Kata kunci: Irigasi Tetes, Kelembaban, IoT, Firebase, Spreadsheet ABSTRACT Cayenne pepper plants can grow optimally at 60%-80% soil moisture with an average air temperature of 18 – 30 degree celcius. The current watering still uses a manual system which will result in a loss of time and effort. In addition, manual watering also wastes water and can make plants wither. In this study, a system is proposed to help maintain the humidity of chili plants by using gravity drip irrigation techniques that can be monitored online and in real time on an android application and google spreadsheet. The test results show that this system is able to maintain soil moisture at a value of 60%-80% with the volume of water used as much as 26.67 milliliters/minute. The average results of all sensor and servo motor accuracy tests produce a fairly good value with an average error of 1.96% and an accuracy of 98.04%. Furthermore, the QoS test results for delay are in the good category with an average of 177.99 ms and packet loss is in the very good category with a value of 0.02%.

Helmet theft is a problem that is of concern to the public. Information Technology provides may resolve any problems, like Internet of Things-based system that can detect helmet theft and track the ...location of the helmet if it's stolen. This system is designed using a microcontroller device, namely Arduino which is attached to the helmet and motorbike with the help of the SIM800L v2, GPS Neo-6m, buzzer, and Bluetooth HC-05 which is connected to the master slave as an indicator of the safety of the helmet. The hardware on the helmet is connected to Firebase Realtime Database server so it can be connected with the user's Android application to monitor the state and location of the helmet. Android application displays maps to determine the position of the helmet, and can display notifications when the helmet is being stolen. The conclusion is this system can detect helmet theft with a maximum distance from the master and slave bluetooth connections of 10 meters, and the average data transmission from hardware to Firebase is 1,1 seconds, and can monitor status of the helmet and track the position of the helmet through the Android application with Android Jelly Bean (v4.3) operating system.
This paper presents a practical design of backdoor to permanently bypass the screen lock mechanisms on Android devices. Our design has many advantages such as difficulty in detecting backdoor, fast ...execution time and low power consumption. The key feature of our backdoor is remote triggering that allows the backdoor to be temporarily triggered and executed through push notification services also used by many normal applications. Furthermore, in our proof-of-concept backdoor, about 98% of 4-digit PINs and screen lock patterns were cracked within 5 seconds, and only a small amount of power was consumed. We show the stealthiness of our backdoor to effectively evade the existing malware detection tools (55 anti-virus scanners provided by VirusTotal and SandDroid).
The transformation of existing infrastructure into smart cities cannot ignore the smart management of the parking systems. The cities with high population density (Metro cities inclusive) ...specifically face the problem of finding the nearest available parking space. The rising number of vehicles daily makes this problem more severe that questions the safety of vehicles as well. In this study, the issue of finding parking spaces in smart cities is addressed using an IoT-based methodology. The proposed Intelligent Parking System (IPS) consists of an IoT framework that collects real-time data, send it to the cloud, and thereby suggests to the user a suitable place for parking the vehicle at a nearby location. As a component of the framework, a mobile application has been developed that enables users to check the availability of nearby parking spots and subsequently reserve a parking place. This paper also describes different use-cases of a person for finding a parking space and parking it in right place. The proposed system has been implemented using Raspberry Pi, NodeMCU, Radio Frequency Identification (RFID), and Infrared (IR) sensors. The results discussed in the later sections support the usability of this IPS.
Managers of universities have a responsibility to ensure that parking is available for all stakeholders, particularly students. When there is not enough parking space for the quantity of vehicles ...arriving, issues occur. Consequently, the atmosphere was no longer favorable due to the pandemonium of vehicles that had taken over. This research's objective is to create a working prototype of an vehicles parking system that can control the flow of vehicles into the campus area. This system's controller is a Wemos D1 Mini, which may be used with the ESP 8266 module to connect to the internet, RFID card for students' identities for drivers of motor vehicles, servo motors to control gateways, infrared proximity sensors to count the number of vehicless entering and exiting the parking area, and Google Firebase for student lecture scheduling databases are all examples of technology used in parking area today. The test results reveal that the system can successfully verify the schedule saved in Firebase and read the student's identity contained on the RFID card. Only students with class schedules on that day are permitted access to the parking area.
Traffic violations are familiar things on the highway. For road users who commit traffic violations will be given sanctions such as reprimands, warnings or given a ticket. The speeding ticket is a ...medium for the police to write fines and violations against road users who commit traffic violations. In this modern era ideas and ideas have emerged to develop a system or application that can facilitate the performance, needs and human activities through an intermediary smartphone. E-ticketing is a digitization of the manual ticketing process that fills offenders data on the ticketing sheet. The e-ticket helps the police in the ticketing process by entering data in the application, utilizing the Firebase Realtime Database technology through smartphone intermediaries. The purpose of this study is to create a traffic violator or E-ticketing system using the Firebase Realtime Database technology. Then provide attachments to offenders in the form of notifications through the E-ticket application, and assist the police in an effort to deal with traffic offenders. The results of this study showed 80.5% of respondents rated the Application of Firebase Realtime Database on the Android-based Smartphone Mobile E-Ticket Application in accordance with the needs of the police in carrying out the ticketing process.
The presented paper describes the creation of a mobile application module for showing a current menu at Mendel University cafeterias. Nowadays, the students and the university staff have the menu ...accessible through a static webpage. The presented solution serves as a dynamic presentation of the current menu for all Mendel University in Brno cafeterias. Most cafeteria menu applications use the REST architectures for the server backend. The contribution of the paper is in usage of the Google Firebase Realtime database as a server backend. Unlike in traditional REST architecture, the data e.g. the food rating is instantaneously changed and the users have an up to date information. Part of the presented solution is also a mobile application module for both Android and iOS where university students and staff can see the current cafeterias menus.
Smartphones and tablets are steadily changing the way we look after our education. Today penetrating further deep into the market study of mobiles require application related to educare. EDUSET team ...wants to develop a mobile application on MBA university guidance which provides the user with basic university information. A person’s usage of this application helps him/her to begin a good career. Firebase is used as database and android studio as a platform to develop the app. There are many apps regarding MBA learning but there will be no app like EDUSET. This application of this Android Platform is capable of guiding and suggesting the user with university information based on his/her probe. This application also enables individuals to become aware of different universities and its activities. The user will be provided with search option where he/she can probe according to university name or any of the MBA courses.
