    Tulisan ini akan membahas manfaat thermo electric cooling sebagai pendingin dengan dukungan Mikrokontroler sebagai pengendali otomatis. Rancangan dapat dimanfaatkan pada sistem pengendalian peralatan, kinerja sistem terpengaruh panas, sistem-sistem lain yang berbaya jika bekerja pada suhu tinggi, serta dikendalikan dari jarak jauh. Kebutuhan perangkat keras rancangan ini adalah thermo electric cooling, Mikrokontroler AT89C51, IC LM 35, A/D Converter, penampil, dan Regulator 7805 serta didukung bahasa Assembler earth.asm. Sebelum perancangan dilaksanakan pengujian peralatan-peralatan, supaya sistem dapat berjalan dengan baik dan sesuai dengan fungsinya masing-masing. Untuk mengetahui kinerja system pendingin ini dengan cara mengamati data hasil simulasi pada tiga keadaan kondisi suhu prosesor dan heatsink prosesor pertama menggunakan heatsink standar, kedua water block dan ketiga water block ditambah thermo electric cooling. Dari hasil grafik menunjukkan bahwa system pendingin thermo electric cooling paling efektif dibandingkan dengan heatsink dan water block.Dengan melihan hasil tersebut rancangan pendingin berbasis mikrokontroler ini dapat sebagai tambahan pengetahuan bahkan dapat dikembangkan untuk memenuhi kebutuhan dan mengatasi permasalahan data/informasi yang banyak dibutuhkan

    GPS (Global Positioning System) is a system used for navigation and positioning with the help of 32 satellites that orbit the earth. GPS satellites emit radio waves to activate the GPS receiver on the Earth to determine the exact location, speed and time for all weather conditions. Currently, GPS has a vital role in navigation drone. However GPS have a lot of noise, it is necessary to overcome the noise filter on the GPS. In this research conducted a simulation of adaptive algorithm in extracting data from the GPS sensor. The method in this research is the Kalman Filter. From the identification and simulation can be concluded that the adaptive algorithm is designed to work well and need to be implemented on the downlink system. The simulation results showed that the error of algorithm has convergent properties are increasingly shrinking

    The increasing demand for the utilize services computer networks has increased the traffic on the network. In general, the server provides service round the clock without a break, so that problems such as breakdown of communication in the network is lost that must be avoided. This cases need for a bettersystem with high performance and reliable every time. Current server technology development will be fast but the memory access speed is slower than the increase in the consumption of bandwidth. This is one o f the factors causing the bottleneck experienced of server. With the load balancing can be provide abetter solution. The concept used to provide a server has the same service. Then, the load balancing will check the CPU USAge on each server. The server will perform selection based on the value of the smallest CPU Usage o f all existing servers. The application load balancing is placed before the user accessing ofserver with the object of distributing requests from the user to any of the servers that have been selected by the load balancer. Load balancing provides many benefits to systems that use it. The first, low cost, existing resources do not need to be replaced or discarded. Second, don't always need high end equipment. Third, easily developed when needed arose and a drastic decline in the quality o f service. Load balancing is also more secure, when a failure occurs on the server, load balancing application will redirect the user to the server is still available

    Development of the world\u27s information and communication technology-based growing rapidly. The development of these technologies has given rise to another dimension in human life, namely the need for computer use. Application of machine vision applications where a computer has the ability to understand the data in the form of image and make decisions based on data obtained from a real object, in this case is generated through the capture image from webcam. The images (digital images) of a real object through a webcam can be done in many ways capture the object. In this research object retrieval using an object of activity is captured on the webcam through the motions of objects. Digital image acquisition is performed with the tool in the form of software (Obtion Remote Version 1.0). Obtion (Object Detection) method works with the system of comparison between that time frame the previous frame captured by the camera at the time of recording the object. Comparison of the difference in the frame will be accommodated in a place that will be used to support the execution of an object by counting the number of pixels that exceed the value of the difference in number of field values with regulator frame to frame changes in the location of the object motionObtion Remote Version 1.0 will take a digital image of the object with trigger object motion detection performed. Digital image acquisition (capture the object with a webcam) will be done automatically if the object has been successfully detected. The detected object will be stored automatically in the directory are executed as a digital image storage

    The growth of the web services make people tend to think far ahead to discover new things on this technology. Increasing development and evolution of the various developments. Web service is one of media that suitable for system and platform communication, this service is considered as an efficient and effective communication facility. Web service make a system communication connected with Internet.The system is built with a proper analysis and effective design to help human to communicate each other. The design from start to end, is useful to help in writing the command of blogs which has a lot of comments. The comments that belong to many website/blogs is recorder into one report so that make the review become easier. It also can maximize the quality and the quantity of the website / blog.System is designed to facilitate the manager of the website/blog, especially in the pe-an-record comments entered. Manager of the website / blog just need to provide a form which connected to the database as a means of data entry comments

    Software design and hardware application system monitoring room webcam based aims to add value to the webcam to be used as part of the security system, implementing the work process of hardware and software monitoring system formed using delphi 7, analyzing the performance o f a stepper motor as the driving platform webcam and documenting object images and sounds in the room activities into a file format AVI (Audio Video Interleave). Webcams are used in this design is equipped with a standard webcam lighting lamps LED (Light Emitting Diode) with a USB data line, while the driver controls the webcam in the design o f this platform using unipolar type stepper motor controlled by a microcontroller, motor drivers and line interface RS232 to USB (Universal Serial Bus) converter. The installation o f the webcam to webcam platform play will lead to the right, left, stop rotating right and or to the left automatically. From the test results it can be concluded that the monitoring system and webcam based indoor stepper motor consists o f webcam applications and motor control applications platform which is separately because both applications use the USB and COM communication channels are opened simultaneously. As for the results o f the motion setting webcam platform proved to have a consistent degree of deviation for the wine and left turn kenanan but still require a series o f additional gears for smooth movement o f the platform and to reduce the effects o f shadow on motion pictures
