TuesdaySaka Gustaf — Wed, 30 Oct 2024 00:00:00 +0700

The property industry in Indonesia is experiencing rapid development along with improving economic conditions, causing consumers to face difficulties in choosing a house that suits their preferences. Various factors such as price, location, facilities, and payment methods often make decisions complex.The Fuzzy Multi Attribute Decision Making (FMADM) method is used to determine and evaluate the best options based on the degree of suitability of all criteria, with ranking carried out using the defuzzy method. The results of this study are expected to provide practical solutions for consumers in choosing a house that suits their needs and improve the quality of property developer services in Indonesia. The author's test results show that 72% of users feel helped by this solution method.

The research aims to design an automatic cooling jacket based on the Internet of Things (smart jacket) that can be used when riding motorbikes, including online motorcycle taxis. The methods used in this research include user needs analysis, system design, prototypes, and fan speed performance testing. In the user needs analysis stage, a survey was conducted among motorcyclists to identify problems faced when riding in hot weather conditions. Next, a system design consisting of a temperature sensor and an IoT communication module was carried out. After designing the system, an automatic cooling jacket prototype was developed. This prototype is equipped with a temperature sensor that will detect the rider's body temperature level, and an IoT communication module to allow users to control the jacket via an application on a smartphone. The results of this research show that an IoT-based automatic cooling jacket can effectively reduce the body temperature of motorcyclists when riding in hot weather. In speed performance testing, this jacket succeeded in reducing the rider's body temperature efficiently. This research is expected to contribute to the development of wearable technology that can increase comfort and safety for motorcyclists. Apart from that, this research can also be the basis for developing IoT-based automatic cooling jacket products that can be mass-produced and sold on the market.

^{This research develops a prototype of a lamp setting}

^{system in a chicken incubator using DHT11 and Arduino Uno}^{R3 sensors. The purpose of this system is to control the}^{temperature and humidity inside the incubator automatically}^{to create optimal conditions for hatching chicken eggs. The}^{DHT11 sensor serves to measure temperature and humidity,}^{while the Arduino Uno R3 is used as a microcontroller that}^{processes data and regulates the heating lamp. This system}

^{works by comparing the sensor measurement results with a set}^{setpoint value. If the temperature or humidity is outside the}^{desired limits, the Arduino will turn the heating light on or off}^{to return the ambient conditions to the optimal range. Tests}^{show that this system is effective in maintaining the}^{appropriate temperature and humidity, thus increasing the}^{success rate of hatching chicken eggs. The results of this study}^{show that the prototype developed can be a practical and}^{efficient solution for theprocess of hatching chicken eggs}

Home Door Security System with Face Recognition Using ESP 32 Cam

Dimas Ricky Saputra, Winarno, Adi — Wed, 30 Oct 2024 00:00:00 +0700

The development of science and technology, especially in the fields of Electronics and Informatics, is expected to enhance room or home security systems, particularly home door security systems. Many door security technologies have been developed to prevent and ensure the comfort of homeowners when they leave their homes. Some commonly used door security systems include CCTV cameras, fingerprint sensors, voice sensors, and RFID. However, with technological advancements, these security systems have shown vulnerabilities, such as frequent errors in fingerprint and voice sensors. Based on this, to create a more secure and innovative home door security system, the authors developed a security system with face detection and a remote warning notification system using Telegram. The researchers created a door security system using the ESP 32-CAM for face detection and as a controller for the Internet of Things (IoT) system. Additionally, a manual system using a keypad for password input was also created. The results of this study include the accuracy and speed of face recognition and the speed of sending security system warning information through the Telegram application.
