Abstrack The background of this research is that Borax is a chemical compound called sodium tetraborate (NaB407 10 H20). If dissolved in water it will become hydroxide and boric acid (H3B03). Borax is often misused as an additional ingredient not permitted in foods that are adapted to Permenkes RI No. 1168 / Menkes / Per / X / 1999 concerning food ingredients. The purpose of this study was to determine the content of borax in meatballs in the district of Bulukumba. This type of research is a laboratory experimental study using qualitative test methods. The sample of this study was that curcumin paper did not produce changes in color on curcumin paper, the color of curcumin paper remained yellow indicating that the sample did not contain hazardous borax.

Food Attractants

For control of the Pharaoh ant, liquid baits based on 5–6 % boric acid or sodium tetraborate, with a high content of food attractant and an agent that prevents drying, are effective. The death of workers, queens and brood occurs within 2–4 weeks. In laboratory conditions, when colonies of the Pharaoh ant feed with such baits, depletion of the colony was noted by the 4th week of the experiment (death of queen was 75–100 %, and critical decrease in the number of live workers and brood was occured). Dry boric baits do not significantly affect the viability of ant colonies. Solutions of sodium tetraborate in glycerol are ineffective due to the lack of food attractants, the death of workers is comparable to that obtained in the variant with starving control. The mechanism of action and sterilizing properties of boric acid and sodium tetraborate for insects are discussed.

Properties Of Materials

The paper presents a theoretical and experimental study of experimental methods for the determination of deformability. Thus we determined the degree of deformation of copper wire by testing to traction, the fragility by means of fragility testing and the elongation of the spire sample. The experimental attempts have highlighted the fact that the properties of materials are determined with the help of the experimental methods. These The indicated test methods show the deformability of the material in the process ofplastic deformation and they are representative of physical simulation attempts.

Tolerant Strain

A strain of Bacillus firmus (designated strain KC) isolated from a boron (B) mine in California exhibited extreme tolerance to B, provided it was first acclimated at intermediate B supply concentrations. Strain KC tolerated up to 1000 mmol/L B (boric acid-B) and 1800 mmol/L B (sodium tetraborate-B), and attained the greatest growth (as measured by absorbance) at 300 mmol/L B. Despite its extreme tolerance to high B, there was no evidence that it was able to remove significant quantities of B from the growth media, suggesting that strain KC is not likely to be useful for the removal of B from wastewaters in an engineered bioreactor.
