Abstract

Diabetes mellitus is a common disease among the people. One of the active preventive things to deal with type 2 diabetes mellitus is to do regular exercise, and eat nutritious foods and have adequate nutrition for 1 day. In getting enough calories or energy according to the needs of patients, calculations can be done manually. But if the process is done manually, it will take a long time so that if this is implemented in a health institution, it will be very inefficient given the large number of patients in the queue. This problem can be solved by using an artificial intelligence system using a genetic algorithm that is performed hybridization with simulated annealing. Simulated Annealing can help the genetic algorithm come out of optimum local conditions, due to its nature that can accept solutions that are not better or better than the previous solution. Simulated Annealing was successfully added to help the genetic algorithm out of optimum local conditions, this was indicated by the highest fitness value of 0.998, with the percentage difference between the patient's actual needs of calories by 0.18%, carbohydrate by 0.20%, protein by 0.69% and the last is fat at 0.27%.

Abstract

Generally, timetabling is done by using conventional tables or spreadsheets. As a result, its affect the quality of timetable and it could drain time and energy if data is considered in thousands. Based on these problems, it requires an intelligent system that not only automates its process but also optimizes the result. Particle Swarm Optimization (PSO) is a popular metaheuristic algorithm to solve multiparameter optimization problems. Discrete PSO is used in this study because of combinatorics problems. Various strategies are also used in this method such as transposition method for particle movement, guided random strategies, and particle's position repair strategies. The strategies is expected to improve timetabling result. With the various strategies that have been used, this study will use “Hybrid Discrete PSO” approach. The test results showed the combination of parameters that resulting the best fitness are b_loc=1, b_glob=0,8, b_rand=0, number of particle is 200 and number of iteration is 40. The resulting fitness is 0,018896357 with the total execution time is 34 minutes 16 seconds 358 miliseconds.

Abstract

Faculty of Computer Science (FILKOM) Universitas Brawijaya is one of the faculties that have studied technology and computers in Indonesia, from the data of respondents I got through questionnaires distributed to 100 FILKOM students there were about 67% thought that programming was important, but 52% of respondents find it difficult to follow learning in the first year of lecture for various reasons, one of which is the lack of reference to relevant learning materials so that this study aims to develop an e-learning website interface for students of the Faculty of Computer Science Universitas Brawijaya using the Goal Directed Design (GDD) method. The GDD method has six stages that provide website development solutions in accordance with user objectives, namely Research, Modeling, Requirements, Frameworks, Refinements, and Support. From the whole process, data obtained that support user needs such as persona and user journey, hierarchical task analysis, wireframe design, high-fidelity prototype, and finally the results of the evaluation. The evaluation process is done by 2 methods, namely user testing and expert evaluation using immersion testing by asking several experts to try the product and provide input. From the user side we get positive and negative inputs such as the use of a simple and easy to understand design, some buttons and information that is less informative, to the use of live coding features that should be given a special page. While on the expert side, the input is in the form of adding debugging flow visualization, to adding interactions in the form of threads on the discussion forum page.

Abstract

Test case prioritization is a strategy of regression testing. It can reduce the cost of regression testing. Test case prioritization based on lexicographical ordering is considered to be the best technique based on its Average Percentage Fault Detection (APFD). This technique determines test case prioritization based on coverage information of each test case. There have been no studies that implement this technique into a system and research shows that prioritizing test cases based on code coverage is expensive both in terms of time and resources. Because the more number of test cases, the greater size of the code coverage information that have to be read. Therefore, this study developed an application system for test case prioritization based on lexicographical ordering. This system aims to help the process of reading coverage information and determining test case prioritization automatically. So this system is expected to accelerate the determination of test case prioritization. The results of testing phase show that the system has 100% accuracy with reading coverage information in each test case also finding prioritization in less than 8 seconds. This paper will summarize the application system development process. The stages described from the introduction, research methodology, results and discussion, and getting conclusions from the research.

Abstract

Functional requirement is a functions that must be had in the system that is being develop. Software requirement must be able to overcome the problems that is being faced by stakeholders so that it can facilitate the work of a stakeholder. Determination of priority requirement is something that can determine which system is useful or even fails in its development. An analyst's mistake in ranking the importance of a requirement often results in failure in the development process due to problems of time and resources. Genetic algorithm is an artificial intelligence method developed to solve complex problems in various sciences, such as mathematics, physics, biology, and so on. The usage of genetic algorithm methods in the process of calculating the priority of this requirement is done by calculating the value of disagreement on a chromosome which is carried out continuously until the optimal priority requirements are obtained. The result of these methods is obtained a system that be able to calculate the priority requirements that are feasible to use as a reference in ranking system requirements priority.

Abstract

In order to complete their thesis, students need a supervisor. Thesis supervisor plays an important role as a good facilitator, motivator, and director so that the thesis can be completed and ready to be tested. The inappropriate determination of supervisors can hamper the student's thesis guidance and work process. For this reason, an effective system to reccomend thesis supervisors for students is needed to minimize errors that may occur in the determination of the thesis supervisor. The recommendations given are not only based on personal knowledge, but also consider lecturers' researches, KJFD, majors, quotas, positions, and lecturer workload. The lecturer research data used was obtained from Google Scholar, functional position data was obtained from forlap.risetdikti.go.id, and the department data, quota, and lecturer workload were obtained from the Information Systems Management, IT Infrastructure and Public Relations of Faculty of Computer Science (PSIK). The validation test results show that the system built was in accordance with the requirements defined. The usability test results that utilize the System Usability Scale (SUS) show the system usability level is 90% which means system is in the acceptable category..
