Cattle cage is a term that refers to a structure used to house farm animals or animal homes. The structure might be in the form of a container, a building, or something else entirely, depending on the type of animal being farmed. Because most cattle shed doors are slotted or padlocked, there is a high rate of theft from irresponsible individuals seeking to take livestock without permission. The primary objective of this research is to devise a security system capable of keeping cattle pens secure and free of thieves or burglars that cause livestock loss. The author chooses the Atmega 328 microcontroller because it features a Harvard architecture that separates program code and data memory to maximize work and parallelism. Additionally, this circuit may be connected to an Arduino Uno to create a variety of electronic circuits ranging from simple to complicated. LED control, helicopter control, servo drive control, and robot control can all be implemented by adding specific components. Thus, a prototype was created for an automatic door safety system that employs an infrared sensor to detect the presence of animals and automatically opens the entrance, locking it with a password and ringing a buzzer in front of the farmer's house if the password is incorrect. This tool was created to help minimize cattleÂ losses due to theft.

River water that overflows or is at an uncontrolled height can cause flooding and environmental damage. Therefore, the development of a river water level detector that can provide early warning is very important. In this research, we propose a river water level detector using ultrasonic sensor with sound output based on Arduino Uno microcontroller. This device is designed to measure the level of river water by utilizing the principle of ultrasonic wave reflection. The ultrasonic sensor is installed above the river and sends ultrasonic waves to the water surface. The waves are then reflected back to the sensor after reaching the water surface. The travel time of the reflected wave is used to calculate the distance between the sensor and the river water surface.The Arduino Uno microcontroller is used to process the distance data obtained from the ultrasonic sensor. When the water level exceeds the specified limit, the microcontroller will generate a sound output as a warning. A speaker is connected to the microcontroller and will emit different sounds depending on the water level.This tool has advantages in terms of accuracy and responsiveness. By using ultrasonic sensors, measurements can be taken in real-time and provide water level information with high precision. The voice output also allows the information to be delivered directly and effectively to the user. The test results show that this river water level detection device can work well and provide early warning when the water level exceeds the specified limit. The success of this tool is expected to help in flood risk management and environmental conservation.

Determining the right foundation shade is a common challenge faced by make-up users, especially for those who have no experience in choosing beauty products. To solve this problem, this research designs a web-based application that can recommend the appropriate foundation shade based on the user's complexion. This application was developed using the Rational Unified Process (RUP) Model, a systematic and structured methodology for software development. The RUP model consists of four main phases: Inception, Elaboration, Construction, and Transition. In the Inception phase, user and stakeholder requirements are identified, as well as initial project planning. The Elaboration phase focuses on system analysis and design, including modeling of functional and non-functional requirements. The Construction phase involves developing and testing the system based on the design that has been created. Finally, the Transition phase focuses on application deployment and user training. This application uses several recommendation algorithms to determine the foundation shade that best suits the user's skin color. User data is obtained through manual input or through photo uploading, which is then analyzed using image processing technology. The results of this analysis are used to identify the user's complexion and provide appropriate foundation shade recommendations. The implementation of the web-based application allows easy and flexible access for users. The application is also equipped with an intuitive and user-friendly interface, making it easier for users to operate and get the desired recommendations. In addition, the app is designed to be continuously updated and adapted to the latest trends in the beauty industry, as well as user feedback. Through the application of the RUP Model, the development of this application is expected to run more efficiently and structured, producing quality products that meet user needs. This app not only helps users in determining the right shade of foundation, but also improves the overall online shopping experience of beauty products.

In building a web-based cleaning material sales information system, the Business to Consumer (B2C) method is applied with the aim of improving a more efficient and effective sales process and reaching a wider market. This research builds a web platform that facilitates direct communication between manufacturers or distributors of cleaning materials and end consumers. This system was created with the aim of providing easy access to product information, transparent pricing, and a simple transaction process. The process of developing this web-based information system involves a number of steps, starting from analyzing needs, designing the system, implementing the design to conducting trials and evaluations. During the needs analysis process, the functional and non-functional needs of the users, either those who produce or use the products, were recognized. The system design includes a user interface that is easy to understand, a database that is efficient in its structure, as well as crucial features such as product listing, shopping cart, online payment methods, and order monitoring. To carry out the implementation, the latest web technologies such as HTML, CSS, and JavaScript were used along with the Laravel framework on the backend side. Product, transaction, and user information were managed using a MySQL database. The system is tested as a whole to verify each feature operates effectively and according to predefined specifications. From this research, it is evident that applying the B2C method in a web-based cleaning material sales information system increases consumer satisfaction because it provides easier, faster, and safer access to information and transactions. In addition, this system also plays a role in helping manufacturers manage sales and inventory more efficiently, as well as presenting analytical data that is useful for business decision making. Overall, the web-based B2C cleaning sales information system solution provides innovation and practicality in supporting business operations in the digital age. Not only does this technology improve the efficiency of the sales process, it also opens up new opportunities in marketing and distributing cleaning products more broadly.

Dewasa ini, kemajuan teknologi informasi khususnya komputer pribadi dan internet semakin pesat. Menggunakan komputer adalah cara yang bagus untuk menyelesaikan pekerjaan dengan cepat dan efektif. Manfaat lain internet adalah memperluas jangkauan media informasi yang dapat diakses. Terutama dalam kegiatan pendidikan yang terus memberikan ilmu kepada orang-orang yang ingin belajar. Pada masa pandemi ini, semua kegiatan tatap muka langsung dibatasi, termasuk juga dengan kegiatan mendaftar seminar yang harus dilaksanakan secara daring (webinar), maka dari itu, penulis membuat sistem pendaftaran daring dengan fasilitas yang disediakan oleh Microsoft yaitu Microsoft Power Automate sebagai solusi dari pendaftaran yang dilakukan secara tatap muka. Calon peserta akan diberikan link formulir pendaftaran yang harus diisi sesuai data diri. Setelah mengisi formulir pendaftaran, peserta akan dikirimi email yang berisi link tempat webinar akan diadakan. Setelah menyelesaikan kegiatan, peserta akan diberikan link form feedback untuk mendapatkan sertifikat keikutsertaan dari webinar. Pada tahap akhir aplikasi berhasil mengotomatisasi proses registrasi dan feedback dengan Microsoft Power Automate guna memberikan aktivitas link dan sertifikat partisipasi dalam kegiatan melalui E-mail. Pembangunan sistem ini menggunakan metode Sequential Linier (Waterfall) yaitu suatu metode pengembangan perangkat lunak tertua bersifat natural. Metode ini dijalankan dengan menggunakan metodologi yang sistematis, yang memungkinkan untuk melakukan departementalisasi dan mengontrol proses pengembangan model selangkah demi selangkah, untuk mengurangi kemungkinan kesalahan yang dibuat.
