Abstract— PT. Asuransi Bangun Askrida has many rooms where each room has lighting in every room. The lighting uses a lot of lights using a switch in every lamp and. Of course it will take a lot of time to control the room lights if you still use the manual method. In addition, manual switch control cannot save electrical energy. We only need to use electricity when needed. But sometimes it is this small thing that is often neglected by the company or its employees. For example, the room lights, companies or employees sometimes neglect to turn off the room lights, even though they are not in the room and sometimes the room is locked by the manager who has important documents. Based on these problems, the researchers are interested in designing and building a room light control system at PT. Asuransi Bangun Askrida which allows to control these lights using a smartphone. With the existence of a light control system at PT. ASURANSI BANGUN ASKRIDA based on android, it can make it easier for security officers to control lights from an ideal distance. Room light control system that has been tested and is running well.

Department of Communication studies UIN SUSKA Riau, Indonesia currently applies the selected of interest (concentration) to students aimed at directed stu-dents to more focus on certain courses based on their interests and academic abili-ties. The concentration that exist in the Department of Communication stuides are public relations, broadcasting and journalistic. Determination of concentration se-lection is carried out by the head of the department. However, to select the right concentration for students, Department have several problems in selection the concentration process. This is because students’ data and value of courses must be classified first, then by conducting an interview to determine the level of stu-dent interest. So that with this process requires a long time. For this reason, a system that can help the selection process of concentration is needed. In the datamining, there is a classification to allow users to group data based on their class. In this study classification will used the Modified K-Nearest Neighbor (MKNN) algorithm. In this study, the parameters used are the values of 6 courses namely introduction to public relations, introduction to journalism, the basics of broadcasting, news writing, mass communication and advertising and the interest of the students concerned. The test was carried out on a concentration classifica-tion system that had been built using confusion matrix. Confusion matrix results obtained are the highest accuracy in the 90% data training scenario and 10% data test with k = 2 and k = 3 values that is equal to 78.08%.

The cause of the leak was caused by a hose that was no longer suitable for use in order to cause gas leakage that could have an effect on the LPG gas cylinder explosion. By making an alarm-and SMS-based LPG gas protection device with a MQ-6 sensor, users can see the leak in LPG gas. When this tool operates when a gas leak occurs, the MQ-6 has a leak in the LPG gas hose, so the alarm will sound. When active, the voice sends a command to Arduino to close the LPG gas valve. Then the alarm sends a command to the user via SMS to inform you that "gas leak has occurred" The implementation of this system is helpful so that users can easily see the gas leak so that they can take measures to combust on the gas stove. In this case, the desison tree algorithm will be used in which the internal node tester checks the attribute, each branch of the argument, and the study node class or class distribution leaf. After research, the results obtained are to generate a precision value of 90 per cent, a precision value of 100 per cent and an AUC value of 0.5 with a very good classification value (very good classification) on the PIR sensor and MQ-6. On the basis of these findings, it can be denied that the use of the yahoo sesison tree can be used in an acceptable and reliable manner.
