Abstract

Technological developments are so rapid in various fields, one of which is in the field of education. Nowadays we can get information, news, knowledge with the internet. In education, increasing knowledge is very important, with the internet we can get the latest scientific knowledge information from journals, modules, digital books from various parts of the world with just a gatget or laptop. To support these activities, it must be with good technology infrastructure, if the ratio between users and infrastructure is not balanced, conges will occur, where the available bandwidth cannot cover users who are connected to the internet, resulting in slow connections. Currently the WIFI network infrastructure at the University of 17 August 1945 Cirebon needs additional access points and additional bandwidth, because when user is connected to WIFI network increase conges occur, and there are several places that are far from the access point location. in network design there are two modeling were used that calculation of bandwidth capacity based on the number of users with three scenarios aksess speed of 0.5 Mbps, 1 Mbps, 2 Mbps and spacious area. The results obtained from modeling based on user capacity, the required access speed of 141.2 Mbps, 282 Mbps and 565 Mbps.The results obtained are calculated based on the user's capacity, the number of access points is 25 Ap and 14 Ap on the calculation based on the area.

Abstract

Automatic monitoring and control technology in chicken coops can be useful for broiler breeders in carrying out their daily farming activities. Monitoring data on environmental conditions in the cage can be done remotely with the help of the internet, as well as automatic control to maintain the stability of ideal conditions in the cage can be controlled based on the reading value of the current condition of the cage. The purpose of this research is to make it easier for breeders to carry out monitoring activities and regulate the stability of environmental conditions in the cage automatically with the help of internet of things technology. The stages of the research carried out were designing a chicken coop prototype and conducting control trials based on sensor reading values and designing a website for real-time data monitoring interfaces. The data obtained from this study were in the form of temperature, humidity and ammonia values in the cage. The research results for data monitoring show changing values during one week of monitoring. With this research, if it is further developed, it is hoped that it can regulate the ideal environmental conditions of the coop so that it can be maintained and the growth of the chickens can be more optimal.

Abstract

Three-phase induction motors are the most widely used type of motor in industry, induction motors are widely used as prime movers to turn loads on production machines in the industrial world. The output of a three-phase induction motor is the amount of torque to move the load. If the load torque carried by the three-phase induction motor is greater, then the three-phase induction motor will not rotate. And if the load torque carried by a three-phase induction motor is too small, this is considered excessive. In this analysis the method used by the author is the experimental method of analysis using the Power Simulator application with load data and induction motor data. Based on the analysis, it was found that Istart and Inominal on a 15 kW induction motor have different values ​​according to the torque value used, so the torque value is directly proportional to the Istart value. Meanwhile, Istart induction motors 15 kW 894.324 (15 N.m), 894.149 (25 N.m), 894.159 (60 N.m) and 45 kW induction motors 355.15 (25 N.m), 355.172 (60 N.m), 355.172 (80 N.m) and induction motors 55 kW 337.743 (30N.m), 337.76 (50N.m) and 337.761 (100N.m) Reaches 80% of full speed, torque is at its highest “pull-out torque”) and current starts to fall and is at full speed, or synchronous speed, torque and stator currents drop to zero, it can be concluded that the greater the value of the stator resistance, the smaller the value of the starting current.

Abstract

Water is a source of life for all living things. However, currently the amount of clean water available is very limited so that it is not comparable with the increasing growth of the world's population. The saving effort that can be done is to make the best use of water. One of them is by saving bath water by controlling the water level in the water reservoir. In this final project, an automatic faucet is designed using an ultrasonic sensor, namely a sensor that will detect the presence of an object and remove or turn off water automatically with the main actuator using a servo motor. In filling the water reservoir to prevent water from overflowing, an ultrasonic sensor is used which will automatically fill when the water volume distance is not within the specified range and will also automatically stop filling when it is within the specified range. So that no more water is wasted due to user negligence.
