Judul: Analisis kinerja video streaming pada jaringan IEEE 802.11b berbasis Ad-Hoc
Abstrak: This research presents empirical measurements of wireless media streaming traffic in an IEEE 802.11b wireless ad hoc network. The videos used were in MPEG-4 H.264 format with bit rates of 400 Kbps, 512 Kbps, and 1024 Kbps. The scenario of this experiment is that the first client access video streaming from the server and the second client until the tenth client will access the video streaming with 27 seconds between each clients. The parameters to be analyzed were the average delay, average packet RTP, and average packet loss. The results show that the IEEE 802.11b WLAN with video bit rate of 400 Kbps can support up to 8 clients with good media streaming quality. With 9 clients, the WLAN is overloaded, and performance degrades for all clients. Video bit rate of 512 Kbps can support up to 4 clients with good media streaming quality, and video bit rate 1024 Kbps does not meet any client with good media streaming quality based on Quality of Service (QoS).

Judul: Analisis Pengaruh Kecepatan Mobilitas Terhadap Kinerja Video Streaming pada Jaringan Wireless Ad Hoc
Abstrak: Wireless technology has become a lifestyle in many countries. Though wireless networks provide more flexibility than wired networks, it has lower reliability and data transfer speed than wired networks. The development of streaming technology is analogous with the quality of the streaming services. Streaming technology becomes increasingly important with the growth of the internet because most users do not have fast enough connection to download large multimedia files quickly. This research presents calculations of data from experiments of video streaming performances in wireless ad hoc networks with bit rate format of video 256 Kbps, 512 Kbps, and 768 Kbps. Data captured from the experiments is divided into four scenarios: client performs mobility and client does not perform mobility, with one client perform video streaming and two clients perform video streaming concurrently. Client’s mobility speed is limited only by walking speed, which are 0.6 m/s, 1.2 m/s and 1.6 m/s. The video quality calculations are based on the Quality of Service (QoS) of video streaming, which include packet loss, throughput, delta and jitter.

Judul: Karakteristik Anatomi Skelet Kepala Buaya senyulong (Tomistoma schlegelii).
Abstrak: Buaya sepit atau senyulong (Tomistoma schlegelii) merupakan jenis buaya asli Indonesia yang berhabitat di sungai-sungai Sumatera, Kalimantan, dan juga pedalaman Sulawesi. Salah satu ciri khas buaya senyulong adalah bentuk moncong yang runcing dan sempit, namun hingga saat ini informasi mengenai struktur skelet kepala buaya senyulong sangat terbatas. Penelitian ini bertujuan untuk mempelajari karakteristik anatomi skelet kepala buaya senyulong yang dikatikan dengan fungsi dan perilakunya. Penelitian dilakukan secara eksploratif dengan melakukan pengamatan, pencatatan, dan pengambilan gambar dari skelet kepala buaya senyulong. Skelet kepala berukuran panjang 70 cm, lebar 29 cm, dan tingggi 17 cm dengan permukaan kasar pada os nasale, os frontale, os maxilla, os mandibula, os lacrimale, os jugale. Jumlah gigi pada buaya ini sebanyak 78 buah, terdiri dari 4 buah gigi premaxila, 16 buah gigi maxila, dan 19 buah gigi mandibula. Pada regio orbitalis ditemukan dua pasang fenestrae temporales yang berkembang baik. Fenestra supratemporale merupakan lubang oval yang membentang di sepanjang os parietale. Fenestra infratemporale berbentuk segitiga dan dibatasi oleh os squamosum, os postorbitale, os jugulare, dan os quadratum. Os mandibula hewan ini mempunyai symphysis mandibularis yang panjang yaitu garis yang melintang di corpus mandibulae. Secara fungsional ukuran symphysis mandibularis berkaitan dengan adaptasi hewan terhadap diet makan.
