Abstract

Many innovations that have been implemented by catfish breeders, where catfish are of a distinctive taste and make it a very popular thing in catfish lovers. Many farmers compete to get great seeds and are capable of producing good development and fast. This tool designer creates a tool that can be used by catfish farmer through a prototype in order to read and control the level of turbidity and automatic feeder. The level of turbidity is very important for catfish growth, where the level turbidity can band catfish growth. This tool is supported by supporting devices such as turbine sensors, ultrasonic sensors, RTC DS1307, servo motors and Atmega328 microcontrollers. The Turbinity sensor is used to measure the level of water that is going to go out from the fishpond. Furthermore, this research is also facilitated by an automatic feeder that will run according to the time that has been set by a farmer. When the feeding time is comming the servo motor will open the feed valve for a while based on food requirements time. Beside that the automatic feeder is also facilited by ultrasonic sensors that can be used for monitoring the availability of feeds when the feed in minimum the level will be active the buzzer or beeb.

Abstract

Generally, in existing dams facilitated by sluice are used to control the amount of water on that dam. This sluice is controlled by a human that has a duty to maintain the stability of the water on that dams or not to be more than existing limitation. Therefore the doorman clerk must be ready at all times and it is impossible for him to do it over time. The water gate drain human energy when open and then close it again. This tool is using as a replacement for human power. By the statement improved advanced technology development taht combines Android with Bluetooth-based Atmega 328 microcontroller instruments. This remote sluice control works automatically. The Ping sensor measures the level of the water and sluice, after that the recorded data will be processed by microcontroller and send it into the Android through Bluetooth. Besides that, the Android data that consist of water level and sluice will be captured on the LCD screen. On the other hand, the Beeb voice that getting from a buzzer will active when the level of the water sign exceeds 3 cm. In this research, Android is used as a monitoring tool and control system remotely. Furthermore, this tool also uses a DC motor in order to open and close sluice, so it makes the water gate capable to be closed and opened based on expected distance. This system hopefully can automatically open the water gate if the water level higher than a limit position by using an android control system based on operator expectation. That way there is no human power needed to open the water gate. In other words, effectiveness and efficiency will occur.

Abstract

Indonesia is commonly known as a tropical country that is rich in biodiversity of flora and fauna which has fertile land and abundant natural products, especially in agriculture. Water is one of the most important elements in agriculture, particularly in rice fields. Normally the water source is coming from lakes, reservoirs, rivers, and from other water sources through waterways to rice fields. These water channels sometimes do not work properly because the sluices that opened manually are not fully open or partly open only so it makes water is not properly channeled to the rice fields. As a result, the farmers' harvest becomes a little, even experiencing crop failure. The automatic sluice control system on the rice field irrigation is a system that will control the paddy irrigation sluice in flowing water according to the conditions of the rice fields. This system uses an ultrasonic sensor to measure the water level in the field. Then the servo motor will move the sluice to open or close according to the readings of the water level from the sensor. Then the SIM800L GSM Module will send an SMS notification that the rice fields are lacking in water and the fields have been filled with water.

Abstract

The design of a prototype train ticket detector system using RFID-based microcontrollers has been made for replacing manual methods that still require officers to check tickets. This tool becomes a useful thing for a passenger to make easier going into the train departure room. The system made consists of 2 RFID units, 2 servo motors as an entrance and exit bar, an LCD circuit, and also facilitated with a buzzer circuit. This tool works when the RFID card is pasted to the RFID reader and the Arduino Uno Microcontroller will process the data whether the RFID card contains a balance and is sufficient to purchase train tickets. Then if the balance is sufficient, then the entrance gate bar is initially closed, it will open and the prospective passenger will enter the waiting room. However, If the balance is insufficient, the portal remains closed and the buzzer will be active and the balance will be displayed on the LCD. Furthermore, by pasting the RFID card on the exit portal crossbar to the RFID reader so the portal on the exit will open.

Abstract

Generally, scales on the market still use manual models which often produce a measurement with the inappropriate result because of the accuracy problem or still have trouble with the level of precision. Furthermore, other measuring instruments are also only pendulum balances or analog scales whose output measurement results are only indicated by the pointer. The results of reading each person have different measurement results. In addition to requiring energy and a long time, the manual weighing process also has a negative impact that can harm consumers where the trader in the market usually cheats in trading. To address this problem, a digital rice weighing device is designed that is controlled by Arduino Uno by using a load cell sensor that having a capacity of 10kg (1/2 - 2.5 liters) which provides a change of resistance when there is a pressure. Changes in resistance can change the output voltage of a load cell. The voltage change that is too small so it is amplified using the HX711 and will convert it to digital in units of weight per liter. The level heavy of rice is calculated at prices corresponding to rice selected through pushbutton. The calculation results are displayed on the LCD if the rice is not enough 1 liter so the price and weight will not be displayed on the LCD. The output sound of Mini Df will mention the price based on the type of rice.
