Abstract

The surfaces of three major tectonic plates the Eurasian Plate, the Indo Australian Plate, and the Pacific Plate intersect in Indonesia. This condition creates a high risk of earthquakes and landslides in areas located at these plate boundaries. The urgency of this research lies in developing a landslide detection device to help communities living in landslide-prone areas remain alert to disasters that may occur at any time. The objective of this study is to develop an Internet of Things (IoT)-based landslide detection device powered by solar energy. This device does not rely on external power sources but utilizes solar energy as its primary power supply. The research employs an experimental method. The steps include problem identification, literature review, system development methodology, design and application development, testing, and analysis of test results.Landslide detection is carried out using vibration sensors to detect ground tremors that may indicate a landslide, tilt sensors to monitor changes in ground inclination, and soil moisture sensors to measure soil humidity. An Arduino microcontroller processes data from the sensors and transmits signals to the warning system, while solar panels generate electrical energy from sunlight. The use of solar cells is optimized by calculating the required energy capacity to operate the sensors, Arduino board, and early warning system.

Abstract

Digital images can be easily copied and distributed illegally using widely available software tools. A technique is needed that can be used to copyright protection. This technique can show the identity of the owner, so it can be used to track its authentication, namely the watermarking technique. Watermarking methods that embed side information into images with the aim of protecting copyright have been proposed. So far, these methods have been defeated by simple attacks such as rotation, translation and scaling. In this research, a novel digital image watermarking (DIW) system that takes advantage of the Wavelet Transform properties to embed a spread spectrum circular symmetric watermark in an image is proposed. Watermark is invisible, its mean imperceptible to the human eye but can be detected or extracted by software. Watermark robustness against translation, rotation, scaling, median filter, and adaptif filter attacks is achieved by the proposed method. Successful experiments showing the performance of the method to geometric transformation.
