Abstract—Attendance is a must for students.
Without the attendance process, the lecturer or teacher cannot assess the
participation of a student. But in the process now, attendance is still done
manually using paper. Where later the paper will be signed by students. But
this will cause problems. The first problem is the use of excess paper and the second
problem is the difficulty for the administration to recapitulate student
attendance results. This is because so many attendance papers must be analyzed
by the administration. Therefore, a student attendance system is needed that
can collect data quickly, efficiently and accurately. This student attendance
system is done by conducting data collection, system analysis, system design,
and system implementation. This system is created using the PHP and Java
Android programming languages. The System is also using Ibeacon as classroom
identifier. The purpose of this study is to make attendance system applications
of students and class schedule notifications based on IBEACON, it is expected
that the attendance process will be more efficient and can be easily monitored
by lecturers and by the central administration. . Keywords—Attendance,
Application, Ibeacon, Schedule
I.INTRODUCTION
iBeacon is a name for Apple technology
standards, which allows Mobile Apps (running on both iOS and Android devices)
to listen to signals from beacons in the physical world. Basically, iBeacon
technology allows Mobile Apps to understand their position on the micro-local
scale, and deliver hyper-contextual content to users based on location. The
underlying communication technology is Bluetooth Low Energy or commonly called
Bluetooth beacon. Attendance is an activity of data retrieval in order to find
out the number of attendance in a course. Every activity that requires
information about students will attend attendance. This also happens in the
learning process. The usefulness of this attendance happens to students and
parties to the teaching and learning process. One of the uses of this
attendance system to students is, among other things, in calculating the
likelihood that students will take exams and one of the uses of this attendance
information to those who are teaching and learning activities, among others, to
evaluate students' satisfaction with a subject and create benchmarks for the
future. giving better knowledge. Retrieval of attendance data itself is done
manually has many shortcomings, Another disadvantage of manually retrieving
data is the loss or damage of existing data. Another disadvantage is the lack
of efficiency and effectiveness in data processing [2]. The use of mobile and
web applications is said to be more effective and efficient because of the ease
in accessing and retrieving information. In addition, with the addition of
IBeacon technology that has location-based features, we can base the attendance
process on classrooms and subject schedules on the class, so the information
submitted is not only limited to attendance but also information about class
schedules and lecturers who teach the course. https://codeshoppy.com/shop/product/
II.LITERATURE
REVIEW
A.API The Application Programming
Interface (API) is a set of visible code elements provided by a framework or
library, and such libraries or frameworks are called API libraries. API
libraries are also referred to as API codes [5]. Client Code is an application
code that reuses or expands the code elements provided by the API library [5].
API Usage is a way to call the API code, which includes the sequence of calls
or invariants [5]. So it can be said that the Library API is called by the code
or script provided by the user, in this case, the author of the application by
using the methods or procedures that exist in the API Usage. the REST API is
based on REST architectural style, which is using text-based JSON message over
HTTP transport [6]. Application Programming Interface (API) is defined as interfaces
used by the software component to communicate with each other [7]. B.IBeacon
iBeacon works with Bluetooth Low Energy (BLE), also known as Bluetooth 4.0 or
intelligent Bluetooth. Through iBeacons, we can identify our position in a shop
and it could send us notifications about things that are going to be sold or we
are interested in. Besides, we could pay without coming up with the money from the wallet or without using a
credit card. So, it could be a possible rival of the Near Field Communication
[3]. C.Line Messaging API Messaging API allows data to be sent to your bot's
app server and the LINE Platform. When a user sends a bot you have with a
message, a Webhook will be triggered and the LINE Platform sends a request to
your Webhook URL. Your server then sends a request to the LINE Platform to
respond to user requests. Request sent via HTTPS in JSON format [8].D.Smart
Campus A smart campus is similar to the smart city and same solutions can be
used in smart campus applications. “Smart campuses are built to benefit the
faculty and students, manage the available resources and enhance user
experience with proactive services [1]. Smart campus refers to integrating all
kinds of application services systems, setting up a wise, intelligent teaching,
learning, and living environment, which is suitable for: management, teaching,
scientific research, and campus life unity, as well as based on the Internet of
things [2]. E.Android Android is a mobile platform developed by OHA “Open
Handset Software Alliance”, whose most influential member is Google. It is
open-source software, meaning that anyone can download the source code from
AOSP (Android Open Source Project) and use or modify it. Android can be roughly
separated into the following major components: Applications, Application
Framework, Libraries, Runtime, and Linux Kernel [4]. F.BLE Due to the feature
of low energy consumption, it is widely used for IoT services. The
specification of the Bluetooth system defines three channels used for BLE
Advertisement. This leads to high signal collision rate when there is a large
number of BLE devices in a narrow area. As a consequence, the discovery latency
for all surrounding BLE devices is extended. Meanwhile, the signal density
increases with the increasing of BLE devices which leads to a short delay in
capturing a Signal [9]. BLE inherits a majority of the design of classic
Bluetooth in terms of the protocol stack, data structure, and working band,
while BLE involves several important changes towards a simple short-range radio
network [10], [11].
III.PROPOSED
METHOD
The analysis is the first step for
developing an application because the design and even the development of an
application implementation will not run well without an analysis of the
application to be used. Analysis can also be defined as the stage of
explanation of a complete application with a view to identifying and evaluating
problems and obstacles that occur as well as the expected needs so that there
are proposals for improvement. In this analysis, the phase has the purpose of
knowing the system of the application that has been made, the processes
involved in the application and the relationship between processes. The system
analysis stage is a critical stage which is very important because errors in this
stage will result in the next stage. A study proves that errors that are
corrected after the analysis phase will have a greater cost than if corrected
during the analysis. The first step is to do an analysis of the ongoing
process. At this time, the student attendance process is still done manually.
Students must sign an attendance form that has been provided by the campus or
university. This raises two problems, namely: 1) The student attendance
calculation process is longer. This is because, the administration department
must calculate one by one the number of student attendance by the department,
by faculty and overall. 2) Wasteful paper, this manual attendance process is
not environmentally friendly and wasteful of paper because of a large number of
papers used to be as attendance forms. Fig.
1.Current Process Of Attendance Figure
1 explains the current student attendance process, this process starts when
students enter the class. After that students will be given an attendance form,
students will then sign the form, after that the lecturer will check and verify
by calling one by one of the students who are present. The attendance form will
be used to calculate attendance for each student. After the calculation process
is carried out, the administration will input the recapitulation data into an
excel file, where the file will be used as a reference to show the student
attendance level. In the current attendance process, there are 3 actors, namely
students who attend the attendance process, BAAK or the administrative
department that manages attendance data management, as well as lecturers who
carry out verification of attendance by students.
After Bluetooth is activated the application
will check the existence of IBeacon. IBeacon functions as an identity for each
classroom in the lecture building. Each existing IBeacon represents information
about the name of the room, the room code, and what courses are registered in
the room. If IBeacon is detected, a notification will appear on the user's
smartphone, the notification contains information about the name of the room
where the IBeacon is located. At the time the notification is clicked, the user
will be directed to the course schedule page, on this page the user can view
the course schedule and information in accordance with the classrooms that have
previously been identified. After that students can do the attendance process
by logging in first. After the login is successful, the user will be directed
to the schedule page, on this page the user can choose a schedule that matches
the classroom, day and hour, after selecting the schedule, the user will be
directed to the attendance page. Users only need to press the attendance
button, then the attendance process will be carried out. After the attendance
process, the user will be directed back to the schedule page and will
automatically log out of the system. After that, the lecturer will receive a
notification regarding the attendance process that has been done by the
student
There
are several criteria that must be met by users when they want to attend
attendance, namely:
1)Attendance
Process Can Only Be Done In Classrooms, Days, and Hours That Are In Accordance
with the Time of the Day.
2)Users
can only attend attendance at the subjects they have taken at the time they
input KRS. So even though there are two-course schedules in certain classrooms,
users cannot attend attendance if the user is not registered as a participant
in the course.
3)Attendance
Process Can Only Be Done One At The Time. Students who have been attended by
today's schedule can no longer attend attendance.
If
these criteria are successfully met then the user will be able to attend the
attendance process
For lecturers, they can only see
notifications given by students and see schedules based on rooms and buildings
where the lecturer teaches. For students, they can only log into the system and
attend attendance processes based on the class in which they have been
registered, besides that students can also view the course schedule based on the
room and building. For BAAK administrators, they can manage content in the form
of subjects, classrooms, schedules, students, lecturers and attendance results
that have been done by students. The system to be built is divided into 4
parts, namely:
1.
Bluetooth Detection Component
This section serves to detect the existence of IBeacon, this
component includes android applications, CuBeacon and BLE (Bluetooth Low
Energy) or Bluetooth 4.0.
2.
Line WebHook Components
This section functions to handle requests sent from the
application to the Line Messaging API, this section forwards notifications
regarding the process of attendance from the web to the Line. This component
consists of Line, Line Messaging API, and Line Webhook.
3.
Website Administrator
This section serves as a place for managing data regarding
attendance which will be used by the other 3 components. This component becomes
the basic information’s provider. This section is managed by admin or BAAK.
4.
Front End Application
This section functions as the main application, in this
section students, can see the schedule and do the attendance process
