Abstract

Salah satu faktor penting yang berpengaruh terhadap kesuksesan perikanan budidaya adalah aspek kualitas air kolam yang tergambar pada beberapa parameter fisik antara lain suhu, derajat keasaman (pH), oksigen terlarut maupun kekeruhan air. Sebagai tempat hidup ikan, perubahan parameter fisik tersebut dapat berpengaruh secara langsung terhadap pertumbuhan dan daya tahan ikan budidaya. Oleh karena itu, peternak perlu melakukan pengamatan berkala terhadap kondisi air kolam budidaya untuk kemudian memberikan perlakuan tertentu agar kondisi air tetap sesuai dengan prasyarat tumbuh kembang ikan yang dibudidayakan. Peternak ikan dapat melakukan pengamatan kondisi air dengan mengambil sampel air kolam untuk kemudian diamati di laboratorium atau menggunakan peralatan sensor. Mekanisme tersebut memerlukan kehadiran peternak secara periodik pada kolam budidaya. Hal ini tentu dapat menyulitkan peternak apalagi jika ukuran kolam budidaya cukup luas. Lebih jauh lagi, kondisi fisik air dapat berubah dalam waktu yang relatif cepat, terutama karena adanya polutan baik  polutan eksternal maupun internal. Pada penelitian ini dibangun sebuah sistem pemantauan kualitas air kolam budidaya ikan secara real time menggunakan jaringan sensor nirkabel. Sistem yang diusulkan terdiri atas tiga bagian, yaitu : kumpulan perangkat node sensor, perangkat gateway dan data center. Secara periodik perangkat node sensor   mengukur parameter  fisik air menggunakan sensor dan mengirimkannya ke perangkat gateway. Perangkat gateway kemudian mengirimkan data tersebut ke data center untuk kemudian disimpan dan diolah.  Peternak dapat mengamati kondisi air kolam budidaya secara real time dari sebuah aplikasi berbasis web. Untuk melakukan validasi terhadap sistem yang dibangun, pengujian fungsionalitas dan kinerja dilakukan. Hasilnya menunjukkan bahwa sistem mampu merespons perubahan pada kondisi air seperti, tingkat kejernihan, pH, O2 terlarut dan temperatur. Sedangkan pada pengujian kinerja diperoleh hasil terbaik pada jarak 40 meter dengan besar paket 82 byte yang memberikan nilai hasil pengujian sebesar 189,4ms untuk delay dan 7,8% packetloss.Abstract The water physical condition including water temperature, acidity level (pH) and dissolved oxygen level play an important role in the success of aquaculture. As the habitat of the fish, the changes of physical parameter in water gives a direct impact to the growth and vitality of the fish. Therefore, fish farmer needs to periodically observe that water condition and takes an immediate action upon any changes. At present, the fish farmer can perform a water monitoring by taking a water sample and observe it in laboratory. However, this method can be inefficient since the water condition can be changed rapidly due to the polutant intervention either from external or internal. Therefore, in this paper, we propose a real time aquaculture water monitoring system using wireless sensor network. The proposed system can be composed into three main components : node sensors, gateway device and data center. Periodically, each node sensor measure the physical parameter of water using its sensing device and send those data to the gateway using LoRa communication module. The gateway then relays the sensor data to the datacenter using Restful Webservice protocol. Based on the functional evaluation the proposed system can give the proper response on the changes of the water quality in term of turbidity, acidity level, dissolved oxygen and temperature. Furthermore, from the network performance testing, we observe that the delay is 189.4ms and the packetloss is 7.8%.

Abstract

Pada bidang pertanian, Internet of Things (IoT) digunakan untuk mengendalikan sensor pertanian dan menghubungkannya dengan infrastruktur cloud dengan tujuan untuk menunjang pertanian presisi. Salah satu tantangan dalam penerapan IoT dalam pertanian presisi adalah keberagaman aplikasi dan protokol komunikasi di tengah keterbatasan sumber daya perangkat sensor yang digunakan. Ketergantungan library dan versi program yang saling kontradiktif mendorong diperlukannya terobosan baru dalam implementasi aplikasi sensor atau gateway pertanian presisi. Pada penelitian ini penulis mengimplementasikan virtualisasi berbasis kontainer untuk perangkat IoT pada pertanian presisi yang memudahkan pengimplementasian program pada satu perangkat tanpa mengurangi kinerja dari perangkat IoT. Program virtualisasi yang kami gunakan adalah Docker yang diimplementasikan ke dalam perangkat gateway IoT berupa Raspberry Pi. Hasil penelitian ini membuktikan bahwa penggunaan Docker, tidak menurunkan kinerja Raspberry Pi. Sehingga penggunaan Docker pada infrastruktur IoT pertanian presisi sangat mungkin untuk dilakukan karena memberikan keuntungan berupa kemudahan dalam implementasi, update, dan pengisolasian proses.

Abstract

Nowadays, there has been a great traffic in the network. It is characterized by an increasingly high users will increase the complexity of the network such as increased server load and hard to configure any devices from different vendorss, so there needs to be a good web server. If a single web server, it will cause SPOF (Single Point of Failure). The use of cluster servers with load balancing will improve the performance of web servers implemented in Software Defined Network. Load balancing with resource-based methods is a load-sharing method using the smallest CPU usage of the server as a reference. Through the implementation of the system obtained server divide the load well. Testing with many connections and rate divided into 3 parts that is low to rate 40, medium to rate 80 and high for rate 160. The testing parameters used are throughput, response time, and CPU usage using Httperf and psutil tools. The results of the test obtained with the average throughput value of 947.9 KB / s, response time average of 6.2 ms, and CPU Usage of 59.82% on the first server, 69.73% on the second server and 93,24% on the third server. By comparison of the Round Robin algorithm, the CPU-based method is better than Round Robin based on the tests performed.

Abstract

The development of internet technology whom the users desire for the availaible services anytime tend to be increased following the current development which commonly not always supported by the increasing adequate server services. The highest users demand make the work load in server raised rapidly which cause down server in a short period along with the needs of technology which handle the utilization of complex connections. As a new technology, Software defined network offers scalability and programmability for the using of connections which become complex such as Balancing Web Server. There are some studies concerning with load balancing in Software defined network (SDN) with various algorithm which is applied will resulted difference performance from algorithm, , one of them is Round robin and Least connection. The experiment is done with 3 categories; low, medium, and high. The experiments parameter which is used are Throughput, Response time, and CPU Usage use Httperf and Psutil. Round robin Algorithm is more excellent than Least connection Algorithm in a tiny connection. On the other hand, for the bigger connection, Least connection Algorithm is excellent. The average value of time response shows the superiority of Round robin Algorithm rather than Least connection Algorithm. CPU Usage server with the Round robin Algorithm is more stable in each rate category. On the contrary, Least connection Algorithm is less of load than Round robin Algorithm in spite of the value is raise in each rate category.

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

Virtualization is the process of creating forms in virtual versions of operating systems, networks and others that can run applications like physical devices. Resources in virtualization become an important factor to support server performance. Sometimes resources are not fully utilized when resource allocation remains. As a result, when the server requires more resources, unused memory allocations can not be used. With memory allocation, the system can manage memory usage to maintain and improve server performance that can sometimes change. Application of memory allocation can be facilitated by algorithm and k-means regression method to predict the use of memory resources. To that end, the authors have implemented a dynamic memory allocation system on computer-based k-means clustering system. From the test results, the system is able to make changes in the form of upgrades and downgrades with the help of tools Apache Jmeter with time 2.5 seconds. Based on the results of tests that have been done, hypervisor successfully upgraded at 36.5699 seconds from 1 GB to 2 GB. Then second to 153.1348 hypervisor upgrade again from 2 GB to 4 GB. After the request to the server stops, the hypervisor downgrades the seconds to 611.709 from 4 GB to 2 GB then downgrade again in seconds to 624.4994 from 2 GB to 1 GB.

The IoT device number of use also increase, from this fact, IoT devices management become the challenge to solve. The solution of this challenge is network monitoring system that run effectively. The system must handle the constraint of IoT device power and computational performance too. The implementation of monitoring using SNMP is not effective, because the size of paket for transmission is big and not all component of SNMP protocol being used. The monitoring system that being developed use UDP protocol because of its simplicity and light-weight to IoT devices. The selection of data structure and database also give contribution to effectiveness of this system. The IoT devices that used for the development is Raspberry Pi, this device has been selected because of the good integration with the other sensors, so it will make the development of this system in future become possible. This system monitors the device resource and network activity, then the result will be displayed on a graph, so the user can get the information of the result. The network monitoring system that being developed is effective, because the use of device's resource is small. In one transaction, the data paket size which transmitted is 309 bytes, this is smaller than SNMP-based monitoring system.

Abstract

The rapid network growth resulted in SDN Networks will encounter heavy traffic or network traffic from various types of data packets. The density of network traffic and the different data packets will result in decreased network quality. This is due to differences in data packets that flood the network has different communication characteristics as well as the Transmission Control Protocol (TCP) packet and the User Datagram Protocol (UDP) package. The more dense and the difference of packet characteristics on network traffic, it is necessary to implement network slicing by using flowvisor to overcome the problem of decreasing SDN network performance. Through the implementation of this system obtained QOS test results throuhput TCP, throughput UDP, packet loss, and jitter. Implementation of network slicing with flowvisor has a distance average value of TCP and UDP througput better than the normal SDN network that is 380.359 and 0.535 Mbits / sec. The mean distance of packet loss and jitter value of network slicing implementation also has better value than normal SDN network that is 908,546 bytes on packet loss and 0.138 ms on jitter.
