Abstract

The case of the devastating flood of hot mud from gas drilling PT. LAPINDO Brantas inPorong Siring village of Sidoarjo regency of East Java on 29 May 2006 caused tremendous lossimpact. Puddle and a large volume of mudflow an issue as well must be immediately sought a wayto use it. Business of mud matching is the manufacture of building materials, especially materials ofred brick. It is based on UMM Lumpur research Team (2006) that the Lapindo mud can be used asan ingredient brick-making raw because they contain clay. This study aims to gain prototype madeof mud bricks in accordance with the level / class of bricks.This study is an experiment, the experimental design "One Group Pretest-posttest Design ". Inthis study independent variables consisted of percentage mud in clay 0%, 10%, 15%, 20%, 25%,30%, 35%, 40% and the dependent variable compressive strength, water absorption and solid brickattached brick.Research results indicate brick class I achieved on the percentage of mud in clay 15% to 25%.While the percentage of sludge 0%, 10%, 30%, 35% will produce bricks class II and the percentageabove 35% would produce a level lower bricks of stone normal brick. Water absorption value ofless than 20% brick for brick made of mud above 20% thus require immersion in water beforeinstallation. While the percentage of 0%, 10%, 15%, water absorption value of less than 20% brick,the brick does not require installation submersion.

Abstract

Consumption of wheat flour in our country from year to year continue to increase. Ironicallyuntil now wheat flour as raw material still completely imports. In 2007 imports of wheat has reached4.4 million tons. So for those reasons, it is necessary to substitution of wheat flour with other flourof tubers are widely planted by our society. One source of potential tubers is starch that can beprocessed into starch. The major problem of tapioca flour has no gluten so is relatively difficult toexpand. For those reasons, need modification of starch.The general objective of this research is to find a method of starch synthesis of lactate byphysical and chemical characteristics of wheat flour-like characteristics. The specific objective ofthis research is to improve the physical and chemical characteristics of starch so that it hascharacteristics that resemble the characteristics of wheat flour. The results showed that thefermentation for 12 hours to 60 hours of power a real influence on the development of the flourproduced kasava. Additionally, improvement of physical and chemical properties of flour kasavaresult of natural fermentation treatment. This allows a variety of products can be made using rawmaterials from kasava flour fermentation. While the cake flour produced from the fermentationkasava not much different from the cakes made from flour or it can be said nearly matching thequality of wheat flour.
