<![CDATA[Soybeans are one of the main ingredients for making tempeh. Most of the tempeh production businesses still use the traditional system of washing soybeans. Washing soybeans is still done manually using a washing drum filled with water and stirred by hand, thus draining the workforce. In the process of washing soybeans, there is still direct contact with parts of the human body, resulting in unhygienic soybeans. From these problems, the solution is to make a machine that can wash soybeans in tempeh production which aims to facilitate washing soybeans and produce clean and hygienic soybeans. The soybean washing machine process uses a screw conveyor system with an AC motor 1 phase 1 HP 1420 Rpm as a driving force and a DC 12 V 25 W water pump to drain water into the watering canal. The machine can wash 5 kg of soybeans for 10 seconds, and produces a motor rotation of 271.2 Rpm, voltage 229 V, current 2.58 A to produce clean and hygienic soybeans.]]>

<![CDATA[Room security is a very important thing to prioritize. One of the solutions to prevent crime levels needs to be equipped with a security device or a device capable of monitoring a room with the ability to detect the presence of an unwanted person. Therefore, this study designed a tool to monitor rooms based on the Internet of Thing (IoT) with surveillance cameras, which is one way to monitor the situation in a room. This system combines the use of the pir sensor, the raspberry pi camera module, and the raspberry pi, in order to be able to find out the condition of the room in the form of photos sent and also use bot features on internet applications, namely telegram messenger. This system is more efficient because it uses storage from telegram, and also the system will send notifications via telegram bots. So that the user can take action as soon as possible if things happen that are not desired. When the pir sensor detects movement in the room, the camera takes a photo and then sends it to the user's telegram bot account and the buzzer sounds as an early prevention of crime.]]>

<![CDATA[Hydroponics is a way of farming that does not use soil, but only uses water that contains nutrients. The growth of hydroponic plants can be influenced by various factors, one of which is a lack of water nutrition in hydroponic plants. Therefore, this study aims to create a system that functions to control water nutrition, as well as the availability of sufficient water in hydroponic reservoirs. This control process uses NodeMCU esp8266 and processes sensor data and then sends it to firebase which will be displayed to Android with Internet of Thing (IoT) technology. If the nutritional condition being monitored is reduced, this nutrition control device will receive input from the sensor to add nutrients automatically. The addition of nutrients uses an on-off control system, when the TDS sensor reads the water nutrients are reduced the nutrient pump will be on until it reaches the initial nutrient setpoint, then the nutrient pump will be off. The result of reading sensor data obtains the percentage error for the Total Dissolve Solid (TDS) sensor with a comparison of TDS meter of 5.746%.]]>

<![CDATA[Automatic monitoring of water volume during gallon filling is a technology increasingly important in the water filling industry, particularly for ensuring accuracy and efficiency in the distribution process. This tool aims to monitor the water flow rate during the filling of mineral water gallons using a Flow Sensor. An Arduino Uno serves as the controller for this system. When the water pump is activated to fill the gallon, the flow sensor measures the amount of water flowing through it by generating pulses, which are then sent to the Arduino Uno for processing and calculation of the water flow rate. The results of these calculations are displayed on an LCD screen, stored in EEPROM memory for long-term data recording, and can be monitored remotely via a smartphone. This gallon water filling tool has a system accuracy percentage of 98%.]]>
