"Summary: Although there are human geographers who have previously written on matters of media and communication, and those in media and communication studies who have previously written on geographical issues, this is the first book-length dialogue in which experienced theorists and researchers from these different fields address each other directly and engage in conversation across traditional academic boundaries. The result is a compelling discussion, with the authors setting out statements of their positions before responding to the arguments made by others. One significant aspect of this discussion is a spirited debate about the sort of interdisciplinary area that might emerge as a focus for future work. Does the already-established idea of communication geography offer the best way forward? If so, what would applied or critical forms of communication geography be concerned to do? Could communication geography benefit from the sorts of conjunctural analysis that have been developed in contemporary cultural studies? Might a further way forward be to imagine an interdisciplinary field of everyday-life studies, which would draw critically on non-representational theories of practice and movement?"

"ABSTRAKPenyediaan biaya investasi yang tinggi untuk memenuhi jaringan komunikasi nirkabel yang handal dengan kapasitas yang besar merupakan salah satu tantangan bagi operator telekomunikasi saat ini. Pemanfaatan alokasi bandwith frekuensi secara efisien dan optimal merupakan salah satu solusi untuk mengatasi biaya investasi yang tinggi. Tujuan dari penelitian yang dilakukan yaitu melakukan kajian analisa kelayakan biaya CAPEX dan OPEX skema Refarming Frekuensi dengan metode Replacement Analysis (RA) sesuai dengan tingkat presentase pertumbuhan pelanggan nirkabel layanan voice dan data (2012-2017) pada salah satu operator telekomunikasi di Indonesia. Metode kajian penelitian adalah melakukan kajian analisa kelayakan metode replacement Analysis (RA) untuk mengoptimasi kapasitas jaringan skema re-farming frekuensi dengan menggunakan empat skenario implementasi, yaitu 2G/3G collocation, 2G/3G/LTE collocation, 3G/LTE collocation, dan LTE (JBS). Kesimpulan dari penelitian yang dilakukan yaitu setelah dilakukan kajian analisa kelayakan menggunakan metode Replacement Analysis (RA), skema Refarming Frekuensi merupakan salah satu solusi bagi operator telekomunikasi di Indonesia dalam melakukan optimasi kapasitas jaringan nirkabel eksisting (2G dan 3G) dan jaringan baru (LTE) yang handal dan dapat direkomendasikan sknario implementasi LTE karena biaya CAPEX dan OPEX yang dikeluarkan lebih kecil dibandingkan dengan tiga scenario implementasi yang lainnya (2G/3G collocation, 2G/3G/LTE collocation, dan 3G/LTE collocation)."

"Perkembangan pesat di bidang teknologi komunikasi saat ini memberikan kemudahan dalam menyimpan maupun mengirimkan informasi digital dengan cepat. Telah banyak metode enkripsi untuk citra digital yang telah diajukan, umumnya menggunakan skema difusi, transposisi, dan difusi-transposisi. Akan tetapi, kesulitan utama dari metode-metode tersebut adalah cara bagaimana mengacak informasi yang terdapat pada citra digital tersebut. Pada tahun 2009, Yong et al. mengajukan algoritma enkripsi dengan skema difusi-transposisi berbasis chaos dengan menggunakan parameter kontrol dimana metode ini membutuhkan waktu komputasi yang lebih cepat tanpa mengorbankan tingkat keamanannya. Pada tugas akhir ini, akan dibahas mengenai pengamanan citra digital menggunakan skema difusi-transposisi berbasis chaos, dengan fungsi chaos yang digunakan adalah logistic map pada tahap difusi dan Arnold’s cat map pada tahap tranposisi. Ruang kunci dari algoritma ini mencapai 1.84×1049 dengan sensitivitas kunci hingga 10−16 yang menjadikannya sulit untuk dipecahkan dengan bruteforce attack. Berdasarkan pengujian dengan menggunakan uji dari National Institute of Standards and Tehcnologies (NIST) keystream yang dihasilkan telah terbukti acak dan distribusi dari nilai intensitas pixel-pixel dari citra yang terenkripsi adalah uniform menjadikannya sulit untuk pecahkan dengan known plaintext attack.

Rapid improvement in technology and communication provides ease in either saving or sending digital information. A number of encryption method on digital images has been proposed in recent years, commonly using diffusion, permutation, and diffusion-permutation scheme. However, the main obstacle in designing encryption algorithm is rather difficult to swiftly shuffle and diffuse the information on digital image. In 2009, Yong et al. proposed a chaos-based encryption algorithm using diffusion-permutation scheme using control parameters which posseses fast encryption speed and high security.

On this skripsi, digital image will be secured by using chaos-based encryption with diffusion-transposition scheme, chaotic function will be employed to generate random number on diffusion is logistic map and Arnold’s cat map on transposition. Key space of this algorithm is 1.84×1049 with sensitivity up to 10−16 will provides high resistance from bruteforce attack. Based on National Institute of Standards and Technologies (NIST) test, keystream produced has shown to be random, moreover histogram of pixel value from the chipertext is almost flat which means the distribution of the pixel value is uniform that would provides high resistance from known plaintext attack."

"ABSTRAKPerkembangan komunikasi dan teknologi membuat adanya beragam strategi baru dalam bermanajemen persona online. Facebook merupakan salah satu media sosial yang membuat batasan antara persona publik dan privat menjadi kabur. Penelitian ini ingin mengeksplor praktik pseudonim yang dilakukan oleh fans budaya populer Jepang dalam Facebook dalam memisahkan akun untuk identitasnya sebagai fans dan sebagai non-fans. Penelitian ini menggunakan jenis penelitian kualitatif dengan analisis fenomenologi interpretif. Hasil penelitian menemukan bahwa motivasi utama partisipan untuk memisahkan akun adalah untuk menghindari ancaman stereotip dari masyarakat. Penelitian ini juga menemukan adanya bentuk strategi manajemen persona baru yang memanfaatkan fitur-fitur teknologi dalam sosial media seperti memblokir teman, memberhentikan pertemanan (unfriend), mengatur privasi, dan strategi-strategi lainnya sehingga meskipun persona mereka berada dalam ranah publik, persona mereka akan tetap berada dalam level privat kepada audiens tertentu

ABSTRAKThe development of communication technology makes a new form of persona management strategies. Facebook is one of social media which can make the borders of public persona and private persona to be blurred and invisible. This research aims to explore the persona management in pseudonym practice by Japanese popular culture?s fan on Facebook by separating their personas in RL (real life) account and fannish account. This research is a qualitative research and using an interpretative phenomenological approach. Study found that the main motive of fans using pseudonimity in social media is to avoid the stereotype threats from their real life society. Study also found that there?s a new form of persona management strategies by using social media?s technology features such as blocking, unfriend-ing, and using privacy setting feature, and the other strategies. So, their persona is public yet private towards some audience."
