PT. XX is one of the largest copper company in the world. Chalcopyrite (CuFeS2), bornite (Cu5FeS3) and pyrite (FeS2) are three major minerals in PT. XX is capable to produce about 2000 tons of concentrate per day, with design of processing capacity around 120,000 tonnes per day. To obtain grade Cu concentrates, an integrated method of extraction metallurgy (metal extraction) is usually carried out, so that this study focused on increasing low consentrate grade Cu, using lime and increasing pyrite content using the flotation method by varying pH and varying the dose of sodium metabisulfite. This is indicated by the percentage of Cu grade of 12.74%, the use of lime shows the percentage reduction of 50% and the decrease in pyrite to reach a percentage of 1.16%. Of the three variations of the SMB, namely no reagent, 150 and 300 in this study, 300 is a good dose in increasing grade Cu, reducing lime use and reducing pyrite content.

Plastic is one of the most commonly used materials today. However, the continuous use of plastic has the potential to cause problems in the future. Because, plastic waste takes a very long time to be able to decompose on the ground. If it is dumped on the ground, it will damage groundwater and soil quality. Therefore, plastic waste must be managed properly, so as not to damage the environment. On the other hand, Sumbawa Island is one of the biggest corn-producing islands in Indonesia. It is unfortunate if the waste in the form of corncobs is not utilized properly. In addition to the problem of plastic and corncob waste, Indonesia also has problems with geographic areas. The problem of this research is how to utilize plastic waste and corncob waste into earthquake resistant building blocks. So, it is expected to be able to replace bricks, bricks, or furniture in order to minimize environmental damage. The data needed in this study were obtained from several scientific papers related to this research. From these data then analyzed to obtain the right formula for making composite bricks and testing. Tests conducted on this product are specific gravity, water absorption, and heat resistance. As a comparison, hebel is also included in each test.

Mead is a sweet and thick food containing gold to chocolate with high sugar content and low fat. But mead farmers have a mead squeeze process, because mead farmers in Sumbawa still use traditional methods. Related to this at the time of extortion and comfort of mead farmers. Furthermore, a mead squeezer machine is needed as a solution to improve the work process of mead farmers in producing quality mead water. The press from this automatic mead-squeezer produces mead water that is not mixed with the residue of the residual nest. This extortion process takes a short amount of time to squeeze meadcombs with a capacity of 3 kg in just 10 minutes. At this time meadcomb dregs are stuck to the walls of the filter and do not come mixed with mead water depending on the filter hole which is very small and neat. This extortion process uses an electric motor with a rotation of 1400 RPM as a drive or filter player that is transmitted by the van-belt.
