Abstract

User Experience (UX) is an important aspect in the development of digital business as it is one of the key in website content. Researchers have attributed a pleasurable user experience to the fulfillment of the following variables: usability, satisfaction, enjoyment, fun and visual appeal. Parallax scrolling as one of the web design techniques is considered to bring UX to a new interactive level and is even considered a new limitation in UX. Therefore, parallax scrolling has recently become quite popular among web developers. Parallax scrolling is a visual effect that duplicates the depth of an image or two-dimensional screen to make it look three dimensional. Unfortunately, speculation about parallax scrolling and UX relationships is still emerging because parallax scrolling is considered bad for search engine optimization (SEO), weakening internal linking and causing load duration due to the large number of images used in websites with parallax scrolling which may then potentially have an effect on UX. In this study used the above variables in order to see how the user experience when interacting with the website with and without parallax scrolling and find the reason why parallax scrolling is considered to have an effect or no effect on UX.The results showed that participants' experience did not differ greatly, so parallax scrolling concluded did not significantly affect UX. Another reason why parallax scrolling is considered to be unaffected is that in the study only two participants were aware of the effects of parallax scrolling on the website they were using, so it was not certain that the assessment by all participants was due to the use of parallax scrolling.

Abstract

IoT middleware telah dikembangkan untuk mengatasi masalah syntactical interoperability dengan menggunakan gateway multiprotokol yaitu MQTT, CoAP, dan Websocket. Dengan beragamnya perangkat yang dapat digunakan sebagai host untuk middleware timbul pertanyaan bagaimana spesifikasi minimal untuk perangkat yang dapat digunakan sebagai host untuk middleware sehingga pada penelitian ini host yang digunakan untuk middleware adalah raspberry pi zero dengan mempertimbangkan karakteristik raspberry pi zero yang lebih sederhana untuk mengetahui bagaimana kinerja dari IoT middleware jika dihadapkan pada perangkat yang lebih sederhana dan untuk mengetahui batasan bawah kebutuhan perangkat untuk IoT middleware ini. Hasil dari pengujian menunjukkan bahwa rata-rata penggunaan CPU oleh middleware sebesar 1,25% dan penggunaan memori sekitar 13%. Delay yang dibutuhkan dari publisher hingga sampai ke aplikasi sebesar 0,868 detik untuk protokol MQTT dan 0,962 detik untuk protokol CoAP. Dari segi skalabilitas, middleware mampu menangani hingga 81 pesan per detik untuk protokol MQTT, 41 pesan per detik untuk protokol CoAP dengan jumlah publisher sebanyak 100. Sedangkan pada protokol Websocket jumlah subscriber yang dapat ditangani meningkat seiring dengan bertambahnya jumlah klien hingga mencapai 54 pesan per detik. Secara keseluruhan dapat disimpulkan bahwa kinerja dari middleware pada raspberry pi 2 lebih baik daripada kinerja middleware pada raspberry pi zero.

Abstract

Requirement engineering is the initial stages of software engineering activities, where requirements elicited and analyzed. Requirement prioritization is an important process in requirement engineering that can determine the success of a software development project. Requirement prioritization activities can choose which requirements are important and less important, so the resource of the development team can focus on solving the key problem first so that resources are not wasted to solve a less urgent problem. MVGB (Majority Voting Goal Based) is a requirements prioritization method that takes into account the value given by each stakeholder as well as the dependency value of a requirement. This system of prioritizing software requirements using MVGB method is a system that provides a place to elicit and prioritize requirements by involving selected stakeholders using web technologies. The system has 46 functional requirements that are useful for elicitation, observation, and prioritization of requirements, the system has been tested with unit testing for 3 major system functions, integration testing for 3 pairs of system main classes, and validation testing for all requirements, the test yield a valid value for all test cases.

Abstract

Transmission control protocol (TCP) is a protocol at the transport layer that provides a reliable data transfer mechanism, so that the data stream reads TCP receiver is not corrupted, without duplication, and sequentially. To provide reliable data transfer, TCP provides error checking and flow control services. When the TCP sender sends data faster than the TCP receiver can handle, congestion will occur. TCP implements a congestion control mechanism for network traffic control so no congestion occurs. This study compares the performance of four variants of TCP congestion control, namely TCP Cubic, Reno, Vegas and Westwood +. The test is to analyze cwnd, ssthresh and throughput of four types of TCP Congestion Control algorithm. The author uses two devices as a sender and receiver. Both are connected with an ethernet cable that has a connection with 100Mbit/s bandwidth. TCP data is collected on the sender side using TCP Probe and the result is shown as a graph with Gnuplot. The results of this study indicate that TCP Westwood + is the best among the three other TCPs in all Service Center agreement (SLA) service provider environments with Bandwidth Estimation mechanisms they use.

Abstract

BitTorrent is a file sharing application that uses a peer-to-peer mechanism to distribute pieces of files (chunk). The process of determining the seeder is still done randomly, so to get the optimal seeder needs to be optimistic unchoking. In this study BitTorrent is implemented with software a defined-network concept that separates the control plane and data plane to facilitate application development. The reactive routing controller creates a flow table that use to connect between the peers and determines the peer list as the nearest seeder based on the number of hop using the Dijkstra algorithm. The simulation results show that the system can select some of the nearest seeders by reactive routing based on the number of hops traversed. we use BitTornado for application BitTorrent client and use Pybtracker for application of tracker. Here we observe download rate and throughput generated on BitTorrent application with random seeder and BitTorrent application that has been modified with controller. The test results obtained an average value of download rate 4785.3 Kbps with 25 seconds distribution time on 3 random seeders, 6378.3 Kbps with a distribution time of 17 seconds on 5 random seeders, 6721.9 Kbps with 18 seconds distribution time on 7 random seeders and 5990.8 Kbps with time distribution of 18 seconds on 3 seeders, 6732.1 Kbps with 15 seconds distribution time on 5 seeders, 7656.53 Kbps with 15 seconds distribution time on 7 seeders.
