Following the global pandemic of COVID-19, in August 2021, Indonesia achieved a total of 3.930.300 cases, the highest in Southeast Asia. However, the government is keen on promoting the new normal ...phase and planning to open schools and permit face-to-face learning, from elementary up to universities. This means that public facilities and infrastructures will be used and can be the medium for virus transmission, as it will require 48 to 72 hours for the virus to be inactive on those surfaces. This will make people reluctant to touch surfaces, especially when it comes to public facilities that can provide for their needs. One of the most important is the need for hydration which is often overlooked. About 25% of college students were found dehydrated, and 37,5% showed signs of it. Dehydration could prove a serious threat to health had it been overlooked and could affect physical and cognitive performance, having more effects on students and lectures, requiring both in their activities. To support the needs of hydration amidst the pandemic, this research developed a touchless water dispenser system using the waterfall model, utilizing a cloud database with ESP32, controlled by users through an android application. The design is easy and cheap to install, even on regular dispensers, making it an effective and efficient alternative public facility providing hydration service to support the new normal phase.
We present DNADroid, a tool that detects Android application copying, or “cloning”, by robustly computing the similarity between two applications. DNADroid achieves this by comparing program ...dependency graphs between methods in candidate applications. Using DNADroid, we found at least 141 applications that have been the victims of cloning, some as many as seven times. DNADroid has a very low false positive rate — we manually confirmed that all the applications detected are indeed clones by either visual or behavioral similarity. We present several case studies that give insight into why applications are cloned, including localization and redirecting ad revenue. We describe a case of malware being added to an application and show how DNADroid was able to detect two variants of the same malware. Lastly, we offer examples of an open source cracking tool being used in the wild.
In the era of Industry 4.0, remote monitoring and controlling appliance/equipment at home, institute, or industry from a long distance with low power consumption remains challenging. At present, some ...smart phones are being actively used to control appliances at home or institute using Internet of Things (IoT) systems. This paper presents a novel smart automation system using long range (LoRa) technology. The proposed LoRa based system consists of wireless communication system and different types of sensors, operated by a smart phone application and powered by a low-power battery, with an operating range of 3–12 km distance. The system established a connection between an android phone and a microprocessor (ESP32) through Wi-Fi at the sender end. The ESP32 module was connected to a LoRa module. At the receiver end, an ESP32 module and LoRa module without Wi-Fi was employed. Wide Area Network (WAN) communication protocol was used on the LoRa module to provide switching functionality of the targeted area. The performance of the system was evaluated by three real-life case studies through measuring environmental temperature and humidity, detecting fire, and controlling the switching functionality of appliances. Obtaining correct environmental data, fire detection with 90% accuracy, and switching functionality with 92.33% accuracy at a distance up to 12 km demonstrated the high performance of the system. The proposed smart system with modular design proved to be highly effective in controlling and monitoring home appliances from a longer distance with relatively lower power consumption.
