Abstract

Learning evaluation using multiple choice question paper is widely used because it is more effective at measuring learning outcomes and can cover more subjects. In 2017, there was a research to build multiple choice exam question bank management system at Faculty of Computer Science Brawijaya University. This research helps to reduce the possibility of similar question being proposed by different lecturers. However the research was not able to generate multiple choice question paper. The Course Lecturer Coordinator must select the questions one by one at question bank to generate a question paper. The question paper made by Course Lecturer Coordinator must meet the learning outcomes that have been set at the beginning of semester. Therefore, the question paper must have topics and question difficulty level which corresponds to the learning outcomes. This made it difficult to generate question paper. A web-based randomized multiple choice question paper generation system was developed to resolve this problem. The system development was done with waterfall software development model using object-oriented approach. This system had been tested using unit, integration, and validation testing. White-box testing was used in unit and integration testing, while black-box testing was used in validation testing. All of the tests performed to the system shows valid results.

Abstract

information regarding train travel routes has not been clearly recorded while at the station or leaving the station, this causes passengers to experience confusion to find that information. The application of RFID technology in every station that is passed by the train will get real-time and Web-based information. So that passengers feel more comfortable to have the history of train travel and the leadership of the station can calculate the time of arrival of each train are seen on the website. The RFID tags installed on the locomotive stores the information needed, which is the train ID, destination, previous station, current station, and next station. After identification, the information will be recorded automatically in a database, then the information on the RFID tag will be updated according to the next trip. The information is also used to move the Wessel automatically according to the destination to be addressed. This system applies a Wireless Sensor Node by using NRF24L01 as a communication module. The RFID-RC522 module was chosen because not only can it be used to identify RFID tags, but it can also perform writing modes to block data on the RFID Tag. The interface used consists of a desktop-based interface that is used when wanting to update information on RFID Tags and a web-based interface is used to display information about train travel history in real-time. There are two tests on this system, namely functional testing and performance testing. In functional testing, the base station can communicate with sensor nodes and actuators, sensor nodes can identify and update data on RFID tags, actuators work according to commands given by the base station, then the base station can perform automatic updates to the database. Performance testing is measured by sending delay parameters between nodes in each process. The results of testing when identifying an average delay of 63,875ms, when updating information received an average delay of 44,625ms, and testing on the branching path got an average delay of 21.5ms.

Abstract

Malang City besides being famous as a student city is also famous as a tourism city because of its beautiful nature. So do not be surprised if many immigrants settled in the city of Malang. Hinduism as one of the religions in Malang has a population of 0.16% of the population of Malang City. Hinduism has a place of worship which is usually called a temple. In the city of Malang there are five temples which are places of worship for Hindus. The small spread of temples in the city of Malang causes people to find difficulties in finding the closest temple location, especially for migrants. To overcome these problems, the solution offered is to develop an information and temple search application based on the nearest location in Malang based on Android. This application is expected to be able to inform the location of the closest temple, provide the closest route to the temple, and provide information related to the name and telephone number of the temple's organizer, the piodalan day, and the temple worship schedule. In its development, this application was designed using the Object Oriented Design (OOD) approach and implemented with the Object Oriented Programming (OOP) method. Unit testing of three main application methods yields a valid status. The results of validation testing conducted on five test cases produce valid status. The usability test results on five respondents resulted in an SUS 84 score that was included in an excellent scale.

Abstract

Emotion is a feeling of a person's feelings that can influence a person's decision to act and behave. The most recognizable and identifiable expressions of a person's emotions are facial expressions. Research related to emotion recognition based facial expressions is relatively new research and its application is comprehensive in various fields such as academia, industry, and government. Emotion recognition requires a classification method capable of recognizing the type of emotion of each facial expression and a feature selection method to select optimal features. Therefore, this study will classify emotions based on facial expressions by implementing the Extreme Learning Machine (ELM) method as a classification method and Genetic Algorithm (GA) to select the most optimal features. Based on implementation and analysis, the average accuracy by the ELM and Genetic Algorithm is 82,87879% with the number of generations = 22, population size = 70, crossover rate = 0,8, mutation rate = 0,2, and the number of hidden neurons = 40. These results were compared with the ELM method without Genetic Algorithm which implies an average accuracy of 72,12121%. The accuracy results obtained from the two methods show that the feature selection using Genetic Algorithm has succeeded in increasing the average accuracy generated by ELM by 10,75758%. Genetic Algorithm is moreover succeeded in selecting features with an average of 63 selected features from a total of 136 features.

Abstract

Wireless Sensor Network has been able to be applied in agriculture to monitor the condition of agricultural land, namely regarding the humidity, pH, and temperature of the soil. However, this monitoring process cannot take pictures on the location because Wireless Sensor Network has the disadvantage of not being able to send large datas. To solve this problem, you can use a large capacity communication module so that more data is sent and also use the compression method for data to reduce the size of data before being sent. The communication module used in this study is 6LoWPAN. 6LoWPAN was chosen because it has advantages in terms of transmission capacity, range and has a low power consumption. There are 2 compression methods used, namely the DCT algorithm which is used to reduce interpixel redundancy and RLE to condense the results of the DCT algorithm so it can be smaller. The results obtained after testing are that the application of the compression method can save image size by around 24% from the size of the original image and reduce the total package sent by about 77% of the original packet. Delivery performance using the compression method has the advantage of sending time but decreases the success rate and increases average delay when sending image data.
