Abstract

Fingerprint scanner's presence infrastructure is a system that is widely applied as a presence today such as the Faculty of Computer Science (FILKOM). The presence system using a fingerprint scanner can help staff for recording attendance data, as well as calculating the performance of the employee. However, there are problems that arise from using the fingerprint scanners as a presence system, including the presence of attendance recapitulation which is still manualy calculate, asynchronous employee attendance with attendees result, transparency of the attendance data is unknown by the employee. The solution to this problem is to make each civitas have a tool that is used to make a presence, so that the presence can be done by the civitas themselves and attendance data can be directly obtained by staffing staff. From this solution a system was developed to use a smartphone as a media presence because this device is owned by each civitas, sensors owned by smartphone devices are also complete such as WIFI sensors, fingerprints and cameras. The author develops an Android mobile-based system as a presence by utilizing fingerprint sensor, camera and WIFI. WIFI is used as a virtual fence so that the community who wants to attend must be present in the FILKOM environment, the development of this system carries the REST API technology that is useful as a bridge between mobile presence data and computer staffing staff used as a recapitulation tool for community attendance. This presence system was developed with the software development life cycle, which is the waterfall method where needs have been defined at the beginning and there is no change until the design, implementation, and testing process of the system has been developed. Tests carried out include: unit testing on four methods with valid results, validation testing on 38 functional requirements with all valid results, integration testing by checking the interaction of two methods with valid results, and compatibility testing using three devices with valid results. From the test results obtained by the system developed has met the requirements that have been determined, for the appropriate system, valid results and running on Android devices version of Lollipop to Pie

Abstract

Superior varieties are important supporting component in increasing national rice production. Each type of superior variety has different characteristics. Farmers need knowledge to be able to choose the type of rice they want while keeping rice production stable. To overcome the problem in determining rice seeds, one solution is to use data mining classification. The classification are using the decision tree method, with the C4.5 algorithm. C4.5 algorithm is an algorithm that builds decision trees from data with recursive patterns. C4.5 goes to each node of the decision tree, then selects the optimal branch until no more branches are generated. the algorithm can produce a classification of superior rice varieties needed to be planted in the fields. This research has input data in the form of flag leaves, grain shape, grain color, rice texture and texture. The input data is then processed by the C4.5 algorithm to produce outcomes that determine superior varieties of rice. The results of this study indicate that the classification performance of superior rice varieties is more influenced by the grain form attributes compared to other attributes. Meanwhile, the accuracy of the highest C4.5 algorithm in the k-fold 1 calculation was 28.571%. Meanwhile, k-fold 2 was 17.857%, k-fold 3 was 10.344% and k-fold 4 was 10.714%.

Abstract

Healthcare is one of the interesting fields in the application of IoT. However, the devices used in the implementation of IoT-based healthcare are very heterogeneous, this is a challenge for application developers to overcome the different communication mechanisms in sensing devices. In addition, the IoT application requires batch and stream data processing. Based on these challenges and requirements, the authors develop middleware to overcome these challenges. Middleware consists of three components it is sensor-to-cloud gateway components, messaging services, and data access interfaces. After implementation we perform device management, sensor-to-cloud gateway, messaging service, batch interface and stream interface test. Device management testing shows that the gateway component is able to manage sensor devices using BLE. Sensor-to-cloud gateway testing shows the ability of the gateway to forward sensor device data to the cloud. The messaging service test shows the ability of middleware to store messages in a database and facilitate the access stream interface. In batch and stream testing it can be seen that middleware can provide data for client users in batch and stream.

Abstract

The success of the software depends on the selection of needs that are prioritized properly. Priority needs are considered as one of the most important approaches in the process of needs engineering. needs prioritization is used to determine the bookings or the schedules to carry out the needs based on their priorities or interests with respect to the stakeholders' point of view. There are various techniques and methods that have been proposed by the researchers. In this study, the researcher applies the priority method proposed by Jim Azar, Randy K. Smith, and David Cordes to prioritized the software needs which only use a core business value. The Value-Oriented method Prioritization is a method that emphasizes the main business value in the process of determining the priority, using an ordinal scale according to how important the business in the company is. the risk of the business carried on by the company is also identified and given a positive value for weighting the business core, while a negative value for weighting the risk. This application has been tested for functional and non functional requirements, functional requirements using black-box testing, namely validation testing, and white box testing, namely unit testing and integration and non functional requirements using compatibility testing with the help of sortsite software with the result of not getting critical issues in many browsers and acuuracy testing, so it can be concluded that it gets a valid results.

Abstract

The queues that occur when making toll road payments are still a problem in Indonesia, one of which is the problem because there is no system that automatically classifies vehicles passing on the toll road, so that large vehicles such as trucks that are divided into 5 classes must be manually differentiated by toll gate officers. One effort to overcome these problems, in this study a system was designed to be able to automatically classify vehicles passing the toll road into 5 classes according to the class applicable to the Indonesian toll road, so the classification process that was previously done manually can be done automatically, this of course bring benefits to the payment transaction time for each vehicle that is getting shorter, which in turn can reduce the potential for congestion that occurs at the toll gate. This system works based on image processing, the classification process begins with vehicle video capture using a webcam, then the vehicle video is processed on Raspberry Pi 3 to extract image features from the vehicle using the Histogram of Oriented Gradients (HOG) method, then the features obtained are processed The classification uses the k-Nearest Neighbors (k-NN) method to determine the class of vehicle, then results of the classification are displayed on the LCD screen. From the tests conducted on the system using 25 test data, with each class as many as 5 test data, the results obtained for system accuracy in class 1 by 80%, class 2 by 80%, class 3 by 60%, class 4 by 60%, and class 5 by 60% .

Abstract

Brawijaya Smart School High School has various types of student achievement. However, among the various types of achievement, there were no achievement that used Academic and Non-Academic aspects as a main reference in the selection. Teachers find it difficult to use Academic and Non-Academic value data due to the nature of the two values. Based on existing problems, a system is needed that is able to process combined data of Academic and Non-Academic value to determine outstanding students based on these two aspects. K-Nearest Neighbor (KNN) is a data mining algorithm that can be used for the classification process of outstanding students. As for the sorting of the classification results with many attributes, Simple Additive Weighting (SAW) algorithm is used. The attribute used consists of the average grade of students from semester 1-5 and students plus poin. The validation test produce a score of 100% Valid. The output of this study is a system that can provide recommendations of outstanding students by implementing the website-based KNN and SAW algorithm. And the results of the User Acceptance Testing (UAT) has a value of 86%.

Abstract

Humans can carry out their work in a healthy condition, so health is the most important thing in life. But many people are unable to do their jobs due to physical limitations, commonly called persons with disabilities. Biomedical engineering is medical science that uses medical science and design engineers to solve health problems. Electromyograhy (EMG), one of the biomedical sciences that can detect signals generated by contractions in muscles, using EMG can make the system of detecting signals of muscle contractions, especially in the arm muscles. This system will help detect arm muscle contractions for people with disabilities in the arms. Detection is performed on changes in the degree of the arm, the degrees detected are 0, 30, 60, 90, 120, 150, and 180 degrees. Signals received by EMG have noise that can interfere with detection, so signal refining is required in the form of an exponential moving average (EMA) method. Exponential moving average has a weighting value to make a reward, the value used is 0.1 and 0.3. After refining the signal, the detection of degree changes is performed using the decision tree classification method. Then the results of the classification will be displayed on the LED and LCD.
