<![CDATA[Security is very important necessary for everyone, one of that security’s needed is the savety of valuables both publicly and more especially at home. Because many of thieves who come direcly to the house, the door was forced open, ande forgot to close the door, the thefs cases increased. Therefore the system can detect movement in front of the door using a PIR sensor design, gives a warning when the door is forced open and can open or close the door automatically. This research uses the Telegram Bot to send orders and receive notifications in the form of text or images. The PIR sensor will give notification when a movement is detected in front of the door, onece detectedit will turn on the LED light and take a picture of the movement, a warning from the system in the form of buzzer. It will also serve as a warning when the door is forced open. When the user enters the open command via Telegram Bot, the door will open and close by itself. The error of the tested system is 0%, all components can work as expected.]]>

<![CDATA[This study aims to create a system that can monitor gas cylinders where this device consists of two systems, the first is a system to measure the weight of 3kg LPG gas cylinders to find the remaining gas which will then be displayed on the LCD, and the second the system gives a notification (alarm) if there is a gas leak via SMS. This system consists of Arduino UNO Microcontroller components, Load cell Sensor, MQ-6 Sensor, and SIM800L GSM Module. For overall system testing, the load cell sensor system can display a percentage of the weight value obtained an error rate of 0%, this indicates that the formula used in the program runs according to what is desired. In the MQ-6 sensor system can make the buzzer on at a value >= 700 ppm, the results of the buzzer can live when the detected gas value >= 700 ppm, this is as desired. In the sim800L gsm module system can send leak notifications, the results obtained that the module can send SMS notifications. And the system turns on the buzzer when the LPG gas has reached the minimum limit, the results obtained by the buzzer will sound when the remaining gas value <= 16%. Based on tests conducted on this system the system can measure the desired weight of the cylinder to look for the remaining gas in the form of a percentage and detect a gas leak and then send an SMS notification.]]>

<![CDATA[This research was conducted with the aim of detecting and neutralizing cigarette smoke in a room using a messaging application—in this term is Telegram as notification to the user. The system is also equipped with room temperature and humidity monitoring features. In a room that is exposed to cigarette smoke does not have good air circulation, it will cause cigarette smoke not to come out quickly, this problem which will interfere with health, because of the smoke that is inhaled. In this case, we need a system that can detect and neutralize cigarette smoke. For cigarette smoke detection using the MQ-7 sensor, the DC fan and Ozone Generator will automatically turn on if the value on the MQ-7 sensor is greater than or equal to 74 Ppm and the system will also send a notification via Telegram that cigarette smoke is detected. This serves to neutralize air contaminated with cigarette smoke in the room. To monitor room temperature and humidity using the DHT11 sensor and the results of room temperature and humidity monitoring will be displayed on the mobile application.]]>

<![CDATA[A dormitory is a temporary residence for college students in which they are charged with a certain cost for a certain period of time. The payment for water usage in a dorm includes bathrooms that use PDAM (municipal waterworks). The management of water usage in the dorms is not recorded properly due to the absence of a flow meter in the water pipelines. Monthly water usage in each dormitory room remains uncertain depending on the tenant's need. Therefore, a system was designed to monitor the water usage in dormitory rooms. This system relies on a waterflow sensor component to measure water discharge, an LCD to display a real-time volume and costs, a solenoid valve to stop the water flow when the bill is due, a relay to control the work of the solenoid valve, and ESP32 to process data includes discharge data, volume data, and cost data. These data are sent to the server and stored in a database. Then, the water usage and the monthly cost can be accessed on the website. The system adds a lithium battery, a TP4056 charger module, and a boost converter. The testing was done by designing 3 tools with the same components and functions. The error value on device 1 is 0.5%, device 2 is 0.2%, and device 3 is 0.1%. The success ratio of each function of the system as a whole is 100%.]]>

<![CDATA[The culinary business is the top two contributors from the manufacturing sector (6.66%). The Association of Indonesian Food and Beverage Entrepreneurs (GAPMMI) estimates that the food and beverage industry will grow by 7% by the end of 2022, this shows that the basic needs business such as the food or beverage business has good business prospects. A restaurant at certain hours such as lunch, dinner and on certain days, will be the busiest time to visit. It is at this time that the service of a restaurant will find it difficult to serve customers, and will experience a decline in service. At this time there are still many restaurants that check tables manually, by checking each table in turns. One technology that can be used to help in this situation is to use an ultrasonic sensor, this sensor can detect the presence of an object or certain objects above the sound waves of 20 kHz to 2 MHz. This can help business people to improve restaurant waiters to be better, by creating a system that can detect the arrival of customers at the restaurant table with an identifiable time and develop with various other capabilities. The research focuses on monitoring table availability by detecting the presence of customers in restaurants.]]>

<![CDATA[The development of an Internet of Things (IoT)-based smart room system in a Very Important Person (VIP) room was carried out using a NodeMCU ESP8266 microcontroller, a Passive Infrared (PIR) sensor, and the Blynk application. The system is capable of detecting human presence at a distance of up to 5 meters with a detection angle of 35°-145°, and automatically controlling electronic devices such as lights and music players. Additional manual control is carried out through the Blynk application for volume and equalizer settings. Testing shows that the system successfully reduces electricity consumption by turning off devices when no users are present. The PIR sensor detection success rate reached 98% in a 7 x 4 meter room, with a system response time of less than 2 seconds. The system also supports light control through two methods: input from the PIR sensor and the Blynk application. The overall implementation demonstrates operational efficiency, ease of management, and potential energy savings in an IoT-based VIP room facility.]]>
