The smartphone market is now more and more, not only in the conventional penjualanya but have penetrated in the online shop. But not all smartphones have good quality to support the needs of consumers and it is to be noticed by the consumer. Before consumers decide to buy android smartphone or belackberry consumer should know the details of the specifications and functions of the smartphone, it can be learned from the testimony and opinion or the results of a user review comments or belackberry difference android smartphone. Reading the comments of the review as a whole can be time consuming, but if only a few comments are read reviews on evaluations will be biased. Of some of the techniques most often used for data classification is Support Vector Machines (SVM). SVM has the advantage of being able to identify the separate hyperplane that maximizes the margin between two different classes. Selection of features at once setup parameters in SVM significantly influence the results of classification accuracy. Therefore, in this study used the incorporation of feature selection methods, namely Genetic Encryption (GA) in order to improve the accuracy of the classifier Support Vector Machines.

Abstract

Masalah kemanan komputer merupakan faktor yang sangat penting untuk diperhatikan dan dikelola dengan baik oleh sistem administrator. Di era teknologi informasi saat ini, layanan kepada konsumen menjadi hal yang mutlak untuk bisa bertahan dalam persaingan usaha. Banyak sekali cara yang ditempuh untuk menghalangi seseorang/perusahaan untuk dapat memberikan layanan yang optimal. Hal ini sangat mungkin bila layanan yang diberikan melalui koneksi internet yang dapat dikatakan kurang aman. Beberapa serangan terhadap server sebagai penyedia layanan kerap dilakukan oleh hacker, walaupun tidak semua tujuan yang dilakukan berlandaskan pada bisnis atau politik belaka. Namun beberapa diantaranya juga merupakan sebagai aksi unjuk gigi guna memperoleh prestise tertentu di sebuah komunitas atau perkumpulan. Serangan DOS (Denial Of Service) dan DDOS (Distributed Denial Of Service) adalah serangan yang bisa sering kita jumpai diantara serangan - serangan lainnya. DOS dan DDOS sendiri pada dasarnya adalah sama, namun DDOS adalah serangan yang lebih terstruktur. DDOS dengan mekanisme yang pada dasarnya sama dengan DOS namun memiliki dampak yang umumnya jauh lebih besar dibandingkan dengan DOS. Mekanisme serangan DOS maupun DDOS dan cara penanggulangannya sangat penting untuk diketahui dan dipelajari bagi sistem administrator mengingat serangan ini dapat menggagu kinerja server. Dampak serangan DDOS akan menyebabkan bandwidth yang digunakan oleh korban akan habis yang mengakibatkan terputusnya koneksi antar server, Bila serangan DDOS tidak segera ditanggulangi dapat menyebabkan kerusakan secara permanen terhadap hardware dan software korban.

Abstract

Teknologi komunikasi broadband semakin banyak diminati karena kemampuan, kecepatan dan kapasitas besar yangditawarkan, dimana teknologinya tidak lepas dari penggunaan sinyal frekuensi tinggi. Sinyal pada frekuensi tinggi tersebut menimbulkan radiasi medan elektromagnetik ke lingkungan sekitarnya, termasuk tubuh manusia. Pengaruh tersebut diantaranya menimbulkan berbagai penyakit seperti penyakit ayan, migren, penyakit telinga, mata bahkan penyakit kanker [11, 12]. Penelitian ini dilakukan untuk mengobservasi pengaruh radiasi medan elektromagnetik kabel broadband terhadap manusia berdasarkan standar IEEE C95.1 tahun 1999. Penelitian dilakukan dengan mengukur radiasi kabel broadband yang diwakili oleh kabel ADSL pada layanan internet Speedy kapasitas 1 Mbps dengan menggunakan alat ukur absorbsing clamp yang terintegrasi pada conducted emission test system. Nilai radiasi yang ditimbulkan, masih dalam batas aman atau tidak, diukur menggunakan parameter power density, dimana nilai tersebut dapat diperoleh dengan mengukur daya yang diterima oleh sistem yang selanjutnya dibandingkan antara hasil pengukuran dengan standar IEEE C.95.1. Hasil dari pengukuran diperoleh bahwa nilai radiasi terbesar terjadi pada frekuensi 141,262 MHz dengan nilai (-97,87±0,33) dBmW/ . Nilai radiasi tersebut masih jauh lebih kecil dibawah syarat standar IEEE C95.1, yaitu (0 00) dBmW/ . Sehingga, dapat disimpulkan bahwa keberadaan radiasi yang dihasilkan oleh kabel broadband masih berada dalam batas aman jika radiasi ini terserap oleh tubuh.

Abstract

The presence of street vendors has now become part of the life of the urban community. Behind the existence of street vendors, there are more problems than just mastery of physical space. PKL relationships with other actors and networking among informal economy. The purpose of this research  is to reveal the meta-space as a representation of habitus and interwoven strategies and tactics of the actors in an effort to perpetuate the existence of street vendors. Field findings show, vendors supported by the presence of other actors in the informal economy networks. They also formed small groups as a tangle of strategy-tactics so that they get a bargaining position to negotiate with preman. Shape in response to changing social conditions is an attempt to defend themselves and maintain PKL existence.
