<![CDATA[Employees who work in offices absolutely need water, for example to wash hands, to defecate, or other household needs. Water availability must be a concern of managers. But in fact, many officers pay less attention for this. They let a lot of water flows from the tank or reservoir that makes important water resources are wasted. This study aims to regulate the usage of water in office buildings so that water needs for employees are always met. The system was built by three tanks, one tank as the main water source called the central tank and two tanks as a reservoir of water that will be consumed by employees called tank1 and tank2. To measure the water level in the tank, it will use an ultrasonic sensor. If the water in the central tank has reached the minimum capacity length from the surface of the water to the sensor (≥ 20 cm), the tank manager will receives an SMS that indicates the water in the central tank is not available and needs to be refill. Tank 1 and tank 2 are filled automatically by activating the pump and opening the solenoid valve when the water is less than the maximum limit set (> 5 cm). The results showed that the system was able to send an SMS to the tank manager when the water level had reached the minimum limit with an 7.39 seconds of average delivery time. Tank 1 and tank 2 can be returned off when the water level reaches the 5 cm limit. The average success rate of filling water in tank1 was 98.46% and tank2 was 97.32%.]]>

<![CDATA[This research was conducted with the aim of drying jicama as a processed yam chips. The condition of the yam dried in an open space with low temperatures resulted in the growth of fungus on the surface of the jicama. The growth of mushrooms on jicama makes it unable to be processed and consumed. Therefore we need a system that can dry yam with a drying machine. This system can monitor the water content of jicama using a soilmoisture sensor and measure the temperature with the DS18B20 sensor in the drying room. Jicama is said to be dry when the water content is <10%, when the moisture content value (> 25%) then the jicama is wet, if the water content of the jicama (10.1% ≤ KA ≤ 25%) then the jicama is in a humid condition, so that the fan, heater and DC motor turns on. This tool is designed using the Arduino Uno, DS18B20 sensor, Soilmoiture sensor, heater, DC fan, DC motor, buzzer, relay, LCD. When the temperature is> 60 ° C, the DC Heater and Fan will turn off to reduce the temperature. The results of the yam condition will be displayed on the LCD. This is expected to be able to dry jicama quickly and produce dry jicama with good quality.]]>

<![CDATA[A Hospital is a health facility that aims to provide good health services for patients. The physical environment of the inpatient room also affects the patient's psychological condition. The inpatient room should raise optimism so that it can help the patient's healing process. Standard operating procedures in a hospital limit the number of visitors in each inpatient room. This is especially true in the class 1 inpatient room, where the number of patients is limited to two people and the maximum number of visitors limited to 2 people. However, even though the number of visitors to the hospital has been determined, many of the patients' families or relatives who want to visit violate these rules. This happens even though it has been prohibited or without the knowledge of the hospital staff. This paper describes the development of an Android based system to monitor the number of visitors to the hospital's inpatient room, streamlining the number of visitors to the hospital's inpatient room. The researcher uses a camera so that he can immediately capture the number of visitors in the room. The captured picture are processed in a Raspberry pi to count the number of visitors in the room, using tensorflow as an object detector (visitor). The system can then send notifications to the application when the number of visitors exceeds the safe limit. Researchers also use a mobile application to display monitoring results. so that with this system, the head of the hospital room and the hospital security guard can find out the number of visitors who are in the hospital inpatient room and the number of visitors who exceed the maximum limit.]]>

<![CDATA[Voice recognition technology is one of the technological breakthroughs that is currently widely used. The operation of voice recognition is only by saying commands to control devices that are integrated with the user as a tool to facilitate human activities and even replace the role of humans in certain functions. In using the dispenser, it is necessary to choose cold or hot water and pull the faucet directly on the dispenser, while during a pandemic like today, we are required to reduce direct contact with objects that are used together. The use of the dispenser also has limitations for the amount of water released because it cannot be measured in a definite amount because there has been no research conducted to regulate the amount of water that is filled into the glass used by the user. For this reason, the use of the Voice Recognition module can be used as a solution to reduce direct touch to the dispenser because it utilizes voice commands given by the user and the Waterflow sensor is used to calculate the amount of water that will come out of the water faucet on the dispenser.]]>

<![CDATA[Rabbits have their charm for breeding because of the benefits they get from rabbits. However, rabbit farming has a fairly high challenge, namely rabbits die easily because of the cleanliness of the cage. The accumulation of rabbit droppings results in increased levels of ammonia gas which are harmful to rabbits, breeders, and even the environment. In cleaning the cage, rabbit breeders still use manual methods that are ineffective and inefficient. For this reason, a systemwas created to create an automatic feces cleaning system in the rabbit cage based on IoT (Internet of Things) by utilizing loadcell sensors to detect the weight of rabbit droppings that are accommodated on the conveyor belt. Belt conveyor as a medium that transports rabbit droppings. The MQ-135 sensor is used to detect the concentration of ammonia gas and the MCUESP8266 Node as a controller and IoT as a notification and as a system control via a smartphone. Based on testing of the system, the loadcell sensor as a measure of the weight of rabbit droppings has an accuracy rate of 97.43%. The MQ-135 sensor as a measure of theconcentration of ammonia gas in rabbit cages has an accuracy rate of 99.19%. The conveyor belt can move to dispose of rabbit droppings when the weight is > 1000 grams or the ammonia gas content is > 25 ppm. Then the Telegram application bot can 100% control the system by inputting commands and can receive notifications from the system. From testing the system as a whole, the system can work according to the desired function with a 100% success rate.]]>
