Judul: Implementation and Performance analysis of openflow switch and conventional switch in computer networking
Abstrak: OpenFlow merupakan teknologi baru pada jaringan komputer, khususnya teknologi switching. Tujuan penelitian ini adalah untuk mengimplementasikan dan melakukan analisis kinerja terhadap switch OpenFlow dan switch konvensional pada jaringan komputer. Metode pengukuran kinerja kedua switch menggunakan nilai maksimum bandwidth. Bandwidth diukur terhadap paket UDP dengan default port 5001 pada pengujian berurut dari 10-100 Mbps.Pengambilan data dilakukan selama 10 kali pengukuran tiap satu skenario pengujian. Tiap skenario pengujian dilakukan pengulangan sebanyak 5 kali agar data yang dihasilkan lebih valid. Hasil penelitian menunjukkan switch OpenFlow memiliki nilai rataan bandwidth switch OpenFlow sebesar 37.14 Mbps dan pada switch konvensional sebesar 31.97 Mbps. Nilai rataan jitter pada switch OpenFlow sebesar 0.253 ms dan pada switch konvensional sebesar 0.309 ms. Nilai rataan datagram loss pada switch OpenFlow sebesar 0.10% dan nilai datagram loss pada switch konvensional sebesar 0.40%. Berdasarkan hasil penelitian yang telah dilakukan, switch OpenFlow memiliki kinerja yang lebih baik dibandingkan dengan switch konvensional, OpenFlow is a new technology on computer networks, especially switching technology. The purpose of this study is to implement and analyze the performance of OpenFlow switch and conventional switch on the computer network. The maximum bandwidth value was used as the method for measuring the performance of the two switches. Bandwidth was measured on the default port UDP packets 5001 with values between 10-100 Mbps. Data collection was performed 10 times for each of the test scenarios. Each test scenario was repeated 5 times so that the data generated is valid. The results showed that the bandwidth average value of OpenFlow switch was 37.14 Mbps and conventional switch was 31.97 Mbps. The average value of jitter was 0.253 ms for OpenFlow switch and 0.309 ms for conventional switch. Datagram loss in OpenFlow switch value was 0.10% and in conventional switch was 0.40%.It can be concluded that OpenFlow switch have better performance than the conventional switch.

Judul: Uji Kinerja Layanan Video dalam Local Area Network (LAN) berbasis OpenFlow.
Abstrak: Software defined network (SDN) OpenFlow merupakan teknologi baru pada jaringan komputer, khususnya teknologi switching. OpenFlow menyediakan protokol untuk mengontrol bagaimana paket diteruskan melalui sebuah jaringan dan dapat diprogram secara terpusat. Tujuan penelitian ini adalah melakukan ujicoba kinerja pada jaringan lokal berbasis Openflow yang menyediakan layanan video. Metode yang digunakan dalam penelitian ini adalah menghitung dan menganalisis nilai-nilai kualitas layanan quality of service (QoS) yaitu delay, jitter, packet loss dan throughput. Untuk parameter video yang akan diakses yaitu resolution, bitrate dan frame per second (fps). Pengujian dilakukan dengan host mengakses video melalui jaringan berbasis OpenFlow. Hasil penelitian menujukkan nilai maksimum throughput yang didapatkan sebesar 667 Kbps pada pengujian dengan atribut resolution 480p (pixel). Nilai delay maksimum didapat sebesar 14.726 ms pada pengujian dengan atribut resolution 720p (pixel). Nilai maksimum dari packet loss sebesar 1.36 % didapat dari pengujian pada atribut video bitrate 1028 Kbps dengan 29.97 fps. Semakin besar nilai pada parameter video maka semakin besar nilai QoS pada jaringan. Berdasarkan hasil penelitian semua nilai QoS pada jaringan OpenFlow dengan nilai delay, jitter, packet loss dan throughput masuk dalam kategori excellent (Sangat Baik).

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
