Abstract

Indonesia, most cyber incidents reported by respondents relate to loss or leakage of business information such as internal records, information related to customers, employees and intellectuals. This worries the misuse of information held by irresponsible parties. in order to protect information so that it is not misused by unauthorized parties, then an attempt is made to hide the actual information on other information called steganography by using the Least Significant bit (LSB) method and to see the image quality value containing the message using the MSE calculation (Mean Square Error) and PSNR (Peak signal to noise ratio). The process of inserting messages is successfully carried out and produces extraction steganographic images. From testing the picture it can be concluded that the results of the steganography application must be invisible or not visible in plain view, as the purpose of this study is to increase the security sent to arrive at the recipient.

Abstract

The campus area is a place for students and teaching staff to carry out their routine activities. But there are times when campus visitors are not only focused on teaching staff or students who already know the ins and outs of the campus area. Some parties such as students' parents, new students, guests sometimes need a certain guide to find specific areas of interest in the campus area. The development of this application is carried out aiming to assist and alleviate these parties to search and find related areas. The design of the software is made with Adobe Edge Animation CC with Action Script 3.0. based on the results of this study it can be concluded that the Digital Mapping Application on the Muhammadiyah Riau Campus can overcome the problem of confusion among the parties when visiting the Muhammadiyah Riau campus.

Abstract

Forest and land fires in Riau Province are a serious problem and can cause losses to humans and nature. It is necessary to design an Internet of Things (IoT)-based land and forest fire detection device using an independent power supply energy source. This device is equipped with DHT11 temperature sensor, MQ2 smoke sensor, and flame sensor, as well as LoRa SX276 module as data transmission media. The system utilizes IoT technology to monitor real-time environmental conditions and provide a quick response to potential fires. A standalone power supply energy source is implemented to increase the independence of the device, so that it can operate effectively in emergency situations. The LoRa SX276 module is used as a data transmission medium to enable remote communication and ensure device connectivity with the control center. Device testing was conducted through simulated fire scenarios to evaluate its performance in detecting high temperature, smoke, and fire, as well as the reliability of data transmission over the LoRa network. The results show that the device successfully detects fires with a high level of reliability and is able to transmit data efficiently over the LoRa network. The contribution of this research is the provision of an advanced and reliable fire detection solution using IoT technology and self-sustaining energy sources, with the ability to transmit data over long distances via LoRa modules.

Abstract

The growth of eggplant plants is greatly influenced by environmental conditions, especially pH and soil moisture. These parameters need to be monitored regularly to ensure optimal conditions for the plant. In this study, an Internet of Things (IoT)-based monitoring system was developed to monitor soil pH and moisture in real-time. The system uses pH sensors and humidity sensors connected to microcontrollers and combined with IoT connectivity to send data to a cloud platform. The data collected can be accessed through a mobile application, allowing farmers or land managers to monitor soil conditions remotely. The results of the implementation show that the system is able to provide accurate and real-time information on soil pH and moisture, as well as provide notifications when these parameters are outside the optimal range. With this system, it is hoped that farmers can take corrective action quickly to maintain the condition of
