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: Perancangan Dan Implementasi Jaringan Wifi Berbasiskan Protokol Openflow
Abstrak: OpenFlow merupakan teknologi baru pada jaringan komputer, khususnya pada teknologi switching. OpenFlow menyediakan protokol yang mengizinkan controller untuk meneruskan paket melalui sebuah jaringan dan dapat diprogram secara terpusat. Tujuan penelitian ini adalah merancang dan menerapkan jaringan WiFi menggunakan protokol OpenFlow. Metode penelitian ini terdiri atas beberapa proses yaitu analisis masalah, perancangan jaringan OpenFlow, implementasi protokol OpenFlow menggunakan jaringan WiFi, pengujian, dan analisis quality of service (QoS). Dalam melakukan analisis QoS digunakan beberapa parameter, yaitu ping test, delay, jitter, throughput, dan packet loss. Hasil penelitian menunjukkan semakin besar ukuran paket, maka semakin lama waktu delay paket pada pengujian ping test. Nilai maksimum throughput yang didapat sebesar 58.16 Mbps pada pengujian nilai bandwidth 10-60 Mbps. Nilai jitter maksimum yang didapat sebesar 0.482 ms. Nilai delay maksimum yang didapat sebesar 0.1 ms dan nilai packet loss yang didapat sebesar 0.1548%. Berdasarkan hasil penelitian tersebut, dapat disimpulkan penggunaan jaringan WiFi berbasiskan protokol OpenFlow memiliki QoS yang 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.
