Culinary businesses in Indonesia, such as Brownies Cinta Karanganyar, face challenges in helping consumers choose products with the best taste. This study aims to implement a Brownies Cinta menu recommendation system using the Content-Based Filtering method with the cosine similarity algorithm. The system was developed through the SDLC Waterfall stages: planning, design, implementation, testing, and maintenance. The TF-IDF algorithm is used to calculate the initial value, which is then processed with cosine similarity to produce accurate recommendations. The test results show that the "Lapis Kukus Fruity (Regular)" and "Brownies Oven Almond (Regular)" menus have the highest cosine similarity values, reaching 0.950. In contrast, the D19 document with the lowest cosine similarity value is considered irrelevant. In conclusion, the developed content-based recommendation system can provide the best and most relevant recommendations to users. The use of the TF-IDF and cosine similarity algorithms has proven to be accurate, increasing consumer satisfaction in choosing products. This system helps Brownies Cinta consumers determine the products they want to buy, facilitating the menu selection process.

This study aims to create a reading system for the running of the Gerber Auto Cutter machine and monitor the temperature in the vacuum mechanism area of the machine, which can provide notifications to the telegram chatbot and Arduino IoT cloud. In this case, the reading of the running machine functions to detect machine usage in real time and accurately, both when the machine is turned on and when the machine is running for the fabric cutting process in production. From the reading of the running machine, data can be taken on how long the machine and knife have been used, so that they can be programmed to display notifications on the telegram chatbot when a certain usage time has been reached. For reading the temperature in the vacuum mechanism room, it functions to monitor and provide notifications when it has exceeded the temperature threshold that can be tolerated by the electrical system in the vacuum system. In this case, the condition of the machine stopping operating due to damage to parts can be minimized. This study uses a qualitative method by means of observation, interviews, literature studies and case studies at PT. Brothersindo Saudara Sejati which is a machine supplier. The author uses the waterfall method for software development and prototyping for hardware development.

The use of conventional air conditioners is often inefficient and energy-wasteful. Users usually set the temperature manually, which can result in excessive energy use. In addition, the lack of an effective monitoring system makes it difficult to monitor air conditioning conditions, such as room temperature and humidity. This research aims to create an Air Conditioner monitoring and control device that can work automatically to control the temperature in a room and can be controlled through IOT. A temperature monitoring system and remote air conditioning controller is a tool that can be used to monitor room temperature conditions and control the temperature in the room to match what we want. This tool uses proportional type control (P) with a monitoring system utilizing Internet of Things (IoT) technology. The ESP 32 microcontroller is used as a microcontroller-based control device that has been facilitated with a wifi module. To measure the room temperature, a DHT11 sensor and an infrared LED are assembled and connected to a microcontroller as a data transmitter to the air conditioning unit. This system uses the arduino IDE application which has features to monitor and control the temperature in the room. The way this tool works is as a remote that controls the Air Conditioner to get the desired temperature in the room and the temperature read on the device can be monitored on a smartphone remotely.
