Perancangan Sistem Autentikasi Pengguna dan Monitoring Kelistrikan CNC Router G-Weike WK1212 Berbasis Internet of Thing (IoT)

Internet of Thing (IoT) technology is able to manage devices to collect and exchange data over the internet network. IoT is one of the keys to implementing Industry 4.0 in various sectors such as manufacturing, transportation and even education. IoT can be utilized for laboratory device management. The Production Systems Laboratory, Faculty of Engineering, Dian Nuswantoro University has CNC-based machines such as a CNC router machine with the G-Eike brand type WK1212. Through the implementation of IoT, user data, operational time, and electricity such as voltage and current while the CNC machine is operating can be sent and stored on a database server. Furthermore, analysis of the data is carried out for various purposes such as predicting machine maintenance schedules. The results of the research that has been carried out regarding the design of user authentication systems and electrical monitoring of the CNC machine have been tested with good results in extracting the required data via IoT to then be used in predicting machine maintenance. It is known from the test results that the user (student) authentication system can be carried out by inputting a username and password based on student data registered by the laboratory assistant. Electrical data (voltage, current, power, energy, frequency and power factor) is successfully sent from the control panel periodically every 10 seconds to the broker. The broker managed to save the data received into the MySQL database.    Keywords: Internet of Thing, CNC Router, G-Weike WK1212, Autentikasi, Monitoring.   ABSTRAK  Teknologi Internet of Thing (IoT) mampu mengelola perangkat untuk mengumpulkan serta bertukar data melalui jaringan internet.

Laboratorium Sistem Produksi Fakultas Teknik Universitas Dian Nuswantoro memiliki mesin-mesin berbasis CNC seperti mesin CNC router dengan Merk G-Eike tipe WK1212. Melalui penerapan IoT maka data pengguna, waktu operasional, dan kelistrikan seperti tegangan dan arus selama mesin CNC beroperasi dapat dikirim dan disimpan pada server basis data. Selanjutnya, analisis terhadap data tersebut dilakukan untuk berbagai keperluan seperti memprediksikan jadwal pemeliharaan mesin. Hasil dari penelitian yang telah dilakukan terkait perancangan sistem autentikasi pengguna dan monitoring kelistrikan mesin CNC tersebut telah diuji dengan hasil yang baik dalam menarik data-data yang dibutuhkan melalui IoT untuk kemudian dapat dimanfaatkan dalam prediksi pemeliharaan mesin. Diketahui dari hasil uji tersebut sistem autentikasi pengguna (mahasiswa) mampu dilakukan melalui input username dan password berdasarkan data mahasiswa yang didaftarkan oleh asisten laboratorium. Data kelistrikan (tegangan, arus, power, energi, frekuensi dan power factor) berhasil dikirim dari kontrol panel secara periodik tiap 10 detik ke broker. Broker berhasil menyimpan data yang diterima ke dalam database MySQL

A Framework Design for Information Management in Heritage Science Laboratories

The dataflow in any scientific research laboratory is continuous and considerable even in analytical niches such as heritage science laboratories. This article discusses advantages of using a Laboratory Information Management System (LIMS) for organising and systematising research in an interdisciplinary analytical laboratory. LIMS solutions are proven to be effective in managing laboratories, organising their daily management tasks, improving work conditions and increasing productivity, managing equipment and resources, and managing and safeguarding scientific data. LIMS software is commercially available since the 1990s with over a hundred software packages intended either for general or specific purposes. However, the ones currently available do not fulfil all the requirements for heritage science or are over-the-top, complex, one-fits-all standard solutions. The system here proposed was developed for a heritage science laboratory, considering its unique requirements, having as a case study the HERCULES Lab, from the University of Évora (Portugal). This article documents our approach based on the analysis of the unique requirements for the lab resulting in a proposal of a custom user-centred web-based system. For this, we discuss in detail the workflow, and the required system architecture. We conclude that although it is a small niche market for major manufacturers to dwell on, a custom LIMS is of the utmost importance for the current management of heritage science laboratories across the globe
