Abstract

Unpredictable weather changes often complicate the process of drying clothes, especially when sudden rainfall occurs. To address this issue, an automatic clothes drying system was designed based on the Arduino Uno microcontroller, utilizing a Light Dependent Resistor (LDR) sensor and a rain sensor. The LDR sensor detects sunlight intensity, while the rain sensor identifies the presence of rain. When sufficient sunlight is detected and no rain is present, the system activates a DC motor to automatically extend the clothesline. Conversely, if rain is detected or sunlight intensity decreases, the DC motor retracts the clothesline into a sheltered area. The objectives of this research are to (1) Protect clothes from getting wet due to sudden rainfall; (2) Optimize the drying process by utilizing sunlight intensity; (3) Reduce manual intervention in the drying process, providing convenience for users who are frequently away from home. System testing demonstrated that the device effectively responds to weather changes, thereby protecting clothes from rain and maximizing drying during sunny conditions. This system offers a practical solution for users concerned about the state of their laundry when they are not at home.

Abstract

The administrative process of Kerja Praktek (KP) and Tugas Akhir (TA) in the Industrial Engineering Department ITEBA is still conducted manually, which often causes problems in registration, data recording, student progress monitoring, and communication between students, supervisors, and coordinators. This study aims to design a web-based information system to support more efficient, transparent, and structured KP and TA management. The method used is system modeling with the DFD approach and implemented with Glide App. The results produced an information system with key features such as online registration, document upload, progress monitoring, dashboards for students, supervisors, and coordinators, document archiving. Functionality testing showed that all features operated as required, while user satisfaction surveys indicated that 85% students, 90% supervisors, and 80% coordinators felt that the system improved convenience, efficiency, and transparency in KP and TA process. These findings indicate that the system successfully addresses manual administration issues and serves as a foundation for the future development of broader digital academic system.
