Proof of Tunnel Signature (PoTS) is designed to avoid the main problems found in certificates based on Blockchain technology. In this case, it is so closely related to Cybersecurity. A lightweight protocol such as a Certificate Authenticated Key Agreement (CAKA) is needed to reduce the vulnerability of a system's operation, namely overcoming management overhead by using a decentralized system according to the characteristics of Blockchain Technology. PoTS is the second stage after determining the Key Agreement (KA) or certificate hash in authenticating a node, and this is also a significant step in minimizing computation costs. The nodes generated after the signing process remain anonymous and can be verified optimally. Smart contracts are also used as a support so that this research can ensure transparency and openness of transaction nodes to maintain and improve the efficiency of transaction security for a certificate based on Blockchain Technology.

With the development of mobile technology is not only used as a telephone and sms only, but also can be used as a device to control a robot, as well as Android smartphones are already embedded computer features. Robot technology so can be controlled remotely and the desired user. Robot technology is also one that is able to assist the work of humans, such as the draining of human work, as well as having a high risk. Robot function which was made to minimize the risk associated with large heavy physical tasks, positioning an object, and to move goods from one place to another. Therefore designed a robot movers using a servo motor output arm movement, microcontroller as the brain, Bluetooth as a communication medium to send a data or input from the Android application that acts as a device for controlling a robot remotely.

Proses pembuatan kartu ujian setiap pergantian semester adalah mengkombinasikan beberapa komponen yang terdiri atas mahasiswa, dosen, ruangan, waktu dan pembayaran. Pembuatan kartu ujian membutuhkan waktu, tenaga dan ketelitian dalam membuatnya dan juga proses yang sangat lama yaitu sekitar satu mingguan karena masih bersifat manual alias jadul , untuk dapat menghasilkan kartu ujian pihak dari RPU harus membuat jadwal ujian dulu yang datanya diambil dari data OJRS+ . Penelitian ini membuat perancangan kartu ujian online menggunakan YII Framework. Hal ini dapat menjadi permasalahan karena masih dimungkinkan adanya resiko permasalahan bentrok. Semua permasalahan ini dapat diselesaikan dengan sebuah sistem yang dapat membuat jadwal secara otomatis atau secara online.Dengan ini akan membicarakan bagaimana membangun sebuah aplikasi penjadwalan otomatis mulai dari analisa kebutuhan hingga bagaimana sebuah permasalah penjadwalan dapat diselesaikan. Kata Kunci: Optimalisasi, online, Kartu Ujian, framework bootstrap

In an era of modernization as this is now very much in the development of applications that make use of the computer program. One of them, namely the creation of the budget costs using e-budgeting application. What is the e-budgeting? E-Budgeting is a financial system that is stored online with the aim of transparency for each party. This system is applied as documentation for the preparation of the budget is usually in an area. Anyone can access data budget compiled by a local government so hopefully can prevent attempts of embezzlement of funds. The application of e-budgeting was chosen because it can bring cost transparency can be seen by anyone who is shown through the website. The results presented in this study is the use of proven e-budgeting nature of transparency compared with the way that still are conventional. Keywords: The cost of the e-budget, budgeting, budget transparency.

Talk about retail business can not be separated from the importance of service to consumers and good quality goods . But at the present time due to intense competition in the business world , the service and quality of goods is not enough to be able to increase revenue and attract customers loyal . This makes companies think hard to survive and stable in the business . One of them is by using a media campaign in this regard more toward print or visual media is indirectly felt the value of their effectiveness in communicating product marketing programs . PT . Times Prima Indonesia is a company engaged in the retail book with the name of the Times bookstores . Based on the analysis of the company’s problems requires additional media types supporting more varied and creatif promotion of existing ones, which will be used as a complement and a media campaign as well as to enrich the data renewal campaign design to capture the interest of consumers in which one form of the media campaign is shaped merchandise . Therefore , do Enriching ( enrich ) media campaign merchandise before it is less varied and has not formed a company image . The methodology used is the analysis, observation and design . Besides the new design has been tested with the implemented test duration for 6 months, and greatly increases the perceived contribution , this is evidenced by the chart sales increasing each month.
