Abstract

In 2016, the first cause of death in the world was heart disease. It happened because heart disease was often detected late. Internet of Health Things (IoHT) is one of the technological developments of the IoT that can be used as a solution to the problem of electrocardiogram monitoring (ECG). The system consists of AD8232 ECG sensor that connected to an ESP32 sensor that has a BLE module to send the data that was obtained from sensor ECG to mobile middleware. BLE is one of the data transmission media that has advantages in the use of low power, low radiation that make the BLE is suitable to be used in human body. BLE is one of Low-Power Wide-Area-Network (LP-WAN) protocol that makes BLE suitable to be used in IoT environment. This research resulted in a measurement of the performance of the ESP32 BLE sensor node that is capable of processing and sending ECG data to mobile middleware with a delay of 4.02 seconds. So, the results didn't fulfill the requirements in ECG data transmission which is 4 seconds maximum for monitoring uses delay.

Abstract

Panorama Cibodas Residence is the author's residence located at Jalan Prabu Kian Santang, Kelurahan Sangiang Jaya, Kecamatan Periuk, Kota Tangerang. Based on direct observations by the author, Panorama Cibodas Residence has 3 security officers who carry out shift tasks in 3 shift, so that in 1 shift there is only 1 security officer on guard. The only 1 person security certainly will not be able to carry out whole residential area. If a crime occurs far from a security post, then it can't be dealt directly by security officers. So to maintain security at Panorama Cibodas Residence environment need help from the residents. In this research, the authors developed SKIP (Sistem Keamanan di Perumahan) application to report threats of crime in the Panorama Cibodas environment by developing Prototyping method to help residents maintain security in the Panorama Cibodas Residence. The prototype development method was chosen because the author's previously proposed the functional requirements of the application in the form of a prototype and then were shown to residents to get feedback until they got the final functional needs. Tests conducted on the SKIP (Sistem Keamanan di Perumahan) application is validation testing (blackbox), usability testing and compatibility testing. In validation testing results is 100% success rate. In usability testing results is 100% success rate for task execution by the respondent and has a final score on the System Usability Scale (SUS) 80 which falls into the grade B and adjectiva rating “good” category. In compatibility testing, SKIP application can run well on manual testing device and in automatically testing with Firebase Test Lab on the Android operating system version of minimum KitKat 4.4 with level API 19 and maximum Pie 9.0 with level API 28.

Abstract

Mobile Ad-hoc Network (MANET) is a network consisting of a collection of mobile nodes that function as routers for data transmission. The node communicates without relying on a fixed network infrastructure. One of the routing protocols on the network is DREAM which has characteristics in finding paths using the routing table. Mobile nodes are free to join and leave the networks at any times, thus leaving MANET vulnerable to attack. One of them is a wormhole attack that creates a link between two or more of nodes that affects routing performance. The study will be conducted using NS-2.35 to see the performance of the DREAM protocol in the presence of a wormhole attack based on the scenario of the number of nodes and variation of the wormhole node with a random waypoint mobility and random direction model. Parameters for testing include packet delivery ratio (PDR), end-to-end delay, routing overhead, and convergence time. The results show that increasing the number of node variations can affect evaluation metrics, while increasing the number of wormhole nodes is more stable. Testing with 3 pairs of wormhole nodes get the lowest packet delivery ratio of 11.975 % on 10 nodes with random direction mobility. The highest end-to-end delay result is 446,544 ms at 50 nodes with random direction mobility. The highest routing overhead result is 33.216% at 50 nodes with random waypoint mobility, and the highest convergence time result is 183,459 s at 50 nodes with random waypoint mobility.

Abstract

In IPv6 (Internet Protocol Version 6), fragmentation is only allowed on the end host side. As a result, IPv6 packets can experience potential failures in delivery. The potential failure is caused by two things. First, the packet size exceeds the MTU (Maximum Transmission Unit) value. Second, the router is configured by the network administrator to filter ICMPv6 Packet Too Big packets. Existing solutions are PMTUD (Path Maximum Transmission Unit Discovery), PLPMTUD (Packetization Layer Path Maximum Transmission Unit Discovery), and MSS (Maximum Segment Size) Clamping. However, these three solutions cannot be used in UDP (User Datagram Protocol) based communication and not all operating systems activate these features. Therefore, this research presents a solution by implementing socket programming through the case of audio streaming. With socket programming, research results show communication can take place well. This has been tested through several scenarios. In the first scenario, the results of the experiment without ICMPv6 Packet Too Big filtration and uniform MTU values are smooth communication with a small average packet loss below one percent. In the second scenario, the test results accompanied by ICMPv6 Packet Too Big filtration and MTU values are not uniformed are the same as in scenario one. The difference is that there is a pause as a result of the congestion control mechanism by the DCCP (Datagram Congestion Control Protocol) streaming protocol and limitation on socket buffer.

Abstract

Land use is a way to use land in carrying out certain objectives. Examples of land use types are forests, rice fields, housing, roads and rivers. However, the many transfers of land use functions, such as illegal logging of land used for housing development, require the use of land use planning. Given this issue, encouraging the writing of this research to assist land use planning by classification of land use types. The author uses two image features namely color features of 8 different color spaces (CMYK, HSV, HVC, Lab, RGB, YCbCr, YIQ, and YUV) and texture features using the Support Vector Machine classification method. The data used are 25 training data and 200 test data where the amount of data for each class is the same. The tests conducted are testing the color features with the highest accuracy, testing the texture features that affect accuracy, and the combination of color and texture features with the highest accuracy. The first test result is the color feature in the HSV color space has the highest accuracy of 98%. The second test result is the accuracy of texture features affected by image size, membership distance, and angle in the GLCM calculation. The image size of 900x900 with a membership distance of 1% and a combination of 4 corner features (0o, 45o, 90o, 135o) produces the highest accuracy of 96.5%. The third test result is a combination of color features in the CMYK, HSV, HVC, Lab, YCbCr, YIQ, and YUV spaces with the texture features of the second test results yielding the highest accuracy of 99.5%.
