Sistem navigasi pada pengoperasian pesawat tanpa awak (Micro UAV) saat ini terdapat 2 cara yaitu dengan cara pandangan manual (line of sight) dan sistem autopilot. Sistem navigasi line of sight memiliki kelemahan jangkauan pesawat tanpa awak hanya pada radius 200 meter karena keterbatasan penglihatan dari pengendali. Metode autopilot adalah metode kendali pesawat dengan algoritma lock position and homing. Sistem autopilot bekerja dengan cara mencari koordinat posisi yang dituju kemudian kembali ke lokasi awal. Keunggulan teknologi ini adalah pesawat dapat menjangkau jarak yang cukup jauh. Akan tetapi metode ini memiliki kelemahan yaitu pesawat harus terbang tinggi dan pesawat belum bisa menghindari halangan seperti gedung pencakar langit maupun pepohonan tinggi. Dalam penelitian ini dirancang sebuah sistem tele-navigasi yang merupakan modifikasi sistem navigasi line of sight dan autopilot sehingga dapat menutupi kelemahan dari masing masing metode navigasi yang ada saat ini. metode penelitian yang digunakan dalam penelitian ini adalah metode eksperimen yaitu dengan membuat pilot plan sistem Tele-navigasi yang selanjutnya akan diuji dengan pesawat tanpa awak (micro UAV) jenis flying wing. Metode dokumentasi dan metode studi pustaka juga digunakan untuk melengkapi data teknis alat yang digunakan sehingga dapat dilakukan analisis mendalam terhadap performa alat yang dirancang. Kata kunci: line of sight, lock position and homing, autopilot, micro UAV.

Development of the world's 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.

The increase o f request brings large traffic to networks especially to data centers, large enterprises and portal websites. In addition, server provides more and more information by using applications. Most servers have to provide all-day services, and any service interruption or key data loss in communication will result in business loss. All these require high performance and high reliability on application services. However, the increase of server processing speed and memory access speed is greatly lower than that o f the network bandwidth and applications. In addition, the increase o f network bandwidth makes server resource consumption more serious. Therefore, the servers become the network bottleneck, and the traditional single device mode becomes the network failure point. Load balancing (LB) comes to provide a good solution by providing multiple servers form a server cluster, with each server providing the same or similar services. A load balancing application is managed at the front end o f the server cluster to distribute user requests in the server cluster according to pre-configured load balancing rules, provide services, and maintain the servers. Load balancing bring good advantage such as bring faster application, low cost, the available resources will not be wasted, and no high-end devices are needed for the new resources. It is expandability. When services are increasing, the system can satisfy the needs by adding servers, without affecting the existing services and reducing service quality. Load balancing also has high reliability. When a server fails, the LB application or LB device redistributes user requests to other servers in the same cluster, ensuring uninterrupted services.
