TEPUNG PUPA-MULBERRY (PURY) SEBAGAI BAHAN PANGAN ALTERNATIF KAYA GIZI

Silkworm pupae is immature stage of moth. It is inner part of the silkworm cocoon shell which usually disposed from yarn silk production, and now has become a valuable ingredient of human food in many countries, however it is not common yet in Indonesia. The purpose of study is to develop a weaning food as nutritious basic formula of complementary food from pupae waste. A silkworm pupae was a major constituents used as materials. There are sixth steps to get PURY properly: select a fresh, fine and clean pupae, steamed well about 10 seconds, grinded and sifted it to get liquid, added 10% maize powder, dried in oven at 60ºC for 6 hours, and refine on blender. A fine powder, so called “PURY”, has a well balanced amount of moisture, protein, fat included PUFA, carbohydrate, amino acids, vitamins and minerals. Through a simple processing, the dry product of fine PURY powder can be obtained and used as a basic formula of complementary food and snacks and has made great contribution to reduce pupae waste. Research is continued to scale up producing PURY based product for more food-technological uses in order to reduce prevalence of malnutrition in Indonesia.

Considerable Damage

The silkworm maggot, Exorista sorbillans, is a well-known larval endoparasitoid of the silkworm Bombyx mori that causes considerable damage to the silkworm cocoon crop. To gain insights into the response mechanism of the silkworm at the protein level, we applied a comparative proteomic approach to investigate proteomic differences in the hemolymph of the female silkworm pupae parasitized by E. sorbillans. In total, 50 differentially expressed proteins (DEPs) were successfully identified, of which 36 proteins were upregulated and 14 proteins were downregulated in response to parasitoid infection. These proteins are mainly involved in disease, energy metabolism, signaling pathways, and amino acid metabolism. Eight innate immune proteins were distinctly upregulated to resist maggot parasitism. Apoptosis-related proteins of cathepsin B and 14-3-3 zeta were significantly downregulated in E. sorbillans-parasitized silkworm pupae; their downregulation induces apoptosis. Quantitative PCR was used to further verify gene transcription of five DEPs, and the results are consistent at the transcriptional and proteomic levels. This was the first report on identification of possible proteins from the E. bombycis-parasitized silkworms at the late stage of parasitism, which contributes to furthering our understanding of the response mechanism of silkworms to parasitism and dipteran parasitoid biology.

Growth Constraints

A critical question facing Microfinance Institutions (MFIs) is whether they can attract commercial capital as a solution to their financing problem and as a way of relaxing strained development aid. While donations have made enormous contributions to microfinance development and poverty reduction among the poor to date, an attempt to scale-up funding from this traditional source has been an uphill task. It is argued that vast resources of commercial capital can become available to microfinance if critical success strategies of access to commercial funding are developed. This paper offers research evidence that identifies significant predictors for successful Commercialization of microfinance based on firm-level data from African MFIs for three financial years between 1998 and 2003. The research develops and tests a commercial rating rule (predictive model) for determining success in tapping commercial capital. The results indicate the emergence of new finance sources, widened financing options for MFIs and the capacity to relax growth constraints in the industry. However, the findings also suggest the need for MFIs to satisfy the interests and requirements of prospective commercial investors to overcome new challenges.

Microstructural Studies

Aluminum additions to conventional 18Cr-8Ni austenitic stainless steel compositions impart excellent resistance to high sulfur environments. However, problems are typically encountered with aluminum additions above about 1% due to embrittlement caused by aluminum in solid solution and the precipitation of NiAl. Consequently, little use has been made of aluminum alloy additions to stainless steels for use in sulfur or H2S environments in the chemical industry, energy conversion or generation, and mineral processing, for example.A research program at the Albany Research Center has concentrated on the development of a wrought alloy composition with as low a chromium content as possible, with the idea of developing a low-chromium substitute for 310 stainless steel (25Cr-20Ni) which is often used in high-sulfur environments. On the basis of workability and microstructural studies involving optical metallography on 100g button ingots soaked at 700°C and air-cooled, a low-alloy composition Fe-12Cr-5Ni-4Al (in wt %) was selected for scale up and property evaluation.

The (110) twin structure of YBa2Cu3O7 superconductor oxide, which is formed to reduce the strain energy of the tetragonal to orthorhombic phase transformation by alternating the a-b crystallographic axis across the boundary, was extensively investigated. Up to now the structure of the twin boundary still remained unclear. In order to gain insight into the nature of the twin boundary in Y-Ba-Cu-O system, a study using electron diffraction techniques including optical and computed diffractograms, as well as high resolution structure imaging techniques with corresponding computer simulation and processing was initiated.Bulk samples of Y-Ba-Cu-O oxide were prepared as described elsewhere. TEM specimens were produced by crushing bulk samples into a fine powder, dispersing the powder in acetone, and suspending the fine particles on a holey carbon grid. The electron microscopy during this study was performed on both a JEOL 2000EX and 2000FX electron microscopes operated at 200 kV.

Photovoltaic Applications

Tin mono selenide (SnSe) with an energy gap of about 1 eV is a potential material for photovoltaic applications. Various authors have studied the structure, electronic and photoelectronic properties of thin films of SnSe grown by various deposition techniques. However, for practical photovoltaic junctions the electrical properties of SnSe films need improvement. We have carried out investigations into the properties of flash evaporated SnSe films. In this paper we report our results on the structure, which plays a dominant role on the electrical properties of thin films by TEM, SEM, and electron diffraction (ED).Thin films of SnSe were deposited by flash evaporation of SnSe fine powder prepared from high purity Sn and Se, onto glass, mica and KCl substrates in a vacuum of 2Ø micro Torr. A 15% HF + 2Ø% HNO3 solution was used to detach SnSe film from the glass and mica substrates whereas the film deposited on KCl substrate was floated over an ethanol water mixture by dissolution of KCl. The floating films were picked up on the grids for their EM analysis.
