Testing and Implementation of OpenFlow Switch on Software Defined Network
Software Defined Network is deemed to be the networking architecture for the future. But SDN requires new network devices for its infrastructure called whitebox switches. Because SDN is still in development period, SDN whitebox switches are notoriously expensive to produce. But there is an alternative to create a full-fledged for a fraction of a cost called Open vSwitch, which is a software based conceptual whitebox switch that can be installed in a computer to simulate whitebox switch with its network card as the switches’ ports. Open vSwitch can be installed to Single Board Computer with five-to six network ports to create a whitebox switch. One of the best single board computer to use is Banana Pi R1, which is an ARM-based SBC with 5 ethernet port in the form of Distributed Switch Architecture. With a little bit of VLAN knowledge, the distributed switch can be treated as real ethernet port. Open vSwitch then can be installed in Banana Pi R1 to create a whitebox switch in about Rp. 1.200.000 or about $85.

Design and Implementation of Passive Direction Finding System 1,09 GHz by using Modified 4×4 Butler Matrix
Passive radar is a system for detecting target without transmitting electromagnetic signal. The advantage of using this radar is the ability to detect target without being detected or “too see without being seen.” One of the abilities required by the passive radar is the ability to determine the direction of transmitter or known as direction finding. In this final assignment, a 4×4 butler matrix was designed for the implementation of passive direction finding system. The design and simulation process of the butler matrix was started by designing and doing simulation at the software. To maximize the result, modification and design optimization were also carried out. After the results of the simulation fulfill the specifications, butler matrix would be fabricated and measured as well as tested. The system was implemented at FR-4 epoxy substrate. The process of beam forming was successfully implemented by feeding every input port of butler matrix connected to the circular array antenna to produce target incoming angle. To test the system, artificial transmission signal was radiated at work frequency of 1090 MHz at far field of the antenna and the sytem would be able to detect the incoming angle of transmitting antenna.

Software Defined Network (SDN) Configuration Application with OpenDaylight Platform
Internet has been a part of emerging technologies, such as cloud computing, virtualization computing, data center, and big data services. These technologies need adaptive environment since legacy configuration cannot change the network characteristic quickly. This legacy process has some ordered steps. To solve these problems, came up an idea named Software Defined Network. SDN uses an application or program to configure the network. Applications are designed to do functions in the network. SDN application is connected with an SDN Controller. Then, the controller will send the configuration for each whitebox switch using the OpenFlow protocol. The controller configuration is performed based on the application / program function. In this thesis, the application uses a web framework called Flask with the data structure from OpenDaylight controller. The main function of this application is to manage device’s flow. An admin can build a flow and remove it from the device. Download and upload features are also provided for main function support. If an admin has already built the configuration, the admin can reuse the configuration by downloading it first. In the end, the application is tested with some cases in order to show the utility of each feature.

Sensor Data Detection and Transference Modules in Ambient Assisted Living System: Monitoring of Elderly’s Condition Using Smart Devices
Indonesia is a very populous country with headcount as big as 260 million people, and 8.9% of the population consists of elders. Each year, the number climbs up and is predicted to be one with the highest population of elders in Asia and globally by the year 2050. The significant growth also means there would be a push in demand where their quality of life becomes the focus, especially in the aspect of health-related needs. On the other hand, technology has entered the Industry 4.0 era where automation and data exchange becomes the norm to be utilized in increasing people’s quality of life. Seeing the gap between the problem and the opportunity presented, the concept of Ambient Assisted Living (AAL) is formed where connected technology is applied to help elders in becoming more independent and thus increasing their quality of life. In this capstone project, an AAL system is designed to monitor elders’ condition using smart devices that consist of smartwatch and smartphone. To enable the process, accelerometer and heart rate sensor are being utilized at 200,000 microseconds sampling rate so that the data generated would be sent to the device where the further process would be triggered. Data synchronization between the elders’ smartwatch and smartphone is set up by benefitting from the Wearable Data Layer API of Google Play Services. Based on the implementation results, there are some aspects that can be improved; one of them is the accuracy where data loss still occurs with the receiving percentage of acceleration data is as small as 1.7% and heart rate data is 67.5%, and to push for minimum delay as the current synchronization delay time is 2.5 seconds.

In testing the voice modem that will be used in digital radio communication system, we need multipath fading channel simulator to simulate the condition and effect of multipath fading channel in real-time. One alternative to implementing voice modem and fading multipath channel simulator is using Digital Signal Processor (DSP), not only for real-time implementation but also ease in the development of signal processing algorithm.
In this final project, multipath fading channel simulator for DSP based voice modem using DSK TMS320C6713 has been successfully implemented. This final project will tell you about design, development of algorithm and implementation of fading multipath channel simulator. The data transfer mechanism used is frame based with the triple buffering method.
Several simulations have been done to test the prototype of multipath fading channel such as testing of probability density function (pdf) histogram for Rayleigh fading signal, testing of real-time processing using sinusoidal, BPSK and speech signal as the input. We found that the pdf histogram of the Rayleigh fading signal that has been generated using Clarke’s method, approximate the distribution theoretically. From the computation, we know that the channel is slow fading and frequency selective fading.

Implementation of Devops in Building and Maintenance Software Defnied Storage System Based on Ceph
Data storage technology is very important in this day and age. The rapidly growing data usage requires data storage technologies with capabilities that can cope with the rapidly growing size of huge data. The size of the data is something to consider, but the ability of a system that can be installed on any type of data storage device will be much needed. The most important thing in a data storage system is a technology that can store data without worry the data will be lost if there is a failure on a data storage system. In this Final Project conducted research and implementation of a data storage system using Ceph software as backend data storage. Using Ceph, a system can properly address problems arising from the growing data. Ceph can distribute data to all devices that are in a system called the Ceph cluster so that the data is not easily lost when there is a failure on the system. Ceph can run on all data storage devices regardless of proprietary brands or devices, so the system can run even with everyday devices. This Final Project also discusses how the Ceph cluster can be installed using an automation technology with Ansible. Use of Ansible can cut the time it takes for the installation of a Ceph cluster to 60% so that an administrator can save time to do other important things. Automation technology will also be applied to client-cluster interactions using file storage and block storage services using Samba, iSCSI, and Nextcloud.

Design and Implementation Microstrip Log Periodic Dipole Array Antenna for Passive Coherent Location and Passive Direction Finding System
Passive radar is a type of radar that can detect the existence of target by utilizing signals from other transmitters so it is not easily detected by the target. There are several types of passive radar, some of them are Passive Coherent Location (PCL) radar that serves to determine the bistatic range and Doppler-shift of the target and Passive Direction Finding (PDF) radar that serves to determine the arrival angle of the target.
In this final project Log Periodic Dipole Array (LPDA) antenna has been designed for the implementation of PCL and PDF systems. This antenna is designed to capture TV signals at UHF frequencies and ADS-B signals on L bands. The design begins with the simulation followed by optimizing the size of the antenna to get the desired specifications. Once designed, the antenna is fabricated as many as four pieces.
The research continued by measuring antenna parameters. Based on the measurement results, it was found that the operating frequency of the antenna is 682 to 1600 MHz with the smallest return loss value at the frequency of 1540 MHz is -47.6 dB. In addition, a VSWR antenna is rate less than 2 at a frequency of 682 to 1600 MHz. The minimum VSWR value is at the 1.54 GHz frequency that is 1.01.
The fabricated LPDA antennas are used as receivers in PCL and PDF systems. The PDF system used four antennas arranged in different directions. While the PCL system uses two antennas used as antenna surveillance and antenna reference.

In addition to that, Ceph has the ability to distribute data evenly on all storage system devices, so the data is not easy to lose if there are problems on the system. This Final Project also discusses the process of optimization of Ceph-based data storage system to obtain optimal system performance with the limitations that exist during the work of this final project. Optimization process is done by determining the factors required by the system which will be then breakdown into parameters to be tested to determine the design of systems that have optimum performance. Ceph-based data storage system that has the optimal performance in this Final Project was obtained by designing data storage system that has 9 OSD, using BlueStore as its storage backend, and using two types of network that is cluster network and public network. Keywords: Ceph, CRUSH, optimization, OSD, cluster network, BlueStore
Fall, Overworked Condition, and Heart Rate Abnormality Detection in Ambient Assisted Living System: Monitoring of Elderly Condition using Smart Devices
Each year, the aging population in Indonesia keeps increasing. In 2050, the number of aging population in Indonesia is predicted to be larger than the aging population in Asia and the world. This rapid increasement should be adjusted with a suitable method to increase the living quality of the aging population. Today, technological development has entered the stage of Industry 4.0, resulting in a technology that could realize a high quality elderly by providing technological assistance to live independently. This technology is called Ambient Assisted Living (AAL). In this paper, an AAL system that could automatically detect emergency conditions in elderly people, such as fall, overworked condition, and heart rate abnormality, using smartwatch and smartphone devices was developed. Using an acceleration sensor in the smartwatch, a fall detection system was developed with vertical acceleration as the main parameter and a threshold of 38 m/s2. In addition, overworked condition and heart rate abnormality detection in elderly people was developed using the heart rate sensor in smartwatch as well as the result of an activity identification system. Activity Index (AI), which is a total of standard deviations of the accelerations detected within a one minute time interval, is used as the main parameter for the activity identification system. Other than detecting emergency conditions, the system developed could also inform the family immediately when those conditions occurred to the elderly. The emergency condition information is given to the family through a notification from an AAL application installed in their smartphones. By testing to non elderly people, the fall detection accuracy was obtained at 73.33%. Furthermore, the functionality of the overworked condition detection, heart rate abnormality detection, and notification feature has been tested to be working well.
