Judul: Inventarisasi dan identifikasi caplak pada ular sanca kembang (Python reticulatus) dan ular sanca albino (P. bivittatus albino) di Taman Margasatwa Ragunan, Jakarta
Abstrak: Caplak merupakan salah satu ektoparasit yang menginfestasi ular. Data mengenai caplak yang menginfestasi ular sanca kembang (P. reticulatus) dan ular sanca albino (P. bivittatus albino) di Taman Margasatwa Ragunan belum ada. Penelitian ini bertujuan menginventarisasi dan mengidentifikasi caplak pada ular sanca kembang dan ular sanca albino di Taman Margasatwa Ragunan, Jakarta. Caplak dikoleksi dari bagian kepala, badan ventral, badan dorsal dan ekor. Preparat sediaan utuh caplak dibuat dengan media entellan dan media Hoyers. Prevalensi ular sanca kembang (P. reticulatus) dan sanca albino (P. bivittatus albino) diinfestasi caplak sebesar 100%. Sebanyak 1 097 ekor caplak berhasil dikoleksi pada penelitian ini. Berdasarkan karakter morfologi, seluruh caplak yang dikoleksi adalah Genus Amblyomma (Subgenus Aponomma) Spesies Amblyomma gervaisii L.. Karakteristik caplak A. gervaisii L. adalah hipostom dengan susunan gigi 3:3, skutum berornamen, koksa tungkai pertama memiliki dua spur dengan spur eksternal lebih panjang dibanding internal, basis capituli sub-triangular, sebelas lempeng festoon, dua spur pada koksa tungkai pertama dan satu spur pada koksa tungkai 2, 3, dan 4. Amblyomma gervaisii L. paling banyak ditemukan pada bagian badan ventral ular. Penelitian ini menemukan fase larva, nimfa, imago caplak jantan dan betina sedangkan fase telur dan larva jantan tidak ditemukan.

Judul: Studi Infestasi Caplak dan Deteksi Borrelia spp. pada Caplak yang Menginfestasi Kura-Kura Darat
Abstrak: Hard-bodied ticks of the genus Amblyomma that parasitize reptiles are potential vectors of zoonoses. This study aimed to describe tick infestations and detect Borrelia spp. infections in ticks found on tortoises. One hundred six tortoise hosts were examined at selected locations in Indonesia. DNA extraction and Borrelia spp. detection were carried out by conventional PCR. In this study, nineteen hard-bodied ticks were collected from one Chelonoidis carbonarius, one Chelonoidis denticulatus, and six Geochelone sulcata. All collected ticks were identified as Amblyomma sparsum. The prevalence of A. sparsum on tortoises was 7.55%. Borrelia spp. were detected in several of the A. sparsum infested on tortoises. Sequencing revealed two separate reptile-associated (REP) Borrelia strains., Caplak keras dari genus Amblyomma yang menjadi parasit pada reptil berpotensi menjadi vektor zoonosis. Penelitian ini bertujuan mendeskripsi infestasi caplak dan mendeteksi infeksi Borrelia spp. pada caplak yang ditemukan pada kura-kura darat. Seratus enam inang kura-kura darat diperiksa di beberapa tempat di Indonesia. Ekstraksi DNA dan deteksi Borrelia spp. dilakukan menggunakan metode PCR konvensional. Hasil penelitian diperoleh sembilan belas caplak keras yang dikoleksi dari seekor kura-kura darat jenis Chelonoidis carbonarius, seekor Chelonoidis denticulatus, dan enam ekor Geochelone sulcata. Jenis caplak yang ditemukan adalah Amblyomma sparsum, dengan prevalensi sebesar 7.55%. Borrelia spp. dideteksi pada beberapa A. sparsum yang menginfestasi kura-kura darat. Hasil sekuensing menunjukkan adanya dua galur reptile-associated (REP) Borrelia.

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.
