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.

This research was conducted with the aim of detecting and neutralizing cigarette smoke in a room using a messaging applicationâ€”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.

The correct calculation of the cost of production is essential for a manufacturing business. The accuracy of the calculation can increase business competitiveness through a cost leadership strategy. This activity aimed to provide training in determining the cost of production in Umi Wiwik's business by using a comparative analysis of variable and complete costing methods. This activity was carried out at the Umi Wiwik business in Padang Tae Ampiang Parak, Sutera Sub-district, Pesisir Selatan, West Sumatra. The method used descriptive analysis by applying variable costing and complete costing to calculate the cost of production of tuna nuggets and tuna meatballs. The community engagement activity was carried out by presentation, discussions and exercises for 15 participants. The calculation result showed significant differences between variable costing and full costing implementation. The cost of production using the variable costing method is lower than the entire costing method. It allows Umi Wiwik's business to set the selling price of tuna nuggets and meatballs at a lower price, with the same profit target, than competitors and make it more attractive to potential consumers.

Eucheuma cottonii is a type of seaweed that is cultivated in the coastal area of Nagari Sungai Pinang, Koto XI Tarusan District, Pesisir Selatan District, West Sumatra Province. Before being sold, seaweed farmers must dry their seaweed first, because what can be sold is dried seaweed. Drying the seaweed takes two to three days depending on the weather conditions. In this research a seaweed drying system has been designed with a tool that rotates the seaweed in the drying chamber. In this rotary drying system, the soil moisture sensor is used which functions to detect the moisture content of the seaweed, if the moisture content of the seaweed is still read > 30% then the microcontroller turns on the relay which forwards instructions to the heater and the DC motor starts rotating the player container. The DS18B20 sensor is used to detect the temperature of the drying chamber, if the total moisture content of the seaweed is 30%, then the state of dry seaweed has been reached. Tests have been carried out to determine the difference in time required between the seaweed drying process using the system that has been built in this study and the seaweed drying process that utilizes direct sunlight. To achieve a moisture content of 30% in the seaweed drying process with the system designed in this study it takes an average of ±50 minutes, while using direct sunlight it takes ±9 hours to dry the seaweed.

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%.

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.
