Abstract

Fault tolerance is the ability of the system to be able to continue running even when it is damaged. Fault tolerance has several types that are often used, in this study will be discussed about TMR (Triple Modular Redundancy). TMR is a hardware redundancy technique that duplicates 3 computing modules, and there will also be a voter polling the computational module. The voter's job is to see if any of the computing modules are damaged. However, in this study, the TMR voter will also be triplicated to reduce the possibility of a single point of failure, namely the event that the system cannot function if one of the modules is damaged, in this case is the voter. The device used as a computing module in this study is Arduino Uno, this study also uses the FC-37 rain sensor as an experimental sensor to retrieve the data. The result of this research is that the reliability value of the Triple Modular Redundancy system with Triplicated Voting is 98.49%, which is an increase compared to Triple Modular Redundancy with only 1 voter, which is 92.74%. The success rate of experiments conducted on Triple Modular Redundancy with Triplicated Voting also generally increased.

Abstract

PT Agung Aquatic Marine or PT AAM is engaged in the field of export and import of ornamental saltwater fauna and flora, so the data from transactions and the availability of products became important in running their business operations. But those data are managed on separate divisions inside PT AAM, this could slow down the process of decision making by the executives of PT AAM. Because of that, PT AAM plans to integrate these data into a centralized source that helps in decision-making. One of the solutions to that problem is the development of a data warehouse so that the data can be integrated and makes it easier to make a decision. In the development of the data warehouse, a flow or method is used to make it easier to design and implement the data warehouse that is the Kimball or Nine-Step Kimball methodology. The data warehouse that has been developed, produces 4 dimension tables with 2 fact tables, that is fact table of ordering and purchasing. Then a requirement validation test is carried out which results in a valid status on all of the test cases. Other than that, an ETL process performance test is carried out that shows the average time of execution is ± 24 seconds for each ETL process of fact and dimension tables. Next, an ETL process scheduling test is carried out that produces the task that runs automatically and without any problems.

Abstract

Learning activities require supervision and attention from the teacher as a facilitator. In general, one of the learning media, e-learning, only able to carry out learning activities without more supervision from the teacher. This can encourage students to do things that should not be done in learning activities, such as plagiarizing or cheating when the exam is carried out. Junior High School of Situbondo 3 as a school that does not have e-learning until this research is carried out, has problems in supervising students during exams. It is not uncommon for students who have below-average achievements to get high score on exams. Based on this problem, the researchers developed an e-learning that is able to detect potential of cheating when online exam is carried out. The method used to detect this potential is the Semantic Textual Similarity (STS) method for essay type exams and Angoff's B-Index method for multiple choice exams. The implemented module produces a value of up to 0,92 on the STS method and the right detection on the Angoff B-Index method. The module also reduces the actions of potential cheating with the potential for occurrence of 11,54% and 19,52% of the two classes with the same conditions.

Abstract

Sistem Informasi Akademik Mahasiswa Universitas Brawijaya (SIAM UB) is one of the information system services that is useful for managing student academic data. During the system development life cycle, it is necessary to evaluate the system. However, until now, there has been no research that evaluates or improves the design of the SIAM UB website when accessed via a desktop computer. In this study, an evaluation was carried out using the User Experience Questionnaire (UEQ) to determine the level of user experience and usability testing to understand the problem more deeply. The initial evaluation resulted in the conclusion that SIAM UB can meet the needs of users in obtaining academic information. However, there are still some problems. The evaluation results are used as the basis for improving the user interface design of SIAM UB. User Centered Design (UCD) is used as an approach in making design improvements and evaluations. UCD has four stages, namely understanding and determining the context of use, determining user requirements, creating design solutions, and evaluating designs. This UCD cycle runs for three iterations to produce a design solution in the form of a high-fidelity prototype. Then the high-fidelity prototype was evaluated using usability testing and UEQ. In general, the evaluation results of usability and UEQ testing on high-fidelity prototypes show a positive value and are better than the results of the current evaluation of SIAM UB.

Abstract

Some characteristics of clean drinking water are fresh water, colorless and not smoky. One of the water sources that are considered clean and worth drinking is through PDAM (Perusahaan Daerah Air Minum). Water from PDAM was chosen because it has gone through various physical and chemical processes, so that PDAM-assisted water is considered clean enough to be used for daily needs in the future. Factors that affect the level of water feasibility are usually determined from the mixed content of the water. One of the ingredients used by PDAM is chlorine as a disinfectant to maintain water cleanliness and protect from bacteria. Referring to the Regulation of the Minister of Health of the Republic of Indonesia 492 / MENKS / PER / IV / 2017, the upper limit of chlorine content in drinking water is 5 mg / L. Water quality classification system designed by utilizing pH sensors to know the acidity level in water, turbidity sensors to know the level of turbidity in water, and TDS sensors to know the amount of dissolved substance content in water. Then the system will store and process input data from the sensor using the fuzzy method of takagi-sugeno model to classify water quality based on its content into three groups, namely safe, processed and dangerous. During the testing phase of the system, from 4 experiments with 3 PDAM water samples, the accuracy rate obtained from the system and compared to existing tools was 100%.
