Aquarium Water

Indonesia is an endemic area for the spread of one of the most popular ornamental fish, namely the largest betta fish in the world. In exploring their hobbies such as raising ornamental fish such as betta fish, efficient and automatic tools are more needed by betta fish farmers in aquariums today, when they have no free time or are drained by other work. This study aims to be a more automatic and efficient tool for everyone to feed fish, provide lighting, and drain aquarium water automatically, so that owners of ornamental fish do not have to worry about what ornamental fish need in the aquarium. The feeding system, in this case uses an Arduino-based control that controls the servo motor as an open and close system as the exit of fish feed into the aquarium. Aquarium lighting system, in this system uses a light sensor type LDR (Light Dependent Resistor). Automatic aquarium drain system, controlled by Arduino with water pump output. In the research, the LDR sensor will give a signal to the relay and give output to the 220 V lamp, that is, if the light intensity is below 028.7 Lux, which is above half past 6 pm and will turn off the 220 volt lamp if the light intensity is above 203.4 Lux, which is above 6 am. The servo motor will operate twice a day for feeding according to the betta fish feed needs, which is 2 times a day. The water pump will work every 4 days to drain the water automatically according to the turbidity of the water based on the time and number of betta fish in the aquarium.

Operation theatre lighting system is a critical component in the operation theatre. Focusing the light to the area of surgery and varying the light intensity is manually done in currently available systems. Disruption of surgeon’s attention and possibility of infection due to non sterilized hands is a major setback of the manual controlling method. This usually requires assistants to adjust the position and intensity of the light system by commands from the surgeon. So, designing an intelligent lighting system for operating theatre which can maintain the intensity values to the required level without shadow effect to the operation area is an important requirement. Proposed system makes use of accelerators in the gloves worn by surgeon so as to track hand movements. Pre defined hand movements can be configured to move the lighting system up, down, left or right. Accelerator input is interpreted for its corresponding movement by controller at transmitter side and it is wirelessly given to the receiver side using an nRF module. At the receiver side the incoming command from the nRF is taken and suitable response generated at the motor driver by the controller to move the lighting device. In the same way predefined hand signal can be used to vary the intensity of the light by using microcontroller to drive an LED driver.

Poultry producers accustomed to use light colours in broiler production as atrial to increase their productivity, especially in the developing countries to cover the animal protein gap. This experiment was planned to study the effect of different blue light colour intensities (high, medium and dim) on a recently imported Indian River (IR) broilers to Egypt. In this study, 270 one-day old Indian River broiler chicks were used. The birds were exposed to high blue light intensity (HBLI), medium blue light intensity (MBLI) and dim blue light intensity (DBLI), through a monochromatic lighting system that was installed in different rooms for 24 hours daily. The birds were randomly divided and housed into three well controlled pens of 5.46 m2 with three replicates of 30 each using a density of 17 birds/m2 in the room. The results showed that the broilers reared under DBLI had a significantly (p< 0.05) higher body weight, body weight gain, Newcastle disease virus antibody titer and foot pad dermatitis with obviously, economic Feed conversion ratio (FCR) and low activities and heterophyil/lymphocyte ratio in comparing with (MBLI) and (HBLI). In conclusion, poultry producer can use dim blue light in their farms to reduce the activities and increase the productivity of the birds.

ZigBee is a kind of low rate, low cost and low power technology to be used in cheap, fixed, portable and mobile devices in wireless sensor network. The wireless smart indoor lighting system based on ZigBee technology uses the chip CC2530 as the core. It can collect the light intensity signals of LEDs in real time; perform pulse width modulation (PWM) and wireless communications. The system can also display these parameters on a personal computer such as temperature, light intensity and so on. Even the real-time parameters may be transmitted to the mobile phone to monitor. As a result of the indoor tests that have been conducted, the smart lighting system is more humanized, safe and energy-efficient.

The research was conducted to explain how to design a simulation of Solar tracker on Wind-Solar hybrid technology. The simulation were carried out with proteus software simulation. Solar tracker has four LDR sensors and an Arduino Uno Microcontroller which assist the Solar tracker to estimating position of the sun to use a servo motor for solar cell movement. For the result, When the upper light intensity (LDR 1 and LDR 2) is greater than the bottom (LDR 3 and LDR 4), solar cell will move upwards, and vice versa. When the light intensity of the left (LDR 1 and LDR 3) is greater than the right (LDR 2 and LDR 4), solar cell will move to the left, and vice versa. From the research, it could concluded that Solar Tracker can be applied to Wind-Solar technology solar cells

While investigating traffic accidents that took place during darkness hours on unlighted area of carriage way, investigating authorities are interested in reasons that, from a technical point of view, could lead vehicle to run down a pedestrian or a stationary obstacle, to a collision of vehicles. Furthermore, while performing research on technical condition of a vehicle lighting system using modern equipment, forensic autotechnician experts are faced with problems related to the lack of skills in using such equipment. Moreover, while solving certain issues related to the technical state of lighting system, posed questions are not fully disclosed by forensic autotechnician experts, “narrow” conclusions are made, so far as during examining technical state of vehicle lighting system, most forensic autotechnician experts do not apply to State Standard DSTU 3649:2010 requirements. This article details the order of actions of specialists, forensic experts while performing research on technical state of the vehicle lighting system using the modern OMA 684D device. The minimum values of headlamp intensity for certain types of headlights bulbs in according to Rules ECE UNO (Economic Commission for Europe the United Nations Organization) requirements are described. Recommendations for use of DSTU 3649:2010 are given while performing research technical condition of vehicle lighting system. To obtain result values in candelas, as required by DSTU 3649:2010, the calculation of the translation of the values of headlamps light intensity from luxes to candelas is offered. Minimum and maximum values of the headlamps light intensity for certain types of light distribution according to DSTU 3649:2010 are also indicated. The decoding of headlight types with values of light intensity is given. For better perception of the correctness of the research results, images of the control points location depending on the type of light distribution are indicated.

Lighting systems that are not up to standard will have an impact on eye fatigue so that the work results of the staff are not optimal. This problem can be solved by designing a lighting system according to the standards that have been determined through the results of previous studies. The 1st floor of the Faculty Engineering, Universitas Medan Area building requires lighting improvements to provide comfort to all staff and lecturers. This research was conducted by measuring the value of light intensity in each room and improving the lighting system which was analyzed through the shape of the room, the color of the walls, and the position of the lights. The results of the study provide additional light points and the position of the lamp according to the utilization.
