Abstract

Perum Perhutani is a BUMN (Badan Usaha Milik Negara) whose business portfolio is managing and developing 768 ecotourism in Java and Madura. Perhutani has not been able to develop the tourism objects optimally due to the lack of data and information regarding tourist preferences about tourism objects despite the effort they have done. Sentiment analysis using Multinomial Naive Bayes was carried out to determine tourist preferences from three aspects of tourism objects managed by Perhutani. The three aspects are attractions, accessibilities, and amenities. Reviews obtained from TripAdvisor will be classified into three classes, namely positive, negative, and neutral. The purposes of this study are first, to find out the implementation results of Multinomial Naive Bayes in sentiment analysis process, second, to find out the values ​​of precision, recall, and f1, and lastly to know the results of usability testing from the dashboard. The results of the classification process for the attractions aspect is 69.89% of accuracy. As for accessibilities and amenities, the accuracy values ​​are 61.67% and 63.01% for each aspect. Information about of tourist sentiment is displayed on a dashboard which is then tested by Perhutani using SUS (System Usability Scale) and gets a score of 65. That result means the dashboard has “Good” rating and in range Marginal (High) for acceptability.

Abstract

The Massive Open Online Course (MOOC), which was supposed to revolutionize the world of education, did not happen as expected. MOOC registrants who survive to complete the course are very low, only around 2-11% of the total registrants. After being researched, the registrant's motivation plays a significant role in keeping the registrant following the given course to completion. Gamification is present as a solution to this problem. Gamification is a concept that applies game elements to something that is not a game to increase participants' motivation and engagement. In the context of this research, it applies to learning. Based on data from the Bureau of Labor Statistics in America, Web Developer jobs are projected to increase by 8% or about 14,000 new jobs, exceeding the average for other jobs in 2019-2029. The World Wide Web Consortium also said that HTML and CSS are the core technologies in creating the web. In response to this problem, an e-learning application was created for learning HTML and CSS by applying the concept of gamification, which was eventually named Hyper Sheets. The hope is that this application can maintain or even increase student motivation. The three main features of this app are interactive materials, exercises, and challenges. In developing this application, the Waterfall model is used, which finally gets 13 functional requirements and 1 non-functional requirement. The tests were carried out on functional requirements, namely unit testing with white box testing techniques and integration testing along with validation testing with black box testing techniques. These functional requirement tests get 100% valid results. In non-functional testing, namely usability testing, using the SUS method ultimately resulted in a score of 81.55. This score belongs to the "Acceptable" category, which is satisfactory to the application users.

Abstract

Education is one of the most important needs for human civilization, especially for children and teenagers. The current pandemic condition is forcing education to use online learning alternatives. Codemaniac is one of the e-learning which is builded using gamification techniques to increase student motivation. However, Codemaniac does not yet have adaptive features that can maximize the behavior of each user. To overcome this problem, further development of Codemaniac will add adaptive features by utilizing the recorded user behavior contained in the log file. Based on the recorded user behavior, clustering will be carried out using the fuzzy c-means algorithm so that three types of clusters will be formed, each cluster will present a different user interface. This system is compiled using SDLC waterfall with the addition of the Python programming language. In its development, it produces 3 actors, with an additional 5 functional requirements and 1 non-functional requirement. To test the system, the wthite box method is used for unit testing and the black box method is used for validation testing.

Abstract

Vannamei shrimp is a shrimp in the tiger prawn pond culture favored by the Indonesian people because it has an economical price and has the expected prospects and benefits. The cultivation of vaname shrimp is quite tricky compared to tiger prawns. Vannamei shrimp is vulnerable to diseases such as White Faces Syndrome (WFS) and White Spot Syndrome (WSS) which results in death and a decrease in the amount of production produced. The decrease in production results is also caused by poor air quality management such as poor air circulation, irregular ponds, and providing excessive feed which causes poor air quality. Therefore, an algorithm is needed that can predict the production of vannamei shrimp based on the quality of the water used so that cultivators can take preventive actions against problems that occur. In this study, prediction is carried out into several processes, namely, pre-processing, data normalization, prediction, and calculation of the error value. In the prediction process, the algorithm used is Multiple Linear Regression (MLR) a combination of Gradient Descent (GD) with Apache Spark and in the process of calculating the error value using the Root Means Square Error (RMSE) method. The results of this study are based on the testing process using water quality data for 1 harvest of ponds owned by FPIK UB partners in. Lamongan which consists of 18 parameters in 4 different pools, the RMSE value is 210,634 and the Adjusted R-Squared value is 0.8341 with a training and testing data percentage of 70%:30%, the number of features is 18, the alpha value is 0.33, the error value is 0. .01 and the number of nodes is 6.

Abstract

The implementation of health services in a hospital has a very complex organization and organization. Currently, many hospitals, clinics, health centers, and doctors' practices have used information systems to facilitate data management and improve the quality of service to patients. However Dr. Hospital Iskak Tulungagung still faces difficulties in patient registration and searching for medical records. One patient takes 5-15 minutes to complete the registration process, including monitoring patient medical records or creating medical record documents for patients who are first seeking treatment. Seeing these problems, the authors developed an online registration system and electronic medical records, so as to reduce patient queues at registration and maximum patient care. This system will apply the waterfall model for its development process. This model takes a systematic and sequential approach. The test was carried out using a test unit with the whitebox testing method on 3 functions, namely data input, physical examination, changing profiles, adding to the drug list. Of the three test units that have been carried out, it can be declared that they have passed the unit test. The validation results in a valid value in each test case against the 84 tested cases based on 46 functionality, therefore the system is declared to have passed the validation test. In the compatibility test using SortSite resulted in a web that is able to run well on 9 out of 11 browser versions. On the usefulness, the total answers to each of the 10 questions were tested to 20 respondents. The results of the reusability test of this system obtained an average score of 80.4 which is included in the above average classification.

Abstract

One of the main causes of vehicle traffic accidents are human factors such as sleepiness during driving, which is 35% of total traffic accidents in Indonesia. In order to prevent and minimize the percentage of traffic accidents and material loss caused by that factor, through this research will be developed a fatigue detection system for car drivers. This research will be focusing on the development of fatigue detection method through visual cues with Percentage of Eye Closure (PERCLOS) method, which in that method measures the eye closure percentage against time to indicate the fatigue of a car driver. The system will be able to give the car driver a signal for a detected fatigue, directing the car driver to an area to rest, contacting the close related person to the car driver when fatigue detected and an emergency function to do that without a need of fatigue detection. This system will be implemented in a smartphone with Android-based operating system. Waterfall model is used for the development process of this system. The requirement analysis produced produced 8 functional requirements and 1 non-functional requirement in the development process. Unit testing has 100% pass result and validation testing has 100% pass result which has 15 test cases. The system expected a web-based implementation that can be used to integrate the fatigue detection system to handle user data in fatigue detection system in a large scale.
