Abstract

English has been an international language for communication among global citizens. A good English ability is highly required for Indonesians to be able to communicate with other people around the world. However, learners in Indonesia frequently encounter a myriad of challenges in learning English, including their reluctance to study new English vocabulary, worry of making mistakes, and feeling bored with the conventional teaching methods. The main four English skills that should be mastered by the learners are writing, reading, listening, and speaking. Excellent vocabulary mastery has been one of the key factors to become proficient at those four skills. English learning system using gamification approach serves as one of the solutions to improve learners' motivation in learning English. The use of gamification concept integrates several elements embedded in game applications, such as point collection, achievement, ranking, which are wrapped as English learning materials. Website-based learning system can be accessed without any place and time constraint, so that learners can study English autonomously and flexibly. This type of English learning system is developed using a software development model ‘Waterfall' with some certain procedures, including needs analysis, designing, implementation, and system test. This learning system has been examined by testing unit using White box method and validation test using Black box. Based on a series of the conducted tests, it demonstrated that the functional system has been running as designed and the result of the tests showed a 100% validity level.

Abstract

Information-centric networking is a concept of network architecture which is a content-centric model, so there is no need to connect directly to the server to get the content sought by the client. The in-network caching strategy in ICN is a caching strategy that stores content as cache spread across the network. In-network caching consists of two combinations of cache placement and cache replacement strategies. The cache placement strategy manages the placement of content on a collection of routers that acts as a content store, while the cache replacement strategy manages content replacement when the cache storage capacity is full. If the content is not removed quickly and precisely it will have an impact on the efficiency of the content that will be received by the client, resulting in a small cache hit ratio and increased latency. The cache placement and cache replacement strategies are interrelated with each other in in-network caching. Content needs to be disseminated to the network through the content store optimally and ensure that the stored content is the latest and has the chance of a cache hit. Performance evaluation of in-network caching strategies is based on cache hit ratio performance metrics, latency and path stretch. In-network caching strategy testing is done with the Icarus simulator which is specifically designed according to the ICN architecture. The results obtained from this study are the combination of ProbCache cache placement strategy with LFU cache replacement has a superior performance according to test parameters compared to other in-network caching strategies. ProbCache and LFU obtained an average CHR value of 54.02%, an average latency of 0.54 ms, and an average path stretch ratio of 4.76.

Abstract

The growing use of communication media makes information easy to obtain including information on products provided in online stores. The rating feature on the website is a way to see the quality of the product to be purchased so as not to make a wrong choice when purchasing a product that can have a bad impact. Abundant data about product reviews in various online sources are useful as study material for producers in improving product quality. The existence of review data that is found without accompanying the rating makes it difficult for producers to determine the review into a particular sentiment. In this study can accelerate the determination of reviews into sentiment in the form of rating. This study uses a linear regression method and k-nearest neighbor as a prediction method and the method of weighting the contextual valence shifter based on the lexicon dictionary after pre-processing. The use of n-gram includes unigram, bigram, and trigram aimed at increasing the accuracy of the system. The greatest percentage is obtained at tolerance 1 with the results obtained by trigrams greater than bigram or unigram with linear regression method, namely 77% accuracy while k-NN gets 75% accuracy at k = 20 and k = 30. The test results show the use of n-grams, especially bigram and trigram has a positive impact on the results of system accuracy.

Abstract

Indonesia is a tropical country that has the most biodiversity in the world. Almost all of the plants part like leaf, root, stem, fruit, flowers, seeds, and rhizome can be used for human health. In Indonesia the utilization of plants as medicine is so limited. Therefore, further research and continuous plant drugs or herbal remedies is really needed as well as the technologies are able to maximize the utilization. In 1980, David Weininger found a chemical notation for processing informations that related to a modern chemistry named Simplified Molecular Input Line System (SMILES) and that notation is specifically for computer used. On this research, K-Means Naive Bayes methods are used for the classification of the functions of the active compounds because this methods are able to grouping data according to their similarity and the classification process is much easier to understand. Based on the test results, the K-Means Naive Bayes are abled to give an accuracy system 85.45% with a 80% training data ratio and 20% testing data. The system also being tested using K-Fold Cross Validation with K-Fold as many as 10, the highest accuracy that can be given is 86.66% on 9th fold and the lowest is 70.37% on 1st fold. While the average of accuracy using the K-Fold Cross Validation is 82.6%.
