<![CDATA[Temperature and air circulation is an important factor in a building since it is closely related to health comfort. Therefore, the design of a building should be carry out precisely in getting a clean, healthy and comfortable air circulation in accordance to the requirement of the room.In order to carried out a good building designing, a research was needed to understand temperature distribution, the pattern of air flow and its velocity. In this research, a Classroom of TN II JTF UGM. This classroom have 1030 cm length, 790 cm of width, and 330 cm of height. The size of the windows is 100 x 100 cm and place 1m from the floor. The size of the doors is 140 x 210 cm. The windows are assumed to be widely open, the door always opened. The researched begins with geometric modeling of the model by using Gambit 2.2.30 and continued with model testing using Fluent 6.2.16. The test is carried out by giving three velocity variation of free air flowing i.e.: from 1.3 m/s, 3.61 m/s and 5.92 m/s, two direction variation of open air flowing and two variation temperature of free air i.e.: 21.50C and 27.650C.The standard of comfortable air velocity used in the room is 0.15 < V < 0.25 m/s, The standard of comfortable temperature used in the room is 20.50C and 27.10C. The air velocity and air temperature variation created comfort area and non comfort area in the room .The direction circulation of air variation created the different pattern air circulation in the room.]]>

<![CDATA[One of the areas that often become a source of traffic jam is road intersection. So it will be crucial to manage the intersection. Every intersection in main road is common to have traffic light and every cycle of the lamp, red, green and orange, will influence the traffic. The traffic cycle will have significant role to decrease or increase effects of the problem. Inappropriate regulation for the intersection can cause traffic jam or a heavy traffic jam in the road. Sometimes every intersection needs different rule based on the traffic condition. Therefore is truly needed to manage the traffic light in every intersection. With the simulation we can know whether the rule for the traffic light has appropriated to the intersection's traffic condition. If the rule is not optimal yet, we can change the rule with the optimal one. In the research, two methods are used, using coupling parameter and without coupling parameter. Average of vehicle Arrival in each intersection is used as coupling parameter. As its result, using coupling parameter is better than without using coupling parameter.]]>

<![CDATA[Heat pump is a device that can be make heat and cool , which is functions as a cooling evaporator can be replaced to be a heating condenser. With adding a heat exchanger in the heat pump can provide better effect of heating and cooling. In this experiment, the heat pump using type hydrocarbon refrigerantand type friendly refrigerant to the environment, one of refrigerant isR-290. From the results that obtained value Coefficient Of Performance (COP) in the heat pump that uses a counter flow heat exchanger is 4.8 while the heat pump that does not use a counterflow heat exchanger obtained COP of 4.1. Efficiencies increase in the heat pump without using counter flow heat exchanger is 74%, otherwise the efficiency decrease of the heat pump using heat pump is 85%.]]>

<![CDATA[Biogas is a renewable energy potential to be developed in Indonesia. It is based on the increase in the number of household-scale biogas reactor. But the number of biogas reactors currently installed is still not equipped with biogas purification system integrated with the biogas storage tank system. Storage of purified biogas on the tube is required to extend the range of the use of biogas in some areas that have been using biogas as an alternative energy source. Storage tank systems require control systems in a storage tube that could biogas storage mechanism accordance with the maximum capacity of the tube used. This system uses a sensor components MPX5700AP and Arduino microcontroller, LCD display to display pressure readings, and solenoid valve as an actuator. The working principle of this pressure control system that is used to read the sensor value changes of pressure in the biogas storage tank A and B to be sent to the Arduino and a subsequently processed data accordance specified set point. Charging conducted alternately pressurized biogas through a method ON / OFF Valve Selenoid 1,2,3 and 4 on each biogas storage tanks. At the testing that was done we got the result response of pressure control system against time on pressure sensors P2 and P3 value rise time (tr) = 15 s, settling time (ts) = 12 s, whereas for pressure sensors P3 obtained values rise time ( tr) = 14 s, settling time (ts) = 12 s. The test results are static characteristics sensor hysteresis error of 0.00078% and 0.90%.]]>

<![CDATA[Effective and efficient is a way to facilitate the public in conducting activities, for example in terms of opening doors that are large, requires a lot of time and energy. Using Arduino, Android and PIR sensors are designed to make a protoype controlling automatic doors are controlled via Android via Bluetooth HC - 06 and can work automatically with the response detected by the PIR sensor. PIR sensors and Arduino serves as an input and as an output stepper motors to open and close the door. The working principle of this automatic door is in an android installed a software to control a door that has two modes. If the manual mode is activated, the door opens only when controlled using Android, when the automatic mode is activated the door will open when the sensor has detected the temperature of the human body that moves the door will open. The maximum distance control door is 1-50 meters in open space , but in a closed space that is controlling the maximum distance of 45 meters.]]>

<![CDATA[Microfluidics devices have been applied in the biomedical field to manipulate the tissue fluids in channels with dimensions between 5-500 lm. Microfluidics device manufactured by a microfabrication process consisting of design, microstucturing and back-end processes. One application of microfluidics is a passive mixing microchannel. In this device, the liquid will flow through the channel without any moving parts and the pressure from the outside to produce a fluid mixing. It is important to design the shape of the channel to generate a nice passive mixing microchannel. Low power CO2 laser is used to process microstucturing as cutting tools to produce microfluidic devices on acyilic material. Surface roughness lines were designed to be observed. In this study, the design process channel carried by the experimental method through the parameters that affect the output of the process is the power of laser cutting, cutting speed and design channel. And then the fabrication of microfluidics with back-end processing is done by the process of merging with a thermal bonding method. Finally, From the experimental results, the design of the channel 1 has an influence on all the parameters for surface roughness compared with a channel design 2.]]>

<![CDATA[Heat source of the heat energy can affected of the temperature distribution and the boiling temperature of the tapering heat pipe located on the evaporator. The purpose of this study was conducted to determine the effect of heat source on the temperature distribution and boiling temperature that occur in the tapering heat pipe. In this study, used heat pipe tapered shape of the copper pipe diameter of 10 mm and 20 mm as evaporator as condenser with a length of 200 mm. Tapering heat pipe inside there is a wick mesh screen serves as the axis of the capillary to the return liquid / backflow of fluid from the condenser to the evaporator. The condenser ends mounted a valve to inject the working fluid into the tapering heat pipe. K-type thermocouple is integrated with NI-9211 module and c-DAQ 9271 to measure the temperature distribution along the tapering heat pipe with a heat source of DC power supply for (25, 30, 35, 40, 45, 50) Watt. The results showed that there was a difference of temperature distribution and boiling temperature caused by the variations heat source. Temperature of distribution and boiling temperature which tends to increase in value the greater the heat source, so it can be concluded that the heat source has an influence on the temperature distribution and the boiling temperature of the tapering heat pipe with 50 Watt heat source generates temperature distribution and boiling temperature stable.]]>
