Abstract

Tannin is a  derivative from organic compound from glycosides found in various plants, the most important commercial condensed tannin oblained from gymnosperms species for example Acacia mangium. Tannin is one of the  adhesive  materials  that  can have  a  dimensional stability  of  wood. Tannin contains flavonoid compounds that have hydroxyl groups that are reactive to condense against   other materials   as a cross-link agent, like formaldehyde, which may increase the number of polymer units of tannins, thus increasing the bonding strength of tannin based adhesives. Based on the results of physicochemical analysis of extracts (tannins) from the bark of A. mangium  as a raw material for adhesives, it can be concluded  that the A.  mangium tannin   had a higher reactivity toward formaldehyde of 96%,  reactivity  of  tannin  toward  hexamefhylene  tetramine  of  46.18%, tannins toward ethylene glycol of 3.07% and tannins toward dimethylol urea of   183.59%.    Meanwhile,   the   value  of   reactive   polyphenol   content determined by UV-Method showed in tannin with formaldehyde of 97.65%, tannins with hexamethylene tetramine of 46%,  tannins with ethylene glycol of 2%,  and tannins with dimelhylolurea of 56.26%.   The resuits of gelation time   (gel time) measurements fullfilled the requirements of JIS K 6833-1980 by the treatment of hexamelhylenen tetramine for variable II and III, and  the treatment of ethylene glycol (variable VI). The viscosity values by the  Ireatment of hexamethylenen  tetramine (variable II, III, and  IV), for ethylene glycol (variable II  -  VI)  met the requirement conditions  by JIS K 6833-1980.

Abstract

Physico-chemical properties  and enti-becterial agent of liquid smoke palm shell  for food preservation has been performed.  The liquid smoke  was made by dry distillation method, and then partially purified by precipitation­ filtration and distillation. Chemical components were assayed using GC-MS and  anti  bacteria.  capacity  was  assayed  using agar  diffusion  method. Results showed that differences in purification treatment leads to a different physico-chemical  properties  and  anti bacterial  capacity of liquid  smoke produced.  Partially purified  of pure  liquid smoke produced  followed by distillation process have characteristic of clear, impurities of 0.09% and pH of 3.07 .Dominant chemical compounds found in the various treatments were cyclopentanone, 2-furancarboxaldehyde. acetic acid. and acid propanoate.  Partial purified liquid smoke by precipitation-filtration showed inhibition on bacterial growth of E. Coli and S. aureus. but could not inhibit the  growth  of  Salmonella,  whereas partial  purified  of  liquid  smoke  by distillation did not have inhibitory effect on the growth of E. Coli, S aureus and Salmonella.

Abstract

Silk sarongs Samarinda produced by home industrie in Samarinda were still pale and faded. It was caused by the improper (or incorrect) coloring process usually done by the industries. This research was done to improve the coloring process and to increase the quality of sarong Samarinda. In this  research,  polyethylene  glycol  dioleat  was  added  into  the  dyeing medium  and the acidity of the medium was measured. Then the silk was washed and dried under the sunshine.  The dried silk was tested for its colour  fastnees  through  washing  and  ironing process.  Results  of  this research  showed that addition of  polyethylene glycol dioleat into dyeing medium of sarong Samarinda can improve the quality of polyester material, but it did not produce good result on silk and cotton material.

Abstract

Research  on the correlation  test  for chemical  oxygen demand and  the colors in liquid waste of oil palm plant has been conducted through three steps, they are the first lest on some liquid waste oil palm plant, test on some variations of diluting sampel and lest on the aplication of the results of the research. The test on COD and colors in liquid waste of oil palm plant show the existence of corretetion which is marked by the linear equation which is oblained and the close correlation (R).  The linear equation and correlation (R) are:  Y = 0.19 X  + 0,20 ; R = 0,99 for inlet sample and Y =  0,19 X + 0,14; R = 0,99 for outtet sample The  aplicaton  if  the  results  of  fhe research  also shows  the  difference between result of the test on COD and COD of the color test are very small. at the average of 4, 1%.

Abstract

Tiwai onion bulb extract (EBT) contain phenol compounds that be used as an antioxidant ingredients.   Utilizalion tiwai onion bulb extract as an antioxidant is expected to increase the value and  utilization tiwai onion bulbs.  This research  was conducted  to obtain  tiwai onion  bulb  extrect concentration as antioxidant ingredients of coconut oil. Extraction process is  done  by  adding  96% ethanol  solvent /0  onion  liwai  flour  and  tnen incorporated into tile glass beaker. allowed to stand for 24 hours and then filtered to obtain a liquid extract. Rendement liwai onion bulb extract solvent 96% ethanol is 10,2%. The average value of total phenol content of onion bulb  extract  tiwai  solvent  96%  ethanol  is  0,043±0,001ppm. Tile liquid extract was then performed vacuum evaporation and the obtained furter extract tiwai and then put in oven vacuum. Extract obtained is then inserted into tne coconut oil, and then analyzed with the parameters of color, odor. proxide number and acid number, with storage time for 3 months. Based on test result, it is obteined that the concentretstions of tiwai onion bulb extract 100-200 mg/kg was able to maintain storage time of coconut oil until the 3 mont period specified in the study.
