Electronic Traffic Law Enforcement (ETLE) is a way of using information technology to record a violation of traffic. This ETLE was developed to support security, order, and safety in traffic. Some cities or districts in Indonesia have started to apply this ETLE in several locations, which usually have traffic lights and frequent violations at these locations. In this paper, one of the elements in ETLE is tested, which is a traffic light signal detector, which will be used as a basis for whether a vehicle violates a traffic light or not. This detector uses a CCTV camera mounted on the location.

Using the basic principle of polarization of light using a Polaroid filter or polarizer, the designing of a light intensity control was done. The polarizing angle of the filter decides the intensity of the light that would pass through the filters. According to the principle of propagation of light, the electric and magnetic vibrations of a light wave occur perpendicularly to each other. A light wave that is vibrating in more than one plan

Abstract:

In many regions, outdoor lighting systems operate at fixed intensities, regardless of the current weather conditions, resulting in energy wastage and reduced lighting efficiency. During foggy, cloudy, or rainy weather, the fixed lighting may not provide adequate illumination, compromising visibility and safety. Conversely, during clear weather or dawn/dusk periods, the lighting may be unnecessarily bright, leading to excessive energy consumption. There is a need for an intelligent, weather-adaptive light intensity controller that dynamically adjusts the brightness of outdoor lighting systems b

Abstract:

It is already known that light quality and intensity have major influences on the growth, etiolation, germination, and morphology of many plant species, but there is limited information about the effect of wavelength and light intensity on nutrient absorption by plants. Therefore, this study was established to evaluate the plant growth, stomata formation, chlorophyll index, and absorption of macro- and micronutrients by common bean plants under six light treatments. The experimental design was completely randomized and consisted of six treatments: strong blue (blue LED at high light intensity)

Abstract:

In order to study the main ways of light pollution and factors affecting light pollution, this paper first determines light pollution from the main source, namely lighting pollution, and lighting mainly refers to the light emitted by LED lamps. Therefore we come to study the light intensity of LED lamps to study light pollution. Secondly, we simplified the spectrum of LED lights into three chromatograms of red, yellow and blue, and we gradually reduced the proportion of blue light in our study to observe the intensity changes of the chromatograms. Next, we investigated the relationship between

Abstract Objective: To compare the microleakage of the enamel-adhesive-bracket complex at the occlusal and gingival margins of brackets bonded with high-intensity light curing lights and conventional halogen lights. Materials and Methods: Forty-five freshly extracted human maxillary premolar teeth were randomly separated into three groups of 15 teeth each. Stainless steel brackets were bonded in all groups according to the manufacturer's recommendations. Specimens (15 per group) were cured for 40 seconds with a conventional halogen light, 20 seconds with light-emitting diode (LED), and 6 secon

Abstract:

The main objective of this project is to develop an embedded system which switches or turn ON the light by detecting the vehicles on the road for energy saving of street light.Whenever IR sensor is detected it just indicates the Arduino to switch on the street lights. Then lights are switched on till the vehicle leaves and switches off automatically.Another way to this approach is, one can maintain minimum intensity without completely switching off the lights by using PWM and switch them on to maximum intensity whenever it detects the vehicle. But in this article the circuit is designed in suc

Abstract Light Emitting Diode (LED) lamps are a type of lamp that can be used as a light source for plants. The colour of the light that is suitable for plant growth needs to be determined precisely to obtain optimal growth and productivity of Pak Choi (Brassica rapa L.). This research aims to obtain the best light intensity and duration of exposure to white LED grow lights for the growth and productivity of Pak Choi plants using rock wool as a growing medium. This research was conducted using experimental methods and a factorial completely randomised design (CRD). The first factor is the trea
