Abstract

The increasing number o f passengers Trans Jogja bus stops can result in the existing capacity can not accommodate the number of passengers comfortably. Problems that often arise include delays resulting bus passenger waiting time is longer and there is a buildup of the number of passengers at stops. As a result of these problems, the capacity o f passenger stops can be full so that prospective passengers waiting outside the bus stop. Forecasting is one very important element in the decision. In this study using stationary and trend forecasting the data because the data are not significant changes between time and swell in certain periods and a normal in periods others. Time series methods for forecasting the number o f passengers on the Trans Jogja stop using exponential smoothing calculation and least square. From these calculations the value sought MAD (Mean Absolute Deviation) or least square error is exponential smoothing and forecasting results with small error. Forecasting will be better if it contains fewer possible errors.

Abstract

Practicum registration systems that exist on campus STTA previously done manually, where students will sign up to the admin to bring proof of payment practicum. Students are free to choose his own class, this often resulted in unbalanced number of students in the classroom lab that is consideredless  effective way. This makes the emergence of the idea to establish an MM algorithm is applied to a practical application o f automation systems. MM algorithm works by determining many lab classes based on students who took the KRS. Furthermore, students who have paid practicum will be immediately incorporated into the classes that are available with regard to the number of students and GPA o f students per class, so it will obtain practical classes by the number o f students and the average GPA o f each class balanced.Concept application using client-server database, where the database is on the Local Area Network (LAN) STTA. To facilitate the management admin, then the application will be tested on the LAN network and VPN (Virtual Private Network) network. LAN is a computers network that are connected to a computer server by using specific topologies, typically used in areas of the building or area a distance o f not more than 1 km (local area). While VPN is a secure way to access the Local Area Network that is in range, using the Internet or other public network to perform packet data transmission in private. By using a VPN, users can access the computer that is on the LAN even though the user is not in the same location with a LAN.

Abstract

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.

Abstract

Wi-Fi waves are commonly used as an intermediary in the communication relationships in the wireless network. However, the use o f Wi-Fi waves can be used in addition to getting the relationship in the network, the user is also able to detect and identify other devices by using Wi-Fi waves. Ad-hoc network is a network that can be built independently by the computer with the Microsoft Windows operating system, to enable ad-hoc device has to have an identity that is SSID, the SSID is then activate the device can be detected by other devices. Activation is done ad-hoc by the netsh command is a shell command in the Windows 7 operating system. An ID must be unique for each device as there is no dual identity, to maximize the identification process. Utilizing MAC address as an identity is used, allowing the device to be uniquely identified. In addition to the MAC address is added to the device profile in the identity o f the device for easier identification. Sapa application users can identify the device is detected, and recognize it as a co-owned devices. Scheme which is the concept o f the algorithm Sapa. Sapa application allows device activation or notebook PC with the Windows 7 operating system to be detected and detected by other devices with the Windows 7 operating system and applications are also active Sapa. Communication is established indirect communication that occurs in a single direction. Detection range can be done up to 77 meters distance.
