Abstract

Study the influence of surfactants on the particle diameter, viscosity and polydispersity index of Solid Lipid Nanoparticles in manufacturing (SLN) of the cocoa butter. Intended use of surfactants (lecithin and sodium dodecyl sulfate) in generating particle diameter, viscosity and polydispersity index suitable for the manufacture of Solid Lipid Nanoparticles of cocoa butter. Preparation of Solid Lipid Nanoparticles made by homogenizing a mixture of cocoa fat, distilled water and a surfactant (sodium dodecyl sulfate, and lecithin) using Ultra Thurax, speed of 1500 rpm with some formulations. Further characterized by means of Particle size analyzer (PSA). The results showed that Formula Solid Lipid Nanoparticles and surfactant lecithin produced polydispersity index is 0302-0389 and is monomodal compared to surfactant sodium dodecyl sulfate with a higher polydispersity index is above 0.5 for 0848-1215 and are polymodal. For lecithin surfactant particle diameter on particle diameter 426.2 - 654.3 nm corresponding to the diameter of Solid Lipid Nanoparticles range is 50-1000 nm. While the surfactant sodium dodecyl sulfate particles with a diameter of 2813.5 to 3976.7 nm diameter beyond the range of Solid Lipid Nanoparticles, on the use of surfactant lecithin viscosity of 0.8980 and 0.8878 and the surfactant sodium dodecyl sulfate at 0.8878.

Abstract

Wax is solid material  product and derivative product  of natural oil processing.  It has various level of smoothness. flexibility  and melting  point. PT. Pertamina  Processing  Unit (UP) V Balikpapan  is one of wax products in East Kalimantan.  Indonesia.  Pertamina produces 5 (five) types of wox which are Fully Refined Wax (FRW).  Hard Hard Paper (HHP).  Hard Semi Refined  wax (HSR).  Yellow Batik Wax (YBW)  and Match Wax  (MW). These waxes  are produced by four steps processes like dewaxing. sweating. treating  and molding. In domestic  purposes.  HHP is used for the raw material of paper  coating industry: HSR is used for the material  of lighting wax products  and for the raw material  of another  type of wax. FRW Match Wax is used the raw material  of match processing. yellow batik  wax is used for batik WaX and FRW (export grade) is used for fruit  coating industry  and cosmetic.  )n the production of sweating with VTS (vertical tube stove). domestic grade is produced and It  and it includes  HHP. HSR. Match wax and yellow botik wax. The  process of  sweating with sweating box produces export grade wax and the result is Fully Refined Wax. (FRW).  The process  of making  Fully Refined Wax in the laboratory  scale uses HSR wax with 14% oil content. yellow to brown color and grasy. melting point 580-600 C.  This process includes de-oiling process  (to reduce oil content) step by step (every 2 degrees)  heating from the temperature 480C  to 580C (melting point of oil). Therefore the change of color occurs from yellow to bright white. not oily and odorless like the type of FRW wax.

Abstract

Solid wastes generated from tanning process create a major problem for leather industry, if not handled properly will cause  problem and invironmental pollution.The tanning process of 1000 kg raw hide, will yield 150-200 kg leather and generated nearly 850 kg as solid wastes,   that is consist of solid wastes generated during pre-tanning processes as much as 80 %, while 20 % of of the wastes are caused by post tanning processes. Waste that can be processed into gelatin for food industry are generated during pre-tanning process. Acid process produce  type A gelatin, with higher yield than the alkaline process. Alkaline process produces B gelatin with gelatin characteristics such as molecular weight, viscosity, and gel strength is better than the acid process. Gelatin for food industry use : foam-forming, binders, stabilizers, fillers, coatings, nutrien enrichment, precipitate, gelling, adhesive, viscosity enhancers, emulsifier, finning agent, crystal modifier, and tickeners.

Abstract

East Kalimantan has abundant potencies of horticultural comodity of banana. The production of banana is about 25,216 ton/ year harvested from the area of 4,784 hectares (Dinas Pertanian Tanaman Pangan Propinsi Kaltim, 2002). Mostly the banana variety is pisang kepok (Musa Acuminax Balbisiana Colla) that in certain stadium can produce high carbohydrate and it is used as raw material of flour for cake and infant food industries. Currently there is a set of machines to make banana flour in agribussines sub terminal in the residence of Loa Kulu of Kulai Kertanegara Regency.To know exactly the machines performances, it is needed to conduct a performance test to every machine involved. The tests conducted in Loa Kulu showed that the actual capacity of slicing in avarage is 177kg / hour with the thickness avarage of 2 mm and the efficiency of the slicer is 27,7% on the other hand, the strainer capacity is about 1,75- kg / minute or in avarage 2,52 kg/minute. It has an avarage rendemen of 79 % and lost in process of 2,81 % more over; the dryer capacity is 11,39 kg /hour and it also has rendemen and lost in process of 24,84 % and 4,79 % respectively. In additioan, by using  a system of heat exchanger the efficiency of dryer becomes 20,49 %. Finally the disk mills making has a rendemen 87,80 % and  lost in process of 2, 56 %.

Abstract

This research aims to determine the effect of reaction temperature and the concentrations of NaOH as a catalyst in processing Crude Palm Oil into Monogliserol and Digliserol in etanolisis. The research was done by reacting the Crude Palm Oil and 95 % ethanol by using NaOH catalyst by treatment with the reaction temperature and concentration of NaOH in CPO-ethanol mole ratio of 1:6 and reaction time of 30 minutes.  The results were then analyzed to determine its ability as an emulsifier to view the product?s ability to lower surface tension and stabilize oil-water emulsion. The research result indicated that the product has a capability as an emulsifier containing compounds Monogliserol of 9,42 % and   3,35 % for Digliserol. The factor of the temperature and NaOH concentration significantly effect the stability of the emulsion and the surface tension with  concentration of NaOH the best is 3 % and the best temperature was 50 °C.
