<![CDATA[The main problem that occurs in most ultrasonic welding processes on ABS thermoplastic materials using ultrasonic welding machines is improper parameter selection. Selection of incorrect parameters will cause various defects in the product such as gaps, dent, offside etc. One parameter that is very influential on the results of welds is the weld time parameter, it is because this parameter has a high level of sensitivity to the welding results. That is why the purpose of this research itself is to test the effect of weld time on the product produced by welding five different parameters starting from the minimum of 0.190s to the maximum parameter of 0.350s by using 15 samples that are available for later testing. parameters using 3 product samples to get maximum results. Then the inspection method used to determine the effect of the weld time parameter is the first air leak testing using a water leakage tester to ensure the weld results on the product there are no leaks and the second method is visual inspection assisted with a tool called luxo lamp, this tool is in the form of a magnifying glass illuminated lights so that we can easily ascertain what defects occur in the product after welding. The results of the data from this study are expected to indicate whether there is a significant influence of the weld time parameters on defects that occur in the product so that it can help companies overcome the problems that occur.]]>

<![CDATA[The need for digitally scanned documents has become a public need these days. Furthermore, smartphone usage with supporting applications to scan barcodes and documents digitally has become a trend. The problem that often occurs when scanning documents is the instability of the hand-held document. In addition, the 3-axis coordinate determination of a smartphone is also not easy to control. Therefore, tools are needed to speed up and simplify the scanning process. This research aims to create a tool that can increase work productivity when scanning documents using a smartphone. Market analysis, engineering planning, and prototypes have been carried out to learn what will decide mass production and sale in general. The data analysis method used a full factorial design, using gender as a factor and preparation time and data scanning time as levels. The initial preparation time to retrieve photo and PDF documents from the initial preparation and scanning results on average takes 4.357 minutes with Std. Deviation 1.739 minutes. As for the following scan with the same paper size, it only takes 1.242 minutes with Std. Deviation 0.201 minutes. The production cost of this prototype is 126.22USD with Std.Deviation 11.36USD. Even though the production cost is the highest, it has a TKDN value of 100% and the application of PBL by students who can carry it out well.]]>
