Abstract

A corporation makes a choice based on sales forecasts for the next period based on residual inventory from the previous period as well as forecasts of the number of requests in the next period. A forecast is an estimate of future demand based on some predictive characteristic, which is frequently based on time series, historical data. And because these things are unknown, we need the correct way to overcome the uncertainty of future sales in order to avoid issues in sales. The length of the forecast decision-making process is affected by the problems encountered. The fuzzy mamdani approach, also known as the max-min method, is used in this sales prediction procedure to map issues from input to output. Based on the results of the calculations performed in this approach, it may create sales forecasts with the necessary data's accuracy and develop a useful system with an efficient system display that is simple to use.

Abstract

Sensor ultrasonik digunakan dalam aplikasi kapal untuk mendeteksi jarak antara kapal dan benda lain, seperti perairan dangkal atau dermaga. Sensor ini bekerja dengan memancarkan gelombang ultrasonik dan mengukur waktu yang dibutuhkan untuk gelombang tersebut kembali setelah memantul dari benda yang diukur. Namun, sensor ultrasonik juga memiliki beberapa keterbatasan, seperti pengaruh lingkungan dan interferensi dengan gelombang suara lainnya. Oleh karena itu, perlu dilakukan penyesuaian terhadap sensitivitas sensor dan kalibrasi secara teratur untuk mendapatkan hasil yang akurat. Dalam penelitian ini, dilakukan pengujian terhadap sensor ultrasonik pada kapal dan dihasilkan nilai akurasi pengukuran yang tinggi dengan menggunakan metode kalibrasi yang tepat. Hal ini menunjukkan bahwa sensor ultrasonik dapat digunakan sebagai solusi dalam memperbaiki kesalahan navigasi kapal dan membantu mencegah terjadinya kecelakaan.

Abstract

In the era of increasing digitalization, the need for an efficient and accurate attendance system has become very important, especially in academic and professional environments. This research aims to design and develop a prototype presence model using RFID RC522 technology, which can provide an effective solution to various problems that exist in conventional presence systems such as data inaccuracy, presence manipulation, and inconvenience of use. The method used in this research includes hardware and software design. The hardware consists of an RC522 RFID module connected to an Arduino microcontroller, while the software was developed using the C++ programming language to manage communication between the RFID and the microcontroller, as well as storing attendance data in a database. Testing was carried out on a sample group of users to evaluate the accuracy and speed of the system in recording attendance. The research results show that the RC522 RFID-based presence system can identify and record user presence with a high level of accuracy and fast response time. This system has also proven to be more secure and difficult to manipulate compared to traditional presence methods such as manual signatures or identity cards without RFID technology. Additionally, users report increased convenience in the attendance recording process as it does not require direct physical contact with the device.

Abstract

Developing a user interface and user experience for a web-based psychological test application at Universal University, especially the Uvers Career Center (UCC), is a technology that is needed to make the appearance of an application non-monotonous and dynamic. Previously, psychological test applications that had been developed by previous research did not meet the UCC's own standard requirements. The data source that will be used is qualitative data and uses a usability testing method with the aim of making it easier for users to carry out psychological tests with a display that is in accordance with what is required by the UCC. The final result of the research is designing the user interface and experience of the MindQuiz application which has a usability score of 83.11.
