Abstract

This article presents the development of SIDASIBELO (Landslide Information and Mitigation System), an Android-based application for real-time landslide monitoring and early warning. This system integrates data from several sensors that measure soil moisture, rainfall, slope angle, and ground vibrations at the monitored locations. The Firebase Real-time Database stores and transmits sensor data, while Firebase Cloud Messaging and OneSignal enable push notifications to alert users about potential landslide risks. There are four output status levels: SAFE, ALERT, CAUTION, and WARNING, which are determined based on a comprehensive analysis of the monitored parameters. Mitigation strategies include real-time parameter monitoring, early warnings, evacuation guidance, and user education on landslide preparedness. Testing on several Android devices demonstrated high compatibility, with an average successful server connection rate of 92.86%. Latency tests indicated an average response time of 894 ms from the input device to the database, 1.29 ms from the database to the Android device, and 2725 ms for push notifications. The system's total daily bandwidth usage for real-time data transmission is 27,648 MB, indicating high efficiency without overburdening the server's performance. While the app operates efficiently under ideal conditions, unstable network connections can lead to data retrieval failures or, in worst cases, app malfunctions. This remains a key challenge for our system. This system aims to raise awareness of landslide risks and enable timely evacuation, which could potentially reduce the negative impacts of landslides in vulnerable areas.

Abstract

In the industrial era 4.0 where everyone is competing to adopt technology making them inseparable from our lives. Likewise, the trading or buying and selling sector has emerged where new buying and selling places have emerged that use technology using the internet network as the basis for their operations. This platform was then called e-commerce. The aim of this research is to find out what students' views are on buying and selling transactions in e-commerce based on an Islamic religious perspective. The method used is a descriptive method with a qualitative approach by collecting data from sources through interviews on WhatsApp. The students studied were students studying in the Electrical Engineering study program at the Indonesian Education University. The interview results showed that all interviewees used e-commerce as a platform for buying and selling online. The speakers also agreed that e-commerce platforms in Indonesia are in accordance with Islamic religious law, while those that do not comply with Shari'a are on the seller's side who sometimes still trade dishonestly. The source also said that the paylater payment method should be avoided because it contains elements of usury and can make our transactions haram. Thus, it can be concluded that buying and selling transactions in e-commerce are permissible as long as we follow the pillars and conditions of buying and selling in Islam and avoid transactions that contain elements of usury, gharar and fraud.
