<p>Research of effect filler addition in drying to nutrient component exchange in storage of processed organic wastes of kitchen and restaurant hotel’s was done at the laboratory of feed Technology, Departemen of Animal Nutrition and Feeding, Faculty of Animal Science UNDIP, Semarang. The research was aimed to study effect of filler addition in drying process of organic wastes of kitchen and restaurant hotel’s so the qualityy of product observed from proximate component and total fungi exchange during storage. Experiment was conducted by factorial completely randomized design (CRD-factorial) 3x2x3. Organic wastes of hotels class 1,2 and 3 dried by adding filler 0 and 15% and were stored for 0, 4 and 8 weeks. Component proximate i.e.: crude protein (CP), crude fat (CF), crude fiber (CF), Ash and Nitrogen Free extract (NFE) and total fungi are parameter observed. Data were statistically analyzed by Steel and Torrie (1981).</p><p>The result showed that interaction effects of rice brand addition and time of storing are significant to EE, CF and NFE (P&lt;0.05), but the effect to CP and Ash are not significant (P&gt;0.05). interaction between hotel class, filler and storing significantly affected total fungi in the processed product (P&lt;0.05).</p>

Capture Techniques

We have employed cryoelectron microscopy to visualize events that occur during the freeze-drying of artificial membranes by employing real time video capture techniques. Artificial membranes or liposomes which are spherical structures within internal aqueous space are stabilized by water which provides the driving force for spontaneous self-assembly of these structures. Previous assays of damage to these structures which are induced by freeze drying reveal that the two principal deleterious events that occur are 1) fusion of liposomes and 2) leakage of contents trapped within the liposome [1]. In the past the only way to access these events was to examine the liposomes following the dehydration event. This technique allows the event to be monitored in real time as the liposomes destabilize and as water is sublimed at cryo temperatures in the vacuum of the microscope. The method by which liposomes are compromised by freeze-drying are largely unknown. This technique has shown that cryo-protectants such as glycerol and carbohydrates are able to maintain liposomal structure throughout the drying process.

General Method

The energy analysis of electrons scattered by a specimen in a scanning transmission electron microscope can improve contrast as well as aid in chemical identification. In so far as energy analysis is useful, one would like to be able to design a spectrometer which is tailored to his particular needs. In our own case, we require a spectrometer which will accept a parallel incident beam and which will focus the electrons in both the median and perpendicular planes. In addition, since we intend to follow the spectrometer by a detector array rather than a single energy selecting slit, we need as great a dispersion as possible. Therefore, we would like to follow our spectrometer by a magnifying lens. Consequently, the line along which electrons of varying energy are dispersed must be normal to the direction of the central ray at the spectrometer exit.

X Ray Absorption

The present developments of electron energy analysis in the microscopes by E.E.L.S. allow an accurate recording of the spectra and of their different complex structures associated with the inner shell electron excitation by the incident electrons (1). Among these structures, the Extended Energy Loss Fine Structures (EXELFS) are of particular interest. They are equivalent to the well known EXAFS oscillations in X-ray absorption spectroscopy. Due to the EELS characteristic, the Fourier analysis of EXELFS oscillations appears as a promising technique for the characterization of composite materials, the major constituents of which are low Z elements. Using EXELFS, we have developed a microstructural study of carbon fibers. This analysis concerns the carbon K edge, which appears in the spectra at 285 eV. The purpose of the paper is to compare the local short range order, determined by this way in the case of Courtauld HTS and P100 ex-polyacrylonitrile carbon fibers, which are high tensile strength (HTS) and high modulus (HM) fibers respectively.

The purpose of the study are to (1) review the main problems faced by the factory of Kepuruk Manunggal Karsa (MK), and (2) assessing the entrepreneur attempts to be able to solve the problems faced. The research was carried out using qualitative descriptive design. The results showed that (1) the lack of supply of raw materials as a result of lack of capital. Sequel is due, the difficulty of the plant to meet consumer demand (excess demand). (2), the system of capital used is circulating capital (capital turnover). Earned income used up to finance the operation of the plant. (3) Innovation has been done in the form of deal with bad weather (rain) as an effort of crackers drying process is by using the oven. (4) There has been no cooperation with financial institutions. (5) There is no organizational structure as a modern factory for traditionally managed by family management. (6) Marketing using modes of transportation carts and motor vehicles.
