Abstract

Sistem monitoring mencakup pengumpulan, pelaporan, dan tindakan atas informasi suatu proses yang sedang berlangsung di suatu ruangan. Salah satu hal yang dapat dimonitoring pada ruangan adalah tingkat penggunaan listrik. Pada penelitian ini, dilakukan perancangan hardware sistem monitoring portabel yang dapat memonitoring arus dan tegangan listrik AC. Desain hardware menggunakan prosessor Raspberry Pi untuk mengolah hasil pembacaan 4 buah sensor arus YHDC tipe SCT-013-000 dan sensor tegangan AC. Hardware dapat diakses melalui antarmuka konfigurasi berbasis web yang menampilkan konektivitas jaringan dan nilai dari sensor-sensor. Hasil pengujian sensor arus pada saluran listrik 3 fase RSTN dan pengujian sensor tegangan didapatkan bahwa LCD pada hardware dan antarmuka konfigurasi berbasis web telah berhasil menampilkan nilai pembacaan sensor-sensor. Hardware juga telah berhasil terhubung ke jaringan wireless “RUANGAN01”pada alamat IP 192.168.8.107. Keseluruhan fungsionalitas antarmuka konfigurasi hardware berbasis web seperti login, koneksi perangkat, konfigurasi “on” sensor, reboot, shutdown dan reset juga telah berfungsi dengan baik dan sesuai dengan rancangan.

Abstract

Colleges in Indonesia as part of an educational institution that seeks to improve the competitiveness of globally through the utilization of ICT (information and communication technology) has been aware of the importance of the website as a key component of the assessment in an effort to align ourselves as a global standard of the College. The instruments most frequently used by universities as reference materials to evaluate performance and productivity based on his/her website is through a college assessor database world, including Webometrics and 4ICU. Correlation between linking Webometrics and 4ICU are aimed to assist colleges in analyzing the quality of traffic services in the field of scientific publications in order to be able to compete in the global sphere and certainly for the better. The methodology used by using spearman rank correlation against major # 29 University according to the webometrics ranking based on 4ICU and 29 top-rated website 4ICU. The results of the research there is a relationship or a significant correlation between the webometrics ranking indicator with indicator correlation value 4ICU ranking of 0.591 contains the category strong enough.

Abstract

Various web-based information systems are developed by Indonesian government to improve quality of services for their society. It encourages users, generally civil servants, to perform different authentications on used information systems and have to remember credentials. Account management of the users poses another challenge for administrators. Single Sign-On (SSO) can be the solution by providing a service of centralized authentication and user account management. This study applies a token-based SSO architecture and uses Json Web Token (JWT) to grant permission authorities, since JWT can provide a claim process between 2 parties. Additionally, the built-in dashboard lists associated information systems to facilitate accessing for the authenticated users. This study will discuss JWT implementation on the dashboard of government information systems that implements SSO, which will generate the permission authorities securely for connected information systems on SSO.

Abstract

In general, visual sensors are applied to build virtual view images. When number of visual sensors increases then quantity and quality of  the information improves. However, the view images generation is a challenging task in Wireless Visual Sensor Network environment due to energy restriction, computation complexity, and bandwidth limitation. Hence this paper presents a new method of virtual view images generation from selected cameras on Wireless Visual Sensor Network. The aim of the paper is to meet  bandwidth and energy limitations without reducing information quality. The experiment results showed that this method could minimize number of transmitted imageries with sufficient information..

Abstract

One of significant change in learning process is exam implementation applying a computer-based test (e-exam) rather than paper-based test. Many institutions currently use wireless network with bring your own device (BYOD) policy for their e-exam implementation, due to limitation of space and user terminals. Moreover it is hard to maintain the availability of reliable signal quality in wireless network for all users during e-exam process. Therefore, this research proposes a development of time adaptive for mobile exam (TAMEx) framework to provide all users with good quality of service of e-exam in wireless network environment when dealing with signal quality variations. The received signal strength indication (RSSI) is the main indicator of the signal quality. The framework supports e-exam implementation in wirelesslocal area network and the use of BYOD mechanism. The research shows that the framework successfully has provided time compensation for the users who experienced temporary connection loss due to bad signal quality. The result exhibits that tiny processing time has been needed for signal loss detection, user’s request of compensation time, and server’s execution. In conclusion, the TAMEx could guarantee good services for all users who doing e-exam in wireless network environment.

Abstract

The increasingly inexpensive Internet has spurred the growth of online information system services in various companies. Almost all services are available in forms on web or mobile applications. For small companies, this particular system is more difficult to implement as it requires a substantial cost allocated for hosting, domain and server devices. The solution is to develop a framework for building information system services through Instant Messaging (IM) such as Telegram, Line or XMPP / Jabber using the Design Science Research Methodology. This proposed framework has the ability to transform the existing information system services into chat services with RBAC role, session, validation and natural interaction using Indonesian-language conversations. The framework that consists of Initiate layers, business process and communication, memory group and OLTP DBMS will produce low-cost solution for the development of integrated information systems service.

Abstract

Tujuan dari pengabdian kepada masyarakat yang dilakukan di Desa Katung, Kecamatan Kintamani, Kabupaten Bangli ini adalah untuk mengimplementasikan sistem e-cerdas cermat pada lomba asah terampil yang akan dilakukan oleh Gabungan Kelompok Tani (Gapoktan) Budhi Luhur. Target khusus yang ingin dicapai dalam kegiatan pengabdian ini adalah untuk meningkatkan kualitas kegiatan asah terampil di Gapoktan Budhi luhur, yang sebelumnya masih bersifat konvensional, menjadi sebuah acara yang dikemas menarik dalam balutan teknologi informasi melalui sistem E-cerdas cermat. Awal-awal simulasi adalah kondisi yang sangat berat, karena calon peserta merasa akan kesulitan dalam menggunakan perangkat laptop/handphone dalam melaksanakan lomba. Namun setelah mulai merasa familiar para peserta merasa sangat tertarik, tertantang, dan merasa ingin lagi merasakan sensasi lomba dengan sistem E-cerdas cermat.

Abstract

In this tool utilizing the Raspberry Pi and Arduino Uno Microcontrollers as equipment that can provide a good level of security for home security with visual sensor based. This tool uses an electronic key where you can electronically open and lock the door based on the password inputted using the keypad. The whole system on the electronic key is fully controlled by the Arduino Uno Microcontroller and if the password inputted on the keypad is more than three times wrong, an buzzer will ring, the camera will take a picture and the Raspberry Pi Microcontroller will immediately send a notification to the homeowner via the Telegram application. . When someone wants to try to get into the house by using the correct or wrong password the camera will still automatically take pictures and will immediately send notifications in the form of text and images to the homeowner through the Telegram application. In conditions far from home the homeowner can also find out the current state of the house through the Telegram application. In the system this tool uses a password where passwords can be stored in the form of "hard code", the average delay in each experiment of this tool is around three minutes.
