We have been successfully to create a Control System Temperature and Air Humidy Monitoring Room Based on Arduino Uno with DHT22 Sensor and Passive Infrared (PIR). DHT22 Sensor be used as a measurement of temperature and air humidity in the room and Passive Infrared Sensor as a tool of detection the movement of people in a room. In this experiment, carried out tests of the DHT22 sensor and digital thermometer with a type AZ-HT-02 to room temperature with a hot air given through a hairdryer for 3 minutes with a span of per 10 seconds. In this test, the obtained data is that the room temperature is which measured by DHT22 sensor have an average difference of 0.93 against digital thermometer (as a calibration). In this test also obtained DHT22 sensor more sensitive Rrelative Humidity (RH), this is caused when given the hot air, humidity measured more rapid adjustment and yet different with digital temperature was slow to adjust air humidity in the room. This device using an Arduino Uno board, a Liquid Crystal Display (LCD) module and Real Time Clock (RTC) as a display of the temperature and air humidity in real time. This device is connected to a fan that can stabilize the room temperature are considered less convient to do activities in the room.

Pressure transient of oil in reservoir can be obtained from the solution diffusivity equation. To find a solution of this diffusivity equation takes two boundary conditions as space dimension and one dimension of the initial state as a condition for the time dimension. The solution is determined by using the Laplace transform and then used as a test analysis of pressure drop in a flow test (Pressure Drawdown Test) and Pressure buildup Test. The plot of the solution used to prediction reservoir parameters such as permeability, skin faktor , volume of the reservoir, Dietz Shape faktor and the average pressure. Keywords: diffusion equation, the pressure transient, the drawdown-buildup.

On the other hand, Hexacopter utilizing Genetic Algorithm type A* aims to determine the shortest path is most likely, from a start position to a final desired location. Some obstacles will be registered on the color histogram algorithm as a detection technique, then A* will utilize the position of the obstacles to recalculate the most optimal path so that another drone move without bumping into obstacles. Movement control drone utilizing proportional, integral and differential simple known as PID. The determination of the constants in the PID control drone applications utilize auto-tuning of the mission planner.

The obstacles placed in the position of 1.5 meters above the floor so that the image processing is projected to virtual grids. The position of the projected results become inputs A* to calculate the trajectory. The next stage of testing will also be done on the outside of the building space with the use of GPS in lieu of the grid in question. The results of this study reported how the drones will act with the implementation of the intelligence to control a semi-automatic movement. Keywords: Design , Hexacopter , Genetic Algorithm A* , the shortest path and control hexacopter .

Kebutuhan alat survai geofisika sangat tinggi, terutama alat geolistrik. Tinggi kebutuhan tersebut membuat alat geolistrik menjadi sangat mahal. Untuk memecahkan masalah tersebut, maka muncul ide pembuatan geolistrik. Alat geolistrik adalah suatu alat geofisika untuk mengetahui aliran arus listrik kedalam tanah. Alat geolistrik menginjeksikan arus listrik tegangan DC. Kemudian di dalam tanah akan meimbulkan bedapotensial, bedapotensial tersebut kemudian diukur memgunakan voltmeter. Pada pembuatan geolistrik dimana tengangan DC yang diperoleh dari power supplay. Power supplay yang digunakan berbasis PWM (pulse-width modulation). Prinsip dasar dari PWM adalah menaikan tegangan DC dengan teknik modulasi. Teknik PWN banyak digunakan sebagai penguat amplifier karena memberikan tegangan DC dan arus DC yang cukup besar. Pengunaan PWM tersebut kemudian diubah menjadi power supllay geolistrik karena alat geolistrik memerlukan tegangan DC yang cukup besar untuk memijeksi arus ke dalam tanah pada bentangan yang cukup panjang. Kata-kata kunci: Geolistrik, Power Supplay, PWM, Tegangan DC.

Screen Mesh is a filter made of wire that serves to remove the fine vortex structure by equating the speed variation of wind flow in the wind tunnel. Adding the screen mesh is to determine the effect of screen mesh to the value of turbulence intensity on open circuit wind tunnel. In this study, it has been made three pieces of screen mesh with each diameter of 46.5 cm, 48.5 cm and 50.5 cm. The tests was carried out by using screen mesh with rhombic mesh with 3 mm diagonal length that placed on X/L 0.67, 0.8, and 0.93. This research was conducted by comparing the results of turbulence intensity measurements between the wind tunnel without screen mesh, wind tunnel with honeycomb and screen mesh, as well as wind tunnel with only screen mesh so that we can know the flow quality in the wind tunnel. The test results indicated that the screen mesh has the ability to minimize the turbulence intensity. The wind tunnel that is installed using a honeycomb cell has 6 mm diameter and the 3 pieces of screen mesh has the lowest turbulence intensity that is I â‰ˆ 0,0242. Keywords: wind tunnel, screen mesh, turbulence intensity.

In order to have a DC-DC buck boost converter with performances as desired specifications, the design process was performed by developing a model and simulation. The purpose of this research was to design a converter applied for a MINI 3 plus Wind Turbine. The converter topology was designed with Single Ended Primary Inductor Converter (SEPIC) using a Continuous Conduction Mode (CCM). The output specifications of converter are input voltage 60 V, input current 7,5 A, output voltage 25 V, output current 4,17 A, and frequency 25kHz. The average state space method was used to obtain its transfer function. The transfer function represented the characteristics of an average state of SEPIC converter system. The characteristics and designed quality of SEPIC converter determined by system performance analysis. The results showed that as designed SEPIC converter achieved excellent performances and stability based on their overshoot, rise time, settling time, frequency, and location of pole-zeros. Incontrast, the designed SEPIC converter showed that converter increased the input voltage (boost mode) with duty cycle more than 50% and reduced voltage (buck mode) with duty cycle less than 50%. It was concluded that the designed converter system achieved excellent and stable performances. Keywords: SEPIC converter, state space analysis, transfer function, DC-DC converter.

This study was conducted to determine the gravitational field of the Earth's surface anomaly (g) due to the partial solar eclipse. Large gravity field of Earth's surface can be obtained using a pendulum swing period. Data were collected for three days on 8, 9, and 10 March, 2016 from at 6:00 to 9:00 pm in Bandung with coordinates 6Â°51'48 " LS, 107Â°35'40" BT. The tools used in this research was Kater's reversible pendulum with a deviation of less than 3Â° so that the motion can be regarded swing harmonics. Pendulum swinging motion is recorded using high resolution cameras (High definition) with a shooting speed 24 of frames per second (fps), the video is analyzed using the tracker in order to obtain the period of a pendulum swing. The results show the value of the gravitational field of the Earth's surface on a three-day consecutive sampling of 10,33153834, 10,18560435, and 10,32046468.
