extraction, low methoxyl pectin, anti cancer, green cincau

Abstract

Keluasan lingkup penggunaan enzim telah mendorong pertumbuhan pasar dan produksi enzim. Salah satu jenis enzim hidrolase yang memiliki pangsa pasar cukup besar adalah selulase. Saat ini produksi enzim selulase dari ruminansia belum banyak dilirik. Namun demikian selulase yang berasal dari ruminansia, seperti cairan rumen sapi, sangat berpotensi untuk diproduksi mengingat ketersediaan sumber isolat yang besar. Potensi limbah cairan rumen sapi di Indonesia mencapai 54,25 juta liter/tahun pada tahun 2007. Isolat enzim dari rumen sapi disebutkan memiliki berbagai kelebihan dibandingkan enzim komersial, diantaranya, lebih stabil pada suhu tinggi, aktivitas spesifik lebih tinggi, pH optimum lebih tinggi dan biaya produksi yang lebih rendah. Proses pemurnian enzim merupakan tahapan krusial dalam proses produksi enzim. Salah satu teknik pemurnian protein adalah expanded bed adsorpsion (EBA). EBA adalah teknik kromatografi pemisahan dan pemurnian produk biologi langsung dari umpan, tanpa melalui proses sentrifugasi, mikrofiltrasi dan tahap penjernihan lainnya. Mengingat unggun pada kolom dapat terekspansi, maka luas permukaan kontak adsorben lebih besar sehingga interaksi adsorben dengan molekul target lebih efektif. Dalam proses pemurnian protein menggunakan EBA, perlu ditelaah karakteristik ekspansi dan hidrodinamikanya, seperti indeks Richardson-Zaki (n), bilangan Bodenstein (Bo) dan koefisien dispersi aksial (Daxl) yang mewakili kondisi dispersi cairan dan sifat fluidisasi. Kata Kunci: selulase, cairan rumen sapi, EBA.

Abstract

Low methoxyl pectin (LMP) is reported posses anti cancer activity. LMP administering could reduce the risk of cancer, halt the progression of cancer, and in a certain percentage of cases caused the cancer cells to start to die. If this can be developed further, LMP administration could be a good co-treatment for chemotherapy or radiation. This would be a positive advancement, due to the high toxicity to the body of both chemotherapy and radiation. LMP can be produced by demethylation of high methoxyl pectin. One of our local resources that is potential for its pectin content is citrus peel. Pectin demethylation can be conducted by acid, alkali, ammonia in alcohol or enzymatic method. LMP produced by enzyme demethylation have been found to be inferior in quality to those produced by other methods. The enzyme took part in the pectin demethylation is pectinesterase. Pectinesterase can be  be isolated from various source such as fruit and vegetables. One of our local resources that is potential as source of pectinesterase is papaya.  Considering facts above thus it has a great possiblity to produce LMP from citrus peel pectin through enzymatic demethylation by utilize pectinesterase of papaya. Key-word : Low methoxyl pectin pectin (LMP), anti cancer, citrus peel pectin, papaya, pectinesterase

Abstract

Industrial effluent loaded with heavy metals are a cause of hazard to human and other forms of life. Conventional methods such as precipitation, evaporation, electroplating, ion exchange, membrane process used for removal of heavy metals from waste water however, are often cost prohibitive having inadequate efficiencies at low metal ion concentrations. Adsorption technology has become one of the alternative treatments. It is observed that appropriated modification of the raw adsorbents especially xanthates can eliminate the drawbacks of adsorbent and improve their performances significantly. Xanthates are most prominent because they are highly insoluble, easy to prepare with relatively inexpensive reagents and have high stability constant values of the metal complexes formed. Xanthates are formed by reacting an organic hydroxyl containing substrate with carbon disulfide under caustic condition. One of organic hydroxyl-containing substrate that can be used for xanthation is food processing waste. The major factors affect the biosorption process are: contact time, initial metal ion concentration, temperature, pH & biomass concentration in solution. It is postulated that metal ion adsorption process could undergo a complex formation. Most of heavy metal adsorption into the xanthate compound followed Langmuir adsorption isotherm model, and well described by the pseudo-second- order equation.  Key-word : Adsorption, Xanthate, Heavy metal

Abstract

Kondensor merupakan alat penukar kalor yang berfungsi untuk mengkondensasikan uap keluaran turbin. Kinerja dari suatu kondensor dapat dilihat dari nilai efektivitasnya. Efektivitas kondensor dipengaruhi oleh beberapa faktor antara lain aliran steam dan aliran cooling water. Faktor penting yang berpengaruh terhadap kinerja kondensor adalah banyaknya sirkulasi cooling water yang masuk ke kondensor. Kondensor yang digunakan di PT. Geo Dipa Energi Unit Dieng adalah jenis direct-contact condenser dimana cooling water disemprotkan ke dalam kondensor melalui nosel-nosel sehingga berbentuk butiran-butiran. Selanjutnya butiran-butiran tersebut akan bersentuhan langsung dengan butiran-butiran uap keluaran turbin sehingga terjadi kondensasi yang ditandai dengan pertumbuhan ukuran butiran cooling water. Dengan mengetahui pengaruh temperatur dan laju aliran massa cooling water terhadap efektivitas kondensor maka dapat diketahui performa kondensor yang ada di PT. Geo Dipa Energi Unit Dieng. Dari hasil perhitungan menggunakan metode efektivitas NTU diperoleh efektivitas tertinggi sebesar 92,02% dihasilkan pada saat temperatur cooling water yang masuk kondensor sebesar 19,89 ⁰C dan laju aliran massa cooling water yang masuk kondensor sebesar 2.392,12 kg/s. Sehingga dapat disimpulkan bahwa kondensor yang ada PT. Geo Dipa Energi Unit Dieng masih mempunyai performa yang baik.

Abstract

Abstract Wintergreen (Gaultheria fragantissima) is the source of the essential oil of wintergreen which is comprised predominantly of methyl salicylic. During this time wintergreen is not yet economically developed because of the lack of the cultivation technology. One of effort that is needed to be studied beside the cultivation tecnology and  the wintergren oil quality development is the product diversification. wintergreen comprised by far the highest concentration of both free salicylic and total salicylic acid which is expected of a plant known for the formation of the wintergreen oil, an essential oil consisting primarily of methyl salicylic. The concentration of total salicylate found in wintergreen is over 20 fold greater than the total salicylic concentration (salicylic and any derivates combined) found in Filipendula, and 100 fold greater than that found in Lemon Thyme. The active form of salicylic acid in wintergreen is Gaultherin. Gaultherin has many properties related to human health. Gaultherin consists of methyl salicylic conjugated to the disaccharide, primeverose. When plant tissues are disrupted the endogenous gaultherin is rapidly lost, presumably by enzymatic hydrolysis with the release of methyl salicylic. The problem is until this time there is not yet available an effective method for the gaultherin extraction. The difficulties faced on the gaultherin production are the fact that along the gaultherin extraction. and along with the disruption of the wintergreen tissue, the gaultherin is hydrolyzed into its individual components which are methyl salicylic and disaccharide. The alternative process for the gaultherin production from wintergreen is the gaultherin production process by enzyme inactivation and  extraction process in an inactivation extractor using a n organic solvent (alcoholic solvent extraction). This paper is intended to study the enzyme inactivation rate which is play an important role in the dimension determination of the process equipments. Enzyme inactivation can be describes as first orde reaction. The enzyme inactivation constant  kp is the temperature, pressure, and water concentration function. The dependency, model of  the temperature based on Arhenius type while the pressure dependency  is based on Eyring equation.   Keywords : gaultherin, inactivation. kinetics
