Lamp is a kind of electronic that created light. Light is obtained through the flow of electricity as a current to add a voltage. the die and the life of light are controled by humans using switch. Applying the Internet of Things, as known as IoT determined the life and the die of a lamp by determined by the active light censor. The die and the life of the lamp automatically depends on the light sensor by capturing the intensity of the light produced. The result of the function test found that the data in the form of lux value generated by the light sensor, the value is exposed on a website with the display of graphics and websites serve as a web service provides control values to determine the response lamp, if the value of lux above 30 percent then the lights off And vice versa if under 30 percent of the lamps are on, so that a small value will be sent to the lamp and the lamp will respond that the lights are off or on. So that humans only act as a watchdog and control of the value generated by the light sensor.

Defense system against interference when the activity is generally done manually by the administrator. This resulted in the integrity of the system depends on the availability and speed of the administrator in response to disturbance. In the current era of information technology, almost all information is important for an institution can be accessed by its users. Disclosure of such access raises new security issues in part of a computer network system that is very important to maintain the validity and integrity of data and ensure availability of services for its users.In this issue then designed a system to detect any interference. The detection is based filtering on the port service, using the programming language Delphi 7. The data obtained from the filtered traffic data packets passing the proxy server. By building a system that can work automatically and in real time, then perform the detection of intruders or illegal activities which will then be reported to the administrator.With this administrator can find out the use of illegal ports through port filter techniques on the traffic data service in and out in real time, from both internal and external networks. Administrators can do the monitoring without having to depend on availability. With such a system administrator can perform tasks more efficiently in maintaining the validity and integrity of data.

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.

Many colleges already apply web based academic information system use internet connection, so it is need a system security to protect from attacks such as SQL Injection and Brute Force. Honeypot is a system security which devide two system that are original and fake system. Original system used by user to access academic information system that source from correct database. While fake system used to separate hacker and user. Hackers who try to enter with SQL Injection is send to fake system directly which has wrong data. This fake system seems correct and all action that was happened in will be noted on log history. When hacker try some password ese Brute Force, system will reset user password automatically. This system already test with 79 times SQL Injection and 29 times Brute Force attack. All attacks can handle nicely with honeypot algorithm.
