Abstract

Objects can be interpreted as all inanimate and living things that have various shapes and sizes. For humans to determine the presence of objects, to classify and estimate the distance of objects around them is not difficult. But for a computer to do the work mentioned above with an accuracy level that reaches up to greater than 90% is not easy. Object detection is important in the field of computer vision because it is used to monitor and track objects, while robots that use cameras as sensors are used to avoid obstacles, follow objects, classify and so on. Therefore, the purpose of this study was to determine the level of accuracy of the CNN method in classifying objects. The steps used to complete this research were literature study, collecting digital image data, determining training, and testing data, designing the CNN program, conducting training and testing. From the results of testing the CNN method that has been carried out, it is known that the level of accuracy in classifying objects reaches 98%.

Abstract

The problem of environmental pollution has been a concern for a long time and continues to be an important issue today. One form of pollution that is very detrimental is air pollution, which causes a decrease in air quality and disrupts its normal function. . The ISPU Scale usually consists of several categories that describe the level of air quality, such as the range 1-50 is said to be "Good", the range 51-100 is said to be "Moderate", the range 101-200 is said to be "Unhealthy", the range 201-300 is said to be "Very Unhealthy", and a range of 301+ is said to be "Dangerous". To monitor the level of air pollution, it is necessary to use a tool that can measure air quality accurately. Indoor pollution, as is often the case in office environments, is one of the most serious threats to the health of modern society. A worker can spend up to eight hours a day in the room. The air we breathe everyday comes from the building's air duct system. However, these duct systems not only circulate air, they can also spread contaminants from one room to another. Therefore, it is important to maintain indoor air quality for the comfort and health of workers, because this has a direct impact on their productivity. Based on this, an idea emerged to develop a prototype detector of carbon monoxide gas that is sensitive to indoor air pollution using a microcontroller and web-based. This research begins with analyzing and designing the system, both in terms of hardware and software. After that, the next step involves coding and programming configuration and setup on the Thingspeak web. The last stage is testing tools and systems to ensure that they operate according to the plan that has been set. This system is designed to be able to detect and monitor the level of air pollution, as well as provide a graphical display on Thingspeak. This tool works by using a microcontroller to read the MQ-135 sensor attached to the Ardino Wemos ESP8266. This sensor is used to measure gas levels in a predetermined room. The tool will connect to the Wi-Fi hotspot on the Android device to provide notifications via Thigspeak based on a graph

Abstract

Sistem absensi karyawan yang efisien sangat penting dalam meningkatkan kinerja dan akurasi pencatatan kehadiran. Penelitian ini bertujuan untuk mengembangkan sistem absensi karyawan berbasis web menggunakan metode QR Code di Kantor Desa Cinta Raja. Metode Pengumpulan data dilakukan melalui observasi, wawancara, dan studi pustaka. Hasil penelitian menunjukkan bahwa sistem absensi berbasis QR Code lebih efektif dibandingkan dengan metode manual, baik dari segi kecepatan pencatatan maupun akurasi data kehadiran. Perbedaan signifikan terlihat pada efisiensi waktu, di mana sistem berbasis teknologi mampu mengurangi kesalahan pencatatan dan mempercepat proses absensi. Dengan demikian, sistem ini dapat menjadi solusi yang inovatif untuk meningkatkan efisiensi administrasi kehadiran karyawan di lingkungan pemerintahan desa.

Abstract

Perkembangan teknologi informasi telah mendorong berbagai sektor usaha, termasuk usaha Food and Beverage (F&B), untuk mengadopsi sistem informasi berbasis komputer guna meningkatkan efisiensi dan akurasi dalam proses operasional. Penelitian ini bertujuan untuk merancang dan membangun aplikasi pendataan penjualan berbasis web pada Ausy Coffee, sebuah usaha F&B yang belum memiliki sistem pencatatan penjualan yang terkomputerisasi. Metodologi pengembangan sistem menggunakan pendekatan rekayasa perangkat lunak dengan bahasa pemrograman web dan database MySQL. Hasil dari pengujian aplikasi menunjukkan bahwa sistem yang dibangun mampu mencatat penjualan secara akurat, menampilkan laporan keuangan bulanan, serta memudahkan pengambilan keputusan dalam pengelolaan stok dan evaluasi keuntungan. Sistem ini diharapkan dapat menjadi solusi efektif bagi usaha serupa dalam mengelola data penjualannya.
