Abstract

The ideal room temperature will create comfort in the learning and teaching process. With increasing outdoor air temperature due to climate change, an air conditioner is needed to reach the ideal room temperature. An air conditioner is an air conditioner that is needed to regulate the temperature and humidity of the air in a room. The purpose of this study is to determine the airflow pattern produced by air conditioning equipment and to determine the distribution of air temperature in the computer laboratory room. Computational Fluid Dynamic (CFD) is a simulation method used by using the ANSYS application. Based on research conducted in a computer laboratory room which has a length of 12 m, a width of 12 m, a chamfer of 3.93 m and a height of 3 m, the airflow pattern produced by the air conditioner is relatively the same between the variable air velocity 2.5 m / s and 3 m / s. Where the air will move straight in accordance with the outlet shape of the air conditioner and then experience a decrease in speed over a certain distance and a change in the direction of air flow occurs due to exposure to room properties and eventually spreads throughout the room. The average temperature in the computer laboratory room for the variable air velocity 2.5 m/s is 24 ° C. Meanwhile, the variable air velocity 3 m/s 23 ° C.

Abstract

A large number of requests for internet access causes a long response time resulting in an overload problem. This problem occurs in offices that provide public services such as the Soeman HS Regional Library and Archives Office in Riau Province. So that service work is not disrupted due to overload, network optimization is carried out using Load Balancing Techniques. Load Balancing will balance load traffic on two or more connection lines so that traffic can run optimally. The method used is the Peer Connection Classifier (PCC). This method will divide the load based on the source, destination address, and port address. All internet requests from users will go to the router that has been configured with Load Balancing with the PCC method. The router will manage outgoing requests from users through the Internet Service Provider 1 (ISP 1) line or ISP line 2 to be able to enter the internet connection. The test results show equal distribution of outgoing access to ISP 1 and ISP 2 lines so that there is no overload on any ISP lines. This configuration will be applied to the Mikrotik router using the Winbox application.

Abstract

The use of solar panels through the Photovoltaic (PV) process is an efficient way to produce electrical energy. The main barriers to the use of solar panels are their low energy conversion efficiency and high initial costs. Solar panels are unregulated DC power sources that produce fluctuating voltages and currents, so they must be controlled properly in order to work as expected. Usually when solar panels are directly connected to a load, the operating point is rarely at its Maximum Power Point (MPP). Maximum Power Point Tracking (MPPT) is used to generate maximum power from solar panels. The DC to DC conversion functions as an intermediary for the solar panels and the load to deliver the maximum power to the load. In this study, MPPT was used with the Perturb & Observe (P&O) algorithm and DC to DC converter with a buck-boost converter type. Based on the test results between simulation and tool implementation, the input voltage of 17.6 V produces an output voltage of approximately 14.4 V for charging a 12 V battery with the maximum power produced by the PV generator. Based on these tests, it can be concluded that the buck-boost converter design based on the Arduino Uno in the 8x10 Wp photovoltaic power plant can work well.
