Abstract

Stunting is a serious problem in children's health in Indonesia, so more in-depth knowledge is needed. Based on the results of the 2019 Ministry of Communication and Information survey, it shows that the Indonesian people have a poor understanding of stunting. A system is needed that can make it easy for the public to get stunting information accurately and quickly, so this research proposes the development of a dialogue-based chatbot that is integrated with the Telegram platform, which can be used as a step to increase public accessibility regarding stunting information. Chatbots are able to effectively assist humans in providing automatic answers to questions from various topics. This research aims to provide stunting information to the public and provide access to stunting information easily and quickly. The stunting information chatbot was developed using the Dialogflow platform by applying natural language processing (NLP) which is integrated with the Telegram application. The chatbot testing results using the black box test obtained an accuracy of 90%, which shows that the output provided by the chatbot is appropriate. The test results using the user experience questionnaire (UEQ) showed that the attractiveness score was 1.80, clarity was 1.17, efficiency was 1.81, decision was 1.74, stimulation was 1.59 and novelty was 1.14.

Abstract

Social media is a medium that is often used by someone to express themselves. These various problems on social media have encouraged research in sentiment analysis to become one of the most popular research fields. Various methods are used in sentiment analysis research, ranging from classic machine learning (ML) to deep learning. Researchers nowadays often use deep learning methods in sentiment analysis research because they have advantages in processing large amounts of data and providing high accuracy. However, deep learning also has limitations on the longer computational side due to the complexity of its network architecture. K-nearest neighbor (KNN) is a robust ML method but does not yet provide high-accuracy results in multi-lingual sentiment analysis research, so a hyperparameter tuning KNN approach is proposed. The results showed that using the proposed method, the accuracy level improved to 98.37%, and the classification error (CE) improved to 1.63%. The model performed better than other ML and even deep learning methods. The results of this study indicate that KNN using hyperparameter tuning is a method that contributes to the sentiment analysis classification model using the Twitter dataset.

Abstract

Computer vision usag on an attendance system role is to make sure that the attendance cannot be done by another person. Besides that, the attendance system could also use  geolocation to determine the attendee location and the supposed attendance location. These process takes a considerable amount of server resource. To reduce the load of a server, a client side process could be used. Face recognition is done by using face-api.js which is a javascript module build on top of tensoflow.js core that implements some CNN (Convolutional Neural Networks) to detect, recognize, and extract feature of a face, that is optimized for website and mobile device. For the calculation of geolocation coordinate an equirectangular approximation formula is used. The accuracy of face recognition ranges between 93% to 97% and the geolocation calculation takes around 0.008300000003ms to complete.Key words: Face Detection; Geolocation; Tensorflow; Attendance   AbstrakPenggunaan computer vision pada sistem absensi berperan sebagai pengaman untuk memastikan bahwa absensi tidak dapat diwakilkan oleh orang lain. Selain itu pada sistem absensi juga dapat ditambahkan sistem geolokasi untuk menentukan jarak pelaku dari jarak lokasi yang sudah ditentukan. Proses-proses tersebut memakan sumber daya besar pada server. Dengan mendelegasikan proses tersebut kepada klien, beban serer akan berkurang secara signifikan.

Abstract

Playing games is one of the activities in great demand by the elderly, young, and children, whose use is generally only to fill spare time, get rid of boredom, and for fun. Therefore in this final project, an educational game based on Role Playing Game will be developed, which is helpful for learning by applying ten-finger typing education because, until now, learning has only been done through books. Delphi 7 is used in its manufacture. The Delphi language is a programming language that can be configured in such a way that it can work with other devices to form a control system—and apply the Finite State Machine method to process the gameplay control flow, which consists of 3 levels where the player will complete the answers for each class to be able to proceed to the next level. The results of this game can be used as learning media for children, and they can learn while playing to add knowledge in the field of typing. With these benefits, it is hoped that later games can be developed and applied among students. A game uses electronics and is entertainment in the form of multimedia that is made as attractive as possible so that players can get something that there is new satisfaction. In the Big Indonesian Dictionary, an online game is used to play goods or something that is played. The growth of the game industry is developing, especially in various types of games which include Maze Games, Board Games, Card Games, Battle Card Games, Quiz Games, Puzzle Games, Shooting Games, First Person Shooting (FPS), Side Scrolling Games, Fighting Game, Racing Game, Simulation, Strategy Game, Role Playing Game (RPG), Adventure Game, Sports Game, and Edutainment Game.

Abstract

Coronary artery disease is one of the diseases that often attacks humans. The cause of this disease is due to narrowing or blockage of the coronary blood vessels that supply blood to the heart. The diagnosis of coronary artery disease by medical personnel has so far been constrained by the limited number of doctors, in terms of the number of doctors and time, because the number of specialist doctors is limited. The limited number of doctors causes several difficulties for medical personnel who diagnose the patient's disease and over time can become a serious problem. Information technology that can help medical personnel is by applying data mining techniques which are techniques to help diagnose coronary artery disease. Data mining can identify patterns or relationships between disease symptoms and diagnostic results, so that patients with a high risk of developing the disease can be identified. The Naïve Bayes algorithm is one of the algorithms of the Data Mining classification technique, which is based on Bayes' theorem. The C4.5 algorithm is one of the algorithms of the Data Mining classification technique, which uses decision trees in classifying data. Algorithm comparisons are carried out in order to obtain the appropriate or best algorithm for use in diagnosing a disease. The comparison process of the Naïve Bayes algorithm and the C.45 algorithm in diagnosing coronary artery disease, obtained the best algorithm results based on the largest percentage value, namely the C4.5 algorithm, with a value of 46.9%.

Abstract

One of the important and complicated stages in the construction project development process is selecting the location to be built. Project success and customer satisfaction will be influenced by good location selection. It is very important to use a Decision Support System (DSS) to help make more organized and informed decisions in situations like this. This is an SPK proposal for a housing development location that combines the COCOSO (Combined Compromise Solution) and TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) methods. The COCOSO method, which considers several conflicting criteria, was used to resolve doubts and site selection problems. Additionally, locations are ranked using TOPSIS based on how close they are to the ideal solution. Identify important factors that influence location selection including accessibility, land prices, infrastructure, and environmental factors. Next, assessment and ranking are carried out using COCOSO to provide the best compromise solution, and the results are evaluated using TOPSIS to determine the best location. A fictional case study is used to test system performance. Potential housing location data is used as an example. The simulation results show that the proposed SPK can provide complete and reliable location recommendations for housing developers. COCOSO and TOPSIS integrated in this SPK help decision makers choose locations by considering trade-offs between various criteria and choosing the location closest to the best solution. This SPK can help developers make strategic decisions about housing development locations.

Abstract

In the field of image watermarking, the singular value decomposition has good imperceptibility and robustness, but it has high complexity.  It divides a host image into matrices of U, S, and V. Singular matrix S has been widely used for embedding and extracting watermark, while orthogonal matrices of U and V are used in decomposition and reconstruction. The proposed signum of cosine matrix method is carried out to eliminate the generation of the three matrices at each block and replace it with a signum of cosine matrix. The proposed signum of cosine matrix is performed faster on the decomposition and reconstruction. The image is transformed into a coefficient matrix C using the signum matrix. The C matrix values are closer to the S value of singular value decomposition which can preserve high quality of the watermarked image. The experimental results show that our method is able to produce similar imperceptibility and robustness level of the watermarked image with less computational time.
