Even though machinery has replaced many elements and is now a significant part in manufacturing processes, problems that must be solved with respect to current process flow to increase efficiency still exist. The paper-s aim is to increase productivity while maintaining desired quality of starch, by redesigning the flipping machine-s mechanical control system which has grossly low functional lifetime. Such problems stem from the mechanical control system-s bearings, as fluids and humidity can access into said bearing directly, in tandem with vibrations from the machine-s function itself. The wheel which is used to sense starch thickness occasionally falls from its shaft, due to high speed rotation during operation, while the shaft may bend from impact when processing dried bread. Redesigning its mechanical control system has increased its efficiency, allowing quality thickness measurement while increasing functional lifetime an additional 62 days. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Control%20system" title="Control system">Control system</a>, <a href="https://publications.waset.org/search?q=Machinery" title=" Machinery"> Machinery</a>, <a href="https://publications.waset.org/search?q=Measurement" title=" Measurement"> Measurement</a>, <a href="https://publications.waset.org/search?q=Potato%0Astarch" title=" Potato starch"> Potato starch</a> </p> <a href="https://publications.waset.org/11658/programmable-logic-controller-for-cassava-centrifugal-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/11658/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/11658/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/11658/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/11658/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/11658/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/11658/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/11658/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/11658/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/11658/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/11658/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/11658.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2098</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">22</span> Extraction Condition of Phaseolus vulgaris</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=Ratchadaporn%20Oonsivilai">Ratchadaporn Oonsivilai</a>, <a href="https://publications.waset.org/search?q=Jutarat%20Manatwiyangkool"> Jutarat Manatwiyangkool</a>, <a href="https://publications.waset.org/search?q=Anant%20Oonsivilai"> Anant Oonsivilai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Theoptimal extraction condition of dried Phaseolus vulgaris powderwas studied.

However, there are still lacks of accurate knowledge in the field of biological properties, functional properties, including the application of legume in foods. This study focused on antioxidant activity of soybean (SB) and fermented soybean (FSB) crude extracts evaluating to have more information in fortification SB and FSB crude extracts in food products and/or dietary supplement. SB and FSB crude extracts were prepared by infusion with water and ethanol. The antioxidant activity of crude extracts was studied with DPPH and ABTS assay including commercial standard. From both DPPH and ABTS assay, the antioxidant activity of SB and FSB water crude extract showed higher antioxidant activity than ethanol crude extract, and FSB crude extract showed higher antioxidant activity than SB crude extract. In DPPH assay, BHT and vitamin C showed IC50 values at 0.241, 0.039 mg/ml, in ABTS assay. In addition, Trolox showed IC50 at 0.058 mg/ml respectively. FSB water crude extract showed high antioxidant activity. Finally, the functional properties study of both water and ethanol crude extracts should be done for beneficial in application of these extracts in food products and dietary supplement in the near future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Antioxidant%20activity" title="Antioxidant activity">Antioxidant activity</a>, <a href="https://publications.waset.org/search?q=Fermented%20soybean%20%28FSB%29%0Acrude%20extracts" title=" Fermented soybean (FSB) crude extracts"> Fermented soybean (FSB) crude extracts</a>, <a href="https://publications.waset.org/search?q=soybean%20%28SB%29%20crude%20extracts." title=" soybean (SB) crude extracts."> soybean (SB) crude extracts.</a> </p> <a href="https://publications.waset.org/13758/soybean-and-fermented-soybean-extract-antioxidant-activities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/13758/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/13758/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/13758/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/13758/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/13758/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/13758/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/13758/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/13758/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/13758/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/13758/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/13758.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">4376</span> </span> </div> </div> <div class="card publication-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">17</span> GRNN Application in Power Systems Simulation for Integrated SOFC Plant Dynamic Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/search?q=N.%20Nim-on">N.

In order to comparison effect of chemical contents, silicone rubber outdoor polymer insulators having same configuration and leakage distant from two manufactures were tested together continuously 30,000 test cycles. Many discharge activities were observed in during the test. After 30,000 test cycles, in spite of same configuration, differences in degree of surface aging were observed. Physical analysis such as decreasing in hydrophobicity and increasing in hardness measurement were measured on two-type tested specimen surface in order to confirm degree of surface ageing. Furthermore, chemical analysis by ATR-FTIR to diagnose the chemical change of tested specimen surface was conducted to confirm the physical analysis results. <p
