Desain Intensitas Penerangan dengan Tipe Jenis Lampu untuk Kegitan Praktikum di Laboratorium Mesin Listrik dan Pengukuran

Lighting planning in a laboratory room is one of the factors in designing to produce good and energy efficient lighting. To carry out all activities in the room of a laboratory, sufficient lighting intensity is needed, so that it can be carried out optimally, especially with regard to practicum work carried out in the laboratory for the benefit of the learning process. In terms of quality, lighting in a room is in the form of strong lighting or illumination level. The purpose of this research is to design, identify and evaluate the recommended lighting intensity / quality with the lighting standards from the existing lamp data installed in the electrical and measurement laboratory. The results of the measurement research for the Electrical Machinery and Measurement Laboratory obtained that the average light intensity for the work point of the practicum table is 127 lux, so that the light intensity is still low according to the SNI 16 - 7062 - 2004 standard with a measuring point of even lighting distribution obtained by 137 lux. If the light intensity of a laboratory is not fulfilled, it will result in inconvenience for students in carrying out the measurement practice, especially for practicum electrical circuits by calculating the value of the ring resistor. For this reason, the intensity of lighting in the laboratory room must be designed to meet the recommended lighting standards for a laboratory, namely 300 lux, namely by adding the number of 8 points of TL Philips Lifemark 36W / 54-765 lamps,or 8 points of 25 W / 2600 lumens LED lamps, or 6 Philips CLF 55 W / 3465 lumen type light point.

IoT Implementation in Remote Measuring Laboratory VMLab Analyses

The paper presents analyses of the implementation of IoT in the patent technology of the remote measuring laboratory (VMLab). The technology allows to create a new electrical connection between different devices, where the connection diagram was not defined before. This may be done remotely around the world. To begin with, an application of this technology as a remote measuring laboratory is presented and described. Analyses of the possible application of IoT technology in the Remote Measurement Laboratory (VMLAB) with a final design are also presented. The research focuses on an efficient way to retrieve measured values synchronized over the Internet from multiple measuring devices and controllable devices, without an Ethernet or Wi-Fi interface from the manufacturer. The analyses may also be useful when implementing an additional IoT approach to existing systems.

From Characterisation to Validation: A Journey through Master’s Level Analytical Chemistry

The master’s degree in Applied Analytical Chemistry at University College London (UCL) includes valuable teaching input from the UK National Measurement Laboratory for Chemical and Bio-Measurement hosted at LGC. The course starts by introducing accuracy, sensitivity, specificity, trueness, and precision for validating analytical chemistry measurement methods. The principles of proficiency tests, quality control, ruggedness, and associated statistics are practiced using a wide variety of case studies.
