Judul: Pengembangan Model Quality of Experience untuk Televisi IPTV secara Empiris
Abstrak: Quality of Experience is closely related to expectations, customer experience and subjective perception of the performance of multimedia communications applications. Quality of Service is limited to the size of the network quality. The initial step in conducting the study is to prepare the IPTV network infrastructure consisting of a central station (headend), local transmission (core network) and a public transmission (access network). The next step is to do the Quality of Service measurement by flowing through IPTV network infrastructure a video format H.264 with a bit rate ranging from 1000 to 8000 kbps. Each node of the network is recording video packet data network (packet loss, delay and jitter). After that, map Quality of Service to Quality of Experience value using the ITU - T G1070. Transmission measurements at the central station (headend) show that the small values of QoS. Packet loss values lower than 0.10%, the value is lower than 32ms delay, and jitter values lower than 5ms. Video QoE value (VQ) ranged between 4 (Good). Stable QoE ensure good network performance. For transmission measurements on the local (core network), with a bit rate of ≥ 2000 kbps, shows that packet loss value is small (≤ 0.10%) and video QoE values ranged between 4 (Good). Average delay of RTP is approximately 60 ms and average jitter of RTP is 16.5 ms giving effect to the choppy video QoE. As for the TCP, it is relatively better because of the small value of QoS. Value of packet loss is approximately 0.0%, average delay is 5 ms and average jitter is 5.2 ms. Fluctuations QoE describe poor network performance to support IPTV services. For the measurement of the transmission to the public (access network) shows that the value of small packet loss (≤ 0.10%), the value of the RTP delay is around 60ms and jitter values of the RTP is 7.2ms. Video QoE value stable range between 4 (Good). Just as the headend, network performance has provided a good guarantee for IPTV services.

Judul: Analisis Pengaruh Spesifikasi Video Terhadap Kinerja Video Streaming pada Jaringan Mobile Interne
Abstrak: Nowadays, GSM network Infrastructure has reach the 3G or UMTS (Universal Mobile Telecommunications System) and 3.5G or HSDPA (High-Speed Downlink Packet Access), allowing the end-user streams multimedia content. The availability of network infrastructure and support does not mean that multimedia streaming is free from problem. Its main limitation is the instability of wireless network which resulted in quality degradation of the multimedia streaming. To address these problems, many of the multimedia video are made with low resolution, low frame-rate and low bit rate. This study used the latest H.264/AVC video encoding which makes multimedia streaming service possible to be performed without reducing the quality of the video. Even with the low video specification, the end-users still receive a good video display and good Quality of Service (QoS) in video streaming. There are two test case in this research which represent 2 (two) conditions of the video streaming users. The first test case simulates a situation where the user is sitting still at classroom and the second test case simulates a situation where the user walks around the campus during lunchtime. Based on the analysis of 3 (three) different criteria of QoS in video streaming, that is packet loss, delay and jitter, it was found that the performance of video streaming over the mobile internet is not only influenced by the video specification, but also the condition of the surrounding environment of the end-user. For end-users who were in classroom it is recommended to use low specification video as 320x240 pixel video resolution, frame-rate of 5 fps, and with 24, 56, or 105 kbps of bit-rate. Meanwhile, end-users who were on the outside of the class can access the video with high specifications such as video with 480x360 pixel resolution, 15 fps frame-rate, and 24, 56, or 105 kbps of bit-rate.

Judul: Karakteristik Anatomi Skelet Kepala Badak Jawa (Rhinoceros sondaicus)
Abstrak: Badak jawa (Rhinoceros sondaicus) adalah spesies badak bercula satu yang hidup di Taman Nasional Ujung Kulon (TNUK), Indonesia. Tujuan penelitian ini adalah mempelajari karakteristik anatomi skelet kepala badak jawa yang dikaitkan dengan perilakunya. Penelitian dilakukan dengan mengamati struktur dua buah skelet kepala badak jawa jantan. Skelet kepala diukur dimensi dan volume cavum cranii, dipelajari struktur dan formula giginya, didokumentasi, serta dipindai dengan CT scan. Penamaan unsur-unsur anatomi berdasarkan Nomina Anatomica Veterinaria 2015 dan kemudian struktur anatominya dibandingkan dengan pustaka pada hewan-hewan lain. Secara umum skelet kepala badak jawa memiliki pars splanchnocranii yang sangat berkembang, pars neurocranii yang meninggi ke posterior, dan atap kepala yang konkaf dan tebal disertai simus-sinus di profundal-nya. Skelet kepala badak jawa memiliki permukaan yang kasar pada os incisivum, os nasale, os frontale, dan os maxilla serta memiliki bungkul di os lacrimale dan rigi di os zygomaticum. Selain itu, hewan ini memiliki crista nuchae yang terletak di dorsoanterior condylus occipitalis dan squama occipitalis yang luas dengan persendian occipitoatlantis yang luas di sisi dorsal-nya. Arcus zygomaticus dan fossa temporalis pada hewan ini luas dan berkembang serta angulus mandibularis dan permukaan persendian rahang bawah pada os temporale yang luas. Bagian-bagian tersebut beradaptasi untuk mendukung perilaku badak jawa dalam mencari makan dan bertahan hidup….
