<![CDATA[The internet is one of the most popular media today by teenagers. Not a few people are very dependent on the internet so that users are addicted, the symptoms of addiction are given the name Internet Addiction. Internet Addiction is defined as a syndrome characterized by spending an enormous amount of time using the internet and not being able to control its use while online. People who show this syndrome will feel anxious, depressed, or empty when not online on the internet. The low awareness of the public about this addiction disorder is a factor in the increasing number of people, especially teenagers, who underestimate this addiction disorder and are often regarded as something natural because in this era it is indeed a time of wide open technology. Therefore there is a need for technology that helps diagnose internet addiction using the Bayes Theorem Method. In the Bayes theorem method, each symptom weight in this disorder is determined by the probability of the results of a survey or questionnaire that has been done previously as much as 50 data. tendency of individuals who are indicated to be addicted to the internet. Bayes' theorem uses a statistical approach to calculate trade offs between different decisions, using the probabilities and values that accompany a decision. The system test shows that the Bayes theorem method has an accuracy rate of 60% to diagnose the level of internet addiction experienced by teenagers..]]>

<![CDATA[Problems in utilizing Quadcopter, either as a hobby or as special needs are still many obstacles or weaknesses such as; plane easy to fall; plane easy hit; the battery is not durable; vulnerable to weather conditions and others. In this regard, Quadcopter's research and development has grown to include weaknesses of existing Quadcopter planes and to improve aircraft facilities and capabilities. In developing the knowledge and information about the Quadcopter aircraft, the data or parameters related to aircraft lift capability factors; fly long; flying high; type of motor used; the type of propeller used; including the sensors and control systems used. Thus, this study was to find the relationship between changes in the BLDC motor voltage source to the rotor angle velocity (ω); Change of rotor speed to wind velocity through rotor (v); change of rotor speed to rotor lift (Ft); change of wind speed to rotor lift; push the following rotor (Ct). In this study, empirical testing was conducted in the laboratory to determine the relationship among others: changes in the BLDC motor voltage source to the rotor angle velocity (ω); Change of rotor speed to wind velocity through rotor (v); change of rotor speed to rotor lift (Ft); change of wind speed to rotor lift; push the following rotor (Ct). Test and measurement results data show that; the relationship between lift power generated with rotational speed is not proportional Nonlinearity occurs when the rotor is released from the self and starts pulling the strain gauge when the rotation speed reaches around 65 rps. Once the rotation speed of the rotor is able to reach up to 1.5 Newton lift then the thrust rising trend increasing sharply to the increasing the speed of rotation of the rotor. A special rotor that has BLDC motor specifications such as; 1200 KV, 5 Volt and 30 Ampere; blade with a radius of r 0.12 m; at a temperature of about 27 oC; in the condition there are no other wind currents then obtained thrust (Ct) of 1.732. Keywords: Rotation Speed, Thrust Coefficient, Quadcopter.]]>
