Abstract

Message Queue Telemetry Transport - Sensor Network (MQTT-SN) is a communication protocol derived from the Message Queuing Telemetry Transport (MQTT) protocol that applied to the sensor network. To apply MQTT-SN requires Quality of Service (QoS). QoS is a method of measuring the quality of network and an attempt to define the characteristics and properties of a service so that messages are received. The Application of QoS in MQTT-SN is very important to ensure the receipt of data. This research implies QoS mechanism on Arduino Nano with NRF24L01 wireless communication using MQTT-SN message format. In this research is tested with different QoS level to get different result in each level of QoS. MQTT-SN with QoS level 0 allows packets not to reach the gateway because publishers continue to publish without any reciprocity from the gateway that make publishers don't know wether the message is delivered to the destination or not, and average accepted message 70%. While MQTT-SN with QOS level 1 the gateway can not distinguish publish data at the first time and next so duplicated messages can be happen until 30%. MQTT-SN with QoS level 2, the message is received exactly once due to temporary data storage on the gateway that make protocol will ignore data that is not needed and average accepted message 100%.

Abstract

Signature as a personal attribute is one of the person's identity verification equipment that is accepted widely by the society. The process of signature recognition starts from starts from preprocessing, which consist of filtering, thresholding, thinning, cropping and resizing. After preprocessing continued by feature extraction process using Geometric Invariant Moment to get the value of a feature that will be used for the classification process using K-Nearest Neighbour. The variations Geometric Invariant Moment feature that has the smallest of FAR value and FRR value on each data source are different. For data from Indonesia the smallest FAR obtained while using moment 7 with value is 7% and the smallest FRR obtained while combining moment 1,2,3,6 and 7 and using all of the moment with each value is 61.5%. For data from Spain the smallest FAR obtained while combining moment 3,4,5 and 7, moment 1,3,4,5 and 7 and combining 1,3,4,5,6 and 7 with each value is 7% and the smallest FRR obtained while combining moment 2,3,4,5,6 and 7 and using all of the moment with each value is 72%. For data from Persia the smallest FAR obtained while combining moment 3 and 5 and combining moment 3,5 and 6 with each value is 9.5% and the the smallest FRR obtained while combining moment 1,2,3,4,6 and 7 with value is 37%. The testing results of FAR and FRR is inversely proportional. The system can recoginize the fake signatures well that proven by getting FAR value is relatively small on all of data sources. But the system can't recognize the original signatures well that proven by getting the high FRR value on all data sources. Features of Geometric Invariant Moment that applied globally on an image don't provide high accuracy. Perhaps, it happened because when apply global feature, the local features can't recognize properly. It occurs on the original signature image, while the application of the features of Geometric Invariant globally on the fake signature image provide high accuracy.

Abstract

XYZ Bank is a banking company with head office in Jakarta. The employment service business process for leave, overtime, and update of employee data at Bank XYZ still rely on paper based, so that the HC area unit (Human Capital) must manually input recap data into SAP (Employee Administration System). HC area unit employees will be particularly vulnerable to input errors that can be fatal for employee salary calculations. The implementation of paper based on some activities of leave, overtime, and data update also cause the process runs less efficient and effective so that the processing time becomes longer. The method used in doing business process improvement refers to the framework of ITIL v3 domain service design. The result of the business process improvement of XYZ staffing service business for leave is an average time acceleration of 58.11 minutes due to loss of PIC (Person in Charge) activity in requesting and submitting the leave leave form, as well as equalization of utilization to superiors, employees and HC area due to loss of role PIC and courier. In the employee overtime business process, the average acceleration time of 370.98 minutes due to loss of PIC's role in manual recording, as well as equitable distribution of employers, officers, and HC areas due to loss of PIC and messenger role. In the business process update employee data there is an acceleration of 22.6 minutes due to loss of activity provide the form and input employee data, and there is a change in resource utilization percentage due to reduced HC area activity.

Abstract

Software Defined Network (SDN) is network modeling that separates between control plane and data plane using Openflow protocol communication standard to connect both of them. SDN began to developed in recent years and has been widely implemented, one of them is network routing. There are two routing algorithms in this research which are Dijkstra and Floyd-Warshall. Both of these algorithms will be implemented using Mininet emulator and Ryu controller. Tests that performed in this research include parameters such convergence time, throughput, link failure, and resource usage. The result of convergence time test from this research showed Dijkstra's is superior to average of about 9,08-16,03milliseconds compared with the Floyd-Warshall with average of about 14,51-38,63milliseconds. Based on the results of throughput testing, both algorithms do not have significant differences. The Floyd-Warshall had an average throughput of 12.7-29.54Gbps while Dijkstra's had an average of about 12.89-29.22Gbps. For the test results from the Link failure, Floyd-Warshall is superior because it had a faster recovery time with average about 30.34-38.51seconds compared to Dijkstra's with average of 37.65-44.92seconds. Usage resource test showed that memory usage measurements for both algorithms share same memory, but CPU usage measurements showed the Floyd-Warshall consumes more CPU power compared to Dijkstra's.

Abstract

Signature have been widely accepted by people as one of many tools that used to verify a person's identity. Signature verification is highly needed in order to avoid crimes regarding signature's validity. The process of signature image verification uses feature extraction based on Pyramid Histogram of Oriented Gradient (PHOG) for extracting feature from global to local image area that used for the next process, classification using K-Nearest Neighbor method. There are some parameters that can affect the feature extraction of PHOG and K-NN as classification method such as number of bin, level, range of angles, and K. As for the additional parameters, namely the amount of training data that affect the overall results of the classification used. Feature extraction and classification by the method with the best parameter values and training data used produces the highest accuracy of 99.5% on Indonesian original signature data and 98.5% on the data of the Persian original signatures. While the forgery signatures data produces accuray only as much as 56% on data from Indonesia and 35,5% on data from Persian. Results from tests show that the algorithm is not good enough for distinguishing forgery signature that has high similarity with genuine signature even it is works well for recognizing genuine signature.
