Videotron is installed on the side of the road to attract motorists and pedestrians to view advertisements. Besides being used as an advertising, videotron is also used by local governments as information medium for the public. But, the light effect of the videotron if excessive and also the sudden change in light, greatly affects motorized vehicle users and pedestrians. The existence of this glare effect needs special attention, for that the PKM team partnered with the Indonesian Illuminating Engineering Society (HTII), to measure videotron lighting. HTII is a professional association engaged in lighting, which also pays attention to videotron lighting, especially the glare effects caused by videotron lighting, which if excessive will interfere with the visual comfort and safety of road users, especially motorized vehicle users. The measurement method is field measurements using a luminance meter measuring instrument, namely by measuring the luminance value of the videotrone lighting. Measurements were carried out along Thamrin road, especially in the Indonesian hotel roundabout area. The purpose of the measurement is not only to determine the luminance value of the videotron, but also for the DKI Jakarta Regional Government and other regional governments as the videotron management party, in making rules for videotron. The results of this PKM are videotron measurement data, namely the luminance and illuminance values, in the form of tables or graphs, for easier further analysis.

Professional associations that aim to become a forum for the professional community should have several alternative information media as an extension of the organization's arm for professionals and the public. Some of the information media that are currently widely used are web pages, Instagram, and YouTube. The Indonesian Illuminating Engineering Society (HTII) is one of the professional associations whose existence has been sufficiently recognized in Indonesia. Established on 7 May 1991 in Jakarta, until now it is still very active in various activities in the field of illumination. The development of HTII is not followed by the presence of information media that ca...

The Cileunyi-Sumedang-Dawuan Toll Tunnel (Cisumdawu Tunnel) is part of the Cisumdawu toll road, which is in located in Cilengser Village. The Cisumdawu Tunnel is currently under construction, as well as the installation of its lighting, both for night and day lighting. Tunnel lighting at night has a light intensity that is equivalent to the surrounding street lighting, but during the day you must consider the presence of sunlight which has a very high light intensity. For this reason, during the day what needs to be paid attention to is the front of the tunnel, which is the part when the driver starts to enter the tunnel. Due to the surrounding toll road, which is still under construction, the Cisumdawu tunnel is not yet accessible to the public. For this reason, on this occasion it was used for the implementation of PKM, in the form of data collection of day and night lig...

A sound level meter needs to be calibrated to determine the accuracy. The purpose of calibrating the sound level meter is to solve the problem of inequality of measurement results when measuring using the instrument. Calibration of the sound level is focused on the calibration of the Band Pass Filter with a frequency range of 63 Hz - 8000 Hz with several measuring points, namely 63 Hz, 125 Hz, 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, 4000 Hz and 8000 Hz based on ISO / IEC 61672-3: 2017. In this research, a tool to calibrate the sound level meter is designed which can work automatically without moving the measuring point selector. This tool uses a processing module, a Wi-Fi module, a dashboard on a laptop and a Band Pass Filter module. The overall system test results show the accuracy level of BPF module output frequencies above 99%, the measuring point 125 Hz - 8000 Hz which is in ac...
