Abstract

The oil paten fish (pangasius sp.) is a by product of paten nugget processing. It contains fatty acid and other nutriens compounds utilized in food and pharmaceutical industries. Refining is needed to utilize the raw oil fish of patin. The aim of this research was to find out a refining technology of patin oil fish by trretment of degumming. The research used two trreatment of degumming using 2.5% of salt (NaCI) an 2.0% of phosphate acid (H2PO4). Both were neutralized with Sodium Hydroxide (NaOH) and bleached with actived carbon. The reslt showed that the more accurate technique to refine oil fish of patin was by degumming process using 2.5% of salt, neutralization with NaOH and bleaching with actived carbon. The testing of pure oil fish of patin resulted in a metting to the requirement of food and pharmaceutical industry

Abstract

Data relating to physical properties and characteristic of dried mushroom was very useful information especially for packaging, storage, and transportation purposes. The objectives of this study were to investigate some physical characteristics covering, rehidration coefficient, shear stress, as well as rendement of mushroom affected by drying. The drying experiment were conducted at 4 level temperature (35 derajat celcius, 40 derajat celcius, 45 derajat celcius and 50 derajat celcius), and level 4 drying air speed (1 m/sec, 1.5 m/sec, 2.0 m/sec, and 2.5 m/sec) with and without blanching treatment. Dried mushroom with blanchead treatment gave better rendement (aximum 12,67%) and shear stress value (maximum 18954,00 Newton/m2) comparing with those without blanched treatment. In the other hand dried mushroom with blanched treatment showed better appearance and rehiration coefficient (maximum 4,31) than those without blanched treatment.

Abstract

It is so far the world haevily depends on the petroleum oils to fulfill energy consumption such or automotives,industry,generators,heating, agricultural machineries and other energy needs.It was predicted that the world oils reserves will be exhausted in the next 17 years because of its nonrenewable characteristic.Many alternative energy resources have been employed to overcome energy crisis by a lot of countries in the world including Indonesia.Many eeforts have been made to anticipate the scarcity of petroleum oil.Recently,Indonesia and many other countries has develop biodisel which and chemically defined as a methyl ester derived from renewable resources such jatropha oil,palm oil,used frying oil,and other resources.Biodisel sometime addresed to also as FAME (Fatty Acids Methyl Ester)or VOME (Vegetable Oil Methyl Ester) to reccal its chemical origin.Comparing with petroleum diesel the use of bio-diesel has some benefits such as clean burning,renewable,nontoxic and biodegradable fuel.Bio-diesel can be used alone or in blends with petroleum-derived diesel.Basically bio-diesel is made through trans-esterification process with methanol.In lands availabity and technology point of view of bio diesel can produced for both industrial and rural area scale.Petroleum diesel consumption in Indonesia at the time being in around 150.000 MB.Unit now the deficid is fulfilled by import.Currently more than 1 millionton of vegetable oil methyl ester are being produced and used in the world as alternative fuel for engines and for heating.

Abstract

Tepung gaplek dapat dipergunakan untuk substitusi terigu pada pembuatan roti. Penambahan 25% tepung gaplek dapat menghasilkan roti yang mempunyai penampakan, warna, bau, rasa, dan tekstur yang masih dapat diterima konsumen. Peningkatan kandungan protein dengan penambahan gluten kering tidak memberikan pengaruh yang berarti terhadap penambahan volume roti yang dihasilkan. Tingkat substitusi 50% menghasilkan volume roti yang lebih kecil dibandingkan dengan substitusi 25%.Hal yang sama juga diperoleh dengan penambahan bahan penolong.

Abstract

Torefaksi adalah suatu proses termokimia yang dilakukan pada temperatur 200-300°C dengan kondisi tanpa udara. Proses ini berfungsi untuk mengubah biomassa menjadi bahan bakar padat yang relatif mempunyai kandungan energi yang lebih tinggi dari sebelumnya. Torefaksi dapat meningkatkan kerapatan energi, tahan air, memudahkan penggilingan,  membuatnya  aman dari degradasi biologis, memudahkan transportasi dan penyimpanan. Penelitian ini bertujuan untuk meningkatkan karakteristik pellet biomassa cocopeat (yang merupakan hasil samping pengolahan sabut kelapa) menjadi bahan bakar padat dengan penerapan proses torefaksi Biomassa cocopeat dibuat menjadi bentuk pellet dengan proses pengeringan, pengayakan, pengadukan, dan pemelletan.  Pellet yang dihasilkan selanjutnya ditorefaksi pada suhu 300oC selama 1,5 jam  dan hasilnya dibandingkan cocopeat dengan tanpa perlakuan torefaksi  untuk melihat kandungan energinya pellet.  Hasil kedua perlakuan pellet cocopeat tersebut selanjutnya juga dibandingkan untuk melihat kandungan kualitas emisi udara yang dihasilkan saat pembakaran. Hasil penelitian menunjukkan bahwa kandungan energi dari pellet cocopeat dengan perlakuan torefikasi menunjukkan peningkatkan energi sebesar 36%. Sementara emisi udara yang dihasilkan dari pembakaran memenuhi persyaratan  standard emisi udara sesuai  peraturan yang berlaku.

Abstract

Aloe vera linn is neended in industries as rwa material for cosmetics, pharmacy and beverages.The types of aloe product which are available are in the form of gel,juice and powder.Aloe powder has more advantages in many cases than the other thypes.the research was conducted to study the-effect of filler in producing aloe powder.Fillers used were arabic gum and carboxyl methyl cellulose (CMC). The concentration of arabic gum applied was 1%,2% ,3% ,4%, and 5%,while the concentration of the mixed arabic gum and CMC was 2% with the ratio of 1:1,1:2,1:3,1:4,and 1:5.The best result was found with 2% filler of mixed  arabic gum and CMC with the ratio of 1:2,where pH was 5.25 and the ratio between product and the raw material was about 1:200.The viscosity of 2.50% of liqid from reconstitution of the aloe powder was 9.34 centipoise.

Abstract

The experiment was aimed to observed effects of type and amount of added hydrocolloids to texture characteristic of black cincau gel prepared from gel froming compound powder. three types of hydrocolloids added are arabic gum, kappa-carrageenan, and alginic acid. the texture characteristic observed were included breaking point, breaking strength, rigidity, height decrease and syneresis. The result showed that arabic gum and alginic acid has synergistic effect in black cincau gel formulation, while kappa-carrageenan has antagonistic one. the addition of arabic gum resulted in the lowest values of rigidity, height, and syneresis at addition level of 5 per cent. on the contrary, addition of kappacarrageenan resulted gel with breaking point, breaking strenght, and heihgt decrease which decreases with the increasing of addition. while addition of alginic acid produced gel with various texture characterics, depended on the level of addition.

Abstract

Experiments on the distillation and characterization of mentha leaves essential oil have been done using three type of leaves, e.g. Mentha arvensis var.piperascence ex Sukabumi and Bogor, and Mentha arvensis var. javanica ex Bogor. The yield of oil were 2.0%;1.8% and 2.7%, respectively. Menthol content of the oil were 67.6% (mentha arvensis var. piperascence ex Sukabumi) and 53.6% (M.arvensis var. piperascence ex Bogor). No menthol can be detected in the oil of M.arvensis var. javanica.
