Abstract

The increasing of rat population in the environment around us, will cause anxiety, both due to mouse droppings that can be scattered everywhere even in corners of the room that are not visible to us, This will certainly make us very uncomfortable and will certainly cause various kinds of diseases because of the dirty environment.  the impact of rats is that can also cause household appliances such as clothes, cables, and other important items to be damaged due to the rat's act. This will certainly make us very uncomfortable, many of people try various ways may have been done to be able to completely eradicate these rats, but in reality, rats will never completely lost from our lives, we can only prevent these rats from entering our homes. Therefore, we try to assemble and create a tool that can repel or minimize the presence of rats in the house, by utilizing technology. The modern technology that we convey here is Short Message technology or SMS. SMS here is used to inform us about the presence of mice that may intend to enter the house. This of course will make it very easy for device users if they are away from home.

Abstract

This research aims to know the value of viscosity coefficient on the four cooking oil samples carried out by the video analysis using software tracker and comparing the viscosity coefficient value obtained with the viscosity coefficient value from the previous research. Determination of the viscosity coefficient of cooking oil using the falling ball mehod using a 1000ml glass tube and using marbles as solid balls. A recording is started when falling marbles from the oil surface and stops when marbles arrive on the tube base. Then, a video that was obtained was entered into a software tracker for the next step to retrieve time and distance data. Based on analysis and calculations, the study can be concluded that the viscosity coefficient value in the four cooking oil samples is brand 1 of (0.4602 ± 0.0930) Pa.s; brand 2 of (0.4246 ± 0.08665) Pa.s; brand 3 of (0.4231 ± 0.08652) Pa.s; and brand 4 of (0.4199 ± 0.08738) Pa.s.
