There are many benefits of using information technology in the health sector such as to make hospital information system, clinic or puskesmas. Now, queuing reservation system is still done manually or just using SMS / by phone, required a system that can be used patient to find and do doctor reservation. Thus, the patient when it comes can be directly checked without having to wait for a long time. Another problem when someone goes to a new area, then need medical services as soon as possible because of that is needed an application which contains information of doctor / clinic nearby. Therefore, in this paper will be discussed draft doctor reservation application by displaying a list of doctors. So the patient simply open the application and will be displayed a list of doctors, this will certainly facilitate the patient in finding and make a doctor reservation.

Iron is chosen for the manufacture of air batteries because it is cheap, widely available in nature. One solution currently being developed is the creation of air batteries. This study aims to determine the effect of electrolyte of seawater and the temperature of air that is in direct contact with carbon cathodes and iron anodes of air batteries as a source of electrical energy.The method used in the voltaic cell which is an electrolyte, anode and cathode solution. It is this anode and cathode that causes a reduction and oxidation reaction, as well as an electrolyte as a conduit to produce electrical energy from chemical reactions. The higher the temperature of the air in contact with the battery will reduce the battery's electrical power.The decreasing air density will reduce the amount of air mass, so that the air mass that is in direct contact with the electrode gets less.

So far, the rural population of fuel users make firewood stoves from ground or cement. Often waiting is made less efficient and produces a lot of smoke pollution, especially if the level of dryness of the wood is low. From this background, then came the idea for the manufacture of stoves that save fuel wood and minimal smoke pollution. Furthermore, to be able to achieve this goal, in this study a biomass furnace will be developed that has a combustion air regulation system and a firewood drying system before use. Research implementation is divided into furnace design (design and fabrication) and testing (combustion characteristics and performance). Research begins with the design of the dimensions and shape of the furnace to be made. Furthermore, fabrication of stoves from Stainless Steel plate materials will be carried out at the Mechanical Technology Laboratory, IST AKPRIND. The stove produced by the construction will be tested with fuel wood in terms of combustion characteristics and performance. The results show that biomass stoves can be used and produced for household and small-scale industries.

Improved a quadrotor technology that is capable of fast maneuvering requires accurate attitude estimation or navigation to maintain a quadrotor stability. The GPS can provide position measurements with an accuracy of several meters, but cannot provide orientation information directly. This study aims to design a quadrotor attitude navigation system based on IMU sensors on AR Drone 2.0 with a Kalman filter using the equation of state space model. The system model was developed using the Matlab software. The Kalman filter is designed as an estimator to reduce noise on the sensor so that it can improve measurement accuracy. The test results showed that the system model can be used to estimated the orientation angle and shift of the quadrotor, while the Kalman filter that designed can reduce noise in the sensor data. At the time of tested, the system provided the measurement accuracy of above 90% when tested indoor.

Most of the black tea production in Pagilaran Batang Production Unit is to meet the demands of consumers from abroad. Because of the abundant requests from abroad, the quality of black tea product must be always controlled, therefore it is necessary to conduct a Multiple Linear Regression Analysis of the tea shoots to find out the most affecting factor of the tea shoots quality so that the quality of contributing factors of highest First Grade black tea product can be identified. The methods used in this study was Multiple Linear Regression Analysis and Multivariate Analysis where the Multivariate Analysis was the Factor Analysis. In addition to determine the regression equation, classical assumption test calculations (normality test and heteroscedasticity test), correlation coefficient, determination coefficient, F hypothesis test and t hypothesis test were administered to find the most affecting factor of the tea shoots quality. From the results of the analysis and discussion on the calculation of multiple linier regression in each garden (y1, y2, y3) it was obtained that the most affecting factor was fertilizer with a value in Afdeling Pagilaran (y1) of – 1415,934 , Afdeling Andongsili (y2) of – 265,858 and Afdeling Kayulandak (y3) of 225,589. Then on the calculation of multiple linier regression in each garden (y1, y2, y3) after summarizing the variables it was obtained that the most affecting factors in Afdeling Pagilaran (y1) was a Trip Pest with a value of - 53,741 , Afdeling Andongsili (y2) was fertilizer with a value of - 46,301 and Afdeling Kayulandak (y3) was fertilizer with a value of 213,073
