Abstract

In software development there are stages of testing that have a very important role. Testing ensures that in the system there are no bugs and errors. Continuous software changes make it impossible to carry out the overall test. However, changes that occur in the environment, platform, etc., must be re-tested as a whole. To overcome the overall testing will be time consuming, expensive, inefficient and ineffective. So that to overcome the overall test requires regression testing with model-based prioritization test case strategies. To deal with this problem, a manual calculation of the test scenario is carried out with a prioritization test case strategy with weighting factors in the UML activity diagram model. Manual calculations have disadvantages such as requiring a lot of time, human resources, and so on. Therefore an auxiliary a tool is made for the calculation of test scenario priority based on the UML activity diagram. This system was built with C # technology and tested using the white-box testing method on unit testing as well as the black-box testing method in validation testing. On unit testing and validation testing, the test results are 100% valid.

Abstract

The process of determining some kind of food become important because it will determine the food that will be processed in the system that recorded the food for health and diet purpose. The process of determining food consist of preprocessing process and then changing the color model of the image from RGB to HSI. The next process is color feature extraction with Color Moment method that will generate the mean feature, standard deviation feature, and skewness feature from every color channel. Then, for shape feature extraction will using Morphological Shape Descriptors that will generate the length feature, width feature, diameter feature, and aspect ratio feature from the image. After the feature get extracted from the image, do the classification process with Naive Bayes Method with the help of LogSumExp for the probability calculation. The result in the testing of the effect of testing data generate 78% accuracy value when using 100 testing data. The result in the testing the effect of image dimension generate 81% accuracy value when using 300x300 pixel image for testing. The result in the testing the effect of number feature used generate 83% accuracy value when using feature from Color Moment only. The conclusion is, the feature extraction Color Moment and Morphological Shape Descriptors with Naive Bayes classification can be used to determine the kind of some food.

Abstract

Sidoarjo Regency Government has an e-government service called P3M (Pusat Pelayanan Pengaduan Masyarakat) which is implemented to accommodate various public aspirations and complaints. Based on the Citizens Satisfaction Index (IKM) survey in the first semester of 2019, P3M application only worth as 64.7 (not good), besides that, the P3M itself stated that the media that was the favorite of the citizens to submit their complaints was not P3M application, but Facebook. This study aims to describe the acceptance of the citizens of Sidoarjo Regency to P3M applications based on the Unified Theory of Acceptances and Use of Technology (UTAUT) framework that employed performance expectancy, effort expectancy, social influence, trust of the internet, trust of the government, trust of the CSC, facilitating conditions, behavioral intention, and use behavior. Data collection is done by distributing an online questionnaire that contains a total of 25 questions to 100 samples selected based on purposive sampling criteria. The research data was processed using a descriptive statistical approach and results were found the acceptance of the citizens of Sidoarjo Regency toward P3M applications based on the UTAUT model was categorized as high (61.91%). However, there are four variables that have below-average values, i.e. trust of the internet, trust of the government, trust of the CSC, behavioral intention, and use behavior. As a recommendation, these variables need to be optimized for implementation improvement in the future.

Abstract

Wireless Sensor Network (WSN) is a wireless network composed of individual devices distributed throughout the monitored area. Water monitoring system has been done using ZigBee protocol monitored temperature, dissolved oxygen, and acidity. ZigBee has disadvantages in range aspect so it's not suitable for monitoring in wide area. One of the many protocol that has wide network range is LoRa. LoRa is Low Power Wide Area Wireless Network (LPWAN) for IoT applications. This Research focused on the mechanism of data flow from sensor node to data visualization component. Architecture in this research consist of sensor node, gateway, cloud server and data visualization component. Sensor used are temperature sensor, acidity sensor, turbidity sensor and dissolved oxygen sensor. Data that has been acquired from sensor node then converted into struct. Struct data then sent to gateway using LoRa. Gateway then do the conversion from struct to JSON. Data that has been converted to JSON then will be sent to cloud server to be stored in the database using HTTP protocol. Functionality testing is applied to ensure the system work as it should be. Performance testing is done with successful rate parameter with range and time interval as the variables. Based on that testing this research can be solution to the water monitoring problem especially at the long range monitoring area.

Abstract

Every year at Library of Brawijaya University procures books to increase the attractiveness of readers or to provide the best service for readers. However, to carry out a maximum book procurement, an adequate budget is needed for the needs of all books needed by each department in Brawijaya University. Therefore, in this study a system was created which was able to optimize the number of books obtained with the budget set in the library of Brawijaya University by applying the genetic algorithm method. Genetic algorithms generate chromosomes with permutation genetic algorithms, each gene represents 1 book title per department. After chromosome generation is carried out, a crossover reproduction process and mutation reproduction will be carried out to produce new individuals. Then an individual evaluation and selection is based on the highest fitness value. After testing, the results of the parameters of the best population were obtained = 160, parameters of many generations = 2000, crossover rate 0.5 and mutation rate 0.5 which gave the opyimal results of the library book procurenment by the number of book purchased 1077 books.

Abstract

The data sending mechanism between a resource-constrained sensor and an Internet-of-Things middleware (IoTM) must be considered to enable remote and periodical data recording. Such recording is paramount in the context of human heart monitoring. In a previous study, Bluetooth was used in a health-data sending mechanism from sensor to smartphone. However, the solution introduced new problem that is silo. Meanwhile, the Bluetooth Low Energy (BLE) protocol is more compatible to the resource-constrained sensor and has safe radiation levels. Also, the smartwatch is popular for recording human heart rate. Then, the silo can be averted by applying event-driven IoTM. Thus, this research proposes a health data-sending mechanism from smartwatch to IoTM utilizing BLE by implementing BLE gateway on the IoTM. The health data is the smartwatch user's heart rate measurement. The health data are uploaded to a cloud server via IoTM's internet gateway device (IGD) for analyzing. The research's result is a functional health data-sending mechanism that satisfies the sensor's resource-constrained characteristic. The health data has a maximum size of 17 byte. The optimal distance between the smartwatch and the IoTM is 10 meters, with a maximum end-to-end delay of 3.7 seconds and a minimum Packets Reception Ratio of 96%.

Abstract

Placement of majors is one of the actions that can support the ability and motivation of student learning. Placement of the department itself has several factors that are used as considerations to determine the majors according to the abilities and interests of students. Factors used in determining majors between student psychological test results, report card grades for junior high school, BK evaluation, student interest, and parents' interests. Efficient it is not efficient. In the process of validation, the results of department placement are needed for 1 semester by looking at student learning outcomes data. In the placement of majors a system is needed that can help in classifying students' majors quickly and accurately, can be adjusted to the completion time of majors and errors in the arrangement of majors that are not in accordance with the interests and abilities of students. In this study using the Extreme Learning Machine method in grouping majors in high school students. In applying the ELM method the classification results obtained with the best average value of 98% using 14 features. To transfer data, practice and test the data used is 80:20, and the weight value is changed [-1,1], the value is biased with a range of [0,1], and use the activate sigmoid function.

Abstract

Brawijaya University's Faculty of Administrative Sciences (FIA UB) lecturers have activities besides providing lectures on campus, like lecturers who carry out their activities for faculty and personal needs. It causes several problems, the first is that there are a queue and accumulation of work rather than those are who have the authority to allow the activities. The second problem is the submission of the draft assignment letter can only be submitted after the submission of activities has been approved by the authorized party to approve it. The third problem is that the Activity Applicant sometimes forgets to report the results of activities and bookkeeping of the Accountability Letter (SPJ). Problems that have been mentioned, can affect the faculty and department accreditation activities, if there are incomplete files when it is needed. Also, the dean and staff want to know the activities and the event rather than the lecturers. To solve the problems developed a system that purposes to manage and make it easier to submit activities until reporting. By referring to the Procedure Operating System (POS), it can help the development of the system that will be developed. The system involves 7 actors, the needs of elicitation are producing 37 functional needs. The tests in this system include unit testing, integration testing, validation testing and compatibility testing of the system. The benefits that can be received from the Applicant are the ease of submitting activities and draft assignments because they do not work twice. Also, the Deans and their staff will be easier to know the activities of the Lecturers at FIA UB.
