Abstract

Software Defined Radio (SDR) merupakan teknologi yang memberikan fleksibilitas tinggi dalam sistem komunikasinirkabel dengan memungkinkan perangkat keras yang dapat dikonfigurasi ulang dan diprogram melalui perangkat lunak.Fleksibilitas ini memungkinkan berbagai standar komunikasi untuk diadaptasi tanpa memerlukan perubahan padaperangkat keras. Namun, fleksibilitas yang tinggi ini juga membuka potensi besar terhadap berbagai kerentanannya,termasuk serangan jamming, replay attack, eavesdropping, dan spoofing yang dapat merusak integritas, kerahasiaan, sertaketersediaan data dan sistem. Penelitian ini bertujuan untuk melakukan simulasi terhadap berbagai serangan yang dapatmengancam sistem SDR dan menganalisis efektivitas strategi mitigasi yang diterapkan. Hasil simulasi menunjukkanbahwa proteksi berbasis kriptografi dan autentikasi digital dapat secara signifikan mengurangi potensi gangguan padasistem. Beberapa rekomendasi yang diusulkan untuk meningkatkan keamanan SDR meliputi validasi digital, pengelolaansertifikat, manajemen memori, dan deteksi intrusi.

Abstract

Permasalahan pengelolaan sampah masih menjadi isu penting, khususnya terkait pemilahan jenis sampah sejak tahap awal. Pemilahan sampah logam dan non-logam secara manual dinilai kurang efisien dan berpotensi menimbulkan kesalahan. Oleh karena itu, penelitian ini bertujuan untuk merancang dan membangun sebuah prototipe alat pemilah sampah logam dan non-logam secara otomatis berbasis mikrokontroler dan sensor. Metode penelitian yang digunakan adalah metode rancang bangun prototipe dengan pendekatan eksperimental. Sistem dirancang menggunakan sensor ultrasonik HC-SR04 untuk mendeteksi keberadaan objek dan sensor proximity induktif LJ12A34Z untuk mengidentifikasi material logam, dengan Arduino Uno sebagai pengendali utama. Hasil pengujian fungsional menunjukkan bahwa alat mampu membedakan sampah logam dan non-logam serta mengarahkan objek ke wadah yang sesuai secara otomatis. Meskipun terdapat keterbatasan pada objek dengan ukuran besar dan material campuran, prototipe yang dikembangkan telah memenuhi tujuan penelitian sebagai solusi awal yang sederhana dan aplikatif dalam mendukung pemilahan sampah otomatis.

Abstract

Abstract The security of assets in closed storage such as safes faces challenges in the form of illegal unit removal and physical manipulation. This study aimed to design and evaluate an anti-theft alarm system based on the Arduino Uno microcontroller with an SW-420 vibration sensor. The approach used was a laboratory experimental method focusing on testing the system's responsiveness to low-intensity mechanical interference or "Level Easy". The results showed that the integration of the SW-420 sensor, relay module, and buzzer successfully detected physical anomalies in real-time with a response time of less than one second. The implementation of the pulseIn() function in the programming logic proved effective in processing digital vibration signals into accurate alarm activation instructions. Threshold adjustments via potentiometers and the application of debouncing methods successfully minimized the potential for false alarms. In conclusion, this prototype demonstrated high reliability as an independent and portable early warning system for the protection of static assets.  Keywords : Arduino Uno, SW-420 Sensor, Safe Security, Vibration.

Abstract

Room temperature control is an important aspect in maintaining user comfort and ensuring the efficient performance of electronic devices in enclosed spaces. Manual fan operation is considered ineffective because it cannot respond promptly to temperature changes and may lead to energy inefficiency. Therefore, this study aims to design and implement an automatic fan control system based on room temperature using an LM35 temperature sensor and an Arduino Uno microcontroller. The control method applied is threshold-based control, in which the fan automatically turns on or off according to a predefined temperature limit. The system consists of an LM35 sensor for temperature sensing, a microcontroller for data processing, a relay module as the actuator controller, a DC fan as the cooling device, and an I2C-based LCD as the display unit. System testing was conducted in an enclosed room with naturally varying temperature conditions. The experimental results show that the system is capable of reading room temperature stably and in real time, displaying temperature data clearly, and controlling the fan automatically and consistently according to the room temperature conditions. Based on its performance, the proposed system can be considered a simple, efficient, and easily applicable solution for room temperature control in small- to medium-scale enclosed environments. Keywords: temperature control, automatic fan, LM35 sensor, microcontroller, embedded system.
