<![CDATA[The role of electricity is very important for every level of society and even electricity is very much needed as a means of production and for everyday life, so the importance of the role of electricity certainly has an impact on increasing electricity demand but this is not linear with electricity that has not been able to meet demand the electricity is so big. To overcome this, there needs to be interference from the government and the community in using electricity wisely so that the electricity needs do not become greater than the electricity supply. Therefore every household must understand effective electricity use. The observation method taken by the author is to collect and collect data from PT. PLN Lubuk Pakam Area. In addition, the author collects data from books related to the discussion that the author wants to describe and conduct research at PT. The Lubuk Pakam Area PLN is concerned with the discussion. The author also reads several journals concerned with the discussion material. The application of the Predictive Modeling method is expected to be able to predict the amount of electricity usage per household so that it is easier to regulate electricity usage. household electricity use tested by the Predictive Modeling method, the percentage results obtained for the accuracy of predictions, where the data on household electricity usage tested contained data on household electricity usage that were successfully classified correctly.]]>

<![CDATA[Currently, the use of digital cameras to capture images or photos is more than using a manual camera with film media. This is because digital image retrieval has many advantages, especially in terms of storage which no longer uses physical media (film) but uses digital media and a very long storage age of images without reducing the quality of the image. One damage that might occur is the blurred image (blurred image). This damage can be caused by several things including the age of the photo that has been long, and wet with water. The thing that can be done to avoid the occurrence of blurred images caused by old photographs is to treat the image state. But in reality, it is very difficult to treat the condition of this image. Several methods have been developed to improve blurred images, including using the deconvolution process for kernel blur, unsharp mask. In this study, an application was developed to make improvements to the blurred image caused by the age of the old photo using the unsharp mask method. Unsharp mask is one of the digital image processing methods that can be used to reduce the level of image blur caused by photo age and image maintenance errors. Unsharp word naming is because this method uses a more blurry image of the original image as a mask-making factor. After the mask is obtained, the mask will be added to the original image so that the image is sharper than the original image.]]>

<![CDATA[Pacman is an arcade game developed by Namco and released in Japan on May 22, 1980. Pac-Man, which is still popular today, has also been released on other platforms such as Game Boy and SNES. The designer of this game is Toru Iwatani, who is a Namco employee. The concept of the game in the Pacman game is very simple: Players must control the Pacman character to eat all the small dots and other special objects that are in the maze without being caught by 4 ghosts. The greedy algorithm is used to find the current shortest path from the position of the ghost character to the position of the Pacman character.]]>

<![CDATA[The use of CCTV today is very important as a support for emergencies around the area of the company / building, and serves to assist officers in the building security room. In this case the function of CCTV only helps the officer to minimize the frequent crimes, not to reduce from the crime itself. CCTV itself only displays the image and save it in HDD to see the incident occurring in the hook. The more powerful the quality of CCTV itself is still many shortcomings that developed the resulting image quality, the area captured by the camera, therefore the supervisory function is still less effective and efficient for all things crime. In this research. By using remote monitoring using Pro Surveillance System application. To facilitate monitoring.]]>

<![CDATA[Computer security is a branch of technology known as information security applied to computers. The goal of computer security is to protect information against information theft. The application of computer security is an effort made to secure performance and computerized processes so that they are not used, modified, interrupted and disturbed by unauthorized parties. While data compression is one of the important aspects of the development of information technology. Compression is converting data into forms that require fewer bits, usually done so that data can be stored or sent more efficiently. The speed in the process of sending information is something that is highly expected by using existing technology and will be hampered if the file containing the information has a large size. Not only kecepan, security factors are very important things in the exchange of information. This is because many irresponsible parties want to steal information and can be misused by that party. The compression technique using the Prediction by Partial Matching algorithm can overcome large file sizes because by using the algorithm the file size can be minimized. Whereas to improve the security of confidential information, then encoding text files using the ElGamal algorithm which has a level of security that is quite strong because of the difficulty in calculating discrete logarithms to solve them. The final result is a text file that has been encoded and has a smaller size.]]>

<![CDATA[Conventional cryptographic algorithms cannot be applied to solve a plaintext (message) into several ciphertext pieces because conventional cryptographic algorithms can only produce a ciphertext from a plaintext (message) In this case, cryptography can be applied, namely Asmuth-Bloom's secret sharing. The methodology used to analyze and design the Asmuth-Bloom secret sharing cryptographic application software is the Waterfall methodology. This research is intended to produce a learning software that is able to display work processes from Asmuth-Bloom's secret sharing and applications from Asmuth-Bloom's secret sharing. The working procedure described by the software includes the process of forming keys, the process of forming shadows and the process of combining shadow.]]>

<![CDATA[Student majors in secondary schools are not only determined by academic ability but must also be supported by interest factors, since the characteristics of a science demand the same characteristics of those who study them. In accordance with the applicable curriculum throughout Indonesia, the majors available in SMA include Natural Sciences (IPA), Social Sciences (IPS), and Linguistics. The majors will be tailored to the student's interests and abilities. The criteria for determining this department are based on the value of academic achievement, competency test scores and specialization. The number of students and various matapelajaran also affect the speed in determining student majors. In terms of selection of majors needs to be done with a mathematical method in order to run quickly and fairly, for example with the method of ELECTRE. The ELECTRE (Elimination Et Choix Traduisant la realitE) method is one of the most effective methods for MADM with qualitative and quantitative features. Looking from the above case then the author tries to solve the problem of selection with the model of Multi Attribute Decision Making (MADM). This research will apply an Electre method to address the determination of the majors quickly. This research uses Borg & Gall's method of research and development (1987). The results of this study is the results of expert system validation shows the value of 2.8 is between 2.51-3.25 which belongs to the category Valid and validation of the user shows the value of 3.22 is between 2.51 - 3.25 which belong to the category Effective .]]>
