COMPARATIVE ANALYSIS OF MAMDANI AND SUGENO'S FUZZY INFERENCE METHOD ON ROOM LIGHT CONTROL PROTOTYPE

Fuzzy Logic can be applied to the field of control systems. The advantage of using Fuzzy Logic is that it is easy to calculate because it combines mathematical equations and natural language. Therefore, Fuzzy Logic overcomes the weakness of the On/Off control system. Likewise, Fuzzy Logic overcomes the complexity of mathematical modeling on PID control. However, Fuzzy Logic is not suitable to be applied to control systems that require high accuracy. In this study, Fuzzy Logic will be applied to the control of room light, where in the room there are two light sources, namely lamp light and outside light. The problem is how the room light illuminance is always in the set point range with a tolerance of 25 lux and in steady state conditions. The application of light control is appropriate because it does not require high accuracy where a slight change in light illuminance has no effect. In this study, a comparison was made between the Mamdani and Sugeno inference methods. The limitation of control parameters is on the response of the control system to the set point. The results obtained are the control system response shows that there is a smaller error in the Sugeno method than the Mamdani method

OPTIMIZATION OF OXYGEN.ID SERVICE WITH THE IMPLEMENTATION OF HIGH AVAILABILITY ROUTER HOTSPOTS AND TRANSPARENT BANDWIDTH MANAGEMENT ROUTERS: A CASE STUDY OF PT. INDONESIAN TELEMATICS MORA

With the increasing demand for public free WIFI hotspot service Oxygen.id causes increased traffic in accessing the free WIFI hotspot Oxygen.id service, which of course can result in decreased access performance for customers. By applying The Virtual Router Redundancy Protocol (VRRP) router method and simple bandwidth management queuing to fix existing problems, an additional load simulation of 1450 bytes was carried out from the PING status on the CMD window, the results found that the VRRP hotspot was still stable compared to the existing hotspot. and at the time of testing the mp4 file download process was 17,555KB. The resulting VRRP hotspot output is 673 kbyte, which is bigger than the existing thinkput hotspot, which is 495 kbyte, while the delay result is smaller for VRRP hotspot 35,422 compared to delaying the existing hotspot, which is 39,693 seconds, with the results of this study proven completion in overcome the traffic of serving the free oxygen.id hotspot wifi which is getting higher and highe
