ANALISIS KADAR PENGAWET BORAKS PADA BLENG DAN KERUPUK PULI YANG DIPRODUKSI OLEH BEBERAPA HOME INDUSTRI KABUPATEN MAGETAN

Puli crisply is one of kind crisply which made of rice upon. Beside that, oftentimes the processing is enhanced by bleng. Bleng is phosphate salt condensation, in form of crystal, and yellowish chromatic, the content have many boron element and some other mineral. There many function of Bleng, it is for preservative. Not only that but also for developer. The usage of Borax to food materials was prohibited, if swallowed can result effect at center nerve formation, liver and kidney. Target of research to know Borax of preservative rate found on puli crisply and \ud bleng, it also know have as according to regulation of MENKES RI No 722/Menkes/Per/IX/tahun 1988. \ud This research is executed in Chemical Laboratory at University Muhammadiyah of Malang on July 26 until August 2nd 2007. The Research of descriptive eksploratif, population in this research is produced by puli crisply from 5 industrial home in Sub-Province Magetan, the sample \ud used Crisply puli from 5 industrial home each by 3 restating times, rill, industrial home have enlisted with permission on duty health. \ud The result of research that Borax presentative type which implied in puli crisply and the usage of bleng was prohibited by Permenkes RI. Standartitation Permenkes RI about usage of Borax at adult among 15-20 and children about 3-6 gr. The result Of Sour Analysis of Borat by using \ud Titrimetri method, obstetrical of Highest borax at Bleng UD. GM with Borax rate 1.359 %, and lower of Bleng UD. MN with Borax about 1.087 %. \ud The highest Rate Borax puli crisply that industrial home of MN equal to 0.658 % and the lower at industrial home of YD equal to 0.494 %. Result Of Sour Analysis of Borat by using \ud Spektrofotometri method, obstetrical of Highest borax at Bleng UD. GM with Borax rate 1361.71 of lower and Bleng UD. MN with Borax rate 1087.81 ppm. The lower of Puli Crisply \ud which is at industrial home of YD equal to 492.82 ppm and highest which in industrial home of MN equal to 660.13 ppm

Gambaran Histopatologi Hati Tikus Wistar Yang Diberikan Boraks

: Borax is an ingredient that is widely used for industrial or antiseptic cleaning agents that are toxic, but borax is used as an additive ind foods and any experience accumulated in the liver that can cause liver disfumction. Methods: The aim of research is to see macroscopic and microscopic of live wistar rats were given different doses of borax. Rats were used as much as 10 animals were divided into 4 groups. The control group (K1) 1 rat, K2 ( borax 20mg), K3 (borax 30 mg), K4 (borax 40 mg) each of 3 rats by administration for 1,5 and 10 days. Result: The result showed the rats had grossly enlarged liver size, liver weight gain and blackish brown in the group given 40 mg of borax and microscopically, the cells were exposed to borax liver showed hydropic degeneration, proliferation fibrolas and fibrosis. From this study it can be concluded that the administraion of borax 20mg, 30mg, 40mg for 10 days caused fatty liver and mild fibrosis

Epsomite as flame retardant treatment for wood: Preliminary study

The effect of epsomite as flame retardant for wood has been investigated and compared with a commercial boron salt. Both flame retardants have been introduced into wood samples by vacuum impregnation. Epsomite is a hydrated sulphate salt with a water solubility of 731 g L-1 at room temperature. Thanks to this high solubility it was possible to obtain elevated epsomite loadings in comparison with the borax salt. Flame retardancy was evaluated by means of the limiting oxygen index, the dripping test and the exposition to a direct flame (Bunsen test). The results showed that the addition of epsomite increases the limiting oxygen index, delays the time to ignition and the evolution of the temperatures trough the wood. © 2016 Elsevier LtdPeer ReviewedPostprint (author's final draft

A Study of the Use of Borates in Semi-Chemical Pulping

The purpose of this project was to identify sodium metaborate as a pulping chemical in semi-chemical pulping with soda ash. The experimental design included four digester cooks with 0%, 10%, 20%, and 40% addition of.the borate compound. The resulting yields were 81. 3 %, 79. 2%, 77.4 %, and 7 4. 5% respectively. Therefore, under the definition of pulping, sodium metaborate was considered a pulping chemical. The pulps were mechanically refined. The resulting screened rejects increased with increasing borate addition. Handsheets were made and tested for strength and optical properties. The tensile and mull en strengths of the handsheets increased with addition of borates up to 20%, but degradation of the bonding properties occurred at high addition levels (40%). The tear strength increased dramatically (up to 24.1%) with the addition of borates to the pulping liquor. Brightness and visual color were slightly improved. The results indicate that the sodium metaborate was an effective pulping chemical with a tendency to be selective in delignification. Further work should be performed to compare the effect of substitution against conventional non-borate pulping, and possible changes in bleached pulp quality

Development of durable “green” concrete exposed to deicing chemicals via synergistic use of locally available recycled materials and multi-scale modifiers

From the economic and social perspectives, the use of waste materials would not be attractive until their costs and quality can satisfy the construction requirements. In this study, a pure fly ash paste (PFAP) was developed in place of ordinary Portland cement paste (OPCP). This PFAP was prepared at room temperature and without direct alkali activation. The samples were prepared using only the as-received class C coal fly ash, water, and a very small amount of borax (Na2B4O7). On average, the PFAP featured 28-d compressive strength of about 36 MPa, and micro-nano hardness and elastic modulus 29% and 5%, higher than the OPCP, respectively. These mechanical and other properties of the PFAP make it a viable “green” construction binder suitable for a host of structural and non-structural applications. Advanced characterization of the raw material and PFAP pastes was employed to elucidate the hydration mechanisms of this “green” binder. The obtained knowledge sheds light on the role of class C CFA in the hydration process and may benefit the expanded use of various CFAs in cementitious materials
