IMPLEMENTASI SENSOR ULTRASONIK PADA TEMPAT SAMPAH PINTAR BERBASIS IOT

Krissantus Andrie Verryando — 2024-05-20

The increasing problem of waste management has become a global issue that requires innovative solutions. The main cause of this issue is the awareness of each person. In today's digital era, smartphones are a top priority in doing activities because efficiency becomes a convenience as any example is within reach. The ease of getting information becomes a reference in making decisions. The rise of technology that is increasingly sophisticated in the last decade has made everything around us also touch technology according to the needs of its users. In this regard, this research aims to design and implement a smart trash can connected through the Internet of Things (IoT) using ultrasonic sensors. The system is designed to automatically open and close the trash can, detect the presence of users who will throw away the trash, detect the level of trash can contents, send data to the Telegram application, and provide notification of almost full trash can notifications to users in real- time or manually by interacting through a chatbot on the Telegram application according to the data sent by the ultrasonic sensor. This research uses hardware and software design approaches and quantitative methods. Arduino Uno R3 is used as a microcontroller that works as an electronic circuit capable of processing data and changing it as a reaction to open and close the trash can automatically. The ultrasonic sensor is used to detect the user and measure the level of the bin contents, and the electronic components connected through the IoT network send the data to the Telegram application. A web-based application and a mobile application were developed for the bin monitoring system that is useful for monitoring the status of the bin and providing notifications to users. The results showed that the system was successful in detecting the content level of the bin with a high degree of accuracy. The use of IoT technology enables efficient monitoring and better decision- making in waste management. In addition, the use of these smart bins can help reduce user manual labor and optimize garbage collection in the neighborhood.

PENERAPAN SISTEM PENCARIAN DAN PEMINJAMAN BUKU BERBASIS ANDROID PADA SMP N 3 SUNGAI AMBAWANG

Florensius Balbo — 2024-05-20

This application is built consisting of two sides, namely, Android-based application users or book borrowers and a website-based server for librarians as admins. The android application will be used by borrowers in searching and borrowing books online, using students' personal smartphones, while the website application will be used by librarians to record books in the school library. The process of searching for books can be done on the android application, while the process of borrowing books can be done if the borrower is already a member of the library. In order to become a member of the library, borrowers must enter their personal data on the register page. The process of borrowing books can be done if the book you are looking for is available in the school library. In the android application students can borrow books, then they can take books to the school library section and the admin will confirm the status of borrowing books. The process of fines for borrowers of books can be carried out if the borrower exceeds the borrowing time limit set by the school library administrator and the process of paying the fine is carried out by visiting the school library directly, as well as returning the books being borrowed. The admin will confirm on the website server application the total fines and the fine payment process can be carried out. Likewise with the process of confirming borrowing, returning and renewing books which can only be done by the library admin.

PENGEMBANGAN SISTEM PENJUALAN DAN PERSEDIAAN BARANG BERBASIS DESKTOP PADA USAHA DAGANG AFEN

Bunga Nanda — 2024-05-21

Usaha Dagang Afen is a is a business that sells various accessories such as: wallets, bags, jewelry boxes and so on. This business has not yet implemented a computerized based information system and has not used a database as a storage. Usaha Dagang Afen still uses a conventional system where there is no record of incoming, outgoing, and quantity of goods, so there is often a shortage or shortage of unknown goods which hinders selling, and inaccurate accounts receivable. The method of data collection carried out by the author is by interview, observation and literature study. The analysis technique used is an object-oriented analysis technique with the Unified Modeling Language (UML) as the modeling language and StarUML Ver 5.0.2.1570 as the modeling application. The system design application used is Microsoft Visual Studio 2010 as the programming language, MySQL ODBC 5.3 Unicode Driver, XAMPP Control Panel ver 3.3.0, MySQL ver 8.0 as the system design and database processing application. Based on the results of the research conducted, the authors produced a desktop based selling and inventory application that helps minimize the occurrence of incomplete invoices and uncontrolled inventory.

PERANCANGAN SITUS PENJUALAN ONLINE PADA TOKO 88 JUNGKAT

Darmadi Andrew Fernando — 2024-05-21

The conventional sales system at Toko 88 Jungkat has resulted in various issues like slow service, the unavailability of a reporting system, and inaccuracies in sales and inventory data recording. The research method used is the descriptive research method. Data collection techniques include interviews, observations, and literature studies. The applied system analysis and design technique is object-oriented, utilizing Unified Modeling Language (UML) diagrams as the modeling tool. The system design applications use HTML, CSS, PHP, JavaScript, Visual Studio Code, XAMPP, StarUML, MariaDB, and Bootstrap. The proposed online sales system allows customers to access product information instantly, place orders and make payments without queuing, track shipped orders, download order invoices, and request returns. In addition, the admin can manage all transactions, while the admin and the owner can do sales reports, inventory records, and print returns. Computerized sales systems offer more accurate, systematic, and error-minimized results due to the automation provided by the system. It is necessary to have training for website admin positions and further analysis of a larger target market by a selling goods system in large quantities.

SIMULASI PENGENALAN WAJAH DENGAN METODE LOCAL BINARY PATTERN HISTOGRAM (LBPH)

Romanus Pradista — 2024-05-22

The principle of facial recognition is that the facial object captured by the camera will be processed and compared with all the images of the face in the existing data set, so that the identity of the face is known. One of the applications of facial recognition is to conduct attendance with individual faces. In this study, a system was created that can detect and recognize a person's face which is using the Local Binary Pattern Histogtram (LBPH) method. The programming languages used are Python, openCV and Numpy modules. The Javascript programming language is used for the user interface, so the user scans the face through a browser with a MySQL database to store the identity data and name of the owner of the face. The results of the study using the LBPH face method were successfully identified and the data was saved to the database used for attendance data. The amount of training imagery data and the distance of the object to the camera as well as the quality of the camera resolution affect the results of facial recognition so several tests were carried out. Too far away about 120 cm and above the camera, the face cannot be recognized well because the system finds it difficult to capture the pixel area of facial features. The large number of training images for each test image is also quite influential, the more training images for each test image, the better the percentage of recognition success and vice versa. Furthermore, testing with different camera resolution qualities, the higher the resolution of the camera used, the accuracy of detection and recognition becomes accurate and faster.
