<![CDATA[In this paper and has implemented a stethoscope electronic application sound analysis in heart client-server. A stethoscope electronics will catch a heart and menghantarkannya to computer so that the computer can sound mendigitalisasi heart. The application will process, sound analysis heart store and display a heart condition and sound spectrum of the heart. Extraction habitude anything undertaken to gain special habitude from the heart to perform the process of decomposing paket wavelet and root mean square ( rms ) at the sound of the heart. From the data obtained, in different heart conditions, decomposition of wavelet package give value range min 6 up to a maximum of 23 is much larger and RMS only give minimal range 0.04 to 0.16 in band 0-125Hz of variations of the same types of heart conditions. Sample Data obtained from 5 persons recorded sound his heart and then analyzed with the same two methods. The Data obtained are more closer to the normal heart sound so it can be deduced from the 5 sample data used is the sound of the heart under normal conditions.]]>

<![CDATA[The development of online payment systems such as the online payment point system has greatly assisted the public in processing monthly transactions such as water bills. However, in its application, this system still uses large devices such as computers and inkjet printers so that the operation takes a long time and is less efficient. Therefore, in this study, a mobile application is designed to replace the role of computers in making water bill payment transactions in the online payment point system (SOPP) of PDAM Malang Regency. The application that is connected to a database server via the internet is also integrated with a compact wireless thermal printer that can be carried anywhere and does not require ink refills so that it can speed up the transaction process and be more efficient in time, paper and space. The research method used was experimental and survey methods. The experimental method is used to test the running of the application, test the application's compatibility with the device and measure the time it takes for the application to exchange data. The survey method is used to test user satisfaction with the application.]]>

<![CDATA[A doctor or medical scholar needs a reference book to learn how to diagnose tropical diseases. This reference book is sometimes a hassle if you have to carry it everywhere. This reference book is also impractical if you have to search it first to find the symptoms and diseases you want to study. So that we need a system to make it easier for doctors and medical scholars to study the science of diagnosis and look for symptoms and diseases. Expert systems are knowledge-based programs that provide expert quality solutions to problems in a specific domain. This expert system is used in the fields of medicine, agriculture, business, and others. Expert systems in the field of medicine make it easy to identify diseases suffered by patients through the symptoms present in the patient. This expert system helps doctors make diagnoses to convince doctors about the results of the diagnosis. The expert system in this study uses a combined method. The combined method is forward chaining and backward chaining. The forward chaining method is used to determine specific symptoms that appear, while the backward chaining method is used to trace general symptoms that arise from specific symptoms that have been previously selected. The result of combining these methods provides a diagnostic percentage of 100%. Meanwhile, the user's assessment of the system gives a good response.]]>

<![CDATA[The problem that often occurs in VOIP networks using wireless media is the weak signal received and transmitted by the transceiver device at a long distance from the wireless router, so that the quality of VOIP service is often disconnected. The purpose of this research is to design and realize an 11 element yagi antenna with folded feed elements. dipole as an antenna for a transceiver device whose gain is better than a built-in antenna, so that it can support VOIP services. Yagi antenna is an antenna consisting of 3 elements, namely a reflector element, a driven element and a director element. The reflector element and the director element cause the yagi antenna to be directional so that a large gain is obtained from a certain point, while the driven one is used is a folded dipole antenna which has an impedance of 300 ohms so that the matching technique to the 50 ohm transmission line becomes easier. Ghz is less than 1.5 and RL is less than -14 dB. The bandwidth obtained is 620 MHz, the gain is 16.08 dBi with directional radiation and linear polarization. In implementation, the VOIP service is stable at a distance of 50 m using a yagi antenna, compared to the less stable built-in antenna.]]>

<![CDATA[The factors that cause the death of vannamei shrimp seeds include water temperature and acidity of water pH. The need for water temperature for vaname shrimp hatcheries ranges from 28 ° C to 32 ° C and the acidity level of the vaname shrimp hatchery water ranges from 7 to 8.3 . It is difficult to know what changes in water temperature and pH have occurred because there is no technology that can support it. The design offered is in the form of monitoring the temperature and pH of the water in the vaname shrimp hatchery so that it is more effective because it can be done remotely. This application works with a temperature sensor and a pH sensor that reads the temperature and pH of the water in the vaname shrimp hatchery continuously. So, when the temperature and pH change far from normal temperature and pH in the range of 28 ° C to 32 ° C, the read temperature and acidity (pH) will be processed on the microcontroller, then the data from the microcontroller will be sent to the ethernet shield then it will be displayed in the android application. With this application, it is hoped that the owner of the vaname shrimp hatchery can monitor and take action on changes in water temperature and pH that occur continuously. Thus, the possibility of the vaname shrimp seed mortality factor can be reduced.]]>

<![CDATA[HSDPA (High Speed Downlink Packet Access) is the upgrade performance data packets extraordinary against WCDMA thus producing top speed 14,4 Mbps. One of the goals the creation of HSDPA is as an improvement over previous technologies. The expected improvement of HSDPA technology increasing the data rate is capable of exceeding data rate in order to WCDMA customer satisfaction in accessing multimedia content such as streaming video and data at high speed. Data Rate is the maximum data rate that can be accepted by the UE (User Equipment) in ideal conditions. One of the factors that affect the data rate is modulation scheme used by each of the technologies. QPSK modulation is used in WCDMA system and adaptive modulation (QPSK and 16QAM) is used in HSDPA system.In the research the results obtained by selection of symbol rate of 480 kbps bit rate will yield 960 kbps while the selection symbol rate is 960 kbps will produce 1920 kbps bit rate using modulation QPSK modulation. As for 16QAM modulation, symbol rate of 480 kbps produces 1920 kbps and symbol rate is 960 kbps bit rate produces 3840 kbps. Of the trial results, the more number of bits sent then the higher data rate that can be accepted by the UE (user equipment).]]>

<![CDATA[The monitoring program is made running using SMS communication on the GSM network with the aim of its application is to be used to monitor various types of vehicles commonly used by the public as a means of transportation. The GPS that is installed functions as a device that will search for location coordinates in the form of latitude and longitude to be sent to the user. On the user side is given a program that will process any data sent by the GPS device and display it in the form of a digital map as a tool for users to monitor their vehicle.From the test results for the time needed to request the position of the vehicle from the program to the GPS device via SMS, the average time value is 16.11 seconds in each position request. Meanwhile, for testing the accuracy of the vehicle position plot with an average speed of 10km / hour, the difference in distance is +/- 27.5 m, 20km / hour is the difference in the distance +/- 55.1 m, 30km / hour is the difference in the distance +/- 82, 7 m, 40 km / h difference +/- 100.3 m, 50 km / h difference +/- 137.5 m, 60 km / h difference +/- 165.5 m distance, and 70 km / h difference + / -197.1 m.]]>
