Abstract

There are many virtualization technologies currently available, one of which is LXD on the Linux operating system. LXD can be used to build a Private Cloud. Currently, the operating system practicum lectures at Caltex Riau Polytechnic are still using Virtualization Software such as VMWare or Virtualbox which often cause problems such as virus threats, data loss, and configuration errors. For this reason, it is necessary to design and implement a centralized system using cloud computing and virtualization so that these problems can be avoided. The Cloud Computing system was created using LXD with the configuration that each student will have a virtual server account on the Cloud System. From the tests carried out, it was found that LXD can be used for operating system lecture with a memory requirement of 7.6GB with 20% CPU usage.

Abstract

The development in the era of globalization and the rapid progress in the field of information technology has had a considerable influence both in the field of education. Several problems can be explained related to the achievement of results in predicting the results of new student admissions at SMK Mulia Pratama in the digital era. The promotion is quite complicated because there is no target for the results of new student admissions so the promotion does not know the achievement of new student admissions who are registered for each promotion. To solve this problem, the naive Bayes method is used. Naïve Bayes is an algorithm that can be used to predict the results of new student admissions that can be categorized as achieved or not achieved. The data was used in this study from January to December 2018. From the results of the application of the nave Bayes method, the highest probability value is in class P(X). Receipt of acceptance prediction = No so that it can be concluded that the results of acceptance are included in the classification of "No" meaning that every new acceptance improves.

Abstract

Technological developments make any information can be spread in a short time. Technology can also be used to advertise any place, business, product. Technological developments cannot be separated from every activity carried out by humans, one of which is the determination of the nearest tourist attraction. Tourism is a place for relaxing and can visit until the time desired by visitors. From the above explanation, it can be said that a destination is a place that can be visited by foreign and domestic tourists. Searching for the shortest route is an obstacle that is often faced by every seeker of alternative paths to reach their destination faster. Several other methods can solve the problem of finding a route. One method that can solve this problem is using the heuristic search method. One of them is the Greedy Best-first search algorithm. This algorithm works by taking into account the approximate cost. Selecting the next best node is done by examining the estimated cost obtained using a heuristic function. Given the problems above, it is necessary to make a solution to determine the shortest route to assist tourists in choosing the route to be traversed in tourism in Deliserdang.

Abstract

Mushrooms are one of the plants that have high nutritional content that other types of vegetables do not have. This plant is easy to cultivate because it easily adapts to the environment. The risk of loss in the oyster mushroom business cannot be avoided because it is not careful or diligent in maintaining oyster mushrooms. As a tool, an expert system is used to identify the type of oyster mushroom disease using several methods including the backward chaining method. The backward chaining method is a method that starts from the conclusion of several existing facts to refute or support the hypothesis. The results of the research and discussion that have been carried out have concluded that an expert system designed to be able to diagnose fungal plant diseases, the method used can be used as an alternative in calculating the diagnosis of fungal diseases and an expert system designed to make it easier for farmers to diagnose diseases that occur in fungal.

Abstract

Happy World is a playground for children or adults on JL. Serdang Baru, Deli Mas Plaza Complex 3rd Floor which has customers or consumers who visit to want to play. The problem with Happy World is that it doesn't have the technology yet, in terms of structuring or setting the cashier's service time, which still uses a manual by taking a queue number. These problems resulted in the accumulation of customers at the cashier and did not comply with health protocols. Therefore the company needs fast service to serve all its customers without compromising the quality of the service. That builds customer confidence in the cashier's service and creates a system to help make the queue more neat and orderly so that the services provided can also satisfy the customer, namely the Queue System. From the test results, the performance obtained in the payment queuing system needs at the cashier (server) where the average service time spent at the cashier and efficient service time, the company exceeds the service time limit that has been set, which is 10 minutes to reduce the level of service delivery. density, the company will repair the system.

Abstract

Cryptography is the science and art of keeping messages safe from being known by unauthorized persons. Most cryptography uses mathematical calculations both in calculating the secret key and in calculating the secret code that will be used. Thus, the information in the message will be kept safe and confidential. One of the classic cryptographic algorithms that can be used to ensure data security and security is the Hill Cipher method. Hill cipher is symmetric cryptography, also known as hill code, which is the application of modulo arithmetic to cryptography. This cryptographic technique uses a rectangular matrix as the key used for encryption and decryption. The system created can be used as data encoding in the form of characters in the form of letters by dividing block each encrypted character.
