Design and Build Automatic Catfish Feeding System Biofloc
Get PDFCatfish is one of the results of freshwater cultivation that is popular with the community and has economic value. The high public interest in catfish, is one of the factors cultivators increase production yields. Feeding and treatment of catfish pond water still uses human resources. This reduces the efficiency of the farmer and allows for negligence in providing feed and water treatment if the farmer has a large number of ponds or more than one. In this study, it is proposed to control and monitor feeding and water treatment with a biofloc system automatically and regularly, with the catfish biofloc system also obtaining natural food when the feeding schedule is raining. It takes a wireless sensor network system as a control system, fc-37 sensor, Total Dissolved Solids (TDS), Loadcell, Real Time Clock (RTC). All of these sensors will be integrated with the Arduino Uno which will then send data from each sensor to the Raspberry Pi with the nRF24l01 communication module. The results of this study are monitoring the appearance of the web server processed by the Raspberry Pi which shows feed availability, pond conditions and turbidity levels. From the experimental results, it is found that the planned system can work well and as desired
A Geolocation Visitors to the Polinema Library using QR Code and OTP Code on Internet of Things based Smart Locker
No full textThe library is one of the rooms or facilities used as a learning center. Data on library visitors with a locker at the Polinema library is in a different place, where the Polinema library locker are outside the library area which can be misused for storage of public goods. Visitors only enter the library area to ask for locker keys and leave items in the lockers, but visitors do not visit the library. To overcome this, a system was designed using a QR Code scan that can be used as a library visitor data system that can directly open the locker door using an OTP code, after getting the OTP code visitors can enter items and then lock them automatically. Application login testing can be done according to the system. Testing of open/closed locker markers and admins can access the locker if someone leaves the Library area. The coordinates of the GPS points for 4 visitors who came out of the Library area with a distance of 25,049m, 38,839m, 56,502m, and 64,904m were proven with a maximum distance of 20m. Comparison of the distance between Formula Haversine and Google Maps (distance between 2 points) obtained an accuracy rate of 0.236%

The material that was recently used in decorations is styrofoam. The purpose of this research is to design a CNC machine to get good results and neatly cut Styrofoam using a hot wire. This research also contributes to solving problems with Styrofoam cutting usually a problem with detailed and complicated work that can be solved automatically using a CNC machine. Tool hardware design requires Bluetooth connection, driver to the stepper motor, driver A4988 to CNC shield, and step down to the heating wire. Software design includes uploading GRBL firmware, creating G-code using Inkscape Software, and connecting Android applications to CNC machines. The result shows that for 2-dimensional styrofoam cutting with 1cm thickness, the best results are obtained in the range voltage of 7.4-8.5V. Styrofoam also testing is carried out using the same voltage 8.5V but with different feed rates and the result with 400 mm/min shows the best cut performance. The results of cutting 3-dimensional Styrofoam showed that for a voltage of 8.5V, a feed rate of 300mm/min, and a thickness of 10cm Styrofoam produced the best cutting texture from others. This shows that the heat generated by the wire is directly proportional to the feed rat
Design Stunting Detection Applications Using Artificial Intelligence on Android Devices
Get PDFIn this era, careful attention is needed to the development and growth of children, so that if there is an abnormality it can be detected as early as possible. One of the main factors that affect the growth and development of children is the nutritional factor. Lack of knowledge about growing children causes parents not to realize if their child has a disorder such as stunting. Stunting must be detected as early as possible so that solutions can be given to prevent it from happening. These problems must be corrected immediately and the development of the child is not disturbed. Therefore we need an application that can detect stunting disorders in children from an early age so that they can be handled quickly and precisely. In making this application, it will detect the child's height and weight through the camera to perform a nutritional check that detects the child is stunted or not. This application uses artificial intelligence or Artificial Intelligence based on android. Weight measurement results will be sent from the weighing system to the application using the Bluetooth address for the connection so that the weight results can be displayed on the application. Height measurement is carried out using the camera in the application which will detect the child's height through an image. The test results show that the stunting detection application is very helpful for parents to observe the growth and development of children without having to use and calculate children's nutritional problems manually.
