<![CDATA[Abstract: The size of droplet affects the evaporation of the fuel. The greater the size of droplet is also the energy of fuel evaporation. The evaporation energy is directly proportional to the size of the droplet and oxidation must be mixed homogeneously. Mixing conditions in the combustion process affect the rate of combustion. One of the conditions of combustion is the droplet to the vapor. The more perfect the evaporation process the better the combustion process. This study saw the success of combustion due to the size of droplet on the performance. The droplet produced by atomization in the form of liquid granules. The size of atomization is the determinant of burning success. The four-stroke Otto engine performance depends on the size of the atomization in order to mix well with the oxidant during combustion process. The results of the research characteristic of the machine are due to the influence of the size of the droplet seen from the generated power, torque and thermal efficiency. Characteristic features increase with decreasing the size of the droplet. Torque increased 7.9%, power generated increased 7%, and thermal efficiency increased up to 7.3%. The results of this study show size of the droplet can improve the performance of engine. ]]>

<![CDATA[TFASSIP-02 loop is a test facility that is used for research and development of safety technologies for future nuclear power plants based on natural law. This test facility is designed to study natural circulation phenomena caused by differences in fluid density due to temperature differences in the one-phase heat dissipation system during the simulation of heat removal from the reactor core when an accident occurs. FASSIP-02 loop consists of piping components, water heating tanks, water cooling tanks and expansion tanks. The purpose of this study was to understand the conditions of temperature change and pressure of water working fluid based on temperature changes in the heater section which were simulated on the loop geometry FASSIP-02. The research method was carried out in a simulation of Computational Fluid Dynamics using FLUENT 6.3 software. The working fluid in the FASSIP-02 loop uses water with a temperature of 27°C, the flow rate is varied 0.3 m/s and 0.45 m / s, while the temperature in the heating section is 70°C. CFD simulation results show that the increase in the working fluid temperature of the water with a flow rate of 0.3 m/s after passing through the heating section is 39°C, while the temperature increase of the working fluid of the water with a flow rate of 0.45 m/s is 36.6°C. Pressure drops at flow rates of 0.3 m/s and 0.45 m/s each occur in water working fluid before entering through WHT and after passing through the heating section. ]]>

<![CDATA[Ignition timing in an important at internal combustion. Timing has a role to synchronize the system in order to get optimal energy. Ignition time is directly related to working pressure in the combustion chamber. The delay combustion will result in higher work pressure. Increased work pressure can increase the performance of the fuel motor and can reduce emissions because combustion is encouraged to be more perfect. Various methods can be done to accompany the conditions of delay combustion to increase work pressure by increasing the octane number. This research focuses on the influence of the one-step gasoline engine performance variable. Effective octane enhancing solutions are used to increase pressure with the concept of combustion delay. Octane-enhancing solutions can be used in various types or concentration in fuel. The results of the study are that torque can increase up to 15% and the power can increase up to 20% compared to standard testing conditions. This is effective at medium to high engine speed.]]>

<![CDATA[An apartment is a place to live in a building, equipped with various facilities, and is a public area inhabited by hundreds or even thousands of people. The security system in the apartment is not comfortable and safe, because of the condition of the apartment area that can be accessed by anyone as a fellow occupant (one area but in a different building). Based on the observations that have been made, one solution that can be done is to limit access to the apartment building. This access restriction can be done by dividing the entrance and adding boom barriers in each lane. The method used is a design method based on the results of observations. The design of this system considers the number of lanes, vehicle speed, and distance traveled. The speed used is in the range of 5 km/h and 20 km/h with a maximum distance of 27,081 m and a minimum distance of 9.998 m. The fastest travel time obtained is 1.799 s with a speed of 20 km/h and the slowest is 19.497 s with a speed of 5 km/h.]]>
