<![CDATA[The future technology of the technology of wireless communication system must be able to serve a multimedia application, included voice, data, and high speed video information. CDMA is one of the communication technology which can be used and have been proved as a technique of multiple access that capable of provide this service requirement. In this system the multicell is analyzed until two tier and the system of multiclass is divided into three classes of traffic which are class 1 for voice, class 2 for data, and class 3 for video services. The analysis of capacity is done according to the effect of variable quality of services, chip rate, bit rate and activity factor. The result show that higker chip rates can maintain the required BER of each information and achieve the user capacity in high traffic condition. However, larger bit rate will decrease total capacity. Furthermore larger activity factor will decrease total capacity of system. So the effect of interference in multi cell system can decrease home cell capacity of offered information traffics.]]>

<![CDATA[Information technology and ielecommunications to the Internet becomes the main priority in the development of world progress. These developments provide new break-through in health care services mobile using mobile IT devices or socalled mobile doctor (m-doctor). M-doctor has some excess capacity for health care services that can be accessed anytime, anywhere, by anyone. The problems that still esist on still on m-doctor is that the lack of hardware and platforms that required by the system design and ease of access. One also needs a special study of each section dealing with the existing m-doctor in order to get comfortable for the user. The aim of this study is to address the issue by using streaming multimedia as content that can offer a more clear and specific infor-mation. Streaming multimedia services m-doctor require internet connection and good access, and also requires capable hardware to enjoy the overall bias with good services by using phones that support streaming multimedia mobile facilities. Expected results of this study is a software-based content cellular WCDMA, and the main target is to design m-doctor with streaming multimedia services.]]>

<![CDATA[In this research analyzes the connection Wideband Code Division Multiple Access (WCDMA) for uplink and downlink with imperfect sectorization. Because all channels are on the same frequency, so when the active user increases, the performance of system will decrease. In other words, it causes the capacity of system will decrease. In CDMA terminology, the other frequency of Mobile Station (MS) will get effect to the active MS. The co-channel interference can be decrease with splitting the cell into several sectors. It is called the sectorization. But the sectorization can work well because the antenna radiation can’t make the perfect angle and also there is existance of side lobe of radio frequency. The results show, the imperfect sectoration overlap angle between each neighboring sector decreases the capacity system cause more interference to overlapping sector pair. The knowledge gained is to neduce the large overlap angle and we can make the prediction the loss in cell capacity caused by interference.]]>

<![CDATA[Room server is a room that is used to store server computers and network devices. Room server is important assets for companies or institutions that implement information technology as a support in their daily activities. The importance of that is because in the server room there are applications and databases that store all important and valuable information for the company or institution concerned, therefore the server room must always be in good condition. Design of temperature and humidity monitoring systemsis designed to detect changes in temperature and humidity in the room using ESP8266 Node MCU as the main control, then use DHT 11 as a temperature and humidity detection sensor, then the data will be sent to the Telegram application already installed on the smartphone and displayed in the LCD. If the MQ-2 gas sensor detects a smoke greater than 500 ppm, the buzzer active. With this tool, it is expected to be able to monitor the real time room temperature and humidity in the server room so that it can reduce the damage to the hard drive or other damage.]]>

<![CDATA[Storage box has an important function which is often used to store valuables. In general, the locking system in a storage box is still conventional or manual, making it less practical. In addition, the level of security of the storage box must also be good. As a solution to both of the above, then it is necessary to design an electronic lock system in the storage box by using Electronic Identity Card (E-KTP) as the key access. In the E-KTP embedded chip that contains data that is different from one another. So, with these differences E-KTP can be used as a key. This electronic key system utilizes Radio Frequency Identification (RFID) technology, E-KTP as RFID tags, and Arduino Nano microcontroller. The UID (unique identity) data on the E-KTP will be read by the MFRC522 RFID reader. The data is then used as identification of certain E-KTPs that can be used to access electronic keys (in the form of DC solenoids) in the storage box. The results of the system control and output are in accordance with the plan. The E-KTP registered in the system can be used to access the storage box key. The voltage on the power supply and the Arduino Nano is in accordance with the requirements and in the test, the voltage error is not more than 10%, the MFRC522 RFID Reader is able to read the UID E-KTP data with reading distance 0 mm - 2 mm.]]>

<![CDATA[The heart is a human organ that has a vital function. Small flaws in the heart organ can have a big effect on our body. In general, our heart beats around 60-100 times in one minute. If you exceed 100 times and less than 60 times every minute means your heart is experiencing an abnormal beat. Because some patients who suffer from heart need the automation of early detection. The development of electronic technology makes it possible for heart examinations to be carried out by the patient himself. This research aims to design and build a device to monitor heart rate using a microcontroller. Noise suppression on the ECG signal, heart rate data that has been detected and processed will be compared with normal and abnormal values ​​of the heartbeat. Furthermore, the microcontroller will determine how the heart condition is detected. From the results of the study the heart rate monitoring system using a microcontroller input voltage of 3.7 V DC was changed by the step up module to 5 V DC with a magnitude of error percentage of 0.863% and a charger module used to charge batteries with 4.2 V DC voltage and the magnitude of the error percentage amounted to 0.119%. The amped pulse sensor has an output voltage value of 2.4 V when it is relaxed and 2.6 V when it is beat, and this sensor has a constant and significant output voltage value in accordance with the rhythm of the heartbeat. The heart rate monitoring tool that is made can measure accurately and precisely, because it has a fairly small average error value of 1,727%.]]>
