Cloud storage is a development of cloud-based data storage, then Firebase provides services, one of which is Firebase storage, which is one of the technologies in the field. Cloud storage technology allows Android users to store data without requiring physical storage, specifically for Android users themselves the use of cloud storage will be very useful as an alternative storage media or backup media so that data is not easily lost. The design of cloud storage applications using Android-based firebase was developed beginning with analyzing needs, designing the appearance of applications, building applications, inputting program code, and testing applications. Output results to be achieved are the generation of cloud storage applications that can store various types of file extensions, are easy to use, and can run well on the Android platform. From this research, the results are obtained: first Cloud Storage technology is very useful as a data storage medium so that data is not easily lost, secondly making an Android application with Angular can be built with Cordova to run on the Android platform, thirdly Firebase has many features and services that can be used in the development of android applications, one of which is firebase storage.

Entering 2020, the corona virus outbreak is spreading very quickly throughout the world, including Indonesia. This encourages the Indonesian government to make efforts and take handling policies to suppress the global spread of the corona virus or Covid-19. These policies did reduce the number of spreads but created new problems, such as increasing criminal acts and coupled with assimilation rights policies (freeing prisoners) during the Covid-19 pandemic which also resulted in an increase in crime rates, such as theft with weighting, motor vehicle theft, theft accompanied by violence, mugging, to beheading. One of the reasons for the increase in theft cases is the use of the situation when everyone is focused on handling Covid-19 and also the existence of security gaps. The security gap can be minimized, one of which is by developing technological innovation, therefore the author proposes a prototype for the development of a dual security system on two-wheeled vehicles with the latest technology. The results of the study, the system can provide notification information through the WhatsApp Messenger application in real time, as well as vehicle owners can control the vehicle remotely using the android application.

Mencari tempat parkir sungguh memakan waktu dan biasanya lebih menimbulkan kemacetan dan polusi udara yang diakibatkan kendaraan berada pada posisi tertentu dalam waktu lama hanya untuk mencari tempat parkir yang kosong. Saat ini di beberapa pusat perbelanjaan di kota besar di Indonesia sudah menyediakan sistem parkir yang memberikan informasi kepada pengendara mengenai jumlah tempat parkir yang tersedia atau tempat parkir sudah penuh. Walau demikian sistem parkir ini masih memiliki kekurangan yaitu pengendara tidak mengetahui secara spesifik dimana akan parkir. Dalam penelitian ini dikembangkan sistem parkir yang dapat membantu pengendara menemukan tempat parkir. Informasi tempat parkir terdekat dengan pintu masuk bangunan akan tertera pada tiket saat pengendara menekan tombol tiket di pintu masuk. Pada tiket tersebut tertera blok dan nomor slot parkir yang disarankan. Sebelum pintu masuk akan disediakan tampilan LCD sebagai monitor yang memberikan informasi jumlah lokasi parkir yang tersedia. Dalam pembuatan alat simulator sistem monitoring ketersedian tempat parkir yaitu dengan menyiapkan Arduino Uno, Servo dan sensor IR Obstacle. Pada simulator ini akan menghitung jika kendaraan masuk melalui pintu masuk dan akan berkurang jika kendaraan melewati pintu keluar. Berdasarkan hasil pengujian yang dilakukan terhadap sistem menunjukan bahwa aplikasi telah berjalan dengan baik dan sesuai dengan apa yang diharapkan.

Storage is one of the security measures that aim to maintain and maintain product quality. In the bread storage room, for example, the quality of bread has been determined in the preparation of the bread dough ingredients and also the temperature and humidity of the room which must be maintained. The problem that often occurs is that the employee in charge of monitoring the room is constrained by the location of the distance between the storage room and the remote monitoring room, while data from room temperature and humidity must be reported to the monitoring officer to ensure the quality of the production material. One of the efforts to ease this problem is to build a real-time humidity and temperature monitoring system that makes it easier for employees to work in storage rooms remotely without having to come directly. One of the current technological developments is the IOT (Internet Of Things). The IOT concept can be used to make it easier for employees to monitor the temperature and humidity of storage space through web-based applications and android applications. Humidity and room temperature monitoring system application by working in accordance with the programming instruction sequence and monitoring system control using a user interface in the form of web-based applications and realtime android applications. The system application obtains temperature and humidity data from the server data which is then displayed on the interface so that it can be monitored in realtime.

Game is something that is used to play which is played with certain rules. Game is a game that uses electronic media, is an entertainment in the form of multimedia that is made as attractive as possible so that players get something so that they get inner satisfaction. But behind these advantages, educational games also have drawbacks, namely very minimal interest from the public in educational games, this is because most users or the public think that the game is boring and uninteresting, and this has become the mindset of the community since this educational game was first introduced. appears, besides programmers who make educational games are still very few compared to programmers who make non-educational games. Therefore, the author proposes an educational game application that can be of interest to students by making the game look as attractive as possible so that when playing the game you can see an attractive appearance. The results of the research are an Android-based application for the introduction of Lampung Province Traditional Musical Instruments which can help people learn more about Lampung traditional musical instruments, besides the system shows that the game application has been running well.
