A design of a cocoa bean sorting machine
Get PDFCocoa plantations have employed thousands of farmer families throughout Indonesia, as well as have been the third largest export among the plantation sub-sector after rubber and oil palm. Therefore, the potential for the development of the cocoa industry as one of the drivers of growth and income distribution is very open. Cocoa bean production in Indonesia continues to increase, but the quality produced is still diverse such as less fermented, not dry enough, uniform bean size, high skin content, high acidity, and very diverse flavors. In this research, efforts to overcome these problems are accomplished by designing a cocoa bean sorting machine that can separate clean cocoa beans and root debris from cocoa beans so as it is expected to make it easier for cocoa farmers, workers, entrepreneurs and industries to more easily get a cocoa bean sorting machine so that the quality of cocoa beans improves and their selling price increases. Seeing these challenges, the authors took the initiative to create a new design a cocoa bean sorting machine with a simpler and more precise design

Get PDF
In the petroleum industry, Enhanced Oil Recovery (EOR) technology has been developed to obtain increased oil recovery from reservoirs. One of the EOR methods is chemical EOR using a surfactant known as the surfactant flooding method. Surfactants have the ability to reduce the interfacial tension between oil and water in the rock matrix so that residual oil can be produced. There are several parameters that affect the performance of surfactants, among which will be discussed in this discussion, namely the middle phase emulsion obtained from the phase behavior test and the results from the Interfacial Tension (IFT) test. Based on the literature review, the method used in IFT uses the spinning drop method. Compatibility test of Fir wood SLS surfactant solution used with a concentration of 0.5% - 3% and a salinity of 4,000 - 110,000 ppm
