This Online Thesis application aims to save a collection of theses at the Islamic University of North Sumatra in the form of electronic files and distributed so that they can be accessed and read online by visitors but cannot be copied files. This system has a facility to record user activities to find out visitor statistics, theses that are read frequently, browser statistics used by users and pages accessed by users, and has a fast search facility and detailed search for users. The article discusses how to design and implement Knuth Morris-Pratt String Matching Algorithm in the Online Thesis Application that is able to handle the storage of thesis files on the server in the form of Portable Document format (PDF) which is converted into Flipbook form using Turn Js as a tool in making flipbook display. This system was developed using PHP, MySql, and HTML5. The results obtained are a Web-based Online Thesis Application that features a flipbook that can help library management in managing digital theses, knowing which pages visitors are visiting, theses that are often read, and knowing visitor statistics. And can provide information about existing digital thesis and help library visitors in finding and reading digital thesis online. Keywords: thesis, flipbook, String Matching Knuth Morris-Pratt

At present, the development of cloud computing technology is experiencing rapid development. Also in line with the increase in the need and use of cloud computing technology itself. This rapid and high increase can cause an increase in load for the existing server so that it can result in overload on the connection path traffic. To avoid and optimize management on the server, it is necessary to share network load using various solutions available in the load balancing method. One solution is to use HAProxy software. HAProxy bridges at least 2 servers to apply load balancing and use the Round Robin scheduling algorithm. In the database management of two servers, replication Master to Master can be used by using MySQL as an existing database management media. From the results of tests conducted in this study, the HAProxy server is considered capable of handling problems compared to a single server. A replication that was tested was also considered to be a solution to bridge changes in existing data on the HAProxy server.

The use of data in the form of image files has become more widespread in various fields. Therefore, security of image files from unauthorized persons is important. Various techniques to reduce file size, including securing files, have been developed, one of which is compression. Compression technique becomes important in processing large images such as Bitmap images. Ziv Welch seal is a loseless compression algorithm that can compress images without any loss of pixel elements in them or the resulting compression image is identical to the original image. The image will be encrypted first and then performed the compression technique using the Ziv Welch Lempel algorithm. The resulting compression is no longer in the form of images but in the form of files with the * .mat extension. The different file formats from images to non-image files can help avoid cryptanalysis

The river often overflows during the rainy season and floods very detrimental. For the community. Therefore designed a monitoring tool and water discharge and rainfall intensity. This tool is constructed using a combination of water level sensors, ultrasonic sensors (SRF-05) and water flow to produce a monitoring system that provides participation early banji, make a program that can display the results surface monitoring and air discharge. See flood early and learn about the performance of surface monitoring systems and flood air discharge with faster rainfall and understand the microcontroller in measuring and controlling system. Tests carried out with aquarium prototypes and carried out. Measurement for one day on a continuous basis. Test results show that this tool can be updated reminded of flood early efficiently. With Thus, the tool designed is able to monitor the height of water activity, discharge and rainfall in rivers, programs are made capable run the designed tool and the results of monitoring can be accessed through LCD that is able to visualize water activities and this early permit system able to work to measure the height and air discharger rain and be able to implement data input from sensors too displays data on the state of the river so that it can be monitored through a computer. As well as a microcontroller capable of measuring and controlling the system accurately and input data from sensors in height and air discharge measurements as well. Rainfall intensity can be monitored via computer. Keywords: Rainfall, Water Discharge, Water level, Monitoring

Indonesia is a tropical country which consists of summer and rainy season. During the summer the room temperature will be high, so that will cause people who are in the room will feel uncomfortable or hot. To create comfortable conditions, air conditioning is needed. SPK is part of a computer-based information system. There are several stages in the decision support system, namely defining the problem, collecting relevant and appropriate data, processing data into information, and determining alternative solutions. The number of AC products on the market makes people feel difficult in choosing the right AC so that a decision support system is made. The VIKOR method focuses on ranking and choosing from a set of samples with conflicting criteria, which can help decision-makers to get a decision.

Bencana alam adalah peristiwa yang mengancam dan menggangu kehidupan manusia yang disebabkan oleh factor alam sehingga mengakibatkan timbulnya korban jiwa, kerusakan lingkungan, kerugian harta benda, dan dampak spikologis. Penyebab bencana alam gempa bumi adalah pelepasan energi yang dihasilkan oleh tekanan yang disebabkan oleh lempengan yang bergerak. Semakin lama tekanan itu kian membesar dan akhirnya mencapai pada keadaan dimana tekanan tersebut tidak dapat ditahan lagi oleh pinggiran lempeng. Upaya penanganan bencana alam perlu edukasi kepada masyarakat dapat mengalami perubahan tindakan dan upaya yg dilakukan agar masyarakat tidak menjadi korban dalam bencana alam, metode edukasi ini dapat mendorong masyarakat agar kesiapsiagaan demi menghadapi bencana alam gempa bumi, tsunami, longsor, dan gunung meletus. Upaya ini agar masyarakat paham dan mengerti factor-faktor yang memicu terjadinya bencana alam. Fungsi dari animasi stop motion agar masyrakat sekitar lebih paham dalam menghadapi bencana alam, agar masyarakat juga melakukan kesiapsiagaan terhadap bencana alam, dan masyarakat bisa melakukan titik yang aman jika terjadi bencana alam. Dengan adanya animasi stop motion ini dapat mengurangi dampak dari koban bencana alam, dan dapat mengetahu hal-hal apa saja yang dilakukan jika terjadinya bencana alam. Dari hasil data kuisioner dari 10 orang responden yang melihat animasi hampir 80 % pengguna dapat memahami dari hasil animasi tersebut, dan dapat diberikan kepada dunia pendidikan serta dapat juga menjadi media pembelajaran bagi masyarakat yang tidak mengetahui hal-hal yang dilakukan ketika datangnya bencana alam. Sesuai dari kuisioner tersebut dapat mendapatkan kepuasan dalam animasi tersebut. Dari hasil proses pembuatan animasi dapat disimpulkan dalam aspek-aspek yg dilihat dari hasil data kusioner sangat cocok kepada masyarakat dan mendapatkan kepuasan dari penilaian tersebut.
