Abstract

Abstract―Vehicles are a secondary need for humans that can be postponed. However, Indonesia has a tropical climate, so everyone needs a vehicle as a means of transportation, therefore every year vehicles increase rapidly as the population increases. Indonesia is currently a fairly large vehicle sales market. So with the increasing number of road vehicles getting out of control, the result is congested roads, as a result of which traffic violations and accidents are increasing every year. Therefore, by making an optimization tool for using data loggers on two-wheeled vehicles, we intend to monitor every vehicle on the road. However, this research focuses on output data such as accuracy and delay of real time IoT-based vehicle data and data loggers that are stored automatically on SD memory cards in two-wheeled vehicles. The research results from the Infrared sensor data sent to the Blynk server, there is a fairly long delay and the data stored on the SD memory card is quite good, only has a delay per one second, the voltage sensor here plays a good role in real time data and data on the SD memory card because there is no delay the old ones are in sync with actual events, while the realtime control panel output results to the Blynk server using the NodeMCU ESP8266 produce realtime output, and the use of relays as controllers of the tools that have been made has been tested and obtained satisfactory results.

Abstract

Since Indonesia is an archipelagic nation, the economic sector of fisheries, particularly catfish farming, is one that has a lot of potential. However, a lot of catfish breeders still count their fish seeds by hand, which is time-consuming, particularly in hazy water conditions. Therefore, an automatic catfish seed counter is required in order to make calculations simpler, quicker, and more precise even under hazy water situations. In order to address these objectives, the prototype of a catfish seed counting device in murky water is shown in this study. This tool's prototype was created and constructed utilizing an Arduino Uno as the processor, two different types of sensors as inputs, and an LCD and buzzer as outputs. The FC-51 proximity sensor is used to count the quantity of fish seeds, while the turbidity module sensor measures the amount of turbidity in the water. With a total sample size of 50 fish fry, the test was run under three conditions for the turbidity level of the water samples: 6.21 NTU, 11.10 NTUs, and 16.38 NTU. According to the test results, the catfish seed counter in murky water performed admirably and was fairly accurate. An average error value of 3.2% is achieved with a water turbidity value of 6.21 NTU. An average error value of 6.8% was discovered at the turbidity value of 11.10 NTU. Finally, an average error value of 18.8% was discovered at a water turbidity value of 16.38 NTU. In order for this catfish seed counter to be effective, water turbidity values below 13 NTU with a minor error of 10% are preferred, particularly water turbidity values below 8 NTU with a little error of 5%.
