  Abstract —Android-based smartphone is the device that widely used by people, especially in Indonesia. A smartphone not only lets someone

  make telephone calls but also easy to access the internet, send and receive an email, open social media accounts like Facebook, Twitter and others. In addition, many chat applications such as Whatsapp, Blackberry Messenger, Line and others can also be run via a smartphone. Moreover a smartphone also can be utilized in monitoring and controlling a system in various fields such as education, transportation and so forth. In this research, an android-based smartphone was implemented for the information of lecturers existence. When a lecturer is very busy, it is difficult for the students to meet them to discuss about their study. The students do not know their lecturer existence, whether they are teaching, meeting or even be out of town. They often spend their time to wait for the lecturer. If they know the lecturers existence, they can spend their time for useful activities. Based on this case, lecturers have been created an application that will facilitate them in telling their existence. The Application is also provided for students and others that allows them to know the existence of the lecturers. This application was designed using an Android Studio Program, while the web server was built using Xampp Software. In the initial stages, this application is running on local host only. This is done to ensure the system is running as desired before will be realized online via the internet. This research has resulted The applications that are easy to use by lecturers and students. Hopefully, the implementation of this application can contribute to the smooth communication between students or academicians with lecturers, so that the teaching and learning process goes smoothly.

  I NTRODUCTION Every University wants to finish its students on time with a good GPA (GPA) and get the job as fast as possible. To achieve this goal, universities should create a good education system, starting from the process of proper admission, planned and controlled teaching and learning process and good academic atmosphere. Besides that, the other important thing is communication between students with lecturers, education staff and leadership majors or other unit leaders in the college must run smoothly. But sometimes because of a very busy, students have difficulty meeting with lecturers to consult about the teaching and learning process. Students sometimes do not know the existence of the lecturers they will meet, whether teaching, meeting or even being on duty outside the city. If they know the existence of the lecturers they will meet, they can use that time by doing useful activities. Actually in some institutions already have an information system about the existence of officials who are there, but the information is still limited presence or absence of officials concerned and still done manually. Meanwhile, information about the existence of the lecturers is still very rare. The same problem was encountered in several universities. Besides, information technology is developing very fast. The information needed is faster obtained or accessed through the internet using a smartphone or other communication devices. Should the above problems can be solved by utilizing a smartphone that is mostly based on the

  Android operating system. In a company, a manager will more easily monitor the activities and behavior of employees while working using this Android-based Smartphone [1]. Through the features of this device, the tracking of one's existence can also be done [2]. Smartphone utilization today seems to have become a primary need in everyday life. Smartphones are not only used for communication, but also used in various fields such as monitoring and controlling a system, such as a smart house system that has been developed by researchers and industry practitioners. The Android app is built to monitor and control doors, windows, temperatures, light intensity, movement and electrical energy consumption [3]. This system is built to provide services to humans, especially for people with disabilities and the elderly [4]. In fact, the advanced technology used in this smart house is intended to provide comfort and security to humans in performing daily activities [5]. Bluetooth facilities, existing WIFI on smartphones are often used for communication between controlled equipment. Similarly, in the field of transport, the Android app is also used as a tool for tracking the positions of a bus or public transport [6] and guides in providing route information [7]. The Android app also applied to the provision of tourist information, hotels, restaurants, historical places and so on that tourists can use in traveling [8]. In addition to the health sector, Android applications can be used as a sender of initial information by healthcare workers or the public to the hospital when a patient with an accident or heart attack is still on his way to hospital [9]. The Android application on the smartphone is used to monitor and control patients who experience leg orthosis while doing the exercise on the physiotherapy process [10]. In the world of education, Android applications have also been applied to create teaching modules in the field of electrical engineering [11]. Through the teaching module, students can learn about the topics delivered and also can try to complete the exercises provided. Based on the above problems and the utilization of Android applications in various fields, then made an android application that is implemented to provide information about the existence of lecturers. The aim of this application to facilitate lecturers in informing their existence, and also allows students to know the existence of lecturers they want to meet.

  II. MATERIAL AND METHOD/ALGORITHM THE

  In this study, App Inventor is used to create applications The Android app for lecturer information is created using for lecturers in providing information on its existence and

  MIT App Inventor. This free software can be obtained application for students to know the existence of lecturers through the website http://ai2.appinventor.mit.edu. The who want to meet. Applications created for lecturers consist software is divided into two parts, namely the designer part of five menus are login menu, register menu, data entry menu, and the blocks part [12]. In the designer, menus that will be information search menu and search result menu. used as user interface can be designed. Features such as

  The login menu is used to enter the username and password buttons, labels, textbox and so on can be selected depending of the registered lecturer. On this menu also provides a link to on the desired conditions. Likewise with the process of register for lecturers who have not registered and links to find connecting, data storage, sensors used to support applications out the existence of lecturers who have entered the that want to designed also been provided. The menu designer information existence. The design of this login menu is shown ini The menu designer is shown in Figure 1 below. in Figure 3.

  IV. AND DISCUSSION RESULT figure 10. This study has produced an Android app that can be used by lecturers and students. Lecturers can enter their existence information and students can get information on the existence of the lecturer.

  Actually, the Interfacing program of Android application is almost the same with the program of the information system through the website. Web servers, user interfaces, and databases are required. Web Servers that use Xampp Applications are selected for free and general public licenses. Besides, this software running on the background side, and does not disturb other systems and keep running, although the system is logged-off.

  It's just that the characteristics of this Android app are a simple and light to be accessed, compared with the version of the website is more complete and somewhat heavy when it wants to run. Therefore the menus are made on Android app is also simple and easy to use, so the lecturers can quickly enter the information of its existence. Besides that, the App Inventor is also chosen because it is free and easy to use. Applications can be built online without us having to install the application program on the computer. In addition, the App inventor also does not require high computer specification in building this application.
