PENGARUH ASAM CUKA SAGUER TERHADAP SIFAT ORGANOLEPTIK DAGING ITIK SERATI (Cairina moschata)

THE EFFECTS OF PALM JUICE VINEGAR TOWARDS THE ORGANOLEPTICS OF MUSCOVY DUCK MEAT (Chairina moschata). People in North Sulawesi are continued to develop duck farming. Most of them run their farm with traditional system. The species of duck developed in North Sulawesi of Chairina moschata is called Muscovy duck. Special treatments were applied in cook processing of duck meat especially to eliminate stink and tough texture. Palm juice vinegar containing acetic acid has many roles when it was added in foods stuffs including duck’s meat. The aim of this research was to evaluate the organoleptic taste of duck meat immersed in palm juice vinegar. The objects of this research were breast part of duck meat immersed and in juice vinegar and stored during 4, 8 and 12 days. This research used completely randomized design involving 4 treatments with 40 untrained panelists as replication. Observed variables were colors, flavors, meat tastes and meat tenderness. Data was analyzed using ANOVA and Duncan Multiple Range Test (DMRT) for further significant treatments. The results showed that immersion treatment of duck meat in palm juice vinegar stored during 4, 8 and 12 days gave significant effects (P<0.01) to organoleptic of duck meat. Further test with DMRT showed that immersion of duck meat in 12 days palm juice vinegar can be accepted by the panelists as the best treatment.   Keywords: Organoleptic test, duck meat, palm juice vinega

Status and First Operation of Gyrotron Teststand FULGOR at KIT

FULGOR, the new KIT gyrotron teststand for megawatt-class gyrotrons, will be presented. Results of initial experiments using a 1.5 MW 140 GHz short pulse pre-prototype gyrotron will be discussed

Automated Generation of High-Order Modes for Tests of Quasi-Optical Systems of Gyrotrons for W7-X Stellarator

A test system for the verification of the quasi-optical converter system is vital in the gyrotron development. For this reason, an automated measurement setup has been developed and is benchmarked with the TE$_{28,8}$ mode operating in the cavities of the gyrotrons of W7-X with a high purity of about 95 % and a counter-rotating amount of about 0.3 %. The time duration for the mode generator adjustment has been reduced to two days for this mode. After a successful mode excitation, the quasi-optical mode converter, consisting of a launcher and three mirrors, is measured having a vectorial Gaussian mode content of 97 %

Experimental Testing of the European TH1509U 170-GHz 1-MW CW Industrial Gyrotron – Long Pulse Operation

The upgraded European 1-MW, 170-GHz continuous wave (CW) industrial prototype gyrotron (TH1509U) for electron cyclotron resonance heating and current drive in ITER was tested at the Karlsruhe Institute of Technology (KIT). In this work, we report on the major achievements during the experimental campaigns that took place intermittently between October 2020 and July 2021. The upgraded gyrotron clearly surpassed the performance of the previous TH1509 tube. In particular, TH1509U delivered (i) 0.9 MW in 180 s pulses (maximum possible pulse length with the KIT test stand) and (ii) more than 1 MW at a pulse length limited to 40 s, due to an unforeseen problem with the test stand cooling circuit at that time. In addition, it was possible to also demonstrate gyrotron operation at (iii) 0.5 MW in 1600 s pulses. The experiments will be continued at the FALCON test stand at the École Polytechnique Fédérale de Lausanne (EPFL)
