Abstract

Internet speed at all times is very helpful in carrying out and completing tasks, especially for workers and students. A slow internet connection can be a very annoying thing if it happens continuously. For this reason, this study discusses how to take advantage of internet links by dividing the traffic load equally or called load balance by using the Equal Cost Multi Path (ECMP) method in order to produce a maximum flow of packages so as to avoid overload on one connection down. From the test results, it is found that applying the load balance system to the ECMP method, the traffic load on the two internet lines can be divided evenly, the connection tag on the Mangle automatically determines incoming and outgoing packet connections so as to maintain and increase the bandwidth speed of the internet connection.

Abstract

Security is one of the important aspects of the process of exchanging information (messages). To prevent misuse or attacks by unauthorized parties (attackers) on private messages, the message must be secured. Several methods can be used to secure messages, one of which is by combining the Triple Data Encryption Standard (DES) cryptography method, Blum-Blum Shub (BBS) random number generator, and Least Significant Bit (LSB) steganography. In this study, the Triple DES cryptographic method is used to encrypt messages (embedded-message) with the extension .txt and the BBS random number generator method is used to determine the position of a random pixel to be inserted in the cover-image message. The LSB steganography method is used to perform the embedding process of the encrypted embedded-message at the pixel position resulting from the BBS random number generation process. The test results show that the system can extract embedded messages hidden in a stego-image with 100% accuracy. The maximum number of embedded-message characters that can be used in the test is 150 characters. The test also produces a stego-image that has an average Peak Signal to Noise Ratio (PSNR) value of 88.61, which means that the resulting stego-image has high quality (no significant quality degradation) and the presence of messages in the stego-image is getting harder to detect (imperceptibility).

Abstract

Traveling salesman problem (TSP) is one of the optimization problems to find the shortest route, where each city is only allowed to visit exactly once. The search for the shortest route can be completed by several algorithms, one of which is the genetic algorithm. Genetic algorithm is an optimization algorithm that works by imitating the evolutionary process in nature. During the evolution process, individuals with the best fitness may undergo changes that result in a decrease in fitness. Therefore, in order to keep individuals with the best fitness from becoming extinct during the evolutionary process, it is necessary to make copies of these individuals which is called elitism. There are three models of elitism, namely, Model 1: the best individuals are copied as many as m replacing the worst m individuals, Model 2: the best m individuals replace the worst m individuals, and Model 3: the best m individuals replace the worst m individuals selected randomly from 100%-m worst individual. The values ​​of the m parameters are 10%, 20%, 30%, and 40%. The tests were carried out with elitism and without elitism on different populations and cities. The test results show that Model 2 with m = 10% and population = 20 is the ideal parameter in solving TSP.

Abstract

Traditional games are a form of knowledge passed down from generation to generation. An example of a traditional game is Balap Karung. Currently, many game developers have created the "Balap Karung" application, but it has deficiencies in its User Interface. The User Interface is one of the visual elements that build a game. The User Interface is a communication mechanism between the user and the system that can receive information and provide information to the user to help direct the navigation flow until the user finds the solution. Creating a user interface in the 3D" Balap Karung" game as a visual design for the "Balap Karung" game will be built on an Android-based system. Creating a graphic user interface is done by researching the use of color in the user interface. The colors that match the "Balap Karung" game style will be used. The System Usability Scale (SUS) method was used as a usability test for the "Balap Karung" game. Through the results of game testing using the SUS method by distributing online questionnaires to be filled out by the respondents after they played the "Balap Karung" game, was obtained the average SUS score of 69.42 after calculating the results of the questionnaires from the respondents. According to the scores, it can conclude that the usability of the "Balap Karung" game is said to be good, with buttons and visuals following the purpose of their respective functions. According to the theory of calculating the SUS score, a score of 69.42, the "Balap Karung" game gets a Good rating in terms of usability.

Abstract

Tourism is a means to introduce a region's natural beauty and cultural uniqueness. Maluku Province, especially in Eastern Indonesia, has a sub-district called Banda Neira. Tourism potential includes historical tourism, nature tourism, and cultural tourism. However, disseminating information about tourist attractions in Banda Neira is still lacking because some information on the internet is not updated, there are no plans or directions to get to a tourist location and some historical information boards of tourist locations are also damaged or even non-existent. An android-based application was made as an answer using android studio tools, and the model used is the prototype. The final result of this application is that it can provide information about various tourist attractions equipped with pictures and maps to make it easier for visitors to choose places to visit while travelling.

Abstract

Plants, like other living things, need a combination of nutrients to live, grow and reproduce. Nutrients in plants can also be divided into two, namely mobile nutrients and immobile nutrients (non-moving nutrients). The condition of plants that are deficient or lacking in nutrients will experience growth disturbances and affect the yield of leaves or fruit. Leaf color can be a characteristic of plants under normal conditions or experiencing nutrient deficiencies. Deficiency of nutrients in plants will affect leaf shape, fruit production and plant age which results in stunted growth and rapid death of plants, in fruit production there will be loss of flowers or ovaries so that production will decrease. So far, plant maintenance has been done manually. Each plant is seen for later analysis of the results and it takes time to identify nutrient deficiencies. The aim of the study was to identify nutrient deficiencies in image-based chili plants based on the characteristics of the Red, Green, Blue (RGB) color and texture analysis using the Support Vector Model (SVM). The benefit of the research is to make machine learning-based applications to identify nutrient deficiencies which are divided into four classes, namely nitrogen (N) and phosphorus (P) deficiencies, P and potassium (K) deficiencies, N and K deficiencies, and chili leaves with normal class. .There are 120 plant data with an accuracy of 84.4%.
